Description
Technical field
A kind of manually driven vehicle belong to the bicycle field.
Background technology
Existing bicycle is that the people straddles on narrow and small seat, and both legs are pedaled movable sprocket along with stretcher moves in a circle, and drives trailing wheel and moves ahead through chain, flywheel mechanism.Defective is the vehicle frame heaviness, and people's the both legs amplitude of oscillation is subjected to the circular movement restriction, and it is little to pedal power, and can only straddle, and seat is narrow and small again, rides for a long time to sit and feels very ill.
Summary of the invention
The purpose of this utility model provides a kind of reciprocal drive-type electrodeless variable-speed bicycle, accomplishes that vehicle frame is light and handy, rides to sit comfortablely, and it is unrestricted that people's leg is pedaled amplitude.
The utility model comprises tap and the front vehicle frame that is embedded in the master collet, be equipped with front-wheel on the front vehicle frame, improvements master collet the place ahead is welded with arched arm, the rear is welded with two arc beams, arc beam top is equipped with seat, the arched arm front end is hinged with swing arm, the swing arm upper end is equipped with pedal, be with the speed governing sliding sleeve in the swing arm, the arc beam is equipped with trailing wheel on the rear end, the interior ratchet ring and the trailing wheel cylindrical central sleeve of overriding clutch are fixedly connected, overriding clutch is equipped with on the outside race periphery of ratchet two serving grooves: be wound with the driving stay cord by anticlockwise direction on a serving groove, drive and be fixed on the speed governing sliding sleeve after the guide thimble that is attached on the arc beam is passed in the stay cord outer end, on another serving groove, be wound with the return splicing in the direction of the clock, the return stay cord is connected with pull back spring on the outer end, and the pull back spring other end is fixed on the master collet; Be equipped with the speed governing handle on the tap right-hand member, there are two serving sleeves that connect firmly speed governing handle the inner: be wound with up stay cord by anticlockwise direction on a serving rope sling tube, up stay cord outer end is passed and is fixed on the speed governing sliding sleeve in the swing arm behind the guiding trestle, on another serving sleeve, be wound with descending stay cord in the direction of the clock, descending stay cord outer end is passed and is fixed on behind the guiding trestle under the swing arm on the speed governing sliding sleeve, all is with pilot sleeve on up stay cord, the descending stay cord.
Using method and principle of work are as follows:
The people is sitting on the seat, and hand steered firmly tap with pedaling pedal before the leg, swings swing arm forward, and the speed governing sliding sleeve in the swing arm drives the driving stay cord and moves ahead, and the driving stay cord then drives to surmount from the device anticlockwise direction and rotates, and overriding clutch drives trailing wheel and moves ahead.With it simultaneously, the outside race of overriding clutch is reeled return stay cord conter clockwise and is taken in, and makes the pull back spring elongation.When people's leg was regained, the elastic force of pull back spring back spurred the return stay cord, the outside race clickwise of return stay cord pulling overriding clutch, and outside race dallies on interior ratchet ring this moment.With it simultaneously, outside race will drive stay cord cw coiling and take in, and swing return through speed governing sliding sleeve pulling swing arm backward, so move in circles, and car load is constantly advanced.
If rotate counterclockwise the speed governing handle, a serving sleeve of speed governing handle is reeled and is taken in up stay cord, another serving sleeve is then emitted descending stay cord, affect the speed governing sliding sleeve to rise along swing arm, the travel distance that drives stay cord when making the swing arm swing increases, thereby pulling overriding clutch rotative speed is accelerated, and promptly the trailing wheel gait of march is accelerated.In like manner, if clockwise rotate the speed governing handle, the travel distance that makes swing arm when swing drive stay cord is reduced, the trailing wheel gait of march reduces.
Compared with the prior art, the utility model has following characteristics:
1, volume is little, and is in light weight
The utility model does not have sprocket wheel, chain and supporting mechanism thereof, and designs simplification, so volume is little, in light weight, total length is less than 1000 millimeters, and sitting height is less than 600 millimeters, about 10 kilograms of weight.
2, structure meets the human engineering principle, rides to sit comfortablely, and it is big to pedal power.
The people is sitting on the seat, pedals pedal with leg toward the place ahead, meets the human engineering principle, and both comfortable, it is big to pedal power again." human body is sought secret " book introduction according to the great chief editor that hides: get the seat gesture, right leg is pedaled 262 kilograms of Li Keda, and it is 241 kilograms that left leg is pedaled power.This shows that it is bigger to get seat gesture propulsive effort to pedal.
