Title:
VIBRATION DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/199324
Kind Code:
A1
Abstract:
A vibration damping device including: a support member that rotates around the rotation center of a rotating element; a restoring force generation member coupled to the support member; and an inertia mass body coupled to the support member via the restoring force generation member. The restoring force generation member includes two guided sections arranged in the circumferential direction of the rotating element and having an interval therebetween; and a torque transmission section arranged between the two guided sections and exchanging torque with the support member. The inertia mass body includes a plurality of guide sections that guide corresponding guided sections. The guided sections are guided by the guide sections such that, when the support member rotates, the restoring force generation member swings along the radial direction relative to the rotation center and the inertia mass body swings around the rotation center. The centrifugal force component that acts on the restoring force generation member is transmitted to the inertia mass body via the guide sections.
