Title:
TORSIONAL VIBRATION REDUCTION DEVICE
Document Type and Number:
Japanese Patent JP2017150575
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a torsional vibration reduction device which can improve damping performance by reducing a load in an axial line direction acting on an inertia body.SOLUTION: A torsional vibration reduction device 1 which is constituted of a planetary gear mechanism, and arranged in a fluid transmission device 3 comprises: a plate 21 which is arranged adjacently to the planetary gear mechanism, is provided so as to be capable of transmitting torque to a first rotary element 20, and is constituted so as to be capable of transmitting torque to one of an input-side member 9 and an output-side member 8; a clearance 22 formed between the plate 21 and a third rotary element 17; and through-holes 23, 24 formed at a position corresponding to the third rotary element 17 in a radial direction of the plate 21 while penetrating the plate 21 in a plate thickness direction, and opened at the clearance 22. The other of the input-side member 9 and the output-side member 8 and a second rotary element 18 can transmit torque.SELECTED DRAWING: Figure 1
