<p>A plastic leaf spring with spring-eyes at the spring-ends has a spring-eye section (1) or a spring-eye body (15, 28) of fiberreinforced plastic, with the spring-eye section (1) is integrated in the leaf spring body or the spring-eye body (15, 28) is manufactured separately from it. The spring-eye section (1) or spring-eye body (15, 28) contain each a layer (2, 16, 29) of essentially constant thickness with a center section (4, 18, 31) wrapping the spring-eye opening, and two connecting sections (3, 17, 32) appropriately essentially parallel to each other, with the outside surface of the layer (2, 16, 29) forming a hollow groove (13, 24, 33) at at least one transition between the center section (4, 18, 31) and the connecting sections (3, 17, 32). The strength of the plastic leaf spring according to the invention is substantially increased through appropriately plate-shaped reinforcing elements ( 11, 22, 34) form-locking and/or frictionally connected to each other, which at the outside adjoin the connecting sections (3, 17, 32) under pressure, and of which at least one touches the layer-surface also at a hollow groove (13, 24, 33).</p> |
