The invention relates to an arrangement for dampening, or counteracting, lurching of a vehicle chassis in the event of one of the wheels (3'') of a wheel pair (3) and its axle moves over an irregularity (10) in an otherwise horizontal vehicle supporting surface (11). Each of the wheel axles (3a', 3a'') can by adjusted towards and away from the vehicle chassis (1) in a vertical direction by means of a respective hydraulic piston-cylinder-device (6, 7). The transverse level of the chassis in relation to the horizontal is detected by a level-sensing device (12) which is connected to a hydraulic circuit. In accordance with deviation of the sensing device from a horizontal plane, either one or the other of the piston-cylinder-devices (6 or 7) is placed under pressure so as to urge one wheel (3') and its associated axle (3a'') downwards and therewith raise an adjacent chassis part (1a) towards a horizontal position. In the case of a minor deviation from the horizontal plane (4'), the level-sensing device (12) functions to activate a check valve and therewith open a line (20) which extends between the two piston-cylinder-devices (6, 7), whereupon the higher pressure prevailing in one of the piston-cylinder-devices (7) will pass over to a similarly located space in the other piston-cylinder-device (6). |
