Definitions
- the invention relates to a motor vehicle with at least one pivotally mounted vehicle door comprising a door body and a frameless window pane which can be moved into and out of the door body.
- Vehicle doors with such windows are also referred to as frameless doors.
- Such a door is off DE 3119701 A known.
- the window pane is movable into and out of the door body via a suitable window lifting motor.
- the disc is guided vertically on a rail guide located in the region of the door articulation, the opposite disc side edge is not guided.
- On the door body a narrow longitudinal gap is provided on the upper side, through which the window pane is moved.
- the channel strip comprises two soft sealing lips, which lie on both sides of the window pane. They are movable to prevent squeaking noise when moving the window.
- the frameless window pane Due to the only one-sided guidance of the frameless window pane, it is movable in a direction perpendicular to the pane surface by a few millimeters, whereby the movement is ultimately limited by the chess strip. If the door is moved, for example, by the driver, it is especially when closing the door, which is relatively lively and the door against the Anlagenchassi falls into the castle, to increased vibrations of the vehicle window, especially in the area of the free, ungauged wheel rim, which is associated with noise is.
- the invention is therefore based on the problem to provide a motor vehicle in which such moving noise resulting from the mobility of the window can be avoided when moving the door.
- the motor vehicle according to the invention is characterized in that the window pane is actively fixed in its position by jamming, so that it is immovably fixed during a door movement.
- the clamp is actively de-activated when needed and the window is released so that it can be moved vertically if required, which is either required for opening and closing, or when opening the door a short-stroke for lowering or closing the door to lift is required.
- the device for active clamping and releasing of the window is located inside the door body, so it is completely installed in the carcass and can attack at any window position on the window for clamping. This ensures that the disc can be securely fixed in any position and even with violent door movements or blows does not lead to excessive disc movement, especially in the area of the sealing channel strip.
- the region of the largest disc acceleration is given in the region of the free, ie unguided, disc side edge, which thus runs adjacent to the free edge of the door.
- the device in the region of the vertical edge of the window, which runs adjacent to the free edge of the door, to position, so that the means for clamping acts on this disc side edge. It has proved sufficient when the device locally, ie punctually attacks in this area to prevent movement.
- the clamping device comprises two clamping elements acting on the disk surfaces, which are adjustable between a clamping position clamping the window pane and a release position releasing the window pane.
- the clamping device thus engages on both sides with a respective clamping element on the disc surfaces, the clamping elements are arranged opposite to each other, so that a secure, quasi "punctual" jamming of the disc between them is possible.
- the clamping elements are movable, d. h., They can be adjusted between a clamping position and a release position in which they do not attack on the disc, as will be discussed below. This makes it possible in a simple manner, on the one hand always clamp, if necessary, on the other hand to release the disc when a disc movement is pending.
- a particularly advantageous development of the invention provides to bring the clamping elements against a restoring force from the clamping position into the release position.
- This makes it possible for the clamping elements to be moved automatically into the clamping position via the restoring force. From this clamping position they are moved to release the window against the restoring force, which is built or reinforced during this movement. This movement is supported by adjusting elements, which will be discussed below.
- This embodiment is particularly expedient in that the disc is only relatively rarely released, even if a generally only very short lasting disc movement is required. Most of the time she is stuck. After this terminal takes place due to restoring force automatically and without energy consumption, and only the movement is supported in the release position, this embodiment is particularly useful in terms of energy consumption.
- a spring element is expediently provided, which preferably also has a prestressing in the clamping position located in the clamping elements, so that always a sufficiently strong contact of the clamping elements is given to the disc in the clamping position.
- the two spring elements are further stretched when moving into the release position, so that the restoring force is increased to automatically return the clamping elements for clamping in the clamping position.
- the restoring force is built up by the clamping element during the movement from the clamping position into the release position itself. This is possible when using suitable restoring elements, which will be discussed below.
- a first variant of the invention provides for the clamping elements to be designed as pivotally mounted clamping jaws, which can be brought in each case via an actuating device at least from the clamping position into the release position.
- the jaws are to adjust between the two positions by a certain angle, for example 45 °, to pivot, of course, larger or smaller angle can be realized.
- the movement must in any case be such that there is a sufficiently large distance between the jaws to release the disc.
- An alternative provides to perform the clamping elements as movable on each of a ramp-shaped guide surface clamping wedges, which can be brought in each case via an actuating device at least from the clamping position into the release position.
- a linear movement of the running as a clamping wedges clamping elements are designed so that the clamping wedges move towards each other and come into contact with the disc surfaces, and vice versa.
- a servomotor provided, in particular a servomotor, which is coupled directly or indirectly with a clamping element.
- a servomotor provided, in particular a servomotor, which is coupled directly or indirectly with a clamping element.
- both the jaws and the clamping wedges can be moved, it is only in the case of a jaw make sure that via the respective servo motor by direct or indirect coupling with a jaw pivotal movement of the baking takes place.
- a linear wedge movement is to be accomplished via the servo motor by direct or indirect coupling with a clamping wedge.
- a clamping element can be arranged directly on an output shaft of the servo motor, or be connected to the servo motor via a tension member, in particular a pull wire.
- a direct arrangement of a clamping element on the engine output shaft is useful in particular in execution of the clamping element as jaws. Because due to the rotation of the output shaft, a pivoting movement of the jaw is automatically enabled.
- the clamping element be it designed as a jaw or clamping wedge, be connected via a tensile member such as a pull wire or a tie rod to the engine.
- the servomotor pulls for moving the jaw or the clamping wedge from the clamping position in the release position to the tensile part, it winds, for example, when using a pull wire, about which the clamping element is moved from the clamping position against the restoring force.
- the servo motor if it is a servo motor, not continue to operate, so that it is no resistance and the clamping element can be automatically returned by the restoring force. If no restoring force is provided, that is, if, for example, no spring element is integrated, by using a rigid tension member such as, for example, a pull rod, a movement effected via the motor can take place in both directions.
- An alternative to the use of a servomotor provides for the use of a modifiable by applying a current or a magnetic field in its form actuator, which is coupled directly or indirectly with a clamping element.
- a modifiable by applying a current or a magnetic field in its form actuator acts primarily as a tensile part. Depending on the configuration of the actuator this is changeable in its shape by applying a current or a magnetic field. As a result, a considerable change in length can be realized in the execution of the actuator as an elongate tension member, about which a sufficient train or movement path of the coupled clamping element can be accomplished.
- a jaw connected to a pull wire actuator it can be changed in shape, for example, by energizing and a resulting heating, it shortens, resulting in the Klemmbackenverschwenkung.
- Such an actuator can for example consist of a shape memory alloy, which assumes a first shape at room temperature and when heated by applying a current or upon application of a magnetic field, a second shape.
- a bimetal component which also assumes a second form in the event of heating.
- such an actuator is designed as a tensile part, in particular as a pull wire, as a result of the Switzerlandteilin in the case of change in shape, a sufficient change in length can be achieved.
- a further alternative embodiment of the clamping elements provides to perform the clamping elements themselves as modifiable by applying a current or a magnetic field in its form actuators occupy the clamping position in one form and the release position in the other form.
- the device is not two components used (clamping element and adjusting device), but only a component, namely the clamping element itself, which is virtually its own actuator due to its design as a variable shape actuator. If two such clamping elements are provided on both sides of the window pane, then they are without energization respectively without external magnetic field in a first form, in which they rest clamped on the disc surfaces. When energized, ie heating or applying a magnetic field, they change their shape and go into the release position.
- a controlled clamping and releasing can be realized in a simple manner. Under certain circumstances, such clamping elements can build up their own restoring force.
- a clamping element as this is carried out, a friction or adhesive coating, with which it acts on the disk surface on.
- a friction or adhesive coating may for example be a plastic pad, for example an elastomer, or the like.
- a control device controlling the operation of the device which controls the device as a function of at least one signal indicating an impending movement of the windowpane .
- a window switch, a door opening switch or a door lock can serve for the administration of such a signal.
- a device is used for this purpose, upon actuation of which it is certain that a window pane movement will be required shortly thereafter.
- the device is a window switch which is actuated, for example, by the driver, then this is pressed, for example, to lower the window pane, whereupon a signal is immediately given to the control device controlling the clamping device, which immediately activates the setting device, for example, so that the Clamping be solved, whereupon the window lift takes place.
- a signal from the control device to the actuator is given, so that the clamping elements are moved back into the clamping position.
- a door opening switch as the signaling device.
- the driver wants to get on or off, he attacks either the outer or the inner door handle.
- a short lowering movement of the disc is required.
- the attack on the door handle is detected by a suitable door opening switch, which gives the corresponding control signal to the controller, which initiates the release of the disc clamping and, after the short stroke of the disc is completed, immediately re-initiates the clamping of the disc.
- Fig. 1 shows a motor vehicle 1 according to the invention with a pivotally mounted vehicle door 2 comprising a door body 3, in which a movable frameless window 4 is received, which is movable via a not shown in detail lifting motor in and out of the door body 3.

- the motion is controlled by a control device 9 in response to a signal, for example given by a sensor in the region of the outer door handle 10 or the inner door handle 11. If one of these handles a sensor signal given that the driver attacks it, so it is in the invention
- Motor vehicle 1 for example, required to open the closed vehicle door 2, the window 4 to lower a short distance to facilitate the opening.
- the control device 9 immediately causes the respective clamping elements 7 to be moved into the release position via the adjusting device 8, after which the window pane 4 is moved, whereupon the clamping elements 7 are immediately applied again and the window pane 4 is locked.
- Another device, via which a corresponding sensor signal can be given to the control device 9, is, for example, the door lock, via which the vehicle door 2 is locked in the closed state.
- the door lock via which the vehicle door 2 is locked in the closed state.
- the clamping elements 7 are again briefly to be released and then brought back into the clamping position. D. h. That ultimately a release of the clamping elements 7 from its clamping position is only required if immediately followed by a window pane movement.

Description
Die Erfindung betrifft ein Kraftfahrzeug mit wenigstens einer schwenkbar gelagerten Fahrzeugtür umfassend einen Türkorpus und eine in den und aus dem Türkorpus bewegbare rahmenlose Fensterscheibe.The invention relates to a motor vehicle with at least one pivotally mounted vehicle door comprising a door body and a frameless window pane which can be moved into and out of the door body.
Fahrzeugtüren mit solchen Fensterscheiben werden auch als rahmenlose Türen bezeichnet. Eine solche Tür ist aus
Vornehmlich bei Cabriolets und Coupes werden zunehmend Fahrzeugtüren mit rahmenlosen Fensterscheiben verbaut. Die Fensterscheibe ist in den und aus dem Türkorpus über einen geeigneten Fensterhebemotor bewegbar. Die Scheibe ist an einer im Bereich der Türanlenkung befindlichen Schienenführung vertikal geführt, die gegenüberliegende Scheibenseitenkante ist nicht geführt. Am Türkorpus ist oberseitig ein schmaler Längsspalt vorgesehen, durch den die Fensterscheibe bewegt wird. Dort befindet sich eine sogenannte Schachtleiste, die sich längs des Türkorpus beidseits der, Fensterscheibe erstreckt. Sie dient der Abdichtung zwischen Türkorpus und Fensterscheibe, damit ein Eindringen insbesondere von Wasser aber auch von Wind in den Türkorpus verhindert wird. Die Schachtleiste umfasst zwei weiche Dichtlippen, die sich beidseits an die Fensterscheibe legen. Sie sind beweglich, damit vermieden wird, dass es beim Bewegen der Fensterscheibe zu Quietschgeräuschen kommt.Especially in convertibles and coupes, vehicle doors with frameless windows are increasingly being installed. The window pane is movable into and out of the door body via a suitable window lifting motor. The disc is guided vertically on a rail guide located in the region of the door articulation, the opposite disc side edge is not guided. On the door body, a narrow longitudinal gap is provided on the upper side, through which the window pane is moved. There is a so-called manhole, which extends along the door body on both sides of the window. It serves to seal between the door body and window, so that penetration of water in particular but also of wind in the door body is prevented. The channel strip comprises two soft sealing lips, which lie on both sides of the window pane. They are movable to prevent squeaking noise when moving the window.
Aufgrund der nur einseitigen Führung der rahmenlosen Fensterscheibe ist diese in einer Richtung senkrecht zur Scheibenfläche um wenige Millimeter beweglich, wobei die Bewegung letztlich durch die Schachtleiste begrenzt ist. Wird die Tür beispielsweise vom Fahrer bewegt, so kommt es insbesondere beim Schließen der Tür, was relativ schwungvoll erfolgt und wobei die Tür gegen das Fahrzeugchassi ins Schloss fällt, zu verstärkten Schwingungen der Fahrzeugscheibe insbesondere im Bereich der freien, ungeführten Scheibenkante, was mit Geräuschen verbunden ist.Due to the only one-sided guidance of the frameless window pane, it is movable in a direction perpendicular to the pane surface by a few millimeters, whereby the movement is ultimately limited by the chess strip. If the door is moved, for example, by the driver, it is especially when closing the door, which is relatively lively and the door against the Fahrzeugchassi falls into the castle, to increased vibrations of the vehicle window, especially in the area of the free, ungauged wheel rim, which is associated with noise is.
Der Erfindung liegt damit das Problem zugrunde, ein Kraftfahrzeug anzugeben, bei dem beim Bewegen der Tür derartige aus der Beweglichkeit der Fensterscheibe resultierende Geräusche vermieden werden.The invention is therefore based on the problem to provide a motor vehicle in which such moving noise resulting from the mobility of the window can be avoided when moving the door.
Zur Lösung dieses Problem ist bei einem Kraftfahrzeug der eingangs genannten Art erfindungsgemäß vorgesehen, dass eine im Inneren des Türkorpus angeordnete, bedarfsabhängig betätigbare Einrichtung zum aktiven Klemmen und Freigeben der Fensterscheibe vorgesehen ist.To solve this problem is provided according to the invention in a motor vehicle of the type mentioned that an arranged inside the door body, demand-responsive device is provided for active clamping and releasing the window.
Das erfindungsgemäße Kraftfahrzeug zeichnet sich dadurch aus, dass die Fensterscheibe aktiv durch Verklemmen in ihrer Position fixiert wird, so dass sie bei einer Türbewegung unbeweglich fixiert ist. Die Klemmhalterung wird bei Bedarf aktiv aufgehoben und die Fensterscheibe freigegeben, so dass sie, wenn erforderlich, vertikal bewegt werden kann, was entweder zum Öffnen und Schließen erforderlich ist, oder wenn zum Öffnen der Tür ein Kurzhub zum Absenken respektive beim Schließen der Tür zum Anheben erforderlich ist.The motor vehicle according to the invention is characterized in that the window pane is actively fixed in its position by jamming, so that it is immovably fixed during a door movement. The clamp is actively de-activated when needed and the window is released so that it can be moved vertically if required, which is either required for opening and closing, or when opening the door a short-stroke for lowering or closing the door to lift is required.
Die Einrichtung zum aktiven Klemmen und Freigeben der Fensterscheibe befindet sich im Inneren des Türkorpus, ist also vollständig im Korpus verbaut und kann in jeder Fensterscheibenposition an der Scheibe zum Klemmen angreifen. Hierüber ist sichergestellt, dass die Scheibe in jeder Position sicher fixiert werden kann und es auch bei heftigen Türbewegungen bzw. Schlägen nicht zu einer übermäßigen Scheibenbewegung insbesondere im Bereich der abdichtenden Schachtleiste kommt.The device for active clamping and releasing of the window is located inside the door body, so it is completely installed in the carcass and can attack at any window position on the window for clamping. This ensures that the disc can be securely fixed in any position and even with violent door movements or blows does not lead to excessive disc movement, especially in the area of the sealing channel strip.
Es hat sich herausgestellt, dass der Bereich der größten Scheibenbeschleunigung im Bereich der freien, also ungeführten Scheibenseitenkante, die also benachbart zur freien Türkante verläuft, gegeben ist. Infolgedessen sieht eine zweckmäßige Weiterbildung der Erfindung vor, die Einrichtung im Bereich der vertikalen Scheibenkante, die benachbart zur freien Türkante verläuft, zu positionieren, so dass die Einrichtung zum Klemmen an dieser Scheibenseitenkante angreift. Es hat sich als ausreichend erwiesen, wenn die Einrichtung lokal, also punktuell in diesen Bereich angreift, um eine Bewegung zu verhindern.It has been found that the region of the largest disc acceleration is given in the region of the free, ie unguided, disc side edge, which thus runs adjacent to the free edge of the door. As a result, an expedient embodiment of the invention, the device in the region of the vertical edge of the window, which runs adjacent to the free edge of the door, to position, so that the means for clamping acts on this disc side edge. It has proved sufficient when the device locally, ie punctually attacks in this area to prevent movement.
Um eine sichere Klemmung zu ermöglichen sieht eine zweckmäßige Weiterbildung der Erfindung vor, dass die Klemmeinrichtung zwei an den Scheibenflächen angreifende Klemmelemente umfasst, die zwischen einer die Fensterscheibe klemmenden Klemmstellung und einer die Fensterscheibe freigebenden Lösestellung verstellbar sind. Die Klemmeinrichtung greift also beidseitig mit jeweils einem Klemmelement an den Scheibenflächen an, die Klemmelemente sind einander gegenüberliegend angeordnet, so dass eine sichere, quasi "punktuelle" Verklemmung der Scheibe zwischen ihnen möglich ist. Die Klemmelemente sind beweglich, d. h., sie können zwischen einer Klemmstellung und einer Lösestellung, in der sie nicht an der Scheibe angreifen, verstellt werden, worauf nachfolgend noch eingegangen wird. Hierüber ist es auf einfache Weise möglich, einerseits stets dann zu klemmen, wenn dies erforderlich ist, andererseits die Scheibe freizugeben, wenn eine Scheibenbewegung ansteht.To enable secure clamping, an expedient development of the invention provides that the clamping device comprises two clamping elements acting on the disk surfaces, which are adjustable between a clamping position clamping the window pane and a release position releasing the window pane. The clamping device thus engages on both sides with a respective clamping element on the disc surfaces, the clamping elements are arranged opposite to each other, so that a secure, quasi "punctual" jamming of the disc between them is possible. The clamping elements are movable, d. h., They can be adjusted between a clamping position and a release position in which they do not attack on the disc, as will be discussed below. This makes it possible in a simple manner, on the one hand always clamp, if necessary, on the other hand to release the disc when a disc movement is pending.
Eine besonders zweckmäßige Weiterbildung der Erfindung sieht vor, die Klemmelemente gegen eine Rückstellkraft aus der Klemmstellung in die Lösestellung zu bringen. Dies ermöglicht es, dass die Klemmelemente automatisch in die Klemmstellung über die Rückstellkraft bewegt werden. Aus dieser Klemmstellung werden sie zum Freigeben der Fensterscheibe gegen die Rückstellkraft bewegt, die während dieser Bewegung aufgebaut oder verstärkt wird. Diese Bewegung wird über Stellelemente unterstützt, worauf nachfolgend noch eingegangen wird. Diese Ausführungsform ist insbesondere dahingehend zweckmäßig, als die Scheibe nur relativ selten freizugeben ist, eben dann, wenn eine in der Regel nur sehr kurz dauernde Scheibenbewegung erforderlich ist. Die meiste Zeit ist sie zu klemmen. Nachdem dieses Klemmen rückstellkraftbedingt automatisch und ohne Energieaufwand erfolgt, und lediglich die Bewegung in die Lösestellung unterstützt erfolgt, ist diese Ausgestaltung im Hinblick auf den Energieverbrauch besonders zweckmäßig.A particularly advantageous development of the invention provides to bring the clamping elements against a restoring force from the clamping position into the release position. This makes it possible for the clamping elements to be moved automatically into the clamping position via the restoring force. From this clamping position they are moved to release the window against the restoring force, which is built or reinforced during this movement. This movement is supported by adjusting elements, which will be discussed below. This embodiment is particularly expedient in that the disc is only relatively rarely released, even if a generally only very short lasting disc movement is required. Most of the time she is stuck. After this terminal takes place due to restoring force automatically and without energy consumption, and only the movement is supported in the release position, this embodiment is particularly useful in terms of energy consumption.
Zur Erzeugung der Rückstellkraft ist zweckmäßigerweise ein Federelement vorgesehen, das bevorzugt auch bei in der Klemmstellung befindlichen Klemmelementen eine Vorspannung besitzt, so dass stets eine hinreichend kräftige Anlage der Klemmelemente an der Scheibe in der Klemmstellung gegeben ist. Die beiden Federelemente (jedem Klemmelement ist bevorzugt ein eigenes Federelement zugeordnet) werden beim Bewegen in die Lösestellung noch weiter gespannt, so dass die Rückstellkraft vergrößert wird, um die Klemmelemente zum Verklemmen automatisch in die Klemmstellung zurückzuführen. Alternativ ist es auch denkbar, dass die Rückstellkraft vom Klemmelement während der Bewegung von der Klemmstellung in die Lösestellung selbst aufgebaut wird. Dies ist bei Verwendung geeigneter Rückstellelemente, worauf nachfolgend noch eingegangen wird, möglich.To generate the restoring force, a spring element is expediently provided, which preferably also has a prestressing in the clamping position located in the clamping elements, so that always a sufficiently strong contact of the clamping elements is given to the disc in the clamping position. The two spring elements (each clamping element is preferably associated with a separate spring element) are further stretched when moving into the release position, so that the restoring force is increased to automatically return the clamping elements for clamping in the clamping position. Alternatively, it is also conceivable that the restoring force is built up by the clamping element during the movement from the clamping position into the release position itself. This is possible when using suitable restoring elements, which will be discussed below.
Die Klemmelemente selbst können in unterschiedlicher Form realisiert sein. Eine erste erfindungsgemäße Ausführungsvariante sieht vor, die Klemmelemente als schwenkbar gelagerte Klemmbacken auszuführen, die jeweils über eine Stelleinrichtung zumindest von der Klemmstellung in die Lösestellung bringbar sind. Die Klemmbacken sind zum Verstellen zwischen den beiden Stellungen um einen bestimmten Winkel, beispielsweise 45°, zu verschwenken, wobei natürlich auch größere oder kleinere Winkel realisiert werden können. Die Bewegung muss in jedem Fall derart sein, dass sich ein hinreichend großer Abstand zwischen den Klemmbacken ergibt, um die Scheibe freizugeben.The clamping elements themselves can be realized in different forms. A first variant of the invention provides for the clamping elements to be designed as pivotally mounted clamping jaws, which can be brought in each case via an actuating device at least from the clamping position into the release position. The jaws are to adjust between the two positions by a certain angle, for example 45 °, to pivot, of course, larger or smaller angle can be realized. The movement must in any case be such that there is a sufficiently large distance between the jaws to release the disc.
Eine Alternative sieht vor, die Klemmelemente als auf jeweils einer rampenförmigen Führungsfläche bewegbare Klemmkeile auszuführen, die jeweils über eine Stelleinrichtung zumindest von der Klemmstellung in die Lösestellung bringbar sind. Bei dieser Erfindungsausgestaltung erfolgt also, anders als bei der Schwenklagerung der Klemmbacken, eine lineare Bewegung der als Klemmkeile ausgeführten Klemmelemente. Diese laufen hierbei auf einer rampenförmigen Führungsfläche auf, die so ausgestaltet ist, dass sich die Klemmkeile aufeinander zubewegen und in Anlage an die Scheibenflächen kommen, und umgekehrt.An alternative provides to perform the clamping elements as movable on each of a ramp-shaped guide surface clamping wedges, which can be brought in each case via an actuating device at least from the clamping position into the release position. In this embodiment of the invention, therefore, unlike the pivotal mounting of the jaws, a linear movement of the running as a clamping wedges clamping elements. These run on a ramp-shaped guide surface, which is designed so that the clamping wedges move towards each other and come into contact with the disc surfaces, and vice versa.
Zum Bewegen der Klemmelemente zumindest von der Klemmstellung in die Lösestellung (während welcher Bewegung bevorzugt eine Rückstellkraft aufgebaut wird, die für eine automatische Rückführung in die Klemmstellung sorgt, so dass nur eine aktiv unterstützte Ein-Weg-Bewegung zu realisieren ist) ist als Stelleinrichtung zweckmäßigerweise ein Stellmotor vorgesehen, insbesondere ein Servomotor, der direkt oder indirekt mit einem Klemmelement gekoppelt ist. Über solche Stellmotoren können sowohl die Klemmbacken als auch die Klemmkeile bewegt werden, es ist lediglich im Falle einer Klemmbackenausführung dafür zu sorgen, dass über den jeweiligen Stellmotor durch direkte oder indirekte Kopplung mit einem Klemmbacken eine Schwenkbewegung des Backens erfolgt. Im Fall der Keilausführung der Klemmelemente ist über den Stellmotor durch direkt oder indirekte Kopplung mit einem Klemmkeil eine lineare Keilbewegung zu bewerkstelligen.To move the clamping elements at least from the clamping position to the release position (during which movement preferably a restoring force is built up, which ensures an automatic return to the clamping position, so that only one actively supported one-way movement is to be realized) is expediently as adjusting device a servomotor provided, in particular a servomotor, which is coupled directly or indirectly with a clamping element. About such servomotors, both the jaws and the clamping wedges can be moved, it is only in the case of a jaw make sure that via the respective servo motor by direct or indirect coupling with a jaw pivotal movement of the baking takes place. In the case of the wedge design of the clamping elements a linear wedge movement is to be accomplished via the servo motor by direct or indirect coupling with a clamping wedge.
Dabei kann ein Klemmelement direkt auf einer Abtriebswelle des Stellmotors angeordnet sein, oder mit dem Stellmotor über ein Zugteil, insbesondere einen Zugdraht verbunden sein. Eine direkt Anordnung eines Klemmelements auf der Motorabtriebswelle ist insbesondere bei Ausführung des Klemmelements als Klemmbacken zweckmäßig. Denn aufgrund der Rotation der Abtriebswelle wird automatisch eine Schwenkbewegung des Klemmbackens ermöglicht. Gleichermaßen kann das Klemmelement, sei es als Klemmbacke oder als Klemmkeil ausgeführt, über ein Zugteil wie beispielsweise einen Zugdraht oder eine Zugstange mit dem Motor verbunden sein. Der Stellmotor zieht zum Bewegen des Klemmbackens oder des Klemmkeils aus der Klemmstellung in die Lösestellung das Zugteil an, wickelt es beispielsweise bei Verwendung eines Zugdrahts auf, worüber das Klemmelement aus der Klemmstellung gegen die Rückstellkraft bewegt wird. Zum Zurückbewegen wird beispielsweise der Stellmotor, sofern es sich um einen Servomotor handelt, nicht weiterbetrieben, so dass er keinen Widerstand darstellt und das Klemmelement automatisch über die Rückstellkraft zurückgeführt werden kann. Ist keine Rückstellkraft gegeben, ist also beispielsweise kein Federelement integriert, so kann durch Verwendung eines starren Zugteils wie beispielsweise einer Zugstange eine über den Motor bewerkstelligte Bewegung in beide Richtungen erfolgen.In this case, a clamping element can be arranged directly on an output shaft of the servo motor, or be connected to the servo motor via a tension member, in particular a pull wire. A direct arrangement of a clamping element on the engine output shaft is useful in particular in execution of the clamping element as jaws. Because due to the rotation of the output shaft, a pivoting movement of the jaw is automatically enabled. Similarly, the clamping element, be it designed as a jaw or clamping wedge, be connected via a tensile member such as a pull wire or a tie rod to the engine. The servomotor pulls for moving the jaw or the clamping wedge from the clamping position in the release position to the tensile part, it winds, for example, when using a pull wire, about which the clamping element is moved from the clamping position against the restoring force. To move back, for example, the servo motor, if it is a servo motor, not continue to operate, so that it is no resistance and the clamping element can be automatically returned by the restoring force. If no restoring force is provided, that is, if, for example, no spring element is integrated, by using a rigid tension member such as, for example, a pull rod, a movement effected via the motor can take place in both directions.
Eine Alternative zur Verwendung eines Stellmotors sieht den Einsatz eines durch Anlegen eines Stroms oder eines Magnetfelds in seiner Form veränderbaren Aktors vor, der direkt oder indirekt mit einem Klemmelement gekoppelt ist. Ein solcher Aktor wirkt vornehmlich als Zugteil. Je nach Ausgestaltung des Aktors ist dieser durch Anlegen eines Stroms oder eines Magnetfelds in seiner Form veränderbar. Hierdurch kann bei Ausführung des Aktors als längliches Zugteil eine beachtliche Längenveränderung realisiert werden, worüber ein hinreichender Zug- oder Bewegungsweg des gekoppelten Klemmelements bewerkstelligt werden kann. 1st also beispielsweise ein Klemmbacken mit einem Zugdraht-Aktor verbunden, so kann dieser beispielsweise durch Bestromen und einer daraus resultierenden Erwärmung in seiner Form verändert werden, er verkürzt sich, woraus die Klemmbackenverschwenkung erfolgt. In gleicher Weise kann hierüber auch die Linearbewegung eines Klemmkeils gesteuert werden. Ein solcher Aktor kann beispielsweise aus einer Formgedächtnislegierung bestehen, die bei Raumtemperatur eine erste Form und bei Erwärmung durch Anlegen eines Stroms oder bei Anlegen eines Magnetfelds eine zweite Form einnimmt. Denkbar ist aber auch die Ausführungsform eines solchen Aktors als Bimetall-Bauteil, das im Falle einer Erwärmung ebenfalls eine zweite Form einnimmt. Bevorzugt ist ein solcher Aktor als Zugteil, insbesondere als Zugdraht ausgebildet, da infolge der Zugteillänge im Falle der Formänderung eine hinreichende Längenänderung erreicht werden kann.An alternative to the use of a servomotor provides for the use of a modifiable by applying a current or a magnetic field in its form actuator, which is coupled directly or indirectly with a clamping element. Such an actuator acts primarily as a tensile part. Depending on the configuration of the actuator this is changeable in its shape by applying a current or a magnetic field. As a result, a considerable change in length can be realized in the execution of the actuator as an elongate tension member, about which a sufficient train or movement path of the coupled clamping element can be accomplished. So for example, if a jaw connected to a pull wire actuator, it can be changed in shape, for example, by energizing and a resulting heating, it shortens, resulting in the Klemmbackenverschwenkung. In the same way can also be controlled by the linear movement of a clamping wedge. Such an actuator can for example consist of a shape memory alloy, which assumes a first shape at room temperature and when heated by applying a current or upon application of a magnetic field, a second shape. It is also conceivable embodiment of such an actuator as a bimetal component, which also assumes a second form in the event of heating. Preferably, such an actuator is designed as a tensile part, in particular as a pull wire, as a result of the Zugteillänge in the case of change in shape, a sufficient change in length can be achieved.
Eine weitere alternative Ausführung der Klemmelemente sieht vor, die Klemmelemente selbst als durch Anlegen eines Stroms oder eines Magnetfelds in seiner Form veränderbare Aktoren auszuführen, die in der einen Form die Klemmstellung und in der anderen Form die Lösestellung einnehmen. Bei dieser Erfindungsalternative kommen also zur Realisierung der Einrichtung keine zwei Bauteile zum Einsatz (Klemmelement und Stelleinrichtung), sondern nur ein Bauteil, nämlich das Klemmelement selbst, das aufgrund seiner Ausführung als formveränderlicher Aktor quasi seine eigene Stelleinrichtung ist. Sind beidseits der Fensterscheibe zwei derartige Klemmelemente vorgesehen, so befinden sich diese ohne Bestromung respektive ohne externes Magnetfeld in einer ersten Form, in der sie klemmend an den Scheibenflächen anliegen. Bei Bestromung, also Erwärmung respektive Anlegen eines Magnetfelds ändern sie ihre Form und gehen in die Lösestellung über. Auch hierüber kann auf einfache Weise ein gesteuertes Klemmen und Freigeben realisiert werden. Solche Klemmelemente können unter Umständen eine eigene Rückstellkraft aufbauen.A further alternative embodiment of the clamping elements provides to perform the clamping elements themselves as modifiable by applying a current or a magnetic field in its form actuators occupy the clamping position in one form and the release position in the other form. In this invention alternative so come to realize the device is not two components used (clamping element and adjusting device), but only a component, namely the clamping element itself, which is virtually its own actuator due to its design as a variable shape actuator. If two such clamping elements are provided on both sides of the window pane, then they are without energization respectively without external magnetic field in a first form, in which they rest clamped on the disc surfaces. When energized, ie heating or applying a magnetic field, they change their shape and go into the release position. Here too, a controlled clamping and releasing can be realized in a simple manner. Under certain circumstances, such clamping elements can build up their own restoring force.
Zweckmäßigerweise weist ein Klemmelement, gleich wie dieses ausgeführt ist, einen Reib- oder Haftbelag, mit dem es an der Scheibenfläche angreift, auf. Ein solcher Reib- oder Haftbelag kann beispielsweise eine Kunststoffauflage, beispielsweise ein Elastomer, oder dergleichen sein.Conveniently, a clamping element, as this is carried out, a friction or adhesive coating, with which it acts on the disk surface on. Such a friction or adhesive coating may for example be a plastic pad, for example an elastomer, or the like.
Wie bereits einleitend beschrieben, ist die Klemmung nur dann zu lösen, wenn eine Fensterbewegung ansteht. Um die Einrichtung nur dann zu betätigen und die Klemmelemente von der Klemm- und Lösestellung zu bewegen, wenn dies erforderlich ist, ist zweckmäßigerweise eine den Betrieb der Einrichtung steuernde Steuerungseinrichtung vorgesehen, die die Einrichtung in Abhängigkeit wenigstens eines eine anstehende Bewegung der Fensterscheibe anzeigenden Signals steuert. Zur Gabe eines solchen Signals kann beispielsweise ein Fensterschalter, ein Türöffnungsschalter oder ein Türschloss dienen. In jedem Fall wird hierzu also eine Vorrichtung verwendet, bei deren Betätigung sicher ist, dass kurz darauf eine Fensterscheibenbewegung erforderlich ist. Handelt es sich bei der Vorrichtung um einen Fensterschalter, der beispielsweise vom Fahrer betätigt wird, so wird dieser beispielsweise zum Absenken der Fensterscheibe gedrückt, woraufhin sofort ein Signal an die die Klemmeinrichtung steuernde Steuerungseinrichtung gegeben wird, die umgehend beispielsweise die Stelleinrichtung ansteuert, so dass die Klemmelemente gelöst werden, woraufhin der Fensterhub erfolgt. Nach Beendigung des Fensterhubs, wenn also entweder der Fensterschalter nicht mehr betätigt wird respektive bei einmaliger Betätigung des Fensterschalters und darauf hin erfolgender vollständiger Absenkung oder Anhebung der Fensterscheibe die Endposition erreicht ist, wird sofort wieder ein Signal von der Steuerungseinrichtung an die Stelleinrichtung gegeben, so dass die Klemmelemente wieder in die Klemmstellung bewegt werden. Gleiches kann durch Verwendung eines Türöffnungsschalters als signalgebende Vorrichtung erreicht werden. Möchte der Fahrer ein- oder aussteigen, so greift er entweder am äußeren oder am inneren Türgriff an. Beim Öffnen der Tür ist eine kurze Absenkbewegung der Scheibe erforderlich. Der Angriff am Türgriff wird über einen geeigneten Türöffnungsschalter erfasst, der das entsprechende Steuerungssignal an die Steuerungseinrichtung gibt, die das Lösen der Scheibenklemmung einleitet und, nachdem der Kurzhub der Scheibe beendet ist, sofort wieder die Klemmung der Scheibe einleitet.As already described in the introduction, the clamping is only to be solved when a window movement is pending. In order to actuate the device only and to move the clamping elements from the clamping and release position, if necessary, a control device controlling the operation of the device is expediently provided, which controls the device as a function of at least one signal indicating an impending movement of the windowpane , For example, a window switch, a door opening switch or a door lock can serve for the administration of such a signal. In any case, therefore, a device is used for this purpose, upon actuation of which it is certain that a window pane movement will be required shortly thereafter. If the device is a window switch which is actuated, for example, by the driver, then this is pressed, for example, to lower the window pane, whereupon a signal is immediately given to the control device controlling the clamping device, which immediately activates the setting device, for example, so that the Clamping be solved, whereupon the window lift takes place. After completion of the window lift, so if either the window switch is no longer operated respectively with a single operation of the window switch and then complete complete lowering or raising the window the end position is reached, immediately a signal from the control device to the actuator is given, so that the clamping elements are moved back into the clamping position. The same can be achieved by using a door opening switch as the signaling device. If the driver wants to get on or off, he attacks either the outer or the inner door handle. When opening the door a short lowering movement of the disc is required. The attack on the door handle is detected by a suitable door opening switch, which gives the corresponding control signal to the controller, which initiates the release of the disc clamping and, after the short stroke of the disc is completed, immediately re-initiates the clamping of the disc.
