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 a...

Abstract

The invention discloses a transmission, a power transmission system and a vehicle. The transmission includes: a plurality of input shafts and a plurality of output shafts; first and second reverse intermediate gears, the second reverse intermediate gear meshing with a range drive gear on one of the input shafts, the first reverse intermediate gear It is arranged so that it can move between the meshing position and the disengagement position in the axial direction relative to the second reverse intermediate gear; the motor power shaft, the first motor power shaft gear and the second motor power shaft gear are sheathed on the motor power shaft, and the motor power shaft is located between the two. Between the first synchronizer of the motor power shaft, the first gear of the motor power shaft can be engaged with the first reverse intermediate gear in the meshing position, and the second gear of the motor power shaft is set to be linked with one of the input shafts. The transmission of the present invention is capable of enriching, at least to some extent, the transmission modes of a driveline having the transmission.

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 related art known to the inventor, the transmission structure in the hybrid electric vehicle is generally more complicated, and the transmission paths that can be provided are less, resulting in fewer and single transmission modes of the power transmission system with the transmission, and low transmission efficiency. Contents of the invention [0004] The present invention aims to solve one of the a...
