CHANGING COIL SPRINGS CHARACTERISTICS BY SHOT HARDENING AND GALVANIZING

Ioan VIDICAN, Daniel Gheorghe LAKATOS, Ioan Aurel CHERECHEŞ, Mircea BEJAN

Abstract


The paper analyzes the springs (usually made from bars of constant section), used in vehicle suspension. Depending on the purpose, the material used, the space in which are mounted and by how that will work, the springs are classified in different variants.To meet its goal, must be known relationship between load and deformation of the working spring and finding the action of mechanical work of deformation depending on loading and application point. In operation, in addition to static load, spring is subjected to: uncompensated centrifugal force when passing through curves, wind pressure, the forces of inertia to start and stop the vehicle, vehicle dynamics due to oscillations.

Key words: coil springs, air springs manufactured, shot hardening, galvanizin
