Abstract
A torque-limiting clutch brake is provided that has an inner collar which splines to a transmission gearbox input shaft. An intermediate coupling member fits around and engages the inner collar. A friction generating resilient wave washer is disposed between the intermediate coupling member and an outer housing. The outer housing includes two covers, within which the components are contained and the resilient wave washer is partially compressed. Friction generated by the resilient wave washer conditionally couples the outer housing to the intermediate coupling member and inner collar until torque on the device exceeds a certain threshold, at which point the clutch brake slips to prevent damage. The components are made up of separable semicircular sections which can be split apart to facilitate removal and installation of the clutch brake without lowering and disassembling the vehicle transmission. The outer housing is hinged at one end and has a clamping bolt at the other end for securing the unit around a gear box input shaft.
