Hybrid electric vehicle transmission

Abstract

The invention relates to a hybrid electric vehicle transmission which comprises a transmission input shaft, a transmission output shaft, a speed-change mechanism and a differential mechanism. After being improved, the transmission is provided with an electric driving mechanism, and the electric driving mechanism comprises a motor, a clutch and a transmission driving part which are sequentially arranged on the transmission input shaft as well as a transmission driven part which is arranged on the transmission output shaft, wherein the motor and the transmission driving part are sleeved on the transmission input shaft in a sliding way, the rotor of the motor is fixedly connected with the driving disc of the clutch, the driven disc of the clutch is fixedly connected with the transmission driving part, and the transmission driving part is in transmission connection with the transmission driven part. In the invention, on the basis of the existing transmission structure, the electric driving mechanism is additionally arranged so that the motor power and the engine power are coupled on the transmission output shaft, thereby realizing a hybrid driving function. The invention has short electric driving routes and has higher efficiency in the processes of driving and energy recovery; and the volume of the improved transmission is not increased obviously, thereby ensuring the convenience of arrangement and assembly of the whole vehicle.

Description

Technical field [0001] The invention relates to a transmission used in automobiles, particularly a transmission used in hybrid vehicles, and belongs to the technical field of automobiles. Background technique [0002] In recent years, with the increasing scarcity of petroleum resources and the continuous improvement of environmental protection requirements, safety, energy saving, and environmental protection have become the themes of today's automobile development. In this context, various hybrid models have been launched. The power sources of hybrid vehicles are internal combustion engine and electric motor. These two power sources generate driving force through the optimal combination under different conditions when the car is running, so that the energy of each power source can make up for the shortcomings of the other power source and make the hybrid The power performance of powered vehicles is fully utilized, fuel consumption is reduced, and exhaust emissions are greatly imp...
