Description

Sohlinsfederfreilauf für beide Drehrlchtungen Sole spring freewheel for both directions of rotation

Das Gebrauchsmuster soll eine selbstumschaltende Freilauffunktion für beide Drehrichtungen bewirken. Ein Anwendungsfall ist z.B. bei ketteixgetriebenen Kinderfahrzeugen gegeben, mit Freilauf in Vorwärts- und Rückwärtsrichtung.The utility model is intended to bring about a self-switching free-wheeling function for both directions of rotation. One application is e.g. given in ketteix-driven children's vehicles, with freewheel in Forward and backward direction.

Bekannt ist hierfür ein Freilauf mit Klemmgesperre für beide Drehrichtungen. Demgegenüber werden bei dem Gebrauchsmuster zwei gleiche Schlingfederkupplungen für Rechts- und Linkslauf benutzt.A freewheel with locking mechanism for both is known for this Directions of rotation. In contrast, two identical wrap spring clutches are used for clockwise and counterclockwise rotation in the utility model.

In der Zeichnung ist das Gebrauchsmuster beispielsweise dargestellt, es besteht aus zwei gleichen, spiegelbildlich angeordneten Teilen.In the drawing, the utility model is shown, for example, it consists of two identical, mirror-inverted parts.

Nach Zeichnung ist 1 die Antriebsnabe mit Antriebselement (Kettenrad), lose gelagert auf der Abtriebswelle. Geringfügig kleiner im Durchmesser ist der Zylinder 2, der fest mit der Abtriebswelle verstiftet ist.According to the drawing, 1 is the drive hub with drive element (sprocket), loosely mounted on the output shaft. Slightly smaller in diameter is the cylinder 2, which is fixed to the output shaft is pinned.

Die Schlingfeder 3 besitzt zwei angebogene Enden, das innere ist in einem Schlitz an der Antriebsnabe eingehängt, das äußere Betätigungsende ist in der verdrehbaren Außenhülse 4- eingehängt. Durch die Druckfeder 5 wird die Reibscheibe 6, die auf der festen Stange 7 gelagert ist, gegen die Außenhülse gedrückt und erzeugt an der Außenhülse ein Haltemoment, das größer ist, als das Verdrehmoment der Schlingfeder.The wrap spring 3 has two bent ends, the inner one hung in a slot on the drive hub, the outer actuating end is suspended in the rotatable outer sleeve 4-. The friction disk 6, which is on the fixed rod 7 is mounted, pressed against the outer sleeve and generates a holding torque on the outer sleeve that is greater than the twisting torque the coil spring.

Dreht z.B. die Antriebsnabe im Schnitt A-B entgegen Uhrzeigersinn, wird das äußere Betätigungsende der Schlingfeder solange gehalten, bis die Windungen auf dem Zylinder 2 anliegen, um dann mit dem Abtrieb mitzudrehen. Auf der gegenüberliegenden Kupplung gibt es keine Relativbewegung zwischen Antriebsnabe und Außenhülse, da in dieser Richtung die Außenhülse über den Anschlag 8 der Antriebsnabe mitgenommen wird. Beim Übergang in den Freilaufzustand wird die anliegende Schlingfeder von dem weiterdrehenden Zylinder 2 bis unter das Haltemoment gelöst.Rotates e.g. the drive hub in section A-B counterclockwise, the outer actuating end of the wrap spring is held until the windings rest on the cylinder 2 to then with the To turn the output. On the opposite coupling there is no relative movement between the drive hub and the outer sleeve, since in in this direction the outer sleeve is taken along via the stop 8 of the drive hub. During the transition to the freewheeling state, the attached wrap spring is released from the cylinder 2, which continues to rotate, to below the holding torque.

Das Haltemoment, das maximal zweimal als Verlust auftritt, wird durch eine niedrige Verdrehsteifigkeit der Schlingfeder klein gehalten.The holding torque, which occurs as a loss at most twice, is small due to the low torsional stiffness of the wrap spring held.
