Definitions
- the invention relates to a windshield wiper system drive attached to a carrier tube according to the preamble of claim 1.
- Windscreen wiper systems are known. Particularly in vehicles, windscreen wiper system drives are fastened to a carrier tube in the front part of the vehicle, in particular an engine compartment.
- the attachment must fix the windshield wiper system drive in a predetermined, necessary for the operation of the windshield wiper system area and this particular case of significant forces by arranged on the windshield wiper system drive windscreen wiper or their arranged to effect the wiping movement rods safely.
- windshield wiper drives should be easy to assemble and disassemble in order to avoid unnecessary labor costs in the event of maintenance.
- a fastening device for this purpose, which effect such a fastening via clamping devices, which are designed in a different way as the support tube encompassing half-shell construction, and via shape-fitting passports, especially noses.
- a disadvantage of these and other solutions known from the prior art is that the connections are effected by means of elements which are difficult to produce and which require a relatively exact adaptation of the shape.
- Such shell geometries, such as those formed on additional half-shells or gear housings of a windshield wiper system drive are expensive to manufacture and thus relatively expensive.
- Other solutions work with flat, closed profile cross-sections, are screwed through the connecting screws in the windshield wiper system drive. At these low bending resistance is disadvantageous. Disclosure of the invention

- the generally round cross-section of the support tube which is used to achieve the highest possible bending load capacity of the pipe cross-section, is therefore formed in the carrier support to a flat surface, for example by attaching a flattening of the round cross section.
- the formation of the plane surface is effected, which rests flat on the Rheinrohrabstützung. Consequently, here are two flat surfaces, namely the Suguabstützung and the flat surface, in contact with each other.
- no shape adaptation in particular no shell geometry, is required for embracing the round tube cross section.
- the at least one fastening screw passes through the support tube, for example, by holes or punched holes or other suitable recesses mounted in the support tube, and clamps the support tube between its screw head and the carrier tube support. Due to the design of the flat surface, the rests flat on the support support, this already a very good fixation between the support tube and Ausstrahlabstützung is achieved. In particular, this ensures that the carrier tube support can not roll radially around the lateral surface of the support tube, in particular under load, as occurs during operation of the windscreen wiper system. The force is introduced namely via a positive connection between the carrier pipe support and the plane surface.
- the Rushrohrabstützung here is of course also designed as a flat, flat surface.
- Flat surface / flattening of the support tube opposite pipe wall surface also plan, in particular flattened, is formed.
- the fastening screw can be even easier and with a larger bearing surface for the screw head bring, whereby a better initiation of clamping forces.
- the diameter of the carrier tube is formed at least in the region of the carrier tube support as a rectangular cross-section.
- a rectangular or cross-section is understood to mean, in particular, a square or approximately square cross-section, for example one whose formation the circumference of the support tube is flattened substantially equally on four opposite sides so that, viewed in cross-section, at least approximately a square is formed. In such an embodiment, significantly higher clamping forces can be transmitted via the fastening screw.
- the support tube has in the region of the support support tube planar side walls, wherein the fastening screw has a screw head and / or a Unterleg medium, which projects into the region of the side walls of the support tube.
- the fferenzugkraftiques runs in such an embodiment parallel to the side walls or, more preferably, at least in / on a side wall direction.
- the clamping force of the fastening screw is therefore introduced via its screw head or a washer arranged between the screw head and support tube, in particular a washer, substantially directly into the side walls of the support tube, which can accommodate a significantly higher screw tensile force due to their running in the direction of screw tensile force walls, as a wall or a wall section that could not be in synchronenzugkraftraum runs, but at least partially transversely or approximately transversely thereto.
- the risk of deformation of the support tube by applying a high screw tensile force is substantially less or almost impossible in the proposed embodiment. In any case, can be effected in this way synchronenzug element that allow a very secure releasable attachment of the windshield wiper system drive to the support tube without the risk of deformation of the support tube is.
- Carrier tube support has at least one cooperating with at least one side wall support wall. At least one support wall is thus formed on the support tube support, which cooperates with at least one side wall of the support tube. In this way, a multi-sided, namely at least two-sided, fixation of support tube and
- Windscreen wiper system effect so that in this way a very good introduction of force line and rotation of the windscreen wiper system drive is effected relative to the support tube.
- the support wall is formed substantially transversely to the Sudrohrabstützung, thus occupies the carrier tube support at an approximately right angle.
- Complicated holding devices in particular for the attachment of shell screw joints, as known from the prior art, are not required here.
- the windscreen wiper system drive has a transmission with a transmission housing.
- About the transmission can cause over and / or reduction of the windshield wiper system drive.
- the gear housing is therefore at least an integral part of the fastening device, in particular by forming the Schwarzrohrabstützung on a portion of the transmission housing.
- FIG. 1 shows a section of a carrier tube with a plane surface
- Figure 2 is a cross-sectional view of a fastening device
- Figure 3 is an exemplary illustration of a transmission housing with a
- Carrier support and support walls are Carrier support and support walls.
- FIG. 1 shows a carrier tube 1, which has a substantially square cross section in a carrier tube section 2, which is formed from flattenings 3 of a round cross section in the remainder of the carrier tube 1, and where the essentially square cross section of the carrier tube 1 is essentially parallel opposite, planar side walls 4 is formed. Transition regions 6, which effect the transition from the round cross-section to the square cross-section, are located between circular cross-sectional areas 5 and the carrier tube section 2 arranged between them.
- the square cross section can be obtained in particular by slabs of the otherwise round cross section, for example by pressing and / or cold deformation of the support tube 1.
- the support tube section has on a flat side wall 4, namely a top 7 and on one of these opposite, not visible here due to the bottom, recesses 8, for example, holes 9 or punched, each serving to introduce a fastening screw, not shown here, wherein the fixing screw on one of these levels Side walls 4, for example, the top 7, supported by a screw head.
