    • A tensioning device for a traction mechanism drive, in particular for a belt drive. The tensioning device can be produced in an advantageous manner from production and design aspects and which offers advantages over known concepts with regard to the wear of the friction surface element in that it has a base part, having a pivot arm, having a torsion spring, which is designed as a coil spring, for imparting a pivoting torque which acts between the base part and the pivot arm and which forces the pivot arm in a tensioning direction, and having a damping device for generating a damping force which counteracts a pivoting movement of the pivot arm counter to the tensioning direction. The damping device includes a friction surface element which, as such, forms a friction surface which serves to impart a friction force, and which is seated on a mating friction surface, wherein the friction surface element is designed as a ring-shaped or ring-segment-shaped component and is forced outward, in a radial direction with respect to the pivot axis, against the mating friction surface by the torsion spring, and wherein the torsion spring has a coil end section which bears against an inner surface of the friction surface element. The torsion spring is designed, at least in the coil end section which bears against the inner surface of the friction surface element, with regard to the spring cross section such that said coil end section is in areal contact with the inner surface of the friction surface element.

    • A tensioning device for a traction mechanism drive for a belt drive that is incorporated in an internal combustion engine, in order to drive components of the engine or installed accessories. The tensioning device has a construction that is advantageous under production and construction viewpoints, by a high degree of robustness, and also by an advantageous mechanical operating behavior. The tensioning device includes a base part, a swivel arm, a torsion spring with a first winding end section that is allocated to the swivel arm and a second winding section that is allocated to the base part for applying a pivoting moment acting between the base part and the swivel arm and forcing the swivel arm in a tensioning direction, and a damping device for generating a damping force that counteracts a pivoting of the swivel arm directed against the tensioning direction. This damping device includes a first friction surface element that is arranged in a region of the winding end section of the torsion spring allocated to the swivel arm, and forms a friction surface that is used for applying friction force and that sits on a counter friction surface. In the region of the second winding end of the torsion spring for the base part, there is a second friction surface element that forms a friction surface that sits on a counter friction surface, and the counter friction surface is formed by a friction surface structure that can pivot together with the swivel arm.
