Hybrid power car electric speedup clutch and control method thereof

Abstract

The invention discloses a hybrid power car electric speedup clutch and a control method thereof. The hybrid power car electric speedup clutch comprises a gear motor, a feed screw nut mechanism, a shell, brake calipers and a planetary gear train assembly. The shell is of a square-end-up and round-end-down disk-type shell structure, and the planetary gear train assembly is installed in a round area.A sun wheel is fixed to a shaft of a planet carrier through a bearing, a planet gear is fixed to the planet carrier, the planet carrier is embedded into an outer gear ring, and the planet gear separately meshes with the sun wheel and the outer gear ring. An inner rotating hub and a damping machine shell are sequentially arranged outside the outer gear ring, and the damping machine shell is fixedto the outer gear ring through bolts. Four rectangular slots are separately formed in the damping machine shell, the inner rotating hub and the outer gear ring, and each of the rectangular slots is internally provided with a torsion spring. The planet carrier is connected with an engine through the shaft penetrating through the sun wheel. The gear motor is connected with the feed screw nut mechanism, the feed screw nut mechanism is connected with the brake calipers through steel wires, the brake calipers are arranged in the shell in a floating mode, and the brake calipers are provided with twofriction plates. The hybrid power car electric speedup clutch and the control method have the advantages of simple structure, short axial size, reduction of torsional vibration and the like.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to an electric speed-increasing clutch of a hybrid electric vehicle and a control method thereof. Background technique [0002] The development of new energy vehicles is an inevitable choice to achieve energy conservation and emission reduction and the sustainable development of the automobile industry. In recent years, technologies related to pure electric vehicles and fuel cell electric vehicles have achieved rapid development. However, due to the problems of low energy density, short service life and high price of batteries and fuel cells, the industrialization process of the two has been severely restricted. . As a transitional vehicle from a fuel vehicle to a pure electric vehicle, a hybrid electric vehicle can couple the power of the engine and the drive motor, which can not only take advantage of the engine's long working time and good power, but also give f...

AI Technical Summary

Problems solved by technology

The large axial length will inevitably affect the layout of the whole vehicle. For rear-drive models, it can be solved by adjusting the space layout, but it will affect the overall appearance and ride comfort; for front-drive models, the drive system should be arranged on both sides of the drive In the middle of the wheel, there is a big problem

Many models solve the problem of insufficient axial space by sacrificing the power of the motor and engine or choosing a wider body, which leads to the contradiction of insufficient power for small models and poor economy for large models
