  • Patent number: 9168801
    Abstract: A transverse link made of fiber-reinforced plastics material for a wheel suspension, which transverse link is pivotable on its bearing elements about a common pivot axis or axes running substantially coaxially with respect to one another, these bearing elements being connected by a single-shell connecting element having connecting arms to a bearing element having a ball and socket joint bearing. The bearing elements and the connecting element are elements of an integral plastics material. In order to produce a transverse link of this type, disclosed is an integral plastics material moulded part produced by extrusion of plastics, the bearing elements having bearing bushes shells surrounded by extrusion of the plastics material. The ball and socket joint bearing have a bearing bush or a shell-shaped sliding capsule, produced from plastics material and connected to the connecting element, the connecting element comprising a centre or transverse web connecting the bearing elements.

  • Patent number: 9090138
    Abstract: The invention relates to a single-shell spring control arm, for a wheel suspension of a motor vehicle, comprising a first end portion for attaching to a chassis beam a second end portion for attaching on the wheel side, and an increased-width portion which is arranged between the two end portions, and which comprises a spine having flanks projecting therefrom and which defines a spring seat for supporting a spring. In order to attain high component rigidity and a wheel suspension which is optimized with regard to loads, the invention proposes that inwardly deformed surface parts are formed on the flanks, the longitudinal edges of which surface parts are spaced apart from one another along their entire length so that the increased-width portion has a C-profile-shaped cross-sectional profile, and in that a connection portion for attaching a shock absorber is formed between the spring seat and the second end portion.
