Description

Kabeltrommel für ortsbewegliche, elektrisch angetriebene Fahrzeuge Bei Kabeltrommeln für ortsbewegliche, elektrisch angetriebene Geräte und Fahrzeuge, auf die das auf- und :abzuwickelnde Kabel in der für diese Trommeln üblichen Weise mit dicht aneinanderliegenden Windungen in mehreren Lagen aufgewickelt wird, hat sich gezeigt, daß die Ableitung der beim Stromdurchfluß entstehenden Wärme Schwierigkeiten bietet, die um so größer werden, je länger das aufzuwickelnde Kabel und-je größer die durch das Kabel geführte Leistung und die Spezifische Belastung des Kabels sind.Cable drum for mobile, electrically powered vehicles In the case of cable drums for mobile, electrically powered devices and vehicles, on the cable to be wound up and: in the manner customary for these drums is wound with tightly spaced turns in several layers, has it has been shown that the dissipation of the heat generated when the current flows through difficulties offers, which become larger, the longer the cable to be wound up and the larger are the power passed through the cable and the specific load on the cable.

Man hat versucht, durch Verwendung von guten Wärmeleitern für den Mantel und die Seitenwangen der Wickeltrommel, oder durch Einbau von Ventilatoren, die im Trommelinnern einen Luftüberdruck @erzeugen, diesem Übelstand abzuhelfen. Diese Maßnahmen haben jedoch zu keinem befriedigenden Erfolg geführt, weil sie gerade dort, wo es infolge der dicht neben- und übereinanderliegenden Kabelwindungen zu Wärmestauungen kommt, unwirksam bleiben. Der Vorschlag, nur zwei Kabellagen aufzuwickeln, so daß die eine von außen und die ;andere von innen her von Luft umspült wird, ist mit Rücksicht auf die sich dann ergebenden außerordentlich großen Abmessungen für die Wickeltrommeln für die Mehrzahl der Bedarfsfälle undurchführbar.Attempts have been made by using good heat conductors for the Jacket and the side walls of the winding drum, or by installing fans, which generate excess air pressure inside the drum to remedy this problem. However, these measures have not led to satisfactory results because they are precisely where it closes due to the tightly adjacent and superimposed cable windings Heat build-up occurs, remain ineffective. The suggestion to wind up only two layers of cable, so that one is surrounded by air from the outside and the other from the inside with regard to the resulting extremely large dimensions for the winding drums are impracticable for the majority of cases.

Die vorliegende Erfindung behebt die bestehenden Mängel durch Aufwickeln des Kabels in ,an sich bekannter Weise so, daß zwischen den nebeneinanderliegenden Windungen ein Luftspalt bleibt, und daß gleichzeitig ;auf bekannte Art der Trommelmantel und gegebenenfalls auch die Seitenwangen gelocht oder aus Stäben bestehend so ausgebildet sind, daß Luft durch den Trommelmantel und die Seitenwangen treten kann, wobei der auf bekannte Art und Weise gerillte oder mit besonderen Kabelstützen versehene Trommelmantel die gegenseitige Lage der Kabelwindungen sichert. Bei einem so in mehreren Lagen ,aufgewickelten Kabel kann sich Luft durch die vorhandenen Kanäle bewegen, und es wird zu keinen den Bestand des Kabels gefährdenden Wärmestauungen kommen.The present invention overcomes the existing deficiencies by winding of the cable in a manner known per se so that between the adjacent Windings an air gap remains, and that at the same time; in the known manner of the drum shell and, if necessary, the side cheeks are perforated or made up of rods in this way are that air can pass through the drum shell and the side walls, the drum casing grooved in a known manner or provided with special cable supports ensures the mutual position of the cable windings. With one in several layers , coiled cable can move air through the existing ducts, and it there will be no build-up of heat that could endanger the cable's existence.

In Abb. z und 2 ist die Lage des Kabels auf dem mit einer Rille versehenen, in Stäbe unterteilten Trommelmantel dargestellt. Die schraubenförmig umlaufende Rille zur Fülirang des Kabels hat eine größere Steigung als der Durchmesser des Kabels, so daß zwischen zwei. nebeneinanderliegenden Windungen des Kabels ein Luftspalt bleibt. Ist die in dem Trommelmantel eingeschnittene Rill: z. B. rechtsgängig, dann muß die zweite Kabellage linksgängig gewickelt werden. Hierdurch bilden sich zwischen den einzelnen Windungen der verschiedenen Lagen Lüftringkanäle, durch welche die im Kabel ;auftretende Wärme abgeleitet wird: In Abb" 3 ist :ein Trommelmantel dargestellt, auf dem Kabelstützen verschiedener Form ,angeordnet sind: Die Kabelstützen werden so durchgebildet, daß die Luft durch den Trommelmantel nach den- Kabelwindungen und umgekehrt strömen kann.In fig. Z and 2 the position of the cable on the grooved, Drum shell divided into bars is shown. The helical circumferential The groove for the full grade of the cable has a greater pitch than the diameter of the Cable so that between two. adjacent turns of the cable create an air gap remain. Is the groove cut in the drum shell: z. B. right hand, then the second cable layer must be wrapped to the left. This creates between the individual turns of the various layers of ventilation ring channels through which the in the cable; occurring heat is dissipated: In Fig "3: a drum jacket is shown, on the cable supports of various shapes, are arranged: The cable supports are formed so that the air through the drum jacket after the cable windings and vice versa can flow.
