A wheel suspension for an axle of a motor vehicle has a transverse control arm and tension strut, the transverse control arm being held on the wheel carrier by way of a joint, and the body-side bearings of the transverse control arm and of the tension strut as well as of the connection bearing between the transverse control arm and the tension strut being constructed with a defined characteristic for the elastokinematic adjustment of the wheel under the effect of lateral and peripheral forces acting upon the wheel. The transverse control arm with the connected tension strut is arranged below a wheel drive shaft and--with respect to the driving direction--in front of a tie rod. In the top view, the tension strut extends diagonally toward the front, the transverse control arm and the tie rod having a positive position with respect to one another. They form a wheel steering pole situated outside the track width and behind the wheel center transverse plane. In front of the wheel center transverse plane and outside the wheel center longitudinal plane, a point of intersection is formed through an axis extending through the wheel-carrier-side joint of the transverse control arm and the body-side bearing of a McPherson spring strut or, alternatively, of an upper side double arm and spring strut assembly.

Wheel suspension system with elastokinematic wheel adjustment

A wheel suspension for an axle of a motor vehicle, particularly a McPherson front axle, has a transverse control arm and a pivotally connected tension strut, the transverse control arm being held on the wheel carrier by way of a joint, and the body-side bearings of the transverse control arm and of the tension strut as well as of the connection bearing between the transverse control arm and the tension strut being constructed with a defined characteristic for the elastokinematic adjustment of the wheel under the effect of peripheral forces acting upon the wheel. The transverse control arm with the connected tension strut is arranged in an approximately horizontal plane and extends below the wheel spin axis approximately in a wheel center transverse plane. The tension strut is pivotally connected to the transverse control arm by way of a connection bearing and extends at an angle diagonally with respect to a longitudinal center axis of the vehicle. The transverse control arm is arranged, in each case, at a distance in the perpendicular and longitudinal direction with respect to a tie rod of a steering gear arranged below the wheel spin axis and--with respect to the driving direction--in front of the transverse control arm.
