Abstract

The invention relates to an axle suspension means for motor vehicles, wherein the guide means of a rigid axle is constructed so that the latter changes its position in the sense of a positive oblique springing during inward spring stroke movements, and executes no inherent steering movements during one-sided and alternate-side inward and outward spring strokes. For this purpose the rigid axle is guided on each side by a pair of guiding control arms which determine, for its wheel axis, a pivot axis about which the wheel axis is movable by means of a guide arm retained on the vehicle body in the sense of the positive oblique springing during inward spring stroke movements. Simultaneously, the two pairs of guiding control arms, each in common with a rocker arm mounted on the rigid axle pivotably about the pivot axis staggered vertically to its wheel axis, form straight guides guiding the pivot axis in a vertical plane during inward spring stroke movements, whereby inherent steering movements of the rigid axle are prevented.
