    摘要： A hydrostatically power-splitting transmission (10), particularly for agricultural and construction equipment, comprises at least two hydrostats (H2), which are hydraulically connected to each other and operate as pumps or as motors, wherein at least one of the hydrostats (H2) can be adjusted or pivoted by means of a controller (16, 20, 21; SK1, . . . SK4), mechanical coupling means (K1, K2; Z1, . . . , Z12), which couple the hydrostats (H1, H2) to an inner drive shaft (W1) and an inner driven shaft (W7), a housing (14, 31) comprising a cover (14) and a housing bottom part (31), wherein the hydrostats (H1, H2), the inner drive and driven shafts (W1, W7), and the mechanical coupling means (Z7, Z9) are disposed and attached on the bottom of the cover (14), and in the lower housing part an outer drive shaft accessible from the outside and a driven shaft are supported, which are operatively connected to the inner drive shaft or driven shaft when the housing is assembled. In such a transmission, a compact design, while simultaneously providing easy accessibility and high flexibility in the adaptation to different vehicles, is achieved in that the controller (16, 20, 21; SK1, . . . SK4) for adjustment or pivoting of the at least one hydrostat (H2) is disposed on the top of the cover (14) and acts upon the at least one hydrostat (H2) through the cover (14).

    摘要： The invention relates to a hydrostatic transmission having two bent axis- or swashplate-type axial piston units which are operated alternately as a pump and as a motor, with the two axial piston units being adjustable together with a pivotable dual yoke or by means of a pivotable dual swashplate. In order to minimize the dead volumes of the two axial piston units, the rotational axes of the two axial piston power units are offset with respect to the pivot axis of the dual yoke or of the swashplate by a magnitude such that, at all pivot angles, the power unit pistons, at dead centre, are located in the direct vicinity of the bore end of the cylinder block.

    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 hydrostatic unit for a hydro-mechanical torque division transmission for a work vehicle having a mounting frame (10, 12) in which the shafts (18, 20) of hydrostatic devices (22, 24) are arranged parallel to one another are supported by bearing units (14, 16, 42, 48). The mounting frame (10, 12), the hydrostatic units (22, 24), the input shaft (36), the output shafts (44, 50, 56, 64) and the bearing units (14, 16, 42, 48, 54) together form a functioning hydrostatic module which can be pre-assembled. By supporting an input shaft (36) of the hydrostatic unit on the mounting frame (10, 12) by a bearing unit (38) such that it can rotate and is connected to the shaft (18) of the pump (22), a hydrostatic unit is provided that can be used in many different transmission applications.

    摘要： A parallel hydromechanical continuously variable transmission has a housing that holds a make-up pump, and has internal cavities for holding operating assemblies of the transmission, including an axial piston pump and an axial piston motor. The pump and motor each have a rotating element and a non-rotating element. Each rotating element has a center of mass and an axis of rotation that passes through the center of mass. Each non-rotating pump element is mounted for tilting movement on trunnions in its own respective pair of mounting journals in the housing. The tilting axes of the non-rotating elements lie transverse to the axes of rotation of the rotating element. The pump and the motor are disposed side-by-side in the housing with the axes of rotation approximately parallel to each other. A stationary manifold, fixed to the housing, has one surface in contact with the rotating pump element and a second surface in contact with the rotating motor element. Fluid passages open in the two surfaces in fluid communication with the pump and motor cylinders through a pump/manifold interface. Internal fluid passages in the stationary manifold convey fluid pressurized in the pump directly to the motor, and convey spent fluid displaced from the motor back to the pump. The transmission ratio is controlled by the tilt angle of the non-rotating pump and motor elements. A tilt angle control apparatus attached to the housing and to the non-rotating pump and motor elements governs that tilt angle.
