2. the locking state during traveling：When the rotating speed of pedal spindle 1 or driver 2 is more than the rotating speed at existing power drive end When, because the effect of the frictional force in accelerator can be exaggerated, therefore the linkage unit 6 of the bigger side of speed can be by separating State is changed into locking state, therefore the bigger side of relative velocity can be in locking state, and the locking time enters for moment for accelerating Row locking.

3. the released state during traveling：Once the larger side linkage unit 6 of rotating speed is changed into locking in the moment of acceleration State, the larger drive end band motor car wheel speed-raising of speed rotate, and the speed of wheel 7 will rise, and in the moment that wheel accelerates, make The relatively low the opposing party's linkage unit 6 of rotating speed unlocks state, bar magnet 60 is returned to medium position by the one end on flat side 610, When be between the driving link and driven member on wheel speed difference maintain one it is stable at the uniform velocity interior when, the position of bar magnet is no longer sent out Changing, no longer clamping lock.
