摘要:
The invention relates to a vehicle wheel (1) comprising a rim (2) for receiving a tyre, and a wheel disc (3) which is connected to the rim (2) in an integrally bonded, force-fitting and/or form-fitting manner, with a connecting region (11) for the releasable connection to a wheel carrier, wherein the wheel disc (3) is formed from a steel workpiece which is heat-treated at least in regions. The problem of providing a commercial vehicle wheel which has high operating strength and safety in comparison to the known prior art is solved in that the wheel disc (3) has a heat-treated microstructure with a tensile strength of between 500 and 1300 MPa and/or a hardness of between 150 and 400 HV 0.1 at least in the transition region (8) for connection to the rim (2).
