Problems solved by technology

[0004] However, the current dual-clutch hybrid transmission has the following defects: 1. Since the motor is connected to the fourth and sixth gears through the motor drive shaft assembly, the engine and the motor can only drive 2 / 4 / 6 / R at the same time in the hybrid mode. 2. The motor cannot charge the battery when driving. In order to ensure the power supply of the motor, the battery is large in size and high in cost; 3. The structure of the transmission system is complex , takes up a lot of space and is inconvenient to carry

Embodiment 1

[0022] Specifically, as figure 1 As shown, the transmission system of the hybrid vehicle transmission includes an engine 1, an electric motor 2, a coupling clutch 3, an input shaft 4 and an output shaft 5, and there are two input shafts 4, which are respectively the first input shaft 41 and the second input shaft 42, The second input shaft 42 is sheathed on the first input shaft 41 and is rotatably connected with the first input shaft 41 . There are two coupling clutches 3, namely a first clutch 31 and a second clutch 32. The output shaft 5 is connected to the first input shaft 41 and the second input shaft 42 through the gear gear structure corresponding to the gear position of the vehicle. The motor 2 is in drive connection with the first input shaft 41 through the first clutch 31 , and the motor 2 is in drive connection with the second input shaft 42 through the second clutch 32 . The engine 1 is in transmission connection with the electric motor 2 through the interlockin...

Embodiment 2

[0026] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that, as figure 2 As shown, in this embodiment, the gear gear structure includes the first-speed driving gear 7 and the third-speed driving gear 13 that are rotatably connected to the first input shaft 41, and the second-speed driving gear that is fixedly connected or integrally formed on the second input shaft 42. 10 and the fourth gear driving gear 14 and the first gear driven gear 8, the second gear driven gear 11 integrally formed or fixedly connected on the output shaft 5, the third gear driven gear 15 and the fourth gear driven gear 11 that are rotationally connected on the output shaft 5 Driven gear 16, the first gear driving gear 7 meshes with the first gear driven gear 8, the second gear driving gear 10 meshes with the second gear driven gear 11, the third gear driving gear 13 meshes with the third gear driven gear 15, and the fourth gear...

Embodiment 3

[0028] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, there is only one input shaft 4, and the driving gears of all gears are located on the input shaft 4. There is only one shaft clutch 3, and the gear gear structure includes a first-speed driving gear 7 and a second-speed driving gear 10 fixedly connected or integrally formed on the input shaft 4, and a first-speed driven gear connected to the output shaft 5 through bearing rotation. 8 and second gear driven gear 11. The first gear driving gear 7 meshes with the first gear driven gear 8, and the second gear driving gear 10 meshes with the second gear driven gear 11. The output shaft 5 is also fixedly connected with a synchronizer 9 that can make the first gear driven gear 8 or the second gear driven gear 11 be connected with the output shaft 5 by a spline, and the output shaft 5 is also fixedly connected with the parking ra...

Abstract

The invention provides a transmission system of a gearbox of a hybrid electric vehicle, belongs to the technical field of vehicles, and aims to solve the problem that all shifts of the gearbox can operate in a hybrid moving mode, so that the dynamic performance is improved. The transmission system of the gearbox of the hybrid electric vehicle comprises an engine, an electric motor, a coupling clutch, an input shaft and an output shaft, wherein the output shaft is in transmission connection with the input shaft through a shift gear structure corresponding to a vehicle shift; the electric motoris in transmission connection with the input shaft through the coupling clutch; and the engine is in transmission connection with the electric motor through the coupling clutch. The transmission system disclosed by the invention has the following advantages that, all the shifts of the gearbox can run the hybrid moving mode, so that the dynamic performance is good, and oil saving performance is good; in the transmission system, the engine can drive the electric motor to charge an accumulator; and, the transmission system is compact, light in weight and small in size, and complete vehicle carrying is facilitated.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a transmission system of a transmission of a hybrid electric vehicle. Background technique [0002] At present, among new energy vehicles in my country, hybrid vehicles are developing most rapidly. A hybrid vehicle is a vehicle that uses multiple sources of energy, usually a conventional engine (ICE) that uses liquid fuel and an electric motor that uses electrical energy to propel the vehicle. Hybrid vehicles can operate in a variety of drive modes, but have limited battery capacity and rely primarily on engine combustion for power. [0003] Most of the hybrid systems at this stage adopt the P2 hybrid mode, that is, the electric motor is placed on the input shaft of the transmission. Taking the existing seven-speed transmission hybrid system as an example, the hybrid transmission system is mainly based on the current mature dual-clutch transmission technology and motor contro...
