Abstract
A dynamic absorber suspension strut includes a sealed hydraulic damper mounted in an outer tube. An absorber mass is supported on a spring inside the outer tube. The absorber mass divides an interior of the outer tube into first and second fluid chambers. A fluid conduit is provided between the chambers. A control valve controls fluid flow in the fluid conduit to provide a desired damping of wheel hop frequencies. The damper is tuned to provide a desired damping of body frequencies.
