摘要： A torsional vibration damper that damps torsional vibration effectively in a low-speed range. In the torsional vibration damper, a spring holder is formed by apertures of an input element and an output element, and an elastic member is held in the spring holder. A first moveable range of a planetary element extending from an initial position in a drive direction is wider than a second movable range of the planetary element extending from the initial position in a counter direction.

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 damper device 10 includes a dynamic damper 30 that has third springs SP3 coupled to an intermediate member 12 and that also has, as a mass body coupled to the third springs SP3, a turbine runner 5, a coupling member 31, etc. The third springs SP3 of the dynamic damper 30 are disposed so as to overlap both in the axial and radial directions of the damper device 10 second springs SP2 that are disposed inward of the first springs SP1 to transfer torque between a drive member 11 and a driven member 15. A plane PL including the axes of the third springs SP3 and perpendicular to the axis of the damper device 10 is included in the range of the thickness of spring contact portions 31c of the coupling member 31 in the axial direction of the damper device 10.

摘要： A centrifugal-pendulum vibration absorbing device disposed within a liquid chamber that stores a liquid, the centrifugal-pendulum vibration absorbing device having a support member coupled to a rotary element that is rotated by power from a drive device; and a mass body supported by the support member so as to be swingable. An order of vibration of the mass body is determined on the basis of an order of vibration to be damped generated by the drive device in consideration of at least a force caused by a centrifugal liquid pressure generated within the liquid chamber along with rotation of the drive device to act on the mass body.

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.

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： A torsional vibration damper whose vibration damping performance will not be reduced in a high speed range. In the torsional vibration damper, a planetary gear is oscillated within a first oscillating range when a torsional torque is smaller than a reference torque, and within a second oscillating range when the torsional torque is greater than the reference torque. Each backlash between the pinion gear and at least one of a sun gear and a ring gear within the second oscillating range is individually wider than each backlash between the pinion gear and the sun gear and each backlash between the pinion gear and the ring gear within the first oscillating range.
