Abstract
Description
Die Erfindung betrifft eine Hubgetriebe, insbesondere ein Fahrradantrieb mit wenigstens einer Pedale, einem Gestänge und einer damit in Antriebsverbindung stehenden Kurbel, die vor allem primär durch Muskelbewegung eines Menschen in Rotation versetzt wird. The invention relates to a lifting gear, in particular a bicycle drive at least one pedal, a linkage and a drive connection with it standing crank, which is primarily caused by a person 's muscle movement Rotation is set.
Muskelbetriebene Fahrräder sind allgemein bekannt und werden in der Regel durch Kettenantriebe betrieben. Hierbei wird die Kraft auf mindestens eine Pedale übertragen welche über eine Kette das Hinterrad antreibt. Muscle powered bicycles are well known and are usually used by Chain drives operated. This applies the force to at least one pedal transmitted which drives the rear wheel via a chain.
Diese Art und Weise der Kraftübertragung ist keineswegs als optimal zu bezeichnen. Sinn und Zweck der Erfindung ist also eine deutliche Verbesserung der Wirkungsgradkette von Muskelbewegung eines Menschen zur Kraftübertragung auf die Fahrbahn zu erzielen. This way of power transmission is by no means to be described as optimal. The sense and purpose of the invention is a significant improvement in Efficiency chain from a person's muscle movement to power transmission to achieve the lane.
Die Lösung dieser Aufgabenstellung wird nachfolgend und in den Patentansprüchen beschrieben; außerdem findet die Erklärung anhand von Fig. 1 statt. The solution to this problem is described below and in the claims; in addition, the explanation takes place with reference to FIG. 1.
In Fig. 1 ist ein erfindungsgemäßes, primär durch Muskelbewegung eines Menschen angetriebenes Fahrrad 6 dargestellt. In Fig. 1 shows an inventive, primarily driven by muscle movement of a human bike 6 is illustrated.
Mit 1 ist die Kurbel bzw. Der Exzenter bezeichnet, d. h. die Antriebsnabe des Fahrrades. Eine Gestänge 2 steht einerseits mit 1 drehbeweglich in Antriebsverbindung und andererseits mit dem seinerseits drehbeweglich in Z gelagerten Hebel 3 mechanisch gekoppelt in Verbindung. Mit 4 ist lediglich ein in Relation zu 3 starres Koppelelement markiert. Letzteres dient zur besseren Kraftübertragung bzw. Drehmomentenoptimierung. Eine auf die Pedale 5 wirkende (Muskel-) Kraft wird bei der Abwärtsbewegung vorteilhafterweise gleichzeitig auf ein elastisches Element, insbesondere (hier: Zug-) Feder E übertragen, welche in der nachfolgenden Aufwärtsbewegung der Pedale gespeicherte Energie in die ansonsten im segmentarischen Bereich im Leerlauf drehende Kurbel 1 liefert. Die Kurbel ist drehbeweglich im Punkt S gelagert. With 1 the crank or the eccentric is designated, ie the drive hub of the bicycle. A linkage 2 is connected on the one hand with 1 rotatably in drive connection and on the other hand mechanically coupled to the lever 3, which in turn is rotatably mounted in Z. 4 is only a coupling element which is rigid in relation to 3. The latter is used for better power transmission or torque optimization. A (muscle) force acting on the pedals 5 is advantageously simultaneously transferred to an elastic element, in particular (here: tension) spring E during the downward movement, which energy stored in the subsequent upward movement of the pedals into the otherwise idle in the segmental range rotating crank 1 delivers. The crank is pivoted at point S.
Mit OT und UT sind jeweils der (oder die, bei mehrfacher, insbesonderer links- und rechtsseitigen Anordnung) obere und untere Totpunkt bzw. Umkehrpunkt bezeichnet. Bedingt durch den insbesondere spitzen Winkel zwischen 2 und 3 wird eine durch die angewinkelte Stellung eines Beines des Menschen erzeugte, ohnehin gute Krafterzeugung nochmals wesentlich verstärkt. With OT and UT are the (or those, in the case of multiple, in particular left and right-hand arrangement) denotes upper and lower dead center or reversal point. Due to the particularly acute angle between 2 and 3, one is the angled position of a human leg created anyway good Power generation significantly increased again.
Auch in erfindungsgemäßem Antriebskonzept lässt sich eine konventionelle Mehrgang-Nabenschaltung integrieren. A conventional one can also be used in the drive concept according to the invention Integrate multi-speed hub gear.
Im Ergebnis ist erfindungsgemäßes Aggregat einfach im Aufbau, kostengünstig in der Fertigung und effektiv in seiner Wirkung. Es lässt sich überall dort sehr gut betreiben, wo muskelbewegte Transportmittel zum Einsatz gelangen sollen. As a result, the unit according to the invention is simple in construction, inexpensive in the manufacture and effective in its effect. It can be done very well anywhere operate where muscle-moving means of transport are to be used.
