踏板车钢制轮圈制动异响问题探析

国内小踏板车常配置钢制辐板轮圈并采用鼓式制动,在骑乘,特别是制动时,常会伴有刺耳的异响声。产生异响的主要原因是轮圈制动毂本身材质与制动蹄块材料匹配不好,制动毂材质的选取直接影响制动时的热导率、消振性能,引起不良噪声。要想解决该问题,主要取决于轮圈的结构形式、材料选用等,但具体问题还要具体分析,针对性地解决。

Abnormal Sound Generated by the Braking of Steel Rim of Moped Wheel

Home-made mopeds are usually fitted with steel rims and drum discs. That easily generates harsh abnormal sound due to the mismatch of materials of brake shoes and brake hubs. The materials for brake hub has direct influence on braking performance, such as the heat conduction rate, and vibration reduction etc. The best solution for this problem is to optimize the structure of wheel and use proper materials.
