Patent number: 9494202Abstract: An annular groove is provided in a driving-side rotor of a clutch. Guide grooves are provided on a driven-side rotor of the clutch. By moving the driving-side rotor relative to the driven-side rotor, balls are moved that are accommodated in the spaces provided by the sections where the guide grooves and the annular groove face each other. Moving the balls toward the sections where the gap between the driving-side rotor and the driven-side rotor is narrow causes the balls to engage with the driving-side rotor and the driven-side rotor to achieve an engaged state. A disengaged state, in which engagement is cancelled, is achieved by moving the balls to the sections where the gap is wide.Type: GrantFiled: July 18, 2014Date of Patent: November 15, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hirotaka Sunada, Shintaro Nakano, Daisuke Kobayashi, Akifumi Oosugi

Patent number: 8955476Abstract: A variable valve operating apparatus for an internal combustion engine is provided which includes a helical wall part provided in a guide rail for changing valve opening characteristics of a valve and a projection part, and can secure a contact area between the two when the two are engaged, thus successfully reducing the contact pressure generated between the two. The placement of the projection part with respect to the helical wall part is determined such that the central axis line of the projection part and the central axis line of a camshaft perpendicularly intersect with each other in a state in which the projection part is protruded toward the guide rail by an actuator.Type: GrantFiled: November 25, 2009Date of Patent: February 17, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hirotaka Sunada, Motohiro Tsuzuki, Woongseon Ryu, Akihiko Kawata

Patent number: 8925504Abstract: Provided is a variable valve operating apparatus for an internal combustion engine, which can switch, based on an actuation of a single actuator, operating characteristics of valves for a plurality of cylinders collectively and smoothly using a rigid member, while suppressing an increase in wear of a guide rail and reducing the number of delay mechanisms. A changeover mechanism to switch operating characteristics of valves for each cylinder of first and second cylinder groups is provided. The changeover mechanism includes link shafts as a rigid member which is displaced when being engaged with a helical guide rail as a result of the actuation of an electromagnetic solenoid. The changeover mechanism includes a delay mechanism, which delays the displacement of the second link shaft in a cylinder in which the valves are lifting when the electromagnetic solenoid is actuated, at some point in the link shafts between the first cylinder group and the second cylinder group.Type: GrantFiled: June 7, 2010Date of Patent: January 6, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Motohiro Tsuzuki, Shinobu Shimasaki, Akio Kidooka, Hirotaka Sunada
