Abstract

The utility model relates to a spring-type driving mechanism for a bicycle. The force generated in moving of the bicycle respectively drives a front wheel boosting cord (12), a saddle boosting rocking arm (6) and a rear wheel boosting rocking arm (8) to drive a front wheel boosting wheel (1), a saddle boosting wheel (5) and a rear wheel boosting wheel (7) to rotate through the shift up and down of a front shock absorber (17), a saddle shock absorber (18) and a rear shock absorber (19). Each boosting wheel respectively drives a big gear (2) to rotate; the big gear (2) drives a spring (3) to rotate; the force is passed to the other end to drive a shaft (13) to rotate through the spring (3); the shaft (13) drives a driving wheel disc (4) to rotate; the driving wheel disc (4) drives a stepless speed variator (10) to rotate through a chain; the stepless speed variator (10) drives a rear wheel flywheel (9) to rotate through the chain; therefore, the bicycle moves forward. When the bicycle is needed to boost in starting or upslope, a wheel disc (11) is rotated to supplement and boost through treading foot stools (20) by feet so as to ensure that the bicycle can normally move under any highway condition.

Description

A kind of spring loaded transmission device that is used for bicycle

The utility model relates to a kind of power of jolting that bicycle is produced and stores in the middle of advancing, and then release is used for the spring loaded transmission device that bicycle is advanced.

At present, well-known walking-replacing tool has motor-car, battery-driven car, bicycle or the like, and the employed energy is oil, electricity or manpower, can not save the energy by actv. like this.

The purpose of this utility model provides a kind of and the supporting spring loaded transmission device of bicycle, it utilizes action of the spring and mechanical drive fully, the drive bicycle is advanced, need not any external energy, very effectively saved the energy and a large amount of physical demandss that has alleviated personnel.

The purpose of this utility model is achieved in that the power of jolting that is produced is from three parts in the middle of car is advanced, that is: front-wheel, trailing wheel, vehicle seat, they are installed the different damping spring of pressure respectively, the displacement up and down that is produced when jolting, front-wheel drive prior mounted power wheel by afterburning backguy, vehicle seat and trailing wheel by afterburning rocking arm and carry out reinforcing; In addition, the rotation when rear wheel is advanced drives power wheel equally by afterburning rocking arm and carries out reinforcing; Afterburning rocking arm is divided into two sections, and one section is solid, and one section is the semi-hollow body, connects then solid with spring and enters the semi-hollow body and fix, and during reinforcing, rocking arm can produce certain push-and-pull strength, makes to cut both ways; Power wheel can only folk prescription to rotation, control storage power apparatus folk prescription to rotation; Afterburning backguy, afterburning rocking arm, power wheel, form, be installed in the right and left of bicycle respectively by two parts; The storage power apparatus is by the spring steel plate that certain elastic force is arranged, and it is centered around on the axle, and an exterior end is fixed on a big gear the inside, and big gear wheel is fixed by box, only allows it roll, and does not allow it rock up and down; The storage power apparatus is formed by two, so that be used alternatingly; When the power from each side rotates big gear wheel by power wheel, big gear wheel drives spring steel plate, spring steel plate begins to rotate, the other end by spring steel plate drives the axle rotation, axle one end initiatively wheel disc rotates simultaneously, initiatively wheel disc drives toric transmission by chain, and then turns a wheel by chain drive flywheel, reaches the purpose of advancing.

Adopt the bicycle of such scheme, on the road surface of jolting relatively, can walk automatically for a long time, according to road conditions, can adopt speed change, brake and personnel guarantee that to the mode of power car travels flexibly, not only need not any energy, can also reduce personnel's physical demands greatly.

Below in conjunction with accompanying drawing and example the utility model is described further.

Fig. 1 is the longitudinal sectional drawing of the utility model storage power apparatus part.

Fig. 2 be Fig. 1 "-" to figure.

Fig. 3 is the longitudinal profile constructional drawing of the power wheel of spring loaded transmission device.

Fig. 4 is the longitudinal sectional drawing of the afterburning rocking arm of spring loaded transmission device.

Among the figure, 2. big gear wheel 3. spring steel plates 4. wheel discs 13. imput shaft 14. solids 15. springs 16. semi-hollow bodies initiatively.

In car was advanced, trailing wheel rotated, and the trailing wheel steamboat is by afterburning rocking arm " Fig. 4 ", and it gathers the power that trailing wheel jolts simultaneously, drove power wheel " Fig. 3 " and rotated; Jolting of producing when car is advanced moves up and down vehicle seat, drives power wheel " Fig. 3 " by spring rocking arm " Fig. 4 " and rotates; Jolting that front-wheel produced when car was advanced then drives power wheel " Fig. 3 " rotation by backguy.

In " Fig. 1 ", big gear wheel (2) at the drive order side of each power wheel " Fig. 3 " to rotation, thereby an end that drives spring steel plate (3) rotates, and power is passed on the axle (13) of the other end by spring steel plate (3), and driving initiatively simultaneously, wheel disc " Fig. 2 " (4) rotates.

In " Fig. 3 ", power wheel can only folk prescription to rotation, impel on the one hand that (2) folk prescription does not make it fall back to rotation on the one hand in the big gear wheel " Fig. 1 ".

In " Fig. 4 ", fixed after solid (14) and spring (15) enter semi-hollow body (16), made solid (14) and semi-hollow body (16) mutual push-and-pull under the effect of spring (15), rotated thereby drive power wheel " Fig. 3 ".
