Abstract

Die vorliegende Erfindung betrifft eine Riemenscheibe, die um eine Drehachse (D) drehbar ist, mit einer Auflagefläche (4) für einen Riemen sowie einem ersten und einem zweiten Bauteil (11, 12) von denen eines eingangsseitig und das andere ausgangsseitig angeordnet ist, wobei das erste und das zweite Bauteil (11, 12) relativ zueinander verdrehbar sind und wobei zwischen dem ersten und dem zweiten Bauteil (11, 12) eine Feder (2) wirkt, welche bei einer drehenden Relativbewegung von erstem und zweitem Bauteil (11, 12) verformt wird. Die Erfindung ist dadurch gekennzeichnet, dass ein Freigang vorgesehen ist, der es ermöglicht, das erste und das zweite Bauteil (11, 12) relativ zueinander über einen begrenzten Winkelbereich zu verdrehen, ohne dass die Feder (2) dabei verformt wird.The present invention relates to a pulley, which is rotatable about a rotation axis (D), with a support surface (4) for a belt and a first and a second component (11, 12) of which one on the input side and the other output side is arranged the first and the second component (11, 12) are rotatable relative to each other, and wherein between the first and the second component (11, 12) a spring (2) acts, which in a rotating relative movement of the first and second component (11, 12 ) is deformed. The invention is characterized in that a clearance is provided, which makes it possible to rotate the first and the second component (11, 12) relative to each other over a limited angular range, without the spring (2) being deformed.
