Abstract
A front-drive bicycle with good shock absorption performance relates to the improvement of bicycle structure. The utility model provides a front-driving bicycle which is not easy to feel fatigue and has good damping performance. The utility model comprises a frame with a front wheel and a rear wheel, wherein a handlebar and a saddle are arranged above the frame, the frame is structurally characterized in that a beam of the frame is composed of an upper rod and a lower rod which are connected with a bolt in front and connected with the front fork in back, and a front spring and a rear spring on the lower rod are respectively fixed on the lower rod and a connecting rod of a rear fork of the frame; the axle of the front wheel is provided with a big chain wheel and a pedal, the big chain wheel is connected with a chain wheel on the frame bracket through a chain, and the chain wheel on the bracket is connected with a flywheel on the front wheel axle through the chain.
Description
Technical field:
The utility model relates to the improvement of bicycle structure.
Background technology:
Present bicycle is back-wheel drive normally, and therefore the center of gravity of bicycle, causes the tire pressure of trailing wheel big on trailing wheel, and resistance is also big; People are easy to generate fatigue to pedal the time, be difficult to reach ideal velocity.In addition, other shock absorption devices are not set except that tire, saddle, therefore, the car body vibrations are bigger, and the person of riding is felt under the weather, and fatiguability.
The utility model content:
The utility model is exactly at the problems referred to above, provides a kind of people of making to be difficult for the before driving of feeling tired, the bicycle that damping performance is good.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprise have front-wheel, the vehicle frame of trailing wheel, the top of vehicle frame is handlebar, saddle, the crossbeam of its structural feature vehicle frame is by preceding being connected in front fork, after be connected in the upper boom of bolt and lower beam constitutes, the front spring on the lower beam, rear spring are individually fixed on the connecting rod of back vent of lower beam and vehicle frame; The axle of front-wheel is provided with hinge wheel, pedal, and hinge wheel links to each other with the sprocket wheel on the frame brackets by chain, and the sprocket wheel on the support links to each other with the flywheel on the front wheel spindle by chain.
The beneficial effects of the utility model:
1, indefatigability:
Because the center of gravity of bicycle is on trailing wheel, in the time of by bike, front-wheel weight is lighter, and resistance is little, and therefore, the pedal front-wheel is more laborsaving, is difficult for producing fatigue, and the speed of a motor vehicle is also fast;
2, damping performance is good:
Because lower beam is provided with front spring, rear spring, when car body shook, vibrations not only were that saddle, front and back bike tyre absorb, but also can be front spring, rear spring absorption; Car body is operated steadily, make the person of riding feel comfortable, nor fatiguability.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the front-wheel part of Fig. 1.
The specific embodiment:
The utility model comprise have front-wheel 11, the vehicle frame 12 of trailing wheel 1, the top of vehicle frame 12 is handlebar 13, saddle 7, the crossbeam 9 of vehicle frame 12 be by preceding be connected in front fork 14, after be connected in bolt 6 upper boom 8 and lower beam 5 constitute, front spring 10 on the lower beam 5, rear spring 4 are individually fixed on the connecting rod 3 of back vent 2 of lower beam 5 and vehicle frame 12; The axle of front-wheel 11 21 is provided with hinge wheel 19, pedal 22, and hinge wheel 19 links to each other with the sprocket wheel on vehicle frame 12 supports 15 16 by chain 18, and the sprocket wheel 16 on the support 15 links to each other with the flywheel 20 on 11 21 on the front-wheel by chain 17.
The support 15 of sprocket wheel 16 is arranged on the front fork 14 of vehicle frame 12.
During use, during pedal 22 on 11 21 on the person's of riding pedal front-wheel, the hinge wheel 19 on the axle 21 rotates, and the sprocket wheel 16 on the support 15 that drives on the front forks 14 by chain 18 rotates; Sprocket wheel 16 rotates by the flywheel 20 that chain 17 drives on 11 21 on the front-wheels, and flywheel 20 rotates synchronously with front-wheel 11; Front-wheel 11 advances, and car body moves ahead thereupon.
