Embodiment 1

[0163] 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.

[0164] The second input shaft 12 is a hollow shaft structure, the first input shaft 11 is a...

Embodiment 2

[0230] Such as image 3 As shown, the power transmission system 100 in this embodiment and figure 2 The main differences of the drivetrain 100 shown in are at the reverse intermediate gear 72, the idler intermediate gear 73 and the reverse synchronizer 74c. In this embodiment, the reverse intermediate gear 72 and the intermediate idler gear 73 are adjacent to the second output shaft 22, and the reverse synchronizer 74c is disposed on the intermediate idler gear 73 and is used to engage the reverse intermediate gear. 72. 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

[0232] Such as Figure 4 As shown, the power transmission system 100 in this embodiment and image 3 The main difference in the drivetrain 100 shown in is the configuration of the intermediate idler 73 . In this embodiment, the intermediate idler gear 73 is configured as a double gear, and has gear portions 731, 732, one of which gear portion 731 meshes with the second gear driving gear (that is, with the gear driving gear on the one of the input shafts). ), the other gear portion 732 meshes with the first gear 31 of the motor power shaft. For the rest it can be used with image 3 The power transmission system 100 in the embodiment is basically the same, and 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 motor power shaft, a reverse gear, a reverse intermediate gear and an intermediate idle gear, wherein the motor power shaft is sleeved with a first motor power shaft gear and a second motor power shaft gear in a spaced mode; the motor power shaft is sleeved with the reverse gear in a spaced mode, the intermediate idle gear is engaged with a gear driving gear on one input shaft, and the reverse intermediate gear is engaged with the reverse gear and can be combined with the intermediate idle gear; the first motor power shaft gear is engaged with the intermediate idle wheel, and the second motor power shaft gear is engaged with a transmission gear fixed to one output shaft. According to the transmission, transmission modes of the power transmission system provided with the transmission can be enriched at least to a certain extent.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power transmission system for a vehicle 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 above-mentioned technical ...
