Patent ID: 8863370

Claim:
A method for producing a windshield wiper apparatus for a motor vehicle, with a wiper motor and with at least one wiper bearing in which a wiper shaft is mounted, the wiper shaft being driven by means of the wiper motor in order to actuate a wiper arm connected to the wiper shaft, wherein the wiper bearing has a bearing pin ( 4 ) for receiving a tubular support, which bearing pin is fixed on the tubular support by means of crimping, characterized in that, for the production of a stress-optimized connection between the tubular support and the bearing pin ( 4 ), the method comprises the following steps: crimping a first tubular support with one or more crimping tools, without the bearing pin ( 4 ) being disposed in the tubular support; determining an inner contour ( 3 ) of the first tubular support, the inner contour arising as a result of the crimping; calculating a stress-optimized outer contour ( 5 ) of the bearing pin ( 4 ) on the basis of the inner contour ( 3 ) of the first tubular support after the crimping of the first tubular support; producing the bearing pin ( 4 ) in such a manner that, even before a second tubular support is pushed onto the bearing pin ( 4 ), said bearing pin has the outer contour ( 5 ) which is formed, at least in a region in which the bearing pin will overlap with crimping of the second tubular support, so as to correspond to the inner contour ( 3 ) of the first tubular support after the crimping of the first tubular support; pushing the second tubular support onto the bearing pin ( 4 ); and crimping the second tubular support onto the bearing pin with the same one or more crimping tools used to crimp the first tubular support.
