Abstract

A clutch and transmission brake assembly which can be readily incorporated into existing vehicle drive trains without undue modification. The assembly includes a wet clutch connectable to a flywheel and a transmission brake adapted to be disposed between the wet clutch and a transmission housing, the clutch and transmission brake being operated by annular pistons (56, 118). The assembly further includes a control assembly including pressure responsive valves (202, 204) which are operated sequentially by cams (268, 270). A pedal is suitably interconnected with the cams in such a manner that the clutch will be progressively disengaged as the pedal moves from an initial position towards its depressed position, the clutch pedal passing through a dwell position before the brake is progressively applied. The clutch will be fully disengaged when the pedal is in its dwell position, and as the transmission brake is applied there will be an increase in pedal effort.
