Abstract: A multi-section shock-linked vehicle suspension system is disclosed that transfers force from one point to another point in a system of interrelated shock absorbers. Force can be transmitted from one shock absorber to another using hydraulics or a gas such as air or nitrogen in a space-efficient form factor, without the use of levers and mechanical force transfer rods. The hydraulic or gas force can be tuned using valves to provide different suspension characteristics. The multi-section shock-linked system provides the ability to share wheel loads across the vehicle by using shock absorbers that are shared in addition to the individual shock absorber associated with each wheel.
