Abstract
A pump (10) is disclosed including an integral clutch and including a housing (26) divided into a clutch zone and a pump zone by a dividing wall (58). An input shaft (12) including a clutch spider (16) is rotatably mounted by a ball roller bearing (54) to a clutch end plate (50). An output shaft (14) is rotatably mounted by linear roller bearings (62, 76) to a pump end plate (68) and the dividing wall (58). A disk pack (20) is slideably mounted to the clutch spider (16) and the output shaft (14) and sandwiched by a piston (34) moved by fluid pressure outward relative to a pressure cylinder (36) and against a pressure plate (28) removably connected to the axial end of the output shaft (14). Thus, axial clutch actuation loads are transmitted only through the disk pack (20) and not to any of the bearings (54, 62, 76). The free axially outer end of the output shaft (14) extends through the pump zone and is located in the pump end plate (68). Clutch actuation fluid is communicated without bearings by first and second passages (96) extending from the pressure cylinder (36) and intersecting with an axial bore (94) in the output shaft (14) into which fluid is introduced by a rotary union (…
