"Four Point Link For Suspension Of A Rigid Axle"
Abstract: The invention relates to a four point link for the suspension of a rigid axle in particular of a utility vehicle. The four point link has four bearing sockets (3) wherein two bearing sockets (3) can be articulated on the vehicle axle and two bearing sockets can be articulated on the vehicle frame. The four point link here comprises a single piece link body (1 2) which is encompassed by the trapezium formed through the bearing sockets. The four point link is distinguished in that the link body (1 2) is formed from a fibre composite arrangement. The fibre composite arrangement here comprises at least one longitudinal fibre arrangement (10 11). The longitudinal fibre arrangement (10 11) encloses the bearing socket (3) at least along half the circumference thereof and at the same time runs along at least parts of the link body (1 2). The invention makes it possible for four point links to be configured so as to be optimized in terms of loading and for the mass thereof to be reduced while at the same time the application area thereof is extended. A torsional compliance which can be demonstrated specifically makes it possible to use relatively small and/or relatively hard rubber bearings for articulating the four point link and/or the vehicle axle. Furthermore the corrosion resistance and vibration damping are improved the service life is increased and component integration in particular in respect of mounting the four point link on the chassis and axle and attaching the same thereto is enhanced.
