Fuel economy and dynamic property；4, really full drive in real time may be implemented, by the intelligent control to driving force, can realize and lead
Gravitation controls and the functions such as stability control；5, have speed difference turning function, realization can be coordinated to have more with all-wheel control system
" the double control surfaces " of advantage controls, and realizes vehicle composite turning.In-wheel motor driving system is a new generation of China Vehicle De L'Avant Blinde By Creussot
One hot spot of high performance driven Design scheme is provided.
Either in civil field still in military domain, foreign countries have all surrounded In-wheel motor driving and have carried out the long period
R＆D work.The U.S. just had developed 6 × 6 electric vehicle test platforms, Sweden, Britain, Germany, South Africa, method early in 1986
State, Japan etc. have also successively carried out the research of hub drive system.China In-wheel motor driving technical research starting than it is external compared with
Evening, but my army notices the potential advantages of wheel hub motor very early, and all arranging special topic in continuous several five-year plans gives emphasis branch
It holds.By early-stage study, China's wheel hub (wheel side) motor-drive technique has had been provided with certain Research foundation, but advanced with foreign countries
Level is one of them compared to still having certain gap, technical solution.In the confined space inside wheel rim, integrated motor, speed change/
Deceleration mechanism, brake, at the same time, it must also be considered that heat dissipation and lubrication and the suspension connection between electric driving wheel and car body, wheel
The selection of hub motor driving overall plan directly determines the follow-up implementation of each subsystem component, also contributes to the property of system
Energy, reliability and manufacturing cost.
