Abstract
A self-centering apparatus for caliper brake assembly to control relative positions of brake shoes so that they are equally spaced from the brake disc, irrespective of attitude of brake. The caliper brake assembly has a pair of caliper arms hinged to the body thereof, with brake shoes at inner ends of the arm and a brake actuator extending between outer portions of the arm. A rocker device is hinged to the body for rotation about a rocker axis disposed parallel to the hinge axes of the caliper arms, and the rocker links interconnect the caliper arms and the rocker device so that movement of one caliper arm is essentially equal and opposite to movement of the remaining caliper arm.
Claims10
A caliper brake assembly having a body and a pair of caliper arms hinged relative to the body for rotation about at least one arm hinge axis, the arms cooperating with brake shoes adjacent inner portions of the arms and an actuator adjacent outer portions of the arms, the assembly being further characterized by:
- (a) a rocker means hinged freely to the body for rotation about a rocker axis disposed parallel to the hinge axis,
- (b) a pair of rocker links having outer portions thereof hinged to respective caliper arms at equal distances from the respective hinge axis, and inner portions thereof hinged to the rocker means,
- so that movement of one caliper arm is essentially equal and opposite to movement of the remaining caliper arm due to coupling between the caliper arms by the rocker means and rocker links.

- (a) a rocker means adapted to be hinged freely to the body for rotation about a rocker axis disposed parallel to the hinge axis,
- (b) a pair of rocker links having outer portions thereof adapted to be hinged to respective caliper arms at equal distances from the respective hinge axis, and inner portions thereof hinged to the rocker means,
- so that movement of one caliper arm is essentially equal and opposite to movement of the remaining caliper arm due to coupling between the caliper arms by the rocker means and the rocker links.
