To combine a low amount of space for a driven axle with precisely calculated track and- camber alterations and the steering effects during spring compression.
If one imagines two double wishbones as four individual guides and adds the connection to the tie-rod, one can arrange these five guides relative freely in the available space, thus obtaining the multi-link suspension. Mostly these are not connected by rubber bearings directly with the bodywork, but with a connecting construction (suspension subframe). In addition, one of these guides also takes up the (mostly coil) spring and the shockabsorber. The relatively complicated construction demands only little space in front of the rear axle, leaving a safe and secure location for the fuel tank. Depending on the length and position of each individual guide and through the choice of rubber compound on the pivot points, the wheel alignment can be altered according to the spring travel and the demands made.
