TRAILER FOR TRAILER-TRAIN Russian patent published in 2006 - IPC B62D13/02 B62D7/16 

FIELD: transport engineering.

SUBSTANCE: invention relates to trailer-trains with prime mover and one or several trailers. Trailer for use in trailer-train has main chassis made for articulated connection with wheeled part of truck directly before trailer with possibility of turning of wheeled part relative to main chassis around vertical first axle on main chassis. Additional chassis provided with great number road gripping wheels installed on chassis at a distance from each other in longitudinal direction and connected with main chassis for free turning around mainly vertical second axle of main chassis, stop gear adapter for setting maximum angle of free turning of additional chassis from position of alignment in longitudinal direction relative to main chassis depending on positioning of stop gear relative to main chassis. Trailer is furnished also with device for automatically positioning stop gear relative to main chassis at turning of wheeled part around first axle so that maximum angle changes according to positioning of stop gear, and control device responding to relative turning of additional chassis and main chassis around second axle to control at least two said pairs of wheels relative to additional chassis to align additional chassis relative to main chassis in longitudinal direction. Each pair of steerable wheels is installed on fixed axle unit hinge-connected with additional chassis and is made to control, by turning, axle unit around vertical third axle. Axles of rotation of each pair of steerable wheels meet at side of additional chassis at turning of trailer.

EFFECT: improved steerability owing to direction of trailer wheels along track pf primer mover.
