Description

Spannrollengetriebe. Der Gegenstand der Erfindung ist ein Spannrollengetriebe, bei welchem der Stellarm und der Spannrollenträger nachgiebig miteinander verbunden sind.Tension pulley transmission. The object of the invention is a tension roller gear, in which the actuating arm and the idler support are resiliently connected to one another are.

Die Erfindung bezweckt, bekannte Anordnungen dieser Art so zu verbessern, daß die Spannrolle ohne Überspannung des Riemens leicht und schnell bedient werden kann, wodurch die Anordnung, insbesondere für Kleinfahrzeuge, erhebliche Bedeutung erhält, da gerade hier der Regel nach ein mit großer Plötzlichkeit notwendiges Ein- und Ausschalten der Spannrolle auftritt und demzufolge eine Einrichtung, welche die Überbeanspruchung des Riemens in möglichst weitgehendem Maße verhindert, besonders erwünscht ist.The aim of the invention is to improve known arrangements of this type in such a way that that the tension pulley can be operated easily and quickly without over-tensioning the belt can, whereby the arrangement, especially for small vehicles, significant received, since it is precisely here that, as a rule, a sudden and disengagement of the tensioner pulley occurs and consequently a device which the overstressing of the belt is prevented to the greatest possible extent, especially is desirable.

Die Aufgak wird erfindungsgemäß dadurch gelöst, daß die Stellarmraste verstellbar angeordnet ist und in eine Normallage gebracht werden kann, welche durch Anschläge am Spannrollenträger bzw. am Stellarm bestimmt ist.The task is achieved according to the invention in that the actuating arm catch is adjustable and can be brought into a normal position, which by Stops on the tension roller carrier or on the actuating arm is determined.

In der Zeichnung ist- ein Ausführungsbeispiel der Anordnung gemäß der Erfindung schematisch dargestellt. Der Riemen r läuft über das Triebrad 2 und über die Spannrolle 3 zu einem nicht dargestellten weiteren Triebrade. Der Spannrollenträger 4 ist itm den Zapfen 5 beispielsweise am Gestell eines Kleinkraftwagens drehbar gelagert. Auf derselben Achse ist der Stellarm 6 drehbar angeordnet, welcher mit dem Spannrollenträger q. beispielsweise durch die Schraubenfeder 7 elastisch verbunden ist. Die verstellbar angeordnete Raste 8 kann mittels der Schrauben 9 und io in der eingestellten Lage festgehalten werden. z i ist der bekannte Rasthebel. Die am Spannrollenträger bzw. am Stellarm angebrachten Anschläge 12 und 13 sind federnd ausgebildet, beispielsweise derart, daß der Anschlag 12 starr und der Anschlag 13 am Stellarm durch eine Feder gebildet wird. Die Einstellung der Stellarmraste, welche die Stellung der gesamten Anlage bestimmt, ist nun derart zu treffen, daß in der Rastlage der federnde Anschlag 13 sich leicht gegen den Anschlag 12 legt. Durch diese Anordnung wird selbsttätig der richtige Spannrollendruck erzeugt, da auch bei gewaltsamer Einstellung des Steharmes der festliegende, von der Feder 7 ausgeübte Druck stets derselbe sein wird. Die Anordnung hat auch den besonderen Vorteil, daß eine Überanstrengung des Riemens durch zu festes Anpressen der Rolle auf diese Weise vermieden wird.In the drawing, an embodiment of the arrangement according to the invention is shown schematically. The belt r runs over the drive wheel 2 and over the tension roller 3 to a further drive wheel, not shown. The tension roller carrier 4 is rotatably mounted with the pin 5, for example on the frame of a small motor vehicle. On the same axis, the actuating arm 6 is rotatably arranged, which with the tension roller carrier q. is elastically connected for example by the helical spring 7. The adjustably arranged catch 8 can be held in the set position by means of the screws 9 and io. zi is the well-known locking lever. The stops 12 and 13 attached to the tension roller support or the actuating arm are designed to be resilient, for example in such a way that the stop 12 is rigid and the stop 13 is formed on the actuating arm by a spring. The setting of the actuating arm detent, which determines the position of the entire system, must now be made in such a way that the resilient stop 13 lies slightly against the stop 12 in the detent position. This arrangement automatically generates the correct tension roller pressure, since the fixed pressure exerted by the spring 7 will always be the same even if the upright arm is set by force. The arrangement also has the particular advantage that overexertion of the belt by pressing the roller too tightly is avoided in this way.
