The Multi-Link Suspension
The most important thing to know about Multi-Link Suspension is that it's an indipendent one
Derived from the double wishbone one, the multi-link suspension uses three or more lateral arms and one or more longitudinal arms, which don't have to be equal lenght and can be angled away from their natural direction.
Each of the arms has a spherical joint or rubber bushing at each end, causing them to ''work" in tension and compression and not in bending.
The arms are joined at the top and bottom of the spindle turns for steering, it actually alters suspension's geometry by torquing all suspension arms.
Multi-Link arrangement are used on both the the front anf the rear suspension, but he former replaces a lateral arm with a tie-rod that connect the rack or steering box to the wheel hub.
