Abstract
A hydraulic clutch and a speed reducing planetary gear train, with an assembly comprising a fixed feeder block, a rotating crankcase integral with a feeder sleeve receiving at least a piston, a so-called closure wall and at least a set of friction discs for driving at least an output hub and a speed reducing planetary gear train, and a including a ring gear designed to be driven by an input shaft, a fixed axle pinion, and a planet pinion cage. The closure wall is made integral in rotation with the feeder sleeve and the crankcase and directly driven by the planet pinion cage.
Claims14
An integrated assembly comprising a hydraulic clutch and a speed reducing planetary gear set, said assembly including, a stationary oil supply bush, a rotating casing integral with an oil supply sleeve, receiving at least one piston,an end partition and at least one set of friction discs for driving at least one friction hub, said assembly also including a speed reducing planetary gear set having a ring gear to be driven by an input shaft, a stationary sun gear and planet pinion carrier, the end partition being fixed for rotation with the oil supply sleeve and with the casing and being driven directly by the planet pinion carrier, the end partition and the piston defining a centrifugal compensation chamber therebetween.
An automatic transmission including an integrated assembly comprising a hydraulic clutch and a speed reducing planetary gear set, said assembly including, a stationary oil supply bush, a rotating casing integral with an oil supply sleeve, receiving at least one piston an end partition and at least one set of friction discs for driving at least one friction hub and said assembly also including a speed reducing planetary gear set having a ring gear to be driven by an input shaft, a stationary sun gear and planet pinion carrier, the end partition being fixed for rotation with the oil supply sleeve and with the casing and being driven directly by the planet pinion carrier.
