Title:
TORSIONAL DAMPER DEVICE
Document Type and Number:
Japanese Patent JP2017015258
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a torsional damper device in which its eccentricity at the time of low speed of a heat engine is avoided and a filtering performance is not lost.SOLUTION: This invention comprises a supporting member 2 rotatable around its axis, at least one pendulum main body rotatable against the supporting member 2, at least one rolling orbit for guiding a motion of the pendulum main body and at least one rolling member 11 cooperating with at least one rolling orbit 12 connected to the pendulum main body. At least one of the rolling orbits 12, 13 extends between the two end parts. The first portion extending from a rest position to at least one side in this rolling orbit has a shape in which a twisting vibration of a first dimension can be filtered by the pendulum main body 3, includes the second two portions arranged to extend over one end of the first part and has a shape in which a twisting vibration of second dimension can be filtered by the pendulum main body 3 and the second dimension is smaller than the first dimension.SELECTED DRAWING: Figure 2
