Definitions
- the invention relates to a vehicle wheel with a rim made of sheet steel for receiving a tire and an inextricably attached to the wheel rim made of sheet steel with a connection area for releasable connection to a wheel, with a design element made of metal, which force with the wheel and / or the rim -, Formally and / or materially connectable or connected.
- Vehicle wheels or vehicle wheels are safety components and therefore must be able to withstand the high mechanical and dynamic cyclical loads during ferry operation.
- Conventional "steel wheels” in sheet metal construction consist of a wheel disc (wheel disc), which ensures the connection to the wheel hub and a rim (rim tape), which receives the tire.
- the wheel components are nowadays invariably produced by cold forming in the multi-stage process (deep drawing, flow-forming, profiling).
- the design plays an essential role and decisively determines the customer acceptance or purchase decision.

- US Pat. Nos. 2010/0194181 A1 and US 2011/0163593 A1 are cited for wheel systems with a detachable design element.
- a disadvantage of this con struction is the fact that the releasable and known fastening systems can lead to a signifi cant additional weight and NVH problems of the wheels and the resulting design over "aluminum wheels" is greatly improved.
- plastic caps available on the market can be greatly improved with regard to the visibility of the rear steel wheel structure (degree of coverage) as well as the aesthetics and appearance. Compared to the production costs of the steel wheels, the costs for plastic covers are not insignificant. Furthermore, due to the releasable connection between the wheel and the design element, NVH problems (noise vibration harshness) can arise.
