Definitions
- the invention relates to a wiper bearing according to the type of the main claim.
- Known wiper bearings of this type have a shaft which is seated in a bearing fixed to the frame and which transmits an oscillating movement generated by an electromotive drive via a crank drive to a wiper arm and thus to a wiper blade resting on a disc. Since the windshields often have considerably different radii of curvature within the pendulum area of the wiper, particularly in newer motor vehicles, the alignment of the wiper blade to the surface of the window, which should be as perpendicular to the window as possible to ensure a towing movement, is not always optimally achievable. It has therefore already been proposed to align the axis of the wiper shaft at a certain angle relative to the surface of the window. A vertical alignment of the wiper blade is thus achieved at least for a central area. However, the alignment of the wiper blade over the entire wiping area remains unsatisfactory.
- the wiper bearing with the features of the main claim has the advantage that the alignment of the wiper blade to the window surface is made possible over a much larger area of the wiper field. For example, it is possible to set optimal conditions in both reversal positions or in one reversal position and one park position or in an area near the reversal positions by appropriate alignment of the first or second axis.
- Wiper shaft with the second axis at an angle there is a further possibility for optimization.
- FIG. 1 shows a first exemplary embodiment schematically
- FIG. 2 shows part of the shaft according to FIG. 1 in a variant, shown enlarged
- FIG. 3 shows a second
- FIG. 4 shows a third exemplary embodiment.
- FIG. 1 shows a wiper system 10 which has an electric motor 12 with a gear 14 which transmits a pendulum movement to a shaft 22 via two crank gears 18 and 20 connected by means of a crank rod 16.
- the shaft 22 is accommodated in a region 24 by a bearing shell 26 which is fixed to the frame and protrudes from the bearing shell 26 with an area 32 having a receptacle 28 for a wiper arm 30.
- the two regions 24 and 32 have first and second axes 34 and 36, respectively, which form an angle ⁇ with respect to one another.
- the axis 34 runs through the bearing shell 26 fixed to the frame and is thus also fixed to the frame.
- the axis 36 performs a wobbling movement on a conical surface during the wiping operation.
- the two areas 24 and 32 of the shaft 22 have a kink in the transition area.
- FIG. 2 shows a variant of the shaft 22, the region 32 of which here has a curved course starting from the region 24 surrounded by the bearing shell 26.
- the receptacle 28 for the wiper arm 30 has a third axis 38 which forms an angle ⁇ with the axis 36.
- the axis 36 also executes a wobbling movement running on a conical jacket.
- the region 32 of the shaft 22 can also have a cranked profile 39, the cranking of which then merges into the receptacle 28.
- FIG. 3 shows a second exemplary embodiment, in which, in contrast to the exemplary embodiment according to FIG. 1, the crank mechanism 20 is not arranged on the side of the shaft 22 opposite the receptacle 28.
- a crank arm 40 engages at the transition of the areas 24 and 32, so that the frame-fixed mounting of the shaft 22 below and the area of the shaft carrying out the pendulum movement are arranged above the crank arm 40. In this way, the crank mechanism can be guided directly under the hood, which may be advantageous for a low-profile wiper system.
- the third exemplary embodiment shown in FIG. 4 is similar to the second exemplary embodiment, the area 24 of the shaft 22 reaching almost up to the receptacle 28 here.
- the second axis 36 coincides with the third axis 38 here. This results in a smaller wobble movement imposed on the wiper arm 30.
