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.

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.

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.

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.

A centrifugal-pendulum vibration absorbing device comprising having a support member coupled to a rotary element that is rotated by power from a drive device, and a mass body coupled to the support member so as to swing about a pendulum fulcrum and rotate about a center of gravity. 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 rotational angle of the mass body about the pendulum fulcrum and a rotational angle of the mass body about the center of gravity.

A four-bar linkage vibration absorbing device includes: crank members each coupled to a driven member of a damper device via a coupling shaft and each capable of swinging about the coupling shaft when the driven member is rotated; and a mass body that is coupled to the driven member via the crank members and that swings about the rotation center RC together with the crank members when the driven member is rotated. The driven member is coupled to a turbine runner of a hydraulic transmission device so as to rotate with the turbine runner.

摘要:
A cushioning member between plate bodies of a mass body and at end portions, in the circumferential direction, so as not to rotate relative to the plate bodies. The peripheral edges, on both sides in the width direction, of the outer peripheral surfaces of the cushioning member's first and second side portions abutting against a support member, along with swing of the mass body, are chamfered, reducing the possibility that the cushioning member enters in a clearance between the side surfaces of the support member and the plate bodies when the cushioning members' first side portion and the support member abut, or when the cushioning member's second side portion and the support member abut, along with swing of the mass body, suppressing damage to the cushioning member.
