Embodiment 1

[0144] Such as figure 2 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.

[0145] The second input shaft 12 is a hollow shaft structure, the first input shaft 11 is...

Abstract

The invention discloses a gearbox, a power transmission system and a vehicle. The gearbox comprises a plurality of input shafts, a plurality of output shafts, a first reverse intermediate gear, a second reverse intermediate gear and a motor power shaft, wherein the second reverse intermediate gear is meshed with a gearshift driving gear on one of the input shafts, and the first reverse intermediate gear is arranged to move between a meshed position and a disconnected position in the axial direction relative to the second reverse intermediate gear; a motor power shaft first gear, a motor power shaft second gear, and a motor power shaft first synchronizer are arranged on the motor power shaft in an empty sleeving manner, and the motor power shaft first synchronizer is positioned between the motor power shaft first gear and the motor power shaft second gear; the motor power shaft first gear can be in meshed transmission with the first reverse intermediate gear positioned at the meshed position, and the motor power shaft second gear is arranged to be linked with one of the input shafts. According to the gearbox disclosed by the invention, the transmission modes of the power transmission system with the gearbox can be enriched to a certain extent at least.

Description

Technical field [0001] The invention involves the field of vehicle technology, especially the power transmission system with the transmission, the power transmission system with the transmission, and the vehicle with the power transmission system. Background technique [0002] With the continuous consumption of energy, the development and utilization of new energy models have gradually become a trend.As one of the new energy models, hybrid vehicles are driven by engines and / or motors. It has multiple modes and can improve transmission efficiency and fuel economy. [0003] However, among the related technologies learned by the inventor, the transmission structure in hybrid vehicles is generally more complicated, and the transmission path that can be provided is less. As a result, the power transmission system with the transmission is less transmission mode and single, and the transmission efficiency is low. Invention content [0004] The present invention aims to solve one of the...
