Patent number: 6287007
Abstract: The invention is based on a wiper bearing with a bearing housing (10, 12, 14, 16, 18, 20, 22, 124), in which a drive shaft (24, 26, 28) is supported with a radial bearing (30, 32, 34) and is guided on the end face by way of a stop ring (36, 106) and a crank plate (38, 40), which are connected to the drive shaft (24, 26, 28) and directly or indirectly constitute axial bearings (42, 44, 46, 48, 50, 52, 54, 56, 58, 60) with the bearing housing, wherein a seal (62, 64, 66, 68, 70, 72, 74, 76, 78, 80) rests in a sealed fashion against the bearing housing (10, 12, 14, 16, 18, 20, 22, 124) and against a part (36, 106, 38, 40) connected to the drive shaft (24, 26, 28). The proposal is made that the seal (62, 64, 66, 68, 70, 72, 74, 76, 78, 80) be disposed with a radial distance from the radial bearing (30, 32, 34) outside the axial bearing (42, 44, 46, 48, 50, 52, 54, 56, 58, 60) and seal the bearing gaps of the axial and radial bearings (42, 44, 46, 54, 56, 58, 60; 30, 32, 34) in relation to the outside.
