The multi-link axle, each wheel is suspended on multiple (up to five) arms. This is a relatively complex spatial mechanism, which ensures optimal axle kinematics. Multilink suspension can be used as front and rear as in both cases can be driven or driving. Multilink suspension is considered the best design compromise responsive ride. Its design and production is unfortunately difficult, and this is reflected in the price and then in the profitable use.
Multilink suspension is independent suspension , which is implemented using several arms (arm bar or triangle). The front multilink suspension was actually modifying keystone correction . As an example to describe this type of axle five-link front axle bearing, as shown. Wheel suspension is implemented through five pole arms. Shock absorber with coil spring over the support arm transmits forces from the roadway into the body. Thanks to the mutual independence of all suspension arms can be achieved optimal kinematic motion wheels. Number of wings and their location can achieve high accuracy and responsive ride, see the second picture.

Another example of using multi-link axle rear suspension, for example to drive 4 × 4 The picture below is the rear axle Skoda Octavia 4 × 4 The wheels are mounted with two towing arms and four cross arms. Such a solution allows the separation of longitudinal and transverse forces transmitted from the wheels to the body. Hanging in the transverse direction is very rigid, which improves cornering stability, but quite flexible in the longitudinal direction, which contributes to greater travel convenience. Vertical forces are captured by a spring and a damper that can be stored near the wheels and the limited size of the boot. Integral V rear axle is usually (as well as the front) equipped with torsion stabilizer, which reduces body roll in corners.

For example. Porsche Cayenne rear multilink suspension is composed of longitudinal and transverse stiff shoulder is saved in the axle. Such design facilitates installation into the vehicle axles and suspension stiffness increases.
