Abstract

The utility model relates to a shock-absorbing bicycle with the purpose to reduce the integral vibration of the bicycle. The utility model is provided with a front and a back shock-absorbing devices, the fork mouth of two sections of L-shaped shock-absorbing arms on the front shock-absorbing devices is linked with a front shaft, and the other end is linked with a hinge at the front fork end; a shock-absorbing element is arranged between a front fork beam and a shock-absorbing beam, the fork mouth of two sections of L-shaped shock-absorbing arms on the back shock-absorbing device is linked with a back shaft, and the other end is linked with a hinge at the lower part of an oblique beam; a shock-absorbing element is arranged between the upper part of the back oblique beam and the shock-absorbing beam. The utility model is used safely and comfortably, and can be used on the road in bad condition.

Description

Damping bicycle

The utility model relates to a kind of bicycle, particularly relates to a kind of bicycle that shock absorption device is installed.

Bicycle is a kind of widely used walking-replacing tool, is a kind of vehicle easy to use when road conditions are better, but when the road conditions difference, comes from horizontal direction, jolts when the vibrations of vertical direction can make the cyclist ride.Existing bicycle only is that several stage clips are installed under vehicle seat, the vibration of stage clip is uploaded the vertical direction vibrations of leading to the back cant beam certain inhibit function, but only be local damping, be subjected to the no effect of vibrations of vertical direction for headstock, clothes hanger place, vibrations for the bicycle horizontal direction do not have effect substantially, therefore the whole vibrations of bicycle can't alleviate, and exist obviously not enough.

The purpose of this utility model is to be to overcome above-mentioned the deficiencies in the prior art and a kind of bicycle that shock absorption device is installed is provided, and this shock absorption device can effectively absorb the vibrations that come from horizontal direction and vertical direction, and the whole vibrations of bicycle are alleviated.

Technical solution of the present utility model is, comprise front axle (1), front fork (4), front fork crossbeam (6), rear axle (10), back cant beam (9), axis (11), also comprise front damping device and back shock absorption device, described front damping device is that front axle (1) is installed on the prong (7) of two " L " type damping arms (2), these two " L " type damping arm (2) one ends are connected as a single entity with buffer beam (5), hinge-coupled between the other end and front fork (4) end, shock absorber part is installed between front fork crossbeam (6) and the buffer beam (5): described back shock absorption device is that rear axle (10) is installed on the prong (7) of two " L " type damping arms (2), these two L type damping arm (2) one ends are connected as a single entity with buffer beam (5), hinge-coupled between the other end and cant beam (9) bottom, back is installed shock absorber part between back cant beam (9) top and the buffer beam (5).

Above-mentioned shock absorber part can be damping spring (3), also can be the Shock absorber of various structures, as long as can play the purpose of cushioning effect, but for not too high increase cost, should select various commercially available simple Shock absorbers for use.

Described back shock absorption device, two " L " shape damping arm (2) one ends can and the axle sleeve (8) of cant beam (9) bottom, back mount between use hinge-coupled, also can use hinge-coupled with bicycle middle shaft (11).

Described axis (11) also can be installed on " L " type damping arm (2), and distance remains unchanged between the last flower wheel of sprocket wheel and rear axle (10), and the chain degree of tightness can not change because of the motion of back shock absorption device.

The utility model has the advantages that:

At first whole good damping effect, " L " type damping arm is mobilizable among the design, motion along with bicycle, ground-surface unfairness makes cycle wheel be subjected to coming from the application force of horizontal direction and vertical direction, produce vibrations, vibrations are delivered to the arm end by the prong on " L " type damping arm and the point of connection of axletree, the bonded assembly shock absorber part vibrates on the one end buffer beam, the other end moves along with the flexible of shock absorber part, thereby play the purpose of coming damping vibration by elastic force, the vibrations that are subjected on the spider obviously weaken, so the whole vibrations of bicycle alleviate, and effect is obvious.Next is to use safety and comfort: because structural improvement, the whole vibrations of bicycle alleviate, therefore in the bicycle basket, can adorn more thing on the clothes hanger and can be because of not jolting loose dropping out, also can with some ordinary bicycles can not with frangible article such as egg, glass bottle, especially when road conditions were relatively poor, the face of riding that can carry small children needn't be got off and be carried out to alleviate the vibrations that child is subjected to.For the cyclist, the headstock vibrations can make wrist feel tired, the sense of aching is arranged, and the whole irregular vibrations of bicycle can make human body come to harm, unfavorable to health, therefore ride and used the bicycle of this shock absorption device, can effectively alleviate body shake, play a role in health care.

The accompanying drawing drawing is described as follows:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is this embodiment front damping device scheme drawing;

Fig. 3 is a shock absorption device scheme drawing behind this embodiment.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Referring to Fig. 1～Fig. 3:

This damping bicycle, front damping device is by buffer beam 5 two sections " L " type damping arms 2 to be connected as a single entity, there is prong 7 at " L " type damping arm 2 knuckle places, prong 7 is assembled together with front axle 1, use hinge-coupled between " L " type damping arm 2 one ends and front fork 4 terminations, between the middle part of front fork crossbeam 6 and the buffer beam 5 damping spring 3 is installed;

Back shock absorption device is by buffer beam 5 two sections " L " type damping arms 2 to be connected as a single entity, there is prong 7 at " L " type damping arm 2 knuckle places, prong 7 is assembled together with rear axle 10, hinge-coupled between " L " type damping arm 2 one ends and the back cant beam 9 lower end fixed hubs 8 is equipped with damping spring 3 between back cant beam 9 upper ends and buffer beam 5 middle parts.

The design is simple in structure, and original bicycle structure is only done the fraction change, and manufacturer can directly change the line of production, and produces this product in enormous quantities, also can utilize on the bicycle original part to reequip by the condition row that repairs preferably.
