BeschreibungDescription
Teleskopartiges Zweiradfederungssystem mit besonders großem. Überlappungsbereich der ineinandergleitenden Rohre.Telescopic two-wheel suspension system with a particularly large overlap area of the tubes sliding into each other.
Stand der Technik.State of the art.
Bei herkömmlichen Pederungssystemen nach dem Teleskopprinzip ist die Überlappung der Rohre durch Unterbringung der Feder- und/oder Dämpfungssysteme in den ineinander gleitenden Rohren konstruktionsbedingt begrenzt. Durch den überlappungsfreien Abschnitt von der Radachse bis zum ersten abstützenden Gleitlager zwischen Tauchrohr und Standrohr bewirken auf das Rad einwirkende Torsions- und Stoßkräfte Abweichungen der Tauchrohrachse gegenüber der Standrohrachse. Diese Torsionsneigung wird üblicherweise durch vergrößerte Rohrquerschnitte kompensiert« .-· 'In conventional suspension systems based on the telescopic principle, the overlap of the tubes is limited by the design by accommodating the spring and/or damping systems in the tubes that slide into one another. Due to the non-overlapping section from the wheel axle to the first supporting plain bearing between the immersion tube and the standpipe, torsional and impact forces acting on the wheel cause deviations in the immersion tube axis compared to the standpipe axis. This tendency to torsion is usually compensated for by enlarged tube cross-sections.
Erfindunginvention
Eine verminderte Torsionsneigung bei gleichzeitig kleinen Rohrdurchmessern wird mit den Maßnahmen der Ansprüche 1-7 erreicht.A reduced tendency to torsion with simultaneously small pipe diameters is achieved with the measures of claims 1-7.
Weiterbildungen der ErfindungFurther developments of the invention
Die Ausgestaltung der Erfindung nach den Ansprüchen &Lgr;-£* mit zentral im Steuerkopf untergebrachten Dämpfungs- und/oder Federelement erlaubt durch einen oben am Steuerkopf angebrachten Verstellungsmechanismus (26) eine besonders einfache, evtl. während der Fahrt durchführbare Abstimmung der Federungseigenschaften. Da die Gleitlager bei dieser Ausführung besonders weit auseinander liegen können die Rohrquerschnitte entsprechend klein gewählt werden ohne Verlust der Torsionsfestigkeit.The design of the invention according to claims Λ-£* with a damping and/or spring element housed centrally in the steering head allows a particularly simple adjustment of the suspension properties, possibly carried out while driving, by means of an adjustment mechanism (26) mounted on the top of the steering head. Since the plain bearings in this design are particularly far apart, the tube cross-sections can be chosen to be correspondingly small without loss of torsional strength.
Zweiradfederung Blatt 4 Klaus Kramer-M. Darstellung der ErfindungTwo-wheel suspension sheet 4 Klaus Kramer-M. Description of the invention
Ein Ausführungsbeispiel der Erfindung wird an Hand der Figuren 1 bis &Iacgr;0 erläutert:An embodiment of the invention is explained with reference to Figures 1 to 60:
Pig. 1 zeigt eine perspektivische Ansicht eines Fahrrades mit den "beiden Teleskopgabel (27/28). Bei der Hinterradgabel (28), sind die Dämpfungselemente (22) zwischen der Querverbindung (H) der äußeren Rohre (4) und der Verbindung (16) der inneren Rohre angebracht. Das Feder- und/oder Dämpfungselement der Vorderradgabel (27) ist im G-abelschaftrohr untergebracht.Pig. 1 shows a perspective view of a bicycle with the two telescopic forks (27/28). In the rear fork (28), the damping elements (22) are mounted between the cross connection (H) of the outer tubes (4) and the connection (16) of the inner tubes. The spring and/or damping element of the front fork (27) is housed in the fork shaft.
Pig. 2 stellt eine Funktionsskizze einer Vorderradfedergabel in Form eines schematischen Schnittbildes in Vorderansicht dar: die linke Bildhälfte stellt den ausgefederten, die rechte den eingefederten Zustand dar.Figure 2 shows a functional sketch of a front suspension fork in the form of a schematic sectional view in front view: the left half of the image shows the extended state, the right half shows the compressed state.
Das äußere Rohr (3) trägt auf seiner Innenseite in Höhe der Radachse (7) das untere Gleitlager (5), in Höhe der Querverbindung (13) ein weiteres Gleitlager^23). An der Querverbindung (13) greift ein Feder- und/oder Dämpf ungs element (20) an, das im G-abelschaftrohr (19) untergebracht ist. Am oberen Ende des G-abelschaftrohres (19) ist der Verstellungsmechanismus (26) schematisiert dargestellt.The outer tube (3) carries the lower plain bearing (5) on its inside at the height of the wheel axle (7), and another plain bearing at the height of the cross connection (13)^23). A spring and/or damping element (20) which is housed in the fork shaft tube (19) engages the cross connection (13). The adjustment mechanism (26) is shown schematically at the upper end of the fork shaft tube (19).
Fig. 3 zeigt die in Fig. 2 beschriebenen Federgabel in einer auseinandergezogenen perspektivischen Darstellung ihrer Einzelteile.Fig. 3 shows the suspension fork described in Fig. 2 in an exploded perspective view of its individual parts.

Fig. 4 stellt eine auseinandergezogene perspektivische Ansieht einer Federgabel dar, welche als zusätzliches versteifendes Element ein zentrales Rohr (17)) aufweist, welches im Gabelschaftrohr O 9). vermittels eines Gleitlagers (18) verschieblich gelagert ist. Gm eine Einschränkung des Federweges zu vermeiden, weist die Haltevorrichtung (30) des zentralen Rohres eine Formgebung auf, die sich paßgenau in eine entsprechende Aussparung (311 unter der Gabelbrücke (15) einfügt.Fig. 4 shows an exploded perspective view of a suspension fork which has a central tube (17) as an additional stiffening element, which is slidably mounted in the fork shaft tube (9) by means of a sliding bearing (18). In order to avoid a restriction of the spring travel, the holding device (30) of the central tube has a shape that fits precisely into a corresponding recess (311) under the fork bridge (15).
Fig. 5 stellt in einer Funktionsskizze die in Fig. 4 beschriebene durch ein zentrales Rohr zusätzlich versteifte Federgabel dar.Fig. 5 shows a functional sketch of the suspension fork described in Fig. 4, which is additionally stiffened by a central tube.
Fig. 6 zeigt in stark schematisierter Darstellung eine eine einfache Federgabelversion, bei der die Feder- und/ oder Dämpfungselemente (21) zwischen- der Querverbindung (13) der äußeren Rohre (3) und der Gabelbrücke (15) angebracht sind. Ebenso ist die Lage der weitauseinanderliegenden Gleitlager (5/29) skizziert.Fig. 6 shows a highly schematic representation of a simple suspension fork version in which the spring and/or damping elements (21) are mounted between the cross connection (13) of the outer tubes (3) and the fork bridge (15). The position of the widely spaced plain bearings (5/29) is also sketched.

Pig. 10 zeigt eine schematisierte Seitenansicht einer Hinterradfederung als Punktionsskizze. Es ist die Position des unteren G-leitlagers (6) im Bereich der Radachse (8) die Position des oberen Gleitlagers (34) in Höhe der Querverbindung (H) der äußeren Rohre (4) oberhalb des Hinterrades(2). Im Bereich der Querverbindung (16) der inneren Rohre (_12) ist die Pedergabel über eine Achse (35) verschwenkbar am Fahrradrahmen (24) aufgehängt. Die innerem Rohre (12) treten mit ihrem unteren Abschnitt beim Einfedern aus der unteren Öffnung (10) der äußeren Rohre (4) heraus.Pig. 10 shows a schematic side view of a rear wheel suspension as a point sketch. It is the position of the lower plain bearing (6) in the area of the wheel axle (8) and the position of the upper plain bearing (34) at the height of the cross connection (H) of the outer tubes (4) above the rear wheel (2). In the area of the cross connection (16) of the inner tubes (_12), the pedal fork is pivotably suspended on the bicycle frame (24) via an axis (35). The inner tubes (12) emerge with their lower section from the lower opening (10) of the outer tubes (4) when compressed.
Darüberhinaus sind zwei mögliche Positionen eines Peder- und/oder Dämpfungselementes (23/22) gestrichelt dargestellt. In addition, two possible positions of a pedal and/or damping element (23/22) are shown in dashed lines.
