Description
Technical field
The present invention relates to a kind of electric automobile drive axle assembly, a kind of a kind of new electric automobile automobile Mike's Fu Xunshi independent suspension structure and motorized motions front-rear axle and steering being combined into drives front and rear axle assembly--suspension type drive axle.
Prospect technology
In recent years, along with improving constantly of people's environmental consciousness, particularly in the recent period for the lifting of PM2.5 index sensitivity, and the appearance of whole nation wide range of haze weather, all allowing the automobile using tradition petrol and diesel oil become the target of public criticism, new-energy automobile becomes focus of attention again.In order to solve the problem of oil shortage, improve air pollution, China using Development of EV as the major action of strategic industry.The new-energy automobile development plan put into effect according to country, by 2012, China's pure electric automobile and plug-in hybrid-power automobile add up volume of production and marketing strove reaching 500,000, by 2020, pure electric automobile
Reaching 2,000,000 with plug-in hybrid-power automobile production capacity, accumulative volume of production and marketing is more than 5,000,000.
In the case of the huge challenge that Present Global auto industry faces financial crisis and energy environment issues, Development of EV, it is achieved the electrification of energy source of car dynamical system, promote the strategic transformation of orthodox car industry, define extensively common recognition.At present, China has put into effect many policies, helps and guide the fast development of electric automobile industry, and government anticipates
It is intended to the competitiveness accelerating to improve domestic electric motor car industry, shortens the period of maturation, it is achieved " bend is overtaken other vehicles " to Automobile Industry Abroad.Therefore, exploitation function admirable, electric automobile that structure is attractive in appearance have become the developing direction of electric automobile.
At present, electric automobile drive axle assembly disclosed on market is as shown in (Fig. 1), and after typically containing major semiaxis 1, semi-minor axis 13, two, left and right brake assembly 2, two, left and right, brake hub 3, rear axle housing assembly 4, two, left and right steel plate torr 5, direct current generator 6, back axle master subtract shell 7, shaft gear 8, two reel gear 9, two shaft gear 10, deep bid tooth 11 and differential assembly 12；One shaft gear 8, two reel gear 9, two shaft gear 10, deep bid tooth 11 are positioned at master and subtract shell 7 inside, deep bid tooth 11 is connected with differential mechanism 12, two shaft gears 10 are connected with deep bid tooth 11, two reel gears 9 are connected with two shaft gears 10, two shaft gears 10 are connected with a shaft gear 8, one shaft gear 8 is connected with direct current generator 6, differential mechanism 12 is connected with major semiaxis 1 and semi-minor axis 13 by axle shaft gear 14, major semiaxis 1, semi-minor axis 13 be connected with left and right Back-braking drum 3 respectively, two, left and right Back-braking drum 3 is connected with two tires of automobile the most respectively.During motion, direct current generator 6 rotates through to lead and subtracts the shaft gear 8 within shell 7, two reel gears 9, two shaft gears 10, deep bid tooth 11 passes to differential mechanism 12, differential mechanism 12 is made to rotate, major semiaxis 1 is driven again by differential mechanism 12, semi-minor axis 13 rotates, major semiaxis 1, after semi-minor axis 13 drives two, brake hub 3 interlocks two tyre rotation of electric automobile, thus complete the feed motion of electric automobile, two brake assemblies 2 control the brake of car load, drive axle is connected with leaf spring and vehicle frame by two steel plate torr 5, this damping rigidity is too strong, cause to driver and passenger and excessively jolt.
It can thus be seen that following two defects of existing electric automobile drive axle assembly existence:
1. being the commonly used non-underslung direct coupled structure of its driving axis, thus drive axle is connected with vehicle frame by leaf spring, damping rigidity is too strong, causes to driver and passenger and excessively jolts；
2. drive axle is single driving, without turning function, so cannot realize forerunner the function turned to, and this structure cannot meet the design requirement that complete vehicle structure is compact；
3. it is overall Welding Structure due to axle housing of the prior art so that electric motor car producer is when adjusting wheelspan, and difficulty is bigger.
