Patent number: 9435397Abstract: The present invention relates to a torsional vibration damping device in which a contact site with an inertial mass can be lubricated effectively while reducing resistance of the inertial mass to oscillate. The vibration damping device includes a rotary member that is rotated by a torque, and an inertial mass that is oscillated by torque pulses. The inertial mass is held in a chamber formed on the rotary member liquid-tightly together with lubrication oil while being allowed to be oscillated by torque pulses in the rotational direction of the rotary member. An amount of the lubrication oil is adjusted in a manner such that the inertial mass will not be brought into contact with an oil film of the lubrication oil centrifugally adhering to a radially outer section of an inner face of the chamber.Type: GrantFiled: November 1, 2012Date of Patent: September 6, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shingo Aijima, Yu Miyahara, Fusahiro Tsukano, Hiroyuki Amano, Hirotsugu Yoshino, Tadashi Sekiguchi, Syuhei Horita, Naoyuki Kishimoto, Yoshihiro Miyamachi

Publication number: 20150005078Abstract: A vibration damping device in which vibration damping performance of a damper having a chamber holding a rolling member is improved. The vibration damping device is adapted to damp vibrations resulting from a pulsation of torque applied to a rotary member by an oscillating motion of a rolling member connected with the rotary member while being allowed to rotate relatively therewith. The vibration damping device is provided with a casing member enclosing the rolling member, and a sealing member that connects the casing member with the rotary member in a manner such that the rotary member is allowed to rotate relatively with the casing member, while preventing oil from entering into an inner space of the casing member where the rolling member is held to oscillate.Type: ApplicationFiled: April 27, 2012Publication date: January 1, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tadashi Sekiguchi, Hiroyuki Amano
