    摘要： A vehicle transaxle system includes a pair of right and left transaxle units equipped on a vehicle. The right transaxle unit supports a single right axle, and the left transaxle unit supports a single left axle. A variable displacement hydraulic pump is disposed in each of the right and left transaxle units so as to be driven by power from a prime mover of the vehicle. A variable displacement hydraulic motor is disposed in each of the right and left transaxle units and is fluidly connected to the corresponding hydraulic pump so as to drive the corresponding right or left axle. A movable motor displacement control member is provided in each of the transaxle unit so as to be moved to change the displacement of the corresponding hydraulic motor. An interlocking connection means is connected to both the movable motor displacement control members of the respective hydraulic motors. The vehicle is provided with a first manipulator for changing displacements of the hydraulic pumps, and is provided with a second manipulator for operating the interlocking connection means. The interlocking connection means is operated by operating the second manipulator so as to synchronously move both the movable motor displacement control members.

    摘要： A hydraulic drive vehicle includes a bypass valve for fluidly connecting or disconnecting a pump/second-motor line and a second-motor/first-motor line, and set a capacity of a first hydraulic motor to a standard capacity which makes a peripheral speed of a first wheel driven by the first hydraulic motor equal to a peripheral speed of a second wheel driven by a second hydraulic motor when the bypass valve fluidly disconnects the two lines and set the capacity of the first hydraulic motor to a first capacity smaller than the standard capacity when the bypass valve fluidly connects the two lines. The present invention makes it possible to widen a variable range in which a traveling speed of the vehicle could be changed.

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.
