ABSTRACT:
A tensioning arrangement for a drive belt includes a support, a tension roller rotatably mounted on one end of the support, a swivel bearing arranged on the support at a distance from the tension roller, a swivel-damping element in the form of a linear-acting frictional damper having a master piston and a slave piston arranged in and separately frictionally engaging a cylinder, a spring arranged concentrically around the cylinder and coupled to the master piston, and a spring arranged inside the cylinder and coupled to the slave piston. The displacement of the master piston in one direction is opposed by the frictional forces separately acting on both pistons, whereas the displacement of the master piston in the other direction is opposed by the frictional forces acting on only the master piston.
