Abstract

The motor cooling system circulates cooling oil for cooling a motor. A transmission is configured to change a rotation speed ratio of an output shaft with respect to an input shaft by changing a rotation speed of the motor. A transmission case has an output shaft case for housing the output shaft. The output shaft case is positioned forward of the motor and protrudes to a position below the motor. The motor cooling system has a cooling oil tank for storing the cooling oil and a cooling oil pipe which connects a cooling oil tank and the motor. The cooling oil tank is positioned behind the output shaft case and under the motor.
