Abstract
A leaf spring construction including at least one leaf element made from a flat sheet of uniform width and thickness, the leaf element having an arcuate shape in the transverse cross-section with a convex surface on tension stress side and a concave surface on compression stress side thereof, the leaf element having in cross-section a width b and a transverse center line forming an arc of a radius r.sub.c with the relation of EQU 2.0.gtoreq.r.sub.c /b.gtoreq.0.64 and a thickness t with the relation of EQU 0.2.gtoreq.t/b.gtoreq.0.05 In a laminated leaf spring including a plurality of such leaf elements, each leaf element is formed to have a convex surface of a radius of curvature r.sub.o and a concave surface of a radius of curvature r.sub.i in the relation of EQU 1.2.gtoreq.r.sub.o /r.sub.i .gtoreq.1.0.
