Description

Beschreibung Scherenstromabnehmer elektrisch betriebener Fahrzeuge mit fast unterschiedlosem Auf- und Abwärtsanpressdruck. Die bisher im Betrieb befindlichen Scherenstromabnehmer elektrisch betriebener Fahrzeuge weisen einen starken unterschiedlichen Fahr- drahtanpressdruck zwischen Auf-und Abwärtsbewegung auf. Hierdnrch entstehen im Fährbetrieb folgende Nachteile : Bei fallender Fahrdraht- höhe ird der Stromabnehmer abwärts gedrückt und dor Anpressdmck verrös&ert sieh. Die Folge dieses durch die Abwärtsbewegung vernr- « sachten erhöhten Anpressdruckes ist ein erhöhter Tersehleiss am Schleifstück und Fahrdraht* Steigt die Fahrdrahthohe stark ant z. B. nach Durchfahren einer Unterführuns : so tritt bei schneller Fahrge- schwindigkeit sehr oft der Fall ein, dass der Stromabnehmer kurzzei- tla LiC} hrdraht mer ols tig nicht am Fahrdraht liegte weil der Stromabnehmer infolge der durch die Lagerreibng entstandenen Trägheit nicht schnell genug wie- der steigt. Es entsteht ein kurzzeitiges Abreissen wodurch Unterbre- tachen, chungsfnnken entstehen die ebenfalls Schleifstück und Fahrdraht ab- nutzend angreifen und ansserdem unliebsame Enndfunkstörungen verur- sachen. Die Überwindung dieser-ira. heit an dem Stromabnehmer ecka Erie- lun eines verminderten jedoch fast gleichbleibenaen Anpressdruokes bei Auf-und Abwärtsbewegungen ist der Segenstand unserer Erfindung. Dieses Ziel vjird ohne irgendwelche ma&slioh-en."nerungen an den bis- herigen Scherenstromabnehaern dadurch erreichte dass anstelle der bisher verwandten Buchsen raumsparende Nadelbuchsen verwandt werden. Der bisher an allen Scherenstromabnehmern auftretende unterschied- liche Anpressdru. ck bei Auf-und Abwärtsbewegungen von 1, 5-2 km wird hierdurch auf wenige Gramm reduzierty wodurch einmal ein elasti- scher und reaktionsschnelles Anliegen des Stromabnehmers am Fahr- draht gewährleistet und zum anderen ein Funke eis&en nicht mehr her- vorGerufen wird. Hinzu tritt noch, dss der Anpressdruck um die durch den Reibungswiderstand entstandene Differenz bei Auf- und Abwårtsbe- wegung von 1 1/2-2 kg gemindert werden kann, wodurch eine Schonmg des Materials bewirkt und eine längere Lebensdauer gewährleistet wird. description Pantographs for electrically operated vehicles with almost indistinguishable upward and downward pressure. The pantographs currently in operation are electrical operated vehicles show a strong different driving wire contact pressure between upward and downward movement. Here no the following disadvantages arise in ferry operation: When the contact wire height, the pantograph is pressed down and the pressure is applied red & ert see. The consequence of this, due to the downward movement, gently increased contact pressure is an increased Tersehleiss on the Contact strip and contact wire * If the contact wire height rises sharply, e.g. B. after driving through an underpass: speed, it is very often the case that the pantograph is briefly tla LiC} hrdraht mer ols tig was not on the contact wire because the pantograph as a result of the the inertia caused by the bearing friction does not return quickly enough. that rises.
