Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Antrieb von unabhängig drehenden Rädern eines Schienenfahrzeugs mit einer Antriebsachse, wobei der Antrieb von einem Motor über ein Untersetzungsgetriebe und ein mechanisches Differential erfolgt.The present invention relates to a device for driving independently rotating wheels of a rail vehicle with a drive axle, wherein the drive is provided by a motor via a reduction gear and a mechanical differential.
In bekannten derartigen Vorrichtungen enthalten die Achsen ein mechanisches Differential, das in einem die beiden Räder verbindenden Brückenträger untergebracht ist. Dies erfordert viel Platz zwischen den Rädern und schließt eine Absenkung des Flurs des Fahrzeugs aus.In known devices of this kind, the axles contain a mechanical differential housed in a bridge beam connecting the two wheels. This requires a lot of space between the wheels and precludes lowering the floor of the vehicle.
Ziel der vorliegenden Erfindung ist es, eine Vorrichtung zum Antrieb der Räder über eine Antriebsachse mit mechanischem Differential anzugeben, die es erlaubt, den Flur des Fahrzeugs abzusenken und somit den Zugang zum Fahrzeug zu erleichtern.The aim of the present invention is to provide a device for driving the wheels via a drive axle with a mechanical differential, which allows the floor of the vehicle to be lowered and thus facilitates access to the vehicle.
Die erfindungsgemäße Vorrichtung ist dadurch gekennzeichnet, daß das mechanische Differential außerhalb eines der Räder angeordnet ist, wobei eines der Ausgangszahnräder unmittelbar mit dem nächstliegenden Rad gekoppelt ist, während das andere Ausgangs-Zahnrad mit dem anderen Laufrad über eine Verbindungswelle gekoppelt ist.The device according to the invention is characterized in that the mechanical differential is arranged outside one of the wheels, one of the output gears being directly coupled to the nearest wheel, while the other output gear is coupled to the other impeller via a connecting shaft.
Außerdem enthält die Vorrichtung mindestens eines der nachfolgenden Merkmale:In addition, the device contains at least one of the following features:
- das mechanische Differential ist direkt mit der ersten Stufe des Reduziergetriebes gekoppelt.- the mechanical differential is directly coupled to the first stage of the reduction gear.
- Die Antriebsachse befindet sich innerhalb der Verbindungswelle.- The drive axle is located inside the connecting shaft.
- Die Motorausgangswelle verläuft senkrecht zur Antriebsachse.- The engine output shaft runs perpendicular to the drive axis.
- Die Motorausgangswelle verläuft parallel zur Antriebsachse.- The engine output shaft runs parallel to the drive shaft.
- Eine Bremsscheibe ist auf der Antriebswelle angebracht.- A brake disc is mounted on the drive shaft.
Nachfolgend werden beispielshalber und unter Bezugnahme auf die beiliegenden Zeichnungen eine bekannte und eine erfindungsgemäße Vorrichtung beschrieben.A known device and a device according to the invention are described below by way of example and with reference to the accompanying drawings.
Figur 1 zeigt eine bekannte Vorrichtung mit einem Differential in einer Brücke zwischen den Rädern.Figure 1 shows a known device with a differential in a bridge between the wheels.
Figur 2 zeigt eine erfindungsgemäße Vorrichtung mit einem Differential außerhalb der Räder.Figure 2 shows a device according to the invention with a differential outside the wheels.
In Figur 1 greift der Motor 1 mit seiner Welle ein Reduziergetriebe 2 an, das die Motorbewegung auf das Differential 3 überträgt, welches sich in einer Brücke 4 zwischen den Rädern 6 und 8 des Fahrzeugs befindet. Die antreibende Halbwelle 7 am Ausgang des Differentials treibt das Rad 8 an und die antreibende Halbwelle 5 treibt das Rad 6 an, und zwar gemäß einer Technik ähnlich der der Kraftfahrzeuge und Lastwagen.In Figure 1, the engine 1 engages with its shaft a reduction gear 2 which transmits the engine motion to the differential 3 located in a bridge 4 between the wheels 6 and 8 of the vehicle. The driving half-shaft 7 at the output of the differential drives the wheel 8 and the driving half-shaft 5 drives the wheel 6, according to a technique similar to that used in motor vehicles and trucks.
In Figur 2 verläuft die Verbindungswelle 20 innerhalb einer nicht drehbaren Hohlachse 21, um die die beiden Laufräder 12 und 13 drehen. Die Bewegung der Welle des Antriebsmotors 14 wird auf die Laufräder über ein Reduziergetriebe 15 übertragen, das zwei Reduzierstufen 16 und 17 besitzt. Hinter der ersten Reduzierstufe 16 des Reduziergetriebes ist ein mechanisches Differential 18 angeordnet, das das Antriebsdrehmoment auf das Laufrad 12 über eine Kupplung 19 und auf das Laufrad 13 über die eigentliche Motorwelle 20, die sich im Inneren der nicht drehenden Hohlachse 21 befindet, und über die Kupplung 11 verteilt. Das Bremsen der Achse wird durch eine Scheibenbremse 22 gewährleistet, die schematisch auf der Motorwelle angedeutet wurde.In Figure 2, the connecting shaft 20 runs inside a non-rotating hollow axle 21 around which the two impellers 12 and 13 rotate. The movement of the shaft of the drive motor 14 is transmitted to the impellers via a reduction gear 15, which has two reduction stages 16 and 17. Behind the first reduction stage 16 of the reduction gear, a mechanical differential 18 is arranged, which distributes the drive torque to the impeller 12 via a clutch 19 and to the impeller 13 via the actual motor shaft 20, which is located inside the non-rotating hollow axle 21, and via the clutch 11. The braking of the axle is ensured by a disk brake 22, which is schematically indicated on the motor shaft.
Wenn auch die Motorwelle als senkrecht zur Antriebsachse verlaufend dargestellt wurde, so ist es doch auch möglich, die Motorwelle parallel zur Antriebsachse anzuordnen.Although the motor shaft has been shown as running perpendicular to the drive axis, it is also possible to arrange the motor shaft parallel to the drive axis.
Die erfindungsgemäße Vorrichtung ist auf alle Schienenfahrzeuge mit zweiachsigen Fahrgestellen oder einer einzigen Achse anwendbar, deren Flurboden über die ganze Länge tiefliegt, insbesondere auf Straßenbahnwagen.The device according to the invention is applicable to all rail vehicles with two-axle chassis or a single axle, the floor of which is low over the entire length, in particular to tram cars.
