Description
本發明是有關一種機械式多連桿碟煞,尤其是指控制煞車的下始點能夠發揮最大的力量,進而達到省力的效果之實用性發明者。 The present invention relates to a mechanical multi-link disc brake, in particular to the practical inventor who can control the lower starting point of the brake to exert the greatest strength, thereby achieving the effect of saving effort.
按,習知自行車利用夾式迫緊機構的煞車塊以左右迫緊輪框的方式來達到制動煞車,習知多片式夾式迫緊機構之自行車煞車系統常因側施力於夾式迫緊機構的左右夾臂之力量無法均勻對稱,使設置於左右夾臂上的煞車塊不能均衡夾掣在自行車輪框,常會造成迫緊機構夾掣時力量不均,而無法使夾式迫緊機構不使用時順利復位,易造成噪音及左右兩煞車塊未均勻磨耗,安全性差之諸多缺點;有鑑於此,遂有一創作人開發一新型專利第M466835號「碟煞卡鉗固定結構」的習用卡鉗固定結構,係將二墊片的頂上端皆設有一凹弧部,又該二墊片的底下端分別向下延伸有二插腳,當二螺栓分別貫穿該二墊片並將該卡鉗螺鎖於自行車前叉時,該二插腳得套入嵌合於該卡鉗的所對應的橢圓長孔內,並將各螺栓的外弧部得抵緊於各墊片的凹弧部,藉由該二插腳使該華司墊塊不會與該碟煞卡鉗的橢圓長孔作相對旋轉;然而該習知結構在作動煞車施力時無法達到較佳省力的效果。 According to the conventional bicycle, the brake block of the clamp-type clamping mechanism is used to squeeze the wheel frame from left to right to achieve braking. The bicycle brake system of the conventional multi-piece clamp-type clamping mechanism often exerts lateral force on the clamp-type clamping. The force of the left and right clamping arms of the mechanism cannot be evenly symmetrical, so that the brake blocks set on the left and right clamping arms cannot be clamped on the bicycle wheel frame in a balanced manner. This often results in uneven force when the clamping mechanism is clamped, and the clamping mechanism cannot be used. Smooth resetting when not in use is likely to cause noise and uneven wear of the left and right brake blocks, and many disadvantages such as poor safety. In view of this, a creator developed a new patent No. M466835 "Disc brake caliper fixing structure" for conventional caliper fixing The structure is that the top and upper ends of the two shims are provided with a concave arc, and the bottom and bottom ends of the two shims are respectively extended downward with two pins, when the two bolts penetrate the two shims respectively and lock the caliper on the bicycle When the front fork is used, the two prongs should be fitted into the corresponding oval long hole of the caliper, and the outer arc of each bolt should be pressed against the concave arc of each spacer, and the two prongs are used to make The washer block does not rotate relative to the oval long hole of the disc brake caliper; however, the conventional structure cannot achieve a better labor saving effect when the brake is applied.
是以,針對上述習知結構所存在之問題點,如何開發一種更具理想實用性之創新結構,實使用消費者所殷切企盼,亦是相關業者須努力研 發突破之目標及方向。有鑑於此,本案發明人本於多年設計經驗,詳加設計本發明構件並經過實際審慎評估後,終得一確具實用性之本發明。 Therefore, in view of the problems of the above-mentioned conventional structure, how to develop an innovative structure with more ideal and practicality, and actually use what consumers are eagerly awaiting, is also the relevant industry must work hard to study The goal and direction of the breakthrough.
