Abstract
An axle suspension for a vehicle includes a spring assembly with a leaf spring and a connecting arm, wherein the leaf spring supports a vehicle axle and, on an end side, is pivotably connected to a vehicle structure and pivotably connected to the connecting arm. In order to provide an optimized axle suspension with two-stage suspension, the spring assembly in a region of the connecting arm has a first stop element and the vehicle structure has a second stop element, which stop elements under normal load of the vehicle are spaced apart from one another and, when a limit load is exceeded, contact one another, whereby at least one stop element is elastically deformable.
