Die Erfindung betrifft ein Wegmesssystem für ein Kolben-Zylindersystem nach dem Oberbegriff des ersten Patentanspruchs und findet insbesondere zur Positionsbestimmung des Kolbens bzw. zur Erfassung des Stellweges bzw. der Stellung der beweglichen Komponente des Kupplungsausrücksystems Anwendung. In Zukunft werden immer mehr Kupplungsgeberzylinder mit einer Wegsensorik ausgestattet. Ein zentraler Punkt bei der Montage eines Geberzylinders mit Sensor spielt dabei die Montage des Sensors auf/in dem Gebergehäuse.The The invention relates to a displacement measuring system for a piston-cylinder system according to the preamble of the first claim and finds in particular to Position determination of the piston or for detection of the travel or the position of the movable component of the clutch release system application. In the future, more and more clutch master cylinder with a displacement sensor fitted. A central point in the assembly of a master cylinder with sensor, the mounting of the sensor on / in the encoder housing plays.
Aus
Weiterhin ist der Abstand des Magnetsensors zum Magnet relativ groß, da das Sensorgehäuse dazwischen liegt. Auch wirkt sich die aufgrund der vielen Bauteile zu verzeichnende große Toleranzkette negativ auf die Genauigkeit des Meßsystems aus.Farther is the distance of the magnetic sensor to the magnet relatively large, because the sensor housing is in between. Also affects due to the many components to record large Tolerance chain negative on the accuracy of the measuring system out.
Durch die Montage der Komponenten zueinander (z. B. durch Schrauben) werden Sensor und Gebergehäuse nur unzureichend genau zueinander positioniert. Dies hat zur Folge, dass eine Kalibrierung des Sensors notwendig wird.By the assembly of the components to each other (eg by screws) are Sensor and encoder housing positioned only insufficiently to each other. This has the consequence that a calibration of the sensor is necessary becomes.
Aufgabe der Erfindung ist es, ein Wegmesssystem für Kupplungsausrücksysteme zu entwickeln, welches für die Befestigung des Sensors einen geringen Bauraum und eine minimale Anzahl von Komponenten benötigt. Weiterhin soll die Zuverlässigkeit und die Genauigkeit des Systems erhöht werden.task The invention is a Wegmesssystem for Kupplungsausrücksysteme to develop, which for the attachment of the sensor a small space and a minimum number of components needed. Furthermore, the reliability and the accuracy of the system can be increased.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des ersten Patentanspruchs gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.These The object is achieved by the characterizing features of the first patent claim solved. Advantageous embodiments emerge from the subclaims.
Das Wegmesssystem für ein Kolben-Zylindersystem ist insbesondere in Form eines Kupplungsgeberzylinders ausgebildet, mit einem einer beweglichen Komponente zuordenbaren Sensorelement sowie mit einem eine Sensorelektronik aufweisendem Sensorsystem, welches an einer feststehenden Komponente insbesondere an einem Gehäuse des Kolben-Zylindersystems angeordnet ist, wobei das Sensorsystem mit dem Sensorelement in Wirkverbindung steht und erfindungsgemäß das Gehäuse des Kolben-Zylindersystems eine Aussparung aufweist, in welche die auf einem Träger vorzugsweise einer Platine oder einem Stanzgitter integrierte Sensorelektronik des Sensorsystems eingeschoben werden kann.The Distance measuring system for a piston-cylinder system is particular formed in the form of a clutch master cylinder, with a one movable component assignable sensor element and with a a sensor electronics exhibiting sensor system, which at a fixed component, in particular on a housing of the Piston-cylinder system is arranged, wherein the sensor system with the sensor element is in operative connection and according to the invention Housing of the piston-cylinder system has a recess, in which the on a support preferably a circuit board or a punched grid integrated sensor electronics of the sensor system can be inserted.
Im Folgenden wird der Träger zur Vereinfachung nur noch als Platine bezeichnet.in the Subsequently, the carrier is for simplicity only as Board designates.
Dafür weist das Gehäuse an seiner Innenseite Laufschienen auf, in welche die Platine eingeschoben wird.Therefore the housing has rails on its inside, in which the board is inserted.
Die Fixierung der Platine im Gehäuse kann z. B. mittels eines oder mehrerer Clipelemente erfolgen, die z. B. in Form von Schnapphaken ausgebildet sein können und die bei Erreichen der Montageendposition in entsprechende Rastöffnungen des Gehäuses eingreifen.The Fixation of the board in the housing can z. B. by means of a or more clip elements take place, the z. B. in the form of snap hooks may be formed and when reaching the Montageendposition engage in corresponding latching openings of the housing.
Die Fixierung der Platine im Gehäuse kann alternativ auch mittels einer Kunststoffverschweißung oder Verklebung erfolgen.The Fixation of the board in the housing can alternatively by means of a plastic welding or gluing done.
Die Laufschienen dienen gleichzeitig zur Ausrichtung des Sensors. Je nach eingesetztem Sensorprinzip wirkt sich entweder die Positioniergenauigkeit in Bewegungsrichtung (Sensorausrichtung tangential am Umfang des Gehäuses) oder senkrecht zur Bewegungsrichtung auf die Genauigkeit des Messsignals stärker aus. Deshalb ist je nach Wahl des Sensorprinzips die Anordnung des Sensors zum Gehäuse zu wählen. Gezeigt ist im Folgenden die Anordnung des Sensors senkrecht zur Bewegungsrichtung. Analog verhält es sich bei der Anordnung des Sensors in Bewegungsrichtung. Wenn in Bewegungsrichtung des Kolbens – also in Sensierrichtung zur Lagefeststellung – eine höhere Genauigkeit gefordert wird, als in die Rich tung senkrecht zur Bewegungsrichtung des Kolbens, erfolgt die Anbringung der Laufschienen senkrecht zur Bewegungsrichtung des Kolbens.The Tracks also serve to align the sensor. ever After inserted sensor principle affects either the positioning accuracy in the direction of movement (sensor orientation tangential to the circumference of the Housing) or perpendicular to the direction of movement on the Accuracy of the measurement signal stronger. That's why ever at the option of the sensor principle, the arrangement of the sensor to the housing to choose. Shown below is the arrangement of the sensor perpendicular to the direction of movement. The same is true in the arrangement of the sensor in the direction of movement. When in the direction of movement of the piston - ie in Sensierrichtung for detecting the position - a higher accuracy is required than in the rich direction perpendicular to the direction of movement of the piston, the attachment takes place the rails perpendicular to the direction of movement of the piston.
Um eine genügende Lagefixierung der Platine zu gewährleisten können in die Laufschienen in Platineneinschubrichtung die Fixierung der Platine gewährleistende Quetschrippen oder auch flexible Spannelemente integriert sein.In order to ensure a sufficient position fixation of the board can in the rails in board insertion direction, the fixation of the board Ensuring Quetschrippen or flexible clamping elements integrated.
An die Platine schließt sich ein Steckbereich für den Anschluss eines Steckers an die Platine an.At the board joins a plug-in area for the connection of a plug to the board.
Zwischen dem Gehäuse und dem Steckbereich sollte eine die Dichtheit gewährleistende Dichtung integriert sein, die gegenüber den Umwelteinflüssen abdichtet und die z. B. in Form einer Feststoffdichtung ausgebildet sein kann. Es ist alternativ auch möglich, den Steckbereich mit dem Gehäuse unlösbar zu verbinden. Dies kann z. B. stoffschlüssig mittels Laserschweißen oder Kleben realisiert werden.Between the housing and the plug-in area should have a tightness Ensuring gasket be integrated opposite seals the environmental influences and the z. B. in the form of a Solid seal can be formed. It is alternative too possible, the plug-in area with the housing insoluble connect to. This can be z. B. cohesively by laser welding or gluing.
Dazu ist es auch möglich, den Steckbereich und das Gehäuse vollständig oder teilweise aus transparentem Kunststoff zu fertigen.To It is also possible the plug-in area and the housing completely or partially made of transparent plastic to manufacture.
Die im Gehäuse vorhandene Aussparung wird bevorzugt durch einteilige Fertigung des Gehäuses aus Kunststoff durch Spritzgießen hergestellt.The in the housing existing recess is preferably by one-piece Production of plastic housing by injection molding produced.
Alternativ kann die Aussparung auch mit dem Gehäuse einteilig aus metallischem Werkstoff im Druckgussverfahren hergestellt sein.alternative The recess can also be made in one piece with the housing metallic material be produced by die casting.
Mit der erfindungsgemäßen Lösung wird eine überraschend einfache, kostengünstige und Platz sparende Lösung der Integration der Sensorelektronik geschaffen, insbesondere da kein separates Sensorgehäuse mehr erforderlich ist, welches erst aufwendig am Gehäuse befestigt werden muss.With the solution according to the invention becomes a surprising simple, cost effective and space saving solution the integration of sensor electronics created, especially there no separate sensor housing is required, which only consuming must be attached to the housing.
Es ist erstmalig möglich, einen von Sensorlieferant vorgefertigten Sensor bzw. eine Sensorplatine sehr einfach zu montieren, da dieser nur im Einschub des Gehäuses platziert werden muss. Die Positionierung übernehmen die Führungsschienen mit ggf. Quetschrippen oder Spannelementen und die Fixierung die Schnapphaken.It is possible for the first time, a prefabricated by sensor supplier Sensor or a sensor board very easy to install, since this only in the slot of the housing must be placed. The Positioning take over the guide rails with possibly crush ribs or clamping elements and fixing the Snap hook.
