driven axle 1, so, the rotation of passive arbor wheel 8 has certain non-rigid feature, the rotational speed of passive free wheel 10 and the rotational speed of passive arbor wheel 8 different, but under difference is no more than the condition of 25%, wheel 30 is lifted up in clutch can be easily, snap in passive free wheel inner groovy 34 rapidly, thus make the rotational speed of passive free wheel 10 and the rotational speed of passive arbor wheel 8, to be screwed home relative to driven axle 1 by the resultant spring force effect of left spring 5 and right spring 12 and last passive arbor wheel 8 and form geo-stationary and rotate with angular velocity together, realize the closure function in clutch, when on the upside of half drum magnetic shoe 16 is to the lower limb moving to half drum magnetic shoe 16 away from passive arbor wheel 8 direction to passive free wheel 10, the clutch magnetic patch 35 magnetic repulsion effect of half drum magnetic shoe 16 to passive arbor wheel 8 excircle is reduced to and cannot be moved by repulsion clutch magnetic patch 35, now clutch magnetic patch 35 moves to away from passive arbor wheel 8 axis direction under clutch magnetic patch lower spring 32 spring-force driven dual, the clutch clutch of lifting up on device 18 is made to lift up wheel 30 away from toroidal surface in passive free wheel 10, thus make clutch lift up wheel 30 away from passive free wheel inner groovy 34, now passive free wheel 10 is separated with the engagement of passive arbor wheel 8, passive free wheel 10 carries out each spinning with passive arbor wheel 8 under bearing 20 is connected, realize the centrifugation in clutch.
