Abstract

The present disclosure describes a variable belt tensioner of an internal combustion engine for adjusting a belt tensioning. The tensioner includes in a series configuration an electric motor, a worm drive, a lever drive and a belt tensioner roller. The worm drive is driven by the electric motor and is mechanically connected to the lever drive for transmitting a rotation thereto. The lever drive is mechanically connected to the belt tensioner roller for transmitting a translation thereto, thus allowing the belt tensioner roller to adjust the belt tensioning.
