Description
Motorrad mit einer Hinterradaufhängung, deren Federkennlinie verstellbar istMotorcycle with a rear suspension, whose spring characteristic is adjustable
Die vorliegende Erfindung betrifft ein Fahrzeug gemäß dem Oberbegriff des Patentanspruches 1.The present invention relates to a vehicle according to the preamble of
Ein derartiges Fahrzeug ist aus der

Aufgabe der Erfindung ist es, ein Motorrad mit einer Hinterradaufhängung zu schaffen, deren Federkennlinie und Dämpfung mit vergleichsweise geringer Verstellenergie verstellt werden kann.The object of the invention is to provide a motorcycle with a rear suspension, the spring characteristic and damping can be adjusted with comparatively low adjustment energy.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is solved by the features of
Ausgangspunkt der Erfindung ist ein Fahrzeug mit einer Hinterradaufhängung, bei der eine Hinterradschwinge schwenkbar an einem Rahmen oder an einem Motor- bzw. Getriebegehäuse des Fahrzeugs 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.The starting point of the invention is a vehicle with a rear suspension in which a rear swing arm is pivotally mounted on a frame or on an engine or transmission housing of the vehicle. Further, a lever mechanism is provided, via which the rear wheel rocker is resiliently supported with respect to the frame, wherein the lever mechanism comprises a plurality of joints and a strut.
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.Generally speaking, the basic principle of the invention is not to design the spring characteristic and the damping of the shock absorber per se adjustable, but to change the spring characteristic of the rear suspension by adjusting the lever ratios of the lever mechanism.
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 Hinterradaufhängung.This can be achieved by the position of at least one of the joints of the lever mechanism with respect to the frame and / or with respect to the engine housing and / or with respect to a lever of the lever mechanism and / or with respect to the rear swing arm is adjustable. By adjusting the position of at least one joint of the lever mechanism changes to some extent the "gear 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: swing or spring angle of the rear swing arm,
- x: adjustment 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:
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 can be arranged, for example, translationally displaceable. First, it can be connected to a lever of the lever mechanism. On the other hand, it may be displaceable 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 swinging arm of the motorcycle in a guide or slide o.
Alternativ dazu kann das verstellbar angeordnete Gelenk mit einem Exzenterelement verbunden sein, wobei eine Verstellung der Position des Gelenks durch Drehverstellung des Exzenterelements erfolgt.Alternatively, the adjustably arranged joint may be connected to an eccentric element, wherein an adjustment of the position of the joint takes place 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 joint is manually adjustable, z. B. by means of a handwheel or a screw mechanism. Alternatively, an actuator adjustment may 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 set or lockable in its current position. A self-locking is z. B. given a screw mechanism. If no self-locking is given, then at least a lockability is ensured, so that an automatic displacement of the adjustable joint is excluded while driving.
