ROAD-TRAIN TRAILER Russian patent published in 2018 - IPC B60P3/40 B62D13/02 B62D53/06 

FIELD: transportation.

SUBSTANCE: trailer truck contains a swivel truck and a trolley mounted on axles with wheels. Swivel truck is equipped with a controlled swivel block, on which the trolley rests on its front end. Trolley is equipped with a supporting platform with a device for fastening long loads. Supporting platform is installed on the trolley also by means of a swivel block. Swivel truck is connected to the supporting platform of the trolley by a pull-rod. Pull-rod is fixed on the swivel truck with displacement relative to its longitudinal axis and on the supporting platform of the trolley with displacement relative to the axis of the swivel block. When the truck is rotated, the load securing device located on the trolley of a road-train trailer rotates together with the long cargo attached to it. Load securing device rotates at the same angle and transmits the torque through the swivel block and pull-block to the controlled swivel block of the swivel truck.

EFFECT: invention is aimed at increasing the maneuverability of a road-train, regardless of its length, and ensuring that the trailer of the road-train is moving as close as possible to the path of movement of the tractor during curvilinear movement.
