Abstract
A control device 50 controls rotation of a first motor 21 and controls rotation of a second motor 22. In response to receiving a forward travel command from an operating device 51, the control device 50 controls rotation of the second motor 22 in such a manner that combined motive power output by a planetary gear mechanism 41 is used as forward motive power. In response to receiving a reverse travel command from the operating device 51, the control device 50 controls rotation of the first motor 21 in such a manner that the first motor 21 decelerates or stops, and controls rotation of the second motor 22 in such a manner that motive power output by the planetary gear mechanism 41 is used as reverse motive power.
Claims5
A work vehicle comprising:
- a first motor;
- a second motor;
- a transmission mechanism configured to transmit motive power from the first motor to a working power output section;
- a planetary gear mechanism configured to generate combined motive power by combining motive power received from the first motor with motive power received from the second motor, and output the combined motive power to a traveling power output section;
- a control device configured to control rotation of the first motor and control rotation of the second motor;
- and
- an operating device configured to issue a forward travel command and a reverse travel command to the control device, and
- wherein in response to receiving the forward travel command, the control device controlling rotation of the second motor in such a manner that the combined motive power output by the planetary gear mechanism is used as forward motive power, and
- wherein in response to receiving the reverse travel command, the control device (i) controlling rotation of the first motor in such a manner that the first motor decelerates or stops, and (ii) controlling rotation of the second motor in such a manner that motive power output by the planetary gear mechanism is used as reverse motive power.
