Problems solved by technology

[0003] However, in the related technologies known to the inventor, the power transmission system in a hybrid vehicle is 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

[0160] like figure 2 As shown, the engine 4 is connected to the input end 23d of the dual clutch 2d, the first output end 21d of the dual clutch 2d is connected to the first input shaft 11, the second output end 22d of the dual clutch 2d is connected to 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 may be disconnected at the same time, or the input end 23d of the double clutch 2d may be connected with the first output end 21d and the second output end of the double clutch 2d. One of the two output terminals 22d is engaged, or the input terminal 23d of the dual clutch 2d may be simultaneously engaged with the first output terminal 21d and the second output terminal 22d of the dual clutch 2d.

[0161] The second input shaft 12 is a hollow shaft structure, the first input shaft 11 is a solid shaft, the second input shaft 12 is coaxially sleeved on the first input shaft 11, and a pa...

Embodiment 2

[0227] like image 3 As shown, the powertrain 100 in this embodiment is figure 2 The main differences of the drivetrain 100 shown in are at the reverse intermediate gear 72, the intermediate idler 73 and the reverse synchronizer 74c. In this embodiment, the reverse idler gear 72 and the idler idler 73 are adjacent to the second output shaft 22, and the reverse gear synchronizer 74c is provided on the idler idler 73 and used to engage the reverse idler gear 72. For the rest it is possible to figure 2 The power transmission system 100 in the embodiment is basically the same, and will not be repeated here.

Embodiment 3

[0229] like Figure 4 As shown, the powertrain 100 in this embodiment is image 3 The main difference in the drivetrain 100 shown in is the configuration of the intermediate idler gear 73 . In this embodiment, the intermediate idler gear 73 is configured as a double gear and has gear portions 731 , 732 , wherein one gear portion 731 meshes with the second gear driving gear (ie, with the gear driving gear on the one of the input shafts) ), the other gear part 732 meshes with the first gear 31 of the motor power shaft. For the rest it is possible to 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 power transmission system and a vehicle. The power transmission system comprises an engine, a plurality of input shafts, a plurality of output shafts, a motor power shaft, a reverse gear, a reverse idler gear, a middle idler and a first motor-generator. The engine can be selectively connected with the input shafts. The motor power shaft is sleeved with a motor power shaft first gear and a motor power shaft second gear in an idling mode. The motor power shaft is sleeved with the reverse gear in an idling mode, the middle idler is in linkage with one of the input shafts, the reverse idler gear and the reverse gear are meshed, the reverse idler gear can be connected with the middle idler, the motor power shaft first gear is meshed with the middle idler, and the motor power shaft second gear is meshed with a transmission gear fixed to one input shaft. The first motor-generator is in linkage with the motor power shaft. According to the power transmission system, transmission modes are enriched, and parking charging, driving while charging of the engine and other work conditions can be achieved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a power transmission system for a vehicle and a vehicle having 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 to improve transmission efficiency and fuel economy. [0003] However, in the related art known to the inventor, the power transmission system in a hybrid vehicle generally has a complex structure, few transmission modes, and low transmission efficiency. For example, for the vast majority of hybrid vehicles, the charging process is often implemented during the driving process, and the charging mode and charging path are relatively simple, and the charging efficiency is poor.
