This invention relates to an independent front axle suspension for passenger cars. The suspension possesses a lower guide member, which is set transversely to the longitudinal direction of the vehicle and is flexibly coupled to the vehicle body, and a shock absorber strut, or spring strut, which is located between this guide member and the vehicle body, on which strut a wheel carrier is retained. This wheel carrier is able to move about a steering axis and is coupled to a steering track rod extending in the transverse direction of the vehicle. The total mass of the front axle suspension is capable of vibrating about an instantaneous rotation axis which extends downwards from the upper coupling point of the shock absorber strut, or spring strut. This axis is orientated in space in such a manner that it intersects the axis of the steering track rod, or crosses this axis, lying at least in close proximity thereto. This association of the instantaneous rotation axis with respect to the steering track rod enables longitudinal forces, which act on the guide member and induce wheel vibrations in the longitudinal direction, to be prevented from becoming effective, any longer, in the longitudinal direction of the steering track rod, at least to the extent of their exerting disadvantageous effects on the steering gear and/or on the steering wheel.

Independent front axle suspension for passenger cars

A ball joint which includes a ball pin that is connected with a coaxial strut, a bearing part of synthetic material, a ball housing surrounding the bearing part, and a bellows seal, particularly as used with front axles of motor vehicles equipped with a braking support. The ball housing is equipped with abutment surfaces which abut at rubber spring elements having a progressive spring characteristic while the rubber spring elements project from an outer housing which has a spacing on all sides from the ball housing.
