Method and device for stabilizing a vehicle against rolling movements

摘要

An anti-rolling stabilizer for a motor vehicle is provided. The stabilizer includes a U-shaped torsion bar having an elongated base and two free ends. The elongated base is coupled to a vehicle frame and each of the free ends is coupled to one of a right-hand and a left-hand wheel-guiding element via a respective coupling bar. Each of the coupling bars includes an NVH vibration absorber configured to counteract vibrations of the respective coupling bar or of the respective wheel guiding element to which the coupling bar is configured to connect, wherein the NVH absorber counteracts vibrations in one or more predetermined frequency ranges without counteracting vibrations in other frequencies.

1. A method for stabilizing a motor vehicle against rolling movements by means of a U-shaped torsion bar, an elongated base of which is coupled to a vehicle frame and free ends of which are each connected via a respective coupling bar to a right-hand or a left-hand wheel guiding element, comprising:
tuning a first vibration absorber configured to be mounted to a first of the coupling bars to counteract vibrations of the first coupling bar or of the wheel guiding element connected to the first coupling bar in one or more predetermined frequency ranges; attaching the first vibration absorber to the first coupling bar such that the first vibration absorber and the first coupling bar vibrate as a unitary mass; tuning a second vibration absorber configured to be mounted to a second of the coupling bars to counteract vibrations of the second coupling bar or of the wheel guiding element connected to the second coupling bar in one or more predetermined frequency ranges; and attaching the second vibration absorber to the second coupling bar such that the second vibration absorber and the second coupling bar vibrate as a second unitary mass.
