Abstract

A vehicle electric drive apparatus is provided with a single hydraulic pump and left-side and right-side drive units. The left-side drive unit includes a left-side electric motor and a left-side transmission mechanism. The right-side drive unit includes a right-side electric motor and a right-side transmission mechanism. One of rotary shafts of the left-side transmission mechanism and one of rotary shafts of the right-side transmission mechanism constitute a pair of pump-drive rotary shafts. The single hydraulic pump is connected to the pair of pump-drive rotary shafts through respective one-way clutches, and is to be driven by one of the pump-drive rotary shafts that is rotated at a speed higher than the other of the pump-drive rotary shafts, so as to output a hydraulic pressure.
