Description
Die Erfindung betrifft eine weitere Ausbildung des Puffers nach Patent 437638 und besteht darin, daß jedes Ende der Pufferfeder zwischen zwei voneinander getrennten Ringen eingespannt ist.The invention relates to a further embodiment of the buffer according to patent 437638 and is that each end of the buffer spring between two separate Rings is clamped.
Auf der Zeichnung ist der Gegenstand der Erfindung im achsialen Schnitt veranschaulicht. In the drawing, the subject of the invention is illustrated in axial section.
Der Pufferstößel A ist in der Pufferhülse B verschiebbar und trägt als Hubbegrenzer wirkende Schrauben α·1, die mit Längsschlitzen b1 der Pufferhülse in Eingriff stehen. Die Pufferfeder besteht aus zwei ineiriandergeschraubten Schraubenfedern C und D, deren Windungen sich auch bei unbelastetem Puffer mit Keilflächen c1 und d1 berühren.The buffer plunger A is displaceable in the buffer sleeve B and carries screws α · 1 which act as stroke limiters and which engage with longitudinal slots b 1 of the buffer sleeve. The buffer spring consists of two helical springs C and D screwed into one another, the turns of which touch with wedge surfaces c 1 and d 1 even when the buffer is not under load.
Mit den freien Enden der Schraubenfeder stehen innen und außen Ringe E bzw. F in Eingriff, die voneinander getrennt sind, und zwar ist die Anordnung so getroffen, daß die Ringe unter beträchtlicher Vorspannung stehen.With the free ends of the helical spring are inside and outside rings E and F in engagement, which are separated from each other, and the arrangement is such that the rings are under considerable bias.
Die bei Belastung des Puffers infolge der Keilwirkung in den Federwindungen auftretenden radialen Kräfte, die an den Federenden nicht durch Zug- und Druckspannungen im Federquerschnitt aufgenommen werden können, vergrößern den Druck, mit dem die Federenden an den Ringen E und F anliegen, so daß infolge der entstehenden Reibung Relativbewegungen zwischen den Federenden und Ringen und zwischen den ineinandergreifenden Enden der beiden Federn C und D nicht eintreten können.The radial forces occurring when the buffer is loaded due to the wedge effect in the spring coils, which cannot be absorbed at the spring ends by tensile and compressive stresses in the spring cross-section, increase the pressure with which the spring ends rest on the rings E and F , so that as a result the resulting friction relative movements between the spring ends and rings and between the interlocking ends of the two springs C and D cannot occur.
Der gegenüber der Anordnung nach dem Hauptpatent erzielte Fortschritt besteht darin, daß das Befestigen der Federenden in den Ringen JS, F erheblich vereinfacht ist, da nach dem Einschlagen oder Einpressen der inneren Ringe E die äußeren Ringe F nur in erhitztem Zustande aufgeschoben zu werden brauchen, damit die erforderliche Vorspannung erzielt wird.The progress achieved compared to the arrangement according to the main patent is that the fastening of the spring ends in the rings JS, F is considerably simplified, since after the inner rings E have been knocked in or pressed in, the outer rings F only need to be pushed on when they are heated, so that the required preload is achieved.
