The Improvement Research of the Freight Train Braking System
The train which is made up of 60 cargos (P70 boxcar) was take as the research background, and the synchronous braking system was installed in brake branch pipe, the brake wave and brake time was monitored with the related instruments, and reduction rate of the brake pressure and time-consuming was analyzed. The results indicate that the brake wave transmitted slowly in traditional braking system, in service braking, it was transmitted from the locomotive to the last wagon for 3.621s, and in emergency braking, it took 2.928s, under the condition of the test experiment, the brake wave was transmitted Faster in synchronous braking system, and there is a low braking efficiency in traditional braking system.
