摘要： A bent axis hydromodule that utilizes a bearing carrier assembly between the trunnion of a yoke and the frame of the bent axis hydromodule. The bearing carrier receives the trunnion and is secured to the frame by at least one fastening element that extends axially perpendicular to the trunnion axis that causes the fastening element preload force to be in the same direction as primary loading of that joint.

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 variable displacement bent axis hydraulic unit includes a control mechanism having a control housing with a displacement feedback sleeve and spool connected by a spring. A computer controls a proportional solenoid fluid valve that is in operative fluid engagement with the end of the spool opposite its spring connection with the displacement feedback sleeve. The displacement feedback sleeve is urged by the spring into engagement with a cam member on the yoke of the bent axis unit.

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 special ball joint for servo piston actuation in a bent axis unit includes an elongated actuator rod having a substantially spherical external surface on a first end and a servo piston on a second end. Also included is a single-piece yoke adapted to carry a cylinder block and rotate about an axis of rotation. A socket having a substantially spherical surface is interposed between the yoke and the spherical surface on the rod such that the actuator rod rotates the yoke with forces residing in at least two planes when hydraulic pressure is applied to the servo piston. Two servo pistons and two such ball joints can be applied to the yoke to obtain rotation of the yoke which is up to greater than plus or minus 45° from a neutral position. The external surface on the first end of the actuator rod and the socket must be mating so as to provide freedom of movement. The socket can be incorporated into the yoke itself. The foregoing servo pistons are received in servo bores of a one-piece control housing. An integral cam is formed in a control trunnion to accommodate the swinging movement of the yoke.
