Tread-disc assist dual truck mounted brake assembly

摘要

Brake system for retarding rotating machinery. It has an actuator with a first portion and a second portion. Actuator is supplied with energy and generates force causing relative motion of the first and second portions. The second portion is connected to an actuator lever and the first portion is connected to a brakebeam. The lever has a second pivot connection also connected to the brakebeam and it has a third pivot connection attached to a reaction device. The reaction device is connected to an equalizer lever which is connected to a second brakebeam and a second reaction device. The second reaction device is connected back to the first brakebeam, or to the first portion of the actuator. The brakebeams each have three pivot connections at each end. Two are about parallel to the brakebeam and one is perpendicular. A pair of brake hangers are pivotally attached to the two parallel pivot connections and a proportionalization lever is pivotally attached to the vertical pivot connection. It receives force from the brakebeam and conveys the force to a force delivery mechanism at each of its ends. Each brake hanger has a force receiving mechanism to receive force from the force delivery mechanism at the ends of the proportionalization lever and each brake hanger has a brake shoe for forcible application to the rotating machinery to retard the rotating machinery.
