Abstract
A chassis component for a motor vehicle is disclosed. The chassis component (1) is manufactured at least partially from a multi-layer steel sheet (10, 20, 30). The multi-layer steel sheet (10, 20, 30) includes at least three steel layers, including two outer steel layers (11, 12; 21, 22; 31, 32) and one inner steel layer (13, 23, 33). At least one outer steel layer (11, 12; 21, 22; 31, 32) of the multi-layer steel sheet (10, 20, 30) has a tensile strength of at least 1200 MPa. A method for producing a chassis component for a motor vehicle, in particular a wheel (1) or a part thereof, is also disclosed.
Claims16
A chassis component for a motor vehicle, comprising:
- a multi-layer steel sheet,
- wherein the multi-layer steel sheet comprises at least three steel layers, comprising two outer steel layers and one inner steel layer, and
- wherein at least one of the outer steel layers of the multi-layer steel sheet comprises a tensile strength of at least 1500 MPa and a carbon content of at least 0.25 wt %.
A method for producing a chassis component for a motor vehicle, the method comprising:
- providing a multi-layer steel sheet, wherein the multi-layer steel sheet comprises at least three steel layers comprising two outer steel layers and one inner steel layer, wherein at least one of the outer steel layers of the multi-layer steel sheet has a tensile strength of greater than 1500 MPa and a carbon content of 0.25 wt %;
- and
- deforming the multi-layer steel sheet to form the chassis component.
