Abstract
An axially compact clutch and brake mechanism. Inner and outer concentrically mounted clutch and brake drums intermittently coupled respectively by packs of interleaved friction discs and plates are operated by a pressure plate disposed intermediate the clutch and brake disc and plate packs and responds to an annular hydraulic piston to alternately engage the clutch or engage the brake. Brake and clutch packs are axially spaced along the length of concentric input and output shafts while the piston is located radially inwardly of one of the packs and is not axially spaced therefrom so as to reduce the axial length of the assemblage. The mechanism further includes structure whereby the piston is not forced to rotate within its cylinder to thereby lengthen the life of the same.
