Description

Vorderradgabel für Motorräder Die Erfindung betrifft eine Vorderradgabel für Motorräder, die aus zwei in den einzelnen Stäben U-förmigen Querschnitt aufweisenden, aus Blech gepreßten Seitenrahmen hergestellt ist.Front fork for motorcycles The invention relates to a front fork for motorcycles that consist of two U-shaped cross-sections in the individual rods, is made of pressed sheet metal side frame.

Das Neue der Erfindung besteht darin, daß die Seitenrahmen durch gleichfalls aus Blech gepreßte Einsatzstücke mit U-förmigem Querschnitt verstärkt und durch weitere aus Blech gepreßte Teile von U- oder kastenförmigem Querschnitt miteinander verbunden sind.The novelty of the invention is that the side frame reinforced by also pressed from sheet metal insert pieces with U-shaped cross section and are connected together by further pressed from sheet metal parts of U-shaped or box-shaped cross-section.

Der Gegenstand der Erfindung zeichnet sich gegenüber den üblichen, aus Rohren hergestellten Gabeln bei erhöhter Widerstandsfähigkeit durch einfachere und billigere Herstellung und geringeres Gewicht aus.The object of the invention is distinguished from the usual, Forks made from tubes with increased resistance due to simpler ones and cheaper to manufacture and lighter in weight.

Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes veranschaulicht. Abb. i zeigt einen der U-Profilrahmen, auf die nach innen gerichtete Seite gesehen, also in einem Schnitt nach der Linie A-B von Abb. a, wobei die beiderseits der Abb. i angegebenen Schnittfiguren Schnitte nach den Linien C-D bzw. E-F von Abb. i darstellen.An embodiment of the subject matter of the invention is illustrated in the drawing. Fig. I shows one of the U-profile frames, seen on the inwardly directed side, i.e. in a section along the line AB from Fig. A, whereby the sectional figures given on both sides of Fig .i represent.

Abb. 2 ist eine Aufsicht.Fig. 2 is a top view.

In den Nabenteil und den unteren Schenkel des in U-Profilform gepreßten Seitenrahmens ct sind zur Verstärkung entsprechend geformte U-Profilbleche b, c eingesetzt. Ein weiteres in den oberen Schenkel des Seitenrahmens a eingesetztes U-Profilblech d ist durch einen gleichfalls U-profilförmigen oder auch allseitig geschlossenen (kastenförmigen) Blechkörper c mit einem gleichen U-Profilblech f des anderen Seitenrahmens g verbunden.In the hub part and the lower leg of the side frame ct, which is pressed into a U-profile shape, correspondingly shaped U-profile sheets b, c are used for reinforcement. Another U-shaped sheet metal d inserted into the upper leg of the side frame a is connected to an identical U-shaped sheet metal f of the other side frame g by a likewise U-shaped or also closed (box-shaped) sheet metal body c.

Die U-Profilbleche c, d, e, f sind zur Verringerung des Gewichtes der Gabel, wie aus Abb. 2 ersichtlich ist, mit kreisförmigen Durchbrechungen h versehen.The U-profile sheets c, d, e, f are provided with circular openings h to reduce the weight of the fork, as can be seen from Fig. 2.

Verbindungsstege e der angegebenen Art können zur Erhöhung der Festigkeit in beliebig großer Anzahl vorgesehen sein.Connecting webs e of the specified type can increase the strength be provided in any large number.
