Abstract

The invention belongs to the technical field of electric vehicle transmission, and particularly relates to an electromechanical hybrid transmission stepless speed change structure and a vehicle. The invention provides an electromechanical hybrid transmission stepless speed change structure and a vehicle to solve the problems that in the prior art, stepless speed change cannot be achieved through a driving structure of a hybrid electric vehicle, and the driving experience is reduced due to the jerking feeling in the gear shifting process. The structure comprises a second driving motor and a second power input shaft. An engine power input assembly is connected with the first power input shaft through a clutch, the first power input shaft and the second power input shaft are in driving connection with an output shaft through a transmission mechanism, the transmission mechanism comprises a power collecting assembly and a gear shifting assembly, and the power collecting assembly comprises at least one stepless speed change planet row. The hybrid power driving is achieved through the engine power input assembly and the second driving motor, and meanwhile the stepless speed change is achieved through the power collection assembly comprising the continuously variable transmission planet row.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle transmission, and in particular relates to an electromechanical hybrid transmission continuously variable transmission structure and a vehicle. Background technique [0002] With the promotion of new energy vehicles, my country has become the largest new energy vehicle market in the world. Hybrid vehicles refer to models that use traditional fuels and are equipped with electric motors or engines to improve low-speed power output and fuel consumption. Hybrid electric vehicles are recognized as the most potential new energy vehicles due to their strong power and good fuel economy. By adding additional power sources and drive devices, on the one hand, due to the torque superposition of multiple power sources, the vehicle's performance can be enhanced. At the same time, it can improve the chance of the engine working in the high-efficiency area, thereby improving the fuel economy of the vehic...
