Abstract
The Leaf Spring consists of several leaves. Its load-deflection curve shows hysteresis because of the friction between leaves. Since this hysteresis loop affects the driving comfort and stability of vehicle, this is one of the most important factor for designing leaf spring. In this paper, the effects of type of eye, eye diameter, and edge shape of No. 2 leaf to the friction on histeresis loop were experimentally studied.
It was found that combining berlin eye of No. 1 leaf with curved edge of No. 2 leaf can control the increase of dynamic spring-rate under the low deflection area.
It was also realized that this effect can improve the driving comfort of vehicle.
