Description

· &PSgr; · &PSgr;

Die Erfindung betrifft ein stufenloses Zugmittelgetriebe mit verstellbaren Riemenscheiben oder Kettenräder.The invention relates to a continuously variable transmission with adjustable pulleys or sprockets.

Stand der Technik : State of the art :

Es ist bekannt ,daß die meisten Zugmittelgetrieben mit zwei nicht verstellbaren Riemenscheiben oder Kettenräder und mit einem festen Übersetzungsverhältnis arbeiten.It is known that most traction drives work with two non-adjustable pulleys or sprockets and with a fixed gear ratio.

Wenn man die Übersetzung verändern möchte,dann muß das Zugmittelglied (Riemen oder Kette) von einem Rad zum Anderen wechseln, wie z.b. bei den Mountain Bikes gibt es am Hinterrad 8 Kettenräder und bei den Pedalkurbeln weitere 3 Kettenräder. Hier muß das Zugmittelglied (die Kette) von einem Rad zum anderen springen und sehr oft mit Rutschen und Krach ,um die gewünschte Übersetzung zu erreichen.If you want to change the gear ratio, the traction link (belt or chain) has to switch from one wheel to another, for example on mountain bikes there are 8 sprockets on the rear wheel and another 3 sprockets on the pedal cranks. Here the traction link (the chain) has to jump from one wheel to the other and very often with slipping and noise in order to achieve the desired gear ratio.

In der Frühzeit des Motorrades,wurde eine verstellbare Riemenscheibe und dazu ein Gestänge (sog. Rüge Multi), welche das ein Scheibenpaar zusammenschob,während sich das andere auseinander bewegte. Später wurde das seitlich verstellbare Riemenscheiben-Getriebe (bek. als DAF-Variomatic) entwickelt.In the early days of the motorcycle, an adjustable pulley and a rod (so-called Rüge Multi) were used, which pushed one pair of pulleys together while the other moved apart. Later, the laterally adjustable pulley transmission (known as DAF Variomatic) was developed.

Aber wegen der hohen Schlupf und der Raschenverschleiß, sowie die komplizierte Mechanik und Steuerung könnten sie sich auf den Markt nicht durchsetzen, weil auch der Umschlingungswinkel der vorderen Scheibe zu klein war.But because of the high slip and rapid wear, as well as the complicated mechanics and control, they could not prevail on the market because the wrap angle of the front disc was too small.

♦:*♦ ; .:..:,« „· s?ite 2-♦:*♦; .:..:,« „· page 2-

Ferner sind die o.g. Getriebearten sehr reparaturanfällig und zumindest brauchen sie ständig Einstellungen.Furthermore, the above-mentioned types of transmission are very prone to repairs and at least they need constant adjustments.

Der Erfindung lag daher die Aufgabe zugrunde, ein konstruktiv einfaches Zugmittelgetriebe mit verstellbaren Riemenscheiben oder Kettenräder zu entwickeln, das die Nachteile und Umstände der bisherigen Getriebe dieser Art zu beseitigen.The invention was therefore based on the object of developing a structurally simple traction mechanism transmission with adjustable pulleys or sprockets that would eliminate the disadvantages and circumstances of previous transmissions of this type.

Die Erfindung hat es zu Aufgabe gemacht,ein neues Zugmittelgetriebe zu entwickeln,das die folgende Vorteile haben kann :The invention aims to develop a new traction mechanism that can have the following advantages:

1. Sehr einfache Konstruktion und Funktion. 2.Wartungsfreundlich,weil das Zugmittelglied nicht mehr zwischen die Kettenräder springen muß.1. Very simple design and function. 2. Easy to maintain because the traction link no longer has to jump between the sprockets.

3. Bedienungsfreundlich,weil die Verstellung eifacher ist, oder automatisch durch die Verwendung von Fliehkraftregler. 3. User-friendly, because the adjustment is simpler, or automatic through the use of centrifugal governor.

4. Kein Schlupf oder rascher Verschleiß,weil der Umschlingungswinkel großer ist.4. No slippage or rapid wear because the wrap angle is larger.

5. Leicht zu automatisieren durch die Verwendung von Fliehkraftregler .5. Easy to automate by using centrifugal governor.

6. Stufenlose Verstellung6. Stepless adjustment

Diese Erfindung kann bei Fahrräder,Motorräder, kleine Autos, Nebenantrieben und Industrie-Aggregaten verwendet werden. Eine besondere Zukunftverwendung sind die kleinen Elektro- und Ökoautos.This invention can be used in bicycles, motorcycles, small cars, auxiliary drives and industrial units. A particular future application is small electric and eco-cars.

Das Prinzip dieser Erfindung beruht auf die Verstellung der Riemenscheibe oder Kettenräder , d.h. daß der Durchmesser sich stufenlos vergrößern oder verkleinern kann.The principle of this invention is based on the adjustment of the pulley or sprockets, i.e. the diameter can be continuously increased or decreased.

Der Gegenstand der Erfindung besteht aus zwei Riemenscheiben oder Kettenräder,ein Zugmittelglied (Riemen oder Kette), Verstellungsmechanismus und zwei Umlenkrollen.The object of the invention consists of two pulleys or sprockets, a traction link (belt or chain), adjustment mechanism and two pulleys.

Die Verstellung erfolgt durch einen Kegel 3,der durch die Feder 12 in das Gehäuse 11 eingepresst ist. In diesem Fall fahren die Segmente 6 und die Bolzen 5 in ihrer höchsten Stellung.. mit dem Schalthebel 2,kann man die Lage der Segmente verändern.The adjustment is carried out by a cone 3, which is pressed into the housing 11 by the spring 12. In this case, the segments 6 and the bolts 5 move to their highest position. The position of the segments can be changed using the switching lever 2.

Eine vollautomatische Verstellung erfolgt auch nach Fig. mittels Fliehkraftregler 2 .A fully automatic adjustment is also carried out as shown in Fig. by means of centrifugal governor 2 .

Die Umlenkrollen 10 und 8 sowie die Feder 9 ,dienen dem Zweck das Zugmittelglied stramm zu halten.The pulleys 10 and 8 as well as the spring 9 serve the purpose of keeping the traction element taut.
