Definitions

  • the present invention relates to a windscreen wiper device for a motor vehicle with a wiper motor, which is fastened via a gear housing connected to the wiper motor to a wiper carrier formed on a vehicle body of the motor vehicle by means of a motor board by the wiper carrier between the motor board and the transmission housing is clamped.
  • a gear housing connected to the wiper motor to a wiper carrier formed on a vehicle body of the motor vehicle by means of a motor board by the wiper carrier between the motor board and the transmission housing is clamped.
  • Windscreen wiper devices of the above type are already known. It is basically the goal to connect the wiper motor as safe as possible to the vehicle body and to be able to absorb bending and torsional loads. At the same time, the windshield wiper device should enable cost-effective production.
  • a fastening device for a windshield wiper device in which the attachment of the wiper carrier takes place between a motor board and a shell construction encompassing the wiper carrier.
  • this type of fastening presents itself as very complicated and error-prone due to the contours of shell and wiper carrier to be adapted precisely.
  • the manufacture of the shell construction is very costly. The occurrence of tolerances in the production is a major problem with this type of attachment.
  • a windshield wiper device which comprises a wiper motor, which has a connected to the wiper motor gear housing and a motor board with a Wiper carrier is attached in the form of a particular designed as a hollow profile clamping tube to the vehicle body.
  • the transmission housing has a plurality of screw sockets, which are arranged at a distance to a driven-side mounting dome.
  • the wiper carrier is inserted between the screw neck on the one hand and the fastening domes on the other hand or pressed into it, so that the wiper carrier can be supported on the fastening dome and on the screw neck.
  • a holding device in the form of a motor board is provided above the wiper carrier, which is screwed on the screw with the gearbox and is supported according to the screw neck and the mounting dome or the anvil of the gear housing.
  • the wiper carrier is clamped between the gear housing and the motor board.
  • this object is achieved in that at least one projection is provided on the motor board and / or the gear housing, which is arranged such that it bears against the wiper carrier to form a positive connection.
  • a positive connection between the wiper carrier and the projection is additionally realized.
  • the lead acts as a kind of gearing, which becomes one counteracts any bending and / or torsional force by appropriate support on the wiper carrier.
  • much higher axial forces and bending or torsional moments can be absorbed at the connection of the windshield wiper device.
  • the size of the windscreen wiper device or the connection of the windscreen wiper device remains unchanged.
  • the projection may be integrally formed with the transmission housing and / or the motor board in an embodiment of the present invention. This is particularly advantageous in that the variety of parts, in particular during assembly and thus also the risk of assembly errors is reduced.
  • a particularly simple and reliable embodiment of the present invention provides to carry out the projection as a punch-bending tab.
  • the stamped and bent pocket can be designed such that it forms as large a contact surface as possible with the wiper support. This can be achieved, for example, in that an end face of the punched and bent tab is contoured to form the wiper carrier, in particular its contact area with the end face of the punched and bent tab.
  • the projection can also be introduced by simple embossing in the motor board. If a projection is to be provided on the transmission housing, advantageously the projection can already be formed during the casting of the transmission housing.
  • the projection may also be formed as a separate component and screwed to the motor board and / or the gear housing, welded, soldered or glued.
  • This makes it possible to provide appropriate anti-rotation also in already manufactured motor boards or gear housings and / or to make the position of the projections variable. Furthermore, this ensures that, for example, in the event of failure of the material of the projection latter can be exchanged in a very simple manner.
  • the material of the projection can be selected to be elastic, in particular resilient, in order to further increase a coefficient of friction between the projection and the wiper carrier.
  • Figure 1 is a schematic partial view of a windshield wiper device according to the invention in section;
  • Figure 2 a motor board with two projections according to the invention in plan view
  • Figure 3 the motor board according to Figure 2 in a side view
  • FIG 4 a partial view of a windshield wiper device according to the invention according to Figure 1 with mounted wiper carrier.
  • FIG. 1 shows a partial representation of a windshield wiper device 1 according to the invention. For simplicity, the presentation has been reduced to the attachment principle.
  • the windshield wiper device 1 has a wiper motor, not shown, which is fastened via a gear housing 2 connected to the wiper motor and an engine board 3 to a vehicle body of the motor vehicle.
  • a wiper carrier 4 is provided here in the form of a clamping tube on the vehicle body, which is clamped between the gear housing 2 and the motor board 3.
  • the wiper carrier 4 is formed as a hollow profile and inserted into the transmission housing 2, that it is passed between a mounting dome 5, in which an output shaft 6 is mounted, and two Befest Whilesdomen 7.
  • the connection of the windshield wiper device 1 to the vehicle body is achieved in this embodiment by a clamp connection, by mounting the motor board 3 on trained on the transmission housing 2 Be festungsdome 7 screws 8 are inserted through formed in the motor board 3 openings 9 and bolted to the Befestriensdomen 7.
  • the fastening domes 7 are arranged offset in the axial direction of the wiper support 4 on both sides of the mounting dome 5 of the output shaft 6.
  • the peripheral surfaces of the mounting dome 5, 7 are tapered to compensate for any manufacturing tolerances of the wiper support 4 can.
  • a plurality of projections 10 are provided in the form of stamped and bent tabs in the motor board 3, which form a kind of toothing of the motor board 3 with the wiper carrier 4.
  • the projections 10 have a substantially triangular cross-sectional area, from which a line-shaped contact surface with the wiper carrier 4 is set in the mounted state.
  • the outer contours of the projection 10 are first cut out of the motor board 3 by cutting or punching and the cut or punched projections 10 then bent down in the direction of the wiper support 4 until a contact between the projections 10 and adjusts the wiper carrier 4.
  • the end faces 1 1 of the projections then form a positive connection with the wiper carrier 4 and, to a certain extent, catch on the wiper carrier 4 so as to secure it against twisting or slipping.
  • the end faces 1 1 are formed so that they extend substantially parallel to a central axis formed by the wiper carrier 4.
  • the projections rotated exactly 90 ° to the projections shown 1 1.
  • the end faces can also be formed contour following.
  • the end faces may be formed such that they have a recess with a curve corresponding to the radius of the wiper carrier.
