Patent attributes
A pneumatic suspension system may include, for each wheel of a vehicle, a strut and an adjustment cylinder in fluid communication with the strut. Adjustment cylinders associated with an end of the vehicle may be mechanically coupled while keeping the cylinders isolated pneumatically. A suspension control system can control fluid flow at each of the adjustment cylinders to selectively engage or disengage an anti-roll feature. By allowing fluid flow at the adjustment cylinders, the struts are free to oscillate in response to forces at the associated wheel, e.g., caused by an uneven road. By inhibiting fluid flow at the adjustment cylinders, forces experienced at the struts can be transferred between multiple struts. In some examples, the fluid flow at the adjustment cylinders can be controlled to vary the travel distance of the struts, to selectively provide a stiffer or looser suspension.
