Description

Teileinheit zur Betätigung einer drehbar gelagerten Welle, deren aktueller Drehwinkel kontinuierlich zur erfassen istSubunit for actuating a rotatably mounted shaft whose current angle of rotation is to be detected continuously

Die Erfindung bezieht sich auf eine Teileinheit zur Betätigung einer drehbar gelagerten Welle, deren aktueller Drehwinkel kontinuierlich zu erfassen ist sowie auf eine Verwendung der Teileinheit. Drehbar gelagerte Wellen, deren aktueller Drehwinkel kontinuierlich zu erfassen ist, sind bekannt. Sie werden beispielsweise in Anzeigeninstrumenten eingesetzt, bei denen die Information über den jeweiligen Drehwinkel der drehbar gelagerten Welle eine große Bedeutung hat. Ferner sind solche drehbar gelagerten Wellen in Absperrorganen zu finden, bei denen der jeweilige aktuelle Drehwinkel Aussagen über den Öffnungsgrad der Absperrorgane ermöglicht. In der Regel ist der konstruktive Aufwand hierbei jedoch relativ hoch. Dies liegt daran, dass zum einen die drehbar gelagerte Welle angetrieben werden muss. Dies geschieht in der Regel durch die Anordnung von Elektromotoren, die durch elektrische Leitungen mit Strom versorgt werden müssen. Zum anderen müssen Drehwinkelsensoren angeordnet werden, wobei ebenfalls Leitungen für deren Stromversorgung sowie für deren Signalabgriff vorzusehen sind. Dabei ist es möglich, Baugruppen als Teileinheiten einzusetzen, wobei jedoch nachteilig ist, dass einzelne Teile konstruktiv aufwändig verlötet, verschraubt oder verschweißt werden müssen.The invention relates to a subunit for actuating a rotatably mounted shaft whose current angle of rotation is to be continuously detected and to a use of the subunit. Rotatable shafts whose current angle of rotation is to be continuously detected are known. They are used for example in display instruments, in which the information about the respective angle of rotation of the rotatably mounted shaft has a great importance. Furthermore, such rotatably mounted shafts are found in shut-off devices, in which the respective current angle of rotation makes statements about the opening degree of the shut-off devices possible. In general, however, the design effort is relatively high. This is because on the one hand, the rotatably mounted shaft must be driven. This is usually done by the arrangement of electric motors, which must be powered by electrical lines with electricity. On the other hand, rotational angle sensors must be arranged, with lines for their power supply and their signal tap are also provided. It is possible to use modules as subunits, but it is disadvantageous that individual parts have to be soldered constructively, screwed or welded.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Teileinheit zur Betätigung einer solchen drehbar gelagerten Welle zu schaffen, die relativ kompakt aufgebaut ist, wobei auf vielerlei Schweiß-, Löt- oder Schraubverbindungen verzichtet werden kann. Die Teileinheit soll auf relativ einfache Weise in Gehäusen integrierbar, beziehungsweise nachrüstbar sein. Ferner liegt der Erfindung die Aufgabe zugrunde, eine Verwendung der Teileinheit zu schaffen.The invention is therefore an object of the invention to provide a subunit for operating such a rotatably mounted shaft, which is relatively compact, with many welding, soldering or screw can be dispensed with. The subunit is to be integrated in a relatively simple manner in housings, or be retrofitted. Furthermore, the invention has for its object to provide a use of the subunit.

Die der Erfindung zugrunde liegende Aufgabe wird durch eine Teileinheit zur Betätigung einer drehbar gelagerten Welle, deren aktueller Drehwinkel kontinuierlich zu erfassen ist, gelöst, die aus einem Gitter aus Metallstreifen besteht und Steckerkontakte sowie eine erste Verbindung, die mit einer ersten Drossel verbunden ist, die wiederum mit einer ersten Motoranschlussfahne verbunden ist, und eine zweite Verbindung, die mit einer zweiten Drossel verbunden ist, die wiederum mit einer zweiten Motoranschlussfahne verbunden ist, aufweist und bei der das Gitter an einer Seite mittig mit einem berührungsfreien, magnetoresistiven Drehwinkelsensor verbunden ist, wobei das Gitter, die Steckerkontakte, die erste Verbindung, die zweite Verbindung sowie die erste Motoranschlussfahne und die zweite Motoranschlussfahne ganz oder teilweise von einer Ummantelung aus elektrisch nicht leitendem Kunststoff umgeben sind. Bei dem Gitter aus Metallstreifen handelt es sich um die Kontaktgitter, die handelsüblich unter der Bezeichnung "Leadframe" vertrieben werden. Die Steckerkontakte haben mehrere Funktionen. Einige von ihnen dienen der Stromversorgung eines Elektromotors über die erste Motoranschlussfahne und die zweite Motoranschlussfahne. Andere Steckerkontakte dienen der Stromversorgung des berührungsfreien, magnetoresistiven Drehwinkelsensors sowie der einzelnen Signalabgriffe. Bevorzugt sind für vielerlei Einsatzzwecke sechs Steckerkontakte vorgesehen. Zwei davon dienen der Stromversorgung des Elektromotors. Zwei weitere von Ihnen dienen der Stromversorgung des berührungsfreien, magnetoresistiven Drehwinkelsensors. Ferner sind zwei weitere Steckerkontakte für den Signalabgriff vorgesehen. In diesem Fall werden somit von dem berührungsfreien, magnetoresistiven Drehwinkelsensor zwei Signale erfasst und abgegriffen. Das Gitter, die Steckerkontakte, die erste Verbindung, die zweite Verbindung sowie die erste Motoranschlussfahne und die zweite Motoranschlussfahne sind ganz oder teilweise von einer Ummantelung aus elektrisch nicht leitendem Kunststoff umgeben. Dies bedeutet, dass beispielsweise Teilbereiche der ersten Verbindung oder der zweiten Verbindung oder des Gitters von diesem leitenden Kunststoff nicht umgeben sind. Dabei versteht es sich von selbst, dass die Steckerkontakte und die erste Motoranschlussfahne sowie die zweite Motoranschlussfahne nicht vollständig von dem elektrisch nicht leitenden Kunststoff umgeben sein dürfen. Es hat sich in überraschender Weise gezeigt, dass die Teileinheit zur Betätigung einer drehbar gelagerten Welle, deren aktueller Drehwinkel kontinuierlich zu erfassen ist, relativ kompakt und stabil ausgebildet ist, wobei gleichzeitig auf Schweiß- oder Lötverbindungen verzichtet werden kann. Durch die ganze oder teilweise Ummantelung aus elektrisch nicht leitendem Kunststoff wird die Teileinheit weitgehend resistent auf eine äußere Krafteinwirkung und lässt sich auf einfache Art und Weise durch Einstecken in komplementär ausgebildete Öffnungen von Gehäuseteilen in diese integrieren. Gleichzeitig wird in vorteilhafter Weise der erforderliche Bauraum minimiert und durch die Anordnung der ersten Drossel und der zweiten Drossel eine Entstörung des Systems gewährleistet. Je nach Einsatzzweck lassen sich handelsübliche berührungsfreie, magnetoresistive Drehwinkelsensoren anordnen, so dass die Teileinheit für vielerlei Einsatzzwecke geeignet ist.The object underlying the invention is achieved by a subunit for actuating a rotatably mounted shaft whose current angle of rotation is to be continuously detected, which consists of a grid of metal strips and plug contacts and a first connection which is connected to a first throttle, the is in turn connected to a first motor terminal lug, and a second connection, which is connected to a second choke, which in turn is connected to a second motor terminal lug, and in which the grid is connected at one side in the middle with a non-contact, magnetoresistive rotation angle sensor, wherein the grid, the plug contacts, the first connection, the second connection and the first motor terminal lug and the second motor terminal lug are wholly or partially surrounded by a sheath of electrically non-conductive plastic. The grid of metal strips is the contact grid, which are sold commercially under the name "Leadframe". The plug contacts have several functions. Some of them are used to power an electric motor via the first motor terminal lug and the second motor terminal lug. Other plug contacts serve the power supply of the non-contact, magnetoresistive rotation angle sensor and the individual signal taps. Preferably, six plug contacts are provided for many purposes. Two of them are used to power the electric motor. Two more of them are used to power the non-contact, magnetoresistive rotation angle sensor. Furthermore, two more plug contacts are provided for the signal tap. In this case, two signals are thus detected and tapped by the non-contact, magnetoresistive rotation angle sensor. The grid, the plug contacts, the first connection, the second connection and the first motor connection lug and the second motor connection lug are wholly or partly of one Enclosed surrounded by electrically non-conductive plastic. This means that, for example, portions of the first connection or the second connection or the grid are not surrounded by this conductive plastic. It goes without saying that the plug contacts and the first motor terminal lug and the second motor terminal lug must not be completely surrounded by the electrically non-conductive plastic. It has surprisingly been found that the subunit for actuating a rotatably mounted shaft, whose current angle of rotation is to be continuously detected, is relatively compact and stable, at the same time can be dispensed with welding or solder joints. Due to the whole or partial sheath of electrically non-conductive plastic, the subunit is largely resistant to an external force and can be integrated in a simple manner by plugging into complementary openings of housing parts in this. At the same time, the required space is minimized in an advantageous manner and ensures the suppression of the system by the arrangement of the first throttle and the second throttle. Depending on the application, commercially available, non-contact, magnetoresistive rotation angle sensors can be arranged, so that the subunit is suitable for a wide variety of applications.

Eine bevorzugte Ausgestaltung der Erfindung besteht darin, dass die erste Motoranschlussfahne und die zweite Motoranschlussfahne einen ersten Klemmanschluss beziehungsweise einen zweiten Klemmanschluss aufweisen. Auf diese Weise lässt sich der erforderliche Elektromotor durch einfache Klemmverbindungen mit der Teileinheit verbinden.A preferred embodiment of the invention consists in that the first motor terminal lug and the second motor terminal lug have a first terminal connection or a second terminal connection. In this way, the required electric motor can be connected by simple clamping connections with the subunit.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung sind die erste Motoranschlussfahne und die zweite Motoranschlussfahne lediglich an ihren, der ersten Drossel beziehungsweise der zweiten Drossel abgewandten Enden von einer Ummantelung aus elektrisch nicht leitendem Kunststoff umgeben. Dies ermöglicht eine nicht starre sondern flexible Anordnung der ersten Motoranschlussfahne und der zweiten Motoranschlussfahne, wodurch die Teileinheit in dem jeweiligen Gehäuse durch zusätzliche Klemmkräfte fixiert werden kann. Ferner sind die erforderlichen Toleranzausgleiche auf relativ einfache Weise sicherzustellen.According to a further preferred embodiment of the invention, the first motor terminal lug and the second motor terminal lug are only at their, the first throttle or the second throttle opposite ends surrounded by a sheath of electrically non-conductive plastic. This allows a non-rigid but flexible arrangement of the first motor terminal lug and the second motor terminal lug, whereby the subunit can be fixed in the respective housing by additional clamping forces. Furthermore, the required tolerance compensation in a relatively simple manner to ensure.

Eine weitere bevorzugte Ausgestaltung der Erfindung besteht darin, dass die Breitseiten der ersten Motoranschlussfahne, der zweiten Motoranschlussfahne, des Gitters und der Steckerkontakte parallel zueinander angeordnet sind. Dies bedeutet, dass in der zweidimensionalen Ansicht der Teileinheit die Breitseiten der ersten Motoranschlussfahne, der zweiten Motoranschlussfahne, des Gitters und der Steckerkontakte in einer Ebene liegen. Auf diese Weise erhält die Teileinheit eine nahezu plattenförmige Struktur, so dass der Bauraum optimiert werden kann und die Anordnung in den Gehäusen vereinfacht wird.A further preferred embodiment of the invention is that the broad sides of the first motor terminal lug, the second motor terminal lug, the grid and the plug contacts are arranged parallel to each other. This means that in the two-dimensional view of the subunit, the broad sides of the first motor terminal lug, the second motor terminal lug, the grid and the plug contacts lie in one plane. In this way, the subunit receives a nearly plate-shaped structure, so that the space can be optimized and the arrangement is simplified in the cases.

Nach einer weiteren bevorzugten Ausgestaltung der Erfindung ist das Gitter in einer elektrisch nicht leitenden Trägerplatte angeordnet. Diese kann beispielsweise aus einem elektrisch nicht leitenden Kunststoff bestehen. Zur Herstellung der Teileinheit kann die Kombination aus Gitter und Trägerplatte auch vorgefertigt eingesetzt werden. Im zusammengebauten Zustand der Teileinheit ist dann auch die Trägerplatte ganz oder teilweise von der Ummantelung aus elektrisch nicht leitendem Kunststoff umgeben. Die Anordnung der Trägerplatte hat Vorteile bei der Serienfertigung, da sie das Gitter zusätzlich stabilisiert.According to a further preferred embodiment of the invention, the grid is arranged in an electrically non-conductive support plate. This can for example consist of an electrically non-conductive plastic. To produce the subunit, the combination of grid and carrier plate can also be used prefabricated. In the assembled state of the subunit, the carrier plate is then completely or partially surrounded by the sheath of electrically non-conductive plastic. The arrangement of the carrier plate has advantages in mass production, since it additionally stabilizes the grid.

Gegenstand der Erfindung ist schließlich die Verwendung der Teileinheit als Teileinheit zur Betätigung einer Drosselklappenwelle in einem Drosselklappenstutzen eines Kraftfahrzeuges. In Drosselklappenstutzen ist für die Anordnung elektrischer Bauteile ein nur sehr geringer Bauraum vorhanden. Die Teileinheit zur Betätigung einer drehbar gelagerten Welle, deren aktueller Drehwinkel kontinuierlich zu erfassen ist, lässt sich auf sehr einfache Weise in Drosselklappenstutzen positionieren, was eine Serienfertigung begünstigt.The invention is finally the use of the subunit as a subunit for actuating a throttle shaft in a throttle body of a Motor vehicle. Throttle body for the arrangement of electrical components only a very small space available. The subunit for actuating a rotatably mounted shaft, whose current rotation angle is to be continuously detected, can be positioned in a very simple manner in throttle body, which favors mass production.
