Abstract
Abstract An independent wheel suspension for vehicles wherein the vehicle wheel is guided by means of upper and lower transverse wheel forks mounted at the vehicle frame so as to be pivotable about at least approximately horizontal axes. The lower transverse wheel fork is connected directly to the vehicle frame, while the upper transverse wheel fork is connected to the vehicle frame by means of a two-armed deflecting guide member. A torsion bar can be arranged in the longitudinal direction of the vehicle for wheel springing and can be disposed in the extension of the frame-side pivot axis of the lower transverse wheel fork.
