Abstract


The authors have constructed nomographs of dependence of the gear ratio of a lever-type braking gear on the tare of passenger and freight cars according to the calculated limit coefficient of wheel/rail clutch. It has been shown that for passenger cars with the tare of 53 to 57 ton-force, at a gear ratio 5.3, the 15% skidding reserve in the speed range of 90 to 160 km/h is not maintained. For freight cars with the tare up to 22 ton-force, at a gear ratio 5.72, the basic condition of absence of skidding is not maintained either.
