Stellox Leaf Springs

Stellox leaf springThe leaf spring is one of the elastic components of the rigid axle-type suspension of the vehicle. The leaf spring transfers the load from the frame or body to the undercarriage and softens clashes and jolts that occur when driving on a rough surface. The leaf spring may be provided in the construction of both commercial vehicles and passenger cars.

The leaf spring consists of a few metal (steel) sheets (leaves) of the same thickness and width but of different length. They are connected with clamps. The main spring leaf (its thickness exceeds the thickness of the other sheets) is fixed by means of the spring eyes. According to design there are multi-leaf, few-leaf and single-leaf springs.
