摘要： A bent axis hydrostatic module, comprising: a frame, a pair of parallel laterally spaced shafts rotatably supported by the frame and directed outwardly from the frame in the same direction. Two yokes are pivotally mounted about parallel axes on the frame. A hydrostatic power unit is swingably carried by each yoke, and each hydrostatic power unit being operatively connected to one of the shafts to rotate the same. A pair of system pressure conduits in the frame with each of the pressure conduits are fluidly connected to each of the cylinder blocks. A control system is provided for pivoting the yokes including means for independently pivoting the yokes about parallel axes.

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.
摘要翻译：公开了一种静液压模块，包括由框架可旋转地支撑的一对轴。两个轭架可枢转地安装在框架上，每个轭架具有与另一个轭架和框架互补的表面，从而最小化轭架占据的空间。在轭和框架上提供止动装置以限制轭的枢转运动。静液压动力单元由每个轭承载，每个轭连接到一个轴。具有包含伺服活塞的单件控制壳体的控制系统枢转轭架。伺服活塞独立地确定轭的方向。单件流体控制移植板固定到控制壳体以将液压流体路由到控制壳体内的多个位置。流体歧管用作主要结构元件，在歧管和控制壳体之间紧密接近，允许简化在其间的流体交换。
