Abstract
An enhanced shockproof front fork device of a bicycle comprises two front fork tubes provided on both sides, and a shockproof device provided inside the front fork tubes. The two front fork tubes respectively have an opening at the top end, and two socket pipes are respectively inserted into the two front fork tubes through the opening. The two socket pipes are fixedly connected with a fork crown portion at the top, and a bridge portion is connected between the opposite inner sides of the two front fork tubes. The utility model can improve the entire strength of the shockproof front fork by a certain degree by using a doubly-linked front fork tube structure, and can achieve simple appearance and improve assembly convenience.
Description
[technical field]
The utility model is about a kind of automatic shock-proof front fork unit.
[background technology]
The automatic shock-proof front fork mainly uses the bicycle in bicycle for mountain-climbing and the use of general street at present, in order to alleviate the user because bicycle contacts the vibration that is caused with ground, use the structure design of many dampings, therefore many flexible structure assemblies are also arranged, after adding that front fork is installed in vehicle frame, front fork only links the front fork tube on both sides by shoulder, structural strength is greatly affected, so some has the double-ply shoulder at the designed shock-proof front-fork assembly of bicycle for mountain-climbing descending racing car, as announce " shock-proof front-fork assembly structural improvement " No. 462358, see for details shown in Figure 1, it is the front elevation of known descending racing car front fork 10, it is to be worn between two sides that are positioned upper fixing element 11 and following connecting element 12 by two front fork mobile jibs 13, promptly is to have two connecting element stationary positioned, two front fork mobile jibs 13, and the below is established a brake permanent seat 14 again; Its unit price is higher than general anti-vibration bicycle front fork, and and be not suitable for Regular Bicycle and use; See also Fig. 2 to 3 again, front elevation and lateral plan for another known shock-proof front-fork assembly 20, known as seen from the figure shock-proof front-fork assembly 20 is connected with fixedly two front fork sleeve pipes 22 of both sides by last shoulder 21, be provided with a pair of brake arm permanent seat 23 on the front fork sleeve pipe 22 in addition, please note shown in Figure 3 especially, the front fork sleeve pipe 22 of both sides is connected across together with the cross-over connection portion 24 that protrudes from front fork sleeve pipe 22, and cross-over connection portion 24 protrudes in the place ahead of front fork sleeve pipe 22; And the Regular Bicycle shock-proof front-fork assembly has only a shoulder to connect the front fork tube of both sides, wherein some shock-proof front-fork assembly is for the folder formula brake of arranging in pairs or groups, between two front fork tubes, install one group of brake permanent seat again in addition, be fixed on the front fork for folder formula brake, also have design that brake permanent seat and both sides front fork tube are fused.Shown in Fig. 2 and 3, for the installing of brake, permanent seat sees it is outstanding the place ahead of being located at front fork from the side, device in order to folder formula brake, though the structure of its projection is helpful to the structural strength of front fork, but, in the transmission of strength, still have the possibility of impairment because turnover is arranged; So, at structure-reinforced urgently necessity of special improvement that still has of existing shock-proof front-fork assembly.
[utility model content]
The purpose of this utility model is to provide a kind of automatic shock-proof front fork unit of reinforcement, structure with dual connection front fork tube makes the bulk strength of shock-proof front-fork assembly that the raising of certain degree be arranged, and can keep the simple and direct agile of its outward appearance, do not have unnecessary outstanding structure and cause safety worries, it is convenient to improve stack-mounted, and uses lifting image product and value added.
The utility model provides a kind of automatic shock-proof front fork unit of reinforcement, comprises the front fork tube of being located at both sides, is provided with shock absorbing apparatus in this front fork tube inside, it is characterized in that:
The top of two front fork tubes has an opening respectively, and two faucet pipe lower ends are stretched at respectively via this opening among this two front fork tube, and two faucet pipes upper end is fixedly connected on a fork shoulder, and a bridge portion is connected between the two front fork tube relative inner.
The automatic shock-proof front fork unit of described reinforcement is characterized in that: the inboard, top of this bridge portion and two front fork tubes fuses.
The automatic shock-proof front fork unit of described reinforcement is characterized in that: the axis of this fork shoulder, bridge portion and two front fork tubes is that the position is on same straight line.
The automatic shock-proof front fork unit of described reinforcement is characterized in that: be respectively equipped with brake mount on two front fork tubes.
The automatic shock-proof front fork unit of described reinforcement is characterized in that: these fork shoulder both sides are provided with perforation, and each perforation respectively stretches and establish one and screw togather element, and this screws togather element and screws togather with faucet pipe respectively.
Effect of the present utility model and advantage thereof are described below:
1, to compare intensity higher for structure of the present utility model and known front fork, has the dual positioning function of racing car front fork.
2, the utility model front fork tube and bridge portion are one-body molded, compare with known front fork, and assembling does not increase part, has agile outward appearance.
In sum, the automatic shock-proof front fork unit of reinforcement of the present utility model has the function of double fixed location front fork tube, and has simple and direct outward appearance, can take into account safety again.
Be further to describe in detail the utility model, below lift a preferred embodiment now, and conjunction with figs., with formation of the present utility model and the effect explanation as the back of being reached:
