ABSTRACT:
A clutch brake is provided for a motor vehicle transmission clutch assembly having a brake disc within a rotatable transmission input shaft axially received within a central opening in the disc. The disc is connected to the input shaft for concurrent rotation therewith. The input shaft has a first end extending into a transmission housing member for connecting the input shaft to a transmission assembly, and an opposite second end extending into a clutch assembly for releasably connecting the input shaft to an adjacent engine crankshaft. A clutch housing member is connected to the clutch assembly which moves along the input shaft in an axial direction toward the transmission housing member during release of the clutch assembly from the input shaft. The brake disc is located along the input shaft between the transmission housing member and the clutch housing member. A clutch brake assembly is connected to the transmission housing member, the clutch brake assembly having a first caliper brake pad located on one rotational side of the disc and a second caliper brake pad located on an opposite rotational side of the disc. The first caliper brake pad is connected to an engagement member extending toward and being in engageable alignment with the clutch housing member. During movement of the clutch housing member toward the transmission housing member, the clutch housing member engages the engagement member of the first caliper brake pad so as to squeeze the disc between the first and second pads and thereby slow rotation of the disc.
