Leaf-spring

A method of manufacturing a leaf spring to be clamped between a saddle of a vehicle axle and a clamping plate by means of connecting elements spaced from one another in a longitudinal direction, the method comprising the steps of

• providing at least one elongated spring member extending in the longitudinal direction and being composed of a fiber-reinforced duroplastic synthetic plastic material and having two sides;
• covering each of said sides of said spring member with a fiber-reinforced duroplastic protective layer;
• covering each of said sides of said spring member with a thermoplastic cover layer;
• removing the cover layers in the region between the connecting elements completely;
• removing the protective layers in the region between the connecting elements partially;
• providing two supporting plates;
• connecting each of said supporting plates with pressure cushions of a rubber-elastic material;
• and
• connecting the supporting plates together with said pressure cushions, and with said sides of said spring member so that said pressure cushions are located between the spring member and the supporting plates.
