Multi-link suspension

Rear viewTop viewA multi-link suspension is a type of vehicle suspension design typically used in independent suspensions, using three or more lateral arms, and one or more longitudinal arms. A wider definition considers any independent suspensions having three control links or more multi-link suspensions. These arms do not have to be of equal length, and may be angled away from their 'obvious' direction. It was first introduced in the late 1960s on the Mercedes-Benz C111 and later on their W201 and W124 series.5-link rear wheel suspension mechanism (front view)5-link rear wheel suspension mechanism (top view)5-link suspension mechanism with rack-and-pinion steering input (front view)5-link suspension mechanism with rack-and-pinion steering input (top view) A multi-link suspension is a type of vehicle suspension design typically used in independent suspensions, using three or more lateral arms, and one or more longitudinal arms. A wider definition considers any independent suspensions having three control links or more multi-link suspensions. These arms do not have to be of equal length, and may be angled away from their 'obvious' direction. It was first introduced in the late 1960s on the Mercedes-Benz C111 and later on their W201 and W124 series. Typically each arm has a spherical joint (ball joint) or rubber bushing at each end. Consequently, they react to loads along their own length, in tension and compression, but not in bending. Some multi-links do use a trailing arm, control arm or wishbone, which has two bushings at one end.
