Description
Die Erfindung bezieht sich, auf eine Einrichtung' zum Abziehen von Faihrzeugradreifen von der Felge, die aus. einem, die Felge mit dem Reifen aufnehmenden Fuß und einer achsgerecht hierzu aufragenden Säulei mit einem von; dieser aufgenommenen:, oiederschrauibbaren Tragarm und; an diesem angelenkten Abdruckwerkzeugen bestehen. Bei diesen Einrichtungen ist es bekannt, die Abdruckwerkzeuge: exzentrisch an. dem Tragarm anzulenken, so daß sie unter axialer Druckbelastung gegen die Säule einschwenken und dabei ita dien Spalt zwischen dem Felgenrand und dem Reifenwulst eintreten. Der Einschwenkweg des das eigentliche Werkzeug tragenden Armes ist dabei durch einen verstellbaren Endanschlag begrenzt, der als Schraubbolzen ausgebildet und von. einer Gewindemuffe des Tragarmes aufgenommen ist. Das Einschwenken der die Werkzeuge tragenden Arme erfolgt dabei lediglich unter dem Gegend druck des Reifens, auf den die Werkzeuge· mit dem Tragarm, niedergeschraubt werden,.The invention relates to 'a device' for removing vehicle wheel tires from the Rim that out. one that receives the rim with the tire Foot and a pillar that rises up to the axis with one of; this recorded :, screwable support arm and; exist on this articulated impression tools. In these devices it is known that the impression tools: eccentrically on. to be linked to the support arm, so that they pivot under axial pressure load against the column and thereby serve ita Enter a gap between the rim edge and the tire bead. The pivoting path of the das the actual tool-carrying arm is limited by an adjustable end stop, designed as a screw bolt and from. one Threaded sleeve of the support arm is added. The swiveling in of those carrying the tools Arms is only done under the area pressure of the tire on which the tools · with the support arm, are screwed down.
Die Erfindung betrifft eine Ausbildung dieser Abzieheinrichtungen;, bei welcher die Einschwenkbewegung der Werkzeuge durch Federn unteres stützt wird. Erfindungsgemäß sind bei eiber Einrichtung zum: Abziehen vom Faihrzeugradreifen von. der Felge aus einem dtie Felge mit dem Reifen aufnehmenden; Fuß und. einer achsgerecht hierzu aufragenden!, abnehmbaren; Säule mit einem miederschraubbaren Tragarm und an, diesem: exzentrisch angelenkten Abdrückwerkzeugen,, die unter dem auf sie beim Auftreffen auf den Reifen einwirkenr den Axialdruck gegen, die Säule ein schwenkbar sind, die Schwenkarme der1 Abdirückwerkzeuge in Richtung des Einschwenkweges durch Federn gestützt. Die Federn sind dabei zweckmäßig zwischen einem die Ausschwenkendstellung der Abdrückwerkzeuge begrenzenden, einstellbaren; Anschlag und; einem festem Gegenlager für diesen, angeordnet. The invention relates to a design of these extractors; in which the pivoting movement of the tools is supported by springs lower. According to the invention, with a device for: pulling off the vehicle wheel tire from. the rim from a dtie rim with the tire receiving; Foot and. a detachable one that towers upright along the axis; Column with a screwable support arm and, on this: eccentrically articulated push-off tools, which act against the axial pressure on them when they hit the tire, the column can be swiveled, the swivel arms of the 1 push-off tools supported by springs in the direction of the pivoting path. The springs are expediently adjustable between an adjustable position that limits the pivoting end position of the push-off tools; Stop and; a fixed counter bearing for this, arranged.
Die Ausbildung ist nachstehend an, Hand derThe training below is at, hand of the
Zeichnung näher erläutert, die eine Ansicht des einen Endes des niederschraubbareni Tragarmes mit dem daran angelenkten Abdrückwerkzeug wiedergibt.Drawing explained in more detail, which is a view of one end of the niederschraubbareni support arm reproduces with the extraction tool attached to it.
Die Gesamteinirichtung besteht a,uis einem Auflagefuß für die den Reifen tragende Felge mit einer abnehmbaren, achsgereeiht zu dem Fuß aufragendem Spindelsäule, die einen durch Verdrehen gegen den Reifen, niiederschraubbaren, Tragarm! 1 aufnimmt. Der Tragarm i, der aus- zwei mit Abstand voneinander angeordneten Flacheisen besteht, ist an jedem Ende mit einer Mehrzahl von Löchern, 2 zur versetizbarem Aufnahme je eines Tragzapfens 3 versehen, an, denen die Lagerarme 4 für Abdrückscheiben 16 pendelnd aufgehängt sind. Jeder Lagerarm 4 hat zwei über die Anienkungsstelle nach außen (in bezug auf den Tragarm; 1) vorspringende GabelnasenS, 6, die mit Gewihdebohrungen 7, 8 zur verstellbaren Aufnahme von, Schraubbolzen 9, 10 versehen sind. Die Schraubbolzen: 9, 10 stehen über die Ober- bzw. Umterkante des Tragarmes l vor und nehmen hier je eine sich zwischen ihren Köpfen und dem Tragarm 1 abstützende Federkappe 11 bzw. 12 auf. Die Einstellung der Sehrauibbolzen; 9, 10 erfolgt durch an ihren; Köpfen vorgesehene Knebel 13, 14. Zwischen dem Kopf dies Bolzens io- und der Federkappe 12, die mit einer entsprechenden Aussparung versehen ist, ist auf dem Bolzenschaft eine Wickelfeder 15 angeordnet.The overall arrangement consists of a support foot for the rim carrying the tire with a detachable, axially aligned rim that rises above the foot Spindle column that can be screwed down by twisting it against the tire! 1 records. The support arm i, which consists of two flat irons arranged at a distance from one another, is at each end with a plurality of holes, 2 for versetizbarem receiving one each Support pin 3 is provided on which the bearing arms 4 for push-off disks 16 are suspended in a pendulous manner. Each bearing arm 4 has two outwards via the articulation point (with respect to the support arm; 1) protruding fork nosesS, 6, those with threaded holes 7, 8 for the adjustable reception of, screw bolts 9, 10 are provided. The bolts: 9, 10 are in front of the upper or Umterkante of the support arm l and each take one here spring cap 11 or 12 supported between their heads and the support arm 1. The setting the inspection bolt; 9, 10 takes place through an their; Heads provided toggles 13, 14. Between the head of this bolt io- and the spring cap 12, which is provided with a corresponding recess, is a coil spring 15 on the bolt shank arranged.
Diei beiden Schraubbolzeti, 9, 10 werden so eingestellt, daß die oberem Bolzen 9 die Einschwenkendstellung der Lagerarme 4 bestimmen, während die Schraubbolzen 10 und die durch sie vorspann^- baren Federn 15 die durch das Gewicht der Lagerarme 4 mit den Abdrückscheiben 16 bestimmte Ausschwenkendstellung festlegen. Die Federn; 15 gleichen somit dieses Gewicht mehr oder weniger aus und; begünstigen hierdurch die Einsrihwenkbewegung der Teile 4, 16 beim Auftreffen der Scheiben 16 auf einen Reifen.The two sets of screw bolts 9, 10 are adjusted so that that the upper bolt 9 determine the pivoting end position of the bearing arms 4 while the bolts 10 and the prestressing through them ^ - ble springs 15 determined by the weight of the bearing arms 4 with the forcing disks 16 Define the swing-out end position. The feathers; 15 thus more or less equal this weight off and; thereby favor the Einrihwenkbewegung of the parts 4, 16 when the discs 16 hit a tire.
