<p>The invention relates to a tensioning device (11) for a traction mechanism drive (1) which is arranged on an internal combustion engine and comprises a drive wheel (3) arranged on a drive shaft (30) of an engine (4), one or more additional driving wheels (5, 6), and a continuously revolving traction means (2), which wraps around the drive wheel and the additional driving wheels. The tensioning device comprises two tensioning arms (13, 14) having tensioning wheels (9, 10) mounted thereon, which apply a tensioning force to the traction means in front of and behind the drive wheel in the direction of revolution, and is provided with a spring means (16) generating the tensioning force, and a tensioner housing (12), which movably mounts at least one of the tensioning arms to which the force of the spring means is applied. The tensioner housing is mounted on the engine pivotably about the axis (29) of the drive shaft.</p> |
