Definitions
- Wiper system for a means of transportation in particular a motor vehicle
- the invention relates to a Wscherstrom for a means of transportation, in particular a motor vehicle, preferably a small vehicle, with at least one W shear component.
- Wiper systems are known from the prior art, in which the two wiper bearings of the Wscherstrom are fixed to one another via a support tube.
- a carrier tube is usually crimped by a crimping process to a mounting pin of a housing of the wiper bearing.
- a wiper motor is clamped to this support tube.
- Wscheranlagen are known in which the wiper motor is screwed to one of the Wscherlager.
- the carrier tube serves to position the exchanger bearings or their wiper shafts in a correct position - distance and angle relative to one another. The entire Wscherstrom can then be screwed at Anschraubddlingen on the housings of the shuttle bearing to a vehicle body.
- the crimping between the carrier tube and the mounting journal of the wiper bearing requires close tolerances to ensure proper mechanical connection later. Ie.
- the tight tolerances of the necessary crimping in the mounting pin make the crimp connection comparatively expensive
- the crimp notches require relatively large dimensions of the mounting pin and thus also the support tube at least in its connecting portion with the mounting pin to a mechanically stable enough Wi to receive shear equipment.
- the crimping grooves weaken the mounting pin, since they must be provided deep inside the mounting pin.
- the Wscherstrom should be simple and inexpensive to produce, paying particular attention to a simple assembly of the components of the Wscherstrom. This is preferably on high investment for a machine such. As a crimping machine can be dispensed with.
- the wiper system should be easily mountable in the means of transport and a mechanical connection between two components of the Wscherstrom should be simple in this case.
- the scrubber system according to the invention has at least two wiper components, the scrubber components being fixed to one another via a plate-shaped element, in particular a metal or steel sheet.
- the at least two wiper components are preferably two wiper bearings, a wiper bearing and a wiper motor, or two wiper bearings and a wiper motor, wherein preferably a respective housing of the wiper component is connected to the plate-shaped element.
- other components preferably in any combination with those just mentioned, may be provided on the plate-shaped element.
- This relates in particular to a push rod bearing device and / or another bearing device.
- the plate-shaped element is designed such that it can be mounted on / in the means of locomotion.
- the inventive solution is particularly suitable for so-called LCLs (Low Cost Location), as can be dispensed with an expensive and expensive crimping process.
- LCLs Low Cost Location
- crimping machine eliminates the difficult to control crimping, for which in the manufacturing expertise and thus skilled personnel is needed.
- the tolerances of the entire Wscherstrom in particular the connection features for a user of the wiper system, such as mounting points and orientation of the Wscherachsen in space, according to the invention essentially only a dimensional accuracy of the plate-shaped element, the z. B. may be formed as a sheet metal plate depending. Many due to a manufacturing tolerances, which z. B. by the crimping process or items, such as the carrier tube are eliminated.
- the compliance with dimensional tolerances, in particular the compliance with small tolerances are easier to achieve or with a more elementary skill.
- identical wiper bearings on the driver and passenger side, or use of identical storage wagons in different projects - can be achieved by a resulting increase in the number of units a cost advantage.
- the plate-shaped element of the laundry installation has at least one fastening device and / or at least one fastening device by means of which the plate-shaped element can be mounted on / in the means of locomotion.
- the relevant fastening device or the relevant fastening device may be a fastening element, a fastening point or a fastening section of the plate-shaped element.
- a through hole, a fastening tab or a fastening projection is used.
- the relevant fastening device or the relevant fastening device may have a decoupling element, in particular a decoupling rubber.

- a project-specific adaptation of the plate-shaped element with a raised edge and stiffening beads the strength and rigidity of the wiper system compared to a solution with support tube can even be increased.
- a weight-optimized design can be realized.
- the relevant wiper component and the plate-shaped element can be fixed to one another in a positive, positive and / or material fit.
- the relevant blender component is preferably screwed or riveted to the plate-shaped element, or the relevant wiper component is preferably provided by means of a method for clinching on / in the plate-shaped element. But also a locking, a pressing, a jamming, a soldering, a welding are applicable.
