摘要： A damper device includes rotating elements including an input element and an output element, first elastic bodies that each transmit torque between the input element and the output element, a plurality of second elastic bodies that act in parallel with the plurality of first elastic bodies when torque transmitted between the input element and the output element is greater than or equal to a predetermined value, and a rotary inertia mass damper. The rotary inertia mass damper includes a sun gear, a carrier that rotatably supports a plurality of pinion gears, and a ring gear that meshes with the plurality of pinion gears and that serves as a mass body. The plurality of second elastic bodies are located at a different position than the plurality of first elastic bodies in a radial direction of the rotating elements and are circumferentially aligned with the plurality of pinion gears.

摘要： A damper device including an input element and an output element; an elastic body transmitting torque between the input element and the output element; and a rotary inertia mass damper having a mass body. The rotary inertia mass damper includes a sun gear, a carrier rotatably supporting pinion gears, and a ring gear that meshes with the pinion gears and serving as the mass body. A pair of washers is located on both sides of each pinion gear axially. The ring gear includes an annulus gear having internal teeth meshing with the pinion gears and a weight body fixed to the annulus gear such that the weight body is in contact with a side surface of the annulus gear. An inner circumferential surface of the weight body is supported in a radial direction by a tip of the pinion gear or an outer circumferential surface of the washer.

摘要： A damper device includes a plurality of rotational elements, a plurality of elastic bodies, a rotary inertia mass damper and a housing that houses the plurality of rotational elements, the plurality of elastic bodies and the rotary inertia mass damper, the housing including a front cover. The rotary inertia mass damper is configured to include a planetary gear that includes a sun gear, a plurality of pinion gears, and a carrier that rotatably supports the plurality of pinion gears. The carrier is centered by either the sun gear or a member that rotates integrally with the sun gear by being radially supported by either the sun gear or the member that rotates integrally with the sun gear. In addition, the carrier is spline-engaged to the front cover when a lockup clutch is engaged.

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： 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 drive member of a damper device includes a first input plate member and a second input plate member that rotatably support a plurality of pinion gears of a planetary gear of a rotary inertia mass damper. A driven member includes an outer teeth gear portion that meshes with the pinion gear in an outer circumferential portion thereof and is disposed between the first and the second input plate members in an axial direction so as to work as a sun gear of the planetary gear. A stopper is configured to restrict the relative rotation between the drive member and the driven member and includes a contact portion arranged in the outer circumferential portion of the driven member so as to contact with the first input plate member.
