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 a first input shaft, a second input shaft, a first output shaft, a second output shaft and a first motor generator. Transmission between the input shafts and the output shafts is achieved through gear gear pairs. One of the first input shaft and the second input shaft is provided with an empty set output gear in an empty set mode, and the other of the first input shaft and the second input shaft is fixedly provided with a fixed output gear. An empty set reverse gear and a fixed reverse gear are mutually engaged, the empty set reverse gear are arranged on the output shaft provided with the empty set output gear in an empty set mode, and the fixed reverse gear is fixedly arranged to the output shaft provided with the fixed output gear. The motor generator is in linkage with the output shaft provided with the empty set output gear. According to the power transmission system, transmission modes are abundant; meanwhile, gear reversing structures are arranged on the two output shafts respectively, and gear reversing shafts are omitted, and thus the structure of the power transmission system is more compact and reasonable.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power transmission system for a vehicle and a vehicle with it. 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 ...
