Integral Suspension System for Motor Vehicles Based on Passive Components

This paper presents the theory and results of a passive suspension system implementation that links the four wheels vertical movements through a central device. This arrangement is made to define a passive kinematics link between all wheels vertical movements that define the elasticity and damping of all vehicle movements, roll, pitch and rebound, as well as the resistance to axle crossing.

The analisys made is opposite to the traditional one-quarter-vehicle analisys, and exploits the passive systems to provide advantages sought with active systems.
