汽车制动软管是汽车制动系统的重要零件之一,它的性能优劣,关系到国家财产和人民的生命安危。随着我国汽车工业和交通运输事业的发展,对汽车制动软管的需要量越来越大。我国从1954年开始时只有一两个厂生产,年产量不足10万根,目前已发展到近20多个工厂生产,年产量近100万根。因此,对于汽车制动软管的试验,越来越感到它的重要性,在国内对该零件的试验,其设备和试验方法已开始走向统一。汽车制动软管一般有两种,一种是气压制动软管,另一种是液压制动软管。液压制动软
Automobile brake hose is one of the important parts of the vehicle brake system, its performance is good and bad, related to the national property and people’s lives and safety. With the development of China’s automobile industry and transportation, the demand for automobile brake hose is getting bigger and bigger. Since the beginning of 1954, China has only one or two factories producing less than 100,000 pieces of annual output. At present, it has grown to nearly 20 factories and its annual output is nearly 1 million. Therefore, for the test of automobile brake hose, it is more and more important to the test of the parts in the country. The equipment and test methods have begun to unify. There are two types of automotive brake hoses, one is a pneumatic brake hose and the other is a hydraulic brake hose. Hydraulic brake soft
