A belt tensioning device for a continuous belt drive. The device includes a torsion spring assembly () with a longitudinal axis (A) and with at least one torsion bar or torsion tube (). The torsion spring assembly () can be clamped axially and in a rotationally fast way into a rack. A tensioning arm (), at one end, is arranged at the torsion spring assembly () so as to be aligned approximately radially relative to the longitudinal axis (A). A tensioning roller () is rotatably fixed at the other end of the tensioning arm (). The axis of rotation (A) of the tensioning roller () extends substantially parallel relative to the longitudinal axis (A) of the torsion spring assembly (), and the tensioning arm () can be resiliently supported relative to the rack so as to oscillate around the longitudinal axis (A).

Belt tensioning device

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.

Tensioning device for a belt-driven starter-generator

A drive belt of an internal combustion engine has a first pulley mounted on a crankshaft of the internal combustion engine, and a second pulley mounted on a shaft of a starter generator of the internal combustion engine. A belt is looped about both pulleys. A tensioner includes two tensioning arms, each of which loading a belt run of the belt and operating either as load-carrying belt run or non-load carrying belt run. Both tensioning arms are disposed to pivot about a rotation axis, with tensioning rollers mounted onto the tensioning arms and spring-biased against the belt. The tensioning arm disposed respectively upon the load-carrying belt run is urged into a stop position by a force applied by the belt.
