摘要： A travel control unit of a working vehicle includes an HST which is a hydraulic continuously variable transmission having a hydraulic pump and a hydraulic motor, a pedal sensor which is an operator sensor which detects a position of an acceleration pedal which is an acceleration operator, and a controller which changes a displacement of the hydraulic pump based on the position of the acceleration pedal. The controller increases the displacement of the hydraulic motor as the displacement of the hydraulic pump is reduced due to a displacement of the acceleration pedal to a low-velocity side.

摘要： In the hydraulic actuator unit according to the present invention, a first electric motor assembly formed by mounting one of a pair of electric motors to one of a pair of electric motor covers is detachably mounted to a pump case so as to rotate a first control shaft around its axis line, and a second electric motor assembly formed by mounting the other one of the pair of electric motors to the other one of the pair of electric motor covers is detachably mounted to the pump case so as to rotate a second control shaft around its axis line. The first electric motor assembly is mounted to the pump case so that the corresponding electric motor has a rotational axis line in parallel with the first pump shaft in a state where the electric motor is positioned on an opposite side to the second control shaft with respect to the first control shaft and is also positioned on an opposite side to a first end of a first pump shaft with respect to a virtual plane that passes through the axis lines of the first and second control shafts. The second electric motor assembly is mounted to the pump case at a posture obtained by rotating the first electric motor assembly by 180 degrees about a virtual center line that is disposed in parallel with the first and second control shafts and is located at a center between the first and second control shafts, thereby the electric motor is positioned on an opposite side to a cooling fan, which is driven by the second end of the second pump shaft, with respect to the virtual plane.

摘要： A hydrostatic stepless transmission ("HST") includes a center casing into which a plunger block of a hydraulic pump and a plunger block of a hydraulic motor are inserted. Plunger ports are open and aligned peripherally on an outer peripheral surface of each plunger block. A pair of main fluid passages of a closed fluid circuit fluidly connecting the hydraulic pump to the hydraulic motor are formed in opposite side portions of the center casing. Each of the main fluid passage includes peripheral grooves formed on an inner peripheral surface of the center casing so as to face the plunger ports of the respective plunger blocks, and includes an axial fluid duct formed to be interposed between the peripheral grooves. A bearing gap is provided between the inner peripheral surface of the center casing and the outer peripheral surface of the plunger block so as to cause a dynamic pressure action of fluid.
