ABSTRACT:
An air spring damper used in a vehicle suspension system with upper, intermediate and lower chambers and incorporating a reservoir tube which has an anti-friction rod guide and bearing assembly therein which lubricates the hollow rod of a piston as it strokes in their reservoir tube in jounce and rebound. An elastomeric air sleeve is featured which is connected to a top mount fastened to the vehicle body. An elastomeric isolator of this mount pivotally connects the piston rod to the body while sealing the upper end of the air sleeve. The air sleeve is supported full time by an outer elastomeric sleeve for improved air sleeve operation. A jounce bumper mounted internal of the reservoir tube is compressible to resist and cushion jounce strokes of the piston. This damper provides optimized vehicle body isolation and damping of both body and wheel axle at their natural frequencies.
