1. A wiper drive (100) for a rear window wiper of a motor vehicle (105), comprising:
a drive unit (110) having a wiper shaft (125) for pivoting in an oscillating manner about an axis of rotation (130); a protective cap (135) which surrounds the wiper shaft (125) over an axial portion; wherein the protective cap (135) is connected by means of a radial press connection to a housing (115) of the drive unit (110),characterized in that
the protective cap (135) comprises a latching element (140) which engages in a cutout (145) in the housing (115) in order to absorb axial forces on the protective cap (135), wherein the latching element (140) has a hook portion (320) with an axial (345) and a radial (350) bearing surface in each case for bearing against a corresponding bearing surface (510, 505) in a region of the cutout (145) of the housing (115), and an angle between the axial (345) and the radial (350) bearing surface of the hook portion (320) is less than 90°, wherein a plurality of latching elements (140) are provided at different radial angles on the protective cap (135), each of the latching elements (140) including a hook portion (320), wherein the housing (115) includes a plurality of cutouts (145) to receive segments of the hook portions (320), wherein each of the hook portions (320) includes an axial (345) and a radial (350) bearing surface in each case for bearing against a corresponding bearing surface (505, 510) in a region of one of the cutouts (145) of the housing (115), and an angle between the axial (345) and the radial (350) bearing surface of each of the hook portions (320) is less than 90°, wherein the housing (115) includes an outer boundary surface (505) that is a portion of a cylinder, and wherein the radial bearing surfaces (350) are also each a portion of a cylinder and extend parallel to the axis of rotation. |
