ABSTRACT:
A brake pedal assembly including a pedal lever which is pivotally attached to a housing, a plate pivotally attached to the pedal lever, a push rod attached to said plate, and a pulley arrangement. The cable has a fixed length with a first end attached to the pedal lever and a second end attached to the plate. An operator input applied to the pedal lever moves the pedal lever in an arc about the pivotal attachment of the housing. As the pedal lever moves, the cable length between the pulley mechanism and the first end increases while the length between the pulley mechanism and the second end decreases. A decrease in the length of the cable between the second end and the pulley causes the plate to pivot with respect to the pedal lever. The arcuate movement of the first lever and the pivoting of the plate are combined to provide a push rod with linear movement for actuating a force receiver.
