Abstract

The tubular sections are for handle bars and foot rests of motorcycles or similar vehicles. The interior of the tubes is filled partly or completely with a non-metallic dampener material e.g. soft synthetic foam. The material reduces vibration, and provides a rust-proofing. The arrangement is used particularly in the tubes comprising the frame in the engine region, and is injected after the frame has been constructed via suitable apertures. Where weight is not critical a glass fibre laminate may be used, and is partic. useful for metals such as aluminium which are prone to fatigue failure.

Description

Rohrteile für Lenkstangen und Fußrastenrahmen von Motorrädern und anderen einspurigen Motorfahrzeugen Die Erfindung betrifft Rohrteile für Lenkstangen und Fußrastenrahmen von Motorrädern und anderen einspurigen Motorfahrzeugen. Tubular parts for handlebars and footrest frames of motorcycles and Other Single Track Motor Vehicles The invention relates to tubular members for handlebars and footrest frames of motorcycles and other single-track motor vehicles.

Es sind Konstruktionen von Trag- und anderen Motorradteilen aus Metallrohren bekannt, bei denen die Rohre vorzugsweise aus Duralumin, Titan oder anderen Metallen entweder nahtlos oder geschweißt sind und einen runden, rechteckigen oder anderen Querschnitt aufweisen. Das Rohrinnere wird in der Regel in dem ursprünglichen Ferti-. gungszustand manchmal durch Lack oder ein flüssiges Rostschutzmittel geschützt. Es ist auch eine Konstruktion bekannt, bei welcher der Innenraum der Rahmenrohre bzw. dessen Teile mit Öl ausgefüllt werden und als Ö1-behälter dienen. Bei Rahmenkonstruktionen und anderen Tragteilen einspuriger Motorfahrzeuge werden auch nichtmetallische Werkstoffe wie z. B. Glasfaserlaminate und Kunststoffe verwendet.There are constructions of supporting and other motorcycle parts made of metal tubes known, in which the tubes are preferably made of duralumin, titanium or other metals either seamless or welded and one round, rectangular or other Have cross-section. The inside of the pipe is usually in the original finished. condition sometimes protected by varnish or a liquid anti-rust agent. It is also one Construction known in which the interior of the frame tubes or its parts be filled with oil and serve as an oil container. With frame constructions and other supporting parts of single-track motor vehicles are also non-metallic materials such as B. fiberglass laminates and plastics are used.

Nachteilig bei den bisher bekannten metallischen Konstruktionen ist das leichte Anschwingen der Rahmen-, Lenkstangen- und der Fußrastenrohre, die in Zusammenhang mit den Motorschwingungen entsteht. Metallische Werkstoffe übertragen die Motorschwingungen weitgehend ungedämpft auf den Rahmen, wobei unerwünschte wenig gedämpfte Resonanzerscheinungen auftreten.A disadvantage of the previously known metallic constructions the slight oscillation of the frame, handlebar and footrest tubes, which are in There is a connection with the engine vibrations. Transferring metallic materials the engine vibrations largely undamped on the frame, with little undesirable dampened resonance phenomena occur.

Daraus ergeben sich z. B. Vibrationen'der Lenkstange, der Fußrasten und anderer Fahrzeugteile, welche die Fahrt unangenehm gestalten und häufig zu Beschädigungen der Instrumente, Lockerungen der Verbindungselemente und zu Rissen an einzelnen Bauteilen und der TragkonstruMtonen führen.This results in z. B. Vibrationen'der handlebar, the footrests and other vehicle parts that make the journey uncomfortable and often cause damage the instruments, loosening of the fasteners and cracks on individual ones Components and the supporting structure.

Rohrkonstruktionen aus nichtmetallischen Werkstoffen sind aufwendig und wenig starr und fest.Pipe constructions made from non-metallic materials are complex and not very rigid and firm.

Aufgabe der Erfindung ist es, die Schwingungsdämpfung von stabilen und fahrsicheren Rohrkonstruktionen von einspurigen Kraftfahrzeugen mit geringem technischen Aufwand wesentlich zu verbessern.The object of the invention is to reduce the vibration damping of stable and safe to drive tubular structures of single-track motor vehicles with little to significantly improve technical effort.

Diese Aufgabe wird dadurch gelöst, daß das Innere der Metallrohre von Rahmen oder anderen Teilen mit einem nichtmetallischem Dämpfungswerkstoff gefüllt sind.This object is achieved in that the interior of the Metal pipes of frames or other parts filled with a non-metallic damping material are.

Ein Vorteil der Erfindung besteht darin, daß die große Steifigkeit und Festigkeit der Metallkonstruktion erhalten bleibt und außerdem noch die Schwingung wirksam gedämpft wird. Bei Verwendung eines Rahmen-Vorderteiles aus Metallrohren, deren Inneres mit dem Dämpfungsmittel ausgefüllt ist, wird ein unerwünschtes Anschwingen des oberen Rahmenteiles wirksam gemindert. Durch Verwendung eines erz in dungsgemäßen Rohres als Lenkstange eines Motorrades wird deren Schwingung ebenfalls herabgesetzt und das Fahrgefühl über den gesamten Drehzahlbereich des Motors wesentlich verbessert. Als Dämpfungsmaterial eignet sich z. B.An advantage of the invention is that the great rigidity and strength of the metal construction is preserved and also the vibration is effectively damped. When using a frame front part made of metal tubes, the interior of which is filled with the damping means, an undesirable oscillation is generated of the upper frame part effectively reduced. By using an ore in the proper Tube as the handlebar of a motorcycle, their vibration is also reduced and the driving experience is significantly improved over the entire speed range of the engine. As a damping material, for. B.

weicher Schaumstoff mit hohen Dämpfungseigenschaften, der einfach in das Innere der Rohre gegossen werden kann und sehr leicht ist. Ein weiterer Vorteil der erfindungsgemäßen Konstruktion ist der vollkommene Rostschutz des Rohrinneren.soft foam with high cushioning properties that is easy can be poured into the interior of the tubes and is very light. Another advantage the construction according to the invention is the complete rust protection of the pipe interior.

Ein praktisches Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung als Seitenansicht des Motorradrahmens dargestellt.A practical embodiment of the subject invention is shown in the drawing as a side view of the motorcycle frame.

Der Metallrahmen 1 bildet den Konstruktionshauptteil des ganzen Fahrzeuges. Im unteren Rahmenteil ist das vordere Befestigungsstück 2 und das hintere Befestigungsstück 3 für den Motor angebracht. Das von dem vorderen Befestigungsstück 2 zum Rahmenkopf 5 führende Metallrohr 4 ist innen mit nichtmetallischem Werkstoff 7 ausgefüllt. Beim Fahrbetrieb entstehen Schwingungen, die vom Motor über die Befestigungsstücke2, 3 und ggf. die Achsen auf den Rahmen 1 übertragen werden. Das Anschwingen des Kopfes 5 wird durch die Dämpfungsfüllung sehr eingeschränkt, da die Schwingungen durch den nichtmetallischen geschäumten Werkstoff 7 im Innern 6 des Metallrohres 4 gedämpft werden.The metal frame 1 forms the main structural part of the entire vehicle. In the lower frame part is the front fastening piece 2 and the rear fastening piece 3 attached for the engine. That from the front attachment piece 2 to the frame head 5 leading metal pipe 4 is filled with non-metallic material 7 on the inside. When driving, vibrations occur that are transmitted from the engine via the mounting pieces2, 3 and possibly the axes on the Frame 1 are transmitted. The swing of the head 5 is very limited by the damping filling, since the vibrations by the non-metallic foamed material 7 in the interior 6 of the metal pipe 4 can be attenuated.
