Suspension system for a vehicle including an accumulator

摘要

Suspension system for a vehicle is disclosed and claimed. The suspension system includes a fluid, a suspension strut, a hydraulic cavity, an accumulator, and a volume modulator. The hydraulic cavity is at least partially defined by the suspension strut and is adapted to contain a portion of the fluid. The hydraulic cavity supplies a suspending spring force that biases a wheel of a vehicle toward the road surface. The volume modulator selectively pushes the compressible fluid into the hydraulic cavity and vents the compressible fluid from the hydraulic cavity, thereby actively modulating the suspending spring force.
