FIELD: railway transport.
SUBSTANCE: invention relates to design of hopper cars for loose cargoes. Proposed modular hopper car has-drop-shaped body in cross section equipped with hopper with inclined sheets, load-bearing frame 3 with platform flooring and reinforced cantilever parts, center sill members, bolsters rigidly connected by frame side binding. Center sill members are closed on inclined sheets of extreme hoppers rigidly connected with flooring of platforms. Bolsters 4, side binding, inclined sheets and center sill members are interconnected by gussets to take up and distribute impact loads transmitted to hopper car from towing and coupling pintles.
EFFECT: simplified design, reduced weight, improved reliability.
