Abstract

The transmission has at least one pedal (4) and turning point (S) in drive connection with it. Force transmission (F) takes place through a lever (3), which is in drive connection with and at an angle to a rack (2). The rack is in drive connection with the bicycle wheel hub. The drive connection may pass over a gear wheel and a rack.

Description

Die Erfindung betrifft eine Getriebe, insbesondere ein Fahrradantrieb mit wenigstens einer Pedale, einem Gestränge und einem damit in Antriebsverbindung stehenden Abtrieb, der vor allem primär durch Muskelbewegung eines Menschen in Rotation versetzt wird. The invention relates to a transmission, in particular a bicycle drive with at least a pedal, a linkage and a drive connection with it Downforce, which is primarily caused by a person's muscle movement in rotation is transferred.

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 9 dargestellt. In Fig. 1 shows an inventive, primarily driven by muscle movement of a human bicycle 9 is shown.

Mit 1 ist der Abtrieb bezeichnet, d. h. auch: die Antriebsnabe des Fahrrades. Im Ausführungsbeispiel handelt es sich um ein einfaches Zahnrad mit einer hier nicht näher beschriebenen Anzahl von Zähnen. Eine Gestränge - hier in der Ausführung als Zahnstange - 2 steht einerseits mit 1 in Antriebsverbindung und andererseits mit dem seinerseits drehbeweglich in Z gelagerten Hebel 3 und somit mechanisch gekoppelt in Verbindung. Mit 4 ist die Pedale gekennzeichnet. 2 und 3 sind in einem insbesonderen spitzen Winkel relativ zueinander angeordnet. Letzteres dient zur besseren Kraftübertragung bzw. Drehmomentenoptimierung. Eine auf die Pedale 4 wirkende (Muskel-)Kraft F wird bei der Abwärtsbewegung vorteilhafterweise gleichzeitig auf ein elastisches Element, insbesondere (hier: Zug-)Feder 7 übertragen, welche in der nachfolgenden Aufwärtsbewegung der Pedale gespeicherte Energie in die ansonsten im segmentarischen Bereich im Leerlauf - durch Freilaufkupplung(en) - drehenden Zahnkranz 1 liefert; dieser ist drehbeweglich im Punkt S gelagert. The output is denoted by 1 , ie also: the drive hub of the bicycle. In the exemplary embodiment, it is a simple gearwheel with a number of teeth which is not described in more detail here. A linkage - here in the form of a toothed rack - 2 is connected on the one hand to 1 in a drive connection and on the other hand to the lever 3, which is in turn rotatably mounted in Z, and thus mechanically coupled. The pedals are marked with 4 . 2 and 3 are arranged at a particularly acute angle relative to one another. The latter is used for better power transmission or torque optimization. A (muscle) force F acting on the pedals 4 is advantageously simultaneously transferred to an elastic element, in particular (here: tension) spring 7 during the downward movement, which energy stored in the subsequent upward movement of the pedals into the otherwise in the segmental area in Idling - through freewheel clutch (s) - rotating ring gear 1 supplies; this is rotatably mounted 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.

Mit 5 und 6 sind Anschlagpuffer markiert, welche eine elastische und dennoch ortsfeste Begrenzung der Hubbewegung erzeugen. Sie sind mit dem Rahmen des Fahrrades fest verbunden. With 5 and 6 stop buffers are marked, which generate an elastic, yet fixed limitation of the stroke movement. They are firmly attached to the frame of the bike.

Ein drehbewegliches, aber ansonsten ortsfestes, also insbesondere am Fahrradrahmen fest verbundenes Führungselement 8 hält die Zahnstange 2 in Antriebsverbindung mit dem Zahnrad 1. In vorteilhafter Weise sind zwei (nicht gezeigte) Freillaufkupplungen mit 1 verbunden. A rotatable but otherwise stationary guide element 8 , that is to say in particular firmly connected to the bicycle frame, holds the rack 2 in drive connection with the gear wheel 1 . Advantageously, two one-way clutches (not shown) are connected to 1.

Der Drehmomentenverlauf eines konventionellen Kettenantriebes unterscheidet sich drastisch vom erfindungsgemässen Drehmomentenverlauf: Bei der Erfindung kann beispielsweise das Spitzendrehmoment mehr als verdoppelt werden, was weniger Energieverbrauch bei vergleichbarer Fahrgeschwindigkeit bedeutet. The torque curve of a conventional chain drive differs drastic of the torque curve according to the invention: With the invention can For example, the peak torque can be more than doubled, which is less Energy consumption at a comparable driving speed means.

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.
