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 and connected in a concentric manner in relation thereto, the inner tube (24) extending through the bearing housing (12) and for mounting a bearing shaft, 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 a free space is formed between the journal (30) and an inner circumference of the annular element (16).

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

4. 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) through a side wall of the bearing area (14).

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

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

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

8. Wiper bearing according to claim 6, characterized in that the journal (30) is arranged off-center with respect to an axial extension of the bearing housing (12).

9. 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).

10. 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).

11. Wiper bearing according to claim 10, characterized in that the journal (30) is fastened to the inner tube (24).

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

13. Wiper bearing according to claim 12, characterized in that the journal (30) has a cross section embodied as a hollow profile.

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

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

16. Wiper bearing according to claim 1, characterized in that the journal (30) has a cross section embodied as a double T-support including a first T-support portion and a second inverted T-support portion.

17. 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.

18. Wiper bearing according to claim 1, characterized in that the inner tube (24) protrudes from the bearing housing (12).

19. Wiper bearing according to claim 1, characterized in that the journal (30) is connected at one end to the bearing housing (12) and has an opposite end, in that the annular element (16) is fastened with braces (18, 20) to the bearing housing (12), in that free space is provided between the journal (30) and the annular element (16) and between the journal (30) and the braces (18, 20) substantially from the one end of the journal (30) to the opposite end of the journal (30), and in that a tubular plate (40) is insertable into the free space to extend along the journal (30) from the opposite end and proximate the bearing housing (12).

20. 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), that a free space is formed between the journal (30) and an inner circumference of the annular element (16), and 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).
