A wheel assembly for an electric vehicle. The wheel assembly includes: a hub integrated with an electric motor; and a fluid-actuated fail-safe brake fitted to the assembly with at least one braking surface for frictional engagement with a rotor of the electric motor. The brake is engaged with the rotor in its unactuated state, and when the fluid is actuated, the brake is released to allow the rotor to rotate. A solenoid valve having a normally open state is in fluid communication with pressurized fluid for fluid actuation of the brake, and the solenoid valve is closed when powered, allowing fluid actuation to release the brake. In the event of a loss of power, the solenoid valve will return to a normally open state such that the brake is not actuated and applies a braking force to the rotor.

    一种用于电动车辆的车轮组件。该车轮组件包括:轮毂,其与电动马达成一体;和流体致动故障安全制动器,其利用至少一个制动表面装配到组件,该至少一个制动表面用于与电动马达的转子摩擦接合。制动器在其未致动状态下与转子接合,并且当流体致动时,制动器被释放以允许转子旋转。具有常开状态的电磁阀与用于流体致动制动器的加压流体处于流体连通,并且电磁阀在供电时关闭,从而允许流体致动以释放制动器。在失去电力的情况下,电磁阀将回复到常开状态,使得制动器未致动并且向转子施加制动力。
