Definitions

• Vehicle wheel in sheet metal construction in particular made of sheet steel
• the invention relates to a vehicle wheel in sheet metal construction, in particular made of sheet steel, with a rim and a rim and an outside and an inside rim flange and a wheel rim connected to the outside rim flange and supporting the rim bed, which has a central fastening area and in and around this fastening area Ring area has ventilation openings, the wheel disc is formed with a single shell and tabs are connected to the radial outer edge of the ventilation openings, which extend in the direction of the rim well and are firmly connected to the rim well.
• Vehicle wheels in sheet metal construction are known in various designs. Vehicle wheels made from sheet steel as well as aluminum sheet are known from practice and / or the literature.
• the wheel bowl is composed of two sheet metal parts which lie firmly on top of one another in the central fastening area and in the ring area around this area, while they diverge in the area near the rim and to the rim flanges, where they are encircled by these are.
• the part that runs to the inside of the rim flange additionally forms a support for the rim base.
• the tabs are formed by parts cut out in a tongue-like manner from the outer ring region of the wheel disc.
• the webs lying between these cut-free areas are flat and merge into the central area, which is closed in the circumferential direction and adjoins the central fastening area.
• Such a vehicle wheel gives the visual impression of a substantially closed wheel bowl with ventilation openings located in the outer ring area.
• Such a vehicle wheel cannot be compared with the pleasing appearance of a cast aluminum wheel with spokes.
• the invention has for its object to provide a vehicle wheel in sheet metal construction, which is inexpensive and easy to manufacture and has high rigidity.
• the radial webs remaining between the ventilation openings extend as far as the fastening region and are designed as spokes with a stiffening profile, the stiffening profile in particular being arcuate. Because of this special type of connection of the wheel disc to the wheel rim in connection with the design of the webs as spokes, the wheel according to the invention has a high degree of rigidity and at the same time the pleasant appearance of a spoke wheel.
• the manufacture of the vehicle wheel is particularly easy if, according to one embodiment of the invention, the ring area has parts cut out in a tongue-like manner to form the ventilation openings and the tabs, the cut-out, tongue-like parts forming the tabs only with the wheel disc on their radial outer edges are connected and parked on the inside of the wheel.
• the wheel disc is made in one piece.
• the tabs therefore do not need to be connected to the wheel hub separately, for example by welding or soldering.
• the stiffness of the vehicle wheel can be further increased in that cavities are formed between the tabs and the rim. This can be optimally achieved, in particular, if the rim bed is designed as a low bed.
• the wheel rim is positively connected on its outer edge to the outer rim flange, in particular if the rim flange is flanged from the outer rim of the wheel flange.
• This training also has an aesthetically positive effect.
• the connection between the rim base and the brackets of the wheel disc is cohesive. MIG soldering is particularly suitable as a material connection for materials that are difficult to weld.
• the sheet thickness of the rim and / or the wheel disc is preferably in its axial course or radial
• the wheel disc which has a decreasing operational cross-sectional load with increasing distance from the wheel axle, can be increasingly thinned out accordingly in the sheet thickness.
• the measures for weight optimization can be combined during production by thinning the bowl and flanging the rim flange in one work step.
• both parts can be made of corrosion-protected, in particular galvanized or aluminized, steel sheet.
• the rim and, in particular, the wheel disc determining the appearance can be made of stainless steel.
• Dual-phase steel, TRIP steel or LIP steel is particularly suitable for the wheel bowl.
• LIP steel is particularly suitable for the rim.
• the wheel disc can be produced by hot forming.
• it consists of a tempered steel, e.g. quality 22 Mn B 5.
• the sheet metal blank to be formed can be brought to the required forming temperature outside or in the forming tool. After the forming, there is a targeted cooling to adjust the material strength, preferably when the wheel disc is still in the forming tool.
• FIG. 2 shows the vehicle wheel according to FIG. 1 in partial cross section along line II-II of FIG. 1,
• Fig. 3 shows the vehicle wheel of FIG. 1 in partial cross section along the line III-III of FIGS. 1 and
• FIG. 4 shows the vehicle wheel according to FIG. 1 on an enlarged scale
• the vehicle wheel consists of two joined sheet metal parts, namely a rim 1 and a wheel bowl 2. Both the rim 1 and the wheel bowl 2 consist of sheet steel.
• the rim 1 has a rim bed 3 designed as a low bed and two rim flanges, of which only the outside rim flange 4 is shown in FIGS. 2 and 3.
• the wheel disc 2 has a central fastening region 5 with screw holes 6 for wheel bolts, an annular region 7 lying around this fastening region 5 with essentially trapezoidal ventilation openings 8 and an outer ring region 9.
• parts are cut out of the solid material in such a way that the cut-out parts are only connected to their outer edges 10 in the manner of tongues.
• the cut-out parts are bent toward the inside of the wheel and form tabs 11.
• the tabs 11 extend into the area of the drop center 3, where they rest against the rim base and are integrally bonded thereto, in particular by MIG soldering 12 are connected.
• the tabs 11 form with the rim 1 stiffening, in particular torsion-resistant cavities 13.
• spokes 14 The radial webs remaining between the cutouts 8 form spokes 14. They are curved slightly outwards and have a stiffening profile in cross section, as the detailed section in FIG. 4 shows.
• the stiffening profile should primarily be designed for the transmission of high bending forces.
• the wheel bowl 2 is not only connected to the rim 1 via its tabs 11, but also with its outer edge, in that the outer rim flange 4 is positively encompassed by the outer edge 15 of the wheel bowl 2.
