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： 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 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 vibration damping device including: a support member rotating with a rotary element to which torque from an engine is transferred about the center of rotation of the rotary element; a restoring force generation member coupled to the support member and swingable with rotation of the support member; and an inertial mass body coupled to the support member via the restoring force generation member and swung about the center of rotation in conjunction with the restoring force generation member with rotation of the support member. The order of the vibration damping device is larger than the sum of the excitation order of the engine and an offset value determined in consideration of the effect of oil in the oil chamber. The reference order, which is a convergent value of the order of the vibration damping device, is higher than the excitation order.

摘要： 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.
