METHOD OF AND PNEUMATIC BRAKE SYSTEM FOR BRAKING RAILWAY VEHICLES

摘要

FIELD: railway transport. SUBSTANCE: method comes to changing pressure in brake main line according to which metered delivery of compressed air pressure supplied to vehicle brake cylinders is provided. For this purpose in proposed brake system values V_a-additional reservoir capacity, V_c - brake cylinder capacity and V_r - standby reservoir capacity are related by V_a+ αV_c= (&Dgr;P_мV_r- αP_aV_c)/Pmaxempwhere α is experimental coefficient chosen within the limits of 0,5 ≤α≤ 1,5 depending on rigidly of brake cylinder and leverage springs on to which this coefficient acts. &Dgr;P_м is minimum pressure drop in brake main line at braking to provided maximum pressure in brake cylinder at load braking Pmaxempis maximum gauge pressure in brake cylinder at empty braking for empty railway car. P_a is atmospheric pressure. EFFECT: simplified design of brake system, increased smoothness and efficiency of braking of train consisting of empty and loaded cars. 3 cl, 1 dwg
