摘要： Linkage which extends between right and left brake pedals and a valve construction provided with an outwardly extending shiftable shaft and a pair of valves disposed to either side of the shaft. A bolt assembly passes through one end of the shaft and mounts a yoke for rocking movement, the yoke having ends equally offset from the valves. Right and left substantially identical linkages are employed, each linkage including a push rod mounted for limited adjustable sliding movement in a trunnion carried by a bifurcated arm of a bell crank. The other bell crank arm is connected to an end of the yoke by a ball joint assembly, one end of a tubular intermediate portion being adapted to bear against a valve.

摘要： A brake assembly for engaging the periphery of a rotatable member, the brake assembly being energized by rotation of the rotatable member in either direction. The brake assembly includes a movable brake shoe which may be forced into contact with the periphery of the rotating member. The brake shoe has spaced apart rollers which are held in engagement with converging ramps on a wedge block. The brake shoe is permitted to shift laterally with respect to the ramps, and as the brake shoe engages the rotating member one of the rollers will move downwardly along one of the ramps to affect self-energization of the brake shoe. The wedge block is provided with a downwardly extending projection which is disposed between the converging ramps, the projection being received within a recess formed in the brake shoe, the recess being of greater width than the projection. The recess and projection limits the lateral shifting of the brake shoe which takes place during self-energization and permits disengagement of the brake shoe even when a lateral shifting force is being imparted to the brake shoe by the rotatable member which would normally cause further self-energization.
摘要翻译： 一种用于接合可旋转构件的周边的制动组件，所述制动组件通过所述可旋转构件在任一方向上的旋转来激励。 制动器组件包括可以被迫与旋转构件的周边接触的可动制动蹄。 制动蹄具有间隔开的辊，其保持与楔块上的会聚斜面接合。 允许制动蹄相对于斜面横向移动，并且当制动蹄接合旋转构件时，其中一个辊将沿着一个斜面向下移动以影响制动蹄的自动通电。 楔形块设置有向下延伸的突出部，该突出部设置在会聚斜面之间，突出部被容纳在形成在制动蹄内的凹部内，凹部的宽度大于突出部。 凹槽和突起限制了在自通电期间发生的制动蹄的横向偏移，并且即使当通过可旋转构件向制动蹄施加横向移动力时，也允许制动蹄分离， 通电
