Abstract:
1. A wheel suspension for a wheeled vehicle having independent suspension, the wheel suspension comprising: at least one lower, wheel-carrying radius arm with an inner end, which is designed for fastening so that it can pivot about a substantially horizontal axis in a vehicle frame, and an outer end, which is pivotally fastened to a lower part of a wheel hub, and at least one upper support arm, one end of which is fastened to an upper part of the wheel hub, and the other end of which is pivotally connected to a part of the vehicle fixed to the frame, wherein: the wheel suspension is part of an independent suspension system, the inner end of the lower radius arm is designed for pivotal connection to the vehicle frame by way of a lower arm part of a double rocker arm, which is aligned substantially vertically and swivels about a substantially horizontal axis, whilst the upper support arm is pivotally connected to an upper arm part of the double rocker arm via a connecting link, which is pivotally connected both to the upper support arm and to the upper arm part of the double rocker arm, so that in the event of a compression movement of the wheel hub, the upper support arm, by way of the connecting link and the double rocker arm, displaces the inner end and thereby the entire lower radius arm inwards, in the event of a rebound movement of the wheel hub, the wheel hub is displaced outwards, in order to minimize the changes in track width in both compression and rebound movements of the wheel hub, and the double rocker arm has a pivotal connection point located between the upper arm part and the lower arm part.
