Zusammenfassung:This invention relates to a rear axle of a vehicle, in particular a passenger vehicle, whose wheel mount is guided by five individual suspension links, at least two of which are coupled above the midpoint of the wheel and at least two are coupled essentially beneath the midpoint of the wheel, and the so-called steering rod as the fifth link is coupled behind the midpoint of the wheel (as seen in the direction of travel). To create a compact configuration, the two upper transverse links are situated in front of a spring element (as seen in the direction of travel) and/or a shock absorber element, which is located between the vehicle body and one of the lower suspension links. To improve the elastokinematic behavior, the steering rod is pitched at an angle of sweep with respect to the transverse direction of the vehicle, this angle being on the order of magnitude of 5° to 25°. The coupling points on the wheel mount side of the two upper suspension links and/or the lower suspension links are offset in height with respect to one another and neither the two upper suspension links nor the lower transverse link and the (lower) frame side bar describes a common plane. All the arms are preferably ultimately linked directly or indirectly to a rear axle mount which forms a supporting frame.
