Vehicle drive device with two drive sources

摘要

A vehicle drive device has a reduction gear (G) is installed between first and second electric motors (M1 and M2) and a wheel axle (2) so that the first and second electric motors (M1 and M2) can transmit torque to the wheel axle (2) at different reduction ratios. More specifically, the reduction gear (G) is configured such that the torque of the first electric motor (M1) is delivered to the wheel axle (2) using a reduction ratio suitable for low speed travel and the torque of the second electric motor (M1) is delivered using a reduction ratio suitable for high speed travel. Thus, the vehicle drive device can deliver sufficient drive torque at rotational speeds ranging from low speeds to high speeds while preventing the size of the rotary drive source used to drive the vehicle from becoming large.
