<p>SPRING-SET CALIPER BRAKE A spring-set power-released caliper brake, adapted to grip the sides of a clamped member and, specifically, to provide a substantially uniform clamping force irrespective of actuator spring extension. The caliper brake includes a base mounted in fixed relation with respect to the clamped member. An actuator lever and an actuated lever are pivotally mounted in the base intermediate their ends. One of a pair of brake shoes is pivotally mounted on one end of each lever. The cylinder portion of a spring-set, power-released linear actuator is secured to the other end of the actuator lever and a compensating link is pivotally mounted in the other end of the actuated lever. The thruster portion of the linear actuator is pivotally connected to one end of the compensating link. One end of a toggle link is intercannected to the other end of the compensating link and the other end of the toggle link is interconnected to the actuator lever.</p> |
