VEHICLE DRIVE DEVICE

摘要

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.
