SWIVEL HITCH OF A TWO-LINK TRACKED VEHICLE Russian patent published in 2022 - IPC B62D55/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to rotary coupling devices of a two-link tracked vehicle. The device comprises a nose tube, hydraulic cylinders for forced folding of vehicle links, a hitch. The nose tube is fixed on the second link. The hitch is made in the form of a three-dimensional truss, V-shaped in the horizontal and vertical planes. The hinges are placed on the vertices of the specified truss. At the tops of the farm, located at the stern of the first link, hinges with vertical and horizontal axes are made. On hinges with a vertical axis, hydraulic cylinders for forced folding of the links are installed, which ensure the rotation of the vehicle. Hinges with a horizontal axis are connected to the stern of the first link by means of levers, the lower of which are connected to the lower hinges fixed on the stern of the first link. The upper levers are made in the form of composite levers with intermediate hinges, on which hydraulic cylinders are installed for forced folding of the links in a vertical plane. The end parts of the levers are connected to the hinges fixed on the stern of the first link above the lower hinges.

EFFECT: increase in maneuverability is achieved.
