Abstract
A tensioner for a traction member, in particular a belt of a traction drive for an internal combustion engine, includes a base constructed for rotation about a rotation axis and having a pivot arm. The pivot arm has a free end for connection of a rotatable tension roller which bears against a traction member. A spring member urges the pivot arm to seek a forced engagement of the tension roller upon the traction member. Disposed between the base and the pivot arm is a damping element for damping an adjusting movement of the pivot arm. A pivot bearing supporting one portion of the base on a machine part for rotation about the rotation axis, whereby the rotation of the base in relation to the machine part is realized by an actuator to thereby adjust a biasing force of the traction member.
