Definitions
- the invention is based on a counter-rotating wiper system according to the preamble of claim 1.
- Wiper systems with several windshield wipers for motor vehicles are attached to their wiper bearings directly or indirectly via a circuit board on a body of the motor vehicle.
- the circuit board carries a wiper drive with a wiper motor, the motor shaft of which drives cranks via a linkage, which are firmly connected to one end of a drive shaft for each wiper.
- the drive shaft is mounted in the wiper bearing, protrudes from the body and moves a wiper arm attached to its free end with a wiper blade over a windshield.
- the wiper arm has a fastening point which is connected in a rotationally fixed manner to the drive shaft and is connected in an articulated manner to a joint part to which a wiper rod is rigidly connected.
- a wiper blade is hooked into the wiper rod at a hook-shaped end.
- the wiper blade generally has a limb-type support bracket system with a main bracket Articulated intermediate brackets, the ends of which are articulated to the claw brackets.
- the claw brackets hold a wiper strip on their ends with their claws.
- the multi-section support bracket system and a spring rail inserted into the head strip of the wiper strip enable the wiper strip to adapt to a curved windshield when wiping with a uniform contact pressure.
- the wiper arm and the wiper blade While driving, when the wiper is not operated, the wiper arm and the wiper blade are in a wind-protected parking position, in a so-called hood gap between an engine hood and the windshield of the motor vehicle. If the windshield wiper is operated, it swivels over the windshield from the wind-protected parking position.
- the wiper blades are arranged one above the other in the parked position in the middle, lower area of the windshield and are moved outward by the drive shafts from the parked position on the windshield to a reversed position and back again, in each case in the opposite pivoting direction.
- actuate a wiper arm via a deflection bearing.
- left-hand drive motor vehicles and right-hand drive motor vehicles it is known to use a counter-rotating wiper system for both versions or to design the counter-rotating wiper system as a whole with mirror symmetry.
- large wiper blades are used, which are arranged one above the other in the park position in the middle area of the windshield.
- the peripheral speed of the wiper increases with the distance from the drive shaft to the free end.
- the lower wiper is usually with its free end closer to the drive shaft of the upper wiper than its drive shaft. If both wipers were operated at the same angular velocity, the lower end wiper, which has a high peripheral speed, would collide with a part of the upper wiper, which is close to the drive shaft and has a low peripheral speed. To avoid this, the lower wiper is moved with a delay from the park position at the start of the wiping movement. So that the windscreen wipers return to their starting position in the park position after the reversal position, i.e.
- the upper wiper comes up again and the lower wiper comes to rest below, the lower wiper is moved to the reverse position and accelerated by the reverse position. Furthermore, the reverse position of the lower wiper is generally farther from the edge of the windshield than the reverse position of the upper wiper.
- the windshield wiper or wiper blade provided for the driver's side is preferably above that for the passenger's side.
- a reverse wiping system designed for a left-hand drive motor vehicle is used in a right-hand drive motor vehicle, the wiping field is smaller on the driver's side in the right-hand drive motor vehicle and the wiping quality is poorer than in the left-hand drive motor vehicle.
- the counter-rotating wiper system in a right-hand drive motor vehicle is designed to be mirror-symmetrical to the counter-rotating wiper system in a right-hand drive motor vehicle, the wiping field on the driver's side is of the same size and the wiping quality is equally good, but the number of components increases almost twice.
- the wiper arm in a left-hand drive version and in a right-hand drive version protrudes further in the wiping direction for the driver side in the parking position than the wiper arm for the passenger side.
- the wiper blade for the driver side lies above the wiper blade for the passenger side and runs in an upward wiping movement and in a downward wiping movement behind the wiper blade for the passenger side.
- the wiper arm for the driver's side in the right-hand drive version is mirror-symmetrical to the wiper arm for the driver's side in the left-hand drive version and the wiper arm for the passenger side in the right-hand drive version.
- the board, the wiper bearings and the drive shafts are the same in both versions.
- the driver can achieve the optimum size and quality of the wiping field and the variety of components, in particular of cost-intensive components, can be reduced.
- the openings for the drive shafts and attachment points for the circuit board of the right-hand drive version and the left-hand drive version can advantageously be arranged at the same points on the motor vehicle body, so that both designs can be mounted in the same openings and at the same attachment points.
- the assembly of the circuit board on the motor vehicle body in the left-hand drive version and in the right-hand drive version is identical and can easily be carried out in an assembly station without the need to change tools. The assembly and production costs of the motor vehicle are reduced and costs are saved.
- the fastening part for the driver's side in the right-hand drive version is particularly advantageous, as is the fastening part 1 for the passenger side in the left-hand drive version, and the fastening part for the passenger side in the right-hand drive version is the same as the fastening part for the
- Driver's side of the left-hand drive version executed.
- the variety of components is reduced and the number of pieces of the same components is increased.
- the fastening point is usually made of aluminum, die-cast zinc or plastic in a die-casting process or injection molding process and is largely solid in its head and cone area.
- the same molds and tools can be used for the right-hand drive version and the left-hand drive version.
- the joint parts are usually stamped and bent parts with a U-shaped profile that is open towards the pane.
- the punching and bending tools can be made adjustable, so that the joint parts with a tool accordingly for the
- Left-hand drive versions and for right-hand drive versions can be adapted and manufactured.
- the joint part for the driver's side in the right-hand drive version is the same as the joint part for the passenger side in the left-hand drive version and the joint part for the passenger side in the right-hand drive version is the same as the joint part for the driver side in the left-hand drive version.
- the wiper arm for the driver's side in the right-hand drive version differs only in the wiper rod to the wiper arm for the passenger side in the left-hand drive version. The same applies to the wiper arm for the passenger side in the right-hand drive version to the wiper arm for the driver side in the left-hand drive version.
- the wiper rod is usually out a solid material made from an adjustable tool that can be used to produce wiper rods for the front passenger side and for the driver side as well as wiper rods for a left-hand drive version and for a right-hand drive version.
- the wiper arms for the right-hand drive version and for the left-hand drive version can be produced with the same tools.
- only the tool for the wiper rod has to be designed to be convertible and to be converted accordingly in the manufacture of the wiper arms. It is also possible to design the joint part and the wiper rod in one piece.
- the fastening part and / or the joint part for the driver side in the same way as the fastening part and / or the joint part for the passenger side in the right-hand drive vehicle design, as a result of which the number of components can be further reduced.
- the different shape of the wiper arms is advantageously achieved solely by the wiper rods, which can be produced inexpensively in an adjustable tool. The same applies to a left-hand drive version.
- a third wiper arm with a wiper blade on the windshield in addition to the wiper arms according to the invention for the driver's side and for the front passenger's side.
- This can, for example, be mounted on a drive shaft mounted in the deflection bearing, whereby additional components can be saved.
