  • Patent number: 11156259
    Abstract: Described is a fibre composite component designed as a spring, comprising at least one spring section and at least one force transfer structure (2). In the end portion forming or surrounding the force transfer element (3) the fibre composite material of the fibre composite component (1) is divided, in a plane perpendicular to the longitudinal direction of the force transfer structure (2), into at least two fibre composite material strands (4, 4.1, 4.2). Two adjacent fibre composite strands (4, 4.1, 4.2) run in opposite directions, overlapping over a specific angular portion and each forming an eye, with their mutually opposed side faces (7) force-transmittingly connected in the overlapping portion.

    Abstract: The present disclosure relates to a method for producing a leaf spring 1 for a vehicle axle suspension, wherein the at least one spring arm 5 bordering on a clamping portion 2 is formed from a rod-shaped preliminary material 7, 8 by a rolling process. By the rolling process for shaping the leaf spring a preliminary material rod 7, 8 having a rounded cross-sectional geometry is rolled out to produce a rectangular cross-sectional geometry in the clamping portion 2 and in the at least one spring arm 5, and thus the portion of the preliminary material rod 7, 8 provided for forming the clamping portion 2 in the finished leaf spring 1 is also reshaped by the rolling process and as a result a rolled structure is also formed therein.
