Patent number: 10487909Abstract: Six through holes are formed in pinion gear supporting portions of two input plate members working as a carrier that supports pinion gears of a rotary inertia mass damper. The two input plate members are opposed to each other in such a manner that the through holes are aligned with each other. The through holes support the pinion gear. The input plate members are coupled with each other by means of rivets passing through the through holes located on both sides of the through holes. This configuration ensures strength (rigidity) of the carrier, suppresses deformation of a planetary gear, and improves meshing accuracy of gears.Type: GrantFiled: June 27, 2016Date of Patent: November 26, 2019Assignees: AISIN AW INDUSTRIES CO., LTD, AISIN AW CO., LTD.Inventors: Takuya Yoshikawa, Aki Ogawa, Akiyoshi Kato, Ryosuke Otsuka, Kazuyoshi Ito, Masaki Wajima, Kazuhiro Itou

Publication number: 20180187743Abstract: An intermediate member includes first and second intermediate members. The first and the second intermediate members are provided with a spring supporting portion that extends along springs and supports the springs from an outer side. An expansion and contraction of the springs enables the intermediate member to be movable in a circumferential direction. Accordingly, sliding distances caused by the expansion and contraction of the first and the second springs become shorter, compared with a configuration where the first and the second spring are supported by the driven member or drive member from the outer side, thereby decreasing an energy loss (hysteresis) caused by the sliding. As a result, a vibration damping performance of the damper device can be improved.Type: ApplicationFiled: June 27, 2016Publication date: July 5, 2018Applicants: AISIN AW INDUSTRIES CO., LTD, AISIN AW CO., LTD.Inventors: Takuya YOSHIKAWA, Aki OGAWA, Akiyoshi KATO, Ryosuke OTSUKA, Kazuyoshi ITO, Masaki WAJIMA, Kazuhiro ITOU

Publication number: 20180149232Abstract: 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.Type: ApplicationFiled: June 27, 2016Publication date: May 31, 2018Applicants: AISIN AW INDUSTRIES CO., LTD, AISIN AW CO., LTD.Inventors: Takuya YOSHIKAWA, Aki OGAWA, Akiyoshi KATO, Ryosuke OTSUKA, Kazuyoshi ITO, Masaki WAJIMA, Kazuhiro ITOU
