Abstract:
A belt drive of an internal combustion engine, comprising:a first pulley mounted onto a crankshaft of the internal combustion engine; a second pulley mounted to a shaft of a starter generator of the internal combustion engine; a belt looped about the first and second pulleys; and a tensioner having two tensioning rollers and two tensioning arms, wherein the tensioning arms pivot about a common rotation axis, one of the tensioning arms supporting one of the tensioning rollers and applying a force upon one belt run of the belt so as to bias the one tensioning roller against the belt run, and the other one of the tensioning arms supporting the other one of the tensioning rollers and applying a force upon another belt run of the belt so as to bias the other tensioning roller against the belt run, and wherein the tensioning arm disposed in the belt run operating as the load-carrying run is urged by a resultant belt force into a stop position in which the resultant belt force extends, at least approximately, in alignment with the tensioning arm.
