Abstract

The design is particularly intended for transmission of high loads for example on motor vehicles. It can be used to provide a fully automatic transmission for heavy vehicles unlike normal belt transmissions that are suitable only for small loads. The patent describes only the principle of operation which provides a control shaft operating with a continuously variable belt drive (1), a differential gear (2) and a worm gearing (3).

Description

Stufenlos regelbares Getriebe Die Erfindung betrifft ein stufenlos regelbares Gtriebe, insbesondere zum Übersetzen starker Kräfte zOBo bei Kraftfahrzeugen0 Ein stufenlos regelbares Getriebe ermöglichtdie volle Ausnutzung der Antriebsmaschine bei jeder Fahrgeschwindigkeit»Es ist bekannt, daß zur Übersetzung der Antriebskraft im Kfz neben dem herkömmlichen Schaltgetriebe entweder das Automatikgetriebe oder die -stufenlos regelbare Übersetzung durch Keilriemen verwendet werden, Das Automatikgetriebe nimmt dem Fahrzugfahrer lediglich die Arbeit des Schaltens, es ermöglicht aber nicht die volle Ausnutzung der Antriebsmaschine bei jeder Drehzahl oder Fahrgeschwindigkeit,Die direkte stufenlose Übersetzung durch Keilriemen ist deshalb nur begrenzt geeignet,weil sich durch sie nur geringe Kräfte übersetzen lassen. Sie ist deshalb für starke PKW's und LKW2s ungeeignet0 Der Erfindung liegt die Aufgabe zugrunde, das Einschalten verschiedener Gänge überflüssig zu machen0 und die Antriebsmaschine wahlweise zoBo bei Beschleunigung des Kfzts ständig mit der Drehzahl des größten Drehmomentes, oder bei gleichbleibender Geschwindigkeit des Kfzts die Antriebsmaschine mit der Drehzahl des geringsten Kraftstoffverbrauches laufen zu lassen Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß eine stufenlos regelbare Übersetzung als Steuerung über einen Schneckentrieb auf ein Differenzialgetriebe wirkt Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher besdhrieben, es zeigen: 1) Stufenlos regelbarer Keilriementrieb 2) Differenzialgetriebe 3) SchneckentriebInfinitely variable transmission The invention relates to a continuously variable transmission adjustable transmission, especially for transferring strong forces zOBo in motor vehicles0 A continuously variable transmission enables full utilization of the drive machine at any driving speed »It is known that to translate the driving force in the motor vehicle, in addition to the conventional manual gearbox, either the automatic gearbox or the -continuously variable transmission can be used by V-belts, the automatic transmission It only takes away the work of shifting from the driver of the vehicle, but does not enable it the full utilization of the prime mover at any engine speed or driving speed, the direct stepless transmission by V-belt is therefore only suitable to a limited extent because only small forces can be translated through them. It is therefore for the strong Cars and trucks unsuitable The invention is based on the task of switching on to make different gears superfluous0 and the drive machine optionally zoBo when the vehicle accelerates constantly at the speed of the greatest torque, or at the same speed of the motor vehicle the prime mover with the To run the speed of the lowest fuel consumption These The object is achieved according to the invention in that a continuously variable translation An exemplary embodiment acts as a control via a worm drive on a differential gear is shown in the drawing and is described in more detail below, it shows: 1) Infinitely variable V-belt drive 2) Differential gear 3) Worm drive
