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

An exterior lateral side rail in the area of a passenger compartment is adjoined in the forward structure and/or rearward structure of a vehicle by additional side rails which, in particular, are provided with a right-angle bend. Elements that reinforce the vehicle body are connected with the side rails at one end of the elements, and with an underbody or underbody components at the other end of the elements. The reinforcing elements include a first V-shaped strutting which extends in an approximately horizontal plane in the longitudinal direction of the vehicle and which is connected with a second V-shaped strutting which is arranged in an approximately perpendicular transverse plane. By its free ends, the first strutting is fastened to the side rails and, by its opposite ends, it is fastened to the second strutting at a common connection area. The second strutting is supported by its free ends on the side rails.
