Description

Paralbl lenke r-S enkrecht führung. Parallel steering r-vertical guidance.

Es sind Lenker- und Parallellenkerführungen bekannt deren Drehpunkte mit geräuschdämpfenden, wartungsfreien Elementen (z.B. Metallgummibuchsen) versehen sind. Diese Lenker werden sehr oft in Form eines Parallelogramms zur Führung begrenzter Hub- oder Schiebewege benutzt. Durch das Ausschlagen der Lenker um den Festpunkt wird das zu führende Maschinenteil seitlich verschoben. Da dieses Verschieben zu seitlichen Schwingungen führt und andererseits sehr lange Lenker erfordert um die seitliche Verschiebung auf ein Minimum herab zu setzen, werden erfindungsgemäß zwei Möglichkeiten vorgeschlagen: 1.Uber den am Naschinengestell befestigten Drehpunkt eines jeden Lenkers ein Segment welches auf einer Stützfläche abrollt anzubringen. Hierdurch wird eine optimale Senkrechtführung erreicht, wobei die Lenker je nach Hubhöhe auf ein Minimum gekürzt werden können. Zweckmäßigerweise sollten die Segmente mit den Stützflächen durch einvulkanisierte Gummischichten verbunden werden, wodurch die im Drehpunkt befindliche Metallgummibuchse entfällt. siehe Abb. II Abb. I zeigt, daß4as zu führende Maschinenteil 1 an den Lenkern 2 geführt wird. Die Segmente 3 sind mit den Lenkern fest verbunden und stützen sich an den Flächen 4 die mithem Maschinengestell verbunden sind ab. Durch die Hubbewegung des Maschinenteiles 1 rollen die Segmente 3, dessen Radius der Länge der Lenker entspricht, auf den Stützflächen 4 ab, wodurch ein seitliches Verschieben des Maschinenteiles 1 vermieden wird. There are handlebar and parallel link guides whose pivot points are known provided with noise-dampening, maintenance-free elements (e.g. metal rubber bushes) are. These handlebars are very often limited in the form of a parallelogram for guidance Lifting or pushing paths used. By swinging the handlebars around the fixed point the machine part to be guided is shifted sideways. Because this is moving too leads to lateral vibrations and on the other hand requires very long handlebars According to the invention, reducing lateral displacement to a minimum becomes two Suggested options: 1. Via the pivot point attached to the machine frame of each link to attach a segment which rolls on a support surface. In this way an optimal vertical guidance is achieved, whereby the handlebars depending on Lifting height can be reduced to a minimum. Appropriately, the segments are connected to the support surfaces by vulcanized rubber layers, whereby the metal rubber bushing located in the pivot point is omitted. see Fig. II Fig. I shows that machine part 1 to be guided is guided on the arms 2. The segments 3 are firmly connected to the links and are supported on the surfaces 4 mithem Machine frame are connected from. By the lifting movement of the machine part 1, the segments 3, the radius of which corresponds to the length of the handlebars, roll onto the Support surfaces 4 from, whereby a lateral displacement of the machine part 1 is avoided will.

2. Wie aus Abb. III ersichtlich ist, werden bei diesem Vor -schlag keine glatten Segmente, sondern Zahnsegmente 3 aus geräuschdämpfendem waetungsfreien Material z.B. Kunststoff verwendet, die an einer Zahnstange 4 abrollen. In diesem Fall ist es erforderlich, daß das Maschinenteil 1 nach beiden Seiten hin abgestützt wird, es können aber wesentlich kürzere Lenker verwendet werden. Dieses kann bei großen Hubhöhen dazuführen, daß, wie Abb. IV zeigt, keine Zahnsegsegmente sondern Zahnräder zur Anwendung kommen.2. As can be seen from Fig. III, this proposal no smooth segments, but toothed segments 3 made of noise-dampening, maintenance-free Material e.g. plastic used, which roll on a rack 4. In this In this case, it is necessary that the machine part 1 is supported on both sides but much shorter handlebars can be used. This can be done at large lift heights lead to the fact that, as Fig. IV shows, no toothed segments but Gears come into use.
