A rear frame (4), with two wheels (7,7') and front frame (3), with a single wheel (13), tilt relatively about a longitudinal axis, a tilt angle (Beta) being induced, by a hydraulic cylinder (12), in proportion with the difference in angle (Alpha) between the steering wheel (18) and the front wheel steering axle (15). The steering wheel (17) is coupled to the front wheel (13) via an angle sensor (24) for tilt control. A system of hydraulic control valves and sensors ensure dynamic stability.
