Tensioning device for combustion engine belt drive forms tensioning/supporting force with pressure fluid provided via base system acting as active pressure source to operate additional tensioning element as active tensioning/damping element

摘要

The tensioning device has at least one tensioning roller that is applied to the belt, a spring element (21) and an additional tensioning element (24), whose tensioning or supporting force is formed by a pressure fluid provided via a base system (40) functioning as an active pressure source. to operate the additional tensioning element as an active tensioning or damping element. An independent claim is also included for a traction element drive for an internal combustion engine.
