BALL RAMP CALIPER BRAKE

摘要

A brake for a wheel is slidably mounted to a frame by mounting sleeves. The brake includes a stationary actuator having a plurality of depressions for receiving a plurality of balls. A pin, rotationally received in the stationary actuator, correspondingly defines a pivot axis. A rotating actuator rotates about an axis and includes a plurality of depressions axially aligned with the depressions while in an unactuated state. The brake is actuated by rotation of the rotating actuator which moves the balls to progressively more shallow portions of the depressions which acts upon a washer and one or more shims to force a first stator and a second stator together and into contact with a rotor. The stators are biased apart and are axially located by a pair of bridge sleeves such that the axes of the bridge sleeves are coplanar with the axis.
