摘要： A modular hydrostatic transaxle (8) includes an axle module (12) removably connected to a hydrostatic transmission module (10). The axle module includes a differential connected to a reduction gear train and disposed in an axle casing (18). A pair of axles (20, 22) are connected to the differential and supported within the axle casing. The hydrostatic transmission module (10) comprises a transmission casing (78) separate from the axle casing (18) and hydraulically connected pump (169) and motor (138) disposed in the transmission casing. The motor output connection includes a shaft (26) piloted to an input drive (32) of the reduction gear train, which constitutes the alignment mechanism of the transmission and axle modules. The pump and motor cylinder barrels (116, 140) are hydraulically connected through the pump and motor block (90) at 90°orientation, and a portion of the pump and motor block forms an inclined surface (184) which supports a face of a thrust bearing (186). At least one homogeneous low friction bearing strip (216) is confined between the swash plate (130) and the interior portion of the casing. A disconnect mechanism (30) includes a spring (212) that urges a sleeve to engage the output and input shafts. The brake disc (64) is disposed on a distal end of the output shaft and a brake cover (74) is fastened to the outer portion of the axle casing and substantially encloses the brake disc.

摘要： A hydrostatic transmission (34, 35) including a variable displacement pump (56) including an input shaft (40) and a pump cylinder barrel rotatably coupled to the input shaft, the pump cylinder barrel having a plurality of cylinder chambers arranged in parallel with other and distributed about the input shaft axis of rotation. Each cylinder chamber has a reciprocating piston therein which bears against a pivotable swashplate, the displacement of the pump being varied in response to changes in the position of the swashplate. A gerotor motor (66) is attached to the pump and has an output shaft (128). The motor includes an engaged pair of inner (120) and outer (118) members, the outer member being eccentric relative to the inner member. The inner member is rotatably driven relative to the outer member by fluid received between the inner and outer members from the pump, the inner member being drivingly connected to the output shaft. A plurality of fluid conduits (58, 60) extend between the pump to the motor, through which the motor is in fluid communication with the pump.

摘要： A walk-behind self-propelled implement (20a, 20b, 20c), such as a snow thrower (20a, 20b) or lawnmower (20c), for example, is provided. The implement includes first and second transmission modules (128, 130) associated with a common single axle (142) to which a pair of drive wheels (24a, 24b, 24c) is attached. The first and second transmission modules are operable exclusively with respect to one another to drive the axle and the wheels in a forward and reverse direction, respectively. A control member (262) mounted to the handle (30) of the implement includes a forward bail member (264) pivotable to rotate the control member in a first direction to urge the wheel to rotate in a forward direction, and a reverse bail member (266) pivotable to rotate the control member in a second direction opposite the first direction to urge the wheel to rotate in a reverse direction.
