The specific embodiment
The beneficial effect of understanding device context of the present invention in depth and can reach for those skilled in the art are easy to is enumerated a specific embodiment now, and conjunction with figs. is introduced explanation as follows in detail.
A kind of driving device of belt-type bicycle, the solid in the time of please consulting the assembling of driving device of the present invention shown in Figure 2 and bicycle is closed scheme drawing, and perspective exploded view of the present invention shown in Figure 3 is with section combination scheme drawing of the present invention shown in Figure 4.Mainly be: a side of the transmission shaft 11 of bicycle 10 is provided with power wheel 12; The two ends of transmission shaft 11 are provided with two cranks 13; Two cranks 13 are provided with the stretcher 14 that is on, disposes once, and power wheel 12 is provided with oval cam 15, and the outside of oval cam 15 is provided with the tooth portion 151 that is used for drive belt 17 interlocks; Be passed to the trailing wheel 18 of bicycle 10 with rotation strength, bicycle 10 is advanced power wheel 12; It is characterized in that: crank 13 is arranged perpendicular with the major axis of oval cam 15, promptly with the minor axis of oval cam 15 on same axis, the center of oval cam 15 is provided with the combined hole 152 of hollow out; Be used for combining with board 19, combined hole 152 rough being rectangle, four corners of combined hole 152 are provided with hypotenuse 153; The short both sides of combined hole 152 are provided with groove 154, and the center of board 19 is provided with ratchet hole 191, is used for combining with crank 13; The outside of board 19 is corresponding to combined hole 152 inwall places; Coat the elastic body 192 that one deck is processed by the rubber material, the short both sides of elastic body 192 are provided with positioning rib 193, embed in the groove 154 of combined hole 152 with this; Four corners of elastic body 192 are provided with through hole 194; Can supply screw P to wear, with this elastic body 192 is locked on the power wheel 12, both sides that elastic body 192 is long and combined hole 152 inwalls are reserved and are provided with cushion space 195.
