Abstract

In the hybrid drive device according to the present invention, although the lubricating oil becomes high temperature due to the slip control of the clutch which is slipped when the internal combustion engine is started, the high temperature lubricating oil is prevented from flowing into the stator. Lubricating oil is supplied from the input shaft (7) to the clutch chamber (S), lubricates and cools the clutch (6), and flows out from the oil hole (47). The shielding parts (50, 51) provided on the casing (23) are located close to the front end of the cylindrical part (26a) of the rotor supporting member, and divide the space (A). Lubricating oil flowing out of the oil hole (47) into the space (A) is discharged from the discharge path (53) around the coil end (24a).

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...
