Further, described lever part is formed by being fixed on the arc chute on the vehicle body, the force rod that is provided with projection and stretcher; One end of described force rod is arranged on the vehicle body by pin, and projection then is positioned at the inside of arc chute and can slides along the cell wall of this arc chute, and stretcher then links to each other with the other end of force rod.
In order better to realize on described door leaf, also being provided with door leaf groove one and door leaf groove two by the utility model; One end of described steel cable one is fixedly linked with force rod after the fixed pulley break-in, and its other end then twines and be fixed on door leaf groove one inside; One end of described steel cable two twines and is fixed on door leaf groove two inside by the direction opposite with steel cable one winding direction, its other end then directly and this reset components be fixedly linked.
On force rod one end that is connected with stretcher, also be provided with groove, on stretcher, then be provided with the sliding shoe that is complementary with this groove, and this sliding shoe be positioned at this groove inside and can be free to slide along its cell wall.Simultaneously, described reset components is a metal spring.
The utility model compared with prior art has following advantage and beneficial effect:
(1) the utility model structure is comparatively simple, so its cost of manufacture and maintenance cost are comparatively cheap.
(2) the utility model has removed traditional chain, therefore can prevent the fracture situation that chain occurs because of long-term use by actv..
(3) the utility model has not only changed the runner type of drive that standard bicycle adopted, but also a kind of brand new type of drive is provided, and can also save muscle power by actv..
(4) the utility model both can adopt f-w-d, also can adopt back-wheel drive, therefore made that the form of vehicle body is more flexible, can satisfy the demand of different levels.

The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but embodiment of the present utility model is not limited thereto.
Shown in Fig. 1,3,4, keystone configuration of the present utility model is the same with existing bicycle, includes the vehicle body 1 and the front-wheel 3 and the trailing wheel 2 that are arranged on vehicle body 1 rear and front end of bicycle.Simultaneously, also be provided with the door leaf 10 that is used to drive trailing wheel 2 rotations on the bearing of trailing wheel 2, owing to this door leaf 10 is arranged on the trailing wheel 2, so the utility model is a back-wheel drive.
Be used to drive the lever part that rotates door leaf 10 then by being fixed on arc chute 4 on the vehicle body 1, being provided with the force rod 5 of projection 6, and stretcher 7 is formed.Described projection 6 is arranged on the inside of this arc chute 4, and this projection 6 can slide along the arc cell wall of arc chute 4.One end termination of force rod 5 is arranged on the vehicle body 1 by pin, can rotate around pin to guarantee this force rod 5.The other end of force rod 5 is provided with the groove 16 of a rectangle, then is provided with a sliding shoe 17 that is complementary with this groove 16 on the stretcher 7, and this sliding shoe 17 is solidified as a whole with stretcher 17.During installation, this sliding shoe 17 is positioned at groove 16 inside, and can guarantee that stretcher 17 can not break away from force rod 5.Because this sliding shoe 17 can be free to slide along the cell wall of groove 16, therefore by this sliding shoe 17, stretcher 7 just can be free to slide on force rod 5, the user just can be as required, can regulate the distance between stretcher 7 and the arc chute 4 arbitrarily, thereby change the arm of force of formed lever between force rod 5 and the projection 6, realize the labour-saving purpose.
The structure of described door leaf 10 promptly also is provided with door leaf groove 1 and door leaf groove 2 15 as shown in Figure 3 on this door leaf 10, also be fixed with movable pulley 12 simultaneously on the support of vehicle body 1.During connection, an end of steel cable 1 is fixed on the force rod 5, and the other end and twines and be fixed on door leaf groove one 14 inside then on fixed pulley 12 after these fixed pulley 12 break-ins.When this steel cable 1 was wrapped in door leaf groove one 14 inside, it twines number of turns can be a circle, also can be for more than the circle, and the user can choose according to actual conditions.
Can reset after firmly trampling in order to ensure force rod 5, therefore on vehicle body 1, also be fixed with a reset components 8, in order to ensure result of use, the elastomeric metal spring of these reset components 8 preferential employings.During connection, an end of this reset components 8 is fixed on the vehicle body 1, and its other end then is fixedly linked with an end of steel cable 29.The other end of this steel cable 29 is wrapped in the inside of door leaf groove 2 15 and is fixedly linked with it, and steel cable 29 is opposite with the winding direction of steel cable 1 at door leaf groove 2 15 in-to-in winding directions.In like manner, the number of turns that steel cable 29 is twined both can be a circle, also can be for more than the circle.
As shown in Figure 2, present embodiment is compared with embodiment 1, difference is that the door leaf 10 that will be used for the drive wheels rotation is arranged on the bearing of front-wheel 3, accordingly reset components 8 also is fixed on the vehicle frame that is used to support front-wheel 3 simultaneously, and its annexation is all identical with embodiment 1.
In order to ensure normal use, also be provided with one in this embodiment and be used for the sleeve pipe 13 that steel cable 1 passes, promptly the two ends of this sleeve pipe 13 are fixed between fixed pulley 12 and the door leaf 10, and the middle-end of this sleeve pipe 13 part can be fixed on the vehicle body 1 with band.
As mentioned above, just can well realize the utility model.
