Description
Der im Patentanspruch 1 angegebenen Erfindung liegt das Pro blem zugrunde, bei sich änderndem Abtriebsmoment eine stete automatische Anpassung der Übersetzung in solcher Weise zu erreichen, daß die Antriebsmaschine mit nahezu konstantem Antriebsmoment belastet wird.The invention specified in claim 1 is the pro blem underlying, a constant with changing output torque automatic adaptation of the translation in such a way too achieve that the prime mover with almost constant Drive torque is loaded.
Für muskelkraftbetriebene Fahrzeuge, wie z. B. Fahrrädern, ist dies besonders wichtig, da die als individuell angenehme Belastung in einem engen Rahmen liegt.For muscle powered vehicles, such as B. bicycles, this is particularly important, as that is individually pleasant Load is in a narrow range.
Das Nenneingangsdrehmoment sollte so auch individuell ein stellbar sein, so daß jeweils der günstigste Wirkbereich der antreibenden Person oder Maschine erfaßt wird.The nominal input torque should also be set individually be adjustable so that the cheapest effective range of each driving person or machine is detected.
Ferner ist es von Vorteil, wenn sich die Übersetzung nicht nur am Drehmoment, sondern an der Abtriebsdrehzahl orien tiert, z. B. in der Weise, daß die Übersetzung i = Antriebs drehzahl/Abtriebsdrehzahl proportional zur Abtriebsdrehzahl steigend beeinflußt wird.It is also an advantage if the translation is not correct only on the torque, but on the output speed animals, e.g. B. in such a way that the translation i = drive speed / output speed proportional to the output speed is increasingly influenced.
Wird der Einfluß dieser drehzahlabhängigen Regelung ein stellbar gestaltet, so ergibt sich die Möglichkeit, den jeweiligen Anforderungen und Fähigkeiten der Antriebsmaschi ne bzw. -person Rechnung zu tragen.Will the influence of this speed-dependent regulation designed adjustable, so there is the possibility of respective requirements and capabilities of the drive machine ne or person to take into account.
Die bisher aufgeführten Merkmale bzw. Anforderungen sind in der in Patentanspruch 1 angegebenen Erfindung vereinigt. Durch die Gestaltung, vor allem nach Patentanspruch 1 und 2, ist ein kompakt bauendes Getriebe möglich.The characteristics and requirements listed so far are in the invention specified in claim 1 combines. Through the design, especially according to claim 1 and 2, a compact gearbox is possible.
Ein Ausführungsbeispiel ist in der Zeichnung (Fig. 1) darge stellt, und wird im folgenden näher beschrieben:An embodiment is shown in the drawing ( Fig. 1) Darge, and is described in more detail below:
Fig. 1 zeigt das Getriebe in der kleinsten Übersetzung i. Der Antrieb erfolgt über die Antriebswelle (1.5). Fig. 1 shows the transmission in the smallest ratio i. It is driven by the drive shaft ( 1.5 ).
Der Kern des Getriebes ist das in Anspruch 1 aufgeführte Getriebebegehäuse (1.0), das drehbar auf der Drehmomentstüt ze (1.1) gelagert ist und das Stellgetriebe (1.2) enthält. The core of the transmission is the gear housing ( 1.0 ) listed in claim 1, which is rotatably mounted on the torque support ze ( 1.1 ) and contains the actuating gear ( 1.2 ).
Bei Drehung des Gehäuses (1.0) infolge einer Drehmomentände rung wird gemäß Anspruch 2 durch die zwischen Stellgetriebe (1.2) und Drehmomentstütze (1.1) angeordnete Verstellvor richtung (2.0) die Übersetzung zwischen in Anspruch 1 beschriebener Eingangswelle (1.3) und Ausgangswelle (1.4) geändert, wobei das Drehmoment von den in Anspruch 3 sowie Anspruch 4 beschriebenen Elementen (3.0) und (4.0) unter entsprechender Verformung in die Drehmomentstütze (1.1) geleitet wird. Dabei wird das Teildrehmoment an (4.0) über das hier drehbar angeordnete und fixierbare Bauteil (4.1) beschrieben in Anspruch 4, geleitet. Die Vorspannung kann so gegen eine Endlage des Getriebes (1.2) individuell einge stellt werden. Da die Elemente (3.0) und (4.0) parallel geschaltet sind, läßt sich somit die Gesamtfederrate der Elemente verändern.When the housing ( 1.0 ) rotates as a result of a torque change, the ratio between the input shaft ( 1.3 ) and the output shaft ( 1.4 ) described in claim 1 is changed by the adjusting device ( 2.0 ) arranged between the actuating gear ( 1.2 ) and the torque support ( 1.1 ) , wherein the torque from the elements ( 3.0 ) and ( 4.0 ) described in claim 3 and claim 4 is conducted with corresponding deformation into the torque arm ( 1.1 ). The partial torque at ( 4.0 ) is directed via the rotatably arranged and fixable component ( 4.1 ) described in claim 4. The preload can be set individually against an end position of the gearbox ( 1.2 ). Since the elements ( 3.0 ) and ( 4.0 ) are connected in parallel, the total spring rate of the elements can be changed.
Das Getriebegehäuse (1.0) entspricht also einer einstellba ren Drehmomentwaage. Wie in Anspruch 5, 8 und 9 dargelegt, wirkt die Kraft, resultierend aus der Drehzahl der Abtriebs welle (1.6), hier mechanisch durch Fliehkräfte, der an Hebeln (5.0) am Außenumfang angebrachten Gewichte (5.1) und einer verschieblich auf den Hebeln, diese umschlingende Ringfeder (5.2), entsprechend über ein geeignetes Getriebe (8.0), hier über ein beidseitig wirkendes Axiallager auf eine Hohlwelle, verdrehfest am Gehäuse (1.0) verschieblich angeordnet, auf die in Anspruch 8 genannten Hülse, so daß die Übersetzung auch drehzahlabhängig ist. Die verschieblich angeordnete Ringfeder (5.2) dient der gewünschten indivi duellen Einflußstärke der Abtriebsdrehzahl und ist hier durch entsprechende Rastungen auf den Hebeln gegen unbeab sichtigtes Verschieben gesichert.The gearbox ( 1.0 ) therefore corresponds to an adjustable torque scale. As set out in claims 5, 8 and 9, the force resulting from the speed of the output shaft ( 1.6 ) acts mechanically here by centrifugal forces, the weights ( 5.1 ) attached to levers ( 5.0 ) on the outer circumference and one which is displaceable on the levers, this looping ring spring ( 5.2 ), correspondingly via a suitable gear ( 8.0 ), here via a double-acting thrust bearing on a hollow shaft, rotatably arranged on the housing ( 1.0 ) so as to be displaceable, on the sleeve mentioned in claim 8, so that the translation is also speed-dependent . The displaceably arranged ring spring ( 5.2 ) serves the desired individual influence of the output speed and is secured here against accidental shifting by means of corresponding catches on the levers.
Gemäß Anspruch 6 ist das Getriebe über die Anschlußwellen (1.5) und (1.6) mit dem Planetengetriebe verbunden, um durch Leistungsverzweigung eine Stellbereichserweiterung, je nach Zähnezahlverhältnissen bis unendlich, zu erhalten und das Stellgetriebe (1.2) zu entlasten. Wie in Anspruch 7 angege ben, ist zum Schutz des Antriebs (Maschine oder Person) ein in Antriebsrichtung angeordneter Freilauf (7.0) in der Antriebsachse (1.5) gegenüber der Drehmomentstütze (1.1) angeordnet. Je nach Anwendung ist ein zweiter Freilauf in die Antriebsrichtung hinter die Abtriebswelle (6.0) und vor weiterem Anschlußglied, wie z. B. dargestellte Nabe zu set zen. Gegebenenfalls ist ein Freilauf gegen die Antriebsrich tung vor die Antriebsachse zu setzen, damit eine freie Wähl barkeit der Winkelstellung des Antriebsgliedes möglich ist.According to claim 6, the gearbox is connected to the planetary gearbox via the connecting shafts ( 1.5 ) and ( 1.6 ), in order to obtain a range extension, depending on the number of teeth, up to infinity, and to relieve the actuator ( 1.2 ) by branching out. As indicated in claim 7, in order to protect the drive (machine or person) a freewheel ( 7.0 ) arranged in the drive direction is arranged in the drive axis ( 1.5 ) opposite the torque arm ( 1.1 ). Depending on the application, a second freewheel is in the drive direction behind the output shaft ( 6.0 ) and in front of another connecting element, such as. B. illustrated hub to set zen. If necessary, a freewheel is to be set against the drive direction in front of the drive axle so that the angular position of the drive element can be freely selected.
