Three-clutch hybrid power transmission

Abstract

The invention discloses a three-clutch hybrid power transmission. The three-clutch hybrid power transmission comprises a driving gear with five gears, a driven gear with five gears, a main reducing gear, a synchronizer, a first clutch, a second clutch, a third clutch, an engine, a motor, a parking mechanism, a differential, a first input shaft, a second input shaft, a first output shaft and a second output shaft; bearings are arranged at the ends, near the motor, of the first output shaft and the second output shaft; driven gears on the first output shaft and the second output shaft are arranged in a staggered manner; driving gears on the input shafts are correspondingly engaged with the driven gears on the output shafts one to one; and the main reducing gear is arranged behind the bearingnearer an output shaft of the motor. The three-clutch hybrid power transmission is higher in transmission efficiency, lower in energy consumption, low in production cost, and gives consideration to both strong hybrid and weak hybrid motor systems to meet A-C grade overall vehicle carrying requirements.

Description

technical field [0001] The invention relates to the technical field of automobile transmissions, in particular to a three-clutch hybrid transmission. Background technique [0002] A HEV is a vehicle that uses multiple energy sources, usually a conventional engine (ICE) using liquid fuel and an electric motor using electrical energy to propel the vehicle. Hybrid vehicles can operate in a variety of drive modes, but have limited battery capacity and rely primarily on engine combustion for power. [0003] Most of the hybrid structures at this stage adopt the P2 hybrid mode, that is, the electric motor is placed on the input shaft of the transmission. The technical scheme is: the C1 clutch and the C2 clutch are respectively connected to the engine, the two input shafts are sleeved on the first input shaft, and the motor is connected to the fourth and sixth gears through the motor transmission shaft assembly. The hybrid power system can implement operating modes such as engine ...

AI Technical Summary

Problems solved by technology

The hybrid transmission system is mainly based on the current mature dual-clutch transmission technology and motor control technology. By changing gears, the drive motor and engine can work in the high-efficiency zone for a long time, which improves work efficiency, increases vehicle dynamics, and improves vehicle performance. Fuel economy, maintaining the driving pleasure of traditional vehicles, but the hybrid system has disadvantages such as high R&D and manufacturing costs, high technical difficulty, large mass, and large volume, which make it inconvenient to carry and the electric motor cannot charge the battery when the engine is driving.
