Patent number: 10072728Abstract: A cushioning member between plate bodies of a mass body and at end portions, in the circumferential direction, so as not to rotate relative to the plate bodies. The peripheral edges, on both sides in the width direction, of the outer peripheral surfaces of the cushioning member's first and second side portions abutting against a support member, along with swing of the mass body, are chamfered, reducing the possibility that the cushioning member enters in a clearance between the side surfaces of the support member and the plate bodies when the cushioning members' first side portion and the support member abut, or when the cushioning member's second side portion and the support member abut, along with swing of the mass body, suppressing damage to the cushioning member.Type: GrantFiled: August 6, 2014Date of Patent: September 11, 2018Assignee: AISIN AW CO., LTD.Inventors: Yoshihiro Takikawa, Yoichi Oi, Takayuki Miyaoka, Yuichiro Hirai

Patent number: 9915318Abstract: 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.Type: GrantFiled: August 6, 2015Date of Patent: March 13, 2018Assignees: AISIN AW CO., LTD., AISIN AW INDUSTRIES CO., LTDInventors: Yoshihiro Takikawa, Yoichi Oi, Hiroki Nagai, Takayuki Miyaoka, Yuichiro Hirai, Takuya Yoshikawa, Tomonori Kinoshita, Aki Ogawa

Patent number: 9791019Abstract: An intermediate member of a damper device includes a plate portion that has spring abutment portions that abut against inner springs. Spring abutment portions of a coupling member of a dynamic damper extend from a fixed portion via a bent portion to be disposed in opening portions of the plate portion, and abut against end portions of third springs disposed in the opening portions such that the third springs are arranged side by side with the inner springs in the circumferential direction. The plate portion and the spring abutment portions at least partially overlap each other in the thickness direction. The axes of the inner springs and the third springs are included within the range of overlap between the plate portion and the spring abutment portions in the thickness direction.Type: GrantFiled: October 16, 2014Date of Patent: October 17, 2017Assignee: AISIN AW CO., LTD.Inventors: Yoshihiro Takikawa, Yoichi Oi, Takayuki Miyaoka, Yuichiro Hirai, Makoto Yamaguchi, Takuya Yoshikawa, Masahiro Hata

Publication number: 20160195159Abstract: A mass body that includes two weights that face each other via a support member is provided. Each of the two weights is formed with a recessed portion that is recessed from an outside surface toward an inside surface. An additional weight formed of a material that is higher in specific gravity than the weight is attached to the recessed portion. Consequently, the weight of the mass body can be increased without increasing the radial length or the thickness of the mass body (weights). As a result, the vibration damping effect can be improved while suppressing an increase in size of the device.Type: ApplicationFiled: August 6, 2014Publication date: July 7, 2016Applicant: AISIN AW CO., LTD.Inventors: Yoshihiro TAKIKAWA, Yoichi OI, Takayuki MIYAOKA, Yuichiro HIRAI
