Embodiment 1

[0025] Such as figure 1 As shown, the commercial vehicle hybrid transmission of this embodiment includes an input shaft 1, an intermediate shaft and an output shaft 18, the intermediate shaft includes a first intermediate shaft 5 and a second intermediate shaft 17, and the input shaft 1 is connected to the first intermediate shaft through a shock absorber 2. The intermediate shaft 5 is connected, the first intermediate shaft 5 is connected with the second intermediate shaft 17 through the first clutch 6; the first intermediate shaft 5 is fixedly connected and coaxial with the generator rotor 4, and the second intermediate shaft 17 is connected with the first planetary planet The carrier 10 and the first planetary row sun gear 9 are coaxial, and the second intermediate shaft 17 is fixedly connected with the first planetary row carrier 10, the first planetary row ring gear 11 is fixedly connected with the gearbox housing 19, and the first planetary row The sun gear 9 is fixedly ...

Embodiment 2

[0029] Such as figure 2 As shown, this embodiment provides a commercial vehicle hybrid transmission device. On the basis of Embodiment 1, the commercial vehicle hybrid transmission device of this embodiment also has the following characteristics: the first intermediate shaft 5 is divided into 2 the first sub-shaft 25 connected with the second sub-shaft 26 connected with the first clutch 6; 23 is fixedly connected, and speed-up planetary row sun gear 22 is connected with gearbox housing 19 firmly. After setting the speed-up planetary row, it is beneficial to match the transmission ratio of the rear axle. For a commonly used commercial vehicle engine with a rated speed of 2200r / min, Figure 1 The rear axle transmission ratio of the shown embodiment one commercial vehicle hybrid power transmission is about 3, and figure 2The transmission ratio of the rear axle of the commercial vehicle hybrid power transmission device shown in Embodiment 2 is about 4.4, which greatly facilit...

Embodiment 3

[0031] Such as image 3 As shown, this embodiment provides a hybrid power transmission for commercial vehicles. The difference between the hybrid power transmission for commercial vehicles in this embodiment and the hybrid power transmission for commercial vehicles in Embodiment 1 is that: the first intermediate shaft 5 and the second The intermediate shaft 17 is directly coupled together, and the first clutch 6 is arranged inside the second gear planetary mechanism, the second intermediate shaft 17 is connected with the input end of the first clutch 6, and the second planetary carrier 14 is connected with the output end of the first clutch 6. The output end of the first clutch 6 is connected to the input end of the second clutch 16, and the output end of the second clutch 16 is connected to the second planetary ring gear 13; although part of the space is sacrificed, the motor system and the mechanical system Relatively independent, it is beneficial to reduce production and ma...

The hybrid transmission device of the commercial vehicle can meet the performance requirements of the commercial vehicle.

Description

technical field [0001] The invention relates to the technical field of power transmission devices, in particular to a commercial vehicle hybrid power transmission device. Background technique [0002] Hybrid transmission technology is an important means of energy saving and emission reduction for automobiles, and major automobile manufacturers are actively developing it. Toyota's THS hybrid technology has a good fuel-saving effect. It uses the planetary mechanism to split the power to ensure that the engine always works in the economical range. Requirements for the use of commercial vehicles. [0003] With the increasing pressure of environmental protection, pure electric drive has become the future development direction, and how to conveniently transition from hybrid drive system to electric drive technology route will also be a technical issue that needs to be considered. The motor torque and power required by the existing hybrid transmission device are large, and the co...
