Problems solved by technology

[0003] However, in the relevant technologies known to the inventor, the transmissions in hybrid vehicles are generally complex in structure, with few transmission modes and low transmission efficiency.
For example, for most hybrid electric vehicles, the charging process is often realized during driving, the charging mode and charging path are relatively single, and the charging efficiency is poor

Embodiment 1

[0143] Such as figure 1 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.

[0144] The second input shaft 12 is a hollow shaft structure, the first input shaft 11 is a ...

Embodiment 2 Embodiment 5

[0186] Such as Figure 2-Figure 5 As shown, the power transmission system 100 and figure 1 The main difference of the power transmission system 100 shown in is that the rear drive structure is added, and the third motor generator 201, the fourth motor generator 301, and the anti-skid synchronizer 503 are mainly added. For details, please refer to the above-mentioned electronic differential The description of the lock structure will not be repeated here.

Embodiment 6

[0188] Such as Image 6 As shown, the power transmission system 100 in this embodiment and figure 1 The main difference of the power transmission system 100 shown in is that the second motor generator 52 is added, and the second motor generator 52 can be arranged on both sides of the differential 75 to further increase the dynamic performance of the power transmission system 100 .

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 relevant technologies known to the inventor, the transmissions in hybrid vehicles generally have complex structures, few transmission modes, and low transmission efficiency. For example, for most hybrid electric vehicles, the charging process is often implemented during driving, the charging mode and charging path are relatively single, and the charging efficiency is poor.
