Abstract

The invention discloses a hybrid drive device, comprising a shell, a dual clutch, a first input shaft, a second input shaft, an electric motor input shaft, a first output shaft, a second output shaft, a chain wheel shaft and a shifting clutch. The hybrid drive device can realize the hybrid drive mode, the pure electric drive mode and the engine drive mode, to provide the reverse gear for the engine drive mode without increasing a reverse gear shaft and a reverse gear idle gear, so that the engine can realize the reverse gear when the battery is low in electric quantity or the electric motor breaks down, and the working reliability of a hybrid electric vehicle is improved on the premise of guaranteeing the structure compactness.

Description

technical field [0001] The invention relates to the field of hybrid drives, in particular to a hybrid drive device. Background technique [0002] At present, there are mainly two types of hybrid drive devices. One is the planetary gear transmission scheme, which connects the engine and the motor through a planetary row structure to realize the coupling and speed regulation of the output torque of the engine and the motor. The second is the multi-speed transmission scheme, which connects the engine with the multi-speed transmission, the mode switching clutch and the motor in turn, and completes the mode switching and torque coupling and adjustment of the hybrid device through the gear switching of the multi-speed transmission and the action of the mode switching clutch. speed. [0003] The planetary gear transmission scheme is limited by the speed ratio, and there will be insufficient power, especially when working in pure electric mode, it cannot meet the requirements of po...
