Tensioning device for traction unit e.g. belt or chain, has spring element such as torsion spring or leg spring, pre-stressing clamping lever and arranged position firmly at clamping lever, where spring element aids clamp-dampening-element

摘要

The device has a clamping lever (8) arranged rotatably at a third article e.g. engine mount, around an axis (10) and including a clamping unit (15) such as tensioning pulley for a traction unit (2). A clamp-dampening-element (16) is arranged at the third article and at the clamping lever. A spring element e.g. torsion spring or leg spring, pre-stresses the clamping lever and is arranged position firmly at the clamping lever. The spring element aids the clamp-dampening-element.
