Brake disk for assembling in drive module for connecting electric wheel hub motor and brake device to motor vehicle, has friction ring and expansion elements, which are coupled with wheel or wheel hub motor in radial direction of brake disk

摘要

The brake disk (1) has a friction ring (2) and expansion elements (6), which are connected at one end (7a) with the friction ring and are coupled with a wheel or a wheel hub motor in the radial and circumferential direction of the brake disk at the other end (7b) facing away from the friction ring. The expansion elements are formed radially elastic. The expansion elements are extended, such that they have a radial directional component and a tangential direction component, and when the friction ring is heated, the radial component of the expansion element is shortened. An independent claim is included for a drive module for connecting an electric wheel hub motor, a rotatably mounted wheel and a brake device to a motor vehicle, a commercial vehicle or a rail vehicle.
