Problems solved by technology

[0008] However, in the electric vehicle described in Patent Document 1, since the oil from the mechanical hydraulic pump is directly supplied to the oil passage in the drive shaft, the heat dissipation of the oil is insufficient, and countermeasures such as installing an oil cooler separately are required.
In addition, the electric hydraulic pump does not describe the specific arrangement, and the oil cooled by the cooler is supplied to the travel motor.
In addition, the pump chamber of the mechanical hydraulic pump is composed of the partition wall of the casing and the pump cover, so there is still room for improvement in the assembly workability of the pump.

Embodiment Construction

[0146] The driving device for a vehicle of the present invention is a device in which an electric motor is used as a driving source for wheel driving, for example, in figure 1 used in vehicles with a drive system as shown. In the following description, a case where the vehicle driving device is used for driving the rear wheels will be described as an example, but it may also be used for driving the front wheels.

[0147] figure 1 The vehicle 3 shown is a hybrid vehicle having a driving device 6 (hereinafter referred to as a front-wheel drive device) in which an internal combustion engine 4 and an electric motor 5 are connected in series at the front of the vehicle. 7 is transmitted to the front wheel Wf, and on the other hand, the power of the driving device 1 (hereinafter referred to as the rear wheel driving device) provided at the rear of the vehicle separately from the front wheel driving device 6 is sent to the rear wheel Wr (RWr, LWr )transfer. Electric motor 5 of fro...

Abstract

A cooling conduit (120A) for a first electric motor and a lubricating conduit (121A) for the first electric motor supply oil from an electric oil pump (70) through the outer side of one end (E1) of the first electric motor (2A) to the portions (A1, A2) of the first electric motor (2A) which are to be cooled and lubricated. Also, a cooling conduit (120B) for a second electric motor and a lubricating conduit (121B) for the second electric motor supply oil from the electric oil pump (70) through the outer side of the other end (E2) of the second electric motor (2B) to the portions (B1, B2) of the second electric motor (2B) which are to be cooled and lubricated.

Description

technical field [0001] The present invention relates to a vehicle drive device, and more specifically, to a vehicle drive device that performs at least one of cooling, lubrication, and cooling and lubrication of an electric motor. Background technique [0002] As a conventional vehicle driving device, the electric vehicle described in Patent Document 1 discloses a vehicle driving device including a pair of electric motors on the left and right, and a mechanical hydraulic pump between the electric motors, Oil is supplied to the oil passage in the drive shaft to lubricate the torque transmission system, and a separately installed electric hydraulic pump cools the travel motor. In this mechanical hydraulic pump, a pump chamber for accommodating a rotating body is constituted by a partition wall of a casing and a pump cover, and is rotated by driving an electric motor.
