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 vehicle is installed with an integral transaxle apparatus constructed so that a single housing contains left and right axles, a driving hydrostatic transmission (HST) having a variable displacement first hydraulic pump and a first hydraulic motor fluidly connected with each other, a steering HST having a variable displacement second hydraulic pump and a variable displacement second hydraulic motor fluidly connected with each other, and a differential unit differentially connecting the axles with each other so as to be driven regularly or reversely by the output of the driving HST and to differentially drive the axles while receiving the output of the steering HST, wherein the first hydraulic pump receives power of a prime mover and has a first movable swash plate, and the second hydraulic pump receives power of the prime mover independently of the first hydraulic pump and has a second movable swash plate. The vehicle is also provided with driving operating means for slanting operation of the first movable swash plate for switching the travelling direction between forward and backward and for changing the travelling speed, and steering operating means for slanting operation of the second movable swash plate so as to determine the leftward and rightward cornering angle. The second 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 oppositely with respect to its neutral position according to the travelling direction switching operation of the driving operating means, whereby the vehicle turns laterally in the same direction of leftward and rightward steering operation of 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： There is provided a working vehicle having first and second hydraulic pump units operatively driven by a driving source and arranged away to each other in a width direction of the vehicle. In the working vehicle, each of the first and second hydraulic pump units includes a pump body; a port block formed with an oil passage for supplying/discharging an operating fluid to/from said pump body; a pump case connected to the port block so as to define a pump body accommodating space for surrounding the pump body; and a pump shaft for rotatably driving the pump body, the pump shaft having an input end operatively connected to said driving source. A drain port for opening the pump body accommodating space outward and a charge suction port for drawing in an oil from an oil tank in order to supply a charge oil to a hydraulic circuit fluidly connecting with the corresponding hydraulic motor unit are provided respectively in first and second assemblies formed by the corresponding pump case and port block. The drain port is provided on a wall surface other than an opposing wall surface facing each other of the wall surfaces of said first and second assemblies when arranging the first and second assemblies so that the input ends of each pump shaft are directed in the same direction.
