Die Erfindung betrifft einen Rahmen für Motorzweiräder, der in seiner Bauart wesentlich von den verschiedenartigen bestehenden Motorradrahmen abweicht.The invention relates to a frame for motorcycles, which is essential in its design differs from the various existing motorcycle frames.
· Der Rahmen besteht aus zwei übereinander •liegenden aneinander stoßenden Trapezen und zwei am unteren Trapez anschließenden Dreiecken. · The frame consists of two trapezoids and two triangles adjoining the lower trapezoid.
Das eine Trapez ist auf der Zeichnung mit ίο a, b, c, d, das andere mit c, d, e,f bezeichnet. Das erste Dreieck trägt die Buchstaben d, e, g, das zweite d, h, g. One trapezoid is marked on the drawing with ίο a, b, c, d, the other with c, d, e, f . The first triangle bears the letters d, e, g, the second d, h, g.
Die Herstellung des Rahmens aus zwei Trapezen, und zwei Dreiecken bietet die Möglichkeit, alle Rohre im gleichen Winkel und Gegenwinkel zu legen.The manufacture of the frame from two trapezoids and two triangles offers the Possibility to lay all pipes at the same angle and opposite angle.
Ein weiteres Merkmal des Rahmens besteht in der Verlängerung des mittleren wagerechten Strebenrohrs c, d über die Mitte des Hinterrades hinaus, um auf diese Weise eine feste Brücke zur Aufnahme des verstellbaren Sattels zu erhalten. Hierdurch kommt gleichzeitig der Sattel über dem Hinterrade zu liegen und die obere Sattelfläche kann tiefer als das oberste wagerechte Rahmenrohr a, b angeordnet werden.Another feature of the frame is the extension of the central horizontal strut tube c, d beyond the center of the rear wheel in order to obtain a fixed bridge for receiving the adjustable saddle. As a result, the saddle comes to rest over the rear wheel at the same time and the upper saddle surface can be arranged lower than the uppermost horizontal frame tube a, b .
Durch diese Anordnung soll die SicherheitThis arrangement is intended to ensure safety
während der Fahrt erhöht und das Gewicht des Fahrers richtig über die Achse des Hinterrades gebracht werden, und soll, ohne die Möglichkeit des Mittretens zu verhindern, dem Fahrer ermöglicht werden, beim Ausstrecken der Beine mit den Füßen auf dem Boden zu stehen.while driving increases and the weight of the driver is correct on the axis of the Rear wheel, and should, without preventing the possibility of pedaling, enable the driver to stand with his feet on the ground while stretching out his legs.
Das Lenken des Motorfahrrades geschieht mittels eines am oberen Rahmenrohr a, b befestigten Lenkrades oder einer Lenkstange.The motorbike is steered by means of a steering wheel or a handlebar attached to the upper frame tube a, b.
