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

Embodiment 1

[0128] Such as figure 1 As shown, the engine 4 is connected with the input end 23d of the double clutch 2d, the first output end 21d of the double clutch 2d is connected with the first input shaft 11, the second output end 22d of the double clutch 2d is connected with the second input shaft 12, and the double clutch 2d is connected with the second input shaft 12. The input end 23d of the clutch 2d and the first output end 21d and the second output end 22d of the double clutch 2d can be in disconnected state at the same time, or the input end 23d of the double clutch 2d can be connected with the first output end 21d and the second output end 21d of the double clutch 2d. One of the two output terminals 22d is engaged, or the input terminal 23d of the dual clutch 2d can be simultaneously engaged with the first output terminal 21d and the second output terminal 22d of the dual clutch 2d.

[0129] The second input shaft 12 is a hollow shaft structure, the first input shaft 11 is a ...

Embodiment 2

[0166] Such as figure 2 As shown, the power transmission system 100 in this embodiment and figure 1 The main difference of the power transmission system 100 shown in is the arrangement of the fifth-speed gear pair and the third-speed gear pair. Gear 3b is vacantly sleeved on the second output shaft 22, and the remaining parts are connected with figure 1 The embodiments are basically the same and will not be repeated here.

Embodiment 3

[0168] Such as image 3 As shown, the power transmission system 100 in this embodiment and figure 1 The main difference of the power transmission system 100 shown in is the position of the fifth-speed driving gear 5a and the first-speed driving gear 1a, in this embodiment, the fifth-speed driving gear 5a is located between the first-speed driving gear 1a and the third-speed driving gear 3a , and the rest with figure 1 The embodiments are basically the same and will not be repeated here.

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, and a motor driving shaft, wherein a driving gear is arranged on each input shaft; a driven gear is arranged on each output shaft, and the driven gears are correspondingly meshed with the driving gears; a first gear of the motor driving shaft and a second gear of the motor driving shaft sleeve the motor driving shaft in an empty sleeving manner, a motor driving shaft synchronizer positioned between the first gear of the motor driving shaft and the second gear of the motor driving shaft is arranged on the motor driving shaft, and the second gear of the motor driving shaft is linked with one of the driven gears. Through the adoption of the speed changer disclosed by the invention, the transmission modes are enriched, 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.
