Abstract
The invention relates to a structure of a carbon fiber composite material bicycle wheel frame and a manufacturing method thereof, wherein the friction frame comprises two friction surfaces which are flat surfaces, the friction surfaces form a plurality of annular stack-shaped well-arranged structures, the friction surfaces are contacted with a brake pad in the direction of a ring frame when being contacted, the brake pad directly and vertically confronts a collection surface of cross-section points of a plurality of fiber yarns, and the fiber yarns are shorter as the fiber yarns are worn and are not delaminated without affecting the structure. Meanwhile, when the friction surface and the brake pad are rubbed in parallel along the circumferential direction, the brake pad is rubbed along the linear surface more and more smoothly, so that the brake pad has a certain number of slip resistance, has a comfortable feeling of lubrication without puckery, only consumes the fiber yarns in the circumferential direction when the brake pad is used for a long time, does not have the possibility of delamination, and can really solve the existing defect of delamination caused by heat generation due to friction.
Description
Technical field
The present invention relates to a kind of bicycle wheel frame that uses carbon fiber composite material to make, utilize method for making of the present invention to obtain a kind of have abrasion performance, the impact-resistant mount structure of taking turns.
Background technology
The spare part of high-grade bike selects for use carbon fiber composite material to become common practice at present.The inborn high strength of carbon fibre material, high rigidity and weight-saving material behavior are applied on the bicycle spare part, can satisfy the requirement of bicycle industry really.
Take a broad view of high-grade bike carbon fiber composite materialization in the market, by the popularization process, can be generalized into for four megastages by market product:
One, forward and backward fork (Front Fork, Rear Stays)---because of stressed more not harsh, the initial stage adopts more easily and accepts, and can experience the weight-saving attraction immediately.
Two, crank (Crank), seat pipe (Seat Post), handle (Handle Bar)---because of stressed more harsh, and taking the safety position into account, just introduce market after technology maturation to be produced naturally and the amplification of market acceptance, now has been the mature technology product.
Three, vehicle frame (Frame)---the main body of whole bicycle is visually the most obvious, no matter at the processing procedure of user's application of force, moulding attraction, market and maker, mould, equipment etc., the research and development time-histories is longer, be naturally after just release.At present, the almost marketization comprehensively, but the volume production supply of material.
Four, wheel frame (Rim)---the world market of can saying so thirsts for reaching most last target of bicycle carbon fibre composite materialization at present.Though, during the existing procucts examination is sold on the market, also there are a lot of makers to rack one's brains and want to overcome the difficulty of technology, the mode of making still has disappearance at present, and many problems that need overcome are arranged.
With reference to Figure 11 and Figure 12, be the scheme drawing of existing clamp type (Clincher) with the multiple equipment structure wheel of the traditional carbon fibres of tubular-type (Tubular) frame.Existing carbon fiber wheel frame is a laminar texture, when the wheel frame bears the friction of brake facing, because carbon fiber lamination structure properties of materials makes the wheel frame produce delamination because of abrasion easily, and the situation of structural failure takes place.
With reference to No. 02290151.5 " bicycle rim of composite material " patent of the People's Republic of China (PRC); existing improvement method is to establish aluminum metal wheel frame or the screening glass that one deck has wear-resisting, low heat conduction and rapid heat dissipation characteristic at the brake district outer peripheral face of wheel frame; when making the action of braking; the brake facing of brake directly contacts with screening glass; both can direct contact, and fricative high heat can not be directly conducted to the wheel frame.
But existing method can only be improved and can't deal with problems, and utilizes brake facing and aluminum metal wheel frame or screening glass friction, and consumes brake facing.Further frame is taken turns in protection, and still, must change brake facing again and again for players is not best using method, urgently remains to be improved.
