Definitions

  • the invention relates to a motor vehicle according to the preamble of claim 1.
  • the windshield wipers In motor vehicles, the windshield wipers have so far been arranged individually, usually in pairs on the windshield, for example, they are coupled by a linkage.
  • the wiper system usually also includes containers for the washing liquid and the associated spray nozzles and pumps. All of these elements are currently individually assembled and distributed across the engine compartment. This requires an inappropriately complex assembly work and is also associated with unsatisfactory accessibility of the individual elements. While, for example, modular assemblies have been proposed for vehicle doors and vehicle cockpits (DE 197 09 835 AI, DE 197 53 178 AI), which are completely on their outside of the vehicle before they are installed proper function can be checked, an integrated overall solution has not been known for windshield wiper systems.
  • the invention is therefore based on the object
  • Motor vehicle with a windshield wiper arrangement containing at least one electric drive motor for at least one wiper arm, a transmission between the drive motor and at least one wiper arm axis, and any coupling elements for the coordinated movement of a plurality of wiper arms, which enables simplified assembly and functional testing of the windshield wiper arrangement.
  • the drive motor, the gearbox, the wiper arm axis (s) and their bearings as well as the coupling elements are combined on a common mounting plate to form a module unit which can be installed as a whole and is independently wired and provided with an electrical connection and which is thus inserted into a body cutout That this is covered by the mounting plate results in a ready-to-install, testable assembly that is easy to install and easy to use.
  • Body section through the mounting plate gives the advantageous possibility of including the module unit in the statics of the body and / or assigning additional functions to the module unit that are otherwise performed by the body.
  • the water supply (rainwater or windshield washer fluid) below the windshield are at least partially taken over by the mounting plate of the module unit. It is advantageous here if the mounting plate has a circumferential seal that reliably prevents moisture from penetrating into the body.
  • the module unit must be checked for its proper function during the preliminary test, but especially during transport and optimally protected during assembly.
  • the cover it is possible to design the cover so that it strengthens the mounting plate and thus supports its function in the statics of the body.
  • a module unit, the mounting plate has a circumferential seal and the components are encapsulated as described above, can be designed so that it can be mounted with attached wiper arms from the outside of the body, for example in that the mounting plate has a protrusion all around the cover. This simplifies assembly and significantly shortens it, since the wiper arms can then be precisely positioned beforehand.
  • a toothed belt transmission can be provided to achieve a coordinated wiper arm movement.
  • the toothed belt as a coordinating element of the wiper arm movement has the advantage that it is mainly in the reversal points of the
  • toothed belt Another advantage of the toothed belt is that it can be deflected so that it can be accommodated in the cover of the module unit even if the drive path between the wiper arms is curved.
  • the known coupling of the wiper arms by a push rod is also possible.
  • the module unit has a plurality of electrically and / or electronically synchronizable drive motors for the movement of a plurality of wiper arms, since in this case the number of mechanical components of the module unit, but above all the number of mechanical wear parts, is minimized.
  • the degree of integration of the module unit can be expanded without difficulty: nozzles for the windshield washer fluid with the corresponding supply lines, possibly also heaters for the washer fluid and / or the spray nozzles, as well as containers for the washer fluid including the electrical level control and the required pumps. Since the module unit can be included in the statics of the body, it is possible to extend it over almost the entire area of the lower edge of the window. In terms of space requirements, it is then possible to implement all the components belonging to a windshield wiper and washer system in a module unit with shorter cable routes and a minimized number of components with an optimized installation option, which can be delivered pre-tested.
  • the windshield wiper arrangement can be used particularly advantageously in vehicles whose cockpit is designed in accordance with DE 197 53 178 AI, since in these vehicles a box profile runs below the front window edge, in which there is sufficient space for accommodating all components of the windshield wiper arrangement.
  • the mounting plate is then part of the box profile, whereby it also takes over the water flow under the edge of the pane.
