  • Centrifugal pendulum-type vibration absorbing device and designing method for the same
    Patent number: 10208832
    Abstract: A centrifugal pendulum-type vibration absorbing device that includes a support that rotates together with any one of the rotary elements of the damper; and a mass that is supported by the support so as to oscillate freely, wherein the centrifugal pendulum-type vibration absorbing device is designed to have an effective order that is greater by at least a correction amount associated with the hysteresis of the damper than an order of vibration that is generated in the driving device to be damped.
    Type: Grant
    Filed: February 24, 2015
    Date of Patent: February 19, 2019
    Assignee: AISIN AW CO., LTD.
    Inventors: Hiroki Tsuji, Akihiro Nagae, Yoichi Oi, Kazuto Maruyama, Tomoki Inagaki, Hideaki Miyakoshi
  • Starting device
    Patent number: 10018261
    Abstract: When “It” is defined as the moment of inertia of all elements included in a torque transmission path from a front cover 3 to a damper hub 7, “Im” is defined as the moment of inertia of a first intermediate member 12 coupled to a vibration absorption spring Spd of a dynamic damper 20, “Idd” is defined as the moment of inertia of a mass body of the dynamic damper 20, “A=Im/It”, “B=Idd/Im”, and “Netag” is defined as a rotation speed of an engine corresponding to a frequency of vibration to be damped by the dynamic damper, the starting device is configured so as to satisfy 0.04?A?0.10, 0.90?B?2.60 and 900 rpm?Netag?1400 rpm.
