Title:
DRIVING DEVICE OF HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/124184
Kind Code:
A1
Abstract:
Disclosed is a driving device of a hybrid vehicle, wherein the driving device transmits power from an engine (2) to an axle shaft (12) of a drive wheel (13), and the driving device also transmits power from an electric motor (16) to the axle shaft (12); an electric motor shaft (15) and an electric motor intermediate shaft (14) are arranged in parallel in a power transmission path from the electric motor (16) to the axle shaft (12); the electric motor shaft (15) is connected to a rotor shaft (16a) of the electric motor (16); the electric motor shaft (15) is provided with an electric motor shaft gear (15a), and the electric motor intermediate shaft (14) is provided with an electric motor intermediate shaft pinion (14a), an electric motor intermediate shaft large gear (14b) and a disconnection assembly (14c); the electric motor intermediate shaft pinion (14a) is engaged with a differential gear (11a) of a differential (11), and the differential (11) is connected to the axle shaft (12); the electric motor intermediate shaft large gear (14b) is engaged with the electric motor shaft gear (15a); and the disconnection assembly (14c) connects or disconnects the power transmission between the electric motor intermediate shaft large gear (14b) and the electric motor intermediate shaft pinion (14a). By means of the driving device of the hybrid vehicle, the loss of an electric motor during high-speed driving of the whole vehicle can be reduced, and the fuel consumption and power consumption of the whole vehicle are reduced.
