Problems solved by technology

[0006] At present, the power coupling device used for series and parallel connection mostly adopts complex planetary gear mechanism, or some need to install transmission, clutch and other devices, so that the structure of the whole transmission system is not compact.
These mechanisms generally require a large modification or redesign, which requires high production technology and a long trial production cycle; in addition, the control of the planetary gear mechanism is relatively complicated, and it is not easy to realize engineering.

Embodiment Construction

[0040] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0041] Referring to Fig. 1, the described power coupling device of hybrid electric vehicle is to adopt traditional differential gear, realizes the power distribution between power sources (generator 7, electric motor 8, engine 9) in hybrid electric vehicle driving system with work. The left side gear 1 and the right side gear 2 of the differential are respectively connected to the generator 7 and the motor 8 through the left and right side shafts, the driving gear 6 of the final drive is fixedly connected to the output shaft of the engine 9, and the final drive The driving gear 6 of the main reducer and the driven gear 3 of the main reducer are meshed in the state that the two rotation axes are coplanar and perpendicular to each other. The driven gear 3 of the final reducer and the left side shaft gear 1 are on the same rotation axis, The rotation axis of the si...

Abstract

The power coupler for mixed power automobile adopts a traditional differential, and has the left half axle gear and the right half axle gear connected separately to the generator and the motor, main reducing gear with driving gear fixed onto the output shaft of the engine and driven gear meshed with the driving gear to drive the planet gear via one cross, and the motor connected to the driving axle to drive the wheel for running. On the engine and the chassis, there are one engine controller to control the on-off, rotation speed and torque of the power source, one generator controller, one motor controller, and one overall controller to control the foregoing controllers. The present invention has simplified trial manufacture process, simple structure and capacity of automatic stepless speed changing.

Description

technical field [0001] The invention relates to a device for realizing power distribution and control between power sources in a drive system of a hybrid electric vehicle, and more specifically relates to a power coupling device for a hybrid electric vehicle. Background technique [0002] Energy saving and environmental protection are the two major themes of automobile development in the 21st century. Electric vehicles are ideal substitutes for traditional fuel internal combustion engine vehicles. However, due to the limitation of battery energy and the high cost of fuel cells, hybrid vehicles can be regarded as a comprehensive solution to the above feasible solution to the problem. A hybrid vehicle is powered by two or more power sources. The current common solution is to combine an engine with an electric motor and a generator. How to realize the power distribution between the engine, motor and generator of hybrid electric vehicles is one of the key problems that must be ...
