Abstract
A tensioning device for a belt drive, especially for a V-belt drive for the drive of aggregates of an engine such as an internal combustion engine, with a fixed member and a member rotatable with respect thereto and carrying a tensioning roller resting against a belt, whereby a spring as well as a damping device having a damping force dependent on the operating condition which presses the tensioning roller against the belt, acts between the fixed and the rotatable part. In order to prevent a belt fluttering and a belt slippage in a defined manner, an additional damping device is provided between the rotatable and the fixed member or the engine which is controllable as a function of one or several operating parameters of the belt drive and/or of the engine and is operable only at certain values of these operating parameters.
