Abstract
A bicycle is composed of handlebar, saddle, main frame, front wheel, back wheel, front fork, back transverse fork and drive mechanism, and features that a back fork seat is arranged between front fork and back wheel axle, the upper and lower sleeves are vertically arranged between back fork seat and back wheel axle, the buffer dampers are arranged between opposite ends of upper and lower sleeves, the upper end of upper sleeve is fixed to back fork seat, and the lower end of lower sleeve is fixed to back wheel axle. The bicycle has the shock absorption function, is simple in structure and convenient to manufacture and process the bicycle body.
Description
The utility model relates to a kind of bicycle.
China's utility application discloses a kind of shockproof bicycle for No. 94236663.8, this bicycle improves the fork that retreads that transmits in the existing bicycle than big bang power, make it to become the form of middle part disjunction, and the buffer-type bumper is set in its disjunction place, make the shaking force that passes to main car frame and bicyclist obtain weakening, make the bicyclist more comfortable, and the corresponding prolongation car body life-span, the generation of contingency reduced.In above-mentioned improvement project, the upper end of the front end of the horizontal fork in back and the fork that retreads with all need change into being connected of main car frame hingedly, this will cause the bigger change of body structure, its processing and fabricating is inconvenient relatively.
The purpose of this utility model provides the more simple antidetonation bicycle of a kind of structure.
Antidetonation bicycle of the present utility model has handlebar, vehicle seat, main car frame, front-wheel, trailing wheel, front fork, the fork that retreads, the horizontal fork in back and driver train.Front fork is arranged between handlebar and the front-wheel wheel shaft, retreads to stick to hold with the horizontal fork front end in back all to captive joint with main car frame.In the utility model, be provided with the back forked standard especially, retread the rear end of the horizontal fork in lower end and back of fork with captiveing joint with back forked standard, vertically be provided with the upper and lower sleeve of mutual socket between back forked standard and the rear axle, be provided with the buffer-type bumper that joins with this opposite end between the opposite end of upper and lower sleeve, captiveing joint with the back forked standard in the upper end of upper bush, captives joint with rear axle in the lower end of lower sleeve.In the utility model, the buffer-type bumper that is arranged between the opposite end of upper and lower sleeve can be by constituting with elastic elements such as contacted spring in two opposite ends or elastic caoutchoucs, also can commercially available existing bumper be set between two opposite ends directly, as air bumper or similar structures.In addition,, also can do similar improvement, to weaken the shaking force that the car front-wheel transmits to the car front fork in order further to improve damping effect.In the utility model, all the other structures of bicycle as handlebar, vehicle seat, main car frame, car front-wheel, trailing wheel and driver train etc., all can be continued to use the version of existing bicycle.Above-mentioned improvement project also can be used on the motor bike, to improve the existing shock-damping structure of motor bike.
Because the utility model bicycle with above-mentioned shock-damping structure does not change the horizontal fork front end in back and stick end and main car frame existing that retread captiveed joint form, makes this bicycle both have shock-absorbing function, structure is comparatively simple again, and the making of being convenient to car body is processed.
Particular content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the overall structure scheme drawing of bicycle among the embodiment.
Fig. 2 is a back vent holder structure scheme drawing.
Shown in Fig. 1～2, the bicycle among the embodiment mainly is made of handlebar 1, vehicle seat 2, trigonometric expression main car frame 3, front-wheel 4, trailing wheel 5, sprocket drive 6 and front fork 7, the fork 8 that retreads, the horizontal fork 9 in back and back forked standard 10.Wherein, front fork 7 is arranged between handlebar and the front-wheel wheel shaft, all captives joint with main car frame 3 with the front end of the horizontal fork 9 in back in the upper end of the fork 8 that retreads, and captives joint with back forked standard 10 in the rear end of the lower end of the fork 8 that retreads and the horizontal fork 9 in back.Vertically be provided with the upper and lower sleeve 11,12 of mutual socket between back forked standard 10 and the rear axle, between the opposite end of upper and lower sleeve, be provided with buffer-type bumper 13.Herein, the concrete form of buffer-type bumper 13 is a goring push spring, and it also can be made of reed, wind spring or the elastic caoutchouc etc. of suitable intensity.The lower end of lower sleeve 12 has axis hole 14, utilizes this axis hole captiveed joint with rear axle in the lower end of lower sleeve 12.In the process of this bicycle of riding, when the bigger back wheels of vehicle of load produces stronger vertical vibrations because of road conditions are bad, because the existence of buffer-type bumper 13, produce axially reciprocating between the upper and lower sleeve, through after forked standard 10 shaking force that passes to main car frame 3 and bicyclist will greatly decay, thereby reduced shockproofness, helped alleviating the harm that vibrations cause.
