Abstract
Description
Fahrradschalteinheit mit elektrohydraulischer Ansteuerung dadurch gekennzeichnet, daß die Energie für die Ausführung des Schaltvorgangs über einen Geberzylinder hydraulisch auf einen elektrisch auf Zug oder Druck umschaltbaren Nehmerzylinder über tragen wird, wobei auch die Ansteuerung von ein und dem selben Geberzylinder auf verschiedene Nehmerzylinder über elektrohydrau lische Weichen erfolgt.Bicycle switching unit with electro-hydraulic control characterized in that the energy for the execution of the Switching operation hydraulically on a master cylinder slave cylinder electrically switchable to train or pressure will carry, with the control of one and the same Master cylinder on different slave cylinders via electrohydrau switch is made.
Die beschriebene Schalteinheit ist dadurch ausgezeichnet, daß ihr Rastermechanismus direkt am Schaltwerk angebracht ist und die Po sitionierung nicht durch das Reibmoment einer Schaltgriffklemmung erfolgt. Ebenso wird die Schaltkraft aktiv in beide Schaltrich tungen ausgeführt. Dadurch muß nicht die Kraft einer Gegenzugfe der überwunden werden. Die Energie sämtlicher Betätigungen des vorderen und hinteren Schaltwerks wird durch den selben Geberzy linder bereitgestellt, die Energieführung von elektrischen Venti len koordiniert. Der vordere Umwerfer vermag die Kette aktiv auf das größere Ritzel zu heben.The switching unit described is characterized in that you Grid mechanism is attached directly to the rear derailleur and the bottom not due to the frictional torque of a gear lever clamp he follows. The shifting force is also active in both shift gauges operations carried out. This does not have to be the force of a counter pull to be overcome. The energy of all operations of the front and rear derailleur is by the same Geberzy Linder provided the energy supply of electrical valves len coordinates. The front derailleur can actively open the chain to lift the larger sprocket.
Wie bekannt, werden heute Fahrradschaltungen über Züge in eine Richtung aktiv gegen eine Feder betätigt, die die gegenläufige Bewegung bewerkstelligt. Die Positionierung erfolgt über die Schalthebel.As is known, bicycle circuits are now used in trains Actively actuated against a spring which is the opposite Movement accomplished. The positioning takes place via the Gear lever.
Durch den notwendigen Gegenzug der Schaltwerkfedern ist ein gro ßes Reibmoment der Zugbetätigung unumgänglich. Für jede Aktivie rung ist mindestens eine Seilführung notwendig. Der vordere Um werfer benötigt viel Platz über den Ritzeln und verzögert den Schaltvorgang, indem er die Kette an einem relativ tiefen Um fangswinkel gegen das größere Ritzel drückt.Due to the necessary return of the rear derailleur springs is a big ß frictional moment of the train actuation inevitable. For every asset at least one rope guide is necessary. The front order thrower takes up a lot of space above the pinions and slows it down Shifting process by placing the chain at a relatively low order angle against the larger pinion.
Der Erfindung liegt die Aufgabe zu Grunde, den Schaltvorgang leicht und schnell zu gestalten und die Bedienung auf nur zwei Bedienungselemente zu beschränken, die durch ihre Kombination noch die Möglichkeit zur Bedienung weiterer Funkionen in Reserve halten (z. B. Licht, Warnsignal, Computer u. ä.).The invention is based on the task of switching easy and fast to design and operation on just two Limit controls by their combination the possibility of operating additional functions in reserve hold (e.g. light, warning signal, computer, etc.).
Leichte exakte Handhabung, Wartungsarmut, Betriebssicherheit, lo gische, leicht erreichbare Bedienung.Easy exact handling, low maintenance, operational safety, lo smooth, easily accessible operation.
