Abstract
Description
Die Erfindung bezieht sich auf eine Vorderrad-Federgabel für ein Zweiradfahrzeug, insbesondere ein Motorrad, mit einem Brückenteil, mit dessen mittlerer Abschnitt das untere Ende einer Lenksäule fest verbunden ist, sowie einem linken und einem rechten Gabelholm, die mit dem Brückenteil verbunden sind, wobei jeder Gabelholm aus mindestens zwei ineinander geführten, zueinander verschiebbaren Rohren und darin angeordneten Feder- und/oder hydraulischen Dämpfungselementen besteht.The The invention relates to a front fork for a two-wheeled vehicle, in particular a motorcycle, with a bridge part, with the middle section, the lower end of a steering column fixed connected, and a left and a right fork leg, the are connected to the bridge part, wherein each fork spar from at least two guided into each other, mutually displaceable Tubes and arranged therein spring and / or hydraulic damping elements consists.

(
Aufgabe der Erfindung ist es, bei einem Motorrad labile und/oder kritische Fahrzustände zu verringern bzw. zu vermeiden, den Fahrkomfort zu verbessern und darüber hinaus bisher nicht erreichbare fahrdynamische Potenziale zu erschließen.task The invention is labile and / or critical in a motorcycle Driving conditions to reduce or avoid the ride comfort to improve and beyond previously unattainable driving dynamics To open up potentials.
Zur Lösung dieser Aufgabe ist vorgesehen, dass mindestens einer der beiden Gabelholme mit kontinuierlich regelbaren Dämpfungselementen versehen ist.to Solution to this problem is provided that at least one the two fork legs with continuously adjustable damping elements is provided.
Vorteilhaft ist hierbei, dass die oben genannten Nachteile durch eine Implementierung regelbarer Dämpfungssysteme und geeigneter Regelstrategie entgegen gewirkt werden.Advantageous Here is that the above-mentioned disadvantages through an implementation adjustable damping systems and suitable control strategy be worked.
Nach einer weiteren günstigen Ausführungsform ist vorgesehen, dass einer der beiden Gabelholme mit kontinuierlich regelbaren Dämpfungselementen versehen ist und der andere Gabelholm ohne Dämpfungselemente ausgebildet ist oder dass einer der beiden Gabelholme mit kontinuierlich regelbaren Dämpfungselementen für die Zugstufe versehen ist und der andere Gabelholm mit konventionellen Dämpfungselementen für die Druckstufe versehen ist oder dass einer der beiden Gabelholme mit kontinuierlich regelbaren Dämpfungselementen für die Druckstufe versehen ist und der andere Gabelholm mit konventionellen Dämpfungselementen für die Zugstufe versehen ist. Vorteilhaft ist hierbei, dass eine ausreichende Dämpfungskraftspreizung mit nur einem regelbaren Dämpfungselement in einem der Gabelholme für alle Zweiradfahrzeuge erzielt werden kann.To a further advantageous embodiment is provided that one of the two fork legs with continuously adjustable damping elements is provided and the other fork leg without damping elements is formed or that one of the two fork legs with continuous adjustable damping elements for rebound is provided and the other fork leg with conventional damping elements for the pressure level is provided or that one of the two Fork legs with continuously adjustable damping elements is provided for the pressure level and the other fork leg with conventional rebound damping elements is provided. The advantage here is that a sufficient Dämpfungskraftspreizung with only one adjustable damping element in one of the fork legs can be achieved for all two-wheeled vehicles.
Nach einem weiteren wesentlichen Merkmal ist vorgesehen, dass einer der beiden Gabelholme mit kontinuierlich regelbaren Dämpfungselementen und der andere Gabelholm mit Elementen zur Niveauregelung versehen sind und dass einer der beiden Gabelholme mit kontinuierlich regelbaren Dämpfungselementen und der andere Gabelholm mit konventionellen Dämpfungselementen einschließlich einer Niveauregelung versehen sind. Hierbei ist von Vorteil, dass zusätzlich noch einer der Gabelholme mit einer Niveauregelung versehen ist, so dass unabhängig des Ladegewichtes der Fahrzeugaufbau immer auf einer gleichen, vorgegebenen Niveaulage einstellbar ist.To Another essential feature is that one of the two fork legs with continuously adjustable damping elements and the other fork leg are provided with elements for level control and that one of the two fork legs with continuously adjustable Damping elements and the other fork leg with conventional Damping elements including a level control are provided. It is advantageous that in addition still one of the fork legs is provided with a level control, so that regardless of the loading weight of the vehicle body always on a same, predetermined level position is adjustable.
In weiterer Ausgestaltung ist vorgesehen, dass als konventionelle Dämpfungselemente mindestens ein mit Dämpfungsventilen versehener Dämpfungskolben vorgesehen ist. Hierbei ist besonders günstig, dass das konventionelle Dämpfungselement manuell einstellbar ist. Vorteilhaft ist, bei einem so genannten passiven Gabelholm, einfache und kostengünstige Dämpfungssysteme einzusetzen, wobei zusätzlich diese Dämpfungssysteme mit manuellen Dampfkraft-Verstell-Einheiten für die Zug- und/oder Druckstufe zu kombinieren sind.In Another embodiment is provided that as a conventional damping elements at least one damping piston provided with damping valves is provided. It is particularly favorable that the conventional damping element is manually adjustable. It is advantageous in a so-called passive fork leg, simple and to use cost-effective damping systems, wherein In addition, these damping systems with manual Steam power adjustment units for the rebound and / or compression stage to combine.
Eine weitere Ausgestaltung sieht vor, dass als regelbares Dämpfungselement mindestens ein extern ansteuerbares, verstellbares Dämpfungsventil vorgesehen ist. Mit Vorteil ist hierbei vorgesehen, dass das Dämpfungsventil von außen elektrisch ansteuerbar ist.A Another embodiment provides that as an adjustable damping element provided at least one externally controllable, adjustable damping valve is. Advantageously, it is provided that the damping valve is electrically controlled from the outside.
Eine Ausgestaltung sieht vor, dass als regelbares Dämpfungselement ein innerhalb des Rohres, in einem Dämpfungskolben angeordnetes Proportionalventil vorgesehen ist. Hierbei lässt sich vorsehen, dass zusätzlich zu dem im Dämp fungskolben angeordneten Proportionalventil zwischen einem Arbeitsraum und einem Ausgleichsraum weitere Ventile angeordnet sind.A Embodiment provides that as an adjustable damping element a within the tube, arranged in a damping piston Proportional valve is provided. Here it can be provided that arranged in addition to the damping piston in Dämp Proportional valve between a working room and a compensation room further valves are arranged.
Nach einer weiteren Alternative ist vorgesehen, dass als regelbares Dämpfungselement ein am Gabelholm, außerhalb des Rohres angeordnetes Proportionalventil vorgesehen ist. Hierbei ist in vorteilhafter Weise vorgesehen, dass zusätzlich zu dem Proportionalventil zwischen einem Arbeitsraum und einem Ausgleichsraum weitere Ventile angeordnet sind.To a further alternative is provided that as a controllable damping element a fork valve located on the outside of the pipe proportional valve is provided. This is provided in an advantageous manner that in addition to the proportional valve between a working space and a compensation chamber further valves are arranged.
Nach einer weiteren Ausgestaltung ist vorgesehen, dass das außerhalb des Rohres angeordnete Proportionalventil im Bereich der Achsaufnahme des Gabelholmes angeordnet ist.According to a further embodiment, it is provided that the arranged outside the pipe proportional valve in the region of the axle of the Gabelholmes is arranged.
