Description
Die vorliegende Erfindung betrifft ein Motorrad gemäß dem Oberbegriff des Patentanspruches 1.The The present invention relates to a motorcycle according to the Preamble of claim 1.

Aufgabe der Erfindung ist es, ein Motorrad mit einer Hinterradaufhängung zu schaffen, deren Federkennlinie und Dämpfung mit vergleichsweise geringer Verstellenergie verstellt werden kann.task The invention is a motorcycle with a rear suspension to create their spring characteristic and damping with comparatively low Adjustment energy can be adjusted.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. Advantageous embodiments and further developments of the invention are to refer to the dependent claims.
Ausgangspunkt der Erfindung ist ein Motorrad mit einer Hinterradaufhängung, bei der eine Hinterradschwinge schwenkbar an einem Rahmen oder an einem Motor- bzw. Getriebegehäuse des Motorrads angeordnet ist. Ferner ist ein Hebelmechanismus vorgesehen, über den die Hinterradschwinge federnd in Bezug auf den Rahmen abgestützt ist, wobei der Hebelmechanismus mehrere Gelenke und ein Federbein aufweist.starting point the invention is a motorcycle with a rear suspension, in which a rear swing arm hinged to a frame or on a motor or gear housing of the motorcycle arranged is. Furthermore, a lever mechanism is provided over the the rear swing arm supported resiliently with respect to the frame is, with the lever mechanism multiple joints and a strut having.
Ganz allgemein besprochen besteht das Grundprinzip der Erfindung darin, nicht die Federkennlinie und die Dämpfung des Federbeins an sich verstellbar zu konzipieren, sondern durch eine Verstellung der Hebelverhältnisse des Hebelmechanismus die Federkennlinie der Hinterradaufhängung zu verändern.All Generally speaking, the basic principle of the invention is not the spring characteristic and the damping of the strut adjustable in itself, but by an adjustment the lever ratios of the lever mechanism the spring characteristic to change the rear suspension.
Dies kann dadurch erreicht werden, dass die Position mindestens eines der Gelenke des Hebelmechanismus in Bezug auf den Rahmen und/oder in Bezug auf das Motor- bzw. Getriebegehäuse und/oder in Bezug auf einen Hebel des Hebelmechanismus und/oder in Bezug auf die Hinterradschwinge verstellbar ist. Durch Verstellen der Position mindestens eines Gelenks des Hebelmechanismus ändert sich in gewissem Umfang das „Übersetzungsverhältnis” des Hebelmechanismus und damit die Federkennlinie der Hinterrad aufhängung.This can be achieved by the position of at least one the joints of the lever mechanism with respect to the frame and / or with respect to the engine or transmission housing and / or in Reference to a lever of the lever mechanism and / or in relation to the rear swing arm is adjustable. By adjusting the position at least one joint of the lever mechanism changes to some extent the "ratio" of the Lever mechanism and thus the spring characteristic of the rear suspension.
Geht
man von einem Federbein aus, das über seinen Federweg s
eine konstante Federrate c aufweist, so gilt für die vom
Federbein übertragene Kraft
- ϕ:
- Schwenk- bzw. Federwinkel der Hinterradschwinge,
- x:
- Verstellkoordinate des verstellbaren Gelenks des Hebelmechanismus.
- φ:
- Swivel or spring angle of the rear swing arm,
- x:
- Adjusting coordinate of the adjustable joint of the lever mechanism.
Für
ein Federbein mit konstanter Federrate gilt somit ganz allgemein
Für
ein Federbein, dessen Federrate sich über dem Federweg
s des Federbeins ändert gilt ganz allgemein:
Nach einer Weiterbildung der Erfindung ist das verstellbar angeordnete Gelenk mit einem Hebel verbunden, der im Wesentlichen auf Zug bzw. Druck aber nicht oder zumindest nur wenig auf Biegung beansprucht ist. Ferner ist die Richtung, in der die Position des Gelenks verstellbar ist, im Wesentlichen senkrecht zu dem primär auf Zug bzw. Druck beanspruchten Hebel. Zumindest schließt die Richtung, in der die Position des Gelenks verstellbar ist, einen Winkel zwischen 45° und 90° mit dem auf Zug bzw. auf Druck beanspruchten Hebel ein. Dadurch wird erreicht, dass die für die Verstellung des verstellbaren Gelenks erforderliche Kraft, sofern man Reibung vernachlässigt, sehr gering bzw. Null ist.To a development of the invention is the adjustably arranged Joint connected to a lever, which is essentially on train or Pressure but not or at least only slightly stressed on bending is. Further, the direction in which the position of the joint is adjustable is substantially perpendicular to the primary train or Pressure stressed lever. At least that's the direction in which the position of the joint is adjustable, an angle between 45 ° and 90 ° with the stressed on train or on pressure Lever. This will accomplish that for the adjustment the adjustable joint required force, provided that friction neglected, very low or zero.
Das verstellbare Gelenk kann beispielsweise translatorisch verschiebbar angeordnet sein. Zum einen kann es mit einem Hebel des Hebelmechanismus verbunden sein. Zum anderen kann es in einer Führung bzw. Kulisse o. ä. in bzw. an oder relativ zu dem Rahmen und/oder dem Motor- bzw. Getriebegehäuse und/oder einem anderen Hebel des Hebelmechanismus und/oder der Hinterradschwinge des Motorrads verschiebbar sein.The adjustable joint, for example, translationally displaceable be arranged. For one it can be done with a lever of the lever mechanism be connected. On the other hand, it can be in a leadership or Backdrop o. Ä. In or on or relative to the frame and / or the engine or transmission housing and / or another Lever of the lever mechanism and / or the rear swingarm of the motorcycle be displaceable.
Alternativ dazu kann das verstellbar angeordnete Gelenk mit einem Exzenterelement verbunden sein, wobei eine Verstellung der Position des Gelenks durch Drehverstellung des Exzenterelements erfolgt.alternative To do this, the adjustably arranged joint with an eccentric element be connected, with an adjustment of the position of the joint performed by rotational adjustment of the eccentric element.
Es kann vorgesehen sein, dass die Position des verstellbar angeordneten Gelenks manuell verstellbar ist, z. B. mittels eines Handrads oder eines Schraubmechanismus. Alternativ dazu kann auch eine aktuatorische Verstellung vorgesehen sein, z. B. mittels eines elektromechanischen oder eines hydraulischen Aktors.It can be provided that the position of the adjustable arranged Joint is manually adjustable, z. B. by means of a handwheel or a screw mechanism. Alternatively, an actuatory Adjustment be provided, for. B. by means of an electromechanical or a hydraulic actuator.
Vorzugsweise ist das verstellbare Gelenk in seiner momentanen Position selbsthemmend festgelegt oder arretierbar. Eine Selbsthemmung ist z. B. bei einem Schraubmechanismus gegeben. Sollte keine Selbsthemmung gegeben sein, so ist zumindest eine Arretierbarkeit sicherzustellen, so dass eine selbsttätige Verschiebung des verstellbaren Gelenks während der Fahrt ausgeschlossen wird.Preferably the adjustable joint is self-locking in its current position fixed or lockable. A self-locking is z. B. at a Given screw mechanism. Should not be self-locking, so at least a lockability is ensured, so that a automatic displacement of the adjustable joint during the ride is excluded.
