Abstract:
A leaf spring (1), characterized by comprising:a central core (2) made of a first polymer material of predetermined mechanical characteristics and having no reinforcing fibers, said central core (2) being of a shape corresponding to said leaf spring (1) when undeformed, and being defined by two opposite longitudinal, elastically bendable work surfaces (3, 4), and by two lateral sides (5) connecting said work surfaces (3, 4); at least one cover (19) for covering said central core (2) and made of a composite material comprising a polymer matrix incorporating a number of one-way reinforcing fibers, said at least one cover (19) for covering said central core (2) being located on at least one of said work surfaces (3, 4) of said central core (2); and a predetermined number of transverse holes (20, 21, 22) formed through said central core (2) of polymer material and by which to fasten said leaf spring (1) to respective mechanical members, said transverse holes (20, 21, 22) being formed through said sides (5) of said central core (2) so as not to intersect said at least one cover (19) of composite material.
