Abstract

The utility model relates to a damping device for bicycles, which can reduce the fatigue of people when people ride bicycles. A square convex tube (9) is inserted in the inner cavity of a circular cover tube (5), and one end of the square convex tube (9) and one end of the circular cover tube (5) are respectively pressed on a spring (4) and a rubber stripe tube (8) in a movable mode to achieve the purpose of shock absorption. The outer circle of one end of the square convex tube (9) is connected with a pad helicoid (6), a pad hollow ring (7) is connected in the inner circle of one end of a circular pad tube (5), and the whole device is connected between the vertical tube of a bicycle handle and a front fork (10).

Description

Damping device for bicycle

The present invention is the shock absorption device of bicycle.

The bicycle that our country produces does not have shock absorption device, therefore, no matter be any bicycle, all can make the people produce tired sensation, and is more tired by bike under especially long-distance or the environment that Uneven road is smooth.

The present invention has designed a kind of bicycle shock absorption device, fatigue that it can help the cyclist to avoid producing vibrations by bike to be brought and the consumption that alleviates muscle power.

The structure of bicycle shock absorption device of the present invention includes the inner chamber that garden shape vestlet and square protruding pipe, protruding pipe box are inserted in vestlet, the upper end roof pressure the spring in the vestlet, the lower end of vestlet is with the rubber line pipe contact that is nested with on protruding pipe, be screwed in the inner chamber of shape vestlet lower end, garden that to connect an endoporus be the empty circle of square pad, bung flange is filled up by being threaded one in the garden outside the upper end of square protruding pipe.With empty circle of pad and pad bung flange vestlet and protruding pipe are flexibly connected, become a complete device of this invention.This device passes the front truck pipe of bicycle tripod.One of its vestlet is threaded with stem, and its protruding pipe during bicycle running, just can obtain non-good damping effect with bicycle front fork captive joint jail.

Fig. 1 is the position view that the bicycle shock absorption device is assemblied in bicycle.

Fig. 2 is a bicycle shock absorption device constructional drawing.

In the drawings, this shock absorption device 2 is nested with in front truck pipe 3 inner chambers, and its position is fixed by existing front fork locknut and wheel ball bearing on the bicycle, and 5 one of its garden shape vestlets are threaded with stem 1, and its square protruding pipe 9 and front fork 10 are connected as a single entity.

In Fig. 2, square protruding pipe 9 covers of captive joint front fork 8 are inserted in garden shape vestlet 5 inner chambers, one crown is pressed in the spring 4 in shape vestlet 5 inner chambers of garden, fill up bung flange 6 with being threaded one on the garden outside, the lower end suit a rubber line pipe 8, and the lower end roof pressure of vestlet 5 is on rubber line pipe 8, and fixing an inner chamber with thin nail in the garden in it is the square empty circle 7 of pad, the square cavities and the square protruding pipe of the empty circle 7 of pad match, and the vibrations of front-wheel reach double-layer shock-absorbing by spring 4 and rubber line pipe 8.In practice is made, get the height of spring 4 and the height of India rubber tube 8 and equate, can improve damping effect and service life.Garden shape vestlet 5 and square protruding pipe 9 are realized flexibly connecting by empty circle 7 of pad and pad bung flange 6, when stem 1 is subjected to the power that lifts and front fork 10 and square protruding pipe gravitate together with garden shape vestlet 5, their disengagings that can not relatively move, realized the heavy keying fit connection, on the contrary, garden shape vestlet 5 by gravitys, square protruding pipe 9 is under the vertical upward force effect of front-wheel, they just by this difference roof pressure rubber line pipe 8 and spring 4, reach desirable damping and shockproof effect.This device also can be used on the mini-motorcycle.

Compare with present bicycle from the actual effect of using design-calculated shock absorption device of the present invention, maximum benefit is comfortable to the cyclist, has avoided long-distance fatigue by bike, significantly can improve the consumption of muscle power to the rider of hill path and band weight.

Claims

1, the bicycle shock absorption device is to be sleeved in the front truck pipe (3), be connected in stem (1) and front fork (10), the inner chamber that it is characterized in that square protruding pipe (9) cover insertion garden shape vestlet (5), roof pressure the spring (4) in the chamber, garden shape vestlet (5) lower end is with rubber line pipe (8) contact that is enclosed within on the square protruding pipe (9), square protruding this (9) one end is connected with pad bung flange (6) on the outer garden, and it is the square empty circle of pad (7) that the interior garden of garden shape vestlet (5) one ends is connected with inner chamber.

2,, it is characterized in that the height of spring (4) and rubber line pipe (8) equates by the described bicycle shock absorption device of claim 1.
