Embodiment 1

[0142] 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.

[0143] The second input shaft 12 is a hollow shaft structure, the first input shaft 11 is a...

Embodiment 2

[0186] Such as Figure 4 As shown, the power transmission system 100 in this embodiment and figure 2 The main difference of the power transmission system 100 shown in is that the motor power shaft gear 32 transmits with the transmission gear 6 fixedly arranged on the first input shaft 11 through the second intermediate idler gear 62, in other words, the first input shaft 11 is fixed with The transmission gear 6 and the second intermediate idler gear 62 mesh with the transmission gear 6 and the motor power shaft gear 32 respectively. In this embodiment, the power transmission system 100 and figure 2 The power transmission system 100 shown in has a similar transmission mode, and the transmission principle is the same as figure 2 The embodiments are basically the same and will not be repeated here.

Embodiment 3 Embodiment 6

[0188] Such as Figure 5-Figure 8 As shown, the power transmission system 100 and figure 2 The main difference of the power transmission system 100 shown in FIG. The description of the structure will not be repeated here.

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 motor power shaft, a reverse gear, a first reverse intermediate gear, a second reverse intermediate gear and a motor reverse synchronizer, wherein a motor power shaft gear and a motor power shaft synchronizer for being jointed with the motor power shaft gear are arranged on the motor power shaft in an empty sleeving manner; the reserve gear can differentially rotate relative to the motor power shaft, the second reverse intermediate gear is meshed with a gearshift driving gear on one of the input shafts, the first reverse intermediate gear is meshed with the reverse gear, the first reverse intermediate gear is arranged to be selectively linked with the second reverse intermediate gear, and the motor power shaft gear is arranged to be linked with one input shaft or the other input shaft; the motor reserve synchronizer is arranged to be used for synchronizing the reverse gear and the motor power shaft. 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 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...
