Title:
DYNAMIC VIBRATION REDUCER FOR VEHICLE
Document Type and Number:
Japanese Patent JP2016133195
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dynamic vibration reducer which effectively reduces torque fluctuation of a turbine of a torque converter.SOLUTION: A dynamic vibration reducer 7 is provided at a turbine 15 of a torque converter 1. The dynamic vibration reducer includes: a damper plate 51; an inertia ring 57; and a third torsion spring 60. The damper plate 51 is fixed to the turbine 15 and rotates around a rotation center O. The inertia ring 57 has a first window part 66 and a second window part 76. The inertia ring 57 rotates around the rotation center O relative to the damper plate 51 to damp torque fluctuation of the turbine 15. The third torsion spring 60 is held by the first window part 66 and the second window part 76. The third torsion spring 60 elastically connects the damper plate 51 with the inertia ring 57 in a rotation direction. The third torsion spring 60 slides on the first window part 66 and the second window part 76 to generate hysteresis torque.SELECTED DRAWING: Figure 4
