Title:
DYNAMIC DAMPER DEVICE AND LOCK-UP DEVICE OF TORQUE CONVERTER
Document Type and Number:
Japanese Patent JP2015094423
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dynamic damper device capable of suppressing generation of noise when an inertia member is largely fluctuated, and suppressing abrasion wear of the inertia member and a member against which the inertia member collides.SOLUTION: A dynamic damper device includes a damper plate portion 45, an inertia member 46, a damper mechanism 48, and a hysteresis torque generation mechanism 50. The damper plate portion 45 is an extended portion of a second plate 42 of an intermediate member 34. The inertia member 46 is rotatable relatively to the damper plate portion 45. The damper mechanism 48 connects the damper plate portion 45 and the inertia member 46 elastically in a rotating direction. The hysteresis torque generation mechanism 50 generates low hysteresis torque in a low twisting angle region of the damper plate portion 45 and the inertia member 46, and generates high hysteresis torque in a high twisting angle region.
