Abstract
A work vehicle such as a tractor including an engine, a battery, a hydraulic continuously variable transmission, and an electric cylinder, and a power transmission mechanism. The hydraulic continuously variable transmission changes an output of the engine, and changes an angle of a movable swash plate to change a gear ratio thereof. The electric cylinder is driven by electric power supplied from the battery at least while the engine is stopped. With the power generated in the electric cylinder and transmitted, the power transmission mechanism changes the angle of the movable swash plate of the hydraulic continuously variable transmission.
Claims7
A work vehicle comprising:
- a hydraulic continuously variable transmission including an arm configured to change an inclination angle of a movable swash plate to change a gear ratio;
- an actuator configured to generate power for to enable movement of the arm;
- and
- an inclination angle detection unit configured to detect the inclination angle of the movable swash plate, at least a part of the inclination angle detection unit being disposed higher than a height of a center of a rear axle of a rear wheel.
