The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is made detailed description further.

Fig. 1 is the utility model front structure scheme drawing, because car body is long, have to represent respectively, and Fig. 2 part is the utility model rear structure scheme drawing basically, and same reason have to use Fig. 3, Fig. 4 birds-eye view as its structural representation.

With the general identical part of bicycle front axle 1, front-wheel 2, front-wheel bearing 25, front fork 3 and handlebar are arranged; Rear axle 24, trailing wheel 19, back axle bearing 37, rear axle automation 38, rear wheel cover 18; Drive pedal-rod 14, pedal 39; Different with Regular Bicycle be not establish vehicle seat, body-building people or bicyclist stand, foot pedals repetitive operation about in the of 39, drive pedal-rod 14 and do not do the circumference action, only do low-angle repetitive operation around axle drive shaft 32, by the moving flywheel 9 that drives of the cingulum on the drive sprocket arc 11, flywheel shaft 27 is arranged under it, bearing 26, be connected with transmission A sprocket wheel 10 by driving flywheel 9 again, transmission B sprocket wheel 13, transmission C sprocket wheel 15, being correlated with has transmission B sprocket shaft bearing 33, transmission B sprocket shaft bearing 34, transmission C sprocket shaft bearing 35, transmission C sprocket shaft bearing 36, transmission flywheel 17 on three-step gear shift transmission trailing wheel 19, have messenger chain 22 to link to each other between sprocket wheel, its form is identical with Regular Bicycle with structure; Said flywheel of the utility model and structure are identical with Regular Bicycle, single load bearing, and unidirectional transmission is with ratchet, ratchet; Assembly plate 6, left and right each one, the front portion is located on the connection pipe 4, and connection pipe 4 fuses with front fork 3 usefulness tie bolts, nut 5, and the rear portion of overall plate 6 is fixed on the rear axle 24 of trailing wheel 19; Be connected with driving chain positioning wheel 8 on the driving chain 7, driving chain positioning wheel 8 is left and rightly respectively established one, is fixed on the assembly plate 6; Drive sprocket returning pull-spring 12 is fixed on the assembly plate 6 with set pin 16; The revolution Locating extension spring 21 of drive sprocket arc 11 is connected on the assembly plate 6 with its Locating extension spring bolt of rear end plate 20; Drive pedal-rod 14 and have damping spring 23; As shown in the figure, flywheel shaft 27 is provided with flywheel bearing 26; Drive sprocket bearing support plate 28, support plate all are located on the axle drive shaft 32 with bearing 29, drive sprocket bearing 30.

The utility model course of action is as follows:

Drive sprocket arc 11 and driving pedal-rod 14 are on an axle drive shaft 32, a pin (as left foot) is set foot on pedal 39, driving pedal-rod changes for 14 times, driving chain 7 is pulled, driving driving flywheel 9 rotates counterclockwise, again by transmission A, B, C sprocket wheel 10,13,15 by chain 22 speed changes, transmission flywheel 17, trailing wheel 19 rotates, and drives vehicle body and advances; When this left foot of body builder lifts, drive pedal-rod 14 and sprocket wheel arc 11 under the effect of returning pull-spring 31, get back to original position automatically, driving chain 7 is also got back to original position under the effect of its drive sprocket returning pull-spring 12 simultaneously, waits for driving next time; Meanwhile, body builder's left foot lifts, and steps under the right crus of diaphragm, has the driving pedal-rod 14 of opposite side to depress Body builder's both feet are constantly stepped on, are lifted down successively, and people remain where one is on vehicle body, thereby vehicle body is constantly travelled forward, and reach the purpose of the body-building of riding instead of walk.
