Description

Rahmen, insbesondere für Kraftfahrzeuge Die Erfindung bezieht sich auf einen Fahrzeugrahmen mit als Hohlträger ausgebildeten Rahmenlängsträgern, die aus einstückigen Blechplatten mit einer in der Längsrichtung durchlaufenden Schweißnaht hergestellt sind, bei denen die Enden der Blechplatten über die in der neutralen Zone und im Mantel des Trägerprofils liegenden: Schweißnaht nach der Rahmenmitte hin herausgezogen sind.Frame, especially for motor vehicles The invention relates to on a vehicle frame with frame side members designed as hollow beams, which made of one-piece sheet metal with a weld seam running in the longitudinal direction are made in which the ends of the sheet metal plates over those in the neutral Zone and lying in the jacket of the support profile: weld seam towards the center of the frame are pulled out.

Beim Gegenstand des Patents 707 752 bilden die über die Schweißnaht herausgezogenen Blechenden ein Verbindungsblech für andere Rahmenteile. Die Erfindung gestaltet diesen Gegenstand in der Weise fort, daß die über die Schweißnähte herausgezogenen Blechenden eine gemeinsame, beide Rahmenlängsträger miteinander verbindende Bodenplatte bilden. Dadurch ist es möglich, einen Fahrzeugrahmen mit zwei geschlossenen Rahmenlängsträgern aus einer einzigen Blechplatte zu fertigen und auf diese Weise mit den einfachsten Mittelur eine verwindungssteifa Plattform für die Wagenaufbauten zu schaffen. Die Bodenplatte ist hierbei durch beide längs laufende Schweißnähte so fest mit dien Rahmenlängsträgern vereinigt, daß sich die Anbringung besonderer Versteifungsträgei erübrigt. Derartige Rahmen sind, insbesondere für Kleinfahrzeuge, von großer Einfachheit und Billigkeit.In the subject matter of patent 707 752 , the sheet metal ends pulled out via the weld seam form a connecting sheet for other frame parts. The invention develops this subject further in such a way that the sheet metal ends pulled out over the weld seams form a common base plate which connects both frame side members to one another. This makes it possible to manufacture a vehicle frame with two closed frame side members from a single sheet metal plate and in this way to create a torsion-resistant platform for the car bodies with the simplest means. The base plate is so firmly united with the frame side members by both longitudinal weld seams that the attachment of special stiffening struts is unnecessary. Such frames are, especially for small vehicles, of great simplicity and cheapness.

Es sind aus einer Blechplatte hergestellte Rahmen bekannt, deren Ränder zur Bildung tragfähiger Längs- und Querträger winkelig abgebogen sind. Die abgebogenen Plattenenden bilden in diesem Fall nur offene Bahmenträger von beschränkter Verwindungsfähigkeit;derartige Rahmen müssen daher durch besondere hochstetige Querträger versteift werden, wobei die Vorteile der einfachen Rahmenbauart verlorengehen.There are known frames made from a sheet metal plate, the edges of which are bent at an angle to form load-bearing longitudinal and transverse beams. The bent ones In this case, panel ends only form open web supports with limited torsional flexibility; Frames must therefore be stiffened by special high-continuity cross members, whereby the advantages of the simple frame design are lost.

Der Gegenstand der Erfindung ist auf der Zeichnung näher veranschaulicht. Diese zeigt ,den Querschnitt durch einen Rahmen.The subject matter of the invention is illustrated in more detail in the drawing. This shows the cross section through a frame.

Eine Blechplatte ist an beiden Längsseiten eingerollt und durch längs laufende Schweißnähte f zu rohrförmigen Längsträgern e geschlossen. Die über die Schweißnähte f hinausgezogenen Blechenden bilden eine gemeinsame, beide Längsträger c miteinander verbindende Bodenplatte g. Diese liegt, ebenso wie die Schweißnähte/, in der neutralen Zonex, x der Längsträgere. In die Bodenplatte g sind zweckmäßig Versteifungssiggen eingepreßt. Wenn nötig, kann die Blechplatte g auch an der Vorder- und Hinterseite des Rahmens zur Bildung von. Querträgern eingerollt werden. Die Bodenplatte g kann selbstverständlich auch mit hinpressungen zur Aufnahme der Längstreibwelle, des Werkzeugkastens o.,dgl. versehen werden.A sheet metal plate is rolled up on both long sides and closed by longitudinal weld seams f to form tubular longitudinal members e. The sheet metal ends pulled out over the weld seams f form a common base plate g which connects the two longitudinal members c to one another. Like the weld seams /, this lies in the neutral zone x, x of the longitudinal beam e. Stiffening seals are expediently pressed into the base plate g. If necessary, the sheet metal plate g can also be attached to the front and rear of the frame to form. Cross members are rolled up. The base plate g can of course also be pressed in to accommodate the longitudinal drive shaft, the tool box or the like. be provided.
