Abstract
The outer profile of the spring is shaped to control breakover (i.e., the change in spring deflection from constant to rising rate) and spring rate. A process for inducing breakover in thick-walled elastomeric springs which normally have no breakover, and for controlling breakover, whether so induced or occurring naturally, as well as spring rate, is disclosed.
