DAMPER DEVICE WITH DYNAMIC VIBRATION ABSORBER

Japanese Patent JP2017020529

A

PROBLEM TO BE SOLVED: To provide a damper device with a dynamic vibration absorber which is compact in size without increasing the number of part items of the damper device.SOLUTION: A damper device with a dynamic vibration absorber comprises: a first elastic member 74 which is arranged between a first rotating body 71 and a second rotating body 72, and connects the first rotating body and the second rotating body so as to be transmittable in power between them; and a second elastic member 75 which is arranged between the first rotating body and the second rotating body, and also arranged between either of the first rotating body and the second rotating body and a dynamic vibration absorber inertia body 73. When relative displacement θx being the displacement of the first rotating body with respect to the second rotating body is smaller than a prescribed amount θa, the second elastic member does not connect the first rotating body and the second rotating body, constitutes a dynamic vibration absorber by connecting either of the first rotating body and the second rotating body and the dynamic vibration absorber inertia body, and when the relative displacement is larger than the prescribed amount, connects the first rotating body and the second rotating body so as to be transmittable in power between them.SELECTED DRAWING: Figure 1
