FIELD: railway transport; two-axle bogies of freight cars. ^ SUBSTANCE: proposed freight-car bogie has spring beam, side frames, bogie center plate with wear-resistant member and elastic or elastic-and-rolling side bearers. Spring beam is installed on spring sets including springs, two of which are installed friction wedges. Side frames rests on bearings 7 of wheelsets 8 by axle-box apertures through V-shaped multiple-layer elastic members 11 and adapters 12. Axle-box apertures are made in form of polygonal pyramid truncated from top whose base is open. Elastic member 15 is placed between adapter and upper flange of axle-box aperture, being essentially body of preset thickness provided with two longitudinal projections in lower part fitted in vertical slots of adapter. ^ EFFECT: reduced dynamic action of car onto track, improved running and operating qualities of bogie. ^ 4 cl, 6 dwg |
