Description
Die Erfindung bezieht sich auf eine Laufrolle für Handfahrzeuge, bei welcher der Quersteg der schwenkbar gelagerten Rollenstützgabel sich gegen einen Puffer aus nachgiebigem Material stützt.The invention relates to a roller for hand vehicles, in which the Crossbar of the pivoted roller support fork against a buffer made of flexible Material supports.
Bei leichten Handfahrzeugen ist oft ein möglichst erschütterungsfreier Lauf bedingt. Dieser wird durch federnd angeordnete Rollen oder durch eine nachgiebig abgestützte, drehbar angeordnete Rollenstützgabel erreicht. Bei den bekannten Bauarten sind die Rollenstützgabeln so angeordnet, daß die Nachgiebigkeit durch Federn in Verbindung mit einer Achse als Drehpunkt bewirkt wird. Die Federn haben die Nachteile, daß bei zunehmender Belastung die Nachgiebigkeit sinkt, ferner brechen oder erlahmen diese häufig. Weiter ist bekannt, daß die Rollenstützgabeln durch eine Achse drehbar ge- lagert und auf einem Puffer aus nachgiebigem Material federnd abgestützt sind. Diese Anordnung bewirkt eine Federung in der Schwenkrichtung der Rollenstützgabel zum Puffer, während in der Gegenrichtung keine Federung möglich ist.In the case of light hand vehicles, it is often necessary to run with as little vibration as possible. This can be rotated by means of resiliently arranged rollers or a resiliently supported one arranged roller support fork reached. In the known types, the roller support forks are arranged so that the resilience is brought about by springs in connection with an axle as a fulcrum. the Springs have the disadvantages that the flexibility decreases with increasing load, and they also break or weaken frequently. It is also known that the roller support forks can be rotated by an axis. and are resiliently supported on a buffer made of flexible material. These Arrangement causes a suspension in the pivoting direction of the roller support fork to the buffer, while none in the opposite direction Suspension is possible.
Im Gegensatz zu den bekannten Bauarten besteht das Neue der Erfindung darin, daß der Quersteg der Rollenstützgabel schwenkbar zwischen zwei Puffern gelagert ist.In contrast to the known types, the novelty of the invention is that the crossbar of the roller support fork is pivotably mounted between two buffers.
In der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigtIn the drawing, the subject of the invention is shown, namely shows
Abb. ι die Rollenstützgabel in unbelastetem Zustande im Schnitt undFig. Ι the roller support fork in the unloaded state in section and
Abb. 2 im Belastungszustand im Schnitt.Fig. 2 in the loaded state in section.
Der Quersteg d der Rollenstützgabel α ist 3ü schwenkbar zwischen zwei Puffern aus nachgiebigem Material, z. B. Gummi, nach zwei Seiten abgestützt. Das Ganze wird durch eine Kapsel c allseitig umschlossen, wodurch verhindert wird, daß die Puffer b bei Belastung seitlich ausweichen.The crossbar d of the roller support fork α is 3ü pivotable between two buffers made of flexible material, for. B. rubber, supported on two sides. The whole is enclosed on all sides by a capsule c , which prevents the buffers b from giving way to the side when loaded.
Bei einer Belastung schwenkt die Rollenstützgabel α aus und der Quersteg d wird zwischen den Puffern & abgestützt (Abb. 2). Durch die Nachgiebigkeit des durch die Kapsei c umschlossenen Puffermaterials wird eine stets gleichförmige Federung bewirkt.When a load is applied, the roller support fork α swivels out and the crossbar d is supported between the buffers & (Fig. 2). The resilience of the buffer material enclosed by the capsule c always causes uniform resilience.
Die Bauart ist so gewählt, daß der Quersteg d mit den Puffern b einen schwenkbaren Stützpunkt für die Laufrolle bildet und ein Drehpunkt durch eine Achse nicht erforderlich ist.The design is chosen so that the crossbar d with the buffers b forms a pivotable support point for the roller and a pivot point through an axis is not required.
