An individual wheel suspension for a non-steered wheel of a motor vehicle such as an automobile comprises a trailing arm including a lengthwise arm directed along the length of the vehicle, the trailing arm being articulated to the vehicle body by means of the lengthwise arm as well as two wishbones which are arranged transversely to the length of the vehicle and are located one above the other wherein at least the articulation of the lengthwise arm is an elastic bearing. The suspension is characterized in that the articulation of the lengthwise arm is disposed in the vicinity of the wheel center plane with the articulations of the wishbones on the body side being on one side of the wheel axle as viewed from above, and in that the articulations of the wishbones on the wheel side as viewed from above lie approximately on an auxiliary tie rod which runs centrally through the articulations of the wishbone on the body side and at least approximately through the intersection of the application lines of the force along the wheel and laterally with respect to the wheel. Wherein, the articulation of the lengthwise arm to the vehicle body is an elastic bearing with different spring rates C.sub.1 and C.sub.2 in directions which are approximately horizontal and approximately perpendicular with respect to one another, and wherein the direction of the first spring rate C.sub.1 is primarily transverse to the length of the vehicle and forms an angle which is different than 90.degree. with the force which results and acts upon the elastic bearing as viewed from above.

Individual wheel suspension for non-steered wheels of motor vehicles,

An individual wheel suspension for a non-steered wheel of a motor vehicle such as an automobile exhibiting a change in camber of the wheel during spring deflection comprises a trailing arm which is connected to the support for the wheel and articulated to the vehicle body by means of a lengthwise arm disposed in a lengthwise direction of the vehicle and in a direction running transversely to the vehicle by means of two wishbones located one above the other. The wishbones form auxiliary tie rods in a transverse plane running vertically through the center of the wheel, the extensions of the tie rods, running toward the center of the vehicle, intersecting at a transverse pole located at a distance from the wheel center plane. The individual wheel suspension is characterized in that the auxiliary tie rods have articulations to the support for the wheels and are provided in an additional distance determined relative to the transverse pole in the vicinity of the wheel center plane, in that the auxiliary tie rod of the lower wishbone is made at least approximately half as long as the additional distance and the upper wishbone forms an auxiliary tie rod whose length is less than or equal to that of the lower auxiliary tie rod, and in that the lengthwise arm is arranged pointing forward in the direction of travel of the vehicle with the articulation of the lengthwise arm to the vehicle body being located above the axle and in the vicinity of the wheel center plane.

Individual wheel suspension for non-steered motor vehicle wheels

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 wheel.
