Abstract
An improved braking system for a vehicle which has a wheel support in which an electric motor is housed having a drive shaft. A first and second planetary gear system are connected to drive the wheel from the motor drive shaft. The gear system includes a sun gear axially aligned with the shaft. A brake disc is supported by a disc carrier which is rotatably mounted on the gear housing. A floating disc adaptor is provided to transfer rotational movement of the sun gear to the disc carrier. Thus the brake disc rotates at the same rotational speed as the sun gear which is about five times faster than the rotation of the wheels of the vehicle.
