Abstract

An individual wheel suspension for a non-steered wheel of a motor vehicle, such as an automobile, is disclosed. The suspension comprises a trailing arm, connected with the vehicle body in an articulated fashion by means of a lengthwise arm disposed in the direction lengthwise of the vehicle and, in the direction transverse to the vehicle, by means of two wishbones, one located above the other, whereby the wishbones form auxiliary tie-rods in a transverse plane running vertically through the wheel center, the extensions of the tie-rods, directed toward the center of the vehicle, intersecting at a transverse pole located at a distance from the wheel center plane. The auxiliary tie-rods, with their articulations at the wheels are provided in the vicinity of the wheel center plane at an auxiliary distance from the transverse pole whereby the wishbones each form an auxiliary tie-rod with a length which is shorter than or approximately equal to half the auxiliary distance. The lengthwise arm is disposed so that it points toward the rear of the vehicle, with an articulation of the lengthwise arm to the vehicle body being located near the wheel center plane and beneath the center of the wh…
