摘　　要：对于没有装配制动力调节装置的N2类载货汽车,制动力分配系数直接影响整车的制动稳定性,如何选取该系数将显得极为重要。文章从制动距离、制动强度及避免后轮侧滑要求出发,根据国家相关法规要求,推导出了制动力分配系数的取值范围。计算结果表明,利用该方法所确定的制动力分配系数,能满足汽车在常用路面上行驶制动时的稳定性,同时提高了制动系统的设计效率。The brake stability of N2 class truck is directly affected by the brake force distribution coefficient without equipping with the brake force adjuster. How to select the coefficient will be extremely important. The range of brake force distribution coefficient was derived from the items of braking distance, severity of braking and avoidable rear wheels sideslip according to the national regulatory requirements. The results show that brake force distribution coefficient determined by this method can control the stability of the vehicle during the braking on the normal roads, improving the efficiency of braking system.
