The invention relates to a wiper bearing, comprising a bearing housing (10, 12, 14, 16, 18, 20, 22, 124) in which a drive shaft (24, 26, 28) is mounted with a radial bearing (30, 32, 34), the front end of said drive shaft being guided by a thrust ring (36, 106) and a crank plate (38, 40) which are solidly connected to the drive shaft (24, 26) and which together with the bearing housing, form directly or indirectly axial bearings (42, 44, 46, 48, 50, 52, 54, 56, 58, 60). A seal (62, 64, 66, 68, 70, 72, 74, 76, 78, 80) rests tightly against the bearing housing (10, 12, 14, 16, 18, 20, 22, 124) and a part (36, 106, 38, 40) which is solidly connected to the drive shaft (24, 26, 28). According to the invention, the seal (62, 64, 66, 68, 70, 72, 74, 76, 78, 80) is situated outside the axial bearing (42, 44, 46, 48, 50, 52, 54, 56, 58, 60) at a radial distance from the radial bearing (30, 32, 34), and outwardly seals the bearing gap between the axial and radial bearing (42, 44, 46, 54, 56, 58, 60; 30, 32, 34). |
