Due to the pollution on vehicle wheels or under rainy and snowy weather conditions,a hump yard may have some common problems,such as over speed of car unit rolling at the exit and brake noise caused by car retarder.An in-depth analysis was made on the mechanisms of those problems and a kind of brake beam suitable for existing retarder installation was developed in combination of friction performance test of complex brake splint in lab.According to the performance test results of a prototype,we optimized the structure of over-speed protection and noise reduction of the brake beam and improved the material,composition,and structure of the friction pair of the brake splint.Finally,we developed a new anti-over-speeding and noise-preventive brake beam that satisfies the performance requirements of current retarder installation.
