Suspension device for a motor vehicle and its implementation
First Claim
1. Suspension device for a vehicle provided with four rolling arrangements, wherein the suspension device cooperates with or substitutes for an existing suspension and defines a kinematic and dynamic relationship between vertical movements of each rolling arrangement, said vertical movements including opposition to roll, pitch, vertical rebound, and axle crossing movement, in order to allow a weight distribution on every rolling arrangement, wherein said rolling arrangements comprise cylinders of simple effect which pistons are not provided with choke valves, said cylinders being connected by their single fluid containing chamber to a central device (CD) by fluid conduits;
- wherein the central device is attached to the vehicle body, receives forces originated in each rolling arrangement, and interacts with and transmits the forces selectively to one or more rolling arrangements, either in a direct or indirect way,the central device comprises two diagonal arrangement elements, each diagonal arrangement element comprising two different diameter double pistons that can freely move inside co-centric cylinders, comprising cylinders equal in diameter to the double pistons, wherein the co-centric cylinders define three cavities, an end cavity of a larger diameter side that is connected to an expansion chamber and two cavities that are respectively connected to diagonally opposed rolling arrangements;
wherein the end cavities of each of the diagonal arrangements are connected to one another through a valve.

Abstract
Vehicle suspension system applicable to vehicles provided with rolling arrangements that have a resistance to the roll, pitch vertical rebound, and axle crossing movement such that allows a weight distribution on every rolling arrangement. The rolling arrangements are connected to a central device that is attached to the vehicle body. The central device includes elastic devices that receive the movements and forces originated in each rolling arrangement because of the weight variations and dynamic forces created when the vehicle is traveling. Vertical forces and movements detected in the vehicle wheels are transmitted to the central device through hydraulic and/or mechanical devices.
