Abstract
A system and methods are provided for a suspension system of an off-road vehicle that allows the springs to be mounted remotely, in any location on the vehicle, enabling the use of spring sizes, spring rates, motion ratios, and damping profiles that would be impractical with traditional suspension designs. The suspension system includes a hydraulic cylinder coupled between a suspension component and a chassis, in lieu of a conventional spring. The hydraulic cylinder is in fluid communication with another, second hydraulic cylinder, by way of a hydraulic hose. The second hydraulic cylinder presses against a suspension spring that is in contact with a fixed spring stop, thereby transferring spring forces to the wheel. Alternatively, the spring stop may comprise a control actuator that moves, enabling active control over spring load.
