Description
Die Erfindung betrifft Puffer für Eisenbahnfahrzeuge mit hoher Geschwindigkeit. Die Erreichung einer solchen von über 120 km in der Stunde ist praktisch nur dann möglich, wenn man nicht nur die Außenwände des Fahrzeuges möglichst glatt hält, sondern auch mit seinen herausstehenden Bauteilen den Wagenenden eine Form gibt, die sowohl bei Vorwärts- als auch, bei Rückwärtsfahrt eine erhebliche Herabsetzung des LuftwiderStandes gegenüber den bisher üblichen Wagenformen gewährleistet, und es also vermeidet, aus dem eine annähernde Tropfenform besitzenden Fahrzeuge irgendwelche Teile hervorragen zu lassen, die eine erhebliche Störung der Stromlinien hervorrufen. Da gerade die Puffer, auf welche man schon wegen der bestehenden Sicherheitsvorschriften nicht verzichten kann, in ihrer gewöhnlichen Gestalt hierzuThe invention relates to buffers for high speed railway vehicles. the Achievement of such a distance of over 120 km in the lesson is practically only possible if you don't just look at the outer walls of the Keeps the vehicle as smooth as possible, but also with its protruding components The end of the car gives a shape that can be used for both forward and reverse travel considerable reduction in air resistance guaranteed compared to the previously usual car shapes, and thus avoids getting out of the Vehicles which have an approximately teardrop shape have some parts protruding from them that cause a significant disruption of the streamlines. Since the buffers Which one cannot do without because of the existing safety regulations can do this in its usual form
ίο sehr Veranlassung geben, sind entsprechend der Erfindung die Puffer sowie ihre Gehäuse in ihren Formen ebenfalls der Tropfenform, soweit es irgend möglich ist, angepaßt, so daß der Luftwiderstand nur unwesentlich größer ist als bei vollständig fehlender Pufferung. Auf der Zeichnung ist eine Ausführungsform, des Erfindungsgegenstandes als Beispiel dargestellt, und zwar zeigen die Abb. 1, 2 und 3 eine Längsansicht, einen Grundriß und eine Vorderansicht des vorderen oder hinteren Teiles eines mit den neuen Puffern versehenen Schnelltriebwagens und Abb. 4 einen Längsschnitt durch den Pufferkörper selbst nach der Linie a-b der Abb. 2.ίο give very reason, according to the invention, the buffer and its housing in their shapes are also adapted to the drop shape, as far as possible, so that the air resistance is only slightly greater than in the case of completely missing buffering. In the drawing, an embodiment of the subject matter of the invention is shown as an example, namely Figs. 1, 2 and 3 show a longitudinal view, a plan and a front view of the front or rear part of a high-speed railcar provided with the new buffers and Fig. 4 shows a longitudinal section through the buffer body itself according to the line from Fig. 2.
Die Einrichtung besteht im wesentlichen aus Pufferkörpern 1, die auf jeder Seite aus der parabelf örmig gestalteten Stirnwand 2 des Wagens nach vorn herausragen. Diese Pufferkörper werden zweckmäßig aus Formeisen 3, 4 gebildet, welche mit den Wand- und Untergestellteiien des Wagenkastens fest verbunden und durch Deckplatten 5 und 6 abgedeckt sind. In eine Höhlung des so entstandenen kastenartigen Körpers sind die Puffer 7 eingesetzt. Die Puffer können in der verschiedensten Weise federnd. ausgebildet sein. So können sie in bekannter Weise aus Gummi bestehen, so daß sie in sich selbst federn, oder aber sie können aus Hartholz oder Eisen bestehen und sich gegen besondere Federn abstützen. Die ganze Pufferbohle ist mit Ausnahme der Stoßflächen der Puffer mit Blech 9 stromlinienförmig und tragflächenartig verkleidet. Dabei ist die Verkleidung so angeordnet, daß die Richtung geringsten Luft-Widerstandes (Pfeil 8) von dem zugehörigen Stirnende nach der Mitte des Fahrzeuges hin ansteigt. Dies ist notwendig, da die Luftströmung am Wagenkopfe schräg aufwärts und am Wagenende schräg abwärts gerichtet ist.The device consists essentially of buffer bodies 1, which are made on each side the parabolic end wall 2 of the car protrude to the front. This buffer body are expediently formed from shaped iron 3, 4, which with the wall and Unterstelleiien of the car body firmly connected and covered by cover plates 5 and 6 are. The buffers 7 are inserted into a cavity in the box-like body thus created. The buffers can be resilient in a variety of ways. be trained. So they can be made of rubber in a known manner, so that they spring in themselves, or they can be made of hardwood or iron and resist special feathers prop up. With the exception of the abutment surfaces, the entire buffer beam is made of sheet metal 9 Streamlined and clad like a wing. The cladding is arranged in such a way that that the direction of least air resistance (arrow 8) from the associated front end towards the middle of the vehicle increases. This is necessary because the air flow at the head of the car is inclined upwards and is directed obliquely downwards at the end of the car.
