Abstract
Description
Die Erfindung betrifft einen Getriebe-Nocken-Endschalter. The invention relates to a transmission cam limit switch.
Getriebe-Nocken-Endschalter umfassen typisch eine Eingangswelle, die mit einer korrespondierenden Antriebswelle eines zu überwachenden Antriebs drehfest koppelbar ist, ein mit der Eingangswelle gekoppeltes Getriebe, eine oder mehrere mit einem Getriebeabtrieb des Getriebes gekoppelte Nockenscheibe(n) und mittels der Nockenscheibe(n) mechanisch betätigte Schaltkontakte, deren Schaltzustand von einer Winkelstellung der Eingangswelle abhängt. Die Winkelstellung der Eingangswelle wird folglich mittels der Schaltzustände der Schaltkontakte kodiert.Gear cam limit switches typically comprise an input shaft rotatably coupled to a corresponding drive shaft of a drive to be monitored, a transmission coupled to the input shaft, one or more cam discs coupled to a transmission output of the transmission, and by means of the cam disc (s). mechanically actuated switch contacts whose switching state depends on an angular position of the input shaft. The angular position of the input shaft is thus coded by means of the switching states of the switching contacts.
Der Erfindung liegt die Aufgabe zugrunde, einen Getriebe-Nocken-Endschalter der eingangs genannten Art dahingehend weiterzubilden, dass ein möglichst sicherer Betrieb des Getriebe-Nocken-Endschalters ermöglicht wird.The invention has the object of providing a transmission cam limit switch of the type mentioned in such a way that the safest possible operation of the gear cam limit switch is made possible.
Die Erfindung löst diese Aufgabe durch einen Getriebe-Nocken-Endschalter nach Anspruch 1.The invention solves this problem by a gear cam limit switch according to
Bevorzugte Ausgestaltungen sind Gegenstand der Unteransprüche, deren Wortlaut hiermit durch Bezugnahme zum Inhalt der Beschreibung gemacht wird.Preferred embodiments are the subject of the subclaims, the wording of which is hereby incorporated by reference into the content of the description.
Der Getriebe-Nocken-Endschalter umfasst herkömmlich eine Eingangswelle, die mit einer korrespondierenden Antriebswelle eines Antriebs drehfest mechanisch koppelbar ist, ein mit der Eingangswelle gekoppeltes erstes Getriebe, mindestens eine mit einem Getriebeabtrieb des ersten Getriebes gekoppelte Nockenscheibe und mindestens einen mittels der Nockenscheibe mechanisch betätigten Schaltkontakt, dessen Schaltzustand von einer Winkelstellung der Eingangswelle abhängt. Insoweit sei auch auf die Spezifikation herkömmlicher Getriebe-Nocken-Endschalter verwiesen, um unnötige Wiederholungen zu vermeiden. The gear-cam limit switch conventionally comprises an input shaft which is mechanically non-rotatably coupled to a corresponding drive shaft of a drive, coupled to the input shaft first gear, at least one coupled to a transmission output of the first gear cam and at least one mechanically actuated by the cam switch contact whose switching state depends on an angular position of the input shaft. In that regard, reference is also made to the specification of conventional gear-cam limit switch to avoid unnecessary repetition.
Erfindungsgemäß ist eine, insbesondere elektrische bzw. elektronische, Winkelmesseinrichtung vorgesehen, die dazu ausgebildet ist, eine Winkelstellung der Eingangswelle unabhängig vom und zusätzlich zum Schaltzustand des mindestens einen Schaltkontakts zu messen. Die Winkelmesseinrichtung ist insbesondere dazu ausgebildet, die Winkelstellung redundant zu der und basierend auf einem anderen Messprinzip als die schaltzustandsbasierte Winkelmessung bzw. Winkelkodierung zu messen. D. h. der erfindungsgemäße Getriebe-Nocken-Endschalter ist um eine redundante und diversitäre Winkelmesseinrichtung ergänzt, so dass ein herkömmlicher Getriebe-Nocken-Endschalter dahingehend weitergebildet wird, dass eine redundante Erfassung der Winkelstellung der Eingangswelle möglich ist und über die Schaltzustände der Schaltkontakte hinaus weitere physikalische Größen, wie beispielsweise eine Winkelgeschwindigkeit der Eingangswelle und Zwischenstellungen der Eingangswelle, erfassbar sind.According to the invention, an angle measuring device, in particular electrical or electronic, is provided, which is designed to measure an angular position of the input shaft independently of and in addition to the switching state of the at least one switching contact. The angle measuring device is in particular designed to measure the angular position redundantly to and based on a different measuring principle than the switching state-based angle measurement or angle coding. Ie. the gear-cam limit switch according to the invention is supplemented by a redundant and diverse angle measuring device, so that a conventional gear cam limit switch is developed to the effect that a redundant detection of the angular position of the input shaft is possible and on the switching states of the switch contacts addition physical variables, such as an angular velocity of the input shaft and intermediate positions of the input shaft, are detectable.
In einer Weiterbildung weist die Winkelmesseinrichtung optische Sensoren zur Winkelerfassung auf, beispielsweise Lichtschranken etc.In one development, the angle measuring device has optical sensors for angle detection, for example light barriers, etc.
In einer Weiterbildung weist die Winkelmesseinrichtung magnetische Sensoren zur Winkelerfassung auf, beispielsweise AMR(anisotrope magnetoresistance)-, GMR(giant magnetoresistance)- oder Hall-Sensoren.In one development, the angle measuring device has magnetic sensors for angle detection, for example AMR (anisotropic magnetoresistance), GMR (giant magnetoresistance) or Hall sensors.
In einer Weiterbildung ist ein zweites Getriebe vorgesehen, das mit der Eingangswelle gekoppelt ist, wobei die Winkelmesseinrichtung mit einem Getriebeabtrieb des zweiten Getriebes gekoppelt ist.In a development, a second transmission is provided, which is coupled to the input shaft, wherein the angle measuring device is coupled to a transmission output of the second transmission.
In einer Weiterbildung ist ein Gehäuse vorgesehen, in welches das erste Getriebe, das zweite Getriebe, die Eingangswelle, die mindestens eine Nockenscheibe, der mindestens eine Schaltkontakt und /oder die Winkelmesseinrichtung integriert sind.In a further development, a housing is provided in which the first gear, the second gear, the input shaft, the at least one cam, the at least one switching contact and / or the angle measuring device are integrated.
Die Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung beschrieben, die bevorzugte Ausführungsformen der Erfindung darstellt. Hierbei zeigt schematisch:The invention will now be described with reference to the drawing, which shows preferred embodiments of the invention. This shows schematically:

Aufgrund der diversitären Redundanz nimmt die Betriebssicherheit deutlich zu, da Fehler aufgrund widersprüchlich erfasster Winkelstellungen einfach detektierbar sind, worauf ein sicherer Betriebszustand hergestellt werden kann.Due to the diverse redundancy, the reliability increases significantly, since errors due to contradictory detected angular positions are easily detectable, whereupon a safe operating condition can be established.
