Abstract
Description
Die Erfindung betrifft sowohl ein Verfahren zur Lenkung eines Fahrrads o. dgl. bzw. Motorrads, Motorfahrrads usw., bestehend darin, dass in einer Kurve der Fahrer mittels eines Lenkers/Lenkhandhebels eine geradlinige oder gebogene Gabel, deren Gabelschaft an einer am Fahrradrahmen untergebrachten Gabelnabe angeordnet ist, mit einem lenkbaren Vorderlaufrad seines besagten Verkehrsmittels in die Kurvenrichtung dieses Verkehrsmittels unter einem von der Lage des Geradeausfahrens abgemessen Einschlagwinkel ansetzt und dabei die mit der Geschwindigkeit und dem Kurvenradius korrespondierende Neigung des Fahrradrahmens einstellt, als auch ein Fahrrad o. dgl., vorherbestimmt zur Implementierung des erwähnten Verfahrens zur Lenkung, welches die an einem vorderen Ende des Fahrradrahmens schwenkbar angebrachte, mit dem lenkbaren Vorderlaufrad und dem Lenker/Lenkhandhebel ausgerüstete Gabel, deren Gabelschaft an der am Fahrradrahmen untergebrachten Gabelnabe angeordnet ist, und zumindest ein an einem hinteren Ende des Fahrradrahmens angeordnetes Hinterlaufrad aufweist.The invention relates to both a method for steering a bicycle o. The like. Motorcycle or motorcycles, etc., consisting in that in a curve of the driver by means of a handlebar / steering lever, a straight or curved fork, the steerer tube on a fork frame housed on the bicycle frame is arranged, with a steerable front wheel of its said means of transport in the direction of this traffic means measured at a measured from the position of straight driving angle and thereby adjusts the corresponding with the speed and the curve radius inclination of the bicycle frame, as well as a bicycle o. The like., Predetermined to implement the mentioned method of steering, which is arranged at a front end of the bicycle frame pivotally mounted, equipped with the steerable front wheel and the handlebar / steering lever fork, the steerer is arranged on the bicycle frame accommodated fork hub, and at least one Having a rear end of the bicycle frame arranged rear wheel.
In bekannten technischen Lösungen zur Lenkung eines Fahrrads o. dgl. wendet sein Fahrer die Gabel, deren Gabelnabe immer in der Fahrradrahmenebene liegt, mit einem lenkbaren Vorderlaufrad praktisch ohne Verschiebung des Berührungspunkts des lenkbaren Vorderlaufrads mit dem Boden von der Fahrradrahmenebene seines Fahrradrahmens, denn die Gabelbiegung der Gabel maximal 8,5 cm ausmacht. In der Kurve neigt sich das Zweirad, dargestellt beispielsweise in
Bei Kurvenneigung kann das Pedal des Antriebs sowohl dieser Dreiräder als auch der herkömmlichen Zweiräder den Boden berühren. Dazu ist ihr Aufbau sowohl kompliziert und schwer als auch zieht die Kraft des Fahrers und Raum daneben ab.When cornering, the pedal of the drive of both these tricycles and the conventional two-wheelers can touch the ground. In addition, their structure is both complicated and heavy, as well as subtracting the power of the driver and space next to it.
Die Aufgabe der vorliegenden Erfindung besteht darin, den Schutz des Fahrradfahrens vor Unfällen bei einem einfachen Aufbau des Fahrrads erhöhen.The object of the present invention is to increase the protection of cycling from accidents in a simple construction of the bicycle.
Diese Aufgabe wird mit Merkmalen des 1. Patentanspruchs gelost. Weitere Vervollkommnungen ergeben sich aus den Unteransprüchen.This object is achieved with features of the first claim. Further improvements emerge from the subclaims.
Erfindungsgemäß verschiebt in der Kurve der Fahrer gleichzeitig mit der unter dem Einschlagwinkel bestimmten Wendung des lenkbaren Vorderlaufrads in die Kurvenrichtung das lenkbare Vorderlaufrad entgegen die Kurvenrichtung von der Lage des Geradeausfahrens und hält dadurch der Fahrradrahmen annähernd vertikal. In der Kurve kann der Fahrer gleichzeitig mit der unter dem Einschlagwinkel bestimmten Wendung des lenkbaren Vorderlaufrads in die Kurvenrichtung das lenkbare Vorderlaufrad um eine annähernd waagerechte Achse in die Kurvenrichtung von der Lage des Geradeausfahrens drehen. In der Kurve kann der Fahrer gleichzeitig mit der unter dem Einschlagwinkel bestimmten Wendung des lenkbaren Vorderlaufrads in die Kurvenrichtung die Gabelnabe zusammen mit dem lenkbaren Vorderlaufrad um eine annähernd waagerechte Achse in die Kurvenrichtung von der Lage des Geradeausfahrens drehen. Erfindungsgemäß ist die an dem vorderen Ende des Fahrradrahmens befindliche Gabelnabe in Bezug auf den Fahrradrahmen um eine annähernd waagerechte Achse schwenkbar angebracht. Die Gabelnabe kann an der an dem Fahrradrahmen schwenkbar angebrachten Längsachse befestigt sein, dabei kann die Längsachse an einer an dem Fahrradrahmen starr befestigten Achsnabe schwenkbar angebracht sein. Die Längsachse kann mittels einer Handkurbel gesteuert sein. Die Achsnabe des Fahrradrahmens kann mit einem die Wendung der Gabelnabe bestimmten Antrieb z. B. Handzahngetriebe ausgerüstet ist. Der Gabelschaft kann mit dem Fahrradrahmen des Fahrrads mittels einem Getriebe beispielsweise einem Kegelzahngetriebe, dessen angetriebenes Kegelzahnrad bzw. Kegelzahnradsektor der Achsnabe koaxial untergebracht und an dem Fahrradrahmen befestigt ist, verbunden sein. Die Gabelnabe und/oder die Längsachse kann mit dem Fahrradrahmen mittels eines die Gabelnabe in die Fahrradrahmenebene zurückstellenden Federelements z. B. einer Spiralfeder/Drehstabsfeder verbunden sein. Die größtmögliche Drehwinkel der Wendung der Gabelnabe oder/und der Längsachse um die Achse der Achsnabe kann mittels der Anschläge begrenzt sein.According to the invention moves in the corner of the driver simultaneously with the determined by the turning angle turn the steerable front wheel in the direction of the steerable front wheel counter to the direction of the curve of the position of straight driving and thereby holds the bicycle frame approximately vertically. In the turn, the driver can simultaneously turn the steerable front wheel about the horizontal turning axis in the turning direction from the straight traveling position with the turning of the steerable front wheel in the turning direction. In the turn, the driver can turn the fork hub together with the steerable front wheel about an approximately horizontal axis in the turning direction from the straight traveling position simultaneously with the turning angle determined turning of the steerable front wheel in the turning direction. According to the present invention, the fork hub located at the front end of the bicycle frame is pivotally mounted about an approximately horizontal axis with respect to the bicycle frame. The fork hub may be secured to the longitudinal axis pivotally mounted on the bicycle frame, while the longitudinal axis may be pivotally mounted on an axle hub fixed rigidly to the bicycle frame. The longitudinal axis can be controlled by means of a hand crank. The axle hub of the bicycle frame can with a turn the Gabelnabe certain drive z. B. manual gear is equipped. The steerer may be connected to the bicycle frame of the bicycle by means of a gear, for example, a bevel gear, whose driven bevel gear or bevel gear sector of the axle hub coaxially housed and fixed to the bicycle frame, be connected. The fork hub and / or the longitudinal axis can with the bicycle frame by means of a fork hub in the bicycle frame plane restoring spring element z. B. a coil spring / torsion bar spring connected. The maximum possible angle of rotation of the turn of the fork hub and / or the longitudinal axis about the axis of the axle hub can be limited by means of the stops.
Die Erfindung soll nachstehend an Ausführungsbeispielen näher erläutert werden. Es zeigen:The invention will be explained in more detail below by exemplary embodiments. Show it:
