IMPROVING FREIGHT WAGON BRAKING PERFORMANCE TO TAKE ACCOUNT OF THE LIKELIHOOD OF THE WHEELS LOCKING

POVYSENIE TORMOZNOJ EFFEKTIVNOSTI GRUZOVYH VAGONOV S UCETOM VEROJATNOSTI ZAKLINIVANIJA KOLES

On the basis of the results of measurements to establish wheel adhesion during braking, the article assesses the likelihood of the wheels locking in present or improved braking conditions. For lines where the ratio between the actual value and the maximum value of the adhesion coefficient of the running surface of the rails is equal to or greater than 1 to 2, the likelihood of wheel lock is 10-15% greater when braking under load and using synthetic brake shoes. On these lines, before increasing braking capacity, a system for cleaning the surface of the rails should be established.
