一、制动缸的发展 100多年来在铁路制动作业中有效地采用制动缸将风动能量转换为机械能。本世纪初,根据当时可达到的冶金和制造技术,制动缸采用笨重铸铁缸体和鞲鞴以及皮碗。本世纪三十年代Knorr公司利用新技术和材料发展的成果,开始生产深拉钢制制动缸。与铸铁制动缸相比,深拉制动缸具有下述优点:
First, the development of brake cylinder Over the past 100 years in the railway brake operation effectively using the brake cylinder will be converted into mechanical energy pneumatic energy. At the beginning of this century, according to the metallurgical and manufacturing technologies that were available at that time, the brake cylinders were made of bulky cast iron cylinder blocks, slugs and cups. In the thirties of this century, Knorr Company began to produce deep drawing steel brake cylinder by utilizing the achievements of new technology and material development. Compared with the cast iron brake cylinder, deep-drawing brake cylinder has the following advantages:
