ABSTRACT:
This invention relates to a brake assembly having a brake housing and wheel shaft rotatable in the housing. There is provided an armature plate in the housing secured to and rotatable with the shaft. Also provided is a movable actuator in the housing movable rotatably from an inoperative position to an operative position closer to the armature plate. An electromagnet is provided either directly mounted to the movable actuator or indirectly via a mechanical linkage. When the electromagnet is energized it causes the actuator to rotate with the armature plate and thereby move to an operative position where it forces a stationary brake disc and rotatable brake disc into engagement to achieve a braking action. This engagement is released upon de-energization of the electromagnet.
