Abstract:
In a vehicle wheel suspension, a first trailing arm is oriented in the longitudinal direction of the vehicle and a second trailing arm in the direction of an angle bisector between the longitudinal and transverse directions. The ends of the trailing arms determine a substantially horizontal instantaneous axis for the wheel carrier relative to the spring jounce and rebound motions of the vehicle chassis. The wheel carrier is slightly pivotable about a toe axis under the influence of braking forces. A support arm securely connects to the wheel carrier and extends over a defined distance substantially in parallel with and supported on the second trailing arm. The support is softer in the horizontal direction than in the vertical direction. A suitable design of the second trailing arm and/or the support arm allows a slight pivot motion of the wheel carrier about the toe axis.
