Versatility is good, simple in structure, and wheel hub motor 1 and gear shift component are integrated in one, small, light-weight, saves space, easily
It is safeguarded in dismounting, reduces use cost, also add a set of air-supply arrangement, make to form continual and steady air stream in guard shield,
By heat caused by wheel hub motor 1 with and discharge, solve the problems, such as that its heat dissipation performance is poor, and two wheel hub motors 1 and two
Change gear (separate transmission component) independent operating is covered, it is non-interference, even if a wheel hub motor 1 or a set of change gear occur
Problem, another wheel hub motor 1 and change gear still can independent operating, enhance the reliability of entire dynamical system, Ke Yishi
For fields such as new-energy automobile and motor technologies.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the invention, it is all the present invention spirit and
Any modification, equivalent substitution or improvement for being made within principle etc., should all be included in the protection scope of the present invention.
