Abstract

The utility model discloses a carbon fiber composite-material bicycle disc-brake hook reinforcing structure, which is arranged on the outer end of a junction between a rear upper Y-type pipe and a rear lower Y-type pipe of a bicycle pipe; the back part of the rear upper Y-type pipe which is close to the hook is provided with a matching hole for mounting a disc brake; and a connection fin is arranged between an angle of the rear upper Y-type pipe and the rear lower Y-type pipe of the bicycle pipe. The connection fin is arranged below the matching hole of the disc brake to form a triangular structure, so the torsion force which is produced during the working of the disc brake can be effectively decomposed, and the torsion force which is produced by the disc brake can be collectively born by a stable triangle formed by the rear upper Y-type pipe, the rear lower Y-type pipe and the connection fin, and the bearing strength of the hook is greatly improved; moreover, the connection fin is free from having obvious increment of the material weight.

Description

The carbon fiber composite material Bicycle dished brake colludes the pawl additional strengthening

Technical field

The utility model is the bicycle structure about a kind of carbon fiber composite material, is meant that especially a kind of carbon fiber composite material Bicycle dished brake that can promote structural strength colludes the pawl additional strengthening.

Background technology

Carbon fiber composite material is used for the weight that the bicycle manufacturing can alleviate whole bicycle greatly owing to have intensity height, plurality of advantages such as in light weight, now is widely used at bicycle trade.But collude claw portion for bicycle, be cycle frame and the cooperating partly of axletree, owing to need carry out frequent assembly with axletree, and need satisfy high-intensity brake demand, promptly be connected disc brake on the Seat stay in when work, because the torsion that disc brake produces is to be born separately by Seat stay, share the torsion that disc brake produces so need collude the holding capacity that pawl has certain intensity, be that the employing aluminum alloy is made basically so collude pawl; Also have the dealer to adopt carbon fiber composite material to make mountain bike and collude pawl, but for proof strength need increase the material thickness that colludes the pawl place, gain in weight virtually, compare aluminum alloy, weight advantage is also not obvious.

The utility model content

The purpose of this utility model provides a kind of high strength brake requirement of satisfying, and the fiber composite materials Bicycle dished brake that need not obviously to increase material weight simultaneously colludes the pawl additional strengthening.

For achieving the above object, solution of the present utility model is:

A kind of carbon fiber composite material Bicycle dished brake colludes the pawl additional strengthening, and this colludes pawl and is provided in a side of the Seat stay pipe of bicycle tube and the outer end of rear lower fork tube junction; The Seat stay pipe is provided with for the mating holes that disc brake is installed in abutting connection with the back of colluding pawl; Wherein: between the angle of the Seat stay pipe of bicycle tube and rear lower fork tube, be provided with a connection fin.

Described connection fin and Seat stay pipe and rear lower fork tube and to collude pawl one-body molded.

After adopting such scheme, because the utility model is provided with a connection fin between the angle of the Seat stay of bicycle tube and Chain stay, this connection fin is the below that is positioned at the disc brake mating holes, form a triangular structure, the torsion that the energy actv. produces when disc brake is worked decomposes, then the torsion that produces of disc brake can be born by the firm triangle that Seat stay pipe, rear lower fork tube and connection fin form and decompose jointly, makes the whole pawl that colludes bear intensity of force and be greatly improved; And this connection fin there is no the increase of obvious material weight.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of carbon fiber composite material Bicycle dished brake of the present utility model colludes the pawl additional strengthening, be Seat stay pipe 1 at bicycle tube during with rear lower fork tube 3 moulding the outside straight forming in outer end of its junction collude pawl 5; Be provided with in abutting connection with the back of colluding pawl 5 for the mating holes 4 that disc brake is used is installed at Seat stay pipe 1;

Key of the present utility model is: be provided with a connection fin 2 that is connected the two between the angle of Seat stay pipe 1 and rear lower fork tube 3.

Carbon fiber composite material Bicycle dished brake of the present utility model colludes the pawl additional strengthening, for carbon fiber one-body molded, wherein the Seat stay pipe 1, rear lower fork tube 3 is a hollow tubular, disc brake mating holes 4, connection fin 2 and collude pawl 5 for solid, manufacturing process is to fit into shape of product according to design after the cut-parts of carbon yarn dimension preimpregnation cloth, nylon wind pipe is penetrated Seat stay 1 pipe and rear lower fork tube 3 again, integral body is inserted the mould moulding of heating again, and parts as vehicle frame after the moulding use.

Because the utility model is provided with a connection fin 2 between the angle of the Seat stay 1 of bicycle tube and Chain stay 3, this connection fin 2 is the belows that are positioned at disc brake mating holes 4, form a triangular structure, the torsion that the energy actv. produces when disc brake is worked decomposes, then the torsion that produces of disc brake can be born by the firm triangle that Seat stay pipe 1, rear lower fork tube 3 and connection fin 2 form and decompose jointly, makes the whole pawl 5 that colludes bear intensity of force and be greatly improved; And this connection fin 2 there is no the increase of obvious material weight.

Claims

1. a carbon fiber composite material Bicycle dished brake colludes the pawl additional strengthening, and this colludes pawl and is provided in a side of the Seat stay pipe of bicycle tube and the outer end of rear lower fork tube junction; The Seat stay pipe is provided with for the mating holes that disc brake is installed in abutting connection with the back of colluding pawl; It is characterized in that: between the angle of the Seat stay pipe of bicycle tube and rear lower fork tube, be provided with a connection fin.

2. carbon fiber composite material Bicycle dished brake as claimed in claim 1 colludes the pawl additional strengthening, it is characterized in that: connection fin and Seat stay pipe and rear lower fork tube and to collude pawl one-body molded.
