Abstract
A vehicle brake assembly utilizes a damping mechanism to eliminate brake linings. The brake assembly includes a fixed base plate and an actuation plate rotatable relative to the base plate. The base plate includes a plurality of orientation slots and the actuation plate includes a plurality of actuation slots with each one of the actuation slots partially overlapping one of the orientation slots. A cam having a plurality of cam-lobes formed about the circumference is mounted for rotation with an axle shaft. A plurality of dampers interact with the cam to brake the vehicle. Each damper includes a mounting portion that extends through one of the orientation slots and the corresponding actuation slot, and which has a movable distal end that engages the cam. A motor and gear assembly control rotation of the actuation plate and cause the distal ends of the dampers to engage the cam to perform a brake actuation.
