Description

The The invention relates to an adjustment device for level adjustment rope-bound Carrier in a double-stranded Bowden window lifter, with a bowden end piece for adjusting the free rope length, wherein the Bowden end piece a structurally mounted base element and a variable distance adjustable to the base element adjustment comprises, in which a Bowden cover is supported end.

The Invention deals with the problem of level matching the cable-guided driver in a double-stranded Cable window lifter, in particular for a motor vehicle. One Level adjustment becomes necessary after installation of the window regulator Align the windows lying on the driver exactly. The actual level of the driver is determined here by the sum of production- or material-related component tolerances, such as B. the distance of the driver inserted by means of nipple Rope ends, the diameter of the rope pulleys or the distance a Seilumlenkrolle to a Bowden end piece. While are at Today's component design already very low tolerances down to reachable to +/- 3 mm. However, the manufacturer is now Tolerances in the level position of maximum +/- 1.5 mm required. To achieve these low tolerance levels must either the components used are specifically selected or it must be adjustable, the level position of the driver.

An adjusting device with a Bowdenendstück for adjusting the free cable length is for example from the DE 101 51 068 A1 known. There is proposed for a double-stranded Bowden window lifter for adjusting the driver an active Bowden end piece with which the length of a Bowden cover is adjustable. For this purpose, the Bowden end piece has a base element mounted in a manner fixed in terms of structure and an adjustment element which can be variably adjusted in terms of distance to the base element, in which the Bowden cover is supported at its end. To set the driver or to adjust the drivers resting on the window, the Bowden end piece is released from a fixing position, adjusted accordingly and fixed again after the adjustment.

The Indian DE 101 51 068 A1 shown power window comprises a respect to the direction of travel of a motor vehicle front and rear guide rail, on each of which two Seilumlenkrollen are mounted. The cable runs between the respective cable deflection rollers of a guide rail in the adjustment direction of the window pane and in the area between the guide rails in two intersecting cable paths. In the case of the Bowden window lifter, the two crossing cable paths are each guided in a Bowden sheath. The drivers for receiving the window pane are each firmly connected to the cable in the region between the cable deflection rollers of a guide rail and guided along the respective guide rail. By means of the active Bowdenendstücks the length of the Bowden sheath and thus the free rope length is adjusted. Accordingly, the two drivers move in the opposite direction, so that a level adjustment of the two drivers can be done by adjusting the active Bowdenendstücks.

to Adjustment is the window lying on the drivers either in the installed state to the upper stop position in the motor vehicle door or moved into a stop position of an adjustment device and then the Bowdenendstück solved, adjusted accordingly and fixed again.

task The invention is an adjustment of the aforementioned Specify type, which further simplifies level adjustment of the driver allowed to each other.

These Task is solved according to the invention according to a first variant by the feature combination of claim 1. Accordingly, the adjusting element an interface for coupling to an actuator on.

The Invention is based on the consideration, the setting the driver is no longer time consuming by a manual Perform local adjustment but an external Actuator to be used conveniently from a remote control station can be served from. By providing a corresponding Interface on the adjusting element, such an actuator be coupled. Next does not need a suitable tool on site to be held ready for a manual adjustment. moreover Further simplifications can be made to adjust the carrier levels be achieved. In particular, the invention offers the advantageous Possibility by coupling a controllable drive to carry out a process automation. For example, at Measurement of Mitnehmerpegel by means of a corresponding control device the actuator until reaching the desired level adjustment be controlled automatically.

The adjusting element per se can be designed both translationally and rotatably adjustable relative to the base element. Accordingly, a suitable interface for a translatory or for a rotary drive can be provided. For a translational adjustment, the interface in a simple manner, for example, by an exposed attack surface be designed to which a piston of a linear or spindle drive attacks. As an interface for a rotary drive, a gear or a suitably ausgestalteteter polygon offers, which can be rotatably coupled to an output shaft of an actuator. In particular, a gear for rotational adjustment of the adjusting element can be coupled to an output pinion.

The said object is according to another variant solved according to the invention by the feature combination of claim 2. Accordingly, a measuring device for determining the level position of the driver to each other, an actuator to the drive of the adjusting element and one with the actuator and with the measuring device Connected control device provided, wherein the control device is formed, the actuator in dependence on the determined level position automated until the level adjustment of To drive the driver.

The Invention is based on the consideration, the previously to manually adjust on-site adjustment of the drivers. This allows both the process costs and the process times be lowered. Because by adjusting a Bowdenendstücks Both drivers can be affected by the measurement and the adjustment take place simultaneously. The whole automated Setting process can be technically easily realized and done especially fast.

The Bowden end piece for adjusting the length of a Bowden sheath or the free rope length can basically along the cableway at different points of the Bowden window lifter be arranged. In particular, an arrangement in the field offers a motor / gear unit of the Bowden window lifter, in the a guided in a Bowden cable rope opens. Here, the base element is based on the engine / transmission unit from. The adjusting element takes up the end of the Bowden cover. Next, it is possible to have the bowden end between For example, two Bowden sheaths along one of the to arrange crossing cable ways. In this case relies the base element at the end of the one and the adjusting element at the end the other, opposite Bowden cover off.

Prefers However, the base element is on a supporting structure of the Bowden window lifter such as a support plate or the like attached. In a structurally preferred embodiment is the base element mounted on one of the two guide rails. The latter Design variant is particularly suitable for a Bowden window lifter on, in which the guide rails as separate components present, the only at the final assembly on a motor vehicle door be brought into the predetermined position to each other. For one simple plug-in mounting on a support structure of the Bowden window lifter and in particular on a guide rail, the base element a Einsteckkerbe, with which it the corresponding sheet metal part can be plugged.

The Base element does not necessarily have to be designed as a separate component be. Rather, it is also conceivable, the adjusting element with respect to a Support structure of the Bowden window lifter supported directly train. In this case, the support structure is as a base element consider.

The Adjustment element can basically be attached to the base element be guided translationally or stored. In this constructive Design act the male forces directly along the adjustment direction. In this respect, suitable fixatives to a positional fixation of the set Bowdenendstücks provided.

advantageously, is the adjusting element by means of a threaded connection to the base element mounted with variable pitch. In this embodiment, the male act Forces are not in the direction of adjustment, but are from taken up the threaded sections. The threaded connection is particular self-locking in terms of the forces occurring, so that corresponding fixing means for the adjustment can be waived.

in the Case of a rotary adjustment of the adjustment is as Interface for the actuator to be coupled expediently comprises a rotatably connected gear. Such a gear can easily and immediately with a driven pinion of a suitable Electric motor including gear to be coupled.

In In a further preferred embodiment, the adjusting element comprises a rotatably connected polygon to a manual adjustment. Beyond the automated basic setting allows such Polygonal in the case of a repair on the window or when replacing a windowpane a simple manual leveling the Carrier in a workshop. The polygon is for example designed for actuation by means of an open-end wrench.

Preferably, the polygon is also designed for receiving and supporting the Bowden. For this purpose, the polygon is arranged at the end of the adjusting element facing the Bowden sheath and has a correspondingly shaped receiving opening for receiving the Bowden sheath. Due to the expo ned position of the polygon this can easily by means of a suitable tool, such. B. of the mentioned open-end wrench and achieved be operated.

By during operation of the motor vehicle occurring vibrations And it can also be shocking in the case of a self-locking Thread connection between the adjusting element and the base element come to a relative adjustment. To one caused by this Position change of the windows during operation of the motor vehicle is expediently provided an additional anti-rotation. For example the base element is firmly connected to an engagement means which between the teeth of the rotationally fixed with the adjusting element engaged gear engages. The engagement means can in particular be designed in the manner of a ratchet, so that there is an adjustment allows the retention forces, however are large enough to shake up the adjusting element to prevent.

to Carrying out an automated level comparison of the Carrier is advantageously provided a mounting bracket, to a precisely positioned recording of the Bowden window lifter is designed. For example, the mounting device concrete Attachment points on which the Bowden window lifter defined fixed or attached. Due to the exact positioning on a mounting bracket, the relative position of the driver opposite a measuring device that defines a concrete location for mounting bracket or also attached to the mounting bracket. insofar allows the provision of such a mounting bracket another Simplification in the sense of an automated process. Defined specifiable Reference points on the drivers are after fixing the Bowden window lifter always on the mounting bracket to the same desired end position opposite a likewise firmly mounted sensor adjust.

The Providing a mounting bracket offers the further advantage of simple coupling of the actuator. That's the actuator expediently on the mounting bracket such positioned so that when receiving the Bowden window lifter to the Coupling adjusting element. For example, an output pinion egg nes electric motor or the electric motor itself in a predetermined Position firmly mounted to the mounting bracket. By fixing the Bowden window lifter on the mounting bracket or vice versa the fixation The mounting bracket on the Bowden window lifter, for example, couples this Gear of the adjusting element with the pinion to a mutual Combing.

In an alternative embodiment is the actuator to the mounting bracket variably positionable, in particular displaceable or pivotable, arranged. In this variant, the Bowden window lifter first connected to the mounting bracket. Subsequently, the Actuator on the mounting bracket then moved or pivoted, until it is coupled to the adjusting element. In particular, this can a flexible shaft may be provided, for example, with a Polygonal coupling of the adjustment element.

to Measurement of the level position of both drivers can each other different sensors are used. Offer as position sensors in particular optical or acoustic runtime sensors. Next can also mechanical touch sensors be used. Also it is possible the level position to detect the driver by means of capacitive or inductive coupling. In the case of runtime sensors, one may suffice the only sensor that detects the level position of both drivers clocked.

There the drivers of a double-stranded window lifter constructive be designed differently, it is recommended concrete reference points to the drivers to record their level position provided. Via a corresponding calibration of the received Measurement signals can then be easily determined the level adjustment.

embodiments The invention will be explained in more detail with reference to a drawing. Showing:

9 a positioned on a mounting bracket Bowden window lifter according to 1 ,

In 1 is a Bowden window lifter 1 presented for a motor vehicle, as essential supporting structures 2 a first guide rail 3 and a second guide rail 4 having. The guide rails 3 . 4 are each formed as deep-drawn parts made of sheet metal. Along the first and second guide rails 3 . 4 is a first driver 6 or a second driver 7 guided smoothly. The drivers 6 . 7 are not visible in nipple chambers firmly in a revolving rope 9 assembled.

At the first guide rail 3 and the second guide rail 4 are each two Seilumlenkrollen 10 assembled. The rope 9 extends between the respec gene Seilumlenkrollen 10 a guide rail 3 respectively. 4 in adjustment of the driver 6 . 7 and in the area between the guide rails 3 and 4 in intersecting cable ways.

Along the crossing cable ways is the rope 9 each in Bowden covers 12 . 13 and 14 guided. For a structurally strong support of the Bowden sheaths 12 . 13 and 14 are passive bowden tails 15 provided, each against the guide rails 3 . 4 and against a motor / gear unit 16 support. The engine / transmission unit 16 is integrated in one of the crossing cable ways and fixed to the first guide rail 3 assembled. To drive the rope 9 indicates the motor / gear unit 16 a pulley on top of the rope 9 will circulate.

At the bottom of the bowden shell 12 is an active, adjustable Bowden end piece 17 arranged, which is against the second guide rail 4 supported. How out 2 will be seen in a larger section, includes the adjustable Bowden end piece 17 an adjustment 23 on which the bowden sheath 12 end supports, as well as a base element 24 , which is the second guide rail 4 is plugged. The adjusting element 23 is via a threaded connection in the base element 24 rotatable and thus distance variable led to this.

Will the adjusting element 23 operated, thereby changing the length of the Bowden sheath 12 or the free rope length. Due to the crossed cable paths this results in an adjustment of the driver 6 . 7 in opposite directions. If, for example, the adjusting element 23 from the base element 24 turned out, so moves the first driver 6 up and the second driver 7 downward. By actuating a single adjusting element can thus be a level adjustment of the two drivers 6 . 7 done to each other.

For level adjustment of the two drivers 6 . 7 concrete reference points are given to these. By the reference points are the level 21 the first driver and the level 21 ' the second driver 7 given. To record the levels 21 . 21 ' is a measuring device 22 provided by means of suitable position sensors, the position of the defined reference points in the adjustment direction and thus the level position of the two drivers 6 . 7 determined to each other. By checking the measured value of the measuring device 22 can under adjustment of the adjusting element 23 at the bowden end piece 17 the desired level adjustment of the drivers 6 . 7 done to each other.

In 3 is an exploded view in detail the adjustable Bowden end piece 17 according to the 1 and 2 shown. The adjusting element 23 is via a threaded connection 26 with the base element 24 screwed. For this purpose, the adjusting element comprises 23 an externally threaded threaded shaft 27 , The basic element 24 has a shank receiving 28 with a complementary internal thread. In the base element 24 is still a Einsteckkerbe 30 introduced, with which it the sheet metal part of the second guide rail 4 is plugged.

For a rotary drive around the axis of rotation 40 has the adjusting element 23 a polygonal in the form of a hex screw head, whereby a manual operation can be done by means of a conventional ring or wrench. As an interface for coupling to an external actuator is the threaded shaft 27 further rotation with a gear 35 connected. The arranged on the upper shaft end for reasons of accessibility polygon 32 at the same time serves to receive and support the bowden sheath 12 , For this purpose, a correspondingly shaped receiving opening 34 at the top of the polygon 32 intended.

Both the basic element 24 as well as the adjusting element 23 are made in one piece and each made of plastic. It can be seen that in a rotary drive of the adjustment 23 this depending on the direction of rotation in the base element 24 can be screwed in or out, so that the length of the Bowdenendstück 17 supported bowden sheath 12 can be adjusted.

In 4 is opposite 3 modified Bowdenendstück 17 ' shown in assembled state. Here is the adjustment 23 almost completely in the base element 24 screwed. The basic element 24 is integral with an anti-twist device 42 connected. This engages with a nose in the manner of a ratchet between the teeth of the gear 35 one. Thus, the gear can 35 although against the rotation 42 to be turned around. The holding force of the anti-twist device 42 is sufficient, however, to unintentionally twist the Verstel lelements 23 opposite the base element 24 as a result of shock, shock or vibration. Otherwise, the threaded connection 26 between the adjusting element 23 and the base element 24 to a certain extent self-locking. The introduction of with respect to the axis of rotation 40 axial forces does not lead within certain limits to a rotation of the adjusting element 23 ,

In 5 is the bowden tail 17 according to 3 in screwed condition visible. The basic element 24 in this case has no rotation 42 on.

Overall, therefore, is an automatable adjustment 25 to adjust the level of the drivers 6 . 7 created. About the designed as an interface gear 23 An actuator can be coupled, which can be controlled for example from a remote control station for a level adjustment.

In 6 is the Bowden window lifter 1 according to 1 shown, to an exact positioning of a first mounting receptacle 44 is attached. The first assembly shot 44 is designed as a holding plate on which at predetermined positions by means of concrete receiving means such as holes, in particular the second guide rail 4 is attached. From the first assembly 44 In this case, only that section is drawn, the lower part of the second guide rail 4 with the attached adjustable Bowdenendstück 17 receives. The first guide rail 3 is here for the second guide rail 4 exactly aligned, in particular also on the mounting receptacle 44 attached.

On the first assembly shot 44 is as an actuator 46 an electric motor / gearbox block 48 firmly mounted. Due to the defined position this couples when receiving the second guide rail 4 with the gear 35 of the adjusting element 23 to the adjustable Bowden piece 17 at. The coupling is done by approaching the second guide rail 4 like this in the 7 and 8th is shown.

In 7 is in a lateral view the first mounting receptacle 44 shown on the actuator 46 is firmly mounted. The electric motor / gearbox block 48 includes a geared by a mechanical transmission electric motor. About the wave 49 is a pinion 50 driven at a suitable speed. Via a corresponding control circuit, the electric motor used can be controlled both to a right and to a left-hand rotation. The speed can also be specified.

In the in 7 illustrated situation is the second guide rail 4 shown as the first assembly shot 44 is approximated to a fixture. It can be seen that shortly before mounting the pinion 50 of the electric motor / transmission block 48 with the gear 35 of the adjusting element 23 at the bowden end piece 17 in a line perpendicular to the plane of the first mounting receptacle 44 located. In a further approximation of the second guide rail 4 to the first assembly 44 finally couples the pinion 50 to the gear 35 at. The teeth of the pinion 50 and the gear 35 are designed for a meshing engagement.

In 8th is from the same angle as in 7 now illustrated the situation in which the second guide rail 4 at the first assembly reception 44 is attached. By receiving the second guide rail 4 on the first assembly shot 44 Now grab the pinion 50 of the electric motor / transmission block 48 and the gear 35 of the adjusting element 23 at the bowden end piece 17 each other. About a corresponding control of the electric motor, the adjusting element 23 rotationally driven and over the 3 apparent threaded connection 26 in the base element 24 of the bowden tail 17 be screwed in or out. Accordingly, the length of the Bowdenendstück changed 17 supported bowden sheath 12 , As a result, the free rope length of the rope 9 affected. From 1 and 6 apparent driver 6 . 7 are moved in opposite directions, so that a level adjustment between two drivers 6 . 7 is possible. By the coupling of the electric motor / gear block 48 over the trained as an interface gear 35 is by means of the illustrated adjustment device 25 the level adjustment over a remote control station using the measuring device 22 semi-automated or fully automated using a corresponding control device possible.

In 9 is a second assembly shot 51 shown at the for automated leveling the first guide rail 3 and the second guide rail 4 are aligned exactly positioned. In contrast to 6 will now be the drive for the gear 35 on the adjustable bowden end piece 17 provided electric motor / gear block 48 not by mounting the Bowden window lifter 1 on the second assembly shot 51 firmly coupled. Rather, the electric motor / gear block 48 a flexible shaft 55 on, at the end of the pinion 50 sitting. After mounting the Bowden window lifter 1 on the second assembly shot 51 becomes the pinion 50 by a corresponding displacement of the shaft 55 with the gear 35 coupled. In this respect, the attachment of the Bowden window lifter 1 on the second assembly shot 51 and the coupling of the adjustable Bowdenendstücks 17 to the electric motor / gear block 48 decoupled. The assembly is simplified thereby.

On the second assembly shot 51 are position sensors 52 . 52 ' firmly mounted. Both position sensors 52 . 52 ' are designed as mechanical sensors which mechanically linearly displaceable position elements according to defined reference points on the first driver 6 and at the second driver 7 scan. A simple calibration of the acquired measured values can affect the level of both drivers 6 . 7 calculated back and so the level adjustment be made.

For an automated level adjustment is the electric motor / gear block 48 with an electronic interface 53 equipped with a control device 54 communicates. The control device 54 includes in the example sketched here the measuring device 22 that measures the readings of the position sensors 52 . 52 ' detected. The control device 54 is formed, depending on the detected measured values or on the determined level position between the two drivers 6 . 7 the electric motor / gearbox block 48 to control accordingly until the desired level adjustment between the drivers 6 . 7 achieved. The illustrated adjustment device 56 significantly simplifies the level adjustment of the drivers 6 . 7 the Bowden window lifter 1 before final assembly.

The Bowden window lifter 1 is on the second assembly shot 51 aligned in the installed state according to the later positioning on a motor vehicle door. After the level adjustment of the drivers 6 . 7 Can the Bowden window lifter 1 the mounting receptacle 51 removed and transported to the assembly site. About the self-locking of the threaded connection 26 is a rotation of the adjustment 23 excluded during transport. Where appropriate, by the in 4 shown anti-rotation 42 any distortion excluded.

Changes the position of the drivers 6 . 7 due to aging or wear of individual components of the Bowden window lifter 1 in daily use, so can in a workshop by means of an open-end wrench, which with the polygon 32 coupled, done in a simple way, a manual readjustment.
