Description

Die Erfindung betrifft eine Radsatzführung gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a wheelset guide according to the Preamble of the first claim.

Bei einer bekannten Radsatzführung dieser Art (DD-A 2141) ist an einem Drehgestell für Schienenfahrzeuge der Drehgestellahmen über je zwei Schraubenfedern als Primärfedern auf Radlagergehäusen von Radsätzen elastisch gelagert. Der Drehgestellrahmen trägt einen Wagenkasten. Die Schraubenfedern sitzen jeweils zwischen einer am Drehgestellrahmen festgesetzten oberen, topfförmigen Grundplatte und einer auf einer Konsole des Achslagergehäuses aufsitzenden unteren Grundplatte. Die untere Grundplatte ist dabei mittels eines konzentrisch innerhalb der Schraubenfeder angeordneten Notführungszapfens am Achslagergehäuse festgeschraubt. Das obere Ende des Notführungszapfens durchgreift mit radialem Spiel eine Bohrung im Boden der oberen Grundplatte, wobei oberhalb des Bodens am freien Ende des Notführungszapfens ein ortsfester Endanschlag vorgesehen ist, der mit dem als Gegenanschlag dienenden Boden der oberen topfförmigen Grundplatte so zusammenwirkt, daß bei einer im Betrieb des Drehgestells auftretenden Gewichtsentlastung die obere Grundplatte und damit auch der Drehgestellrahmen gegenüber dem Zugehörigen Achslagergehäuse nur entsprechend begrenzt durch dazugehörige Schraubenfedern nach oben angehoben werden kann. Bei Federbruch dient die untere Grundplatte als weiterer Endanschlag. Von Nachteil ist bei dieser Anordnung, daß die Bewegung zwischen Drehgestellrahmen und Radsatz durch die Endanschläge fest vorgegeben ist.In a known wheelset guide of this type (DD-A 2141) on a bogie for rail vehicles the bogie frame via two coil springs as primary springs Wheel bearing housings of wheel sets elastically supported. Of the Bogie frame carries a car body. The coil springs each sit between one fixed to the bogie frame upper, pot-shaped base plate and one on one Console of the lower bearing base seated on the axle bearing housing. The lower base plate is concentric emergency guide pin arranged inside the coil spring on Axle bearing housing screwed tight. The top end of the emergency guide pin passes through a hole in the radial clearance Bottom of the upper base plate, above the bottom on a fixed end stop at the free end of the emergency guide pin is provided with the bottom serving as a counterstop the upper pot-shaped base plate interacts so that at a weight relief occurring during operation of the bogie the upper base plate and thus also the bogie frame compared to the associated axle bearing housing only accordingly limited by the associated coil springs can be lifted up. If the spring breaks, the lower one serves Base plate as another end stop. A disadvantage is this arrangement that the movement between bogie frames and wheelset is fixed by the end stops.

Beim Einbau zwischen Karosserie und Radträger wird außer der Spannschraube auch die untere, zwischen zwei Windungen der äußeren Wendelder hilfsweise eingesetzte Stützteller entfernt. Soll diese Federeinheit wieder ausgebaut werden, muß die Stützscheibe bei völlig entspannter innerer Schraubenfeder wieder zwischen die betreffenden beiden Windungen der äußeren Schraubenfeder eingesetzt werden, wonach mittels der ebenfalls wieder einzusetzenden Spannschraube das Federpaket wieder in die gespannte Lage zurückversetzt wird.It is also a spring pack for elastic support Motor vehicle body on a wheel carrier known (EP-A2-0 281 173), which consists of two coaxially arranged one inside the other Coil springs are made by means of a concentric Clamping screw and two clamping washers axially compressible are and initially form a compressed unit. At the Installation between the body and the wheel carrier is not included Tension screw also the lower one, between two turns of the outer helix auxiliary support plate removed. If this spring unit is to be removed again, the Support disc with completely relaxed inner coil spring again between the relevant two turns of the outer one Coil spring are used, according to which also the spring assembly to be reinserted the tense situation is set back.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Radsatzführung gemäß dem Oberbegriff des ersten Anspruchs Maßnahmen zu treffen, durch welche auf einfache Weise eine verbesserte Begrenzung des Ein- und Ausfederns der Primärfedern zwischen Drehgestellrahmen und Radsatz erreicht wird.The invention has for its object in a Wheelset guidance according to the preamble of the first claim Take measures by which a improved limitation of the compression and rebound of the primary springs between the bogie frame and the wheelset.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmal des ersten Patentanspruchs.This object is achieved according to the invention by characteristic feature of the first claim.

Bei einer Ausgestaltung einer Radsatzführung gemäß der Erfindung übernimmt der Notführungszapfen mit den beiden daran vorgesehenen Endanschlägen allein die Begrenzung der Bewegung zwischen Drehgestellrahmen und Radsatz, wobei die Endanschläge verstellbar gehalten sind.
