Abstract

The invention discloses a power transmission system for a vehicle and the vehicle provided with the power transmission system. The power transmission system comprises a first input shaft, a second input shaft, a first output shaft, a second output shaft, a first motor generator and an engine; the first motor generator is connected with a motor power shaft, the motor power shaft is sleeved with a first gear of the motor power shaft and a second gear of the motor power shaft in a non-contact manner, the second gear of the motor power shaft is meshed with a driven gear on the output shafts, and a synchronizer is arranged between the first gear of the motor power shaft and the second gear of the motor power shaft; and the engine is selectively connected to one of the first input shaft and / or the second input shaft. The power transmission system is compact in structure, small in axial and radial size and good in dynamic property, and the parking charging function and the full-gear hybrid working condition can be achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a power transmission system for a vehicle and a vehicle with the power transmission system. Background technique [0002] With the continuous consumption of energy, the development and utilization of new energy vehicles has gradually become a trend. As one of the new energy vehicles, a hybrid vehicle is driven by an engine and / or an electric motor, and has multiple modes, which can improve transmission efficiency and fuel economy. [0003] However, in the related technologies known to the inventor, the power transmission system in a hybrid vehicle is generally complex in structure, bulky, and often cannot realize the parking charging function, and the hybrid mode is single, and only the hybrid of individual gears can be realized. mode, it is impossible to achieve a full gear hybrid mode. Contents of the invention [0004] The present invention aims to solve one of the abo...
