Abstract

The invention relates to the field of vehicle hybrid power and discloses a double-motor hybrid power drive device which comprises an engine, a double-motor power module and a double-input-shaft speedchanger. The double-motor power module comprises a shell, a first motor, a second motor, a first transmission assembly and a second transmission assembly. The double-input-shaft speed changer comprises a first input shaft, a second input shaft and a transmission device. The engine is connected with the first motor through the first transmission assembly. The power output end after the engine is mixed with the first motor is connected with the first input shaft, and power is transmitted to a car wheel through the transmission device. The second motor is connected with the second input shaft through the second transmission assembly, and the power is transmitted to the car wheel through the transmission device. The double-motor hybrid power drive device solves the problems that a hybrid powersystem in the prior art is complex in structure, high in electric energy consumption, poor in acceleration performance, poor in gear shifting quality and large in control difficulty.

Description

technical field [0001] The invention relates to the field of vehicle hybrid power, and discloses a dual-motor hybrid drive device. Background technique [0002] Currently on the market, most of the improved hybrids based on automatic transmissions add a motor between the engine and the transmission, or connect a motor in parallel to a certain gear of the automatic transmission. The application number is 2010100025104, which discloses a hybrid powertrain and dual-clutch transmission. The principle is to add a motor and a clutch between the original DCT and the engine, which can realize pure electric drive, braking energy recovery, acceleration and torque increase, etc. Function. The disadvantage is that it still needs a dual clutch to shift gears, and cannot rely on the motor for speed regulation, the quality of shifting is poor, and the software control is difficult. [0003] The application number is 2004101024688, which discloses a dual-clutch transmission device for a h...
