IMPROVED SUSPENSION ISOLATING DEVICE.

摘要

An improved device for isolating a vehicle frame from an axle assembly is provided. This device s characterized such that deflection caused by road shock is severely limited when the vehicle is in a loaded condition and substantially higher when the vehicle is in an unloaded condition. The device comprises an elastomer shear spring; a circular outer ring surrounding the shear spring and mounted to the axle assembly; and inner plunger having a top surface to which a load is applied and a lower portion comprising an elastomer compression spring.
