摘要： A vehicle including an integral transaxle apparatus with axles, a driving hydrostatic transmission (HST), a steering HST, and a differential unit. Driving operating means for slanting operation of a first movable swash plate of the variable displacement driving hydraulic pump for switching the travelling direction between forward and backward and for changing the travelling speed, and steering operating means for slanting operation of a second movable swash plate of the variable displacement steering hydraulic pump so as to determine the leftward and rightward cornering angle are provided. The steering hydraulic motor has a third movable swash plate interlocking with the driving operating means so that the slanting direction of the third movable swash plate is changed according to the operation of the driving operating means, whereby the vehicle turns laterally in the same direction in response to the steering operating means whether the vehicle travels forward or backward.

摘要： A transaxle apparatus is constructed so that left and right axles, two hydrostatic transmissions (HSTs), one for driving a vehicle and the other for steering it, and a differential unit for differentially connecting said axles with each other are together contained in a housing. The driving HST is disposed so that its hydraulic pump and motor are aligned along either a left or right side of the housing. The steering HST is disposed so that its hydraulic pump and motor are aligned along either a front or rear side of the housing. The differential unit is laterally opposite to the driving HST. Either the left or right axle crosses the driving HST between its hydraulic pump and motor. The two HSTs are provided with one or two flat center sections disposed in the housing. The cylinder blocks of the hydraulic pumps and motors of the two HSTs are mounted on either a top or bottom surface of the center section or sections. Power transmission mechanisms for transmitting output power from the hydraulic motors of the two HSTs into the differential unit are disposed on an opposite side of the center section(s) as the cylinder blocks. A charge pump may be attached onto the center section, and a conduit for sending fluid discharged from the charged pump into one or both HSTs may be partly extended outside the housing so as to be cooled by the atmosphere.

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 charge pump for a hydrostatic transmission, having a self-charge relief function, in which a first toothed wheel, a second toothed wheel, and a pump casing, housing therein the first and second toothed wheels, are molded of heat resistant resin material, thereby reducing the weight of the charge pump, stabilizing its charge relief function and reducing the wear of the lower surface of a center section. Check valves are housed in the pump casing so that operating oil sealed between a hydraulic pump and a hydraulic motor can always be maintained at a proper level, regardless of whether the charge pump is driven or not.

摘要： A hydrostatic transmission and a charge pump for supplying operating oil which are housed in a housing, in which a pump casing of the charge pump is mounted to a center section of the hydrostatic transmission without using mounting bolts. A spring is interposed between the pump casing and the inner surface of the housing. For defining pump discharge pressure, the center section receives all of the radial force generated in the pump casing. Between the center section and the charge pump is interposed a plate of material made of less friction resistance so as to reduce the sliding resistance. The charge pump is simple in construction and inexpensive to produce.
