Problems solved by technology

[0003] However, in the related technologies known to the inventor, the power transmission system in a hybrid vehicle is generally complex in structure, with few transmission modes and low transmission efficiency.
For example, for most hybrid electric vehicles, the charging process is often realized during driving, the charging mode and charging path are relatively single, and the charging efficiency is poor

Abstract

The invention discloses a power transmission system and a vehicle. The power transmission system comprises an engine, a plurality of input shafts, a plurality of output shafts, a motor power shaft and a first motor-generator, wherein the engine is arranged to be connected with at least one of the plurality of input shafts selectively, and each input shaft is provided with a shift driving gear; each output shaft is provided with a shift driven gear which is meshed with the corresponding shift driving gear; the motor power shaft is arranged to be linked with one of the output shafts; the first motor-generator is arranged to be linked with the motor power shaft, wherein when the motor power shaft is linked with one of the output shafts, the first motor-generator can generate power in running and parking of the vehicle by making use of at least part of power output by the engine. By adopting the power transmission system, transmission modes are enriched, and multiple working conditions of charging in parking, charging for the engine when the engine performs driving and the like can be realized.

Description

technical field [0001] The present invention relates to a power transmission system for a vehicle and a vehicle having 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 relevant technologies known to the inventor, the power transmission system in a hybrid vehicle generally has a complex structure, few transmission modes, and low transmission efficiency. For example, for most hybrid electric vehicles, the charging process is often implemented during driving, the charging mode and charging path are relatively single, and the charging efficiency is poor. Contents of the invention [0004] The present invention aims to solve one of ...
