Abstract

This hybrid drive device separates the lubricant supplied to a clutch and to an electric motor and improves lubrication and cooling of the clutch and electric motor. Lubricant from a clutch lubrication hole (143) and an electric motor lubrication hole (145) and consisting of shaft core lubrication is partitioned by a rotor support member (126). The lubricant which lubricates the clutch (6) and flows out is separated by the cover member (187) and does not flow into the coil end (24a) on one side. The electric motor lubricant is guided to the coil end (24b) on the other side, and, passing through an oil passage (186), is guided to the coil end (24a) on the first side.

Description

technical field [0001] The present invention relates to a hybrid drive device having an internal combustion engine and an electric motor (rotary electric machine) as drive sources, and specifically relates to a single-motor type hybrid drive that disconnects the engine and transmits power from the internal combustion engine to an automatic transmission via a (K0) clutch Circulation of lubricating (cooling) oil in the drive unit. Background technique [0002] Conventionally, a single-motor type hybrid drive device has been proposed in which an output shaft (part) of an internal combustion engine is connected to an input shaft (part) of an automatic transmission via a K0 clutch, and a rotor of an electric motor is connected to an automatic transmission. device connection. 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 shift the...
