Estimating the term…
A belt tensioning device having a substantially cylindrical receiving housing and a hub coaxially arranged therein. The receiving housing and the hub are supported so as to be rotatable relative to one another as well as supported by a helical torsion spring so as to be pretensioned relative to one another. A damping device is provided which comprises a circumferentially slotted damping bush and a strip spring adapted to the damping bush, wherein the damping bush rests against the inside of the receiving housing. The strip spring is arranged between the damping bush and the torsion spring. The strip spring and the torsion spring are connected in series, wherein one of the two is supported on the receiving housing and the other one of the two on the hub.
