Suspension arrangement, steering linkage arrangement and method for providing variable wheel track

摘要

The invention relates to a method for wheel track adjustment for a steerable vehicle wheel arrangement, which arrangement includes a steering actuating mechanism, a controllable lever arm (20) having a pivot on a suspension control arm (10), which control arm is pivotably attached to the vehicle at a first end and is provided with a ball joint (11) that is pivotably attached to a wheel hub (2, 3) at a second end, and a pair of connecting rods (23, 24) pivotably connected to the lever arm (20) on opposite sides of the pivot of the lever arm (20) and to the wheel hub (2, 3) on opposite sides of the ball joint (11). Actuation of the lever arm (20) causes the connecting rods (23, 24) to displace the ball joint (11) a predetermined distance along an axis substantially transverse to a central longitudinal axis (X) of the vehicle, which distance is proportional to a vehicle wheel steering angle (αI, αO). The invention further relates to a suspension arrangement for a steerable vehicle wheel and a steering linkage arrangement therefore.
