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

#CMT# #/CMT# 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. #CMT# : #/CMT# An independent claim is also included for a traction element drive for an internal combustion engine. #CMT#USE : #/CMT# For a traction element (belt) drive #CMT#ADVANTAGE : #/CMT# Enables the pretensioning force for the belt to be adapted to the respective operating cycle of the starter generator. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a tensioning system for a belt drive 21 : spring element 22, 23 : attachment element 24 : additional tensioning element 40 : base system 45 : membrane oscillator.
