Title:
TORSIONAL VIBRATION REDUCTION DEVICE
Document Type and Number:
Japanese Patent JP2020133691
Kind Code:
A
Abstract:
To provide a torsional vibration reduction device which can expand a rotatable region of a planetary rotating element to a drive side at which the planetary rotating element rotates when engine torque is inputted thereto by a simple constitution.SOLUTION: In a torsional vibration reduction device 1 in which window hole parts 30, 31, 32 and 33 in which elastic bodies 28, 29 are assembled to an input element 23 and an output element 20 of a planetary rotating mechanism 19 are formed, and vibration is generated at the rotation of an inertia element 21 due to the torsional rotation of the input element 23 and the output element 20 by the vibration of engine torque, a first region A in which the planetary rotating element 22 can move to a drive side from a reference position NP by an input of the engine torque out of a region in which the planetary rotating element 22 reciprocally rotates by the vibration of the engine torque is set larger than a second region B in which the planetary rotating element 22 can move to a driven side from the reference position NP.SELECTED DRAWING: Figure 3
