Turning articulation device for road vehicles with at least two vehicle portions connected by means of a pivoting articulation wherein the vehicles may be in a stationary state, or in a stable or unstable motion. The pivoting articulation is connected to a hydraulic control device. The rotating articulation device has a cylinder (5) connected to one of the vehicle portions (3, 4). The inner wall (6) of the cylinder is formed with stop bars orientated inwardly. These cross bars are contiguous to a shaft (8) coaxial to the cylinder (5). Blades (9) are extended radially up to the inner wall (6) of the cylinder (5) and are conformed so as to form a cavity (10) between the inner wall (6) and the shaft (8). Said cavity has a circular ring-shaped cross section divided in pressure chambers (11, 12, 13, 14) by the stop bars (7) and the blades (9). Within said chambers, a pressure fluid may be injected by the control device. |
