<p>An axle lift system for a vehicle has a fixed support (12) for an axle lift gas bellows (13), said support being positioned below a bearing arm (3) for the axle (5) as a fixed part of a carrier bracket (1) for this bearing arm (3). The bellows (13) lifts the axle (5) if inflated. The top of the bellows (13) is not rigidly connected to the arm (3), but is connected to the bearing arm (3), the axle (5) or the spring carrier bracket (1) in a point at a horizontal distance from said bellows (13) by a restraining arm (14, 24) limiting horizontal movements of the upper end of the bellows (13). The restraining arm may be a leaf spring (14) or a rigid pivoting arm (24, 25), e.g. pivoting about the same pivot axis (2) as the bearing arm (3) in the carrier bracket (1). This allows free contact between the bellows (13) and the bearing arm (3), so that this arm can have a smooth surface without bolt holes or other deformations for securing the top of the bellows thereto. A rubber-elastic pad (15) may be provided on top of the bellows (13) and of the restraining arm (14, 24) for contact with the bearing arm (3). <IMAGE></p> |
