摘要： A rotary inertia mass damper of a damper device is configured to include a planetary gear that includes a driven member with outer teeth, first and second input plate member as a carrier which rotatably supports a plurality of pinion gears, and a ring gear that meshes with the plurality of pinion gears and works as the mass body. The outer teeth of the driven member are arranged to be disposed outside first and second springs in a radial direction of the damper device. The driven member, the plurality of pinion gears and the ring gear are arranged to at least partially overlap with the first and second springs as viewed in the radial direction. A motion of the ring gear in the axial direction is restricted by the plurality of pinion gears.

摘要： Six through holes are formed in pinion gear supporting portions of two input plate members working as a carrier that supports pinion gears of a rotary inertia mass damper. The two input plate members are opposed to each other in such a manner that the through holes are aligned with each other. The through holes support the pinion gear. The input plate members are coupled with each other by means of rivets passing through the through holes located on both sides of the through holes. This configuration ensures strength (rigidity) of the carrier, suppresses deformation of a planetary gear, and improves meshing accuracy of gears.

摘要： An intermediate member is configured to include first and second intermediate members. Connecting portions that respectively extend outward from the first or the second intermediate plates are coupled with each other at two positions on the same circumference as pinion gears by two rivets (total six rivets at three connecting portions) as viewed in a central axis of the damper device. Such an arrangement enables spaces between the pinion gears to be used effectively, increases spaces for the first spring, the second spring and the inner spring and improves a vibration damping performance of a damper device.

摘要： A damper device includes first inner springs configured to transmit a torque between a drive member and an intermediate member, second inner springs configured to transmit a torque between the intermediate member and a driven member, and a rotary inertia mass damper including a sun gear serving as a mass body rotating with relative rotation of the drive member to the driven member. The rotary inertia mass damper is provided in parallel to a torque transmission path including the intermediate member, the first inner springs and the second inner springs. A damping ratio ζ of the intermediate member determined based on a moment of inertia J2 of the intermediate member and rigidities k1 and k2 of the first and the second inner springs and is less than a value.

摘要： An intermediate member includes first and second intermediate members. The first and the second intermediate members are provided with a spring supporting portion that extends along springs and supports the springs from an outer side. An expansion and contraction of the springs enables the intermediate member to be movable in a circumferential direction. Accordingly, sliding distances caused by the expansion and contraction of the first and the second springs become shorter, compared with a configuration where the first and the second spring are supported by the driven member or drive member from the outer side, thereby decreasing an energy loss (hysteresis) caused by the sliding. As a result, a vibration damping performance of the damper device can be improved.

摘要： A vibration damping device including a support member rotabable about the center of rotation of a rotary element; a restoring force generation member coupled to the support member; an inertial mass body coupled to the support member via the restoring force generation member; and a guided portion and a guide portion provided alternately on one of the restoring force generation member or the inertial mass body. The guide portion guides the guided portion so the restoring force generation member swings along the radial direction of the center of rotation and the inertial mass body swings about the center of rotation when the support member is rotated. A component of a centrifugal force acting on the restoring force generation member is transferred from the guided portion to the guide portion. The restoring force generation member includes two mass bodies facing each other and disposed on sides of the inertial mass body.

摘要： A vibration damping device includes a supporting member rotatable about a rotation center of a rotating element, a restoring-force generating member coupled to the supporting member, and an inertial mass body coupled to the supporting member via the restoring-force generating member. The restoring-force generating member includes two guidable portions disposed with a clearance therebetween in a circumferential direction of the rotating element, and a torque transmission portion between the two guidable portions to transmit torque to and from the supporting member. The inertial mass body includes multiple guide portions for guiding corresponding guidable portions. When the supporting member rotates, the guidable portions transmit a component force of centrifugal force acting on the restoring-force generating member to the inertial mass body via the guide portions so the restoring-force generating member swings relative to the rotation center along a radial direction so that the inertial mass body swings about the rotation center.
