A device for the active adjustment of a motor vehicle wheel comprises an arrangement having an adjuster (4) in which the wheel guiding components are articulated on a wheel bearer (6) below and/or above a wheel axis (11) independently of this arrangement and pivotably held on the vehicle structure. The arrangement has an adjuster connected to the wheel bearer via a track rod (5). The adjuster is movable about a pivot beneath the axis of rotation of the wheel via a track rod joint (9) and a steering link (7) on the wheel bearer side depending upon running parameters for the compulsory alteration of the wheel position. The adjuster of the arrangement consists of at least one hydraulic cylinder which can move inwards and outwards to affect the wheel position via an electronic control unit dependently upon running parameters like the wheel spring travel, transverse acceleration, speed, longitudinal acceleration, deceleration, yawing moment and steering angle. This means that the forces, especially the longitudinal forces, can be accounted for separately through the separate articulation of the wheel guide component on the wheel bearer from the track rod of the adjusting arrangement, so that it is possible to make wheel adjustments like camber, toe-in and toe-out unaffected thereby. There is a faster build-up of lateral forces especially in curves and/or changes in track. |
