INDEPENDENT WHEEL SUSPENSION OF AN AT LEAST SLIGHTLY STEERABLE REAR WHEEL OF A TWO-TRACK VEHICLE

摘要

The invention relates to an independent wheel suspension of a rear wheel of a two-track vehicle, which wheel can be steered at least slightly by means of an actuator (10). The swivel bearing (2) of said vehicle that carries the wheel is guided by a longitudinal control arm (1), which extends substantially in the longitudinal direction of the vehicle, and by two transverse control arms (21, 22), which extend with a forward and inward sweep predominantly in the transverse direction of the vehicle, are located in different planes when viewed in the longitudinal direction of the vehicle, and the ends of which facing away from the swivel bearing (2) are at least slightly articulated directly or indirectly on the vehicle body. The swivel bearing (2) is hinged to the longitudinal control arm (1) via two joints (6, 7) arranged at different heights when viewed in the longitudinal direction of the vehicle, in such a manner that said joints (6, 7) describe a steering axis of rotation running predominantly perpendicularly in side view and having a negative scrub radius for the wheel, and each transverse control arm (21, 22) is fastened to the longitudinal control arm (1) via a rubber bearing or a joint (21a, 22a) having at least a slight rotational degree of freedom, wherein the swivel bearing (2) is supported on a soft rubber bearing (11) and is furthermore guided by a tie rod (8), which is connected to an actuator element (9) of the substantially centrally arranged actuator (10) that is effective for both rear wheels of the vehicle, said actuator element being displaceable substantially in the transverse direction of the vehicle.
