Abstract

The invention relates to a wiper bearing for a windshield wiper system comprising a bearing housing (12) provided with an outer tube forming the bearing housing (12) and an inner tube (24) arranged in a concentric manner in relation thereto and a journal (30) arranged on a bearing area (14) on the bearing housing (12) for receiving a tubular plate (40). It is proposed that an annular element (16), which is arranged in a coaxial manner on the journal (30), be provided outside the journal (30) in the region of the front side thereof (36).

Claims

1. Wiper bearing for a windshield wiper system comprising a bearing housing (12) provided with an outer tube forming the bearing housing (12) and an inner tube (24) arranged in a concentric manner in relation thereto and a journal (30) arranged on a bearing area (14) on the bearing housing (12) for receiving a tubular plate (40), characterized in that an annular element (16), which is arranged in a coaxial manner on the journal (30), is provided outside the journal (30) in the region of the front side thereof (36).

2. Wiper bearing according to claim 1, characterized in that the annular element (16) is arranged connectionless to the journal (30) on the bearing housing (12).

3. Wiper bearing according to claim 1, characterized in that the annular element (16) is fastened with braces (18, 20) on the bearing housing (12), via which the journal (30) is accessible from the outside at least in a connecting area (32).

4. Wiper bearing according to claim 1, characterized in that the annular element (16) is arranged axially in front of the journal (30).

5. Wiper bearing according to claim 4, characterized in that the journal (30) projects with the front side (36) into the annular element (16).

6. Wiper bearing according to claim 1, characterized in that the journal (30) is arranged approximately centric with respect to an axial extension of the bearing housing (12).

7. Wiper bearing according to claim 1, characterized in that the journal (30) is arranged off-center with respect to an axial extension of the bearing housing (12).

8. Wiper bearing according to claim 1, characterized in that the journal (30) is fastened to the inner tube (24).

9. Wiper bearing according to claim 1, characterized in that the journal (30) has a cross section embodied as a hollow profile.

10. Wiper bearing according to claim 1, characterized in that the journal (30) has a cross section embodied as a double T-support.

11. Wiper bearing according to claim 1, characterized in that a component geometry between the annular element (16) and the bearing area (14) can be demolded laterally during its manufacture.

12. Wiper bearing according to claim 2, characterized in that the annular element (16) is fastened with braces (18, 20) on the bearing housing (12), via which the journal (30) is accessible from the outside at least in a connecting area (32).

13. Wiper bearing according to claim 2, characterized in that the annular element (16) is arranged axially in front of the journal (30).

14. Wiper bearing according to claim 5, characterized in that the journal (30) is arranged approximately centric with respect to an axial extension of the bearing housing (12).

15. Wiper bearing according to claim 5, characterized in that the journal (30) is arranged off-center with respect to an axial extension of the bearing housing (12).

16. Wiper bearing according to claim 7, characterized in that the journal (30) is fastened to the inner tube (24).

17. Wiper bearing according to claim 8, characterized in that the journal (30) has a cross section embodied as a hollow profile.

18. Wiper bearing according to claim 9, characterized in that a component geometry between the annular element (16) and the bearing area (14) can be demolded laterally during its manufacture.
