Description
Bei Lokomotiven sind als Vorderachsen bereits Laufachsen verwendet worden, die in
einem Deichselgesteli gelagert und bei denen ■ zwischen den!Laufachsbuchsen und dem Deichselgestell
Federn angeordnet sind. Durch die erzielte Höhen- und Seitenbeweglichkeit der Laufachse wird ein Einfahren der Lokomotive
in Krümmungen erleichtert. Immerhin entsprechen bei der bekannten Anordnung verhältnismäßig
kleine Federwege bereits erheblichen Änderungen des Raddruckes, so daß beim Einfahren
in Krümmungen mit starken Erhöhungen Stöße und harte Schläge auftreten können. Zu deren Vermeidung wird erfindungsgemäß
neben der angegebenen Federung eine zweite ' Federung zwischen dem Deichselgestell und
dem Lokomotivrahmen angeordnet. Diese Federung ist mittels Hebel mit der benachbarten
Achse in Verbindung gebracht,
so In der Zeichnung ist die Erfindung in Abb. 1 in einer Seitenansicht und in Abb. 2 im Grundriß
schematisch dargestellt.In locomotives, running axles have already been used as front axles, which are stored in a drawbar frame and in which springs are arranged between the running axle bushings and the drawbar frame. The achieved vertical and lateral mobility of the running axle makes it easier for the locomotive to enter bends. After all, with the known arrangement, relatively small spring deflections already correspond to considerable changes in the wheel pressure, so that when entering bends with strong increases, jolts and hard blows can occur. To avoid them, according to the invention, in addition to the specified suspension, a second suspension is arranged between the drawbar frame and the locomotive frame. This suspension is connected to the adjacent axle by means of a lever,
In the drawing, the invention is shown schematically in Fig. 1 in a side view and in Fig. 2 in plan.
α ist die Laufachse, b das Deichselgestell und c die benachbarte Achse. Das Deichselgestell ist bei d am Fahrzeugrahmen beweglich gelagert und mittels der Federn e gegen den Fahrzeugrahmen h abgefedert. Zur Achse c gehören die Federn/, und je ein Ende der Federn e und f sind miteinander durch, die am Fahrzeugrahmen h gelagerten Doppelhebel g verbunden. Die Achsbuchsen i der Achse a sind zwischen Gabeln am Deichselgesteli b angeordnet und stützen sich gegen dieses unter Zwischenschaltung der Federn k. α is the running axis, b the drawbar frame and c the adjacent axis. The drawbar frame is movably mounted on the vehicle frame at d and is sprung against the vehicle frame h by means of the springs e . The springs / belong to the axis c , and each end of the springs e and f are connected to one another by the double lever g mounted on the vehicle frame h . The axle sockets i of the axis a are arranged between forks on the Deichselgesteli b and are supported against this with the interposition of the springs k.
Erfordert die Gleislage eine Bewegung der Achse α beispielsweise nach oben, so werden einerseits die Federn k zusammengedrückt und anderseits die Federn e stärker gespannt, die vermöge des Hebels g einen Teil der Spannung auf die Federn f übertragen. Bei einer Bewegung der Laufachse α nach unten findet umgekehrt eine Entspannung der angegebenen Federn statt. Es ergibt sich hieraus eine erhebliche Vergrößerung der Federwege gegenüber der bekannten Anordnung.If the track position requires a movement of the axis α, for example upwards, then on the one hand the springs k are compressed and on the other hand the springs e are more strongly tensioned, which by means of the lever g transfer part of the tension to the springs f . Conversely, when the running axis α moves downward, the specified springs are relaxed. This results in a considerable increase in the spring travel compared to the known arrangement.
Die ungefederte, tote Masse besteht demgemäß nur aus der Laufachse α und den Achsbuchsen und ist somit gegenüber der bekannten Anordnung wesentlich verringert. Die Folge hiervon ist ein wesentlich sanfteres Fahren und eine große Schonung.des Oberbaues und des Fahrzeugrahmens. Die vergrößerten Federwege sichern anderseits die Achse c bei starken Gefällbrüchen gegen zu starke Be- oder Entlastung. The unsprung dead mass accordingly consists only of the barrel axis α and the axle bushings and is thus significantly reduced compared to the known arrangement. The consequence of this is a much smoother driving and a great deal of protection of the superstructure and the vehicle frame. On the other hand, the increased spring travel safeguards axis c against excessive loading or unloading in the event of a steep incline.
