Description

Die Erfindung betrifft eine Schienenabtastung für Spurkranzschmieranlagen, bei denen die Schmierimpulse von einer Steuerung ausgelöst werden, die wegabhängig und/oder bogenabhängig und/oder zeitabhängig arbeitet.The invention relates to a rail scanning for wheel flange lubrication systems, in which the lubrication pulses are triggered by a controller that works path-dependent and / or arc-dependent and / or time-dependent.

Spurkranz-Schmierungen bei Schienenfahrzeugen dienen dem Zweck, den Verschleiß des Rades und der Schiene im Bereich des Spurkranzes des Rades zu verringern. Vorwiegend findet man Spurkranz-Schmierungen an der Lenkachse von Lokomotiven, aber auch Schienenfahrzeugen anderer Art, wie Straßenbahnen. Die Schmierung erfolgt vornehmlich mit wasserfesten und kältebestandigen Schmiermitteln, wobei die Schmierimpulse von einer Steuerung ausgelöst werden. Das Schmiermittel wird mittels Druckluft auf die Spurkränze gesprüht und während der Fahrt selbsttätig über die Schienenflanken auch auf die Spurkränze der nachfolgenden Radsätze übertragen. Spurkranzschmierungen dieser Art sind bekannt.Wheel flange lubrication in rail vehicles serves the purpose of reducing the wear of the wheel and the rail in the area of the wheel flange. Mainly there is wheel flange lubrication on the steering axle of locomotives, but also other types of rail vehicles, such as trams. Lubrication is primarily carried out with waterproof and cold-resistant lubricants, with the lubrication pulses being triggered by a control system. The lubricant is sprayed onto the wheel flanges by means of compressed air and automatically transferred to the wheel flanges of the following wheelsets while driving. Wheel flange lubrication of this type is known.

Ein grundsätzliches Problem bei Spurkranzschmierungen besteht darin, die Schmierimpulse zum korrekten Zeitpunkt auszulösen und den Schmierstoff an der richtigen Stelle, nämlich dem Spurkranz des gerade anlaufenden Rades, aufzutragen. Bislang ist versucht worden, diese Probleme mit wegabhängigen und/oder bogenabhängigen und/oder zeitabhängigen Steuerungen zu lösen. Bei der wegabhängigen Steuerung wird nach einer bestimmten Wegstrecke, beispielsweise alle 200m, ein Schmierimpuls ausgelöst. Die Strecke wird über einen Wegegeber gemessen. Dabei ist es unerheblich, ob der Zug sich auf einer Geraden bewegt oder einen Bogen befährt.A fundamental problem with wheel flange lubrication is to trigger the lubrication impulses at the correct time and to apply the lubricant at the right place, namely the wheel flange of the wheel just starting up. So far, attempts have been made to solve these problems with path-dependent and / or arc-dependent and / or time-dependent controls. With the path-dependent control, a lubrication pulse is triggered after a certain distance, for example every 200m. The distance is measured using a path encoder. It is irrelevant whether the train is moving on a straight line or traveling on an arc.

Bei der bogenabhängigen Steuerung werden die Schmierimpulse durch Fliehkraftschalter ausgelöst, welche auf Linksbögen oder Rechtsbögen reagieren und die Schmierung der jeweils anlaufenden Seite auslösen. Eine Optimierung kann durch Beschleunigungsgeber oder Neigungswinkelmesser durchgeführt werden, wobei davon ausgegangen wird, daß eine Querbeschleunigung des Zuges gleichbedeutend mit dem Anliegen eines Spurkranzes an der Schiene ist.In the case of the arc-dependent control, the lubrication pulses are triggered by centrifugal switches which react to left-hand or right-hand turns and trigger the lubrication of the side that is approaching. Optimization can be carried out using accelerometers or inclinometers are, it is assumed that a lateral acceleration of the train is synonymous with the presence of a wheel flange on the rail.

Bei der zeitabhängigen Steuerung wird der Schmierimpuls mittels eines Relais ausgelöst, dessen Impuls- und Pausenzeiten einstellbar sind. Sämtliche obengenannten Steuerarten sind kombinierbar und bei ein- bzw. mehrachsigen Zügen einsetzbar.With the time-dependent control, the lubrication pulse is triggered by a relay whose pulse and pause times can be set. All of the above-mentioned types of tax can be combined and used for single or multi-axle trains.

Die beschriebenen bekannten Systeme haben verschiedene Nachteile. So werden beispielsweise bei der reinen Zeit- und Wegeschmierung Schmierimpulse zu Zeitpunkten ausgelöst, wo eine Schmierung nicht erforderlich ist. Überschmierungen, die Verschmutzungen verursachen, sind die Folge. Bei der bogenabhängigen Steuerung können Verfälschungen dadurch eintreten, daß die Bahnneigung der Schiene und die Geschwindigkeit des Zuges sich gerade so aufeinander abstimmen, daß die resultierende Kraft aus Zentrifugalkraft und Erdbeschleunigung genau senkrecht über der Schiene steht, so daß kein Schmierimpuls ergeht, obwohl Spurkranzanlagen gegeben sind und eine Schmierung erforderlich wäre. Schließlich ist nachteilig, daß die beschriebenen Steuerungen nicht auf Wetterbedingungen reagieren, so daß beispielsweise auch dann Schmierungen ausgelöst werden, wenn keine Schmierung gewünscht ist oder eine Verringerung der Schmierung sinnvoll wäre, beispielsweise bei Regen.The known systems described have various disadvantages. For example, with pure time and path lubrication, lubrication pulses are triggered at times when lubrication is not required. The result is over-lubrication that causes contamination. In the case of the arc-dependent control, falsifications can occur in that the inclination of the rail and the speed of the train are coordinated with one another in such a way that the resulting force from centrifugal force and acceleration due to gravity is exactly perpendicular to the rail, so that no lubrication pulse is emitted, although there are wheel flange systems and lubrication would be required. Finally, it is disadvantageous that the controls described do not react to weather conditions, so that, for example, lubrications are also triggered when no lubrication is desired or a reduction in the lubrication would make sense, for example in the rain.

Der Erfindung liegt die Aufgabe zugrunde, mit einem kombinierten Abtastsystem und einer entsprechend gestalteten Elektronik eine intelligente Schmierimpulsauslösung zu entwickeln, die sowohl das Anlaufen des Spurkranzes an der Schiene unmittelbar abtastend ermittelt als auch zwischen trockenem Wetter und Regenwetter unterscheidet.The invention has for its object to develop an intelligent lubrication pulse triggering with a combined scanning system and a correspondingly designed electronics, which both detects the start of the wheel flange on the rail immediately and also distinguishes between dry weather and rainy weather.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß Impulsgeber für die Auslösung des Schmierimpulses eine Lichtschranke ist, deren Signal in Kombination mit einem Beschleunigungsgeber und/oder Neigungswinkelgeber und/oder Wegegeber von einer Steuerelektronik ausgewertet wird. Mittels einer Lichtschranke lassen sich Bewegungen des Rades außerordentlich genau über eine aus Sender und Empfänger bestehende Einrichtung verfolgen. Für das Anlaufen des Spurkranzes an der Schiene beträgt der seitliche Weg des Rades ca. 6mm und die Hysterese der Lichtschranke von ca ± 0,5mm läßt einwandfrei Bewegungen in der Größenordnung von 1 mm erkennen und somit den Schaltpunkt zum Ansprechen der Schmieranlage identifizieren. Vorzugsweise ist daher als Impulsgeber am Drehkranz des entsprechenden Radsatzes des Schienenfahrzeugs eine Infrarotsender-Empfangseinheit befestigt, deren Lichtschranke so eingestellt ist, daß bei einem Anlaufen des Rades eine Reflexion der Lichtschranke an der Schiene stattfindet und zur Auslösung eines Schmierimpulses herangezogen werden kann.The object is achieved in that the pulse generator for triggering the lubrication pulse is a light barrier, the signal of which is evaluated in combination with an acceleration sensor and / or angle sensor and / or position sensor by control electronics. Movements of the wheel can be made extremely precisely by means of a light barrier track via a facility consisting of transmitter and receiver. For the wheel flange to run against the rail, the wheel's lateral travel is approx. 6 mm and the hysteresis of the light barrier of approx. ± 0.5 mm allows flawless movements in the order of magnitude of 1 mm to be recognized and thus the switching point to respond to the lubrication system identified. An infrared transmitter / receiver unit is therefore preferably attached as a pulse generator to the slewing ring of the corresponding wheel set of the rail vehicle, the light barrier of which is set such that when the wheel starts up a reflection of the light barrier on the rail takes place and can be used to trigger a lubricating pulse.

Bei trockenem Wetter ist dies zur Auslösung eines Schmierimpulses ausreichend. Bei Regenwetter gerät ein Wassernebel zwischen die Sender-Empfängereinheit und die Schiene und es ist dem System nicht mehr möglich, die Schiene selbst zu erkennen. Es wird ein spezifisches Dauersignal bei Regen erzeugt, welches sich von dem normalen Reflexionssignal unterscheidet. Um auch in diesem Fall eine sinnvolle, nämlich verringerte Schmierung auszulösen, ist vorgeschlagen, den Lichtschrankenimpulsgeber zu kombinieren mit einem mechanischen Beschleunigungsgeber und/oder Neigungswinkelgeber und/oder Wegegeber und über eine Steuerelektronik die Impulse auszuwerten. Wenn die Sender/Empfänger-Einheit des Lichtschrankenimpulsgebers aufgrund der Eigenart des Signales "Regen" erkennt, werden die Signale des Beschleunigungsgebers und/oder Neigungswinkelgebers und/oder Wegegebers von der Steuerelektronik verwertet, wobei diese in ihrem Programm berücksichtigt, daß bei Regen mit einer wesentlichen Verringerung der Schmierung auszukommen ist.In dry weather, this is sufficient to trigger a lubrication pulse. In rainy weather, a water mist gets between the transmitter-receiver unit and the rail and it is no longer possible for the system to recognize the rail itself. A specific continuous signal is generated when it rains, which differs from the normal reflection signal. In order to trigger a sensible, namely reduced lubrication in this case as well, it is proposed to combine the light barrier pulse generator with a mechanical acceleration sensor and / or inclination angle sensor and / or travel sensor and to evaluate the pulses via control electronics. If the transmitter / receiver unit of the light barrier pulse generator recognizes "rain" due to the nature of the signal, the signals from the accelerometer and / or inclination angle sensor and / or position sensor are used by the control electronics, which takes into account in its program that with rain a significant amount Reduction of lubrication is sufficient.

Vorzugsweise ist der Lichtschrankenimpulsgeber am Drehkranz des Schienenfahrzeugs höhen- und quereinstellbar zur Schiene angeordnet.The light barrier pulse generator is preferably arranged on the slewing ring of the rail vehicle and is adjustable in height and crosswise to the rail.
