Axle suspension for rigid axles in vehicles

摘要

An axle suspension for rigid axles in vehicles, especially utility vehicles, with longitudinal control arms extending in the longitudinal direction of the vehicle and connecting the vehicle axle to the vehicle body in a vertically movable manner. The longitudinal control arms are arranged for axle guiding on each side of the vehicle approximately at the same level. A four-point torsional connecting element is articulated to the vehicle axle, on the one hand, and to the vehicle body, on the other hand. The four-point torsional connecting element is arranged above the vehicle axle and is connected as a flexible cross to the vehicle axle and to the vehicle body via two body and axle joints located at spaced locations from one another in the transverse direction of the vehicle. The arms of the four-point connecting rod are designed in whole as a one-piece forged part and are girders subject to bending with an approximately rectangular cross section. One of the arms has a predetermined breaking point.
