我公司1979～1980年间先后调入民主德国进口的W50LA/K型倾卸汽车五十余部,承担机械施工土方工程运输。经使用发现,有时行驶中突然制动失灵、空驶制动良好但重载不易停车、制动距离长、制动踏板忽高忽矮、制动踏板过硬等。1982年初,我们对这种车的制动系存在的问题开始探讨,对其常见制动故障进行了分析。结果发现:由于蓖麻——乙醇型制动液沸点低(78℃)、易蒸发形成气阻,从而造成制动失效的可能性是存在的,但从实际运行情况看,这种车的制动总泵结构不够台理,也是发生故
My company from 1979 to 1980 has transferred to the Democratic Germany imported W50LA / K-dump truck more than 50, to undertake mechanical construction earthworks transport. The use of the discovery, and sometimes driving sudden failure, good driving but heavy-duty parking is not easy to stop, long braking distance, brake pedal suddenly high and low, brake pedal and so on. In early 1982, we started to discuss the problems of this kind of vehicle braking system, and analyzed the common braking faults. The results showed that: due to the low boiling point of castor-ethanol brake fluid (78 ℃), easily vaporized to form a gas barrier, resulting in the possibility of brake failure there, but from the actual operation, this car system Motion master cylinder structure is not enough Taiwan management, but also happen
