国标CB 7258—1997《机动车运行安全技术条件》的附录C中有天台试制动性能检验方法中规定:“用滚筒式制动试验台检验,存测量制动时,为了获得足够的附着力,以避免车轮抱死,允许在车辆上增加足够的附加质量或施加相当于附加质量的作用力(附加质量或作用力不计入轴荷)。”笔者认为这种提法值得商榷。 National standard CB 7258-1997 “Technical conditions of motor vehicle safety” appendix C rover test braking performance test method provides that: “With the drum brake test stand test, save the measurement brake, in order to obtain sufficient adhesion To avoid locking the wheel, allowing enough additional mass to be added to the vehicle or applying a force equivalent to the added mass (additional mass or force is not included in the axle load). ”I think this formulation is questionable.
