HYBRID DRIVE MODULE
Document Type and Number:
WIPO Patent Application WO/2021/118054
Kind Code:
A1
Abstract:
Disclosed is a hybrid drive module A hybrid drive module according to an embodiment of the present invention is for selectively transmitting rotational power transmitted from an engine and a motor to a transmission, the hybrid drive module comprising: a housing disposed between the engine and the transmission; a drive shaft which is rotatably mounted inside the housing in a radial direction with one end facing the engine on the basis of an axial direction while protruding from the housing, and to which rotational power of the engine is inputted; a rotor hub which is provided inside the housing, is equipped with a rotor of the motor on the radially outer side thereof, extends integrally toward the drive shaft on the radially inner side thereof, and has a hub plate part rotatably connected to the other end of the drive shaft facing the transmission on the basis of the axial direction; a rotor hub ridge of which the inner circumferential surface is rotatably supported on the housing on the basis of the radial direction, and of which the outer circumferential surface is fixed to the rotor hub from the engine side on the basis of the axial direction; an engine clutch which is disposed on the engine side in the axial direction with the hub plate part interposed therebetween, and which directly connects the drive shaft and the rotor hub so as to selectively transmit the rotational power of the engine to the rotor hub; and a torque converter which is disposed on the transmission side in the axial direction to be connected to the rotor hub, the hub plate part being interposed therebetween , and which multiplies or transmits the rotational power of the engine, the motor, or the engine and the motor to the transmission in a 1:1 ratio when a vehicle is initially driven, wherein the hub plate part may have, on one surface thereof facing the engine clutch, at least one fluid groove for cooling by means of supplying a working fluid to the rotor between the engine clutch and the hub plate part on the basis of the axial direction.
