摘要： A damper device includes a first rotor, a second rotor, and an elastic coupling part. The elastic coupling part has a first torsional characteristic, a second torsional characteristic, and a third torsional characteristic. The first torsional characteristic is exerted with a first stiffness in a first actuation range of a torsion angle that ranges differently on the positive side and on the negative side. The second torsional characteristic is exerted with a second stiffness, which is greater in magnitude than the first stiffness, in a second actuation range of the torsion angle that ranges on the positive side of the first actuation range. The third torsional characteristic is exerted with a third stiffness, which is greater in magnitude than the first stiffness and different in magnitude from the second stiffness, in a third actuation range of the torsion angle that ranges on the negative side of the first actuation range.

摘要： A power transmission device is disposed between an engine and a transmission so as to be capable of attenuating fluctuations in torque. The device includes an input rotary part, an output rotary part, an elastic part, an inertia mass part and an engaging part. The torque is inputted to the input rotary part. The output rotary part is rotatable relatively to the input rotary part. The elastic part elastically couples the input rotary part and the output rotary part in a rotational direction. The inertia mass part is movable in the rotational direction. The engaging part is engaged with the elastic part and the inertia mass part. The engaging part actuates the elastic part by relative rotation between the input rotary part and the output rotary part and movement of the inertia mass part.

摘要： A damper device includes a torque limiter unit, a damper unit, and a positioning structure. The torque limiter unit includes a damper cover fixed to a surface of a flywheel on a first side of the flywheel in an axial direction. The damper unit is disposed such that an outer peripheral end thereof is located on a second side of an inner peripheral end of the damper cover in the axial direction. The damper unit transmits mechanical power together with the flywheel therebetween. The positioning structure radially sets the damper unit in place with respect to the torque limiter unit by making an outer peripheral surface of a core plate of a friction disc contactable with an inner surface of the damper cover of the torque limiter unit. The damper device is intended to inhibit displacement in radial position of a damper unit with respect to a torque limiter unit.

摘要： A damper device, disposed between an engine and a drive unit, includes an input rotor, an output rotor, an elastic coupling part, and a hysteresis torque generating mechanism. The hysteresis torque generating mechanism generates a hysteresis torque together with the input rotor or the output rotor therebetween. The damper device is in a neutral condition when a torque is not transmitted from both the engine and the drive unit, in a first torsional condition when the torque is transmitted from the engine, and in a second torsional condition when the torque is transmitted from the drive unit. The hysteresis torque generating mechanism is configured not to generate a hysteresis torque when the damper device is in the first torsional condition, and not to generate the hysteresis torque in a first range of torsion angle less than a first angle when the damper device is in the second torsional condition.

摘要： A damper device includes a first rotor, a second rotor, an elastic coupling part having first and second elastic members, and a hysteresis generating mechanism. The hysteresis generating mechanism includes a friction member, and generates a hysteresis torque. The friction member does not make frictional contact with the first and second rotors in a first torsion angular range where the torsion is caused between the first and second rotors by a first torsion angle from a neutral condition, makes frictional contact with the first or second rotor in a second torsion angular range exceeding the first torsion angle so as to generate the hysteresis torque, and does not make frictional contact with the first and second rotors in a predetermined torsion angular range within the second torsion angular range. In the neutral condition, the friction member is set in a neutral position by actuation of the elastic coupling part.

摘要： A torque limiter embedded damper device includes a torque limiter unit and a damper unit. The damper unit includes a first rotor, a second rotor, and a stopper mechanism. The second rotor includes a flange axially opposed to the first rotor. The stopper mechanism restricts an angle of relative rotation between the first rotor and the second rotor to a predetermined angular range. The stopper mechanism includes a cutout and a stop pin. The cutout is provided in the flange of the second rotor. The stop pin is fixed to the first rotor. The torque limiter unit includes a friction plate having an annular shape. The annular friction plate is fixed at an inner peripheral part thereof to an outer peripheral part of first rotor or the second rotor by a fixation member. The fixation member is fastened in a state of penetrating the cutout of the flange.

摘要： A damper device includes first and second rotors, a first pre-damper, and a first main elastic member. The second rotor includes a hub and a flange. The first pre-damper elastically couples the hub and the flange in a rotational direction, and is actuated in a first range of torsion angle between the first and second rotors. The first main elastic member elastically couples the first and second rotors in the rotational direction, and is actuated in a greater second range of torsion angle. The first pre-damper includes first and second subordinate elastic members. The first subordinate elastic member is compressed in a neutral state, and urges the flange to a first side in the rotational direction with respect to the hub. The second subordinate elastic member is compressed in the neutral state, and urges the flange to a second side in the rotational direction with respect to the hub.
