摘要：
A variable rate elastomeric torsion spring 30 includes a generally cylindrical elastomeric member 36 having an outer shell 34 bonded thereto on the outside and a plurality of adjacent, axially aligned inner sleeves 36, 38 bonded thereto on the inside. A variable spring rate is obtained by the spring by selectively engaging different combinations of the inner sleeves.
