Four-point link

A method of producing a four-point link, for a wheel suspension of a vehicle, having a core element, a thread or a plurality of parallel threads and four bushings, each thread being pre-impregnated with a resin, the core element having a torsional element and four supporting arms, and a bushing being arranged, on each respective distal end of the supporting arms, for holding a respective bearing element, the method comprising:

• producing the core element such that the four supporting arms are integrally connected to the torsional element,
• connecting each respective bushing to a respective distal end of the supporting arm concerned,
• at least partially wrapping the core element and the respective bushings with the pre-impregnated thread to form at least a frictional connection between the bushing concerned and the thread,
• forming cutouts in the core element that accommodate a plurality of thread cross-over points to maintain a consistent material thickness of the torsional element, and
• forming a plurality of contact surfaces on the core element that extend laterally relative to a longitudinal axis of the four-point link and support turning points of the thread.

A four-point link for a wheel suspension of a vehicle, the four-point link comprising:

• a core element having a torsional element and four supporting arms being integrally connected to the torsional element, and each of the four supporting arms extending from the torsional element and having a distal end, and the core element defining a longitudinal axis of the four-point link;
• four bushings being coupled to the distal ends of the four supporting arms, respectively, and the four bushings being arranged for respectively supporting bearing elements;
• at least one thread being pre-impregnated with a resin, and the at least one thread being wrapped around the torsional element and the four supporting arms of the core element and the four bushings to at least frictionally connect the bushings and the at least one thread;
• the core element has two cutouts located on opposite lateral sides of the longitudinal axis of the four-point link, the two cutouts reduce a material thickness of the torsional element and accommodate a plurality of cross-over points of the thread to maintain the material thickness of the torsional element consistent;
• and
• the core element has a plurality of flattened contact surfaces that support turning points of the thread and extend laterally relative to the longitudinal axis of the four-point link.
