Abstract

The invention provides a drive device for a vehicle capable of reducing the number of components. A rear-wheel drive device (1) includes a first electric motor (2A) connected with a left rear wheel (LWr) in a manner capable of transmitting power, a first case (11L) accommodating the first electric motor (2A) and including a left reservoir (RL), a second electric motor (2B) connected with a right rear wheel (RWr) in a manner capable of transmitting power, a second case (11R) accommodating the second electric motor (2B) and including a right reservoir (RR), a first right-and-left communication passage (FP) via which the left reservoir RL and the right reservoir RR communicate with each other, wherein an oil sensor (80) is configured on the first right-and-left communication passage (FP).

Description

technical field [0001] The present invention relates to a vehicle drive device, and more specifically, to a vehicle drive device equipped with a sensor. Background technique [0002] As a conventional vehicle drive device, in the electric vehicle described in Patent Document 1, a pair of electric motors are provided on the left and right, and a first signal corresponding to the temperature of the oil stored in the oil pan of each electric motor is provided. And the second oil temperature sensor, the first and second oil level sensors that output signals corresponding to the oil level of the oil pan of each motor (refer to Patent Document 1 Figure 7 . ).
