FIELD: transport engineering.

SUBSTANCE: invention relates to articulated vehicles, namely, to coupling gears. Proposed draw-and-weight transfer device contains hitch member connected with tie-rods and coupled with mating member secured on drawbar of semi-trailer with possibility of automatic adjustment of position of upper tie-rod. Tie-rod are connected with tractor by means of Hooke's joints. Vertical axles of rotation of Hooke's joints are found on tractor, and horizontal ones, on tie-rods. Hook's joints are arranged so that their vertical axles of rotation are located on one axial line.

EFFECT: provision of constant transfer of part of weight of semi-trailer to base of tractor with loading force applied at level of support surface and automatic control of degree of load transfer to tractor when moving along horizontal surface, and negotiating slopes and up-grades.
