Problems solved by technology

[0003] However, in the relevant technologies known to the inventor, the transmissions in hybrid vehicles are 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 speed changer, a power transmission system and a vehicle. The speed changer comprises a plurality of input shafts, a plurality of output shafts, fixed output gears, an output part, a motor gear, a synchronizer of the output part, a reverse output gear and a motor driving shaft, wherein the output part is arranged on one of the output shafts in an empty sleeving manner; the fixed output gears are fixedly arranged on the rest output shafts; the motor gear is fixedly arranged on the output shaft with the output part; the synchronizer of the output part is arranged on one of the output shafts and at least is connected with the output part; the reverse output gear is selectively connected with one of the output shafts in a linkage manner; a motor driving shaft gear which is connected with the motor gear in a linkage manner is fixedly arranged on the motor driving shaft. Through the adoption of the speed changer disclosed by the invention, the transmission modes are increased, and various working conditions, such as charging electricity during parking, and as driving the engine as charging electricity, can be realized.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a transmission, a power transmission system with the transmission, 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 relevant technologies known to the inventor, the transmissions in hybrid vehicles generally have complex structures, 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 ...
