摘　　要：以气刹凸轮式的后轮制动器为研究对象,分析制动器抱死问题的原因。利用图解法模拟制动器凸轮旋转过程中的运动轨迹及摩擦片的磨损量,分析出根本原因。通过优化制动器凸轮形状、调整制动器滚轮中心距等方式解决制动器抱死问题,为制动系统开发工作者提供了一定的参考。Taking the rear wheel brake of air brake cam type as the research object,the causes of brake locking are analyzed.The basic reason was analyzed by simulating the motion track and the wear amount of the friction plate in the process of rotating the brake cam.By optimizing the shape of the brake cam and adjusting the center distance of the brake roller,the problem of brake locking is solved with low cost.This study provides some reference for brake system developers.
