Publication number: 20120217830Abstract: A vehicle drive device includes an input member coupled to an internal combustion engine; an output member coupled to a wheel; a rotating electrical machine; a fluid coupling; and a case containing at least the rotating electrical machine and the fluid coupling. The fluid coupling includes an input and an output that is paired with the input. The rotating electrical machine includes a rotor and a rotor support that extends radially inward from the rotor in an axial direction with respect to the coupling input, and supports the rotor via a support bearing. A power transmission member is formed by coupling at least the rotor support and the coupling input together so that at least the rotor support and the coupling input rotate together. A movement restricting mechanism restricts axial movement of the power transmission member toward the axial direction.Type: ApplicationFiled: November 19, 2010Publication date: August 30, 2012Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD.Inventors: Mikio Iwase, Tomohide Suzuki, Naoya Jinnai, Tatsuya Okishima, Toshihiko Kamiya

Publication number: 20110240430Abstract: A drive device for a vehicle configured between an internal combustion engine and a wheel. The drive device includes a rotary electric machine, and an engagement device connecting the drive device to the engine by a fluid coupling using hydraulic pressure. A case houses at least a portion of the drive device and includes a support wall extending radially, and a cylindrical projecting portion projecting from the support wall toward a side in an axial second direction that is in a direction opposite to the axial first direction. The engagement device includes an operating oil pressure chamber supplied with the hydraulic pressure. A rotor member of the rotary electric machine is radially supported by the cylindrical projecting portion in a rotatable state via a support bearing. The cylindrical projecting portion is formed with an operating oil supply passage supplying oil to the operating oil pressure chamber.Type: ApplicationFiled: November 18, 2010Publication date: October 6, 2011Applicants: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mikio Iwase, Tomohide Suzuki, Naoya Jinnai, Tatsuya Okishima, Toshihiko Kamiya

Publication number: 20110240431Abstract: A rotary electric drive device for a vehicle configured to couple a combustion engine to a wheel. The drive device includes an engagement device selectively drivingly connecting the input member with the rotary electric machine and a fluid coupling. The engagement device includes a differential pressure generating chamber that receives oil supply so as to apply hydraulic pressure to a side of the pressing member opposite to a side to which hydraulic pressure for operation is applied. A body portion housing chamber housing a body portion of the fluid coupling and the differential pressure generating chamber are structured as oil chambers independent of each other. The drive device includes a coupling supply oil passage supplying oil to the body portion housing chamber and a differential pressure supply oil passage supplying the oil to the differential pressure generating chamber.Type: ApplicationFiled: November 18, 2010Publication date: October 6, 2011Applicants: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mikio Iwase, Tomohide Suzuki, Naoya Jinnai, Tatsuya Okishima, Toshihiko Kamiya, Terufumi Miyazaki, Yukihiko Ideshio

Patent number: 7976608Abstract: In a solder paste which is a mixture of a flux and low melting point metal particles, low melting point metal fine particles manufactured by a conventional method or apparatus therefor include particles having widely varying particle diameters. Accordingly, the solder paste could not completely fill the minute holes in a mask for application to minute solder portions by printing, or mask removability was poor. According to the present invention, a mixture of a heat resistant continuous phase liquid and coarse metal particles in molten state is passed through a porous membrane to form the coarse low melting point metal particles into fine particles with a predetermined diameter. An apparatus according to the present invention comprise a porous membrane between a heating and dispersing mechanism and a cooling mechanism, and a pressure vessel connected to the heating and dispersing mechanism for applying a high pressure to the heating and dispersing mechanism.Type: GrantFiled: March 9, 2005Date of Patent: July 12, 2011Assignees: Senju Metal Industry Co., Ltd., Miyazaki PrefectureInventors: Kiyoshi Torigoe, Masataka Shimizu, Kenji Yamamoto, Mitsuhiro Mizozoe, Hoshiro Takahashi, Tomohide Suzuki, Motohiro Murase

Publication number: 20110121692Abstract: A vehicle drive device, having a case with a support wall that extends at least radially, and an axially protruding portion that is cylindrically shaped integrally with the support wall and protrudes axially from the support wall toward a rotating electrical machine. A rotor support member is supported radially and axially so as to be rotatable with respect to the axially protruding portion via a support bearing provided on an outer or inner peripheral surface of the axially protruding portion. The element to be supplied with the oil pressure is positioned on a side axially opposite to the support wall. The vehicle drive device includes a supply oil passage, which is provided inside the support wall and the axially protruding portion, and has an end face opening that is formed in an end face located in a protruding direction of the axially protruding portion.Type: ApplicationFiled: November 17, 2010Publication date: May 26, 2011Applicants: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mikio IWASE, Tomohide SUZUKI, Naoya JINNAI, Tatsuya OKISHIMA, Toshihiko KAMIYA

Publication number: 20040035000Abstract: An interior splined member is a hollow cylinder with an interior cylindrical surface defining a through hole. A major portion of the axial length of the interior cylindrical surface is splined to provide alternating axially extending ribs and troughs disposed between the ribs. A ring-shaped residual portion is an unsplined portion, i.e., a minor portion of the axial length of the interior cylindrical surface and is substantially circular with a diameter that is equal to or smaller than that of a circle on which the distal ends (tips) of the ribs lie. The trough portions are open at one end of the cylindrical member, while closed by the ring-shaped residual portion at the other end of the cylindrical member.Type: ApplicationFiled: June 16, 2003Publication date: February 26, 2004Inventors: Masaki Nakajima, Ariyoshi Terao, Tomohide Suzuki
