摘要： A hydrostatic variator having a common yoke design and two or more bent axis piston drive units is disclosed in which the rotating group of a drive unit is arranged to be movable relative to the yoke to alter the angle between its drive shaft axis and rotating group axis independent of the other drive unit. This can be accomplished using movable sector plates coupled to the rotating groups that are arcuately movable within the yoke about the axis perpendicular to the respective drive shaft axes of the drive units. Such variators enjoy the response and packaging advantages of a common yoke design while still allowing dynamic adjustment of system size. In turn, varying system size allows for efficiency to be improved at conditions other than at the maximum design torque.

摘要： A hydraulic transmission has a pump and a hydraulic motor which are in communication with each other through a fluid passage and each of which has an eccentric or inclined movable member that is moved to vary the volume of liquid discharged by the pump or motor, the pump receiving an input rotation that is developed from the motor as an output rotation of a varied rotational frequency. The hydraulic transmission further includes a first element for urging the movable member of the pump in a first direction, a second element for urging the movable member of the motor in a second direction; and an actuating mechanism which moves the movable member of the pump a distance proportional to a control input, and which, when the displacement of the pump is varied, retains the movable member of the motor to keep the displacement of the motor constant, and which, when the movable member of the pump is retained at a certain position, moves the movable member of the motor a distance proportional to the control input.

摘要： An axle driving apparatus in which a hydraulic pump and a hydraulic motor which constitute a hydrostatic transmission are disposed on a center section. In a horizontal portion of the center section are provided a pair of linear oil passages in parallel to each other. A pair of arcuate ports are provided on a pump mounting surface formed on the horizontal portion of the center section. The pair of arcuate ports are substantially perpendicular with respect to the direction in which the oil passages extend. The axis of slanting movement of a movable swash plate of the hydraulic pump extends laterally of the vehicle body on which the axle driving apparatus is provided. The rotating direction of an arm provided on a control shaft for slantingly operating the movable swash plate is coincident with the operating direction of a control rod connected with a speed changing member. Thus, the link mechanism for connecting the speed changing member and the control arm for the movable swash plate is simplified.

摘要： A hydrostatic transmission is disclosed comprising a radial ball pump (11) and a radial ball motor (13) wherein the normal journal member (33) may be replaced by an alternative or modified journal member (33'), such that even with a reverse direction of actuation of the displacement control (49), the HST still operates in the forward direction, with no other changes required. The present invention also includes a simplified dump valve member (107) comprising a single, unitary member which may be merely inserted to its assembled position in which a pair of retention portions (123, 135) retain the dump valve, and permit it to pivot about the retention portions from an unactuated position to an actuated position.

摘要： A hydromechanical power transmission system is disclosed, including a positive-displacement variable-speed piston-type hydrostatic power transmission driven by an input shaft and a coordinating planetary gear train connected to an output shaft. The hydrostatic transmission is made up of a variabledisplacement unit connected to the input shaft and usually acting as a pump and a constant-displacement unit positioned in series with the variable-displacement unit and usually acting as a hydraulic motor. A portion of the power input is transmitted to the output shaft through the hydrostatic transmission and the remaining portion is transmitted by the planetary gear train as a mechanical transmission unit so that the power transmission efficiency is higher than that attained in the conventional hydrostatic power transmission which is void of such mechanical transmission unit. A typical application of such transmission system is an automotive vehicle.
