The principle of work of present embodiment:

1) draw the bar principle of work:

The similar bicycle of Sliding bicycle, after the people sits on the seat cushion 13, hold with two and to draw bar handgrip 9 and control handgrip 8, control handgrip 8 is controlled handgrip 5 by handgrip line 7, so that grasp headstock direction and balance, two arms paddle and can walk simultaneously or alternately then.It is that the long arm of force by drawing bar 10 is passed to the weighing arm of lower end to power, utilizes lever principle, again seesawing by chain 20, drive flywheel 17 and rotate, forwards rotate, promote front-wheel 3 (flower wheel) and rotate thereby flywheel 17 drives trailing wheel 18 again, therefore, Sliding bicycle promptly to overtake.

After car moved ahead, bipod can be put on the sole seat 24 and have a rest, and chain 20 is to reset by tension spring 21.

When stopping, be equipped with the present the same brake 30 of ordinary bicycle, stop.

2) flywheel principle of work:

When chain 20 drive flywheel circles 32 rotate counterclockwise, (as figure) two boss of flywheel circle 32 in-to-ins are pushed down two steel balls 38 respectively and are moved down, two steel balls 38 promote two fore-sets 39 again respectively and also move downward, two fore-sets 39 are oppressed an end of two ratchets 34 again respectively, force two pressure springs 40 in the flywheel heart 35 holes to shrink, make two ratchet 34 1 ends downward, other end perk, the other end promptly enters in two detent recess of ratchet circle 33 inner rings, making flywheel circle 32 drive ratchet circle 33 rotates counterclockwise, ratchet 33 drives the flywheel heart 35 by ratchet 34 and also rotates counterclockwise, thereby the flywheel heart 35 drives Sliding bicycle trailing wheel 18 and rotates counterclockwise, and Sliding bicycle is moved ahead.

After chain 20 stop motions, flywheel circle 32 stops operating immediately, is blocked and two grooves of ratchet circle 33 forward two boss rear portions of flywheel circle 32 in-to-ins to, can not rotate again, and ratchet circle 33 also is forced to stop operating.But still what rotate forward, trailing wheel 18 drives the flywheel heart 35 and also rotates counterclockwise the trailing wheel 18 of whole Sliding bicycle, and two springs 40 are upspring simultaneously, and two ratchet 34 1 ends are risen.And the strength of two fore-sets 39 by spring 40, by ratchet 34 jack-up, steel ball 38 is returned to again in the groove of original ratchet 33, and the other end of ratchet 34 also returns in the detent recess of the flywheel heart 35, thereby trailing wheel 18 continues to rotate counterclockwise to move ahead and has no effect.

When Sliding bicycle stops, in the time of need falling back, back wheels of vehicle 18 is promptly made clockwise direction and is rotated, because ratchet 34 has been returned in the detent recess of the flywheel heart 35, the flywheel heart 35 clockwise rotates also and has no effect, and can not drive ratchet circle 33 and rotate, so, chain 20 can not move during reversing, and that wheel 18 can be done is suitable arbitrarily, rotate counterclockwise, and chain 20 all can not move.

If when chain 20 drive flywheel circles 32 clockwise rotated, flywheel circle 32 only drove ratchet circle 33 and clockwise rotates.Do not have the effect of ratchet 34, can not drive the flywheel heart 35 and rotate, so, no matter how chain 20 reverses (cw) and trailing wheel 18 rotates irrelevant.

Make chain 20 drive trailing wheels 18 and rotate, must make chain 20 to moving ahead, flywheel circle 32 is pressed anticlockwise motion and but can.

Superiority of the present utility model is:

1) wheel is arranged, can walk on the ground.

2) no matter wheel is being gone ahead or fallen back backward, chain can not move.

The utility model is simple in structure, except standard component and general part outsourcing, all the other each zero The manufacturing of part and mutual assembling can adopt common mechanical manufacturing method to realize.
