The invention discloses a power transmission system for a vehicle and a vehicle with the power transmission system. The power transmission system includes: first and second input shafts, each of which is fixed with a driving gear; first and second output shafts, and one of the first and second output shafts Each upper empty sleeve is provided with a driven gear, and one of the upper empty sleeves in the first and second output shafts is provided with an intermediate idler gear and is also fixedly provided with a transmission gear, and the intermediate idler gear meshes with one of the driving gears ; The first motor generator is connected with the motor power shaft, the motor power shaft is covered with the first gear of the motor power shaft and the second gear of the motor power shaft, the second gear of the motor power shaft meshes with the intermediate idler gear and the first gear of the motor power shaft Engages with the transmission gear; engine, the engine may engage the first and / or second input shaft. The power transmission system of the invention has a simple and compact structure and can realize the parking charging function.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a power transmission system 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 above-mentioned t...
