Elliptic spring

nounStandard termMechanical

A suspension component made of two opposing semi-circular leaf springs joined at their ends.

This traditional suspension element consists of curved steel strips bound together to form an oval shape. As a load is applied to the top and bottom centers, the ends push outward, absorbing shocks through the bending of the metal leaves. They were widely used in early railway carriages and heavy wagons before coil springs and dampers became standard.
