Description

Die Erfindung betrifft eine Ausbildung der Vorderradgabel für Motorroller und ähnliche Fahrzeuge, die mit einer Doppelteleskop-Abfederung versehen sind.The invention relates to a design of the front fork for scooters and similar vehicles that are provided with a double telescopic suspension.

Die bekannten Abfederungen der Vorderradgabeln sind meist so ausgebildet, äaß sie symmetrisch zu beiden Seiten der Steuersäule befestigt sind, wodurch der Radwechsel nur nach Demontage der Vorderachse möglich ist.The well-known suspension of the front forks are usually designed in such a way that They are attached symmetrically on both sides of the steering column, whereby the A wheel change is only possible after dismantling the front axle.

Nach der Erfindung wird eine .Ausbildung der Vorderachse vorgeschlagen, bei der eine Doppelteleskop-Abfederung vorhanden ,und der Radwechsel in einfachster Weise ohne Entfernung der Vorderachse möglich ist, wie es für einen Motorroller besonders vorteilhaft ist.According to the invention, a training of the front axle is proposed, in which a double telescopic suspension is available, and the wheel change in the simplest possible way Way without removing the front axle is possible, as it is for a scooter is particularly advantageous.

Die Teleskoprohre sind erfindungsgemäß auf einer Seite an der Steuersäule und am Laufrad angeordnet. Sie sind hintereinander an einem Lenker der Steuersäule befestigt. Die Teleskoprohre sind in einem Winkel zur Radebene angeordnet, so daß der Hebelarm vom Bodenberührungspunkt des Rades bis zum Schnittpunkt der Mittellinie der Teleskoprohre mit dem Boden kleiner ist, als wenn das Teleskoprohr mit dem nötigen Abstand vom Laufrad parallel zur Mitte des Laufrades angeordnet ist.According to the invention, the telescopic tubes are on one side of the control column and arranged on the impeller. They are one behind the other on a handlebar of the control column attached. The telescopic tubes are arranged at an angle to the wheel plane, so that the lever arm from the ground contact point of the wheel to the intersection of the center line the telescopic tube with the bottom is smaller than when the telescopic tube with the necessary Distance from the impeller is arranged parallel to the center of the impeller.

Weiter ist die Steuersäule zur Radmitte außermittig zwischen Radmitte und den Teleskoprohren angeordnet, damit beim Fahren ein Gegengewicht zum Gewicht der einseitigen Teleskopgabel vorhanden ist und damit das einseitige Gewicht, das durch die einseitige Anordnung der Teleskoprohre entsteht, aufgehoben ist und beim Geradeausfahren keine seitlichen, das Vorderrad belastenden Momente eintreten.Furthermore, the steering column is off-center to the wheel center between the wheel center and the telescopic tubes arranged to counterbalance the weight when driving the one-sided telescopic fork is present and thus the one-sided weight that arises due to the one-sided arrangement of the telescopic tubes, is lifted and at Driving straight ahead, there are no lateral moments that put a strain on the front wheel.

Die außermittige Anordnung der Steuersäule zur Radmitte kann auch zu der freien Radseite hin erfolgen, wenn dieses durch die Winkelstellung der Teleskoprohre erforderlich ist.The off-center arrangement of the steering column to the wheel center can also to the free wheel side if this is done by the angular position of the telescopic tubes is required.

Zwischen den Teleskoprohren ist erfindungsgemäß eine Verbindungsbrücke befestigt, um die Verdrehsteifigkeit zwischen den Teleskopen zu gewährleisten. Die Brücke dient dabei gleichzeitig als Anschlag für die Federung. , In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt; es zeigt Abb. i eine Ansicht und Abb. 2 eine Seitenansicht. Das Vorderrad a ist einseitig an den hintereinander angebrachten Doppelteleskoprohren b, c gelagert. Die Teleskoprohre b, c sind an dem Lenker d befestigt, der mit der Steuersäule e verbunden ist. Um die durch die einseitige Anordnung des Doppelteleskops beim Fahren entstehenden Momente auszugleichen, sind die Doppelteleskoprohre b, c in einem Winkel f zur Radebene angeordnet. Weiter ist die Steuersäule e zur Radmitte außermittig um den Betrag g versetzt gelagert. Sie ist entweder zwischen Radmitte und den Teleskoprohren angeordnet oder zu der freien Seite des Rades versetzt, um beim Fahren die das Vorderrad durch die einseitige Anordnung belastenden Momente auszugleichen. Zwischen den Teleskoprohren b, c ist die Verbindungsbrücke h zur Erzielung der Verdrehsteifigkeit befestigt. Sie dient gleichzeitig als Begrenzung der Federung für die Anschläge i, k. According to the invention, a connecting bridge is fastened between the telescopic tubes in order to ensure the torsional rigidity between the telescopes. The bridge also serves as a stop for the suspension. In the drawing, the subject matter of the invention is shown in an exemplary embodiment; FIG. 1 shows a view and FIG. 2 shows a side view. The front wheel a is mounted on one side on the double telescopic tubes b, c attached one behind the other. The telescopic tubes b, c are attached to the handlebar d , which is connected to the control column e. In order to compensate for the moments caused by the one-sided arrangement of the double telescope when driving, the double telescopic tubes b, c are arranged at an angle f to the wheel plane. Furthermore, the control column e is offset from the center of the wheel by the amount g. It is either arranged between the center of the wheel and the telescopic tubes or offset to the free side of the wheel in order to compensate for the moments stressing the front wheel due to the one-sided arrangement when driving. The connecting bridge h is attached between the telescopic tubes b, c to achieve torsional rigidity. It also serves as a limitation of the suspension for the attacks i, k.
