  • Patent number: 8801524
    Abstract: In a damper apparatus, power is transferred, in order, from a motor, to an input, to a first elastic body, to a first element, to a second elastic body, to a second element, to a third elastic body, and to an output. The first and second elastic bodies are disposed radially outward of the third elastic body, and adjacent to each other on a single circumference. The first element has an annular outer peripheral portion that surrounds the first and second elastic bodies, and a pair of contact portions that are formed on peripheral edges on respective sides of the outer peripheral portion to protrude from the peripheral edges radially inward and to face each other, and that are between and in contact with the first elastic body and the second elastic body.

  • Patent number: 8771088
    Abstract: A damper device including an input element to which power from a motor is transmitted; a first elastic body to which the power is transmitted from the input element; a first intermediate element to which the power is transmitted from the first elastic body; a second elastic body to which the power is transmitted from the first intermediate element; a second intermediate element to which the power is transmitted from the second elastic body, a third elastic body to which the power is transmitted from the second intermediate element; and an output element to which the power is transmitted from the third elastic body. The second elastic body is lighter than the first elastic body.

  • Publication number: 20140174869
    Abstract: 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.

  • Publication number: 20140174250
    Abstract: 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.
