Title: METHOD FOR PRODUCING A LEAF SPRING, AND LEAF SPRING AND WHEEL SUSPENSION
Abstract:
The invention relates to a method for producing a leaf spring (1), in particular a leaf spring for a wheel suspension, having at least two attachment components (3) engaging around some sections of the leaf spring (1), wherein the leaf spring (1) is produced from an endless-fiber-reinforced first plastic semi-finished product (5). In order to provide a leaf spring (1), which is characterized by a simpler fabrication and mounting operation, the attachment components (3) are produced from a fibre-reinforced second plastic semi-finished product (6), and the first plastic semi-finished product (5) and the second plastic semi-finished product (6) are connected materially in a fabrication step to form a common component.
