A multi-speed hybrid transmission

Abstract

The present invention proposes a multi-speed hybrid transmission, including an engine, a generator, a drive motor, a planetary gear mechanism, an input shaft, an input shaft of a generator, an output shaft of a drive motor, an output shaft, and a differential. The input shaft is connected with the input shaft, the input shaft is arranged coaxially with the generator input shaft, and is arranged parallel to the output shaft of the driving motor and the output shaft, the end of the input shaft is connected with the planet carrier, and the first, second, and For the third and fourth gears, the fifth, sixth, seventh, eighth, and ninth gears are successively installed on the output shaft, and the tenth gear is installed on the output shaft of the driving motor. 3. The fourth gear meshes with the sixth, seventh, eighth, and ninth gears respectively, the fifth gear meshes with the differential gear, and the tenth gear meshes with the sixth gear. The present invention simplifies transmission system to achieve fast shifting and shorten the power interruption time.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, and in particular relates to a multi-speed hybrid transmission. Background technique [0002] With the increasing awareness of energy conservation and environmental protection in today's society, new energy vehicle technology has begun to develop rapidly. Hybrid vehicle drive technology is the core stage of the development of new energy vehicles. Improving fuel economy and reducing emissions are important issues for hybrid technology. In the existing gearbox, due to the use of the inner and outer sleeve shaft solutions of the input shaft, a shaft, two bearings and other components will be added correspondingly, and the cost is relatively high, and in the process of gear and working mode switching, Without the active speed regulation of the motor, the technical requirements for the synchronizer are high, the time is long, and there is no torque compensation, the vehicle power in...

Problems solved by technology

In the existing gearbox, due to the use of the input shaft inner and outer shaft sleeve schemes, a shaft, two bearings and other parts will be added correspondingly, the cost is high, and in the process of switching gears and working modes, Without the active speed regulation of the motor, the technical requirements for the synchronizer are high, the time is long, and there is no torque compensation, the vehicle power interruption is obvious, and the cost will be correspondingly high, which may cause shift shock

Existing technologies often have the defects of complex structure and excessive loss of efficiency in structure
