Description

Die Anhängewagen der Straßenbahn sind oft mit Solenoidbremsen ausgerüstet. Diese bestehen aus einem das Solenoid und seinen Anker enthaltenden Gehäuse, durch dessen Wand eine zur Betätigung der Bremse dienende Stange mittels Stopfbüchse herausgeführt ist. Diese Abdichtung für die Wanddurchführung des Gestänges ist bei dem muhen Betrieb einem raschen Verschleiß unterworfen, weil Schmutz, Staub, Feuchtigkeit zu der Stopfbüchse gelangen können. Bei Schadhaftwerden der Dichtung gelangt Schmutz in das empfindliche Solenoid und ruft dadurch Betriebsstörungen hervor.The tram trailers are often equipped with solenoid brakes. These consist of a housing containing the solenoid and its armature the wall of which a rod used to actuate the brake is led out by means of a stuffing box is. This seal for the wall duct of the rod is in the low operation subject to rapid wear because of dirt, dust, moisture to the stuffing box can get. If the seal becomes damaged, dirt gets into the sensitive one Solenoid and thereby causes malfunctions.

Die Erfindung hat die Aufgabe, diese Mängel zu beseitigen. Erfindungsgemäß ist der Wanddurchführung des Gestänges ein teleskopartiger Rohrzug vorgeschaltet, dessen erstes Glied mit dem Gestänge und dessen letztes Glied mit dem Gehäuse verbunden ist.The invention aims to remedy these shortcomings. According to the invention a telescopic pipe section is connected upstream of the wall duct of the boom, whose first link is connected to the linkage and whose last link is connected to the housing is.

Die Erfindung wird an Hand der Zeichnung näher erläutert. Von dem Solenoidgehäuse ist nur eine Gehäusekappe r, durch deren Boden mittels einer Stopfbüchse 2 eine Stange 3 herausgeführt ist, dargestellt. An der Stirnseite der Kappe ist ein erstes Rohrstück 4 mittels eines Flansches 5o befestigt, in dem sich ein zweites Rohrstück 5 verschieben kann. An dem Stangenkopf 6 ist ein drittes Rohrstück 7 dicht abschließend angebracht, das sich in dem Rohrstück 5 verschieben kann. Die ineinandergreifenden Enden der Rohrstücke sind auf- bzw. eingebördelt.The invention is explained in more detail with reference to the drawing. Of the Solenoid housing is just a housing cap r, through the bottom by means of a stuffing box 2, a rod 3 is led out, is shown. At the front of the cap is a first pipe section 4 fastened by means of a flange 5o, in which a second Pipe section 5 can move. A third pipe section 7 is sealed against the rod head 6 finally attached, which can move in the pipe section 5. The interlocking The ends of the pipe sections are flanged or crimped.

Bei ausgefahrener Stange 3 ist der Rohrzug 4, 5, 7 auseinandergezogen, bei eingefahrener Stange schieben sich die Rohrstücke ineinander. Dieser teleskopartige Rohrzug bildet eine Vorkammer für die Stopfbüchse 2 und verhindert bzw. erschwert das Eindringen von Fremdstoffen, Spritzwasser usw. in die Stopfbüchse 2. Dadurch wird deren Lebensdauer und damit die Betriebssicherheit des Solenoids wesentlich erhöht.When the rod 3 is extended, the tube 4, 5, 7 is pulled apart, When the rod is retracted, the pipe sections slide into one another. This telescopic The pipe section forms an antechamber for the stuffing box 2 and prevents or complicates it the ingress of foreign matter, splash water, etc. into the stuffing box 2. This their service life and thus the operational reliability of the solenoid becomes essential elevated.
