Rotating drive clamping device i.e. belt tightener, for engine in vehicle, has auxiliary accumulator with spring stiffness larger than spring stiffness of main accumulator and deflected within operating area by forces of rotating drive

摘要

#CMT# #/CMT# The device (1) has a clamping part (3) relative-movably supported at a base part (2). A main operating energy accumulator (5) and an auxiliary energy accumulator (6) are connected in a row. The clamping part is supplied with energy by the accumulators. The main accumulator is movable up to a predetermined maximum within an operating area by operating forces of a rotating drive. The auxiliary accumulator exhibits spring stiffness larger than a spring stiffness of the main accumulator. The auxiliary accumulator is deflected within the operating area by operating forces of the drive. #CMT# : #/CMT# An independent claim is also included for an operating method for a rotating drive clamping device for clamping a rotating drive of an engine. #CMT#USE : #/CMT# Rotating drive clamping device i.e. belt tightener, for clamping a rotating drive of an engine in a vehicle. Can also be used for an axial tightener and rotated working tightener. #CMT#ADVANTAGE : #/CMT# The main operating energy accumulator and the auxiliary energy accumulator can support each other, where the spring stiffness of the auxiliary accumulator is larger than the spring stiffness of the main accumulator, thus ensuring better operational characteristics with simple structure and noiseless operation of the device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a rotating drive clamping device. 1 : Rotating drive clamping device 2 : Base part 3 : Clamping part 5 : Main operating energy accumulator 6 : Auxiliary energy accumulator.
