摘要： A drive module for a hydraulic hybrid vehicle includes two variable displacement over-center bent-axis hydraulic pump/motors with respective yokes that reside and pivot within a common fluid-filled case. The cylinder barrel of each pump/motor is connected to high pressure through fluid-conducting yoke legs, and is connected to low pressure through the fluid-filled case, which is connected by a port to a low pressure source. As a drivetrain for a vehicle, one pump/motor acts primarily as a pump driven by an engine and the other pump/motor acts primarily as a motor to propel the vehicle. A removable support structure facilitates installation to a variety of vehicle chassis.

摘要： A power-branched transmission, particularly for agricultural vehicles such as tractors or similar, includes a stepped planetary gear which is disposed between an input shaft and an output shaft and is used for dividing the power supplied at the input shaft onto a mechanical power branch and a hydraulic power branch. The hydraulic power branch is formed by two hydraulically interconnected, identical hydrostatic axial piston engines which can be selectively operated as a pump or an engine, can be swiveled within a predefined pivoting angle, and can be connected to the input shaft or the stepped planetary gear in a different manner via two respective clutches so as to cover different operating ranges or running steps. In order to obtain better efficiency in such a power-branched transmission, the two hydrostatic axial piston engines are configured as wide-angle hydrostats that are provided with a minimum pivoting angle range of 45°.

摘要： Two motors are arranged on opposing sides of a common shaft, drive plates of the pump/motors being rigidly coupled to each other, for example by being in hard contact with opposing sides of the shaft. By providing hard contact between the pump/motor drive plates and a common shaft, the drive plates and shaft act as a substantially solid element under compression, thereby substantially canceling axial loads generated by the pump/motors directly through the shaft. Residual axial loads are handled via bearings positioned on the shaft adjacent the drive plates in such a manner that the drive plates are in light contact only with the bearings. 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, the pump/motors 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 and transmitted to the bearings. A common housing surrounding the two pump/motors, bearings and torque transferring device is divided into three regions, to segregate the bearings and torque transferring assembly from the pump/motors. In this manner, the regions containing the pump/motors are substantially filled with oil to, for example, fully lubricate the pump/motors, 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. Control means are provided for selectively moving the two pump/motors substantially simultaneously to a selected displacement angle, using mechanical systems alone and in combination with hydraulic systems.
摘要翻译：两个电动机布置在公共轴的相对侧上，例如通过与轴的相对侧硬接触，泵/电动机的驱动板彼此刚性地联接。通过在泵/马达驱动板和公共轴之间提供硬接触，驱动板和轴作为压缩下的基本上实心的元件，从而基本上消除了泵/马达直接通过轴产生的轴向载荷。残余轴向载荷通过位于与驱动板相邻的轴上的轴承来处理，使得驱动板仅与轴承轻微接触。结果，与常规系统相比，轴承所经历的摩擦力大大降低，从而提高了系统的效率。为了进一步减少轴承上的负载，泵/电动机被布置成确保它们产生径向力，该方向与由承载在轴上并传递到轴承的转矩传递装置产生的分离力的方向相反。围绕两个泵/马达，轴承和扭矩传递装置的共同壳体被分为三个区域，以将轴承和扭矩传递组件与泵/马达隔离。以这种方式，包含泵/马达的区域基本上填充有油，以例如完全润滑泵/马达，而包含齿轮和扭矩传递装置的中心区域包含明显较小体积的油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。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/马达基本上同时地移动到选定的位移角。

摘要： The invention relates to a hydraulic module for hydrostatic mechanical gearboxes having two swashplates or oblique axis drive units which are integrated in the hydraulic module. The swashplate drive units are mounted in a common housing with parallel drive shafts and each have a rotating cylinder block with expellers which can move therein and which are supported in a sliding fashion on a double swashplate whose pivot angle is adjustable by means of a servo system. The double swashplate is designed to carry out positively coupled common adjustment of the volume flow of the two drive units and is equipped with bearing faces for the expellers of the respective drive units, said bearing faces having different angles of inclination relative to the respective drive shaft. The oblique axis drive units each have a cylinder block with expellers which can move therein and which are each pivotably mounted on the coaxial shafts.

摘要： A hydrostatic module is disclosed, including a pair of shafts rotatably supported by a frame. Two yokes are pivotally mounted on the frame, each having complimentary surfaces to the other yoke and to the frame, minimizing the space occupied by the yokes. Stop means are provided on the yokes and on the frame to limit the pivotal movement of the yokes. A hydrostatic power unit is carried by each yoke, each connected to one of the shafts. A control system, having a single piece control housing containing servo pistons, pivots the yokes. The servo pistons independently determine the orientation of the yokes. A single piece fluid control porting plate is secured to the control housing to route hydraulic fluid to multiple locations within the control housing. A fluid manifold serves as a main structural element, with intimate proximity between the manifold and the control housing allowing simplified fluid exchange therebetween.

摘要： A vehicle drive-train includes a drive-motor having an output shaft and a transmission having an input shaft, an output shaft, a plurality of discrete forward gear ratios and a corresponding plurality of synchronizers. Each of the synchronizers is configured to mechanically synchronize rotation of the drive-motor output shaft with the transmission output shaft according to a value of a selected gear ratio, during shifting of the transmission to the selected gear ratio. The output shaft of the drive-motor and the input shaft of the transmission are coupled together such that, during normal operation of the drive-train, rotation of the output shaft of the drive-motor results in a proportionate and uninterrupted rotation of the input shaft of the transmission.
