Abstract
A damping device of a mechanical tensioning system for a traction mechanism drive for damping pivoting movements of a tensioning arm. The tensioning arm is supported at one end by a tensioning roller on a traction mechanism and is rotatably mounted at the other end on a positionally fixed housing part, which has an annular friction element. The periphery of the friction element is a friction lining which interacts with a friction surface of the housing part surrounding the friction element. A torsional spring connects the housing part and tensioning arm. The tensioning arm is acted on with a torsional moment, generating a continuous preload of the traction mechanism which is supported on the friction element and exerts a radially outwardly acting force on the friction lining. Also, surface contact means, which act on the friction lining, transmit radial force between the torsional spring and friction lining.
