First, the outline of the principle of the one-way clutch type continuously variable transmission (registered trademark name Zeromax) will be described with reference to FIG. First, the rotation of the input shaft 2 is converted into the reciprocating motion of the connecting rod 6 by the eccentric 4.

力軸１４には、矢印の回転だけが、取出される。One end J thereof swings about a fulcrum K of the speed change link 8, which swings the outer ring 12a of the one-way clutch 12 via the transmission link 10. Thus, on the output shaft 14, only the rotation of the arrow is taken out.

必然的に例えば４分の１に減速されて出力される。When the fulcrum K of the speed change link 8 is moved along the line AB, the transmission link 10 moves the outer ring 1 of the one-way clutch 12.
The swinging angle of 2a can be changed steplessly to zero. Only one transmission unit can take out only intermittent rotation, but if some of them are connected in parallel on the input shaft 2 and the output shaft 14 and their phases are shifted, continuous rotation can be taken out. Further, the input rotation is inevitably decelerated by, for example, 1/4 and output in this mechanism.

い。Since the present invention is configured as described above, the gear shifting operation can be performed quickly and the gear shifting operation can be performed even when the engine is stopped. Further, it is not necessary to step the brake even when the vehicle is stopped on an ascending slope, that is, at the time of 0 rotation.

Since the ratio can be set, there is an effect that it is not necessary to provide a speed reducer one by one.
