Detailed construction is: vehicle frame is made by the steel pipe of a bending, front end vertically is welded with front axle tube, front axle tube is a short steel pipes, inside be movably installed with the upper column jecket of front fork, front fork is welded with the front wisp of a horizontal direction below upper column jecket on fork, front wisp is a round steel rod, two is porose, the front fork lower end is equipped with front-wheel, the vehicle frame middle part is except there being a horizontal hole to be used for installing axis, also has a hole longitudinally that is used for the mount pad column jecket, in this hole, activity is installed with the seat pillar pipe, the seat pillar pipe is a straight steel pipe, top is fixedly connected with vehicle seat, lower, transverse is welded with rear connecting lever, rear connecting lever is a round steel rod, two is porose, the hole at two is by pin and two back end of tie rod chain connections, two pull bars are that thin steel rod is made, two is porose, the hole of rear end is by pin and rear connecting lever chain connection, the hole of front end is by the hole chain connection at pin and front wisp two, the vehicle frame rear portion is level " Y " shape, vertical ring-type is made at Double-end place " Y " shape, in this ring-type, antifriction-bearing box is installed, rear axle is installed in antifriction-bearing box, rear axle is a round steel rod, centre is fixedly connected with flywheel, right-hand member is fixedly connected with trailing wheel, left end is connected with trailing wheel, at vehicle frame middle part in horizontal hole, axis is installed, axis is a round steel rod, centre is fixedly connected with wheel disc, two ends are fixedly connected with pin and turn, it is exactly that the ordinary bicycle pin turns that pin turns, the end that pin turns is equipped with foot-operated, the outside cover of wheel disc and flywheel has chain, wheel disc, flywheel, chain is all the ordinary bicycle part, axis is different from the ordinary bicycle part: be for preventing that pin from turning motion and getting up and two lateral bracing struts interference, middle axial ratio ordinary bicycle axis of the present utility model is done longerly.

While riding, think that whichaway turns round to turn round with regard to thataway, due to the effect of pull bar, front fork rotates with regard to thataway, and bicycle turns round with regard to thataway, very freely, has liberated both hands fully.

The beneficial effects of the utility model are: fully without walking vehicle (there is no handlebar) at all, no matter how low the speed of a motor vehicle is, because be three-wheel, travel all very stable, liberated both hands fully.

The accompanying drawing explanation:

Below in conjunction with the accompanying drawings.

Fig. 1 is outside drawing of the present utility model.

In figure: 1. front-wheel, 2. front fork, 3. front wisp, 4. front axle tube, 5. pull bar, 6. rear connecting lever, 7. seat pillar pipe, 8. vehicle seat, 9. trailing wheel, 10. rear axle, 11. flywheels, 12. trailing wheels, 13. chains, 14. wheel discs, 15. pin turn, and 16. is foot-operated, 17. axis, 18. vehicle frames.

The specific embodiment:

The utility model comprises front-wheel 1, front fork 2, and front wisp 3, front axle tube 4, pull bar 5, rear connecting lever 6, seat pillar pipe 7, vehicle seat 8, trailing wheel 9, rear axle 10, flywheel 11, trailing wheel 12, chain 13, wheel disc 14, pin turns 15, rides 16, axis 17, vehicle frame 18.Vehicle frame 18 is made by the steel pipe of a bending, front end vertically is welded with front axle tube 4, front axle tube 4 is short steel pipes, inside be movably installed with the upper column jecket of front fork 2, front fork 2 is welded with the front wisp 3 of a horizontal direction below upper column jecket on fork, front wisp 3 is round steel rods, two is porose, front fork 2 lower ends are equipped with front-wheel 1, vehicle frame 18 middle parts are except there being a horizontal hole to be used for installing axis 17, also has a hole longitudinally that is used for mount pad column jecket 7, in this hole, activity is installed with seat pillar pipe 7, seat pillar pipe 7 is straight steel pipes, top is fixedly connected with vehicle seat 8, lower, transverse is welded with rear connecting lever 6, rear connecting lever 6 is round steel rods, two is porose, the hole at two is by pin and two pull bar 5 rear end chain connections, two pull bars 5 are that thin steel rod is made, two is porose, the hole of rear end is by pin and rear connecting lever 6 chain connections, the hole of front end is by the hole chain connection at pin and front wisp 3 two, vehicle frame 18 rear portions are " Y " shape of level, vertical ring-type is made at Double-end place " Y " shape, in this ring-type, antifriction-bearing box is installed, rear axle 10 is installed in antifriction-bearing box, rear axle 10 is round steel rods, centre is fixedly connected with flywheel 11, right-hand member is fixedly connected with trailing wheel 9, left end is connected with trailing wheel 12, at vehicle frame 18 middle parts in horizontal hole, axis 17 is installed, axis 17 is round steel rods, centre is fixedly connected with wheel disc 14, two ends are fixedly connected with pin and turn 15, it is exactly that the ordinary bicycle pin turns that pin turns 15, pin turns 15 end and is equipped with foot-operated 16, the outside cover of wheel disc 14 and flywheel 11 has chain 13, wheel disc 14, flywheel 11, chain 13 is all the ordinary bicycle part, axis 17 is different from the ordinary bicycle part: be for preventing that pin from turning 15 motions and getting up and two lateral bracing struts 5 interference, axis 17 is done longerly than ordinary bicycle axis.
