Definitions
- the present invention relates to a windshield wiper device, in particular for a rear window wiper of a motor vehicle, with a wiper motor which drives a wiper lever via a transmission arrangement housed in a transmission housing, wherein the transmission arrangement for transmitting a rotary movement of the wiper motor in an oscillating rotational movement Output shaft has a gear which is mounted in the transmission housing via a plurality of bearings.
- the transmission housing is easier and less expensive to produce and more flexibly settable.
- bearings are formed in a bearing plate, which is inserted or used in the transmission housing and fixed or fixable therein.
- the gear housing can also have a same basic structure for different types of transmission.
- the bearing plate can be adjusted for different external dimensions by individually introducing the bearings to different gear types to be used become.
- the injection molding tools for the gear housing are much easier to produce and it is also due to the possibility to achieve the inner workings of the gear housing by changing the bearing plate, only a single injection mold for the production of the gear housing necessary, which also has a respect to the prior art much simplified construction Has.
- the bearing plate can be inserted into the transmission so that at least one wall portion of the transmission housing forms a stop surface for positioning and / or fixing of the bearing plate in the transmission housing.
- a reduction in the variety of parts is achieved in that it is no longer necessary to provide positioning lugs for the insertion of the bearing plate in the gear housing.
- a force applied to the bearing plate by the gear during operation of the wiper motor applied force on the stop surface of the wall portion of the gear housing, which strongly counteracts damage to the bearings on the bearing plate due to the possibility of power dissipation.
- At least one positioning lug may be provided in the gear housing for positioning the bearing plate.
- a particularly accurate positioning can be achieved by the bearing plate is formed konturtechnischd to the side inner walls of the transmission housing.
- Contouring according to the invention means that the outer boundaries of the bearing plate substantially coincide with the inner contour of the transmission housing. This can be realized very easily, for example, by fixing the bearing plate in the transmission housing by insert molding.
- the bearing pins replacing the bearing bolts in the gear housing can be formed, for example, by a plurality of bearing pins introduced into the bearing plate.
- bearing pins are introduced by deep drawing in the bearing plate.
- a recess is provided in the bearing plate into which a sintered bearing for supporting the output shaft can be inserted.
- a sintered bearing for supporting the output shaft can be inserted.
- the rigidity of the sheet so that they can absorb the forces occurring. This can be achieved for example by a metal sheet with a sufficient wall thickness and a suitable material.
- the transmission is a transfer gear which comprises a push rod and a web connected to the push rod, which holds a one-piece formed with him toothed segment equidistant from the rotatably connected to the output shaft pinion, with which meshes the toothed segment, and a via the wiper motor driven worm wheel, wherein the worm wheel and the toothed segment are each received in the gear housing via a bearing pin formed in the bearing pin.
- a method is proposed according to the invention with the following method steps: punching of the bearing plate with the introduction of a recess for a bearing point of the output shaft;
- a recess is provided in the bearing plate into which a cylinder bearing for the output shaft can be pressed to then insert the output shaft in the bearing of the bearing plate.
- the cylinder bearing may for example be a sintered bearing.
- FIG. 1 and 2 is a partial perspective view of a windshield wiper device according to the prior art
- Figure 3 is a plan view of a bearing plate according to the invention with two bearing seats; and FIG. 4 shows a sectional view along the section line A - A of the bearing plate according to FIG. 2
- FIGS. 1 and 2 show a partial perspective view of a windshield wiper device 1 for a rear window wiper of a motor vehicle according to the prior art.
- the windshield wiper device 1 has a wiper motor 2, which drives an output shaft 4 via a gearbox accommodated in a transmission housing 3, via which a wiper lever, not shown, can be moved back and forth on a Wndtikus of the motor vehicle.
- the gear arrangement has a transfer gearbox 5 in the exemplary embodiment shown.
- the transfer gear 5 has a push rod 6 and a via a bearing pin 7 hingedly connected to the push rod 6 toothed segment 8.
- the toothed segment 8 is spaced apart from the axis of rotation of the output shaft 4 via a detachable bearing pin 9 fixed in the gear housing 3 rotatably mounted and connected via the push rod 6 hinged to a worm wheel 10.
- the toothed segment 8 meshes with the rotatably mounted on the output shaft 4 pinion.
- the bearing plate 12 is made in the present embodiment of sheet steel and has a thickness of the corresponding material thickness to achieve a rigidity of the bearing plate 12, which is sufficient to ensure a very accurate position of the bearings formed in the bearing plate 12 bearing 13 to each other, especially under load ,
- the bearing plate 12 has rounded wall sections in its corner regions and is contoured corresponding to the lateral inner walls of the transmission housing 3. This contour-following and accurate fit shape of the bearing plate 12 can be perfected by the bearing plate 12 is encapsulated after manufacture to form the transmission housing 3.
- two bearing points 13 are introduced by deep drawing in the present embodiment.
- the bearing plate 12 has a recess 14 into which a cylinder bearing, in particular a sintered bearing for supporting the output shaft 4 can be inserted.
- the bearing plate 12 is thus initially punched out with the introduction of a recess 14 for a bearing point for the output shaft 4. Subsequently, a plurality of bearing pins 13 are introduced by means of deep drawing in the bearing plate 12 to receive the gear, in this case the worm wheel 10 and the toothed segment 8 of the transfer gear in the transmission housing. Subsequently, the bearing plate 12 is encapsulated to form the transmission housing 3 and the components of the transfer gear 5 are inserted into the transmission housing 3. Thereafter, a cylinder bearing for the output shaft 4 is inserted into the space provided for recess 14 in the bearing plate 12 and finally the output shaft 4 is inserted through the recess 14 in the cylinder bearing.
