    [001] The present invention relates to a vehicle wheel, which features a wheel with a wheel base made of fiber material and a wheel disc, the wheel disc being connected to the wheel by means of at least one connecting element, which is introduced through a passage in the rim of the rim and incorporated into the wheel disc.
    [002] The wheel disk may have a closed or open structure in the form of a star with positive union.
    [003] A device of this kind is disclosed in the EP 1 858 715 B1 form. In this vehicle wheel, a star-shaped wheel disc (center of the wheel) is connected to the rim with various connecting elements, which can be screws or rivets and are inserted individually into a through hole in the rim base. The connection inserted into the rim base is not visible from the inner side of the rim. To seal the pressure area, a seal, especially a seal, is provided between the connecting element and the rim base, as well as the through hole in the rim base.
    [004] The wheel center and the connecting element are directly connected to the rim base, which causes vibratory friction wear on the rim base material in the most frequent combinations of materials and under dynamic load during wheel operation of the vehicle. Due to the different stiffness ratios of the connecting element, wheel centers and rim base, relatively strong relative movements are expected during operation.
    [005] As a consequence, problems arise in the density of the connection, since the various stiffness ratios and the micro movements of the components considerably reduce the sealing effect of the connection under a continuous load. Due to deformations in the center of the wheel, for example, due to the paths in stone roads and passages with holes, specific high forces are transferred to the connection and sealing which further benefit the leaks. The connecting element and the seal are connected to the pressure area of the rim so that any leakage inevitably results in a loss of pressure in the tire and, in this way, it will pose a risk of accidents.
    [006] It is also disadvantageous that the composition of the especially viscoelastic seal has a tendency to strong creep under surface pressure and micro movements and, therefore, reduces the carrying capacity of the connection, causing the connection to come loose or even disengage.
    [007] The invention aims to eliminate the disadvantages of the vehicle wheel according to the latest technology and to provide, in particular, a reliable connection for safe operation of the rim with the wheel disc.
    [008] The objective is solved, according to the invention, by the fact that the rim has, for the connection with the wheel disc, at least one connection arrangement with at least one connecting element and, for the sealing of the tire chamber, a sealing element that covers, integrally and concave, a part of one or several adjacent connection arrangements extended by the outer side of the rim, as well as a circumferential margin of the sealing element is hermetically adhered to the rim base .
    [009] The sealing element according to the invention completely covers and covers the part of the connection arrangement adjacent to the outer side of the rim at the rim base or inserted in the outer rim of the rim at the rim base, the sealing element being superimposed with a defined and stable geometry forms a hollow area over the part of the sealing arrangement extended by the outer side of the rim and only one edge of the sealing element is adhered to the rim base. The sealing element is designed or protected, in a dimensionally stable way, significantly maintaining its geometry during the influence of the tire chamber pressure.
    [0010] The sealing element of the sealing arrangement can be, for example, a screw or a rivet inserted in the rim base, and therefore, the part of the connection arrangement extended by the outer side of the rim can be a screw head or a rivet head.
    [0011] The connection arrangement may comprise several combined connection elements and other connection elements, for example, bushings or a flat washer under the screw head, and these connection elements may also have a part of the connection arrangement extended by external side of the rim, which is, according to the invention, completely covered and furnished by the sealing element.
    [0012] The outer side of the rim is the side of the modified rim of the wheel disc.
    [0013] In a marginal area around the part of the connection arrangement extended to the outer side of the rim, the circumferential margin of the sealing element is arranged at the rim base and adhered to it, protecting the sealing element directly against the base of the rim. dine. Sealing can be carried out, for example, by adhering the inner area of the edge of the sealing element with the rim base and / or by sealing the outer area of the edge with the rim base, for example, with a coating of the margin or of the entire sealing element overlapped and up to the base of the wheel, with an adherent and impermeable layer. In any event, the direct or indirect adhesion of the sealing element to the rim base is uncoupled by the connection arrangement under a mechanical load, ensuring a safe and stable sealing effect.
    [0014] Therefore, the pressurized tire chamber of the rim, which is located on the outer side of the rim, is completely sealed against the connection arrangement, including the connecting element introduced into the passage, and separated from the external atmosphere.
    [0015] If several contiguous connection arrangements are installed in a group, for the connection of the rim to a star-shaped wheel disk, for example, the sealing element can cover and cover, in a concave arrangement, the parts of these arrangements grouped connection points extended by the outer side of the rim. Considering the process described above, the connection arrangements installed in a grouped manner are fully sealed, saving material and space with a single sealing element.
    [0016] The invention takes into account the fact that the main force flow to transfer the forces from the wheel disc to the rim is carried out during the direct friction process between the wheel disc, the connecting element and other associated parts by friction of the connection and the base of the window.
    [0017] In the arrangement and configuration of the seal according to the invention, the necessary sealing element for the density of the associated friction connection arrangement is outside this force flow. In this way, the sealing element is excluded from the surface pressure of the connecting element against the rim base and is decoupled by the relative movements of the mechanical connection between the connecting arrangement, the rim base and the wheel centers during wheel operation. vehicle.
    [0018] Thus, the material of the sealing element is protected against manifestations of creep and wear under a mechanical load of the connection arrangement driven by friction. The sealing element continuously maintains its sealing effect.
    [0019] The wheel rim of the vehicle must withstand excessive pressure in the tire chamber of up to 8 bar. Consequently, there are high demands on the air density of the wheel base made of fiber composite material and the connection introduced in the wheel base, which are fulfilled, in the best possible way, with the dimensionally stable configuration and independent arrangement according to the invention of the coated sealing element at the rim base.
    [0020] With the arrangement and configuration according to the invention of the sealing element, an additional self-sealing effect of the connection arrangement is obtained. The more pressure that arises from the pressurized tire chamber of the rim, the better the pressure of the sealing element against the rim base and consequently its sealing effect.
    [0021] Also in the case of undue load, which implies damage to the connecting element and other parts of the connection arrangement or a rupture of the spoke parts of the wheel disk, the sealing effect is maintained. In this way, the risk of an accident due to the sudden drop in pressure in the connection arrangement is largely eliminated.
    [0022] As a result, a specifically reliable and safe operating connection arrangement with a fully functional seal is obtained.
    [0023] The objective is still solved, according to the invention, by the fact that the rim has at least one connection arrangement with at least one connecting element, as well as a flexible plastic sealing layer, preferably viscoelastic. , which integrally covers part of one or more adjacent connecting arrangements, extended by the outer side of the rim of the rim of the rim, and a marginal area of the flexible sealing layer is hermetically connected to the rim of the rim.
    [0024] The flexible sealing layer is a rubber-type layer with a different layer thickness of elastic material, preferably viscoelastic plastic, for example, in the form of a thick enameled layer, applied at least partially in the area of the part of the connection arrangement extended to the outer side of the rim of the rim of the rim and covering that part integrally. A marginal area of the flexible sealing layer overlaps the part of the connection arrangement extended by the outer side of the rim base and is connected to the adjacent rim base with a sealing effect.
    [0025] The flexible sealing layer can also collectively cover several parts of the grouped connection arrangements extended by the outer side of the rim and seal them together, offering considerable technological facilitations and impermeable areas for a specifically secure seal.
    [0026] This configuration of the invention can be produced with ease and is suitable, in particular, for wheel constructions with a small manifestation of micro movements in the connection arrangement, which can be well assimilated and compensated by the rubber-type layer.
    [0027] The advantages described above are also associated with this solution and a specifically reliable and safe operating connection arrangement with a fully functional seal can be obtained.
    [0028] Advantageous configurations and improvements of the invention can be deduced from the related claims of the invention, the subsequent description and the respective drawings.
    [0029] An advantageous design provides that the margin of the sealing element or the marginal area of the flexible sealing layer is adhered to a sealing layer of the rim base, preferably of viscoelastic plastic. The sealing element or the flexible sealing layer is associated, in a marginal area around the part of the connection arrangement extended to the outer side of the rim of the rim of the rim, with an adherent and impermeable seal layer of the rim of the rim, which is often applied to the outer rim of the fiber composite wheel base to increase the density of the fiber composite wheel base. Adhesion of the marginal area of the sealing element or the flexible sealing layer can be carried out by overlapping or directly on the rim base, and in this case too, the sealing is uncoupled by the connection arrangement under a mechanical load, as well as guaranteed a safe and stable sealing effect.
    [0030] Another advantageous embodiment is that the sealing element or the flexible sealing layer is covered entirely with a sealing layer of the rim base, preferably of viscoelastic plastic.
    [0031] In this context, it is not necessary to explicitly adhere the sealing elements or the flexible sealing layers in the marginal area around the part of the connection arrangement extended to the outer side of the rim with the rim base. The sealing elements or partially applied flexible sealing layers are fixed using the hermetic sealing layer provided on the outer rim of the rim of the rim and are simultaneously protected against the rim of the rim, with a closed flat impermeable surface being developed over the entire rim. the rim of the rim. The sealing layer, preferably made of viscoelastic plastic, has particularly good adhesion and sealing properties and is therefore very suitable for adhesion in the marginal area of the sealing element or the flexible sealing layer. This configuration avoids the production phase of the impermeable adhesions separated from the individual sealing elements or the flexible sealing layers with the base of the window.
    [0032] Advantageously, the flexible sealing layer is simultaneously a sealing layer of the rim base. In this configuration, the flexible sealing layer on the connection arrangement is integrated, favorably in terms of production and costs, with the sealing layer often provided on the outer side of the rim of the fiber composite wheel base. The sealing paint used can be projected partially in the area of the part of the connection arrangement extended to the outer side of the rim of the rim of the rim with a correspondingly different layer thickness, and must have specifically viscoelastic properties and, therefore, also quite suitable as a sealing layer. flexible.
    [0033] According to a specifically advantageous configuration, the connection arrangement has at least one bushing, into which the connection element is inserted. Using a bushing, preferably metallic or ceramic, which comprises at least partially the passage through the rim of fiber composite material, the vibration friction wear between the connecting element and the fibrous structure of the rim base is permanently reduced , as well as the safety of the connection operation.
    [0034] In this sense, the invention considers that, in the connection arrangements introduced at the base of the rim according to the latest technology, it is specifically problematic to use bushings due to the quality assurance of density. In this way, the pressure density between the moved parts, for example, the bushings and the connecting element, as well as against the rim base, must be produced in a very complicated and expensive way. These necessary multiple seals have already prevented the rim wheel from being connected to the wheel disk using bushings systems for reasons of expense. There is also a high incidence of disturbances of the necessary multiple seals, especially when several connections are usually provided for fixing the wheel disk.
    [0035] The arrangement and execution of the sealing element or the flexible sealing layer according to the invention eliminates these problems with the connection arrangement. With the sealing element superimposed entirely on the connection arrangement on the outer side of the rim or with the flexible sealing layer, an excellent sealing of the connection arrangement, including the bushing (s), is obtained against air pressure of the tire chamber and the rim base, as well as the costly seals of the bushings between them, in relation to the connecting element and the rim base, become unnecessary. However, a stable and fully functional pressure density is obtained for the entire connection arrangement. A secure and cost-effective connection is provided with reduced vibration friction wear and at the same time reliable sealing.
    [0036] Advantageously, an external bushing of the connection arrangement has a plug extended by the external side of the rim.
    [0037] The cap on the outer side of the rim optimizes the introduction of force and the distribution of the surface pressure of the connecting element with the rim of the fiber composite material, thus offering greater protection to the fibrous structure of the rim. dine under a continuous load from the mechanical connection.
    [0038] In this case, the sealing element or the flexible sealing layer is hermetically connected to the rim base in the marginal area around the plug on the outer side of the rim.
    [0039] In this correlation, it is still advantageous when the external bushing or the plug has a corresponding contact surface for the installation of the connecting element or the part of the connecting element extended by the outer side of the rim, providing a specifically good conduction of the element connection and a homogeneous distribution of the forces introduced at the rim base.
    [0040] According to an advantageous configuration of the invention, it is provided that the part of the connecting element extended by the outer side of the rim, for example, the head of the connecting element, and / or the external bushing and / or its plug, is arranged in a groove on the outer side of the rim of the rim base.
    [0041] The fitting can be at least a horizontal flat recess of a curved surface of the outer side of the rim in the area of the part of the connection arrangement extended by the external side of the rim, which provides an improved installation of the parts of the lateral connection arrangement rim of the rim on the surface of the rim base.
    [0042] With a correspondingly designed fitting, it is also possible that the part of the connection arrangement extended by the outer side of the rim is projected with a specifically flat projection on the surface of the outer side of the rim or is precisely aligned with the surface of the outer side of the rim rim or even form a cavity in the surface of the outer side of the window.
    [0043] A built-in installation of the connection arrangement allows the overlapping sealing element to be projected in a broadly flat way, without significant elevation in relation to the external side of the rim, while, however, the concave cover of the connection arrangement part can be preserved. extended by the outer side of the rim. The flat design of the sealing element by the built-in connection arrangement facilitates the mounting of the tire on the rim, in which the tire must be installed on the base of the tire by the outline of the rim base or the outer side of the rim and the sealing elements. This seal configuration reduces geometric impediments when adjusting the tire to the rim base.
    [0044] In another advantageous configuration, the overlapping sealing element is also arranged in a socket on the outer side of the rim of the rim base.
    [0045] The fitting can be at least a flat recess of a curved surface on the outer side of the rim in the area of the edge of the overlapping sealing element, in order to provide a flat installation of the circumferential edge of the sealing element on the rim base. , increasing the security of the density of the sealing element in relation to the rim base.
    [0046] In addition, the fitting can be specially designed so that the sealing element disposed in this way is positioned very flat without significant elevation in relation to the outer side of the rim or, in particular, precisely aligned with the surface of the outer side the rim, the contour of the sealing element accompanying the contour of the rim base.
    [0047] Particularly with the level configuration, all geometric impediments and the formation of cracks between the tire and the rim base can be avoided by adjusting the tire under a pressure load to the rim base.
    [0048] In a specifically advantageous configuration of the invention, it is envisaged that the sealing element is designed in the form of a lid as a flat hermetic lid. The hermetic cap with adjustable dimension offers a corresponding hollow area for the non-contact coverage of the part of the connection arrangement extended by the outer side of the rim of the rim base. The bulging hermetic cover can be easily attached by the part of the connection arrangement extended by the outer side of the rim of the rim of the rim, as well as being marginally adhered to the rim of the rim. This configuration facilitates the production of a safe and stable seal of the connection arrangement. The cap-shaped structure of the sealing element also increases the pressure resistance in relation to the tire pressure prevalent in the adjacent tire chamber.
    [0049] In an advantageous alternative configuration, the sealing element is designed as a substantially flat impermeable disk. With this configuration, it is possible to implement a desired hollow area in the part of the connection arrangement extended by the outer side of the rim by arranging the supporting surface of the rim of the impermeable disc over the part of the connection arrangement extended by the outer side of the rim. This can be done, for example, by generating a corresponding layer height of the impermeable disk margin adherence to the rim base or by arranging, in a recessed form, the part of the connection arrangement extended by the outer rim of the rim at the rim base.
    [0050] The flat formation of the sealing element allows a specifically flat formation of the sealing points, representing another facilitation when adjusting the tire.
    [0051] It is especially advantageous when the airtight cover or waterproof disc is disposed without support. The hermetic cover or the waterproof disc without support is arranged exclusively by its margin and has a natural stiffness that does not deform or undergoes only insignificant deformation during the application of the internal pressure of the rim tire chamber. In this way, on the one hand, an extended seal is guaranteed to the connection arrangement permanently without contact, which is fully decoupled by the micro movements of the connection element and other parts of the connection, for example, the bushing. On the other hand, a support without deformation of the rim of the airtight cover or impermeable disc is guaranteed without support at the rim base, ensuring the density of the airtight cover or impermeable disc in relation to the rim base.
    [0052] A constructively favorable configuration provides that the hermetic cover or the impermeable disk has a reticulated structure for support in the part of the connection arrangement extended to the external side of the window.
    [0053] In this configuration, the hermetic cover or the impermeable disc can be supported, for example, on the bushing, on the bushing plug and / or on the connection element of the connection arrangement. The reticulated support structure makes it possible to design the hermetic lid or the impermeable disk with thin walls, contributing to weight savings.
    [0054] According to another favorable implementation, a flexible support structure is provided to support the airtight cover or the impermeable disc in the part of the connection arrangement extended to the outer side of the rim. The flexible support structure consists of a flexible rubber-like material, preferably based on polyurethane.
    [0055] The hermetic cover or impermeable disc is disposed loose on the flexible support structure, which is fixed or adhered to the part of the connection arrangement extended to the outer side of the rim. This execution also allows to design the airtight lid or the impermeable disk with thin walls and, consequently, with reduced volume.
    [0056] If the support structure is specially arranged in the central region, the best possible load or pressure distribution is obtained over the area of the hermetic cover or the impermeable disc, optimizing the minimization of the thickness of its walls.
    [0057] In a specifically flat configuration of the support structure and / or an arrangement of the support structure in the deep tool gear of the connection element head, an installation or arrangement of the airtight cover or the broadly impermeable disc is permitted, which offers the advantages described above when assembling the tire.
    [0058] In addition, for support, the airtight cover or the impermeable disc has a flexible filling layer on one side facing the outer side of the rim.
    [0059] If the filler layer fills the hollow area formed in the part of the connection arrangement on the outer side of the rim below the airtight cover or impermeable disc, flexible support will appear over the entire length of the airtight cover or impermeable disc on the part of the connection arrangement extended on the outer side of the rim. The filler layer can be designed as an inner lining of the airtight cover or waterproof disc or as an independent filler layer between the airtight cover or waterproof disc and the part of the connection arrangement extended to the outer rim of the rim of the rim base. Preferably, a soft elastic glue is used which ensures sufficient decoupling of the airtight cover or impermeable disc by the micro movements of the connection element and other parts of the connection, for example, the bushing. In this configuration, a high stability of the seal is obtained in relation to the internal pressure of the rim tire chamber, allowing a thinner wall configuration of the hermetic cover or the impermeable disc.
    [0060] In another advantageous configuration, it is provided that an internal bushing of the connection arrangement has a plug extended by the inner side of the rim of the rim base.
    [0061] The lower plug of the inner bushing on the inner side of the rim optimizes the introduction of force and the distribution of the surface pressure of the wheel disc against the base of the composite fiber wheel, thus offering greater protection of the fibrous structure from the rim of the rim under the continuous load of the mechanical connection with specially metallic wheel discs. The forces are introduced to the composite fiber structure in the area of the connection arrangement even more extensively.
    [0062] In this correlation, it is also advantageous when this plug has a corresponding connection area for fixing a connection area of the wheel disc, so that the bushing is made available as a resistant friction element with an extensive friction manifestation for the connection of the wheel disc, an element that further protects the wheel base made of fiber composite material in the area of the connection arrangement.
    [0063] Other advantages arise when the plug of the inner bush has a protrusion over the contour of the inner side of the rim of the rim of the rim. Thus, the wheel disc has contact only with the bushing, totally preventing direct wear by vibrating friction between the wheel disc and the rim base in the vehicle's wheel area.
    [0064] A constructively favorable configuration provides that several bushings of a connection arrangement are arranged interdependently. In this way, the passage through the wheel base made of fiber composite material is fully understood by the bushings and the fiber composite material of the wheel base protected during the passage. The interaction of the interdependent bushings also compensates even better for the relative movements of the mechanical connection manifested during the operation of the vehicle wheel. As a result, the wear caused by vibrating friction between the connecting element and the fibrous structure of the rim base is clearly minimized, further improving operational safety, in addition to the guaranteed high density.
    [0065] The interdependent bushings can also generate a comprehensive galvanic shielding of the rim base in relation to the wheel disc and the connecting element, which shield prevents the manifestation of corrosion by contact especially when using metallic wheel discs.
    This and other features deduced from the patent claims, the description of the configuration examples and the drawings can be realized by themselves or in combination as advantageous configurations of the invention, for which protection is claimed.
    [0067] The device according to the invention will be explained in detail in the following configuration examples. The respective drawings show, in a schematic representation:

    [0078] Figure 11 - an isometric representation of the vehicle wheel according to figure 1 with several connection arrangements with two adjacent connecting screws per radius, covered with a waterproof disc or common hermetic cover.
    [0079] Figure 12 - a partial fragmented representation of the vehicle wheel according to figure 1 with several connection arrangements with an individual connection screw and two bushings and an overlapped enamel layer.
    [0080] Figure 1 shows a section of a vehicle wheel with a rim 1 and a star-shaped wheel disc 2 with a stainless steel spoke unit 3. Rim 1 has a rim of carbon fiber-reinforced plastic (CFK) rim 4, specifically reinforced with carbon nanotubes.
    [0081] The wheel disk 2 is fixedly screwed to the rim 1 by means of several connection arrangements 5 provided corresponding to the number of spokes 3, each consisting of a flat head connection screw 6. The flat head connection screws 6 of stainless steel are guided through a through hole 7 in the rim of the rim 4, with a flat head 8 of the connecting screw 6 extending to the outer side of rim 9 of rim 1 and being fixed precisely adjusted to the rim of rim 4 , while a threaded rod 10 of the connecting bolt 6 engages at each of the spoke ends 11 of the wheel disc 2. In the bolted state, the front areas 12 of the spoke ends 11 are arranged on an inner side of the rim 13 of the wheel. rim 1 precisely adjusted to the base on rim 4.
    [0082] To the outer side of rim 9, a tire chamber 14 of rim 1 is connected, shown only partially, which is limited by an unrepresented tire installed on rim 1. In this way, connection arrangement 5 is covered in the state riding the vehicle wheel and is not visible from the outside area.
    [0083] A sealing element 15 in the form of an airtight cap without support 15 fully covers the screw head 8 extended to the outer side of the rim 9, in a concave manner, without having contact with it. On a flanged margin 16, the hermetic cap 15 is hermetically adhered to the rim of the rim 4 by means of a circumferential adhesion 17.
    [0084] The cap 15 in a domed stainless steel shape has sufficient natural stiffness, which guarantees the dimensional stability of the airtight cap 15 also under the predominant tire pressure of the tire chamber 14 to be operated with up to 8 bar, as well as prevents direct contact with the screw head 8.
    [0085] With the airtight cap 15 of natural stability, marginally adhered, the tire chamber 14 is fully protected in relation to the through hole 7 of the rim base 4 and the connecting screw 6 and, consequently, to the external atmosphere.
    [0086] If the connection arrangement is installed in an area of the base of the rim 14 with a curved surface of the outer side of the rim 9, at least and preferably the support surface of the hermetic cover 1 is flattened so that the circumferential margin 16 of the hermetic cover 15 is arranged in the best possible way to the rim base 4. The horizontal flat recess can also extend over the entire overlapping area of the sealing element, in this case, of the hermetic cover 15, so that the part of the arrangement connector 5 extended on or adjacent to the outer side of the rim 9 proceed with a flat installation at the base of the rim 4, as shown in figures 1 to 9.
    [0087] The hermetic cover 15 is outside the surface pressure of the connecting screw 6 driven by friction against the rim base and the wheel disk 2 and is fully decoupled by the relative movements manifested during the operation of the vehicle wheel between the disk wheel 2, connecting screw 6 and rim base 4.
    [0088] The hermetic cap 15 and its grip 17 are not exposed to the mechanical load of the connection arrangement 5 driven by friction and are protected against the manifestations of creep and wear by vibrating friction. In this way, the sealing effect of the connection arrangement is constantly guaranteed.
    [0089] Simultaneously, the rim base 4 specifically reinforced with carbon nanotubes satisfactorily resists mechanical loads in connection arrangement 5, resulting in a reliable and safe operation connection arrangement 5 with a functionally stable seal for the connection from rim 1 to wheel disc 2.
    [0090] In figure 2 is shown a cutout of a vehicle wheel with a rim 1 and a star-shaped 2.1 wheel disk with a radius unit 3.1, associated with each other by means of several connection arrangements 5.1 provided corresponding to the number of rays 3.1. The base of rim 4 of rim 1 consists, according to the configuration example according to figure 1, of CFK, specifically reinforced with carbon nanotubes. The wheel disk 2.1 is made of aluminum.
    [0091] Only the differences in relation to the configuration example according to figure 1 are described below significantly. The same components are provided with the same reference numbers.
    [0092] As another difference in relation to the configuration according to figure 1, the respective connection arrangement 5.1, in addition to the flat head connection screw 6 of stainless steel, consists of a bushing inserted internally 18 of stainless steel, which is arranged, viewed from the inner side of the rim 13, through the through-holes 7 of the rim of the rim 4 and has a plug 19 extended by the inner side of the rim 13 from the rim 1. A stem of the insert bushing 18 is inserted flat into the through-hole 7. The insert bushing 18 partially covers the through hole 7 and surrounds the marginal area at the base of the rim 4 extended to the inner side of the rim 13.
    [0093] The connecting screw 6 is carried out, levelly, through the through hole 7 and the bushing inserted internally 18, with the flat screw head 8 being precisely adjusted to the outer side of rim 9 of rim 1 and the stem thread 10 engages at each end of spoke 11.1 of the wheel disk 2.1.
    [0094] Each cap 19 has a certain wall thickness, by which it extends to the inner hollow area of the rim of rim 1 and has a projection over the inner contour of the rim of the rim 4. In each cap 19 a projection area is projected connection 2 0 for the corresponding individual installation of the front area 12.1 of the spoke ends 11.1 of the wheel disk 2.1. The connection area 20 forms, during the operation of the vehicle wheel, a solid friction element of the front areas 12.1 of the spoke ends 11.1 of the wheel disk 2.1.
    [0095] The micromovements manifested during the operation of the vehicle wheel, in this configuration of the connection arrangement 5.1, do not cause direct wear by vibration friction between the fibrous structure of the rim of the rim 4 and the angled front area 12.1 of the wheel disc of 2.1 aluminum, and cause reduced wear by vibrating friction between the fibrous structure of the rim of the rim 4 and the connecting bolt 6.
    [0096] This is quite advantageous, since the relative movements, due to the elasticity of the aluminum 2.1 wheel disc, are substantially more intense than in a relatively more rigid stainless steel wheel 2 disc as shown in figure 1. With the additional insert sleeve 18, it is possible to further improve the operational safety of the 5.1 connection arrangement.
    [0097] Analogously to the sealing element 15 according to figure 1, the hermetic cover 15 without stainless steel support fully covers the screw head 8 extended to the outer side of the rim 9, without having contact with it in this case. On the flanged edge 16, the hermetic cap 15 is hermetically adhered to the rim of the rim 4 by means of a circumferential adhesion 17.
    [0098] With this hermetic cover 15, the same advantages are realized as in the configuration example according to figure 1. The seals of the bushing 18 against the rim of the wheel 4 and the wheel disk 2.1 are not necessary.
    [0099] Figure 3 shows, as a difference in relation to the configuration according to figure 2, the cutout of a wheel, in which a 1.1 wheel with a 4.1 fiberglass reinforced plastic (GFK) wheel base and a wheel star-shaped wheel 2.1 with an aluminum radius 3.1 unit are linked together by means of various connection arrangements 5.2 in the corresponding number of radii 3.1.
    [00100] In the following, only the differences in relation to the configuration example according to figure 2 are described significantly. The same components are provided with the same reference numbers.
    [00101] The connection arrangement 5.2 individually consists of a recessed head connection screw 21 of steel and an inner sleeve 22 and an outer sleeve 23 of steel, which are inserted by the inner side of the rim 13 or by the outer side of the rim 9 from through hole 7 of the rim base 4.1 and are arranged interdependently. The inner bush 22 has a plug 24 extended by the inner side of the rim 13 of the rim 1.1 similarly to the plug 19 of the insert bush 18 as shown in figure 2, while the outer bush 23 has a plug 25 extended by the outer side of the rim 9 of the rim 1.1.
    [00102] The recessed head connection screw 21 is executed through the through hole 7 with the external and internal bushings 22, 23 inserted, with the conical recessed head 26 of the recessed head connection screw 21 is arranged precisely adjusted to a tapered contact surface 27 of a tapered section of the outer sleeve 23, and the threaded rod 28 engages at each of the spoke ends 11.1 of the wheel disk 2.1.
    [00103] In each cap 24 of the internal bushings 22, which show a projection on the inner contour of the rim of the rim 4.1, a connection area 2 9 is designed for the respective individual arrangement of the front area 12.1 of the spoke ends 11.1 of the disc of the wheel 2.1. The connection area 29 forms - analogously to the connection area 20 of the plug 19 of the insert bushing 18 according to the configuration of figure 2 - a solid friction element of the front areas 12.1 of the spoke ends 11.1 of the wheel disk 2.1, without having contact with the rim of the rim 4.1. Both bushings 22, 23 involve both the entire through hole 7 and the marginal area extended to the outer area of the rim 9 and the inner side of the rim 13.
    [00104] In this configuration of the connection arrangement 5.2, the micro movements manifested during the operation of the vehicle wheel do not cause direct wear due to vibration friction between the fibrous structure of the rim of the rim 4.1, the built-in head connection screw 21 and the disc of the wheel 2.1. Connection arrangement 5.2 protects, in particular, the wheel base 4.1 of relatively soft GFK.
    [00105] The interdependent arrangement of bushings 22, 23 can also compensate for the relative moments in the inner area of the connection arrangement 5.2 and continue to reduce wear by vibrating friction.
    [00106] This is quite advantageous, since the relative movements, as a result of the elasticity of the aluminum 2.1 wheel wheel, are significantly more intense than in a relatively more rigid stainless steel wheel wheel 2 as shown in figure 1.
    [00107] Using the bushing system with two interdependent bushes 22, 23, the operational safety of the connection arrangement 5.2 is further improved.
    [00108] The reliable density of the connection arrangement 5.2 is obtained with an airtight cover 30 of steel of natural stability without support, which fully covers the screw head 26 of the recessed head connection screw 21 and the plug 25 of the external bushing 23 , without having contact with those parts of the connection arrangement 5.2. A flanged edge 31 of the hermetic cap 30 is disposed at the base of the rim 4.1 in the marginal area around the outer plug 23 extended to the outer side of the rim 9 and hermetically adhered to the base of the rim 4.1 by means of a circumferential adhesion 17.
    [00109] Preferably, the overlapping hermetic lid area 30 has a flat recess of the curved surface of the outer side of the rim 9, through which the part of the connecting arrangement 5.2 extended to the outer side of the rim 9 and the circumferential edge 31 of the lid hermetic 30 are arranged as best as possible on the rim of the rim 4.
    [00110] In this way, an excellent seal of the connection arrangement 5.2 is obtained against the air pressure of the tire chamber 14, and, due to the external position and dimensionally stable structure of the hermetic cap 30, the sealing effect is maintained continuously connection arrangement 5.2.
    [00111] In addition to improving the operational safety of the connection arrangement 5.2 with the bushing system 22, 23, the same advantages regarding the sealing effect as shown in the configuration examples in figures 1 and 2, are realized with this hermetic cover 30 The seals of the bushings 22, 23 are not necessary between each other and against the rim of the rim 4.1 and the wheel disk 2.1.
    [00112] Figure 4 shows, analogously to the representation of figure 3, a cutout of a wheel, in which a rim 1.1 with a rim of GFK rim 4.1 and a star-shaped wheel 2.1 with a radius unit 3.1 of aluminum are connected to each other by means of connection devices 5.2 as shown in figure 3.
    [00113] In the following, only the differences in relation to the configuration example according to figure 3 are described significantly. The same components are provided with the same reference numbers.
    [00114] Diverging from the execution of figure 3, the rim of the rim 4.1 has a viscoelastic enameled layer 32, applied to the outer side of rim 9 of the rim of the rim 4.1 to increase the air density of the composite fiber material of the rim of the rim 4.1 . The enamelled layer 32 can be formed, for example, with a spray paint with granules of viscoelastic plastic. The enamelled layer 32 of viscoelastic plastic individually wraps the plug 25 of the external bushing 23 of the connection arrangement 5.2 extended to the external side of the rim 9. The airtight cover 30 of steel, with natural stability and without support, which fully covers the screw head 26 of the recessed head connection screw 21 and the plug 25, is fixed on the viscoelastic enameled layer 32 and its margin 32 hermetically adhered to the enameled layer 32 in the marginal area around the plug 25. The enameled layer 32, which is normally used to seal the rim of the rim 4.1, it is well suited as an elastic sealing and adhesion agent for fixing and airtight adhesion of the hermetic lids 30. Adhesion with a separate binder is not necessary.
    [00115] Hermetic lids 30 adhered to the enameled layer 32 complete the hermetic sealing of the rim of the rim 4.1, the enameled layer 32 being unnecessary in the inner area of the hermetic lid 30. The plug 25 of the external bushing 23 can be directly supported at the rim of the rim 4.1. The enamelled layer 32 is not arranged in the force flow of the connection arrangement 5.2, so that a disadvantageous creep of the enamelled layer 32 is excluded due to the micromovements of the bushing 23.
    [00116] It is possible to observe in figure 5, analogously to the representation according to figure 4, the rim 1.1 with a rim of the rim 4.1 of GFK and the wheel disk 2.1 in star shape with a radius unit 3 of aluminum, which are connected to each other by means of connection arrangements 5.2 according to figure 3. The base of the rim 4.1 is coated with the viscoelastic enameled layer 32 to increase the air density of the fiber composite material on the outer side of the rim 9.
    [00117] In the following, substantially only the differences in relation to the configuration example in figure 4 are described. The same components are provided with the same reference numbers.
    [00118] Different from the configuration according to figure 4, the enameled layer 32 of viscoelastic plastic, which serves for the usual sealing of the rim of the rim 4.1, is designed consistently on the rim of the rim 4.1, with the hermetic caps 30 of steel without support, affixed to the rim of the rim 4.1, are coated with the enameled layer 32 and hermetically adhered to the enameled layer 32, simultaneously, on the flanged edge 31.
    [00119] With this configuration, it is possible, in addition to the advantages described above, to obtain an airtight seal of closed surface outside the connection arrangement 5.2 with minimization of production costs, since the hermetic adhesions of the hermetic covers 30 can be carried out simultaneously with the production process of the rim base coating 4.1.
    [00120] In the configuration example as shown in figure 6, a cutout of a vehicle wheel is shown, which has a rim 1.2 with a base of rim 4.2 of CFK and the wheel disk 2.1 in the form of a star with the radius unit 3.1 made of aluminum, connected to each other by means of connection provisions 5.2 as shown in figure 3.
    [00121] Different from the previously described configurations, the sealing element 33 is an airtight plastic cap 33 for sealing the connection arrangement 5.2, which fully covers the screw head 26 of the recessed head connection screw 21 and the external plug 25 from the external bushing 23 extended to the external side of the rim 9. The concave airtight cover 33 has a reticulated structure 34 for support in relation to the plug 25, however, without having contact with the built-in head 26.
    [00122] A flanged margin 35 of the hermetic cap 33 is arranged at the rim base 4.2 in the marginal area around the cap 25 and is hermetically adhered to the rim base 4.2 by means of a circumferential adhesion 17, in order to seal the arrangement of connection 5.2 against the tire chamber.
    [00123] The reticulated structure 34 gives the airtight lid 33 of relatively designed plastic with thin walls sufficient dimensional stability, so that the airtight lid 33 does not deform under the predominant tire pressure of the tire chamber 14 on rim 1.2 and, consequently , an impermeable connection of the hermetic cover 33 on the rim of the rim 4.2 is continuously guaranteed on one side and, on the other side, direct contact with the flush head 26 is avoided.
    [00124] The reticulated structure 34 is supported on the loose and floating support in relation to the plug 25, so that the external bushing 23 can move freely with the micro movements during the operation of the vehicle wheel and the transfer of oscillations to is largely uncoupled the airtight lid 33.
    [00125] This configuration is suitable, in particular, for wheel constructions with greater rigidity, for example, as they are used in sports vehicles. In these wheel constructions, relative movements in the connection arrangement are manifested to a lesser extent as a result of a more rigid rim and / or a more rigid wheel disc, making the effects on hermetic covers 33 in contact correspondingly insignificant. with loose bushings. In the present configuration example, the aluminum wheel disk 2.1 is combined with a rigidly conditioned rim 1.2, the base of the CFK rim 4.2 of which has a large wall thickness and / or the CFK has a high density of fibers and / or fibers high modulus of high rigidity.
    [00126] This configuration of the hermetic lid 33 with reticulated structure 34 allows to minimize the wall thickness and the weight of the hermetic covers 33, implying a volume saving in the construction of the wheel, of specific importance for sports vehicles.
    [00127] Figure 7 shows a cutout of a vehicle wheel, which presents, similarly to the configuration example in Figure 6, a 1.2 rim with a CFK rim base 4.2 and a 2.1 star-shaped wheel disc with a radius unit 3.1 of aluminum, connected between by means of connection provisions 5.2 according to the configuration of figure 3.
    [00128] In the following, only the differences in relation to the configuration according to figure 6 are described significantly. The same components are provided with the same reference numbers.
    [00129] Different from the sealing of the connection arrangement 5.2 according to figure 6, the sealing element 36 is an airtight cover 36 of plastic specifically with thin walls with a coating on the inner side of a filling layer 37. The airtight cover 36 of thin walls integrally cover the screw head 26 of the recessed head connection screw 21 and the plug 25 of the external bushing 23 extended to the external side of the rim 9, forming a hollow area.
    [00130] The airtight plastic cover 36 with thin walls is coated on the inner side, consequently facing the outer side of rim 9, with a filling layer 37 of a soft elastic filler glue, and, in the assembled state, the filling layer 37 fills the hollow area of the connection arrangement 5.2 and is disposed adjacent to the screw head 26 and the plug 25.
    [00131] Alternatively, it is possible, in place of the coating, to dispose of a separate filling layer or a filling structure of a soft elastic plastic in the hollow area between the screw head 26 and / or the plug 25 and airtight cover 36.
    [00132] The flanged edge 38 of the hermetic cover 36, preferably uncoated, is arranged at the rim of the rim 4.2 in the marginal area around the plug 25 and is hermetically adhered to the rim of the rim 4.2 by means of a fixed circumferential grip 17, in order to produce the seal of the connection arrangement 5.2 against the tire chamber.
    [00133] The liner 37 of the hermetic cap 33 or the filling layer / filler structure 37 at regular intervals protects, on the one hand, the hermetic cap 36 from the tire pressure of the tire chamber 14, and it is possible to further reduce, with this configuration, the thickness of the walls and the weight of the hermetic lids 36 favor a light wheel construction.
    [00134] The liner 37 of the hermetic lid 33 or the filling layer / filling structure 37 at regular intervals, on the other hand, produces a floating support on the screw head 26 and the plug 25, so that the connecting screw with built-in head 21 and external bushing 23 can move freely with the micro movements during the operation of the tire wheel. The oscillations are largely decoupled by the soft elastic filling layer 37 and transferred to the hermetic lid 36 only in an insignificant proportion.
    [00135] This configuration is also suitable for wheel constructions with greater rigidity, as used in sports vehicles. In the present configuration example, as well as in the configuration example according to figure 6, the aluminum wheel disk 2.1 is combined with a rigidly conditioned rim 1.2, the base of the CFK rim 4.2 of which has a large wall thickness and / or the CFK has a high density of fibers and / or high modulus fibers with high rigidity. The relative movements in the connection arrangement manifested to a lesser extent in these wheel constructions act insignificantly small on the hermetically protected covers 36 which are flexibly protected.
    [00136] The configuration example according to figure 8 also refers to a relatively rigid wheel construction corresponding to figures 6 and 7. Figure 8 shows a cutout of a vehicle wheel, which has a 1.2 rim with a base of rim 4.2 with large wall thickness of CFK and a wheel disc 2 in the shape of a stainless steel star, similarly to the configuration according to figure 1.
    [00137] Differing from the configurations according to figures 6 and 7, the rim 1.2 and the wheel disk 2 are associated with each other by means of several connection arrangements 5.3 in corresponding quantity of spokes 3, which consist of the recessed head connection screw 21 and an external insert bushing 39.
    [00138] This execution of the bushing is suitable, among others, for the use cases in which, according to the technology of the materials, the direct contact of the wheel disc with the rim base is not problematic. The simple, unique and low-volume configuration offers, in addition to weight savings, a lower production and assembly expense, and thus improves the lightweight structure of the wheel construction at reduced costs.
    [00139] The external insert bushing 39 is inserted, seen from the outer side of the rim 9, into the through hole 7 of the rim of the rim 4.2 and completely covers the through hole 7 significantly. A conical section of the external insert sleeve is placed in a correspondingly notched groove in the rim of the rim 4.2.
    [00140] The external insert bushing 39 has a plug 40 extended by the outer side of the rim 9.
    [00141] The screw head 26 of the recessed head connection screw 21 is disposed, in the assembled state, flat on the contact surface of the conical section of the external insert bushing 39.
    [00142] The conical section and the plug 40 of the external insert bushing 39 meet the best distribution of the surface pressure in the connection arrangement 5.3 during the operation of the tire wheel.
    [00143] To seal the connection arrangement 5.3, the airtight thin-walled plastic cover 36 covers the screw head 26 of the recessed head connection screw 21 and the plug 40 of the external insert bushing 39 extended to the outer side of the rim 9, this forming a hollow area over the part of the connection arrangement 5.3 extended by the outer side of the rim. In the marginal area around the cap 40, the margin 38 of the hermetic cap 36 is hermetically adhered to the rim of the rim 4.2 by means of a circumferential grip 17. The grip 17 can be fixed on the outer side of the rim 9 or on a flat undercut of the rim. curved surface of the outer side of the rim 9 of the rim of the rim 4.2, preferably provided in the area of the hermetic cover 36, allowing the part of the connection arrangement 5.3 extended to the outer side of the rim 9 and the circumferential margin 38 of the cover hermetic 36 are positioned at the base of rim 4.2 in the best possible way.
    [00144] Figure 8 shows an alternative configuration of the concave lid support 36 concave, provided, in this case, by a flexible support structure 41, which supports the airtight cover 36 in relation to the screw head 26 of the head connection screw flush 21. The flexible support structure 41 of elastic rubber-like material based on polyurethane is produced separately and is inserted into the screw head 26 before mounting the airtight cover 36 in the hollow area of the tool gear or adhered with a flexible glue.
    [00145] The concave hermetic cover 36 is loosely arranged on the flexible support structure 41. The support structure 41 arranged in the central area supports the hermetic cover 36 in the central part, and a better load or pressure distribution can be obtained and consequently the wall thickness of the hermetic lid 36 is further optimized.
    [00146] The hermetic cover 36 is largely detached from the support structure 41 and the screw head 26 through its loose and floating support. Due to the loose support and the elastic consistency of the support structure 41, the micro movements of the connection arrangement 5.3 are transferred to the hermetic cover 36 only in an insignificantly small proportion. In any case, there are insignificant frictional manifestations between the screw head 26 and the support structure 41, as well as between the support structure 41 and the airtight cover 36.
    [00147] The support structure 41 disposed deep in the hollow area of the screw head 2 6 allows a wide flat execution of the airtight cover 3 6 with a small overrun by the rim base contour 4.2.
    [00148] In addition, it is also possible, for a flat execution of the seal, to insert the plug 40 of the external insert bushing 39 in a flat fit of the outer side of the rim 9 of the rim of the rim 4.2 (not shown). The grip 17 for sealing the airtight cover 36 can also be fixed in depth in this flat fitting (not shown in this case) of the outer side of the rim 9, further reducing the overlap of the airtight cover 36 by the outline of the rim of the rim 4.2.
    [00149] The structure and flat arrangement of the hermetic cover 36 makes it easier to install the tire on the rim, in which the tire must slide to the base of the tire along the contour of the rim base by the shoulder of the deep base. In their flat configuration, the seals represent a much less impediment during installation.
    [00150] This configuration of the hermetic cover 36 supported by the support structure is also suitable for the constructions of the wheel with greater rigidity, as they are used, for example, in sports vehicles, since, in these constructions of the wheel, the relative movements manifested to a lesser extent in the connection arrangement they act in an insignificantly small way on the hermetic plugs 36 of flexible support.
    [00151] In figure 9, a cutout of a vehicle wheel is shown, which features a 1.1 rim with a GFK rim 4.1 base and a star-shaped wheel disc 2 with a stainless steel radius unit 3 similarly to the configuration according to figure 1, which are associated with each other by means of various connection arrangements 5.4 in corresponding quantity of radii 3.
    [00152] The connection provisions 5.4 are individually composed of the recessed head connection screw 21 and an external insertion sleeve 42 in the form of a funnel with a distinct conical section, which deals with the surface pressure without a plug.
    [00153] The funnel-shaped external insert bushing 42 is arranged in the through hole 7 of the rim of the rim 4.1 and inserted into a correspondingly notched groove of the rim of the rim 4.1 so that the outer lateral edge of the rim of the insert bush 42 in the form of a funnel ends up fitting the surface of the outer side of the rim 9 or a surface of the flat recess of the outer side of the rim 9 of the rim of the rim 4.1.
    [00154] The screw head 26 of the recessed head connection screw 21 screwed into the insert sleeve 42 is aligned with the outer lateral rim of the insert sleeve 42 in a funnel shape or shape, as shown in figure 9, preferably a cavity in relation to the outer lateral rim of the insert bush 42.
    [00155] In this way, the part of the connection arrangement 5.4 extended by the outer side of the rim permanently dispenses with a projection on the surface of the outer side of the rim 9, making it possible to design a specifically flat overlap seal.
    [00156] The conical section distinct from the insert sleeve 42 provides an especially good transfer of the surface pressure in the connection arrangement 5.4 in relation to the rim of the rim 4.1 during the operation of the vehicle wheel.
    [00157] In addition, this insert bushing 42 should be produced more easily than a bushing with a plug.
    [00158] Another advantage arises from a built-in arrangement of connection arrangement 5.4 in the rim of the rim 4.1 according to figure 10, since the tapered fitting to be provided for the funnel-shaped insert 42 can be widely designed homogeneously and should be developed, in particular, without a separate fitting for a plug.
    [00159] In order to seal the connection arrangement 5.4 according to figure 9, an impermeable disc 43 is provided, planed flat without support of thin-walled steel plate, which stretches the screw head 26 of the connection screw too much, in a concave arrangement. with recessed head 21 and the outer lateral rim of the insert bushing rim 42, without having contact with these parts.
    [00160] The waterproof disc without support 43 of sheet steel has a sufficient natural stiffness to preserve the pressure manifested in the chamber of the adjacent tire 14 and not to deform.
    [00161] In the marginal area around the funnel-shaped insertion sleeve 42, a circumferential margin 44 of the impermeable disc 43 is hermetically adhered to the rim of the rim 4.1 by means of an adhesion 17. The adhesion 17 can be fixed to the outer side of rim 9 or the flat recess of the outer side of rim 9 of the rim of the rim 4.1.
    [00162] With the aid of a minimum layer height of the adhesion 17, as shown in figure 9, the impermeable disc 43 flat without support can extend concave through the part of the connection arrangement 5.4 of the outer side of the rim, levelly arranged - without having direct contact with the part of the connection arrangement 5.4 on the outer side of the rim.
    [00163] In the combination of the level arrangement of the part of the connection arrangement 5.4 on the outer side of the rim and the flat geometry of the impermeable disc 43, it is possible to design the overlapping seal of the connection arrangement 5.4 even more flat. The overtaking of the seal by the surface of the outer side of the rim 9 of the rim of the rim 4.1 is markedly less accentuated, facilitating the assembly of the tire around another. Mechanical impediments to tire installation along the rim rim 4.1 are largely minimized. The cracks between the rim of the rim 4.1 and the rim of the tire resulting from the high points of the seal are significantly reduced, through which the unwanted air can escape from the inner area of the tire 14 during the installation of the tire with the application of pressure.
    [00164] The waterproof flat disc 43 can also be easily produced.
    [00165] Differing from the configuration of figure 9, in the configuration according to figure 10, a flat recess is provided for the flat connection of the funnel-shaped insert 42 and for the circumferential flat installation of the disk margin 44 waterproof 43 on the outer side of the rim 9, a flat fit of the outer side of the rim 9 of the rim of the rim 4.1, on which, on one side, the outer bushing 42 ends in the form of a funnel, and on which, on the other, flat waterproof disc 43 is built-in.
    [00166] As shown in figure 10, the fitting is designed so that the impermeable disc 43 embedded in the marginal adhesion 17 preserves a hollow area in relation to the covered part of the connection arrangement 5.4, as well as being precisely aligned with the surface of the external side of rim 9, making it possible for the outer contour of the impermeable disc 43 to follow the rim contour broadly and properly.
    [00167] In this configuration, no edges or overtaking are manifested by the rim base contour 4.1, and installation impediments during tire assembly, as well as an unwanted pressure loss as a result of the sealing points, can be totally excluded.
    [00168] Figure 11 shows a vehicle wheel according to the invention, which presents, corresponding to the configuration examples described above, an optional rim 1, 1.1 or 1.2, with a rim base 4, 4.1 or 4.2 and a disc of the optional star-shaped wheel 2 or 2.1 with a radius unit 3 or 3.1, which are associated with several optional connection arrangements 5, 5.1, 5.2, 5.3 or 5.4.
    [00169] In special wheel configurations, for example, in the case of a vehicle wheel with a spoke unit with a small amount of spokes or specifically wide spokes, as shown, it can be favorable, to ensure a better transfer of force from the disk from wheel 2 or 2.1 to rim base 4, 4.1 or 4.2, carry out various connection arrangements 5, 5.1, 5.2, 5.3 or 5.4 grouped in the gear in a radius.
    [00170] In this configuration example, for the connection of the wheel disk 2, 2.1 to the rim of the rim 4, 4.1, 4.2, two of the connection arrangements 5, 5.1, 5.2, 5.3 or 5.4 are arranged very close together and engage in one and the same radius 3 or 3.1. In this way, a double number of connection arrangements 5, 5.1, 5.2, 5.3 or 5.4 is provided with reference to the number of rays 3.
    [00171] The connection provisions 5, 5.1, 5.2, 5.3 or 5.4, arranged adjacent and individually in groups of two, are covered together by an airtight cover 45 or impermeable disc 45 ’designed flat and extended in an oval direction.
    [00172] The hermetic cover 45 or 45 'oval waterproof disc totally covers, in a concave shape, the parts of the connection arrangements 5, 5.1, 5.2, 5.3 or 5.4 extended by the outer side of the rim 9 and hermetically adhered to the rim of the rim 4 , 4.1, 4.2 in the circumferential marginal area of connection provisions 5, 5.1, 5.2, 5.3 or 5.4 individually grouped by means of circumferential adhesion 17.
    [00173] A flat recess in the outer side of the rim 9 in a curved direction extends over the entire area of the hermetic cover 45 or waterproof disc 45 'oval superimposed so that, in addition to the parts of the connection arrangement 5, 5.1, 5.2, 5.3 or 5.4 extended by the outer side of the rim, the hermetic cover 45 or waterproof disc 45 'oval is also laid flat on the rim of the rim 4, 4.1, 4.2 and seals the connection arrangement 5, 5.1, 5.2, 5.3 or 5.4 appropriately against the rim of wheel 4, 4.1, 4.2.
    [00174] The hermetic lid 45 or the waterproof disc 45 'oval superimposed on various connection arrangements generates, in the case of a small construction area, a sufficiently large sealing surface with the sealing advantages described previously.
    [00175] This configuration of the seal also implies a small amount of overtaking by the surface of the rim of the rim 4, 4.1, 4.2 or a small amount of support cracks between the tire wheel of the tire to be installed and the surface of the base rim 4, 4.1, 4.2, also facilitating the tire assembly.
    [00176] A record of a vehicle wheel is shown in figure 12, which features a 1.2 rim with a CFK rim base 4.2 and a star-shaped wheel disc 2 with a steel radius unit 3 stainless steel similar to the configuration according to figure 1, which are connected to each other using connection arrangements 5.2 similarly to the configuration according to figure 3.
    [00177] The screw head 26 of the recessed head connection screw 21 and the plug 2 5 of the external bushing 23 are coated with a flexible sealing layer 46, corresponding to the enameled layer 32 of the same configuration example, which is designed on the outer side of rim 9 of rim 1.2 to increase the air density of the fiber composite material of the rim of the rim 4.2. The sealing layer 46 or the enamelled layer 32 is applied continuously on the outer side of rim 9 of the rim of the rim 4.2 and on the parts of the connection arrangement 5.2 extended to the outer side of rim 9, at the same time being covered the parts of connection arrangement 5.2 extended to the outer side of the rim 9.
    [00178] The sealing layer 46 or the enamelled layer 32 is designed, preferably thicker, in the area of the parts of the connection arrangement 5.2 extended to the outer side of the rim 9.
    [00179] In this way, a rubber-type viscoelastic sealing layer is formed, which not only completely seals the parts of the connection arrangement 5.2 extended to the outer side of the rim 9 against the air pressure of the tire chamber 14, but also assimilates and compensates well for the micro movements of the connection arrangement 5.2, manifested during the operation of the vehicle wheel, without impairing the sealing effect in any aspect.
    [00180] With this configuration, in addition to the advantageous sealing effect described above, a minimization of production costs can be obtained, since separate sealing elements are not required for sealing connection arrangements 5.2 arranged individually or in groups, the formation of the flexible seal layer 46 can be carried out at once with the seal 32 of the rim base 4.2.
    [00181] This configuration is particularly suitable for heavy wheel constructions with high rigidity. In these wheel constructions, there are, in a specifically smaller proportion, micromovements in the connection arrangement as a result of a rigidly designed rim and a more rigid wheel disc, the effects on the overlapping flexible sealing layer 46 being correspondingly minor. , as well as assimilated by it.
    [00182] In the present configuration example, the stainless steel wheel disc 2, made up relatively rigid and heavy, is combined with a heavy configuration of the rim 1.2, whose base of the rim CFK 4.2 has a large wall thickness and / or the CFK has a high fiber density and / or high modulus fibers of specifically high stiffness.
    [00183] In an example not shown, the flexible seal layer 46 can also cover a connection arrangement 5, 5.1, 5.3 or 5.4. The flexible sealing layer 46 can also be, in this case, the same as the enamelled layer 32, projected on the outer side of the rim 9 to increase the air density of the fiber composite material of the rim of the rim 4, 4.2.
    [00184] This configuration is also suitable for especially heavy wheel constructions with high rigidity, as previously described, and for wheel constructions, whose rims 1 have simultaneously a wheel base 4 with fiber composite material developed with little wear analogously to the base of rim 4 as shown in figure 1.
