Description

  

  Sperrbarer Freilauf.    Gegenstand der Erfindung ist ein sperr  barer Freilauf. Dieser ist in     Fig.    1 und 2 der  Zeichnung in zwei Schnitten in einem Beispiel  dargestellt.  



  Ein mehrkantiger Wellenteil A ist in  einem Zylinder B zentrisch gelagert; zwi  schen den Abflachungen des Teils A und der  Zylinderwand sind Walzen C eingeschoben,  die in ihrer Mittelstellung etwas radiales       Spiel    haben. In dem Teil     A.        sind    Schieber<I>D</I>  eingelassen, die vom zentralen Hohlraum des  Teils A aus betätigt werden. Sind die Schie  ber nach aussen gestossen, so können sich die       U'alzen    in der Drehrichtung des Zylinders  gegen den Uhrzeigersinn nicht mehr fest  klemmen, der Freilauf ist eingeschaltet. Wer  den die Schieber nach innen gezogen, so tritt  in der betreffenden Drehrichtung Starrlauf       ein.     



  Die Betätigung der Schieber erfolgt durch  einen zentralen, in einer Bohrung des Teils A  untergebrachten Schiebekonus E, in dessen  ausgefrästen     T-Nuten    die Schieber geführt  werden. Mittels Federdruck werden der Ko-         nus    E in der Pfeilrichtung und damit die       Schieber    D radial nach aussen gedrückt. Der  Freilauf ist dadurch hergestellt. Beim Hin  eindrücken des Konus E gegen die Kraft der  Feder werden auch die Schieber D nach in  nen gezogen und geben dadurch die Walzen  C frei; dadurch entsteht Starrlauf.



  Lockable freewheel. The invention is a lockable freewheel. This is shown in Fig. 1 and 2 of the drawing in two sections in an example.



  A multi-edged shaft part A is mounted centrally in a cylinder B; Between tween the flats of part A and the cylinder wall, rollers C are inserted, which have some radial play in their central position. Slides <I> D </I> which are operated from the central cavity of part A are embedded in part A. Once the slides have pushed outwards, the U 'rollers can no longer jam in the counterclockwise direction of rotation of the cylinder, and the freewheel is activated. Anyone who pulls the slide inward will result in rigid running in the relevant direction of rotation.



  The slide is actuated by a central slide cone E accommodated in a hole in part A, in whose milled T-grooves the slide is guided. By means of spring pressure, the cone E is pressed in the direction of the arrow and thus the slide D is pressed radially outwards. The freewheel is thereby established. When the cone E is pushed in against the force of the spring, the slide D is also pulled inwards, thereby releasing the rollers C; this results in rigid running.

 

Claims (1)

PATENTANSPRUCH: Sperrbarer Freilauf, dadurch gekennzeich net, dass ein mehrkantiger Wellenteil mit einer Bohrung versehen und in einem Zylin der gelagert ist, und dass zwischen den Ab- flachungen des Wellenteils und der Zylinder wand Walzen eingeführt sind, die bei ge sperrtem Freilauf in beiden Drehrichtungen Starrlauf zwischen Wellenteil und Zylinder bewirken, und dass ferner durch Schieber, die von einem zentralen, in der genannten Boh rung angeordneten Schiebekonus aus betätig- bar sind, die Walzen nach Bedarf am Fest klemmen in einer Drehrichtung verhindert werden können. PATENT CLAIM: Lockable freewheel, characterized in that a multi-edged shaft part is provided with a bore and is stored in a cylinder, and that between the flattened areas of the shaft part and the cylinder wall, rollers are inserted which, when the freewheel is locked, in both directions of rotation Cause rigid running between the shaft part and the cylinder, and that furthermore, the rollers can be prevented from jamming in one direction of rotation by slides which can be actuated from a central sliding cone arranged in the said bore.
