Embodiment 1

[0035] In order to solve the above technical problems, the present invention discloses a hybrid powertrain with front and rear drive continuously variable speed, see figure 1, the front and rear drive continuously variable speed hybrid powertrain includes a hybrid module 1, a pure electric module 2, a first transmission module 3 and a second transmission module 4, and the hybrid module 1 uses the first transmission module 3 to The power is transmitted to the front wheel 6 of the automobile, and the pure electric module 2 transmits power to the rear wheel 7 of the automobile through the second transmission module 4, and the first transmission module 3 and the second transmission module 4 are independently arranged; as a preferred Yes, the second transmission module 4 and the first transmission module 3 can be designed to have the same transmission structure. Further, the power of the hybrid module and the pure electric module are respectively transmitted through the first transm...

Embodiment 2

[0067] In this embodiment, the present invention discloses another structure of a front-rear drive continuously variable speed hybrid powertrain, see figure 2 The difference between this embodiment and the first embodiment is that the first gear 311 and the second gear 312 in the first shifting mechanism 31 are set on the first input shaft 32 in a idling manner, and the first The third gear 313 and the fourth gear 314 are fixed on the first output shaft 33, the first shifting element 315 is fixed on the first input shaft 32, and the first shifting element 315 is located on the Between the first gear 313 and the second gear 312 , the third gear 313 is externally meshed with the first gear 311 , and the fourth gear 314 is externally meshed with the second gear 312 .

[0068] At the same time, the sixth gear 411 and the seventh gear 412 in the second shifting mechanism 41 are set on the second input shaft 42 in a idling manner, and the eighth gear 413 and the ninth gear 414 are ...

Embodiment 3

[0071] In this example, see image 3 The difference from Embodiment 1 is that in this embodiment, the first motor 12 and the engine 11 are respectively arranged on both sides of the first transmission module 3 .

[0072] In addition, other technical features of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of vehicle hybrid power, and discloses a front and back drive continuous-speed-changing hybrid power assembly. The front and back drive continuous-speed-changing hybrid power assembly comprises a hybrid module, a pure electric module, a first transmission module and a second transmission module, the hybrid module transmits the power to the front wheelsof an automobile through the first transmission module, the pure electric module transmits the power to the back wheels of the automobile through the second transmission module, the first transmissionmodule and the second transmission module are arranged independently mutually, and the first transmission module and the second transmission module can realize the transformations of at least two gears respectively. The front and back drive continuous-speed-changing hybrid power assembly solves the problems of the high power consumption and the poor acceleration due to the fact that a motor in ahybrid power assembly without a speed-changing mechanism in the prior art often works in a low-efficiency area and in a over-fixed load for adapting to the torque and speed requirements in the vehicledriving process and the high software control difficulty and the poor gear shifting quality due to the fact that some hybrid power assemblies with speed-changing mechanisms still adopts a step gear shifting mechanism such as a clutch or a synchronizer.

Description

technical field [0001] The invention relates to the technical field of vehicle hybrid power, and discloses a front-rear drive continuous variable speed hybrid power assembly. Background technique [0002] Currently on the market, most of the hybrids based on the improvement of automatic transmissions add a motor between the engine and the transmission, or connect a motor in parallel to a certain gear of the automatic transmission. These solutions improve the ordinary automatic transmission into a hybrid. All have some disadvantages, that is, the engine often cannot work in the low fuel consumption area, the reduction in fuel consumption is small, there are few hybrid drive modes, and more fuel-saving modes cannot be realized, and the clutch is still required to shift gears in steps, and the shifting quality is poor. Control is complicated. [0003] In addition, application number 2004101024688 discloses a dual-clutch transmission device for a hybrid electric vehicle and a m...
