Title: Clutch disc with coaxial brake

Abstract: This specification discloses a transmission clutch brake for use in a torque delivery gear system. A rotatable clutch disc driven by an input shaft and selectively engageable by a pressure plate carries a pair of plates. The plates embrace a brake plate carrying friction material on opposite faces thereof. Upon disengagement of the pressure disc from the clutch plate one of said plates of said pair is moved axially relative to the other thereof in a clamping manner to grip the brake plate against rotation. The latter brake plate is connected to a stationary splined hub utilizing a snap ring. The ring acts as a torsion spring and permits limited slight rotation of the brake plate and clutch disc clamped thereto as well as the input shaft to facilitate meshing of gears of the transmission.
