Title:
CENTRIFUGAL PENDULUM VIBRATION ABSORBER AND DEGREE-SETTING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/103661
Kind Code:
A1
Abstract:
The degree of vibration of a mass body (12x) in a centrifugal pendulum vibration absorber positioned inside a fluid-transmission chamber for storing a working fluid is set on the basis of the degree of the vibrations which should be attenuated and are produced by an engine serving as a drive device, and in consideration of the force (Fp) acting on the mass body (12) as a result of centrifugal pressure produced inside the fluid-transmission chamber (2) and corresponding to the rotations of a rotating element connected to the centrifugal pendulum vibration absorber. As a result, it is possible to improve vibration absorption performance by more appropriately setting the degree of vibration of a mass body in a centrifugal pendulum vibration absorber positioned inside a fluid chamber for storing a fluid.
