    专利说明:

    [0001] The present invention relates to a cube star with profile radii that is composed of at least two individual parts that combine with each other in a positive locking manner.
    [0002] Many constructions are known that use cube stars made of composite fibers. Often, during the manufacturing process, they are initially made as stars on the disk hub and, after consolidation, are recessed, for example, by means of CNC milling. The continuous course of the fibers is naturally interrupted in the process. This has an adverse effect on the strength of the final product.
    [0003] The type of construction of a wheel made of composite fibers, according to document no. DE 10 2010 010 512 A1, provides the connection of the star of the disc-shaped hub to the rim cavity through a recess, which is performed by braiding around the circumferential contour of the cube star. The need for a circumferential contour disadvantageously leads to limitations on the design freedom of the cube stars.
    [0004] Another known construction (document no. DE 10 2006 051 867 A1) provides a hub star made of composite material which is composed of ring-shaped radius segments located one above the other and consists of fabricated circumferential unidirectional fiber strands through winding technology. This manufacturing method is very expensive and requires a large number of different operations that can only be automated with great difficulty. Furthermore, a wheel of this construction has only a low impact strength.
    [0005] The objective, therefore, is to propose a wheel construction that offers a great freedom of design of the hub star, but also meets the high demands of the automobile industry in terms of impact resistance.
    [0006] The wheel according to the present invention has a hub star and a rim, wherein the rim itself again comprises a rim cavity and wheel flanges. The wheel preferably consists entirely or partially of composite fiber or metal. The rim preferably consists entirely of composite fiber or metal. The star of the cube comprises two molded parts, the first molded part forming spokes with an open profile cross section. The wheel or first molded part has two, three or more spokes. The spokes have a geometric axis of profile that extends along their longitudinal extension, usually from the wheel hub to the rim. The second molded part closes the open profile cross section along the geometric profile axes of the first part entirely or only partially. The first molded part preferably consists of composite fiber, although the second molded part may consist of composite fiber or metal. In another preferred embodiment, the first molded part also consists of metal and the above-described methods of processing composite fibers are replaced by corresponding metal processing methods (deep stamping, laminating, etc.) which are known to the person skilled in the art. The wheel hub is preferably also integrated with the hub star and is formed of one or two molded parts, the second molded part preferably forming especially the wheel hub. The wheel hub is also preferably formed together from both molded parts. The profile cross sections of the first and second molded parts are preferably U-shaped in the spoke area and the openings of the two molded parts are facing each other and spaced apart and the profile cross section of a molded part closes that. the other part in a similar way to the clamp. The profile cross section of the molded first part preferably closes especially that of the second part. In other preferred embodiments, the cross sections of the profile are conically combined with each other or by forming a snap-in connection or abut each other, forming a butt joint.
    [0007] Preferred embodiments are those in which the geometric profile axes are closed at the ends of the second molded parts located on the outside, so that at least one fully closed cavity is formed between the first molded part and the second molded part. Thus, contamination of the gap between the first molded part and the second molded part is advantageously avoided. In addition, open ends of the second molded parts are also preferred, which in turn advantageously improves the cooling of the hub star.
    [0008] The two parts of the hub star are connected to each other in a positive locking manner preferably by the axially directed areas of the profile spokes, as well as the wheel hub flange that matches each other, so that by at least one, typically two or more contact surfaces are formed. The two molded parts are preferably connected to each other on these contact surfaces. This connection is preferably carried out in a positive locking manner (by means of a press-fit connection of the two molded parts to each other) or by actual connection (by means of an adhesive connection or a welded connection). A combination of an actual connection and a positive locking connection is also possible.
    [0009] The hub star is preferably connected to the rim cavity by a recessed connection of the radius segments. In the present context, the ends of the individual spokes are preferably connected to the rim cavity in a positively locking manner by braiding (pre-forming the rim cavity by means of the braiding method). The fully or partially consolidated ends or even the unconsolidated ends of the spoke segments are braided for this during rim cavity fabrication. A positive locking connection and, if the same matrix material (or chemically bonding matrix materials) is used, also an actual connection develops with the molded part matrix material due to impregnation with matrix material and the subsequent consolidation of the rim cavity.
    [0010] The connecting surfaces of the spokes with the rim cavity are widened in another preferred mode through strips that enter and exit tangentially. These are preferably formed by the ends of the spokes that flex parallel to the inner circumference of the rim and thus extend in some sections on the inner side of the rim.
    [0011] In a preferred embodiment, the first molded part has the hub. It possibly surrounds the shaft opening and has openings for the screws. The second molded part completely or partially closes the open profile cross section of the first molded part and similarly has screw holes. At least one spacing element made of metal or composite fiber that absorbs the compression force of the screws is preferably located for load absorption between the first and second molded parts, as well as surrounding the screw holes. The spacing element is preferably positioned in the first part molded by a flat load-absorbing element (preferably one made of metal). In an especially preferred embodiment, the second molded part itself consists of metal and acts as a load-absorbing element by absorbing the pressing force of the screws. The second molded part is not empty, in the present context, at least around the screw holes, but is of continuous material, so that the pressing force of the screws is absorbed on both sides and supported by the molded part.
    [0012] The spokes can advantageously have any desired cross-sections, which makes it possible for the star rim to have a correct shape for the charge, with U-shaped profiles correspondingly being especially preferred.
    [0013] The wheel preferably consists of fiber reinforced plastic. Carbon fiber reinforced composites, for example with epoxy resin as the matrix material, are preferably used as material combinations. Steel, aluminium, titanium or magnesium or the alloys known from the prior art for manufacturing wheels are especially preferred for embodiments which are manufactured partially or entirely from metal.
    [0014] The construction according to the present invention makes it possible advantageously to further reduce the weight due to the looser radius geometry. Furthermore, this is advantageous as there is no need for CNC finishing operations so that the fiber structure reinforcement remains undamaged. Thus, an especially high impact strength of the hub star can be achieved. EXEMPLIFYING MODALITIES
    [0015] Exemplary modality 1, according to Figure 1, Figure 2 (a to c), Figure 3, Figure 4 (a to c) and Figure 5:
    [0016] In the first exemplary embodiment, the hub star is composed of two separate molded parts (2, 3) that form the spoke segments as well as the wheel hub. The radius segments of the first molded part (2) are characterized on the side of the vehicle by an open cross section. Detail X shows the cross-section of a ray, that in the area in which the molded part 2 does not close the opening in the U-shaped cross-section of the first molded part (2). It can be seen in detail Y the way in which this opening is covered in another area by the second molded part (3), which combines with it in a positive locking manner and, similarly, has a shaped cross section of U. The spokes are integrated axially and radially by means of a positive locking connection (Figure 3) in the textile frame of the rim cavity (1). The undercut is formed by the axially directed side areas (4) of the radius cross section which are bent in the direction of the central geometric axis of the radius under the lower base connection and thus ensure a flat connection (5). The connecting surface or hub star of the hub is incorporated by a second molded part (3), which results in the complete closure of the cross section of the spokes (Figure 2a, detail Y). The second molded part can, at this point, be designed so that the open radius cross section is partially (Figure 2a) or completely closed in the radial direction downward from the lower rim base (Figure 2b). Furthermore, the radius ends of the second molded part can be designed so that a closed cavity protected from external means is generated between the two molded parts (Figure 2c). The number of radius segments can be selected as desired.
    [0017] The two molded parts (2, 3) are connected together in a positively locking manner through the axially directed areas of the radius profiles and the hub centering (6), which results in the formation of a possible surface binding. The connecting surfaces of the two molded parts can be directed relative to each other axially (Figure 4a), conically (Figure 4b) and/or by means of a snap-fit connection (Figure 4c) to center the two molded parts. Furthermore, the two molded parts are aligned with respect to each other through the spacing segments (7) which are received by the flatly connected load applying element (8) which is additionally used to absorb the wheel bolt elements and thus positioning the second molded part (3) accurately.
    [0018] Exemplary Modality 2, according to Figure 6, Figure 7, Figure 8 (a to b) and Figure 9:
    [0019] The hub star, similarly, consists of two molded parts of composite fiber in this exemplary embodiment. The open cross-section of the spokes is located, in the present context, on the outward-facing side of the vehicle, so that the connection of the spoke segments to the rim cavity can take place over a large area. In addition, the spokes are connected to the lower base of the rim cavity by a recessed positive locking connection and the recessed strips of the spoke segments (5) can be integrated over or within the braided textile structure of the rim cavity (Figures 8a, 8b). This molded part (2) at the same time assumes the function of the wheel hub connecting surface of the wheel. The second molded part (3) is positioned by means of correspondingly spaced segments and thus completely closes the open cross section of the radius segment.
    [0020] The two molded parts (2, 3) are connected together in a positive locking manner through the edges of the spoke profiles and the hub centering (6), which results in the formation of a possible connecting surface.
    [0021] Exemplary modality 3, according to Figure 10, Figure 11 and Figure 12:
    [0022] This exemplary modality differs from the previous ones in that the hub star is composed of a metallic load application element (9) and a molded part made of composite fiber (2). The molded part with the spoke segments and the wheel hub connecting surface is connected to the rim cavity, as described in exemplary embodiment 2. The metal load-applying element (9) is characterized by a circumferential wavy contour, which results in the integration of the element used to receive the wheel bolt elements between the axially directed areas of the spoke segments and the hub centering of the molded part, so that it is secured against rotation (Figure 12 ). The contact surfaces can be used at this point for an additional bonded connection.
    [0023] Exemplary modality 4 according to Figure 13, Figure 14, Figure 15 and Figure 16:
    [0024] This exemplary modality differs from exemplary modality 1 in that the two molded parts are joined together with a cross section of profile, preferably U-profiles, which are open on the side of the vehicle (Figure 13). The junction zone (10) thus formed can be used as a bonding surface. Furthermore, the joint zone (10) can be designed so that the connection of the two molded parts is incorporated by means of a butt joint (Figure 14) or an overlap connection (Figure 15). The positive locking recessed connection between the molded first part and the rim cavity can be realized, in the present context, by means of the rim cavity safety protrusion (protrusion) (Figure 16).
