    [001] Description
    [002] The present invention relates to a brake disc mounted on a shaft having a hub, in which two friction rings are arranged parallel and spaced from each other.
    [003] Shaft-mounted brake discs are employed in particular in railway vehicles, and through the constructed shape of the shaft-mounted brake discs, these can be assembled from multiple individual components.
    [004] Shaft-mounted brake disc is to mean a shaft-mounted brake disc which is assembled with at least two components. Here, a shaft-mounted brake disc is to be described, in particular a brake disc which has two friction rings which are not formed in one piece and structure uniformly with each other, for example, as it is known in a casting method, but which are supplied individually and preferably mounted on a pair of friction rings by other elements. As a more individual part, the hub in this case can be joined to the pair of friction rings in the assembly.
    [005] For example, shaft brake discs having a hub, in which two friction rings are connected parallel and spaced from each other, are known. Between the friction rings, support screws can extend, which are arranged to absorb contact pressure forces from the axially acting inserts. In particular, in the case of heavy rail transport vehicles, the pad contact pressure forces that are applied to the pair of friction rings by the brake coupling through the brake pads can reach very high values. From this arises the requirement to incorporate brake discs on shafts with support bolts arranged between the friction rings in a sufficiently rigid and mechanically highly loadable manner.
    [006] In addition to this, heat removal is necessary and it is often provided that an air flow is generated that flows axially over the brake disc on shaft, for example, on the side of the hub and flows out radially on the side. out. By means of this air transfer the brake disc can be cooled through heat convection and the air flow is generated through the rotation of the brake disc on its axis. In particular in the case of molded shaft brake discs, geometric figures molded between the friction rings are known which simulate the geometry of a radial fan, so that the corresponding air transfer through the shaft brake disc is obtained.
    [007] Substantially two types of ventilation are distinguished, the described radial ventilation type and a tangential ventilation type. If an axle-brake disc has support bolts between the friction rings, these cause very tangential ventilation. By rotating the brake disc on the shaft, the surface of the bearing screws is subjected to an incident tangential flow, as a result of this, the heat is discharged by convection. Here, the effect can be seen that the flow medium likewise flows slightly from the inner diameter to the outer diameter, as is also the case with the radial fan. However, this effect plays only a minor role for substantially an axial airflow is obtained. What is important here is an optimal arrangement and sizing of the support screws so that the greatest heat dissipation is achieved.
    [008] In particular, shaft-mounted brake discs are known as ceramic brake discs, which comprise friction rings of a ceramic material, generally, however, of a material from the carbon group. Often the hub of such non-metallic brake discs is produced from a steel material, and elaborate connection geometries are necessary in order to avoid heat-induced distortions between the ceramic or carbon material and the metal hub to receive the rings. of friction.
    [009] State of the art
    [010] From DE 195 07 922 C2 a shaft-mounted brake disc is known, which is composed of two friction rings that are arranged parallel and spaced apart in a hub, whose friction rings can be extracted from a plate by means of flame in a simple way. Between the friction rings is located a fan insert, which serves to improve the cooling inside the friction rings. In order to receive the axially acting pad contact pressure forces for the locking operation, the fan insert shown, however, is inadequate and the axial forces that are generated through the brake caliper by the brake pads to the rings friction has to be absorbed by connecting the friction rings to the hub. For this reason, a design of an on-axis brake disc that has a much lower mechanical load capacity is obtained.
    [011] From DE 195 43 799 A1 another brake disc mounted on a shaft is known, and between the friction rings, produced from a material of the carbon group, there are support bolts extended in order to absorb the high contact pressure force of axially acting inserts. Here, the screws are incorporated with a collar, as a result of this the contact pressure forces of the inserts can be transmitted positively. Such construction is known for shaft-mounted brake discs with friction rings, which are produced from ceramic or carbon group material. The form of construction of the brake disc on shaft is used in particular because it positively joins the connections between the friction rings of a material of the carbon group to a hub which, as a rule, is produced from a material of steel, not can be used simply. Therefore, screw connections or other connection techniques not positively associated or positively associated are employed, where in the joint assembly between the friction rings and the hub elements are often additionally arranged which compensate for the different thermal expansion between the hub, of a material. in steel, and friction rings made of ceramic or material from the carbon group, for example, formed by slotted nuts.
    [012] Brief description of the invention: object, solution, advantages
    [013] It is therefore the object of the present invention to provide a shaft-mounted brake disc with friction rings of a steel material, which can withstand high mechanical loads and makes good internal ventilation possible.
    [014] Starting from a shaft-mounted brake disc, this object is solved with a hub and friction rings according to the state of the art and the characterization features of claim 1. Advantageous developments of the invention are demonstrated in the dependent claims.
    [015] The invention includes the technical teaching that the shaft-mounted brake disc is constructed with a hub and two friction rings produced from a steel material, which are arranged parallel and spaced from each other in the hub, in which , between the friction rings, support screws are arranged to absorb a contact pressure force from the axially acting inserts.
    [016] Here the friction rings can form a separate assembly, which can be mounted independently of the hub and form a pair of friction rings together with the support bolts. This assembly can then be connected to the cube through known methods, which cube, in turn, constitutes an independent component. Therefore, friction ring and hub can be produced and supplied independently of each other. This offers an advantage above all when replacing friction ring pairs on a hub.
    [017] So, the axle-mounted brake disc comprises several individual parts, which are formed by at least one hub, two friction rings produced from a steel material and a number of support bolts. Similar to the construction of a ceramic or carbon brake disc, also known by the term carbon brakes, an axle brake disc according to the invention can also be supplied as an assembled brake disc, with which all components functionally essential consist of a steel material. In particular, friction rings can advantageously be extracted from a steel plate, for example, by laser cutting, by means of water jet cutting or other thermal or abrasive cutting method, but friction rings they can also be mechanically cut from a steel plate. The screws can be produced from any materials, but preferably also steel. The hub, in particular, can be produced from steel in order to avoid thermal distortions induced by expansion with a shaft, on which the shaft brake disc is mounted.
    [018] As a result, a shaft-mounted brake disc is provided according to the invention, which can be assembled from various materials in the form of a modular system. In addition to free material selection, it is also advantageous that the geometry of the friction ring pair and/or the hub can be changed as desired. For this reason, the friction ring pair can be quickly adapted to changed peripheral conditions and differently incorporated friction ring pairs can be assembled and disassembled from a single hub through quick replacement.
    [019] However, the friction rings are formed, in particular, of a steel material, in which at least in the case of the support bolts a free material selection becomes possible in order to optimize the individual components of the disc. axle brake in relation to its mechanical and thermal loads. Finally, the weight of the brake disc on shaft can be further optimized since geometric shapes can be employed which, strictly speaking, from a casting point of view, cannot be produced.
    [020] Advantageously, friction rings can include poles into which support screws are inserted at the end. Support screws can be designed for symmetrical rotation and have a middle portion and pins at the end. When mounting the brake disc on the shaft, the pins of the support bolts at the end can be inserted into the holes in the friction rings. The length of the pins in this case determines the thickness of the brake disc on the shaft, which can be, for example, 80 mm.
    [021] The middle portion of the support bolts may be larger than the diameter of the pins at the end or the middle portion of the support screws is designed smaller than the diameter of the pins at the end. In particular, it may be advantageous to provide bearing screws having a middle portion with a smaller diameter. This is to accommodate the tolerance of the boards. In addition, inspection of the weld bead is possible. Furthermore, the thickness of the friction rings can be compensated with no additional mechanical machining required.
    [022] The connection between the support bolts and the friction rings, in particular, between the pins at the end, which are inserted into the holes of the friction rings, can be produced through a press-fit connection (press- fit), through a weldable connection, through a welded connection, or through a riveted connection. Finally, a screw connection can also be advantageously produced using connection screws. If the connection between the support screws and the friction rings consists of a weldable connection, this can be produced, for example, by high-temperature soldering or brazing. Here, soldering temperatures can be employed, which do not occur during normal brake disc operation.
    [023] If the connection between the support screws and the friction rings is produced via a soldered connection, laser beam soldering, electron beam soldering or other possible soldering methods can be employed here, for example. Especially with electron beam soldering, the thermal power of the components to be joined is minimal, so that in particular it can only develop minimal thermal distortion through the friction ring soldering method and that is why this method should be advantageously employed. Through the materially bonded connection it is advantageously achieved that the heat which develops in the friction rings through the operation of the brake disc on shaft can be directed to the bearing screws so that the heat can be particularly effectively discharged through the internal ventilation .
    [024] With particular advantage, the weldable connection can be produced in a suitable furnace, in which, at the same time, the high welding temperature can be accompanied by a heat treatment, for example, of the friction rings. Through this connection technology the advantage obtained is that with the connection process, ie the high soldering temperature, a hardening process of the additional components, in particular the friction rings, can also be created. Because of this, several advantages are achieved as an ideal material is created that does not have its material properties changed through further machining or connecting operations, and this can be achieved by creating the connection in addition to hardening in a single operation, an advantage production also in terms of costs is achieved.
    [025] It is also advantageous to arrange the cooling elements between the friction rings, which, in particular, are welded or weldable inside the friction rings. Furthermore, the coolant elements can be screwed into the friction rings or weldable at the end.
    [026] Cooling elements increase the energy storage capacity of the brake disc. In the process, heat is directed from the friction ring to the refrigeration elements where the discharge by convection takes place. Thus, the convection surface is enlarged by the cooling elements, as a result more energy can flow into the flow medium.
    [027] In addition, the cooling elements can be configured so that they favor the flow of cooled air through the shaft brake disc, in which the cooling elements, for example, have a turbine blade-like shape. The cooling elements can be plate elements or alternatively or additionally a number of support screws may be arranged in the cooling elements inside the friction rings, but which have a size that is smaller than the support screws that extend between the two friction rings and connect these to each other. With the arrangement of the shortened support bolts a further advantage is obtained in that the arrangement of such shortened support bolts can be effected to form an ideal ratio of capacity and cooling dissipation, and the individual geometry of the support bolts can be selected with great design freedom.
    [028] With additional advantage, the material of the cooling elements can be selected independently. Possible are steel and cast materials. In addition, however, non-ferrous metals such as aluminum or copper or their alloys can also be employed. The condition of the surface of the outer surface subjected to incident flow can also be optimized in relation to its thermal and flow-mechanical properties.
    [029] An inner row of support bolts can be provided, which have axial passages through which the connecting bolts can extend. Connecting screws, for example, can be screwed into an internal thread, which is inserted into one of the friction rings, or screw nuts are provided, into which connecting screws are screwed. In the case where the loading temperature is too high, the nut mounted on the connecting bolt at the end can be formed as a sleeve and, in this way, the thread decoupled from the effect of temperature. Furthermore, by using two sleeves the installation space can be saved. Thus, the clamping ring, the friction rings and in particular the support screws with the passages can be screwed together with full contact, as a result, a particularly rigid connection between the friction rings and the hub is achieved. In this version, slotted nuts are additionally used.
    [030] In the hub, shoulders can be molded which, directed radially outwards, extend between the friction rings and through which connecting screws are passed. Through the lugs, therefore, the braking moment can be transmitted from the friction rings to the hub, where the lugs can comprise recesses in which, in turn, slotted nuts can be inserted, which generally can consist of hardened and tempered steel or cast iron. In particular, slotted nuts may have less radial mobility in the recesses of the shoulders to compensate for differences in radial thermal expansion between the hub and friction rings.
    [031] In addition, friction rings can include radially inwardly facing protrusions that can engage recesses that are inserted into the hub. This achieves a positive connection, in particular to transmit the braking moments, which act from the friction rings in the hub.
    [032] Clamping rings can be provided, which on the outside contact the friction rings in the radial’internal region. Here, connecting bolts can extend through the clamping rings and at least through a part or a mold of the hub, where in particular ceramic washers can be provided, which are arranged between the bolt head of the connecting bolts or between Bolt nuts on the connecting bolts and the friction rings. This creates a heat barrier so that the higher temperatures that can build up in the friction rings are not transmitted directly to the hub. The clamping rings additionally serve the purpose that the connecting screws cannot be subjected to bending distortion, where the clamping ring can be formed of a material which is characterized by a low coefficient of expansion. Even hereby a heat transfer from the friction rings to the hub can be minimized.
    [033] The positively bonded connection of the friction rings and the hub is also suitable for obtaining a split version of the friction ring pair. For this purpose, the partition plane of the friction ring pair could be placed in the middle on the radially inwardly facing protrusions. Therefore, a definite component of the centrifugal forces acting on the split friction ring pair could be transmitted to the hub through the shoulders. Therefore, a possible partition of the connecting screw of the two halves of the friction ring could be dimensioned smaller.
    [034] Finally, the use of a positively bonded connection makes it possible to use hub diameters that are larger compared to current connections. Since, in this case, the braking moment is transmitted via the positive connection of the friction rings and hub, connecting elements, which in other embodiments transmit the braking moment, are omitted. Because of this, installation space can be saved, which can consequently be used to enlarge the hub diameter.

    [052] Preferred Embodiments of the Invention
    [053] Figure 1 shows a detail of an exemplary embodiment of an axle brake disc 1 according to the invention with a hub 10, in which a first friction ring 11, and a second friction ring 12 arranged spaced apart and parallel to the first friction ring 11 is arranged and which together form a pair of friction rings. The brake disc of axle 1 can be used in a brake system of a railway vehicle, and the friction rings 11 and 12 serve as friction partners for the brake pads, which, on the outside, can be pressed against the friction rings, 11 and 12 with a brake caliper. Between the friction rings 11 and 12 are arranged multiple support screws 13, which serve to absorb the contact pressure force of the axially acting inserts 14 and prevent deformation of the friction surfaces through static and dynamic shielding. Friction rings 11 and 12 are produced from steel material and are extracted from a plate material by laser beam cutting or water jet cutting.
    [054] Support bolts 13 have a middle portion 13a and pins from end portion 13b following middle portion 13a at end portion. End part pins 13b can extend through holes 15 in friction rings 11 and 12 and for connection between support screws .13 and friction rings 11 and 12, end part pins 13b can be weldable, soldered, glued or pressed into the holes 15.
    [055] The exemplary embodiment shown is comprises support bolts 13 with a middle portion 13a, which has a smaller diameter than end portion pins 13b. The diameter jump allows a visual inspection of the same after applying a method of material bonding the end part pins 13b into holes 15. Furthermore, the pins 13b are longer than the thickness of the plates used in order to absorb tolerance of these boards.
    [056] Furthermore, an additional row of support screws 13' is shown, through which the connecting screws 17 are passed, and into which the nuts of the screws 23 of the end part are screwed (detailed description see fig. 3 ). Additionally screwed in with the connecting bolts 17 and the bolt nuts 23 is a clamping ring 21, as a result of this, the connecting bolts 17 are not subject to bending stress.
    [057] In the bolt combination of the connecting bolts 17, slide blocks 18 are additionally provided, which are inserted into the grooves 31, and the grooves 31 are located on the protrusions 25, which are molded into the hub 10. The slide block 18 it is produced from hardened and tempered steel and has only a negligible influence on the heat conductivity between the friction rings 11, 12 and the hub 10.
    [058] In order to reduce heat transfer between the friction ring ring 11 and the clamping ring 21, ceramic washers 22 of fiber-reinforced ceramic or ceramic materials are located between the friction ring 11 and the clamping ring 21. Alternatively, the clamping ring can be produced from steel which has a low coefficient of thermal expansion.
    [059] Figure 2 shows another perspective view of the axle 1 brake disc with the hub 10 according to Figure 1, where the inner row of support screws 13' is shown, which are formed with axial passages 24 , through which the connecting bolts 17 shown in Figure 1 can be passed. Here it is shown that the friction ring 11 comprises radially inwardly facing protrusions 19 through which the bearing bolts 13' with the passages 24 protrude. a fixed connection can be created between the support screws 13' and the friction ring 11 when the connection screws 17 are passed through the axial passages 24. An additional row of support screws 13 shows an incorporation of the support screws 13 with a middle portion 13a, which has a smaller diameter than the pins of the end portion 13b of the bearing screws 13, which are connected to the friction rings'11 and 12, the friction ring 12 may have protrusions 19 thereof. way the d ring and friction 11, and support bolts 13' extend with their opposite end into protrusions 19 of friction ring 19 which is not shown in more detail.
    [060] Figure 3 shows the exemplary embodiment of the axle 1 brake disc according to Figures 1 and 2 in a cross-sectional view. The cross-section shows the hub 10 with radially outwardly directed protrusions 25, in which a protrusion 25 is visible in the cross-sectional view. In the protrusions 25, the friction ring pair of friction rings 11 and 12 is connected to the hub 10 in a way. of torque transmission. To connect friction rings 11 and 12 connecting bolts 17 are provided, which extend through holes in protrusions 25. In addition, connecting bolts 17 extend through support bolts 13' with respective passages, and on the located side on the opposite of the screw head of the connecting screws 17 are screw nuts of the screws 23 on the connecting screws 17. Consequently, the protrusion 25, the friction rings 11 and 12 as well as the support screws 13' are screwed together "with full contact" by means of connecting bolts 17. Below the bolt nuts 23 is located a clamping ring 21, whereby between the clamping ring 21 and the bolt nuts 23 ceramic washers 22 are shown. It is shown that the bearing bolts 13 extend between the friction rings, 11 and 12, and that they are solid incorporated, without through hole, and extend with their end part pin 13b into the holes 15 in the friction rings 11 and 12.arrangement shown advantageously enables a removal of the friction ring pair from the friction rings 11 and 12 with the bearing bolts 13 of the hub 10, simply by loosening the connecting bolts 17. For example, an exchange of a hot friction ring pair it can therefore be carried out simply, and depending on the installation situation of the brake disc of shaft 1, it will not be necessary to remove hub 10 from a shaft to replace the friction ring pair with friction rings 11 and 12 .
    [061] Figure 4 shows a friction ring 11 and 12 respectively in a perspective view. The friction ring 11 and 12 respectively can be extracted from a sheet material of suitable thickness by a thermal cutting method, for example by laser beam cutting. With laser beam cutting, oxygen is particularly suitable as cutting gas. Likewise, an abrasive cutting method can be employed, for example, waterjet cutting. On the flat friction surface of the friction ring 11 and 12 respectively, holes 15 are shown in which the bearing screws 13 with their end part pins 13b can be inserted. On the inside, the friction ring 11 and 12 respectively comprise protrusions 19 which face radially inwards, into which through holes 26 are introduced and through which the connecting screws 17 can be passed. The friction ring 11 and 12 respectively are situated on the hub 10 with a radial orientation, in which orientation the protrusions 19 of the friction rings 11, 12 are in alignment with the shoulders 25 of the hub 10.
    [062] Figure 5 finally shows a cube 10 in a perspective view, which comprises several protrusions 25 on its outer circumference. In the protrusions 25, through holes 27 are introduced through which the connecting bolts 17 can extend and which are in alignment with the through holes 26 of the friction rings 11 and 12 and with the axial passages 24 in the bearing bolts 13' . In some of the protrusions 25, slots 31 are inserted into which the slide blocks 18 shown in Figure 1 can be inserted.
    [063] Figure 6 shows another exemplary embodiment of a disc brake shaft 1 with a hub 10, which comprises lugs 25 that are formed radially outward. The shoulders 25 comprise passages through which the connecting bolts 17 are guided so that a connection with the friction ring 11 is created, through which the connecting bolts 17 likewise extend. Under the heads of the connecting screws 17, in turn, ceramic washers 22 are arranged, and in the shoulders 25 of the hub 10, milled grooves 31 are inserted, in which the sliding blocks 18 are inserted. The grooves 31 can also be milled. on friction surfaces. If the grooves 31 are milled into the shoulders 25 of the hub 10, a tool corresponding to at least half the height of the hub is required. In this exemplary embodiment, support screws 13 are also shown to have a middle portion 13a with a smaller diameter and end part pins 13b with a larger diameter, and support screws 13 are connected to the friction rings 11 and 12, with the pins of the final part 13b.
    [064] Figure 7 shows a cross-sectional view through the brake disk of shaft 1 according to the exemplary embodiment of Figure 6. The brake disk of shaft 1 comprises a pair of friction rings of friction rings 11 and 12, having bearing screws 13 extending between friction rings 11 and 12. In order to secure the friction ring pair of friction rings 11 and 12 to hub 10, hub 10 comprises radially extending lugs 25 out. Bolts and connection 17 can be passed through lugs 25, which also extend through holes 36 in friction rings 11 and 12. When bolt nut 23 is screwed into the free end of connection bolt 17, friction rings 11 and 12 can be bolted to lugs 25 of hub 10 "with full contact", where lugs 25 are located between friction rings 11 and 12. In this exemplary embodiment, too, a ceramic washer 22 is shown under the bolt nut. 23. If the friction ring pair of friction rings 11 and 12 have to be removed from the hub 10, the connecting bolts 17 can be removed in order to later easily make the hub 10 relative to the hub ring pair. friction. Thus, the shoulders 25 can be axially passed through the recesses 28 in order to remove the friction ring pair from the hub 10 without having to remove the two friction rings 11 and 12 from each other.
    [065] Figure 8 represents a perspective view of the friction rings 11 and 12, respectively, in which a multitude of holes 15 are introduced to receive the support screws 13. The holes 36 in the friction rings 11 and 12 for the passage connecting screws 17 are introduced into radially inwardly facing protrusions 19 between which recesses 28 extend. In some of the protrusions 19, grooves 31 for receiving slide blocks 18 are milled, as already shown in Figure 6, in the assembled state.
    [066] Finally, Figure 9 shows a perspective view of the hub 10 according to the exemplary embodiment of Figure 6 with lugs 25 projecting radially outwards, in which through holes 27 are introduced, through which the connecting bolts 17 can be passed (see fig. 7). The through holes 27 can be provided as through holes for the passage of simple connecting screws 17 with a threaded shank, and through through holes 30, which correspond to the grooves 31 introduced in the friction rings 11 and 12 to receive the slide blocks 18, cylinder pins can be passed to create a corresponding tolerance dimension between the hub 10 and the friction ring pair and to transfer the fit to the friction ring pair through the slide blocks 18. The holes passage holes 30 for the passage of the cylinder pins can, for example, have a larger diameter than the passage holes 27 for the passage of simple connecting screws 17.
    [067] Figure 10 shows the hub 10 in yet another embodiment of the shaft 1 brake disc with recesses 20, in which the protrusions 19 of the friction rings 11 and 12 are inserted. The protrusions 19 are radially inwardly facing and the pocket-like recesses 20 enclose protrusions 19 of friction rings 11 and 12 (friction ring 12 is not shown in perspective view). In addition, support bolts 13 are shown which extend between friction rings 11 and 12.
    [068] A row of pocket-like recesses 20 is closed axially; Due to this, one degree of freedom of movement of the friction ring pair 11, 12 in an axial direction is blocked. For complete axial clamping, a clamping ring 34, see Figure 14, with welded or weldable threaded pins 35, which are passed through holes 36 in the protrusions 19 of the friction rings 11, 12 and in the closed part of the hub 10, is screwed against the back of the pocket-type recesses, 20. This at the same time ensures that on breaking off a part of the friction ring 11, 12, the latter is blocked by the threaded pin.
    [069] Alternatively, a flat clamping ring 21 can be screwed directly onto the shoulders 25 of the hub 10. As a safeguard of the thread a self-locking thread or the so-called locking screw can be used.
    [070] To axially fix the friction rings 11 and 12, fixing rings 21 are shown, which are exemplary incorporated with axial protrusions 32, and through holes 33 in the fixing rings 21 thread elements can be passed in order to screw in the fastening rings 21 to each other. Here, the axial protrusions 32 of the clamping rings 21 can be pressed axially against each other or by screwing the clamping rings 21 together they can be at least axially clamped together. Thus, the friction rings 11 and 12 are axially locked and the torque from the friction rings 11 and 12 can be transmitted to the hub 10 through the protrusions 19 in the recesses 20.
    [071] Figure 11 shows the exemplary embodiment of the axle 1 brake disc according to Figure 10, in a cross-sectional view. The connection between hub 10 and the friction ring pair of friction rings 11 and 12, between which support bolts 13 extend, is shown. Hub 10 comprises lugs 25, into which holes 33 are introduced. Through holes 33 in one of the friction rings 12 and through holes 33 in lugs 25 in hub 10, threaded pins 35 can be passed which are located in a ring clamping 34. At the end of the threaded studs 35, bolt nuts 23 are screwed in so as to connect the friction ring pair to the hub 10 through one of the friction rings 12.
    [072] Figure 12 shows the friction ring pair of friction rings 11 and 12, in which the lower friction ring 12 are introduced holes 29 through which the threaded pins 35 of the clamping ring 34 can be passed. Holes 29 are inserted into protrusions 19 in friction ring 12, which extend radially inward. Protrusions 19 of friction ring 11 are offset relative to protrusions 19 of friction ring 12 by an angle of 30°, for example, so that accessibility of bolt nut 23 is ensured, see Figure 11 in this regard.
    [073] Figure 13 constitutes a cube 10 perspectively according to the exemplary embodiment of Figure 10. In the cube 10, several shoulders 25 radially extend outwards, which partially have axial protrusions 32, between which intermediate spaces are formed, in the which can engage the protrusions 19 of the friction rings 11 and 12. Thus, the braking moment can be transmitted between the shoulders 25 and the protrusions 19 through the positively associated connection and the screw connection of the friction ring 12 to the hub 10 through The threaded pins 35 of the clamping ring 34 only serve to axially secure the friction ring pair to the hub 10. In addition holes 33 are shown in the shoulders 25 through which the threaded pins 35 of the clamping ring 34 can be passed.
    [074] Figure 14 finally shows a perspective view of the clamping ring 34 with multiple threaded pins 35 axially located on said clamping ring 34. Thus, the use of clamping ring 34 with respect to clamping ring 21 in Figure 10 is an additional alternative to connecting the friction ring pair to hub 10.
    [075] In this embodiment, the invention is not restricted to the preferred exemplary embodiment referred to above. A number of variants are conceivable that make use of the solution shown even with fundamentally different types of embodiments. All features and/or advantages arising from the claims, description or drawings, including design details or spatial arrangements may be significant to the invention either by itself or in a wide range of combinations.
