Abstract

A method for fixing a cover on an orifice of a power steering system including a step of approaching the cover to the orifice, characterized in that it includes a step of inserting at least one extension of the cover in at least one recess positioned next to the orifice and a step of deforming the at least one elongation of the cover.

First claim

The invention claimed is:

1. A method for fixing a cover on an orifice of a power steering system comprising:
a step of approaching the cover to the orifice;
a step of inserting at least one extension of the cover in at least one recess positioned next to the orifice; and
a step of deforming the at least one extension of the cover, wherein
the deformation step further includes an at least partial melting phase of the at least one extension of the cover.

2. The method according to claim 1 , wherein the deformation step further includes a positioning phase in which an anvil is placed in contact with an edge of a protective wall of the cover facing a first end of the at least one extension and a deforming element is placed in contact with a second end of the at least one extension.

3. The method according to claim 1 , wherein the deformation step further includes a bending phase of the at least one extension, the bending phase being carried out before the insertion step.

4. A cover configured to be fixed to an orifice of a power steering system by implementing the method according to claim 1 , the cover comprising:
a protective wall at least partially surrounded by an edge, the at least one extension being irreversibly connected to the edge.

5. The cover according to claim 4 , wherein the at least one extension extends along an orthogonal axis to a plane along which the protective wall extends.

6. The cover according to claim 4 , wherein the cover is made of a material from: poly(butylene terephthalate), or polypropylene.

7. The cover according to claim 4 , wherein the at least one extension has a length greater than a length of the at least one recess into which the at least one extension is configured to be inserted.

8. The cover according to claim 4 , wherein the at least one extension includes two elements extending parallel to one another.

9. The cover according to claim 4 , wherein one end of the at least one extension includes a protrusion.

10. The cover according to claim 4 , wherein the at least one extension includes at least two legs connected to a free end of a rod.
