Abstract

The invention relates to a half shell for a torsion bar bearing (10, 10A), comprising: a half-shell body (1, 1A, 1B, 1C, 1D, 1E) formed in one piece and along a body axis (A); and at least one stiffening device (8, 8A, 8B, 8C, 8D, 8E) adapted to increase a rigidity of the half-shell body (1, 1A, 1B, 1C, 1D, 1E). The invention relates further to a torsion bar bearing (10, 10A) comprising: at least one first half shell and at least one second half shell, wherein at least one of the at least one half shell is disposed opposite to at least one of the at least one second half shell with respect to a torsion bar axis, and to a method of supporting a torsion bar.

First claim

What is claimed is:

1. A half shell for a torsion bar bearing, comprising:
a half-shell body formed in one piece and along a body axis; and
at least one stiffening device adapted to increase a rigidity of the half-shell body,
wherein the half shell comprises a jacket means, which encloses the half-shell body and the at least one stiffening device substantially completely, and
wherein the jacket means is formed of an elastomer.

2. The half shell according to claim 1 , wherein the at least one stiffening device comprises at least one inner rib element,
wherein the at least one inner rib element is disposed on an inner surface of the half-shell body.

3. The half shell according to claim 2 , wherein the at least one inner rib element:
is formed integrally or in one piece with the half-shell body; or
is adapted to be mounted on the half-shell body or on the inner surface.

4. The half shell according to claim 1 , wherein the at least one stiffening device comprises at least one outer rib element,
wherein the at least one outer rib element is disposed on an outer surface of the half-shell body.

5. The half shell according to claim 4 , wherein the at least one outer rib element:
is formed integrally or in one piece with the half-shell body; or
is adapted to be mounted on the half-shell body or on the outer surface.

6. The half shell according to claim 1 , wherein the at least one stiffening device comprises at least one internal rib element,
wherein the at least one internal rib element is disposed in the half-shell body.

7. The half shell according to claim 6 , wherein the at least one internal rib element is enclosed by the half-shell body and/or is formed integrally or in one piece with the half-shell body.

8. The half shell according to claim 1 , wherein the at least one stiffening device is formed by at least one recess or bore in the half-shell body,
wherein the at least one recess or bore is disposed between an inner surface of the half-shell body and an outer surface of the half-shell body and/or along the outer surface and/or along the inner surface.

9. The half shell according to claim 8 , wherein the at least one recess or bore is open toward the outer surface and partially extends through the half-shell body in the direction of the inner surface; and/or
wherein the at least one recess or bore is open toward the inner surface and partially extends through the half-shell body in the direction of the outer surface; and/or
wherein the at least one recess or bore is open toward the outer surface and the inner surface and extends completely through the half-shell body.

10. The half shell according to claim 1 , wherein the half-shell body is formed of a metal and/or a plastic and/or a composite material.

11. The half shell according to claim 1 , wherein the half shell further comprises a fastening device, which is adapted to secure the half shell to a corresponding half shell, and optionally,
wherein the fastening device has at least one latching element and/or at least one screw element and/or at least one pressing element.

12. A torsion bar bearing comprising:
at least one first half shell which is the half shell according to claim 1 ; and
at least one second half shell which is the half shell according to claim 1 ,
wherein at least one of the at least one first half shell is arranged opposite to at least one of the at least one second half shell with respect to a torsion bar axis.

13. The torsion bar bearing according to claim 12 , wherein the torsion bar bearing comprises at least one frame device configured to:
hold or fix at least one of the at least one first half shell and at least one of the at least one second half shell relative to one another; and/or
hold or fix at least two of the at least one first half shell relative to one another; and/or
hold or fix at least two of the at least one second half shell relative to one another.

14. A method for supporting a torsion bar, comprising:
providing a torsion bar;
providing at least one first half shell which is the half shell according to claim 1 ;
providing at least one second half shell which is the half shell according to claim 1 ;
disposing one of the at least one first half shell on the torsion bar; and
disposing one of the at least one second half shell opposite to the one of the at least one first half shell with respect to a torsion bar axis.
