Title:
DAMPER DEVICE AND METHOD FOR DESIGNING SAME
Document Type and Number:
WIPO Patent Application WO/2020/059632
Kind Code:
A1
Abstract:
This damper device includes: an input element connected to an engine via a clutch; a middle element; an output element connected to an input shaft of a transmission; a first elastic body arranged between the input element and the middle element; and a second elastic body which is arranged between the middle element and the output element and acts in series with the first elastic body, wherein, when J2 is the total moment of inertia of the output element and a rotary element integrally rotating with the output element and closer to the engine than the input shaft, and JTM is the total moment of inertia of all rotary members between the input shaft and a differential gear connected to the output shaft of the transmission, the relation 0.12 ≤J2/(J2+JTM)≤0.5 is satisfied.
