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.

Suspension system for rigid vehicle axle

A tire pressure control system having a pressure switch installed in a rim, which pressure switch, as part of a tuned circuit, damps, across an air gap, an HF transmitter, installed in a wheel web and having downstream analysis electronics, the pressure switch having a diaphragm pressure cell with a reference pressure, the diaphragm of which reference cell is subjected on one side to the reference pressure and on the other side to the tire pressure. A valve installed in the pressure switch makes it possible to adjust the reference pressure so that, when filling the tire, the desired tire pressure is simultaneously retained as the new reference pressure in the diaphragm pressure cell for the tire pressure control system.
