Definitions

  • the invention relates to a multi-part, built wheel for motor vehicles, in particular passenger vehicles or motorcycles.
  • Known steel wheels of this type generally consist of a one-piece rim ring and a base support, via which the wheel is attached to a hub of the respective motor vehicle.
  • the wheel is usually fastened with several bolts.
  • a screw-on flange is usually formed on the base support, into which a plurality of screw-on openings, preferably provided with a conical seat, are formed.
  • the screw bolts are inserted through these openings and screwed into corresponding threaded bores of the hub or of the brake arranged on the hub.
  • the base carrier and the rim ring manufactured separately from it are usually welded together.
  • tabs which are bent outward are formed on the outer edge of the base support, which abut the inner surface of the rim ring and on which the welding is carried out.
  • Wheels of the type described above can be manufactured inexpensively and are therefore standard equipment for most motor vehicles. In many cases, however, they are not enough for the increased Claims of the buyers regarding the external appearance of vehicles. To improve the appearance, a bolt circle can be formed in the basic carrier of such wheels, but such a design element cannot compete with spokes that have not previously been realized with steel wheel rims.
  • the invention has for its object to provide a wheel for motor vehicles that has a low weight and is inexpensive to manufacture with the greatest possible design freedom.
  • a multi-part, built wheel for motor vehicles in particular passenger vehicles or motorcycles, with a rim ring, which has a base carrier which can be fastened to a wheel hub of the respective motor vehicle and which is arranged in the opening surrounded by the rim ring and with one on the outer side of the Rades arranged cover shell is equipped, wherein the base bracket and the cover shell together carry the rim ring.
  • the cover shell is expediently positioned on the outside of the wheel facing away from the body of the motor vehicle after assembly.
  • a corresponding cover shell can be fastened in accordance with the invention on at least one of the outer sides visible after assembly. It is of course also possible with motorcycle bikes to arrange outer shells on both visible outer sides in the manner according to the invention.
  • the Cover in contrast to the decorative panels otherwise used in steel figs, the Cover not only functions as a pure design element, but at the same time absorbs part of the forces on the rim ring while driving.
  • the distribution of the forces absorbed by these two components, base carrier and cover shell, can be adapted to the particular design of the wheel. It is essential, however, that the cover shell always absorbs a significant proportion, preferably up to 50%, of the forces acting on the wheel during operation.
  • the invention thus provides a wheel which is distinguished by a freely configurable appearance and a reduced overall weight.
  • a wheel according to the invention can be manufactured particularly inexpensively due to the possibility of using prefabricated parts.
  • a wheel according to the invention thus combines the advantages of the optical appearance and the weight of light alloy wheels with the cost advantages that result from the production of conventional steel wheels.
  • the cover shell and the rim ring can be connected to one another in a force-locking, form-locking and / or material-locking manner.
  • one cohesive connection offers the use of suitable materials for the production of the individual parts of the wheel, the welding of the adjacent parts. Plasma welding is particularly suitable for this purpose.
  • the cover shell can also be glued or soldered to the rim ring, provided that the construction, the loads occurring during operation and the materials of the elements to be connected to one another permit this.
  • Screw-on openings should be provided on the base support in a known manner, via which the attachment to the respective hub of the motor vehicle takes place. These screw openings are preferably to be formed in a screw flange of the base support. Such a screw-on flange, which is generally formed in one piece with the basic carrier, can be designed in such a way that it forms an optimal contact surface for attachment to the hub of the vehicle and at the same time supports the rigidity of the wheel through its shape.
  • a particularly preferred embodiment of the invention is further characterized in that the cover shell and the base support can be screwed together to the respective hub of the motor vehicle by means of at least one screw connection.
  • both the base support and the cover shell are connected directly to the vehicle with the aid of the screw bolts used for fastening the wheel. In this way, all the forces absorbed by them are directed directly into the respective screw bolts, so that an optimal distribution of the forces absorbed by the rim ring onto the base carrier and the cover shell is ensured.
  • the cover shell can also be firmly connected to the base support in the area of the screw-on openings.
  • the cover shell can be welded, glued or soldered to the base support.
  • the cover shell can be firmly and nonetheless releasably connected to the base support by an independent screw connection.
  • a further embodiment of the invention which is important in practice is characterized in that the base support has at least one spoke via which the rim ring is connected to the screw-on flange.
  • the base carrier and the cover shell are spaced at least in sections, so that they enclose a space between them. This can be accomplished, for example, in that the base support has the shape of a U-profile in the area of its spokes, the open side of which is covered by the corresponding spokes of the cover shell. In this way, such a high rigidity of the overall construction can be achieved that a wheel according to the invention can also be designed as a spoke wheel.
  • Wheels according to the invention can be produced particularly economically if steel is used for their production.
  • This steel can be conventional carbon-containing steels used for this purpose.
  • Particularly good usage properties with an optimized appearance can, however, be achieved if the rim ring, the basic carrier and / or the cover shell are made of stainless steel.
  • the rim base can be made of sheets of different strength and / or thickness, taking into account the load required in the individual areas.
  • a ring element On the inner side of the base support facing away from the cover shell, a ring element can be arranged which, when mounted on the motor vehicle, holds the wheel at a distance from the respective hub of the motor vehicle.
  • this ring element takes on the function of a pure spacer, by means of which the wheelbase of the vehicle is enlarged.
  • the ring element can be used as a barrier against excessive heating of the cover shell and the base support. It is also conceivable to dampen the transmission of vibrations from the wheel to the chassis of the vehicle using the ring element.
  • FIG. 2 shows the wheel shown in FIG. 1 in a section along the line XX drawn in FIG. 1
  • 3 shows the outside of the wheel shown in FIG. 1 visible in the vehicle-attached state
  • FIG. 4 shows the inside of the wheel shown in FIG. 1, which is not visible when the vehicle is attached
  • Figures show a detail of a variant of the wheel shown in FIGS. 5-11 in longitudinal section.
  • the wheel 1 shown in Fig. 1 is made as a spoke rim wheel from pressed sheet steel parts. It is formed from a base support 2, a rim ring 3 and a cover shell 4.
  • the cover shell 4 which is visible from the outside in the assembled state can be made of stainless steel.
  • the base support 2 has a centrally arranged hub opening 5, the edge of which sits on an assembly aid formed on the respective hub when the wheel 1 is mounted on the passenger vehicle (not shown), for short "passenger car".
  • the hub opening 5 is surrounded by a ring-shaped screw-on flange 6, into which screw-in openings 7 are formed, which are distributed at regular angular intervals around the hub opening 5.
  • the edge region of the screw holes 7 is formed from the outside A of the wheel 1 tapered, so that a conical, self-centering seat is formed for the threaded bolt through the respective screw hole 7, not shown here.
  • Base support 2 has radially extending spokes 8, the ends of which are each tab-shaped and are bent in the direction of the outside A and welded to the inner surface 3 i of the rim ring 3.
  • the spokes each have a U-shaped cross section, which ensures a high degree of rigidity of the spokes 8.
  • the rim ring 3 is composed in the manner of a "Taylored Blank" from three ring-shaped molded parts 3a, 3b, 3c, which consist of steel sheets of different strength and / or thickness and are butt welded together.
  • the molded part 3a is bent in the radial direction at its edge section assigned to the outside A, so that the outer rim flange 9 of the rim ring 3 is formed by the bent edge section.
  • the rim ring 3 can consist of an annular molded part, which has different wall thicknesses due to flow pressures or different strengths as a result of the targeted work hardening (so-called "flow-forming rims").
  • the cover shell is placed on the base 2 from the outside A.
  • Their dimensions and shape are designed so that the base support 2 with its spokes 8 and its screw-on flange 6 and the rim ring 3 on the outside A are covered by corresponding shaped elements of the cover shell 4.
  • the cover shell 4 also has a central opening 10, a ring 11 with the position of the screw-on openings which is adapted to the shape of the screw-on flange 6 of the base support 2 and is arranged around the central opening 10 7 adapted through opening 12, around the ring 11 arranged spoke covers 13 and an outer ring 14 covering the rim ring 3 on the outside A.
  • the spoke covers 13 covering the spokes 8 of the base support 2 likewise have a U-shaped cross section, their legs 13a, 13b pointing in the direction of the inside I of the wheel 1 opposite the outside A. In this way, the spokes 8 are covered in their lateral region, which is otherwise visible from the outside A. At the same time, the U-shape of the spoke covers 13 ensures a high dimensional stability of the cover shell 4.
  • the peripheral portion 14a around the circumference of the outer ring 14 of the cover shell 4 is folded around the rim flange 9 formed on the rim ring 3, so that the rim ring 3 and the cover shell 4 are positively and non-positively connected to one another in this area ,
  • the ring 11 of the cover shell 4 rests on the screw-on flange 6 of the base carrier 2 and the edge regions of the through openings 12 of the cover shell 4 cover the edge regions of the screw-on openings 7 of the base carrier 2.
  • a ring element (not shown here) can be arranged between the surface of the screw-on flange assigned to the inside I, which keeps the wheel 1 at a fixed distance from the respective hub and prevents excessive heating of the wheel by the heat generated when the vehicle brakes.
  • the ends of the spokes 8 of the base support 2 assigned to the rim ring 3 are bent in the direction of the inner side I and welded to the inner surface 3i of the rim ring 3.
  • the rim ring 3 does not have an outer edge region shaped into a rim flange, but ends in the direction of its width approximately at the height of the spokes 8.
  • the rim flange 9a is instead formed by the multiply cranked outer edge region of the outer ring 14 of the cover shell 4. The offset is designed so that its edge 14a butt abuts the rim 3e of the rim ring 3 assigned to it.
  • the rim ring 3 and the cover shell 4 are firmly bonded to one another in the region of their abutting edges 3e and 14a by a circumferential weld seam S.
  • the integral connection can also be produced by welding limited to certain sections or points.
  • the outer edge section of the rim ring 3 forming the rim flange 9b is folded around the outer edge 14 of the cover shell 4.
  • the rim ring 3 and the cover shell 4 are also firmly bonded to one another by a weld seam S.
  • the rim flange 9c is formed, as in the variant according to FIG. 5, by an offset of the outer edge region of the outer ring 14 of the cover shell 4.
  • the leg 14b of the bent portion assigned to the rim ring 3 extends only in the radial direction, while the rim ring 3 projects in the direction of the outside A beyond the end of the spokes 8 of the base support 2. In this way, the leg 14b and the rim ring 3 meet in an edge region in which they are firmly connected to one another by a weld seam.
  • the variant shown in FIG. 8 also corresponds in principle to the designs of the wheel 1 shown in FIGS. 5 and 7.
  • the rim flange 9d is formed by an offset of the outer ring 14 of the cover shell 4.
  • the bent leg 14c of the outer ring assigned to the rim ring 3 only extends over approximately a third of the height of the rim flange 9d. There it meets the edge of the outer edge region 3g of the rim ring 3, which in this case is cranked in the radial direction as in the example shown in FIG. 1.
  • the rim ring 3 and the cover shell 4 are connected to one another by a weld seam.
  • the bent-off edge region 3h of the rim ring 3 and the outer edge of the outer ring 14 of the cover shell 4 lying flat on the edge region 3h meet at the circumferential free edge of the rim flange 9e and are there through a all-round weld seam joined together.
  • the outer edge region 14f of the outer ring 14 of the cover shell 4 is double-cranked, as in the example shown in FIG. 5, so that its free edge portion 14f 'pointing towards the inner side I essentially runs parallel to the edge region 3j of the rim ring 3 which is extended beyond the end of the spokes 8.
  • This extended edge area 3f lies on the edge section 14f 'and extends into the corner area at which the edge area 14f' bends radially to the rim flange 9f.
  • the rim ring 3 and the cover shell 4 are firmly connected to one another by a weld seam S introduced into this area.
  • the ends 8f of the spokes 8 which are bent in the direction of the inner side I lie on the underside of the edge section 14f 'facing away from the rim ring 3.
  • the edge section 14f 'and the ends of the spokes 8 are likewise firmly connected to one another by the weld seams S'.
  • the free edge of the cranked edge section 14f is welded to the inner surface 3i of the rim ring by a weld seam S ".
  • the outer edge region 14g of the outer ring 14 of the cover shell 4 is coming from the outside around the peripheral edge region 3k of the rim flange 9f of the rim ring 3 placed so that the rim ring 3 and cover 4 are non-positively and positively connected.
  • the base support 2 has an edge region 2 a formed on its outer circumference, which covers the rim ring 3 over an edge region 3 m extending from its base 31 on the outside assigned to the cover shell 4. Both in the area of the groove 15 formed between the bottom 31 of the rim ring 3 and on the peripheral edge 2b of the base support, the rim ring 3 and the base support 2 are welded to one another.
