AIR SPRING WITH FABRIC RESTRAINING CYLINDER

摘要

AIR SPRING WITH FABRIC RESTRAINING CYLINDER There is disclosed a rolling lobe fluid spring (10) having an upper retainer (12) and a piston (14) with a tubular air impervious flexible membrane (18) sealingly attached thereto to form the airspring. A radially inextensible fabric restraining cylinder (40) is provided circumferentially around the outer periphery of the flexible membrane. The cylinder (40) shrouds the membrane (18) over at least the entire axial working stroke (WA) of the airspring. The cylinder (40) radially supports and protects the flexible membrane (18).
