FIELD: transport engineering; railless vehicles. ^ SUBSTANCE: proposed trailer-train consists of prime mover with fifth-wheel coupler gear mounted on its frame and coupled with semitrailer through pivot movable in longitudinal plane of semitrailer frame, main wheels connected to semitrailer frame by means of spring suspension, and spare wheels. At least pair of spare wheels is installed for rotation on pins rigidly secured on semitrailer frame, being movable arranged for transmission of traction force from prime mover to semitrailer between guides. Said guides are rigidly secured on frame of prime mover in its cross plane and they have wavy profile in horizontal plane. ^ EFFECT: improved efficiency of trailer-train owing to increased load capacity at existing overall dimensions of prime mover and semitrailer. ^ 3 dwg |
