Die Montage der Messeinrichtung soll ohne großen Aufwand möglich sein.The Object of the present invention is therefore a Radsatzlagergehäuse with a measuring device for detecting mechanical defects in wheelsets of To equip rail vehicles, no intervention in the construction of conventional wheelset bearing housing may be necessary should and sufficient space for the protective device available to be asked. The installation of the measuring device should be without huge Effort possible be.
Zur Lösung dieser Aufgabe dient eine Messeinrichtung zur kontinuierlichen Erfassung der Betriebsparameter, insbesondere mechanischer Defekte an Radsätzen von Schienenfahrzeugen mit einem zylindrischen Sensorgehäuse und mindestens einem innerhalb des Sensorgehäuses angeordneten Sensor. Das Sensorgehäuse weist eine Durchgangsbohrung in axialer Richtung auf und kann auf einem Schraubendeckel bzw. kurz Deckel eines Radsatzlagergehäuses befestigt werden. Zur Befestigung dient dabei eine durch die Bohrung des Sensorgehäuses und durch eine vorhandene Schraubendeckelbohrung im Deckel des Radsatzlagergehäuses in das Radsatzlagergehäuse einschraubbare Deckelschraube.to solution This task is served by a measuring device for continuous detection the operating parameters, in particular mechanical defects in wheelsets of Rail vehicles with a cylindrical sensor housing and at least one sensor disposed within the sensor housing. The sensor housing has a through hole in the axial direction and can on attached to a screw cap or short cover of a wheelset bearing housing become. For attachment serves a through the bore of the sensor housing and through an existing screw cap hole in the cover of the wheelset bearing housing in the wheelset bearing housing screw-in cover screw.
Ein Vorteil der erfindungsgemäßen Lösung ist in der sehr einfachen Realisierung zu sehen. Zur Anbringung der Messeinrichtung müssen keine Veränderungen am vorhandenen Radsatzlagergehäuse vorgenommen werden, da die bereits vorhandenen Bohrungen im Schraubendeckel und im Radsatz lagergehäuse, dort vorzugsweise mit entsprechendem Innengewinde zur Verschraubung mit der Deckelschraube, für die Ankopplung des Sensors verwendet werden. Ein entsprechend hohes Anzugsmoment der zur Befestigung verwendeten Deckelschraube ermöglicht eine gute Ankopplung des Sensorgehäuses und damit der Sensoren an das Radsatzlagergehäuse.An advantage of the solution according to the invention can be seen in the very simple realization. To attach the measuring device no changes must be made to the existing wheelset bearing housing, since the existing holes in the screw cap and in the wheelset bearing housing, there preferably with appropriate internal thread for screwing with the cover screw, are used for the coupling of the sensor. A correspondingly high tightening torque of the cover screw used for fastening allows a good coupling of the sensor housing and thus the sensors to the Radsatzlagerge housing.
Das Sensorgehäuse kann so dimensioniert werden, dass es für unterschiedlich ausgestaltete Sensoren ausreichend Platz bietet. Durch die Anordnung der Sensoren innerhalb des Sensorgehäuses sind die Sensoren vor schädlichen Umwelteinflüssen geschützt und verschmutzen daher auch nicht so schnell. Die Sensorgehäuse können in einem vorgelagerten Fertigungsschritt mit den gewünschten Sensoren konfektioniert werden, so dass sich Justagearbeiten währende des Anbaus des Sensorgehäuses am Radsatzlager erübrigen.The sensor housing can be sized to suit different sized sensors offers enough space. Due to the arrangement of the sensors within of the sensor housing are the sensors from harmful Protected against environmental influences and so do not pollute so fast. The sensor housings can be in an upstream production step with the desired Sensors are assembled, so that adjustment work throughout the Mounting the sensor housing on the Needless to say wheelset bearings.
Nach einer vorteilhaften Ausführungsform besteht das Sensorgehäuse aus einem Material mit einer guten Wärmeleitung. Auf diese Weise ist ein guter Wärmeübergang vom Radsatzlagergehäuse auf das Sensorgehäuse und die innerhalb des Sensorgehäuses angeordneten Sensoren gewährleistet. Besonders zweckmäßig ist es, wenn das Sensorgehäuse außerdem noch mit einer zusätzlichen Außenisolierung versehen ist. Dadurch können durch die Umgebungsbedingungen hervorgerufene Messfehler reduziert werden.To an advantageous embodiment the sensor housing made of a material with good heat conduction. In this way is a good heat transfer from the wheelset bearing housing the sensor housing and inside the sensor housing arranged sensors ensured. Especially is appropriate it if the sensor housing Furthermore still with an additional external insulation is provided. Thereby can reduced by the environmental conditions caused measurement errors become.
Eine weitere zweckmäßige Ausführungsform verwendet zur Befestigung des Sensorgehäuses eine Deckelschraube die länger als die weiteren zur Befestigung des Deckels dienenden Deckelschrauben ist. Die zusätzlich benötigte Länge richtet sich dabei nach der jeweiligen axialen Länge des verwendeten Sensorgehäuses. Mit einer derart ausgeführten Deckelschraube kann eine sichere Schraubverbindung zwischen Sensorgehäuse, Deckel und Radsatzlagergehäuse hergestellt werden, da die Deckelschraube entsprechend tief ins Radsatzlagergehäuse eingeschraubt werden kann. Das Radsatzlagergehäuse weist dazu vorzugsweise eine entsprechende Bohrung mit Innenge winde auf.A used further expedient embodiment for mounting the sensor housing a Cover screw the longer as the other lid screws used to attach the lid is. The additional needed Length this depends on the respective axial length of the sensor housing used. With such a running Cover screw can be a secure screw connection between the sensor housing, cover and wheelset bearing housing be prepared because the cover screw corresponding deep into the axle-box can be screwed. The wheelset bearing housing preferably has for this purpose a corresponding hole with Innenge thread on.
Weiterhin ist es vorteilhaft, wenn im Sensorgehäuse ein Temperatursensor angeordnet ist. Mittels Temperatursensor kann eine unzulässige Erwärmung des Radsatzlagers rechtzeitig ermittelt werden.Farther it is advantageous if arranged in the sensor housing, a temperature sensor is. By means of a temperature sensor, an inadmissible heating of the wheelset bearing in time be determined.
Nach einer vorteilhaften Ausführungsform kann sich im Sensorgehäuse ein Beschleunigungssensor befinden. Durch Beschleunigungssensoren können außergewöhnliche Erschütterungen am Radsatz erfasst werden. Solche Erschütterungen können beispielsweise bei Verschleiß oder Defekten der Radsatzlager auftreten.To an advantageous embodiment can in the sensor housing an acceleration sensor are located. Through acceleration sensors can be extraordinary shocks be detected on the wheelset. Such shocks can, for example, wear or defects the wheelset bearing occur.
Bei einer weiteren günstigen Ausführungsform ist die Messeinrichtung mit einer Auswerteeinrichtung zur Auswertung der Sensordaten gekoppelt. Mittels Auswerteeinrichtung können die ermittelten Sensordaten mit vorgegebenen Grenzwerten verglichen werden. In diesem Zusammenhang hat es sich als zweckmäßig erwiesen, wenn die Auswerteeinrichtung mit einer Steuereinrichtung zum Erzeugen von Alarmsignalen gekoppelt ist. Im Fall von durch die Auswerteeinrichtung ermittelten Grenzwertüberschreitungen wird durch die Steuereinrichtung ein Alarm ausgelöst. Das Bedienpersonal kann nun entsprechende Schutzmaßnahmen ergreifen, um eine drohende Havarie zu vermeiden.at another cheap embodiment is the measuring device with an evaluation device for evaluation coupled to the sensor data. By means of evaluation, the determined sensor data compared with predetermined limits become. In this context, it has proven to be expedient if the evaluation device with a control device for generating Alarm signals is coupled. In the case of by the evaluation determined limit value exceedances an alarm is triggered by the control device. The Operating personnel can now take appropriate protective measures to an impending To avoid damage.
