Abstract

The invention relates to a device for displaying the derailment state of at least one wheel of a rail-guided, particularly a rail-mounted, vehicle, e.g. a locomotive, wherein a rail (1) is detachably connected to a base, e.g., a wooden tie (3) or a concrete slab, by means of fixing elements such as screws (4) or clamps, for example. A sensor (5) for detecting a derailed wheel is disposed alongside and beneath a top edge of the rail, wherein the top edges of the rail define the rail plane (2). According to the invention, a cover (6) is provided for the at least one sensor (5), upwardly covering the one or more fixing elements (4) essentially to protect the latter against the direct effects of the derailed wheel, whereby the derailed wheel is covered at least partially in the direction of the rail. The sensor (5) incorporates a pressure, force, displacement and/or acceleration sensor.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Anzeigen von zumindest einem entgleisten Rad eines schienengeleiteten, insbesondere schienengeführten, Fahrzeuges, z. B. Triebfahrzeuges, wobei eine Schiene mit einem Untergrund, z. B. Holzschwelle, Betonplatte, über Befestigungsmittel lösbar verbunden ist.The invention relates to a device for displaying at least one derailed wheel of a rail-guided, in particular rail-guided, vehicle, for. B. traction vehicle, with a rail with a background, z. B. wooden threshold, concrete slab, is releasably connected via fastening means.

Obwohl Entgleisungen von schienengeführten Fahrzeugen außerordentlich selten auftreten, ist der dabei verursachte Schaden an der Infrastruktur und auch an dem rollenden Material von besonderer Bedeutung. Es werden hierbei längere Strecken des Fahrweges zerstört und mit der Entgleisung eines Fahrzeuges eines Zuges wird kurzfristig die Entgleisung weiterer Fahrzeuge, insbesondere des gesamten Zuges, verursacht.Although derailment of rail-guided vehicles is extremely rare, damage to infrastructure and rolling stock is of particular importance. In this case, longer distances of the track are destroyed and with the derailment of a vehicle of a train, the derailment of other vehicles, especially the entire train is caused in the short term.

Durch die Liberalisierung auch auf dem Gebiet des schienengeführten Verkehrs wird der Einsatz von unterschiedlichsten Fahrzeugen als auch Wagen, insbesondere Güterwagen, ermöglicht. Die Bahnstrecken wurden ursprünglich für geringere Geschwindigkeiten als jetzt vorgesehen errichtet und mussten für dieselben ertüchtigt werden. Eine weitere Erschwernis besteht darin, dass das rollende Material für niedrigere Geschwindigkeiten konstruiert wurde als zurzeit eingesetzt.The liberalization of rail-based transport also makes it possible to use a wide variety of vehicles as well as wagons, in particular freight wagons. The railroad lines were originally built for lower speeds than now planned and had to be upgraded for the same. Another complication is that the rolling stock was designed for lower speeds than currently used.

Obwohl die oben angeführten Bedingungen berücksichtigt werden, können Entgleisungen aufgrund des Schienenweges als auch des rollenden Materials nicht ausgeschlossen werden.Although the above conditions are taken into account, derailments due to the rail track as well as the rolling stock can not be excluded.

Der vorliegenden Erfindung ist zur Aufgabe gesetzt, das Entgleisen zumindest eines Rades eines schienengeleiteten Verkehrs anzuzeigen. Derartige Vorrichtungen sind in Anbetracht der besonderen Bedeutung des Entgleisens vielfach bekannt. Ein entgleisendes Fahrzeug, so sich nicht ein Rad von demselben abgetrennt hat, weist ein Rad zwischen den Schienen und eines außerhalb der Schienen auf. Schienen weisen in der Regel beidseitig zu denselben Befestigungsmittel auf, um ihre Lage zu fixieren. Diese Befestigungsmittel müssen eine Fixierung der Schienen quer zur Längsrichtung, also innerhalb der Gleisebene, exakt erlauben, wohingegen normal zu derselben ein Einfedern des Gleises um 1 mm bis 2 mm ermöglicht sein soll.The object of the present invention is to indicate the derailment of at least one wheel of a rail-guided traffic. Such devices are considered The special significance of derailing widely known. A derailing vehicle, unless a wheel has separated from it, has a wheel between the rails and one outside the rails. Rails generally have on both sides to the same fasteners to fix their position. These fasteners must allow a fixation of the rails transversely to the longitudinal direction, ie within the track level, exactly, whereas normal to the same a compression of the track should be made possible by 1 mm to 2 mm.

Bei Entgleisung von Schienenfahrzeugen ist es von besonderer Bedeutung, dass dieselbe möglichst vorzeitig erfasst wird. Bei Entgleisung eines Schienenfahrzeuges läuft dasselbe, insbesondere das Rad, aber auch die Räder desselben, entlang der Schiene. Hierbei setzt dasselbe auf die Schienenbefestigungsmittel, z. B. Schrauben, Schienenklammern od. dgl., auf. Die bislang bekannten Vorrichtungen zum Anzeigen eines entgleisten Zuges sind lediglich geeignet, die Entgleisung dann anzuzeigen, wenn das Schienenrad jenseits der Befestigungsmittel zwischen den Schienen läuft. Damit ist eine wesentliche Verzögerung der Anzeige von Entgleisungen gegeben, so dass eine größere Zerstörung des Gleises und des rollenden Materials als auch Gefährdung der beförderten Personen gegeben ist.In the case of derailment of rolling stock, it is of particular importance that it is detected as early as possible. When derailment of a rail vehicle the same, in particular the wheel, but also the wheels of the same, along the rail. In this case, it relies on the rail fastening means, for. As screws, rail clips od. Like., On. The hitherto known devices for displaying a derailed train are only suitable for displaying the derailment when the rail wheel passes between the rails beyond the attachment means. This is a significant delay in the display of derailment is given, so that a greater destruction of the track and the rolling stock as well as endangering the promoted persons is given.

Die DE 195 43 189 A1 hat eine Vorrichtung zum Anzeigen eines entgleisten schienengeführten Fahrzeuges zum Gegenstand. Das schienengeleitete Fahrzeug ist ein Förderwagen, der über eine integrierte Kettenbahn transportiert wird. Beim Entgleisen eines Förderwagens wird ein luftgefüllter Schlauch, der unterhalb der Schwellen angeordnet ist, beaufschlagt. Dieser Schlauch wird von einer Schiene zur anderen Schiene auf einer Schwelle geführt und von dieser erneut unterhalb der Schiene zu einer Entgleisungsüberwachungseinrichtung geführt und mit dieser verbunden. Am anderen Ende ist der Schlauch über einen Stopfen verschlossen. Der Schlauch weist in seinem Bereich der Überleitung von einer zur anderen Schiene auf der Schwelle eine Abdeckung aus einem U-Eisen auf. Oberhalb des Luftschlauches und des U-Eisens ist eine zwischen den Schienen sich erstreckende Bandgummiabdeckung vorgesehen. Wie diese Vorrichtung arbeitet, kann nicht entnommen werden. Es wird lediglich ausgeführt, dass ein entgleister Förderwagen über die Bandgummiabdeckung auf die U-Eisen-Auflage aufgeschoben wird, womit der Luftschlauch zusammengequetscht und im Differenzdruckauswertegerät ein Differenzdruck aufgebaut wird.The DE 195 43 189 A1 has a device for displaying a derailed rail-guided vehicle to the object. The rail-guided vehicle is a trolley, which is transported via an integrated chain conveyor. When derailment of a trolley, an air-filled hose, which is arranged below the threshold, acted upon. This hose is guided from one rail to the other rail on a threshold and led by this again below the rail to a derailment monitoring device and connected thereto. At the other end, the hose is over one Plug closed. The tube has in its region of the transition from one to the other rail on the threshold a cover of a U-iron. Above the air hose and the U-iron, a band rubber cover extending between the rails is provided. How this device works, can not be removed. It is merely stated that a degassed trolley is pushed over the band rubber cover on the U-iron support, which squeezes the air hose together and a differential pressure is built up in the differential pressure gauge.

In der US 6 412 332 B1 wird eine Vorrichtung beschrieben, mit welcher von der Unterseite eines Schienenfahrzeuges nach unten herabhängende Teile detektiert werden sollen. Hierzu sind Detektoren vorgesehen, die quer zur Schienenlängsrichtung zwischen zwei Schwellen angeordnet sind. Diese Detektoren weisen Abdeckungen auf, die aus begreiflichen Gründen bis zur vertikalen Höhe der Schienenkopfunterkante geführt sind. Würde an dieser Vorrichtung ein bereits entgleister Zug vorbeifahren, so würden die Schienenräder noch höher angehoben und eine Entgleisung weiterhin gefördert werden. Eine Abdeckung der Schienenbefestigungsmittel liegt nicht vor.In the US Pat. No. 6,412,332 B1 a device is described with which from the bottom of a rail vehicle down-hanging parts to be detected. For this purpose, detectors are provided which are arranged transversely to the rail longitudinal direction between two thresholds. These detectors have covers, which are out of understandable reasons up to the vertical height of the rail head lower edge. If an already derailed train would pass by this device, the rail wheels would be raised even higher and a derailment would continue to be promoted. A cover of the rail fasteners is not available.

In der US 6 564 467 B1 wird eine Vorrichtung zur Bestimmung der Unrundheit eines Wagenrädes beschrieben. Dabei wird davon ausgegangen, dass die Unrundheit lediglich bei der Lauffläche, nicht jedoch beim Flansch des Schienenrades vorliegt. Zu dieser Bestimmung ist unmittelbar neben dem Schienenkopf ein mechanischer Detektor vorgesehen, der eine obere im Querschnitt U-förmige Abdeckung aufweist, welche über eine Feder in Ausgangslage gehalten wird. Bei Beaufschlagung dieser oberen Abdeckung wird ein Umsetzer mit einer schrägen Fläche in Kooperation gebracht, wodurch die Einfederung bestimmt werden kann. Diese Vorrichtung ist aufgrund der konstruktiven Ausbildung nicht geeignet, einen entgleisenden Zug anzuzeigen, da bei einer Entgleisung dieselbe aufgrund der einwirkenden Kräfte vollkommen zerstört würde. Der Unterschied bei unrunden Rädern gegenüber runden Rädern ist relativ geringfügig, so dass auch nur geringe Kräfte auftreten, wohingegen bei einer Entgleisung wesentlich höhere Kräfte auftreten.In the US Pat. No. 6,564,467 B1 a device for determining the out-of-roundness of a carriage wheel is described. It is assumed that the out-of-roundness is present only at the tread, but not at the flange of the rail wheel. For this purpose, a mechanical detector is provided immediately adjacent to the rail head, which has an upper cross-sectionally U-shaped cover, which is held by a spring in the starting position. Upon application of this top cover, a translator with an inclined surface is brought into cooperation, whereby the deflection can be determined. This device is not suitable due to the structural design to indicate a derailed train, since at derailment would be completely destroyed by the forces acting on it. The difference in non-round wheels compared to round wheels is relatively small, so that even small forces occur, whereas significantly higher forces occur in a derailment.

In der US 4 895 324 A wird eine transportable wieder verwendbare Vorrichtung zur Bestimmung der Entgleisung beschrieben, die keine Abdeckung aufweist.In the US Pat. No. 4,895,324 there is described a portable reusable derailment device which has no cover.

In der AT 410 530 B , von welchem Stand der Technik die vorliegende Erfindung ausgeht, ist ein Entgleisungswarnsystem für Tunnelstrecken beschrieben. Als Fühler ist ein elektrischer Leiter oder auch ein Glasfaserleiter für Licht vorgesehen, die beim Entgleisen durchtrennt werden. Derartige Fühler können erst dann wirksam werden, wenn diese zwischen den Befestigungsmitteln nicht jedoch auf diesen oder zwischen den Schienen und diesen angeordnet sind. Damit tritt ein wesentlicher Nachteil, u. zw., dass ein großer Zeitbereich verstreicht, bis die Entgleisung angezeigt werden kann, auf, nachdem dieselbe stattgefunden hat.In the AT 410 530 B From which state of the art the present invention proceeds, a derailment warning system for tunnels is described. As a sensor, an electrical conductor or an optical fiber for light is provided, which are severed during derailment. Such sensors can only be effective if they are not arranged between the fastening means on this or between the rails and these. This is a major disadvantage, u. that a large period of time elapses until the derailment can be signaled, after it has occurred.

Die erfindungsgemäße Vorrichtung zum Anzeigen von zumindest einem entgleisten Rad eines schienengeleiteten, insbesondere schienengeführten, Fahrzeuges, z. B. Triebfahrzeuges, wobei eine Schiene mit einem Untergrund, z. B. Holzschwelle, Betonplatte, über Befestigungsmittel, z. B. Schrauben, Klammern, lösbar verbunden ist, und unterhalb einer Schienenoberkante neben einer Schiene ein Fühler für ein entgleistes Rad angeordnet ist, und durch die Schienenoberkanten eine Gleisebene definiert ist, besteht im Wesentlichen darin, dass eine Abdeckung für den zumindest einen Fühler vorgesehen ist, die nach oben das/die Befestigungsmittel zumindest im Wesentlichen vor dem unmittelbaren Einwirken des entgleisten Rades und dasselbe in Richtung zur Schiene zumindest teilweise abdeckt, und der Fühler einen Druck-, Kraft-, Weg- und/oder Beschleunigungsfühler aufweist.The inventive device for displaying at least one derailed wheel of a rail-guided, in particular rail-guided, vehicle, for. B. traction vehicle, with a rail with a background, z. B. wooden threshold, concrete slab, via fasteners, z. As screws, brackets, is detachably connected, and below a rail top next to a rail a sensor for a derailed wheel is arranged, and by the rail top edges a track level is defined, essentially consists in that a cover for the at least one sensor is provided which at least substantially covers the attachment means at least substantially before the direct action of the derailed wheel and the same towards the rail, and the sensor has a pressure, force, displacement and / or acceleration sensor.

Die erfindungsgemäße Vorrichtung ist sowohl für einen Schotteroberbau als auch schotterlosen Oberbau geeignet, wobei für die Schienen lösbare Befestigungsmittel vorgesehen sind, die in der Regel oberhalb des Schienenfußes angeordnet werden. Durch die in der Regel zwei Schienen und der oberen Laufflächen der Schienenköpfe wird die Gleisebene definiert, an welcher die Schienenräder laufen. Bei Verlassen derselben durch die Räder kann und ist in der Regel ein Entgleisen des schienengeführten Fahrzeuges bedingt. Die Räder des Fahrzeuges laufen bei einer Entgleisung vorerst entlang der Schienen. Dies ist vor allen durch die Kreiselwirkung der Räder bedingt, da dieselben in ihrer Rotationsebene verbleiben, so nicht größere Kräfte einwirken. Das erste Anzeichen der Entgleisung ist somit, dass die Räder zwischen den Schienen und den Befestigungsmitteln bzw. auf denselben laufen. Es ist somit wesentlich, dass diese erste Stufe der Entgleisung bereits angezeigt werden kann. Gemäß der vorliegenden Erfindung ist eine Abdeckung für den zumindest einen Fühler vorgesehen, wobei die Abdeckung nach oben das/die Befestigungsmittel zumindest im Wesentlichen vor dem Einwirken des entgleisten Rades und dasselbe in Richtung zur Schiene zumindest teilweise abdeckt und der Fühler einen Druck-, Kraft-, Weg- und/oder Beschleunigungsaufnehmer aufweist.The device according to the invention is suitable for both a ballast track and ballastless superstructure, wherein releasable fastening means are provided for the rails, which are usually arranged above the rail foot. By usually two rails and the upper treads of the rail heads, the track level is defined at which run the rail wheels. When leaving the same through the wheels can and is usually a derailment of the rail-guided vehicle conditional. The wheels of the vehicle run at a derailment for the time being along the rails. This is due in particular to the gyro effect of the wheels, since they remain in their plane of rotation, so that no greater forces act. The first sign of the derailment is thus that the wheels run between or on the rails and fasteners. It is therefore essential that this first stage of the derailment can already be displayed. According to the present invention, a cover is provided for the at least one sensor, wherein the cover upwards at least substantially covers the fastening means at least substantially before the action of the derailed wheel and the same towards the rail, and the sensor provides a pressure, force , Weg- and / or acceleration sensor has.

Ein Druck-, Kraft-, Weg- und/oder Beschleunigungsaufnehmer als Fühler hat den Vorteil, dass Schwellenwerte eingestellt werden können, ab welchen ein erwünschtes Signal erreicht werden kann. Bei einem Lichtleiter oder elektrischen Leiter tritt, so dieselben durchtrennt werden, eine unmittelbare Indikation auf, die in der Regel nicht leicht auf die geminderte Höhe der einwirkenden Kräfte einstellbar, wie z. B. durch einen das Gleis Instandsetzenden, ist.A pressure, force, displacement and / or acceleration sensor as a sensor has the advantage that thresholds can be set, from which a desired signal can be achieved. In the case of a light guide or electrical conductor, if they are severed, an immediate indication occurs, which as a rule does not easily diminish Height of the acting forces adjustable, such. B. by the track repairing is.

Reicht die Abdeckung unter den Schienenkopf, so ist eine zusätzliche Absicherung gegen eine Beaufschlagung durch Räder von entgleisten Schienenfahrzeugen gegeben, da auch Schwingungen der Räder Berücksichtigung finden.If the cover extends below the rail head, an additional safeguard against being subjected to wheeling by derailed rail vehicles is given, as vibrations of the wheels are also taken into account.

Ist der Fühler durch einen Dehnmessstreifen gebildet, so kann ein besonders bewährter Fühler eingesetzt werden.If the sensor is formed by a strain gauge, a particularly proven sensor can be used.

Verläuft die Abdeckung im Wesentlichen parallel zu der Gleisebene, so können auch bei einer Mehrzahl von Fühlern eine gleichzeitige Beaufschlagung derselben und damit ein redundantes System zum Anzeigen erreicht werden. Weist die Abdeckung Ausnehmungen, z. B. Öffnungen, zur Betätigung der Befestigungsmittel für die Schienen auf, so ist ein besonders wartungsfreundliches System gegeben, da eine Wartung der Schienenbefestigung unabhängig von der Vorrichtung zum Anzeigen der Entgleisung erfolgen kann.If the cover extends essentially parallel to the track plane, it is also possible to achieve a simultaneous admission of the same to a plurality of sensors and thus a redundant system for displaying. Does the cover recesses, z. As openings, for actuating the fastening means for the rails, so a particularly maintenance-friendly system is given, since a maintenance of the rail fastening can be done independently of the device for displaying the derailment.

Ist die Abdeckung aus Metall, insbesondere Stahl, aufgebaut, so kann eine besondere Aufnahmefähigkeit der Impulse durch das entgleisende Fahrzeug gegeben sein, wobei mit Stahl auch eine längere Beanspruchung gewährleistet ist.If the cover is made of metal, in particular steel, then a special absorption capacity of the pulses can be given by the derailing vehicle, with steel also a longer stress is guaranteed.

Ist die Abdeckung mit dem Untergrund federnd verbunden, so kann eine Zerstörung des Untergrundes, z. B. Betonplatten, Holzschwellen, Betonschwellen, besonders geringfügig gehalten werden.If the cover is resiliently connected to the ground, it can destroy the substrate, z. As concrete slabs, wooden sleepers, concrete sleepers, are kept particularly small.

Schließt die Abdeckung in Ruhestellung im Wesentlichen mit einem oberen Ende des Befestigungsmittels ab, so kann die Beaufschlagung der Befestigungsmittel über die Räder besonders gering gehalten werden.Closes the cover at rest substantially with an upper end of the fastener, so the Loading the fasteners on the wheels are kept particularly low.

Sind zumindest zwei Fühler, insbesondere jeweils benachbart zu der/den Schiene(n), vorgesehen, so kann die Beaufschlagung durch die entgleisten Räder unmittelbar detektiert werden.If at least two sensors, in particular in each case adjacent to the rail (s), are provided, then the action by the derailed wheels can be detected directly.

Ist ein Fühler mittig zwischen den Schienen angeordnet, so kann eine Entgleisung des Schienenfahrzeuges in beiden Richtungen zur Fahrtrichtung gleichwertig angezeigt werden.If a sensor is arranged centrally between the rails, then a derailment of the rail vehicle in both directions can be displayed equivalent to the direction of travel.

Ist die Abdeckung der/des Fühler(s) unterhalb eines Schienenkopfes der, insbesondere zumindest zwei, Schienen angeordnet, so wird auf besonders einfache Art und Weise der Einfederung der Schienen Rechnung getragen.If the cover of the sensor (s) below a rail head of, in particular at least two, rails arranged, so the deflection of the rails is taken into account in a particularly simple manner.

Ist ein Ausgangssignal der/des Fühler(s) einem Warnsystem, insbesondere über einen Verstärker, zuleitbar, so kann eine Auswertung des Ausgangssignals besonders einfach durchgeführt werden.If an output signal of the sensor (s) can be fed to a warning system, in particular via an amplifier, an evaluation of the output signal can be carried out particularly easily.

Mit einer drahtlosen Übertragung des Ausgangssignals des Fühlers kann unabhängig von stationär gebundenen Systemen das Signal übermittelt werden.With a wireless transmission of the output signal from the sensor, the signal can be transmitted independently of stationary systems.

Ist die Energiezufuhr zu dem/den Fahrzeug(en) unterbrechbar und/oder eine Bremsung der/des Fahrzeuge(s) einleitbar, so kann bei einer Entgleisung eine rasche Beendigung der Fahrt des Zuges mit zumindest einem entgleisten Fahrzeug eingeleitet werden.If the energy supply to the vehicle (s) can be interrupted and / or braking of the vehicle (s) can be initiated, a rapid termination of the train's journey with at least one derailed vehicle can be initiated in the event of a derailment.

Ist der Fühler erst nach Überschreitung einer unteren Belastungs- bzw. Beschleunigungsgrenze betätigbar, so kann sichergestellt werden, dass auch beim Wartungspersonal eine Betätigung der erfindungsgemäßen Vorrichtung ausgeschlossen wird.If the sensor can only be actuated after a lower load or acceleration limit has been exceeded, it can be ensured that maintenance personnel also have a Operation of the device according to the invention is excluded.

Ist ein Fühler außerhalb des Bereiches zwischen den Schienen vorgesehen, und eine Abdeckung oberhalb der Befestigungsmittel angeordnet, so ist eine zusätzliche Sicherheit zur Anzeige von Entgleisungen gegeben.If a sensor is provided outside the region between the rails, and a cover is arranged above the fastening means, additional safety is provided for indicating derailments.

Sind die Fühler in Fahrtrichtung gesehen hintereinander angeordnet, so ist sicher gestellt, dass ein redundantes System angeordnet ist.If the sensors are arranged one behind the other in the direction of travel, then it is ensured that a redundant system is arranged.

Im Folgenden wird die Erfindung anhand der Zeichnungen näher erläutert.In the following the invention will be explained in more detail with reference to the drawings.

Die Schienen 1 definieren mit ihrer Schienenoberkante eine Gleisebene 2. Die Schienen sind mit einer Holzschwelle 3 über Schrauben 4 verbunden. Zwischen den Schienen sind Fühler 5 vorgesehen, die zwischen denselben und auch mittig derselben angeordnet sind. Diese Fühler sind durch Messdehnstreifen, also zur Messung der Belastung, der Kraft, der Wegänderung, aber auch durch Beschleunigungsfühler gebildet. Obwohl Dehnmessstreifen bevorzugt sind, können auch andere Fühler, wie beispielsweise piezoelektrische, hydraulische, pneumatische, schwingende Saiten eingesetzt werden.The rails 1 define with their rail top edge a track level 2. The rails are connected to a wooden sleeper 3 via screws 4. Between the rails feeler 5 are provided, which are arranged between the same and also centrally thereof. These sensors are formed by Meßdehnstreifen, so for measuring the load, the force, the path change, but also by acceleration sensor. Although strain gauges are preferred, other probes such as piezoelectric, hydraulic, pneumatic, vibrating strings may be used.

Die Abdeckung 6, welche bis unter den Schienenkopf reicht, weist weiters Ausnehmungen 9 auf, über welche die Befestigungsmittel 4 für die Schienen betätigt werden können.How out Fig. 2 clearly visible, the cover 6 has an angled portion 7 and 8 and in the directions of travel a, which serves for raising and lowering the wheels. The cover 6, which extends below the rail head, further has recesses 9, via which the fastening means 4 can be operated for the rails.

Das Ausgangssignal des Fühlers kann über einen Verstärker, beispielsweise über eine Funkanlage, weitergeleitet werden.The output signal of the sensor can be forwarded via an amplifier, for example via a radio system.

Auch kann vorgesehen sein, dass die Abdeckung federnd, beispielsweise über Metallfedern oder auch Kunststofffedern, wie gummielastische Zwischenlagen, mit dem Untergrund verbunden ist.It can also be provided that the cover is resiliently connected, for example via metal springs or plastic springs, such as rubber-elastic intermediate layers, to the substrate.

Der Fühler weist eine untere Grenze zur Betätigung auf, womit lediglich bei Überschreitung desselben ein Signal ausgelöst und damit auch weitergeleitet wird.The sensor has a lower limit to the operation, which is triggered only when it exceeds a signal and thus also forwarded.
