A suspension system with inclination stabilization, in particular for use on heavy work vehicles, such as a dumper, where the front pair of wheels is mounted on a transverse rigid axle, has an axle (5) firmly connected with a Y-shaped frame (1) extending in the longitudinal direction along the central line (M) of the vehicle. The frame is suspended from the chassis of the vehicle, partly from a spherical bearing (4) disposed in the central line of the vehicle, partly via two spring units (2, 3) arranged symmetrically around the central line and a rod connection (7). The frame is additionally equipped with one or more laterally directed stabilization arms (6) which are confined by the chassis. This provides a suspension system which contains a very small number of components, which is stable, sturdy and resistant to wear, and which contains both springing, level adjustment and inclination stabilization.
