Abstract
A dry viscous spring damper is provided particularly adapted for absorbing shocks, dissipating energy and load carrying and leveling of a vehicle. The spring damper is comprised of a first housing member at least partially received in a second housing member and joined at the second housing member with an elastomeric shear spring. The spring damper has a first chamber separated from a second chamber by an elastomeric diaphragm. A valve is provided for selectively pressurizing the second chamber with pressurized gas or air. A plurality of elastomeric particles are included in the first chamber whereby relative movement between the housing members operates to stress the shear spring and the elastomeric particles, and vary the volumes of the first and second chambers.
