摘要： Two motors (12,14) are arranged on opposing sides of a common shaft (16), drive plates (30,32) of the pump/motors (12,14) being rigidly coupled to each other, for example by being in hard contact with opposing sides of the shaft (16). By providing hard contact between the pump/motor drive plates (30,32) and a common shaft (16), the drive plates and shaft act as a substantially solid element under compression, thereby substantially canceling axial loads generated by the pump/motors (12,14) directly through the shaft (16). Residual axial loads are handled via bearings (34,36) positioned on the shaft (16) adjacent the drive plates (30,32) in such a manner that the drive plates are in light contact only with the bearings (34,36). As a result, friction experienced by the bearings is substantially reduced as compared to conventional systems, thereby improving the efficiency of the system. To further reduce loads on the bearings (34,36), the pump/motors (12,14) are arranged to ensure that they generate radial forces in a direction that is opposite to that of a separation force generated by a torque transferring device carried on the shaft (16) and transmitted to the bearings (34,36). A common housing (17) surrounding the two pump/motors (12,14), bearings (34,36) and torque transferring device is divided into three regions, to segregate the bearings (34,36) and torque transferring assembly from the pump/motors (12,14). In this manner, the regions containing the pump/motors (12,14) are substantially filled with oil to, for example, fully lubricate the pump/motors (12,14), while the central region containing the gears and torque transferring device contains a significantly smaller volume of oil to simply splash lubricate the contents of the region, thereby reducing drag on the bearings (34,36). Control means are provided for selectively moving the two pump/motors (12,14) substantially simultaneously to a selected displacement angle, using mechanical systems alone and in combination with hydraulic systems.
摘要翻译：两个马达（12,14）布置在公共轴（16）的相对侧上，泵/马达（12,14）的驱动板（30,32）彼此刚性地联接，例如通过硬与轴（16）的相对侧接触。通过在泵/马达驱动板（30,32）和公共轴（16）之间提供硬接触，驱动板和轴在压缩下作为基本上实质的元件，从而基本上抵消由泵/马达产生的轴向载荷（ 12,14）直接穿过轴（16）。残余轴向载荷通过位于与驱动板（30,32）相邻的轴（16）上的轴承（34,36）以使得驱动板仅与轴承（34,36）轻微接触来处理。结果，与常规系统相比，轴承所经历的摩擦力显着降低，从而提高了系统的效率。为了进一步减少轴承（34,36）上的负载，泵/马达（12,14）被布置成确保它们产生径向力，其方向与由承载的扭矩传递装置产生的分离力的方向相反在轴（16）上并传递到轴承（34,36）。围绕两个泵/马达（12,14），轴承（34,36）和扭矩传递装置的公共壳体（17）被分成三个区域，以将轴承（34,36）和扭矩传递组件从泵 /电机（12,14）。以这种方式，包含泵/马达（12,14）的区域基本上充满油，以便例如完全润滑泵/马达（12,14），而包含齿轮和扭矩传递装置的中心区域包含显着更小的油体积，以简单地飞溅润滑该区域的内容物，从而减少轴承上的阻力（34,36）。提供控制装置，用于使用机械系统单独并与液压系统组合，将两个泵/马达（12,14）基本上同时地移动到选定的位移角。

摘要： A hydrostatic transmission system (10) for driving a rotatable member includes a differential (32) having an output (48) coupled with the rotatable member, a first hydrostatic drive (18) having an output (28) coupled to a first input of the differential (32), and a second hydrostatic drive (22) having an output (30) coupled to a second input of the differential (32). The output (28) of the first hydrostatic drive (18) is rotatable in a first selected direction and at a first selected speed. The output (30) of the second hydrostatic drive (22) is rotatable in a second selected direction and at a second selected speed. A rotational speed and direction of the output (48) of the differential (32) is related to the algebraic sum of the rotational speeds and directions of the outputs of the hydrostatic drives (18,22). In one embodiment, the speeds of the first and second drives (18,22) are maintained above a minimum stable threshold, while operating the rotatable drive at very low or zero speed, by selecting the first direction to be opposite the second direction.
