Abstract

A single-pivot suspension strut axle for a passenger car, includes a wheel carrier/pivot bearing carrying the wheel and a brake disk non-rotatably connected with the wheel relative to a rotational axis thereof. A suspension strut is fastened to the wheel carrier/pivot bearing and, at another end, is supported at the vehicle body. The wheel carrier/pivot bearing is guided by a supporting joint situated close to the wheel center plane by a lower control arm, representing an A-arm, and by a tie rod. A section of the control arm connected with the supporting joint projects through the ring-shaped brake disk. A leaf spring element oriented in the transverse direction of the vehicle provides proportional support for the vehicle body on the wheel, and is supported, on one side, at the control arm and, on another side, directly or indirectly, at the vehicle body.
