Abstract
A suspension system for a vehicle having a vehicle body and a road wheel includes a suspension corner connecting the road wheel to the vehicle body. The suspension corner maintains contact between the road wheel and a road surface. The suspension system includes a bladder arranged at the suspension corner for pumping a fluid in response to forces generated at the wheel and holding a volume of the fluid. The suspension system also includes an accumulator in fluid communication with the bladder for selectively accumulating the fluid pumped by and releasing the fluid to the bladder. The suspension system additionally includes a valve for selectively retaining the accumulated fluid in and releasing thereof from the accumulator. The height of the bladder varies in response to the volume of fluid being held by the bladder to set a ride height of the vehicle at the suspension corner.
