Abstract
A power-dividing device for a working vehicle includes a case member, an input shaft supported by the case member so that a first end portion of the input shaft can be operatively connected to a driving source, a PTO unit having a PTO shaft supported by the case member so as to be offset with respect to the input shaft, a power transmission mechanism accommodated in the case member to transmit power from the input shaft to the PTO shaft, and a first pump unit having a first pump shaft operatively connected to the input shaft and being fluid-connected to an actuator disposed outside.
Claims11
A power-dividing device for a working vehicle, comprising:
- a case member;
- an input shaft supported by the case member so that a first end portion of the input shaft can be operatively connected to a driving source;
- a PTO unit having a PTO shaft supported by the case member so as to be parallel and offset with respect to the input shaft;
- a power transmission mechanism accommodated in the case member to transmit power from the input shaft to the PTO shaft;
- and
- a first hydraulic pump unit which has a first pump shaft arranged parallel to the input shaft and a first pump body driven by the first pump shaft, the first hydraulic pump unit being connected to the case member, wherein
- the first hydraulic pump unit is fluidly-connectable to an actuator through external conduits, the actuator being disposed away from the case member so as to drive a pair of drive wheels;
- and
- the power transmission from the input shaft to the first pump shaft is performed via the power transmission mechanism.

- wherein
- the input shaft is disposed along a vehicle back and forth direction, and
- the first pump unit and the second pump unit are coupled to the same side of the case member in the vehicle back and forth direction.
