摘　　要：车辆行驶中后轮为何会＂蹦＂？东风重型载重汽车以其载质量大,通过性好,故障率低,得到广大用户的信赖,在运输市场占有一定保有量,其配置的驱动桥多为贯通式双驱动桥。日前,一辆东风EQ1208G双后桥载货车的用户向笔者反映：该车与同类车型比较，耗油高，高速行驶费力，最突出的怪病是行驶中后轮有“蹦”的现象。此前该车后驱动桥出现故障，曾在修理厂更换过后桥主减器齿轮，行驶一段时间后发现后桥出现发热异响的现象，Recently, a serious accident happened to one of the rear-wheels of Dongfeng EQ1208Q—a model of double rear-axle truck when it was in operating. Having checked the error carefully and studied the operating principles of double rear-axle trucks, the author finally found out the major cause of the accident and correct it.
