Abstract

A bearing for mounting an anti-roll bar on a bogie frame, the anti-roll bar extending along an axis transverse to the bogie and being mobile in rotation relatively to the frame around the axis, the bearing including a first half-shell, and a second half-shell adapted so as to be attached on the first half-shell by means of a first attachment system, the first half-shell and the second half-shell then forming a housing crossing through along the axis and adapted for receiving the anti-roll bar. The first half-shell is distinct from the frame and adapted so as to be attached on the frame by means of a second attachment system.

First claim

The invention claimed is:

1. A bearing for mounting an anti-roll bar on a frame of a bogie, the anti-roll bar extending along a transverse axis of the bogie and being mobile in rotation relatively to the frame around the axis, the bearing comprising:
a first half-shell mechanically secured to the frame, and
a second half-shell attached on the first half-shell using an attachment system,
wherein the first half-shell and the second half-shell form a housing crossing through along the axis and receiving the anti-roll bar,
wherein the first half-shell being distinct from the frame and attached on the frame using the attachment system, and
wherein the attachment system is formed by attachment screws crossing the first half-shell and the second half-shell, said attachment screws being screwed into the frame.

2. The bearing according to claim 1 , wherein the first half-shell and the second half-shell are structurally analogue with each other.

3. The bearing according to claim 1 , wherein the first half-shell and the second half-shell are symmetrically positioned relatively to a middle plane of the bearing, the middle plane passing through the axis.

4. The bearing according to claim 1 , wherein each of the first half-shell and the second half-shell comprises:
a central portion forming a hemicylindrical cradle, and
two attachment tabs located on either side of the central portion along a direction substantially perpendicular to the axis, each attachment tab including at least one pierced hole provided for the attachment system.

5. The bearing according to claim 4 , wherein the attachment tabs of the first half-shell respectively include two supporting faces intended to respectively press on the two protrusions of the frame.

6. The bearing according to claim 4 , wherein the attachment system is formed with two pairs of attachment screws, the pairs of attachment screws being respectively attached in the attachment tabs.

7. A bogie comprising:
a frame,
at least two bearings according to claim 1 , and
at least one anti-roll bar received in the housings formed by both bearings.

8. The bogie according to claim 7 , wherein the frame includes at least four protrusions, each of the first half-shells being attached on two of the protrusions.
