Abstract

In order to facilitate and better utilise the power transmission in the case of cycles and machines, the driving or transmission pulley is divided into a plurality of semicircular parts. These are secured rotatably in an eccentric manner on a baseplate, thereby making it impossible to fit the parts of the pulley together incorrectly. A ring on which two pins for each part of the pulley are fixed brings about the opening (enlargement or reduction of the diameter) and closure of the pulley. This makes possible an increase or reduction in the rotational speed on a plane with drive and transmission. The parts of the pulley are held fast in the desired position by a single-plate dry clutch, a centrifugal clutch or a Bowden pull. Since the number of parts of the pulley and the diameter can be selected in accordance with requirements, the uses to which the invention can be put are many and various.

Description

Beschreibung:Description:

Die Scheibe wird in sieben Teile und in regelmäßigem Abstand, außerhalb der Achsmitte (exzentrisch), auf einer runden, 2mm starken, Grundplatte, dreh befestigt. Durch die halbkreisähnliche Form der Teile, der drehbaren und exzentrischen Anbringung, wird bei der Entfaltung der Durchmesser größer.The disc is in seven parts and regularly spaced, outside the center of the axis (eccentric), rotatably mounted on a round, 2mm thick base plate. Due to the semicircular shape of the parts, the rotatable and eccentric mounting, the diameter increases as it unfolds.

Je nach Bedarf kann durch die wahlweise geänderte Form undÄnordnung der Durchmesser vergröFert werden. Depending on your needs, the optionally changed shape and arrangement the diameter can be increased.

Nicht auf der Zeichnung dargestellt: Das Öffnen und Schließen (verändern des Durchmesse wird durch einen Ring bewirkt, auf dem, je Scheibenteil, zwei Bolzen,in bestimmten Abstand befestigt sind. Not shown on the drawing: Opening and closing (change of the diameter is caused by a ring on which, for each disc part, two bolts in fixed at a certain distance.

Beim Drehen dieses Ringes, im Uhrzeigersinn, öffnet -q die Scheibe, da die angebrachten Bolzen die Teile na außen drücken. When turning this ring clockwise, -q opens the disk, because the attached bolts press the parts to the outside.

Beim Zurückdrehen des Ringes schließt sich die Scheibe wieder zur Normalgröße. When the ring is turned back, the disk closes again Normal size.

Daß Ganze wird durch eine Einscheiben-Trockenkupplung oder Fliehkraftkupplung oder Bowdenzung funktionsfä gemacht und gleichzeitig stabilisiert. The whole thing is achieved by a single-disc dry clutch or centrifugal clutch or Bowdenzung made functional and stabilized at the same time.

Es ist bekannt, daß Keilriemenscheiben, horizontalverstellbar, bei Maschinen eingesetzt werden und auch einwandfrei arbeiten.It is known that V-belt pulleys, horizontally adjustable, at Machines are used and also work properly.

Weiterhin ist bekannt, daß Fahrräder mit einer Nabenschaltung (Planet ens chaltung) oder Z ehugang-Kett ens chaltung ausgestattet sind.It is also known that bicycles with a gear hub (Planet circuit) or access chain circuit are equipped.

Jedoch können diese Schaltungen, wenn Antrieb und Übersetzung verstellbar sein sollen, nur auf mehreren Rbenen funktionieren.However, these circuits can be adjusted if the drive and translation are adjustable should only work on several levels.

Die Aufgabe dieser Erfindung ist es, eine Erleichterung und bessere Ausnutzung der Kraftübertragung bei Fahrrädern und einen größeren Wirkungskreis und Wirkungsgrad bei Maschinen zu erreichen.The object of this invention is to provide relief and better Utilization of the power transmission in bicycles and a larger sphere of activity and to achieve efficiency in machines.

Diese Aufgabe wird bei einer gattungsgemänen Einordnung durch die kennzeichnenden Merkmale ies Anspruchs 1 gelöst.With a generic classification, this task is carried out by the Characteristic features of this claim 1 solved.

Um eine individuellgemäße Gestaltung und Wirkung zuerreichen, kann man den Durchmesser (Grundform) der Antriebs- bzw.In order to achieve an individual design and effect, the diameter (basic shape) of the drive or

Übersetzungsscheibe frei wählen.Freely choose the translation disc.

Dabei ist aiich einer freien Wahl der Anzahl und der Form der Teile eine Einschränkung nur im technischen Bereich und der Raumaufteilung gesetzt.There is a free choice of the number and shape of the parts a restriction only set in the technical area and the room layout.

Der Vorteil dieser Erfindung liegt darin, dae die Schaltung und somit eine Drehzahlsteigerung bzw. -minderung auf einer Ebene stattfindet und einen höheren Wirkungsgrad gewährleistet.The advantage of this invention is that the circuit and thus a speed increase or decrease takes place on one level and a higher one Efficiency guaranteed.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird funktionsmäüßig in folgenden Positionen aufgeführt: 1. Antriebswelle oder Tretlager 2. bewegliche Teile der Antriebs- bzw. Übersetzungsscheibe 3. Keilriemen oder Kette 4. Echeibenteil in I'Iormalgröße - Leerseite -An embodiment is shown in the drawing and will Functionally listed in the following positions: 1. Drive shaft or bottom bracket 2. Moving parts of the drive or transmission pulley 3. V-belt or chain 4. Full size oak part - blank page -
