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 vibration damping apparatus that includes a plurality of rotational elements including an input to which a torque from an engine is transferred, and an output; a first torsional stiffness mechanism arranged between the input and the output and having a positive torsional stiffness; and a second torsional stiffness mechanism configured to act in parallel to the first torsional stiffness mechanism between the input and the output and having a negative torsional stiffness, wherein the negative torsional stiffness of the second torsional stiffness mechanism increases on a negative side as a rotation speed of the engine increases.

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: A center piece is coupled to a flange member to thereby form a second oil path between an intermediate wall portion of the center piece and the flange portion. A male screw portion is formed on an outer peripheral surface of a cylindrical portion of the center piece, and a nut member in which a female screw portion is formed on an inner peripheral surface is screwed to the male screw portion. Accordingly, the flange member is pressed onto the intermediate wall portion to thereby couple the center piece to the flange member. As a result, the center piece can be coupled to the flange member without causing backlash.
