ABSTRACT:
An elastomeric spring useful as an automotive shock or strut end-of-travel bumper having at least three distinct spring rates made possible by a series of roughly cylindrical, hollow elastomeric tubes stacked with the axes of the tubes normal to the axis of deflection of the spring. The tubes collapse sequentially to yield multiple spring rates. Non uniform wall thickness tubes, roll axially over the outer peripheral surface of the thicker walls of adjacent tubes during deflection.
