The purpose of this utility model is to realize like this, vehicle frame is an one by the intermediate beam weldering of forward and backward vehicle frame by the bottom, front vehicle frame top welding wheel disc axle sleeve, the slide down axle sleeve is welded as a whole by support column, the top sheave axle sleeve is welded on intermediate beam bottom leading portion again, in the upper and lower pulley axle sleeve upper and lower pulley is housed respectively, control stalk axle sleeve of stage casing, intermediate beam bottom welding.Handlebar and clamp pin are equipped with in the front vehicle frame upper end, lower end dress front fork, and front fork lower end dress front axle, front vehicle wheel and front brake, saddle is installed in back vehicle frame upper end, and rear wheel, rear axle and the rear brake that has flywheel installed in following rear end.The rung of forward and backward wheel replaces with the shape of vane type, and is one with wheel rim, the weldering of wheel wheel.Dress wheel disc axle in the wheel disc axle sleeve on front vehicle frame top, fixedly wheel disc and crank on the wheel disc axle, the crank of wheel disc axle both sides is hinged on corresponding connecting rod one end respectively, one end of the other end of connecting rod and control stalk is hinged on the stretcher axle of corresponding side, two control stalk other ends are hinged on respectively on the control stalk axle two ends, the control stalk axle is contained in the control stalk axle sleeve, and wheel disc is walked around again in the bottom of chain by upper and lower pulley and flywheel installs.Forward and backward shell is fixed on the vehicle frame, and vehicle frame, wheel disc and crank are wrapped up.

The utility model is compared following advantage with standard bicycle: promptly changed the structure that traditional stretcher moves in a circle, except that performance with standard bicycle, also have simple in structure, reasonable in design, novelty handsome in appearance.Performances such as the car body low weight is light, and driving safety is reliable, and is comfortable flexibly.Speed is more than 1.5 times of Regular Bicycle, is suitable for height and rides the people more than 1.3 meters and sail.

Be described further below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model drive system part-structure scheme drawing;

Fig. 3 is the structural representation of the forward and backward wheel of the utility model.

Before, back vehicle frame 4 and 12 bottoms are welded on the intermediate beam two ends respectively, before inciting somebody to action, back vehicle frame is connected as a single entity, front vehicle frame 4 tops welding wheel disc axle sleeve, the slide down axle sleeve is welded on the support column, the top sheave axle sleeve is welded on intermediate beam bottom leading portion, on, top sheave 18 and lower sheave 17 are housed respectively in the lower sheave axle sleeve, stage casing, intermediate beam bottom welding control stalk axle sleeve, handlebar 6 and clamp pin are equipped with in front vehicle frame 4 upper ends, lower end dress front fork 16, front fork lower end dress front axle, front vehicle wheel 1 and front brake 2, saddle 11 is installed in back vehicle frame 12 upper ends, the rear wheel 21 that has flywheel 14 is installed in following rear end, rear axle and rear brake 15, front vehicle wheel 1, the rung that rear wheel 21 is taken turns replaces with the shape of vane type, and and wheel rim, the weldering of wheel wheel is one, dress wheel disc axle 5 in the wheel disc axle sleeve on front vehicle frame 4 tops, fixedly wheel disc 7 and crank 8 on the wheel disc axle, respectively there is a crank 8 wheel disc axle 5 both sides, one end of two cranks is hinged on corresponding connecting rod 10 1 ends respectively, one end of the other end of connecting rod and control stalk 19 is hinged on the axle of relative stretcher 22, the other end of two control stalks 19 is hinged on respectively on the two ends of control stalk axle 20, and the control stalk axle is contained in the control stalk axle sleeve.Chain 9 is by the bottom of pulley 18 up and down and 17, walks around wheel disc 7 and flywheel 14 installs, and forward and backward shell 3 and 13 is fixed on the vehicle frame, with vehicle frame, wheel disc and crank parcel.

Ride when sailing the same with standard bicycle, both feet are stepped on respectively on the stretcher 22 of the left and right sides, both hands are held left and right sides handlebar 6 respectively, and foot-operated stretcher is arcuate movement up and down, affects connecting rod 10, connecting rod affects crank 8, crank drives wheel disc axle 5 and rotates with the wheel disc 7 that is fixed on the wheel disc axle, walks around pulley 17 and 18 up and down by chain 9, drives flywheel 14 and rotates, rear wheel rolls forward, and bicycle is moved ahead.Control stalk 19 had both limited connecting rod 10 and can not swing, and made stretcher 22 do arcuate movement up and down along control stalk axle 20, had solved the dead angle that is produced when crank 8 rotates again.
