Abstract
In a spring biased tension arrangement for transmission belts, a friction element is installed coaxial with respect to the pivot bearing. The friction element provides a turning direction dependent damping of the pivot arm. It may be disc or sleeve shaped and is inserted in an annular space to contact a limit surface with rubbing contact. Tongues or spoke elements, inclined to the turning direction, have inclinations dependent more or less elastically upon the turning direction and act for example to change the overall height or thickness of the friction element and therewith an increase of the friction force. The tongues or spoke elements can be connected with a separate spring or formed as a unit with the friction element.
