ABSTRACT:
A friction-type clutch assembly is provided for connecting full-speed power to a dead load, including an output shaft assembly including axially spaced, annular separator plates extending outwardly from and slidably secured along their inner circumference directly to an output shaft hub, a drive gear assembly including axially spaced, annular friction plates extending inwardly from and slidably secured along their outer circumference directly to an outer carrier member, with the annular friction plates of the drive gear assembly interposed between the annular separator plates of the output shaft assembly so that lateral motion of the respective plates toward one another causes clutching action of the drive gear and output shaft, and a piston and cylinder arrangement for drivingly connecting the drive gear assembly to the output shaft assembly, including an annular piston rotatably mounted on the output shaft and interposed between the drive gear and the output shaft hub, with the outer piston face being annular and disposed to directly engage the innermost one of the separator plates when the clutch is actuated without any intervening element therebetween, a coil spring for normally maintaining the piston disengaged from the innermost separator plate, with the coil spring surrounding the output shaft and disposed within a recess within the piston, and with the inner piston face cooperating with the outer face of the drive gear to define therebetween a chamber for hydraulic fluid under pressure.
