Description
. Es sind Getriebe bekannt, bei denen die Übertragung von der treibenden auf die getriebene Welle nicht unmittelbar, sondern durch Leistungsverzweigung erfolgt. Bei diesen Getrieben wird ein Teil der Leistung durch unmittelbare Übertragung mittels Zahnräder, der andere Teil durch ein. Nebengetriebe in Verbindung mit einem Differentialgetriebe der getriebenen Welle zugeleitet.. There are known gears in which the transmission from the driving to the driven Wave does not take place immediately, but rather through a power split. With these gearboxes, part of the performance is by direct transmission by means of gears, the other part by a. Auxiliary transmission fed in connection with a differential gear of the driven shaft.
ίο Dient ein Stufenrädergetriebe als Nebengetriebe, so ist auch das Gesamtgetriebe nur in Stufen regelbar. Stufenlos regelbar ist das Getriebe, wenn als Nebengetriebe ein stufenloses, also zweckmäßig ein Flüssigkeitswechselgetriebe oder bei kleinen Leistungen ein Reibräderwechselgetriebe verwendet wird. Die Regelbarkeit dieser Getriebe ist abhängig von dem Drehzahlbereich des Nebengetriebes. Da die stufenlosen Getriebe nur in einem verhältnismäßig kleinen Ausschnitt ihres Drehzahlbereiches mit günstigem Wirkungsgrad arbeiten, so wird außerhalb dieses Ausschnittes auch der Wirkungsgrad des Gesamtgetriebes ungünstig.ίο If a stepped gear transmission is used as a secondary transmission, so the entire transmission can only be regulated in stages. It is infinitely variable Gearbox, if the secondary gearbox is a continuously variable, i.e. expediently a fluid change gearbox or a friction gear change gear is used for small powers. The controllability of this gear is dependent from the speed range of the auxiliary transmission. Since the continuously variable transmission only in a proportionate way If a small section of your speed range is working with a favorable degree of efficiency, then outside this section the efficiency of the entire transmission is also unfavorable.
Erfindungsgemäß wird neben einem beliebig großen Regelbereich ein annähernd gleich günstig bleibender hoher Wirkungsgrad bei stufenlosen Getrieben mit Kraftübertragung durch ein Stufenrädenvechselgetriebe in Verbindung mit einem Differentialgetriebe dadurch erreicht, daß die Stufensprünge, wie an sich bekannt, durch ein stufenlos regelbares Flüssigkeitswechselgetriebe überbrückt werden und dieses letztere, als Nebengetriebe. .According to the invention, in addition to an arbitrarily large control range, one is approximately the same Low-cost, high efficiency with continuously variable transmissions with power transmission by means of a step wheel change gear in connection with a differential gear achieved that the increments, as known per se, by a continuously variable Fluid change gears are bridged and this latter, as a secondary gear. .
ausgebildet, das Differentialgetriebe beeinflußt. Hierbei wird die Größe des Stufensprunges zweckmäßig so gewählt, daß das Nebengetriebe in seinem günstigsten Drehzahlbereich arbeitet. Die Verbindung von Stufengetriebe und Differentialgetriebe sowie insbesondere die. Anordnung des stufenlos regelbaren Flüssigkeitsgetriebes erfolgt je nach dem Verwendungszweck des Getriebes auf verschiedene Art. Das Differentialgetriebe kann sowohl hinter dem Stufenrädergetriebe als auch vor demselben angeordnet werden, ohne daß das Wesen der Erfindung geändert wird.formed that affects the differential gear. This is the size of the increment expediently chosen so that the secondary transmission is in its most favorable speed range is working. The connection of multi-step gear and differential gear as well as in particular the. Arrangement of the stepless controllable fluid transmission takes place depending on the intended use of the transmission in different ways. The differential gear can be both behind the stepped gear as well as in front of the same, without changing the essence of the invention will.
Eine Ausführungsform des Gegenstandes der Erfindung ist in der Zeichnung schematisch dargestellt.An embodiment of the subject matter of the invention is shown schematically in the drawing shown.
Von der treibenden Welle α wird die Kraft über Stufenräder c auf die Welle b übertragen. Zwischen dieser und der getriebenen Welle d, von der die Kraft abgenommen wird, ist ein Differentialgetriebe e angeordnet, welches von dem stufenlos regelbaren Nebengetriebe b bewegt wird. Das Nebengetriebe f verbindet zwei Glieder des Differentialgetriebes, in der dargestellten Ausführungsform die treibende Welle mit dem Planetenradträger. Die Drehzahl des Planeten radträge fs und damit die Drehzahl des Gesamtbetriebes kann durch Regeln des Nebengetriebes stufenlos verändert werden. Dient ein Flüssigkeitsgetriebe als Nebengetriebe, so erfolgt die Regelung in bekannter Weise durch Hubverstellung der Pumpe oder des Motors bzw. durchThe force is transmitted from the driving shaft α to the shaft b via step gears c . Between this and the driven shaft d, from which the power is taken, a differential gear e is arranged, which is moved by the continuously variable secondary gear b . The secondary gear f connects two members of the differential gear, in the illustrated embodiment the driving shaft with the planetary gear carrier. The speed of the planetary wheel inertia fs and thus the speed of the overall operation can be continuously changed by regulating the auxiliary gear. If a fluid transmission is used as a secondary transmission, the regulation takes place in a known manner by adjusting the stroke of the pump or the motor or by
