Abstract
A roll stabilizer for a motor vehicle includes a torsion bar and a vibration damper located on the torsion bar. The vibration damper is configured to vibrate relative to the torsion bar. The vibration damper includes two half-shells formed together about the torsion bar. Damper elements are disposed between the half-shells. The damper elements can be adjusted via an adjustment component to alter the rigidity of the damper elements.
Claims13
A roll stabilizer for a motor vehicle, comprising:
- a torsion bar comprising two torsion bar parts;
- an actuator disposed between the torsion bar parts for transferring a torque;
- a vibration damper for reducing vibrations of the roll stabilizer, the vibration damper comprising two half-shell components that form an annular clamp configured to vibrate with respect to the torsion bar;
- and
- a damper spring disposed between the torsion bar and the vibration damper;
- and
- the vibration damper includes at least one adjusting screw configured for adjusting a rigidity of the damper spring to a selected one of a plurality of different rigidities;
- and
- an upper retaining clamp and at least one lower retaining bracket configured to enable orienting the vibration damper in any rotational direction with respect to a longitudinal axis of the torsion bar.
A vibration damper for reducing vibrations of a roll stabilizer for a motor vehicle, comprising:
- an upper retaining clamp and one or more lower retaining brackets for attaching to a torsion bar comprising the roll stabilizer;
- a first damper element arranged on a first longitudinal edge of the upper retaining clamp;
- a second damper element, separated from the first damper element, arranged on a second longitudinal edge of the upper retaining clamp;
- an annular clamp for clamping the first damper element and the second damper element;
- and
- a first adjustment component for varying a rigidity of the first damper element and a second adjustment component for varying a rigidity of the second damper element.
A method for reducing an undesired vibration of a roll stabilizer for a motor vehicle, comprising:
- fastening, via a first plurality of fasteners, an upper retaining clamp and one or more lower retaining brackets to a torsion bar comprising the roll stabilizer;
- fastening two half-shell components of an annular clamp onto damper elements via a second plurality of fasteners such that:
- i) the upper retaining clamp extends through the annular clamp, ii) the second plurality of fasteners extend through the damper elements without extending through the upper retaining clamp, and, iii) the first plurality of fasteners are arranged outside of the annular clamp;
- and
- adjusting the damper elements to a frequency of an undesired vibration via the second plurality of fasteners.
