Definitions
- the invention relates to a wiper system and a drive unit for a wiper system for a windshield of a vehicle, in particular a motor vehicle with two windshield wipers driven simultaneously. More specifically, the invention relates to a specific arrangement of the elements of a vehicle window wiper system.
- Wiper systems for vehicle windows are known to have a drive motor which drives the wiper blades of the windshield wipers via their respective swivel radius via a linkage which is connected to wiper bearings of windshield wipers.
- a drive motor which drives the wiper blades of the windshield wipers via their respective swivel radius via a linkage which is connected to wiper bearings of windshield wipers.
- Such a known construction of conventional wiper systems is shown in a top view in FIG.
- the wiper system has a motor 4 which is fastened to a holding plate 15 which is connected to a drive rod 3.
- the wiper shafts 7, 8 are connected to the holding plate 15 via a connecting tube 19.
- the drive torque of the motor 4 is transmitted to the wiper shafts 7, 8 at the wiper bearings 5, 6 via joints and deflectors.
- the driver-side wiper bearing 5 is connected to the linkage 3, for example via a deflector 14, the deflector or the deflecting member 14 protruding laterally outwards by an amount X in the parking position of the driver-side windshield wiper.
- a disadvantage of this conventional arrangement of a wiper system is that the wiper bearings 5, 6 have to be arranged in such a way that there is an area laterally in the direction m outside in which deflector or deflection crank 14 can deflect in both directions. This prevents optimal use of the wiping surface, since an unwiped area inevitably remains in the area near the A-pillars.
- the largest possible wiping area should be able to be cleaned over a given vehicle window.
- a wiper system for a windshield of a vehicle in particular a motor vehicle, is provided with a drive rod between an engine and a wiper bearing of a wiper shaft, the motor and the linkage being arranged and designed such that a drive crank of the wiper shaft is provided at least on the driver side may be that it is oriented in any position in a direction towards the center of the vehicle.
- the bearing point of at least the driver's side can thus be located further outside than before.
- the feasible wiping area is increased.
- the motor is arranged in the direction of travel of the vehicle in front of and at a distance from the wiper bearing, the drive rod having at least one crank or lever for driving the wiper shaft which is oriented in any position (swivel position) in a direction towards the center of the vehicle.
- the wiper bearing can be arranged closer to the respective vehicle pillar and in particular to the A pillar of the vehicle than before. In this way it is possible to achieve a substantially parallel end position for the wiper from the edge region of the window of a vehicle. As a result, dead areas in which an unwiped or dirty area is left after wiping with the windshield wipers of the vehicle are avoided.
- the motor of the wiper system is connected to a driver-side wiper bearing via the drive rod.
- the wiper bearings of the windshield wiper system of the vehicle has to be connected to a linkage aligned in the longitudinal direction of the vehicle, that is to say essentially in the direction of travel Y of the vehicle. The space requirement is thus reduced to a minimum.
- At least the driver-side wiper bearing is arranged in the vicinity of an A-pillar of the vehicle.
- the area of a vehicle window that is particularly critical for the driver's view is thus completely cleaned and wiped as far as possible.
- the wiper bearing of the at least one windshield wiper is arranged in such a way that an essentially parallel alignment of the windshield wiper to the respective A pillar of the vehicle is reached in an upper wiper end position. This ensures that the remaining edge area, in which wiping does not occur, is reduced as much as possible.
- a wiper shaft on the passenger side is driven via a gear rod which is connected to a driver's crank.
- the drive rod thus has only a single rod, which extends in the direction of travel, and thus requires less space than if both wiper shafts were driven in the direction of travel via respective drive rods.
- two wiper shafts are driven directly by the motor via respective linkages.
- the required drive power of the engine and the direct claim of the respective wipers is cheaper here.
- a mounted deflector or gear disk is provided, via which the wiper bearing is driven indirectly.
- the relative arrangement of the wiper motor and the linkage is therefore more variable. A space-optimized arrangement and design of the wiper system is made possible.
- the motor of the wiper system is arranged approximately in the middle between a driver-side wiper bearing and a passenger-side wiper bearing.
- the introduction of force into the wiper shafts via respective rod parts is better than if an arrangement of the wiper motor that is essentially parallel in the direction of travel is selected to one or the other wiper bearing.
- Figure 1 shows a wiper system according to the prior art in a plan view.
- Fig. 2 is a schematic plan view of a driver's side
- Wiper area of a wiper system according to the prior art and according to the invention in comparison;
- FIG. 3 shows a schematic top view of a first exemplary embodiment of a wiper system according to the invention
- FIG. 4a shows a schematic top view of a second exemplary embodiment of a wiper system according to the invention
- FIG. 4b shows a detailed view of a part of the transmission linkage of the exemplary embodiment from FIG. 4a in a sectional side view;
- FIG. 5 shows a plan view of a third exemplary embodiment of a wiper system according to the invention.
- Fig. 6 is a partial plan view of a fourth exemplary embodiment of a wiper system according to the invention.
- FIG. 1 shows how an arrangement of elements of a wiper system has previously been solved in the prior art:
- a motor 4 is essentially located between two wiper bearings 5, 6, which it has via a drive rod 3 and deflector 14 for generating the reversing wiping movement of (Not shown) operated wipers.
- the two Wiper bearings 5, 6 are rigidly spaced apart from one another via a connecting frame 19. Due to this arrangement of the motor 4 and the drive linkage 3 essentially between the two wiper shafts 7, 8, it is necessary in both synchronous and counter-rotating systems that deflectors 14 are provided which protrude outwards at least on the driver's side.
- deflectors 14 are provided which protrude outwards at least on the driver's side.
- a deflector 14 projects laterally outwards from the wiper shaft 7 or the bearing 5 by an amount X in the park position of the wiper system. In conventional vehicles, it is therefore not possible to implement an approximately parallel arrangement of the wiper blade with the respective A-pillar.
- FIG. 3 A first exemplary embodiment of a wiper system according to the invention is shown schematically in FIG. 3.
- the wiper motor 4 is arranged in the direction of travel Y of the vehicle in front of the two wiper shafts 7, 8 and is connected to the latter via an additional gear crank 13 and a gear disk 16.
- the driver's crank 9, which is connected to the wiper shaft 7 and carries out a back and forth movement during operation of the wiper system, can thereby be aligned in the direction of the center of the vehicle, that is to say a direction which points to the other wiper shaft 8.
- the wiper shaft 7 can be arranged very close to the (not shown) A-pillar of the vehicle, since a swivel space on the right side of the wiper shaft 7 (outside) is not required. This allows a larger area of the vehicle window to be wiped (see area 12 in FIG. 2).
- a second exemplary embodiment of a wiper system is shown schematically in a top view in FIG. 4a and in detail in FIG. 4b.
- each wiper shaft 7, 8 is driven here directly by means of a gear rod 3 via a gear disk 16 and not only the driver-side wiper shaft 7.
- the gear disk 16 which is fastened to the motor 4 and driven by it, has a Eccentric disc 17 connected.
- the eccentric disc 17 has a smaller diameter than the gear disc 16.
- the diameter can also be the same; it is crucial that the wipers are in the extended position and in the parking position at the same time.
- the motor 4 is arranged in the direction of travel Y in front of the two wiper shafts 7, 8, so that in particular the driver's crank 9 only protrudes inwards in each swivel position, so that an additional area near the A pillar of the vehicle can be wiped in a synchronous wiper system.
- FIG. 5 shows a further exemplary embodiment according to the invention in a simplified top view.
- the motor 4 is indeed arranged between the two wiper shafts 7, 8, but the arrangement is also selected here via a gear washer 16 and a deflection mechanism 18 and an intermediate rod 21 such that the driver-side and passenger-side crank 9, 10 each in protrude inwards in every swivel position.
- This drive system also enables a closer arrangement of the wiper shafts 7, 8 on the respective A-pillars, specifically here with a synchronous as well as with one Up-wiper system.
- FIG. 6 shows a fourth exemplary embodiment of a wiper system according to the invention.
- both wiper bearings are driven by a separate motor 4 (only one side is shown).
- a gear disk 16 drives the crank 9 on the wiper bearing 7 via deflection bearings and a drive rod 3.
- the counter torque is received by a holding tube 20 between the bearing 7 and the motor 4.
- a corresponding drive unit is provided for the second wiper bearing (not shown).
- This embodiment is equally suitable for counter-rotating as well as synchronous wiper systems.
- the invention can be applied to different wiper systems, e.g. Systems that have a single, two or even more than two wipers.
- the wiper systems can be operated in opposite directions or in the same direction.
