九、發明說明： 【發明所屬之技術領域】 本發明係有關一種使用碳纖維複合材料之自行車輪 框，利用本發明之製法得到一種具有耐磨耗、耐衝擊之輪 框結構。 【先前技術】 目前高級自行車的零組件選用碳纖維複合材料已蔚為 風氣。破纖維材料先天的高強度、高剛性以及輕量化的材 料特性，應用在自行車零組件上，確實可以滿足自行車產 業的要求。 綜觀目前市場上的高級自行車碳纖維複合材料化，由 市場產品被推廣過程，可歸納成四大階段： 、如、後叉（Front Fork、Rear Stays)—因受力較 不嚴苛’初期採用較易接受，且可立即感受到輕量化的賣 點。 一、 曲柄（Crank)、座管（Seat Post)、握把（HandleIX. Description of the Invention: [Technical Field] The present invention relates to a bicycle wheel frame using a carbon fiber composite material, and a wheel frame structure having wear resistance and impact resistance is obtained by the method of the present invention. [Prior Art] At present, the selection of carbon fiber composite materials for components of advanced bicycles has become popular. The inherent strength, high rigidity and lightweight material properties of broken fiber materials are applied to bicycle components and can indeed meet the requirements of the bicycle industry. Looking at the current advanced carbon fiber composite materials on the market, the market products can be summarized into four major stages: For example, Front Fork (Rear Stays) - due to less stressful initial use Easy to accept, and can immediately feel the lightweight selling point. First, crank (Crank), seat tube (Seat Post), grip (Handle
Bar)—因受力較嚴苛’且較顧及安全性部位，自然待生產 技術成熟與市場接受度放大後才引入市場，現已是成熟技 術產品。 二、 車架（Frame)—整台自行車的主體’在視覺上最明 顯’不論在使用者施力、市場造塑賣點及製造商的製程、 模具、設備等’研發時程較長，自然是較後才推出。目前， 已成乎全面市場化，可量產供貨。 四、輪框（Rin〇-可說是國際市場目前最渴望達成自行 車碳纖維複合材料化的最後一項目標。雖然，市場上已有 產品試賣中，也有很多製造商絞盡腦汁想克服技術的困 難，但目前製造的方式依然存有缺失，有許多尚須克服的 問題點。 參照圖十一與圖十二’為習知夾鉗型（Clincher)與管 狀型（Tubular)的傳統碳纖維複材結構輪框之示意圖。習知 的碳纖維輪框為層狀結構，當輪框承受煞車片的摩擦時， 因為碳纖維積層結構材料的特性容易使輪框因為磨耗而產 生脫層，並發生結構破壞之情事。 蒼J9、?、我國專利公告編號弟540478號「複合材料自行車 輪框結構改良」。習知的改善方法是在輪框的煞車區外周面 設一層具有耐磨、低導熱及散熱快特性之鋁金屬輪框或保 護片，使進行煞車之動作時，煞車器的煞車片直接與保護 片接觸，兩者不會直接接觸，且摩擦產生的高熱不會直接 傳導至輪框。 但，習知的方法只能改善並無法解決問題，利用煞車 片與鋁金屬輪框或保護片摩擦’而消耗煞車片。進—步保 護輪框，但是，對於比賽選手而言必須頻頻更換煞車片並 非最佳使用方法，亟有待加以改良。 有鑑於此，本發明人乃致力於研發一種可以直接與煞 車片接觸，並且不容易因為磨耗而產生脫層的結構設計， 以滿足使用者的需求。 【發明内容】 本發明『碳纖維複合材料自行車輪框之結構及罝制、 所欲解決之問題係在於，習知的碳纖維複合材料於1=^』 避免輪框與煞車片直接接觸而產生磨耗與脫層的4事:了Bar)—Because of the harshness of the force and the safety part, it is natural to wait until the production technology matures and the market acceptance is amplified before it is introduced into the market. It is now a mature technology product. Second, the frame (frame) - the main body of the entire bicycle 'visually the most obvious', regardless of the user's force, the market plastic selling point and the manufacturer's process, molds, equipment, etc. 'long development time, naturally Later launched. At present, it has become fully market-oriented and can be supplied in volume production. Fourth, the wheel frame (Rin〇 - can be said that the international market is currently the most eager to achieve the final goal of bicycle carbon fiber composite material. Although there are already trials on the market, there are many manufacturers who rack their brains to overcome the technology. Difficulties, but there are still some shortcomings in the current manufacturing methods, and there are many problems that need to be overcome. Refer to Figure 11 and Figure 12 for the traditional carbon fiber composite materials of Clincher and Tubular. Schematic diagram of the structural wheel frame. The conventional carbon fiber wheel frame is a layered structure. When the wheel frame is subjected to the friction of the brake piece, the characteristics of the carbon fiber laminated structure material tend to cause delamination of the wheel frame due to wear and structural damage. Cang J9,?, China Patent Announcement No. 540478 "Improvement of composite bicycle wheel frame structure." The conventional improvement method is to provide a layer of wear-resistant, low thermal conductivity and fast heat dissipation on the outer peripheral surface of the brake zone of the wheel frame. The aluminum metal wheel frame or the protection piece enables the brake piece of the brake device to directly contact the protection piece when the brake action is performed, and the two are not in direct contact with each other. The high heat generated is not directly transmitted to the wheel frame. However, the conventional method can only improve and can not solve the problem, and the brake piece is rubbed with the aluminum metal wheel frame or the protective sheet to consume the brake piece. However, it is not the best use for the competitors to change the brake pads frequently, and it needs to be improved. In view of this, the inventors are working on a method of directly contacting the brake shoes, and it is not easy to take off due to wear. The structure of the layer is designed to meet the needs of the user. [Invention] The structure and the structure of the carbon fiber composite bicycle wheel frame and the problem to be solved are based on the conventional carbon fiber composite material in 1=^ Avoiding the direct contact between the wheel frame and the brake shoe to cause wear and delamination:
