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.
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 drivable 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 (1), said bearing pin being fixable to the tubular support (1) by means of a crimp, characterized in that the bearing pin (4) has an outer contour (5) which, even before the crimp is introduced, is 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).
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 (1), which bearing pin is fixed on the tubular support (1) by means of crimping, characterized in that, for the production of a stress-optimized connection between the tubular support (1) and the bearing pin (4), the method comprises the following steps:
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 (1), which bearing pin is fixed on the tubular support (1) by means of crimping, the method comprising:
