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.

First claim

The invention claimed is:

1. A roll stabilizer for a vehicle, comprising:
a torsion bar; and
a vibration damper located on the torsion bar, the vibration damper configured to vibrate relative to the torsion bar, the vibration damper including:
first and second half-shell components forming an annular clamp about the torsion bar, wherein the first half-shell component ends in first planar end surfaces, and the second half-shell component ends in second planar end surfaces,
first and second damper elements, each located between and directly contacting one of the first planar end surfaces and one of the second planar end surfaces, and
an adjustment component configured to adjust a rigidity of the damper elements.

2. The roll stabilizer of claim 1 , wherein the first and second damper elements are made of an elastomer.

3. The roll stabilizer of claim 1 , wherein the adjustment component includes a screw configured to, when tightened, decrease a distance between the first and second half-shell components and alter a rigidity of the damper elements.

4. The roll stabilizer of claim 1 , further comprising a retaining clamp between the first and second half-shell components.

5. The roll stabilizer of claim 4 , wherein the first and second damper elements are attached to the retaining clamp via an adhesive or via vulcanization.

6. A vibration damper comprising:
first and second half-shell components, wherein the first half-shell component ends in first planar end surfaces, and the second half-shell component ends in second planar end surfaces each facing respective first planar end surfaces,
first and second damper elements, each located between and directly contacting one of the first planar end surfaces and the respective second planar end surface,
an adjustment component configured to adjust a rigidity of the damper elements; and
a retaining clamp between the first and second half-shell components, wherein the first and second damper elements are attached to the retaining clamp via an adhesive or via vulcanization.

7. The vibration damper of claim 6 , wherein the first and second damper elements are made of an elastomer.

8. The vibration damper of claim 6 , wherein the adjustment component includes at least one screw configured to, when tightened, decrease a distance between the first and second half-shell components thereby altering a rigidity of the damper elements.

9. A roll stabilizer for a motor vehicle, comprising:
a torsion bar;
a vibration damper having a damper element configured to vibrate in relation to the torsion bar, wherein the damper element includes first and second of half-shell components collectively forming an annular clamp, wherein a first planar end surface for the first half-shell component faces a second planar end surface of the second half-shell component; and
a damper spring functionally disposed between the torsion bar and the damper element, wherein the damper spring is located and clamped directly between the first and second planar end surfaces;
wherein the damper spring is made of an elastomer component which is retained at a first side on the roll stabilizer, and on a second side on the damper element; and
further wherein the elastomer component is plate-shaped and is attached at a longitudinal edge to a retention device, and is clamped between the half-shell components on both sides thereof, wherein there is an exposed spring section of the plate-shaped elastomer component disposed between the longitudinal edge and the clamping section.

10. A roll stabilizer according to claim 9 , further comprising:
the retention device having a retaining clamp to which the longitudinal edge of the elastomer component is attached with adhesive or through vulcanization.
