Abstract
Description
Die Erfindung betrifft das Gebiet der Schienenfahrzeuge. Sie betrifft insbesondere einen Achsantrieb hierfür.The The invention relates to the field of rail vehicles. It concerns in particular an axle drive for this purpose.
Ein solcher Achsantrieb umfasst eine Laufradsatzwelle. Auf jedem Ende der Laufradsatzwelle sitzt ein Laufrad, das mit der Welle drehfest verbunden ist. Die Laufradsatzwelle ist von einem Motor angetrieben. Die Drehachsen von Laufradsatzwelle und Motor verlaufen parallel zueinander. Zwischen Motor und Laufradsatzwelle ist ein Getriebe geschaltet. Das Getriebe befindet sich zwischen einem der beiden Räder und dem Motor. Es umfasst ein großes Zahnrad, das auf die Laufradsatzwelle aufgekeilt ist, sowie ein Ritzel, das auf die Motorwelle aufgekeilt ist. Ritzel und Zahnrad kämmen miteinander. Ritzel und Zahnrad sind von einem Gehäuse umschlossen.One such final drive comprises a wheelset shaft. On each end The wheelset shaft is fitted with an impeller that rotates with the shaft connected is. The wheelset shaft is driven by a motor. The axes of rotation of the wheelset shaft and motor are parallel to each other. Between engine and wheelset shaft is a transmission connected. The gearbox is located between one of the two wheels and the engine. It includes a large one Gear that is keyed on the wheelset shaft, as well as a Pinion keyed on the motor shaft. Pinion and gear comb together. Pinion and gear are enclosed by a housing.
Es kann im Verlaufe der Lebensdauer eines solchen Achsantriebes zu einem Blockieren des Rotors des Motors kommen. Dies ist eine schwierige Situation für das Wartungspersonal, da das Schienenfahrzeug, somit die Lokomotive, nicht mehr mit eigenem Antrieb fahrtüchtig ist. Es bleibt somit nur das Abschleppen des Schienenfahrzeuges, was außerordentlich aufwendig ist, wenn sich das Fahrzeug auf der Strecke befindet.It can in the course of the life of such a final drive too blocking the rotor of the motor come. This is a difficult one Situation for the maintenance personnel, since the rail vehicle, thus the locomotive, is no longer roadworthy with its own drive. It stays that way only the towing the rail vehicle, which is extraordinary consuming is when the vehicle is on the track.
Will man das Abschleppen vermeiden, so bleibt nur als Ausweg, die Triebverbindung zwischen dem Motor und der Laufradsatzwelle zu unterbrechen. Auch dies ist schwierig und aufwendig, da hierzu der Motor vom übrigen Laufradsatz abmontiert werden muss.Want To avoid towing, so only as a way out, the drive connection between the engine and the wheelset shaft. Also This is difficult and expensive, since this is the engine from the rest of the wheelset must be removed.
Der Erfindung liegt die Aufgabe zugrunde, einen Achsantrieb der eingangs beschriebenen Art derart zu gestalten, dass ein Entkoppeln von Motor und Laufradsatzwelle leicht und schnell durchführbar ist.Of the Invention is based on the object, an axle drive of the beginning described type such that a decoupling of engine and Wheelset shaft is easy and fast to carry out.
Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.These The object is solved by the features of claim 1.
Der Erfinder hat einen verblüffend einfachen Weg gefunden. Demgemäß lässt sich das Getriebegehäuse im Bereich des Ritzels auf der Seite des dort befindlichen Laufrades öffnen. Die Weite des Zwischenraumes zwischen dem Ritzel und dem Laufrad ist im Allgemeinen wenigstens gleich der Länge des Ritzels. Das Ritzel ist von der Motorwelle leicht abziehbar und in den Zwischenraum verbringbar. Damit ist die drehfeste Verbindung zwischen Ritzel und Laufradsatzwelle des Motors gelöst, und zugleich die Triebverbindung zwischen Motor und Laufradsatzwelle aufgehoben. Das Ritzel kann nunmehr provisorisch in dem Zwischenraum gehalten werden. Die Blockade des gesamten Fahrzeuges durch den schadhaften Antrieb ist aufgehoben, und das Fahrzeug kann mit Hilfe weiterer Antriebe aus eigener Kraft weiterfahren.Of the Inventor has a startling found easy way. Accordingly, it is possible the gearbox in the area of the pinion on the side of the impeller located there. The Width of the gap between the pinion and the impeller is generally at least equal to the length of the pinion. The pinion is easily removable from the motor shaft and into the gap be brought. This is the rotatable connection between pinion and wheelset shaft of the engine solved, and at the same time the drive connection canceled between engine and wheelset shaft. The pinion can now temporarily held in the gap. The blockade of the entire vehicle due to the faulty drive is canceled, and the vehicle can with the help of further drives on its own continue.
Gemäß einem weiterführenden Gedanken sind Vorkehrungen getroffen, um das Ritzel nach dem Abziehen von der Motorwelle und nach dem Verbringen in den Zwischenraum auch noch in Laufradialer Richtung zu verschieben, und zwar senkrecht zur Laufradsatzwelle des Achsantriebes über den Außenumfang des Laufrades hinaus. In dieser Position lässt es sich durch weiteres Verschieben parallel zur Achse der Laufradsatzwelle entnehmen.According to one secondary Thoughts are precautions taken to pull the pinion off from the motor shaft and after spilling into the gap as well still to move in the radial direction, and that vertically to the wheelset shaft of the final drive beyond the outer circumference of the impeller. Leave in this position it is by further displacement parallel to the axis of the wheelset shaft remove.

Are in the gearbox but arranged no gear bearings, as shown in the Case, so the case serves only the protection and the oil supply.
