Kontaktrollen laufen.Contact rollers run.
Patentiert im Deutschen Reiche vom 5. Oktober 1909 ab. Patented in the German Empire on October 5, 1909.
Die Erfindung betrifft einen zweipoligen Stromabnehmer für elektrisch betriebene gleislose Fahrzeuge, und zwar derjenigen Art, bei welcher die beiden senkrecht übereinander angeordneten Fahrdrähte derart umfaßt werden, daß die stromabnehmenden Teile von oben und von unten an die Drähte federnd angedrückt werden. Solche Stromabnehmer sind, wie in der Patentschrift 215978, Kl. 20I, beschrieben ist, in der Weise ausgeführt worden, daß auf der Oberseite des oberen Fahrdrahtes zwei hintereinander angeordnete Kontaktrollen laufen, die um senkrechte, durch die Rollenmittelpunkte gelegte Achsen drehbar sind, während auf der Unterseite des unteren Fahrdrahtes eine ähnlich gelagerte Rolle läuft. Bei solchen Stromabnehmern ist zwar die Gefahr einer Entgleisung nahezu ausgeschlossen, selbst wenn starke seitliche Spannungen im Schlepptau auftreten; aber solche Spannungen übertragen sich auf die Fahrdrähte, die dadurch stark beansprucht werden.The invention relates to a two-pole pantograph for electrically operated trackless Vehicles of the type in which the two are arranged vertically one above the other Contact wires are included in such a way that the current-consuming parts are resiliently pressed against the wires from above and below will. Such current collectors are as described in patent specification 215978, class 20I has been carried out in such a way that on top of the upper contact wire two contact rollers arranged one behind the other run around vertical ones through the roller centers Laying axes can be rotated, while a similarly mounted roller runs on the underside of the lower contact wire. With such pantographs the risk of derailment is almost impossible, even if there is strong lateral tension in the tow; but such tensions are transferred to the contact wires, which are heavily stressed as a result.
Die Erfindung besteht nun darin, daß die am unteren Fahrdraht laufende Rolle durch einen entsprechend ausgeführten Schleifbügel ersetzt wird. Dadurch wird vermieden, daß beim Auftreten seitlicher Zugkräfte der untere Fahrdraht beansprucht wird, und erreicht, daß der Stromabnehmer um einen gewissen Winkel seitlich ausschwingen kann, ohne daß dabei die Gefahr des Entgleisens entsteht.The invention consists in the fact that the roll running on the lower contact wire through an appropriately designed grinding hanger is replaced. This avoids that when lateral tensile forces occur, the lower contact wire is stressed and achieved, that the pantograph can swing out to the side at a certain angle without thereby the risk of derailment arises.
In der Zeichnung ist der Stromabnehmer nach der Erfindung in Fig. 1 in einer Seitenansicht und in Fig. 2 in einem Schnitt nach der Linie 2-2 in Fig. 1 dargestellt. Die am oberen Fahrdraht i laufenden Rollen c sind in bekannter Weise durch Joch α miteinander verbunden. Die Tragstange d, die gemäß Fig. 2 nach einer Seite ausgebogen ist, durchsetzt unter Einfügung der erforderlichen Isolation einen daran festgespannten, seitlich vorspringenden Arm q, der mit einer Hülse zur Aufnahme eines Zugseiles 0 und einer Klemme zum Befestigen der Leitungsschnur η versehen ist. Die Leitungsschnur m ist mit dem unteren Ende der Tragstange ä, verbunden. In the drawing, the current collector according to the invention is shown in FIG. 1 in a side view and in FIG. 2 in a section along the line 2-2 in FIG. The rollers c running on the upper contact wire i are connected to one another in a known manner by yoke α. The support rod d, which is bent to one side according to FIG. 2, passes through a laterally projecting arm q clamped to it, with the addition of the required insulation, which is provided with a sleeve for receiving a tension cable 0 and a clamp for attaching the line cord η. The line cord m is connected to the lower end of the support rod ä.
Der Arm q trägt einen Stift r, auf dem lose drehbar zwei Arme s und t sitzen, die durch eine Feder u miteinander verbunden sind. Jeder Arm trägt an seinem oberen freien Ende einen Schleifbügel v, der in bekannter Weise aus Weichmetall, z. B. Aluminium, ausgeführt und vorzugsweise nach einer Kugelfläche gekrümmt wird, deren Mittelpunkt im oberen Fahrdraht i liegt. An beiden Enden w wird der Schleifbügel vorzugsweise hakenförmig nach innen umgebogen,The arm q carries a pin r on which two arms s and t sit loosely rotatable and are connected to one another by a spring u. Each arm carries at its upper free end a grinding bow v, which is made in a known manner from soft metal, for. B. aluminum, executed and preferably curved according to a spherical surface, the center of which is in the upper contact wire i . At both ends w , the sanding hanger is bent inwards, preferably in the shape of a hook,
um zu verhindern, daß er entgleisen kann, wenn der Stromabnehmer seitlich ausgeschwenkt wird.to prevent it from derailing when the pantograph is swung out to the side will.
Die Einrichtung wirkt in der Weise, daß in jeder vorkommenden Lage des Stromabnehmers beide Schleifbügel υ von unten gegen den unteren Fahrdraht I mit Hilfe der Feder u angepreßt werden, und die Feder u gestattet auch, die Bügel ν von Hand soThe device acts in such a way that in each occurrence position of the current collector both sliders υ from below against the lower traveling wire I with the help of the spring and pressed, and the spring and also allows the brackets by hand so ν
to weit zu spreizen, daß der Stromabnehmer von der Fahrleitung abgenommen werden kann.to spread wide that the pantograph can be removed from the contact line can.
In seiner Arbeitslage gemäß Fig. 2 gestattet der Bügel ohne Erhöhung des Reibungsdruckes ein Ausschwenken des Stromabnehmers nach beiden Seiten um die halbe Länge der Bügel v. In its working position according to FIG. 2, the bracket allows the pantograph to be pivoted out to both sides by half the length of the bracket v without increasing the frictional pressure.
