In order to simplify and reduce the production costs as well as increasing the life of plate springs having an annular base body and tongues or arms originating therefrom, in which reinforcing profiles are incorporated at least over subregions, the plate springs are produced from an original material consisting of spring steel which is annealed on spheroidal cementite. The use of such a material makes it possible to incorporate the reinforcing profiles by cold forming, as a result of which the production is considerably simplified. |
