ABSTRACT:
Annular coil spring apparatus is provided which includes a first annular spring with a plurality of coils canted along a centerline with a trailing portion of each coil and a leading portion of each coil defined by a back angle and front angle, respectively. Coils are interconnected in order to form a garter-type coil spring and a second annular spring is provided and disposed within the first annular spring. The second annular spring may include a plurality of coils canted along a centerline thereof and the first and second annular spring may be canted in either the same direction or opposite directions in order to provide different force-deflection characteristics of the annular coil spring apparatus.
