Abstract

A traction device for an internal combustion engine includes a tensioning device having two lever arms of different lengths which are rigidly connected together and which are pivotally mounted for rotation about a rotation axis. Each of the lever arms supports on one end a tension pulley. The tensioning device is provided for positioning the tension pulleys on a pulling strand and a return strand by imposing an elastic force thereon.
