Description

Technical area

The present invention relates to a windshield wiper assembly for motor vehicles with at least one movably mounted wiper arm, on which at least two flexible wiper lips are provided, which slide on commissioning of the wiper assembly on the outside of a vehicle window.

background

There are different designs and concepts for motor vehicle windshield wipers. Common windscreen wiper assemblies have at least one wiper arm, which slides either in a pendulum or in a translational sliding movement along, for example, a rear or front window of a motor vehicle.

In order to eliminate dirt that accumulates or accumulates on the disc, it is further provided to spray a washing or cleaning fluid onto the disc and to clean the disc wetted with the washing fluid with the aid of the windscreen wiper.

For example, describes the DE 197 30 099 A1 a wiper blade with a wiper edge having a wiper area and a holding area, wherein parallel to and on either side of a wiping edge at least one more wiping edge is arranged to form a respective channel for a rinsing liquid. This windshield wiper blade is further provided with a tilting function, which causes the wiping direction corresponding tilting of the wiper edges in a forward and backward movement of the wiper, so seen in the wiping direction of the wiper arm, always two spaced in the wiping direction and mutually parallel wiping edges with the disc to be cleaned are in contact.

Although a quite satisfactory wiping result can already be achieved with such an arrangement, the use of a plurality of mutually parallel wiper lips proves to be disadvantageous. Since in such double lip wipers always two wiper lips are in contact with the disc, there is a higher static friction and sliding friction for the wiper blade on the disc surface. Accordingly, the windshield wiper drive to apply a larger drive torque. Furthermore, an increased contact pressure of the windscreen wiper is to be provided on the disk to be cleaned.

Also, individual windshield wiper components must be designed according to the increased mechanical load requirements and accordingly more stable, usually larger and heavier. Furthermore, common double-lip wiper arrangements have the disadvantage that when a cleaning procedure is carried out in the dry state, the wash water sprayed via a channel extending between the wiper lips is picked up only by the wiper lip lying behind in the direction of movement, whereas the leading wiper lip is comparatively dry on the window along slides. This leads to a relatively high wear of the wiper lips and shortens their life.

The present invention is based on the object to provide a Wiper lip wear and durability improved windshield wiper assembly, which further provides good wiper results under weight reduction and reduced material usage. Further, the windshield wiper assembly is compared to a double lip wiper require a lower contact pressure on the disc and a lower drive torque of the windshield wiper drive.

Preferred embodiments

This object is achieved with a windshield wiper assembly according to claim 1 and with a motor vehicle according to claim 14, wherein advantageous embodiments are each the subject of dependent claims.

The intended windshield wiper arrangement is designed for cleaning a windshield of a motor vehicle and has at least one movably mounted wiper arm, on which two wiper lips aligned substantially parallel to one another are pivotably mounted about a wiper lip axis extending substantially parallel to the wiper lip longitudinal direction. The wiper lip axis runs parallel to the position of the wiper lips. It is preferably arranged symmetrically to the wiper lips. The wiping edge of the wiping lips facing the pane to be cleaned together with the wiper lip axis advantageously forms an isosceles triangle.

Furthermore, a pivoting mechanism is provided by means of which the wiper lip, which in each case is positioned downstream of the leading edge of the wiper arm in relation to the direction of movement of the wiper arm, can be transferred to a raised position relative to a washer to be cleaned. That is, the wiping lips spaced apart in the wiping direction on the wiper arm are by means of Pivoting mechanism pivotable such that each lying in the direction of movement rear wiper lip with the disc in the contact position, while the leading wiper lip is transferred to a raised, detached from the disc position.

In this case, it can be achieved that, during operation of the windshield wiper arrangement, only one of the wiper lips is in contact with the windshield in each case. The contact pressure required for the wiper arm for the wiping operation can be reduced to a level that is typically provided for a single-lip wiper. Also, the static and / or sliding friction of the windshield wiper assembly can be reduced to the level of a single lip wiper, which advantageously affects the minimization of the applied by a windshield wiper drive torque.

Furthermore, since only the wiper lip lying behind or in the direction of movement is in contact with the pane to be cleaned, dry running of a leading or wiping lip in front in the direction of movement can be largely avoided, even if a cleaning process of a dry pane is provided by applying cleaning liquid. In that regard, the pivoting mechanism also serves to minimize wiper lip wear and accordingly increase the life of the wiper lips.

According to an advantageous embodiment, it is provided that the wiper lips are fixedly connected to one another on the wiper arm. The wiper lips are thus immovable to each other, but the wiper arm opposite pivotally formed. By the fixed connection of the wiper lips with each other can be achieved that both wiper lips can always be moved together by means of the pivot mechanism on the wiper arm linkage.

The individual wiper lips can also be formed integrally according to a development. In that regard, a single, two to the disc aligned wiper lips having wiper lip body can be provided.

Alternatively, two individual wiper lips are provided, which are fastened to a common, pivotally mounted relative to the wiper arm bracket.

According to a further preferred embodiment, it is further provided that the wiper lips, with respect to the wiper lip axis, are oriented radially outward. That is, the mutually parallel wiper lips may be aligned tilted about their longitudinal axis, so that the wiper lips occupy a predetermined angle to the disc upon reaching a contact position with the disc to be cleaned. The wiper lips can be seen in this respect from their wischarmseitigen connection point, be aligned towards the disc diverging to each other.

According to a further preferred embodiment, it is provided that between the at least two wiper lips, a fluid-carrying channel for loading the disc with a washing liquid is arranged. In this case, the channel can have a plurality of outlet openings or spray nozzles for the washing liquid in the longitudinal direction in order, if necessary, to be able to wet the washer to be cleaned with washing liquid along the longitudinal extent of the wiper lips.

By means of the channel extending between the wiper lips washing liquid leading channel can be a well-dosed wetting of the vehicle window with washing liquid. In addition to a washing liquid consumption optimization, a much smaller impairment of the field of view for the vehicle occupants can be provided, since the washing liquid is applied only locally around the wiper arm around the disc and removed directly from the field of view of the vehicle occupants by means of the wiper lip trailing in the direction of movement.

By lifting the wiper lip leading in the wiping direction, dry running can advantageously be avoided in the case of a washing process starting from a dry pane.

According to a further embodiment, the pivot mechanism has a radially spaced from a pivot axis of the wiper arm and fixedly arranged on a vehicle body control plate. On the wiper arm and / or on the side facing away from the vehicle window of the wiper lips a cooperating with the control plate driver is formed. In the course of a pendulum pivotal movement of the wiper arm, the driver comes into contact with the control plate and is guided along this. In this case, the control plate interacts in particular with the rear surface of the driver facing away from the disk surface and presses the wiper arm onto the disk to be cleaned.

In this case, it is provided in particular that the control plate extends substantially parallel to the plane of the pivoting movement of the wiper arm, and that the driver has two mutually opposite run-on slopes, which are designed to initiate a pivoting movement of the wiper lips by a strip along the control plate. The driver is running to Control plate towards pointed or tapered to, wherein the opposite, symmetrically formed to the tip run-on slopes are adapted to the provided for the respective direction of movement of the wiper arm pivot position of the wiper lips.

The extent of the control plate in the wiping direction is chosen such that immediately after a reversal of direction of the wiper arm of the driver abuts with a run-on slopes on the control plate and the run-up slope exerts a tilting moment in the progress of Wischarmbewegung on the wiper arm or on the wiper blades. At the opposite end of the wiper movement get driver and control plate again disengaged. The wiper arm pivots back into a basic position, so that with the onset of the opposite wiping movement, the opposite run-on slope can interact in a similar manner with the control plate.

The control plate is formed in accordance with the wiping movement of the wiper arm. In a rotatably mounted wiper arm, it has a circular segment-like contour. Of course, the windshield wiper assembly can also be implemented as a linear wiper. The control plate would accordingly extend essentially in a straight line and parallel to the wiping direction.

According to a further development, an alternative pivoting mechanism provides two drive elements which are spaced apart from one another in the axial direction and coupled to the pivot axis with respect to the pivot axis of the wiper arm. The axial distance of the drive elements requires that one of the drive elements is close to the disc and the other is arranged at a greater distance from the disc, thus far away from the disc on the pivot axis of the wiper arm. In this case, provision is made in particular for the drive element arranged close to the disk to be able to be driven ahead of the drive element remote from the disk.

The disk-distal drive element performs an anticipatory disk-near drive element identical drive movement, but this offset in time. From the relative movement of disk drive and disk remote drive element arranged a respective wiping direction corresponding pivoting movement to the wiper arm or on the wiper lips are derived.

In accordance with a further development thereof, it is provided that the drive elements are designed as drive disks arranged essentially parallel to one another, wherein the drive disk arranged away from the disk has a link guide extending in the circumferential direction of the disk. In this one arranged with the disc near the drive pulley connected coupling element is guided.

In this case, it is provided in particular that only the drive disk arranged close to the disk is directly coupled to a windshield wiper drive. About the coupling element and provided on the disc-distal drive pulley guide slot can be achieved that the disc-distal drive pulley is delayed in a direction reversal of the disc near the drive pulley delayed in motion.

Instead of a slotted guide of a coupling element can be further provided according to a development that the drive elements are coupled via a bearing guided in a bush bearing, wherein a drive element is coupled with two circumferentially spaced from bearing or bushing stop elements, between which one with the other Drive element coupled counter-stop element is guided.

Thus, for example, be provided that the bearing connected to the disc near drive element bearing has a radially outwardly projecting stopper or driver pin, which is adapted to take with reaching a stop position on a radially inwardly projecting counter-stop of the bearing bush, the disc-distant drive element, which with the bearing bush is connected. Equally, of course, this reverse arrangements of stop and counter-stop elements in the range of nested bush and bearing are conceivable.

According to a further embodiment, it is further provided for the drive elements or drive disks that the wiper arm or the wiper lips are arranged so as to be pivotable radially to the pivot axis of the wiper arm and are connected to the disk-distant drive element at a distance from the disk drive unit located substantially parallel to the pivot axis.

The connection of the disc-near and disc-distant drive elements is in this case preferably via a handlebar or a comparable connecting rod, which provided the vehicle window facing end portion with the two wiper lips or is coupled thereto. The relative movement of the drive elements provided at the reversal point of the wiping movement causes a tilting of this connecting link, so that in each case one wiper lip rests on the disk, while the other is lifted off the latter.

All of the pivoting mechanisms described above are implemented purely mechanically and provide for the pivotal movement of the wiper arm or the wiper lips about the wiper lip axis to be derived from the rotary or sliding movement of the wiper arm. The described pivoting mechanisms are in this case synchronized with the respective wiping directions. That is, in a direction change of the wiper arm, the wiper lips are pivoted in the manner already described about the wiper lip axis.

In a deviating from this embodiment is further provided that the pivot mechanism has at least one electromechanical actuator, by means of which the wiper arm and / or its wiper blades with respect to the wiper lip axis are pivotable. The use of a preferably arranged on the wiper arm actuator may prove to be advantageous in particular for reasons of space. In that regard, no mechanical coupling means for the pivotal movement of the wiper arm and for the oscillating movement of the wiper lips are provided.

According to a development of an electromechanical implementation is further provided to provide the drive with an electric stepper motor and a control unit which pivot with a change of the wiping movement of the wiper arm, the wiper arm and / or the wiper lips by a predetermined angle. The control unit can be arranged directly in or on the Wischarmgestänge stepper motor. But it can also be integrated directly into the on-board electronics of the motor vehicle. The latter, in particular, if a direction-reversing electric motor should be provided anyway for the windshield wiper drive.

In this case, information about a reversal of direction of the windshield wiper would be present anyway in the on-board electronics, so that no separate sensors would have to be implemented for detecting the reversal point of the wiper arm.

Detailed description

In 1 is a cross-sectional view through a wiper arm 28 a windshield wiper assembly 10 shown. On the wiper arm 28 , whose Wischarmgestänge the 1 does not explicitly show, is a two wiper lips 12 . 14 having double wiper lip 16 attached. The wiper lips 12 . 14 are integrally formed and are about a double-T-like design wiper lip body 16 connected with each other. The wiper lip body 16 At the same time provides a fastening mechanism. Such is the double-T-like structure 16 between two mounting rails 18 . 20 of the wiper arm 28 fixable.

The mounting rails 18 . 20 are in particular designed as spring rails. Further, the wiper arm 28 in the area of his wiper lips 12 . 14 with a spoiler element 24 provided by means of which the wiper arm 28 when an instance occurs Wind wind caused by wind wind can be pressed onto a disk to be cleaned.

Between the wiper lips 12 . 14 is a fluid-carrying channel 22 provided, the channel in the longitudinal direction of individual outlet openings for the washing liquid to be applied to the disc 23 having.

The wiper lips 12 . 14 are formed largely identical and extend from top to bottom, so from their one disc 26 remote connection 18 . 20 down, to the disc 26 out, slightly divergent from each other.

In the 2a and 2 B is the wiper arm 28 according to 1 during an upward movement 30 both in plan view and in cross section along AA shown. It is provided here that the wiper arm 28 but at least his two wiping lips 12 . 14 together around a wiper lip axis 42 pivot as soon as a movement reversal of the wiper arm 28 entry. The pivoting movement of the wiper arm 28 or the wiper lips 12 . 14 around the wiper lip axis 42 is in this case such that, based on the respective direction of movement 30 . 32 of the wiper arm 28 , each in the direction of movement 30 . 32 rear wiper lip 14 . 12 with the underlying disc 26 in contact position occurs while the other, anticipatory wiper lip 12 . 14 goes into a raised position and thus out of contact with the disc 26 arrives.

At a reversal of direction, hence a downward movement 32 as they are in the 3a and 3b is shown, there is a reverse configuration. Here comes the wiper lip 14 in contact with the disc 26 while the wiper lip 12 out of contact with the disc 26 occurs. Again, this is based on the wiping direction 32 upstream wiper lip 12 out of contact with the disc 26 while the lagging or moving direction 32 rear wiper lip 14 exclusively with the disc 26 is in contact.

Such a pivoting mechanism is advantageous to the extent that when cleaning a per se dry disc 26 the only one with the disc 26 in contact position passing wiper lip 12 . 14 always one with washing liquid 23 wetted surface portion of the disc 26 sweeps. Dry running of the windshield wiper, in particular its wiping in the forward direction wiping lips 12 . 14 This can be effectively avoided. This leads advantageously to a reduction in wear and to an extension of the life of the wiper lips 12 . 14 in comparison to a non-oscillating double wiper lip or wiper arm suspension.

In the 4 to 7 is a first, purely mechanical implementation of a swivel mechanism 36 shown. The wiper arm 28 with its wiper lips arranged thereon 12 . 14 is here at a Wischlippenachse extending in Wischarmlängsrichtung 42 stored, which are perpendicular to the actual axis of rotation 34 of the wiper arm 28 extends. Radially spaced from the axis of rotation 34 but outside the area of the wiper lips 12 . 14 is at the vehicle window 26 opposite rear side of the wiper arm 28 a driver 40 arranged, that of the disc 26 turned away with two opposite chamfers or inclined surfaces 44 . 46 tapered or tapered.

Furthermore, the side of the in 4 wiper arm shown in the basic position 28 one on the direction of movement 30 . 32 of the wiper arm 28 adapted control plate 38 provided, which also, based on the axis of rotation 34 axially spaced from the disc 26 is trained. During operation of the wiper arm 28 this drives with the driver 40 in the of control panel 38 and disc 26 formed intermediate space. This learns rotatably on the axis 42 suspended wiper arm 28 a tilting movement, since the according 6 in the direction of movement 30 front inclined surface 44 with the disc 26 facing bottom of the control plate 38 got in contact.

As the wiper arm moves 28 the driver slides 40 in the tilted configuration according to the middle illustration of 6 on the control panel 38 along. In the case of a reversal of motion, consequently in an opposite direction of movement 32 of the wiper arm 28 , as in 7 shown, however, passes the opposite run-on slope 46 in a similar way with the control plate 38 in contact, so the wiper arm 28 or the wiper lips arranged thereon 12 . 14 undergo a correspondingly opposing pivotal movement.

In the 8th to 11 is another, also purely mechanically implemented swivel mechanism 50 shown. In this case, in particular in the region of the pivot axis 34 of the wiper arm 28 two, relative to the wiper arm axis 34 in the axial direction, spaced-apart drive elements 52 . 54 intended. The in 11 the disc to be cleaned 26 facing, thus close to the disc arranged drive element 52 serves as a pivot bearing for the wiper arm 28 or for the wiper lips arranged thereon 12 . 14 ,

The wiper arm is in this case with a connecting rod or a connecting link 76 at a radially outwardly projecting and facing the viewer pin 72 at the wiper arm axis 34 rotatably mounted drive element 52 pivoted. In that regard, the linkage has 76 provided on the disc near drive element 52 a hinge 70 with a recording 74 for the pivot pin 72 on.

The connecting linkage 76 is also about one with a slot 78 provided driver 80 with the disk remote drive element 54 coupled. This has a slot 78 passing through driving pin 82 on.

Due to the long hole guided displacement possibility of the connecting linkage 76 and its pivotal arrangement on the pin 72 of the disc-lying drive element 52 can with a rotation of the drive elements 52 . 54 relative to each other a tilting or pivoting movement on the connecting rod 76 and thus also on the wiper lips 12 . 14 be exercised.

It is even conceivable here, via the connecting rod 76 the two drive elements 52 . 54 to couple together and so far only the disc-arranged drive element 52 to couple with a windshield wiper drive. While the disc drive far to lie coming drive element 54 has such an inertia that at a reversal of the direction of the drive element 52 the drive element 54 only one after completion of a pivoting movement of the wiper lips 12 . 14 a disc-near drive element 52 trailing movement.

In the 8th to 10 are further possibilities for the mechanical coupling of the disc near and far from the disc arranged drive elements 52 . 54 shown. In the illustration according to 8th is a kind of damping bush 55 provided to a common axis 34 rotatably mounted drive pulleys 52 . 54 about a parallel to the axis of rotation 34 extending coupling element 56 to couple with each other mechanically.

The coupling element formed here in the form of a coupling rod 56 is fixed to the drive pulley 52 attached, but on the opposite drive pulley 54 in a backdrop 58 guided. Since also only the disc near the drive pulley arranged 52 is connected to the windshield wiper drive, resulting in a reversal of motion of the drive pulley 52 a time-delayed entrainment movement for the drive disc remote from the disc 54 ,

In this way, in a direction reversal of the wiping movement of the windshield wiper first, a relative movement of the two drive elements 52 . 54 take the pivoting of the wiper arm 28 or his two wiper lips 12 . 14 around the wiper lip axis 42 causes.

The two representations according to 9 and 10 show a further embodiment of a damping bushing 65 , where the two drive disks 52 . 54 are coupled together via the common storage. As the cross-section according to 10 shows is the drive pulley 52 with a warehouse 60 connected, which with one with the upper drive pulley 54 connected bearing bush 62 engaged. Inside on the bearing bush 62 are radially inwardly projecting extensions 44 . 64 provided with a radially outwardly projecting extension 68 of the warehouse can interact.

Only with reaching a mutual stop position of radially outwardly projecting stop pin 68 with one of the radially inwardly projecting counterstops 64 . 66 is, starting from the stock 60 , a torque on the shaft 60 enveloping bushing 62 and thus on the drive pulley 54 transfer.

Regardless of their specific design, the damping bush should 55 . 65 provide a mechanical damping in the direction of movement of the wiper arm which are greater than the contact pressure of the wiper arm 28 on the vehicle window 26 is.

12 finally shows deviating from the 4 to 10 an electromechanical implementation of the pivot mechanism 84 , This is directly on the wiper arm 34 an electric motor 86 with a control unit 88 provided that in a direction reversal of the wiper arm 28 the wiper arm 28 and with him the wiper lips 12 . 14 by a predetermined amount around the wiper lip axis 42 pivoted. If the windshield wiper or wiper arm 28 anyway driven by a counter-driven electric motor, the control unit 88 also outside the wiper arm 28 be integrated into the on-board electronics of the corresponding motor vehicle.

In particular, in a direction reversing electric motor drive for a windshield wiper direction reversal information for the wiper anyway in the on-board electronics of the motor vehicle are present, so that the wischarmseitig arranged, for the pivotal movement of the wiper lips 12 . 14 provided stepper motor 86 directly with a drive not shown here for the pendulum movement of the wiper arm 28 can be coupled.

The illustrated embodiments show only possible embodiment of the invention to which further numerous variants are conceivable and within the scope of the invention. The exemplary The embodiments shown are in no way to be construed as limiting the scope, applicability or configuration possibilities of the invention. The present description merely shows the person skilled in the art a possible implementation of an exemplary embodiment according to the invention. Thus, the most varied modifications can be made to the function and arrangement of elements described without thereby abandoning the scope of protection or its equivalents as defined by the following claims.
