Described two-shift automatic speed variator can, when bottom gear magnetic clutch 3 and top gear clutch 2 is all separated, be realized the neutral of electric vehicle; Can coordinate motor reversal, realize electric vehicle and reverse gear.
Above-mentioned two-shift automatic speed variator is simple in structure, and inheritance is good, can, by rationally controlling the Engage and disengage time of bottom gear magnetic clutch 3 and top gear magnetic clutch 2, realize automatic power failure-free speed change.
Described differential mechanism 8 and the semiaxis 9 power differential for bottom gear driven gear 7 and top gear are transmitted from gear 5, and exported by semiaxis 9.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
