Embodiment 1

[0134] 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.

[0135] The second input shaft 12 is a hollow shaft structure, the first input shaft 11 is a...

Embodiment 2

[0177] Such as Figure 4 As shown, the power transmission system 100 in this embodiment and figure 2 The main difference of the drivetrain 100 shown in is the configuration of the intermediate idler 6 . In this embodiment, the intermediate idler gear 6 is configured as a double gear, and has gear parts 61, 62, wherein one gear part 61 meshes with the fourth-speed driving gear 4a, and the other gear part 62 meshes with the second gear 32 of the motor power shaft. engage. For the rest it can be used with figure 2 The power transmission system 100 in the embodiment is basically the same, and will not be repeated here.

Embodiment 3 Embodiment 6

[0179] 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 transmission, a power transmission system and a vehicle. The transmission comprises a plurality of input shafts, a plurality of output shafts, a first reverse gear middle gear, a second reverse gear middle gear and a motor power shaft; the output shafts are in transmission with the input shafts through gear gear pairs; the second reverse gear middle gear is meshed with a gear driving gear on one input shaft, and the first reverse gear middle gear is arranged to be selectively linked with the second reverse gear middle gear; and the motor power shaft is sleeved with a first gear of the motor power shaft and a second gear of the motor power shaft in a non-contact manner, a motor power shaft synchronizer located between the first gear of the motor power shaft and the second gear of the motor power shaft is further arranged on the motor power shaft, the first gear of the motor power shaft is meshed with the first reverse gear middle gear, and the second gear of the motor power shaft is arranged to be linked with one input shaft. By means of the transmission, the transmission mode of the power transmission system with the transmission is enriched at least to a certain degree.

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...
