When electric motor car moves ahead under inertia force effect, that is, stop calutron power output, in centrifugal clutch 1 actively
Part 1a rotating speeds are gradually reduced, and when combining required rotating speed less than centrifugal clutch 1, centrifugation body 1c makees in the elastic force of the first spring 1e
Gradually resetted under, that is, body 1c is centrifuged and is gradually slided to the center position of driving link 1a；In the process, centrifugation body 1c bands are moved
To post 1c1 synchronizing movings, commutation post 1c1 forces driver plate 1d to rotate backward, and then driver plate 1d drives limited post 1k synchronously to move
Dynamic, i.e. limited post 1k is moved near wedge-shaped slot 1a1 bottom surfaces direction, and limited post 1k promotes roller 1f near wedge-shaped slot 1a1 bottoms
Face direction is moved, and second spring 1j is gradually compressed.
Electric motor car is frequently necessary to reversing, and now power is input into from planetary gear 5c, thus freewheel clutch is in released state；
Driving link 1a is reversely rotated along direction shown in arrow in Fig. 4, and the speed of reversing is slower, thus centrifugal clutch is also at separation
