Abstract

In the present invention, when a clutch is completely engaged, the supply of lubrication oil for an automatic transmission is ensured, and when performing slip control on the clutch when starting, a large flow volume of lubrication oil is provided to the clutch. When performing slip control on a clutch (6), an input port (25a) and an output port (25g) of a lubrication relay valve (25) are made to communicate with each other and the oil from a secondary oil pressure path (32) is provided directly to a clutch lubrication oil path (40), and when not performing slip control, the secondary oil pressure path (32) communicates with the clutch lubrication oil path (40) via an orifice (39). The communication ratio of a back face pressure port (23e) is adjusted using the oil pressure of the secondary oil pressure path (32), and oil on the back face pressure side is provided to parts (47) to be lubricated in the automatic transmission.

Description

technical field [0001] The present invention relates to a vehicle drive device having an engine cut-off (K0) clutch functioning as a starting clutch and an automatic transmission device, and is particularly suitable for use in a single-motor type hybrid drive device. The device is supplied with lubricating oil. Background technique [0002] In the past, a single-motor type that connected the output shaft (part) of the internal combustion engine to the input shaft (part) of the automatic transmission via the K0 clutch, and connected the rotor of the electric motor (rotary electric machine) to the automatic transmission was developed. Hybrid drive. Generally, the hybrid drive starts using the driving force of the electric motor, engages the K0 clutch at a predetermined low speed to start the engine, and uses the driving force of the engine to change the speed of the automatic transmission for running. At this time, the electric motor outputs to assist the driving force of th...
