城市公交客车制动蹄片耐久性研究
According to the writer s road test experiences and with the brake shoes wearing reliability test data of a 12 m long coach running 90 000 km,this paper researches the equivalent brake rate on several typical roads and the relationships between the brake shoes wearing life test and the normal driving life.
根据多年的道路试验经验,结合某12 m客车9万多km可靠性试验记录,引出"当量制动率"的概念,并对几种路况下的当量制动率进行研究,探索制动蹄片可靠性试验数据与实际寿命之间的关系。
and it mainly is used in manufactue of CA1092 brake.
介绍了一种新淬火技术,主要应用到CA1092刹车蹄片的制造,通过技术改造大大提高了刹车蹄片的耐磨性和硬度,经济效益非常好。
