ABSTRACT:
There is disclosed a rolling lobe fluid spring (10) having a rigid end cap (12) and a piston (14) with a generally tubular air impervious flexible membrane (18) sealingly attached thereto to form the air spring. A fabric restraining cylinder (40) is provided circumferentially around the outer periphery of the flexible membrane. The cylinder is composed of at least two layers of fabric (41, 42) having primary cord reinforcements oriented at opposite bias angles such that the cylinder (40) is radially extensible and supports the rolling lobe (32) of the air spring. It also radially supports the flexible membrane (18) over the axial working stroke (WA).
