摘要： A powertrain module (14) for a zero turn radius vehicle (10), such as a tractor or mower, the powertrain module generally including a structural member (24) or mounting plate to which an engine (30), a pair of hydrostatic transmission modules (26a, 26b), and a pair of axle drive units (28a, 28b) are attached to form a self-contained powertrain module which may be shipped as a single packaged unit for installation into the zero turn radius implement. The mounting plate provides structural rigidity between the powertrain components attached thereto, and the mounting plate of the powertrain module may be attached directly to the frame (12) of the vehicle, or alternatively, may itself serve as a structural frame member for the vehicle.

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.
摘要翻译：一种包括可变排量泵（56）的静液压传动装置（34,35），其包括输入轴（40）和可旋转地联接到所述输入轴的泵缸筒，所述泵缸筒具有多个与其它并分布在输入轴的旋转轴上。每个气缸室都具有一个往复运动的活塞，该往复运动的活塞靠在可枢转的斜盘上，泵的排量随斜盘位置的变化而变化。齿轮马达（66）附接到泵并具有输出轴（128）。电动机包括一对啮合的内部（120）和外部（118）构件，外部构件相对于内部构件是偏心的。内部构件通过从内部和外部构件之间接收的流体相对于外部构件旋转驱动，内部构件被驱动地连接到输出轴。多个流体管道（58,60）在泵到电动机之间延伸，电动机通过该泵与泵流体连通。
