FIELD: transport engineering; railless vehicle.
SUBSTANCE: invention can be used in multimember trailer-trains. Proposed trailer-train consists of prime mover and trailer coupled by towing hook and trailer draft pole loop. Prime mover is furnished with steering hydraulic booster including hydraulic pump, hydraulic distributor and steerable wheel control hydraulic cylinder. Cylindrical bushing is fixed on trailer draft pole in longitudinal axis of symmetry with housing of other hydraulic cylinder installed slacklessly for movement in bushing in longitudinal plane being spring-loaded relative to bushing by compression spring. Said hydraulic cylinder is furnished with coupling loop on its end, and piston with rod rigidly connected with trailer draft pole. Overpiston space of housing of said hydraulic cylinder is connected by pipelines to oil lines of control hydraulic booster of prime mover steerable wheels.
EFFECT: improved stability of multimember trailer-train.
