Windshield wiper apparatus

摘要

The invention relates to a windscreen wiper apparatus for a motor vehicle, having a wiper motor and having at least one wiper bearing in which a wiper shaft is mounted, it being possible to drive said wiper shaft by means of the wiper motor in order to operate a wiper arm which is connected to the wiper shaft, wherein the wiper bearing has a bearing pin (4) for holding a tubular support (1), it being possible for said bearing pin to be fixed to the tubular support (1) by means of a crimp, characterized in that the bearing pin (4) has an outer contour (5) which is already formed, at least in a region of overlap with the crimp, so as to correspond to an inner contour (3) of the crimped tubular support (1), before the crimp is introduced, and also to a method for producing said windscreen wiper apparatus.

1. 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.
