FIELD: transportation.
SUBSTANCE: this invention relates to the technology of articulated chassis of an articulated vehicle. Articulated chassis system comprises a front frame, a rear frame, an annular bearing connecting said front frame and said rear frame, and a hydraulic damping device. Hydraulic damping device comprises a hydraulic cylinder, an oil tank and a hydraulic control oil circuit formed between the hydraulic cylinder and the oil tank. Hydraulic cylinder is equipped with a piston and a piston rod. Piston divides the hydraulic cylinder into the rod end and rodless cavity.
EFFECT: more precise control of the damping of the hydraulic buffer during the rotation of the vehicle is achieved in order to make the movement of the articulated system more stable, and also to restore the vehicle from a turning state to a forward running state faster and safer.
