Publication number: 20080173485Abstract: A control device for hybrid vehicle is provided with property alter means 88 that is operative based on whether or not an EV running mode is set and alters a given property used for determining demanded output torque TOUTt of a transmission mechanism 10 by referring to an accelerator opening Acc. This suppresses occurrence of engine startup to meet a requirement for the EV running mode to be initiated. The property alter means 88 alters the given property such that during an EV running mode turn-on state, demanded output torque TOUTt determined based on the accelerator opening Acc has a lower value than that set for an EV running mode turn-off state. That is, this causes a drop in sensitivity of demanded output torque TOUTt determined based on the accelerator opening Acc. Thus, the occurrence of engine startup induced upon depressive operation of an accelerator pedal during the EV running mode is suppressed.Type: ApplicationFiled: January 15, 2008Publication date: July 24, 2008Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kenta Kumazaki, Tooru Matsubara, Atsushi Tabata

Publication number: 20080173510Abstract: Disclosed is a torque converter, which comprises at least two thrust bearings disposed on respective axially-opposite sides of a radially-inward portion of a stator. The stator includes a non-rotatable member, a rotatable member and a one-way clutch. The rotatable member has a cylindrical portion having an inner peripheral surface interlocked with the one-way clutch, and an extension portion which extends from an approximately axially-central region of the cylindrical portion in a radially-outward direction relative to the cylindrical portion, and has an axial thickness less than that of the cylindrical portion. The thrust bearings are disposed to clamp the extension portion from respective axially-opposite sides of the extension portion at respective positions located radially outwardly relative to the cylindrical portion, so as to facilitate reduction in axial dimension of the torque converter.Type: ApplicationFiled: August 30, 2007Publication date: July 24, 2008Applicant: MAZDA MOTOR CORPORATIONInventor: Tokimori Saka

Publication number: 20080173511Abstract: A supporting structure for a one-way clutch supports the one-way clutch arranged between a stator of a torque converter for transmitting a torque from an engine to a transmission side via a fluid and a shaft at the transmission side. The supporting structure includes a first protrusion and a first contact plate. The first protrusion is provided at an inner periphery of the stator and protruding towards an inner-peripheral side of the stator. The first contact plate is fitted between the one-way clutch and the first protrusion of the stator and supports the one-way clutch while restraining an axial movement of the one-way clutch.Type: ApplicationFiled: January 22, 2008Publication date: July 24, 2008Applicant: EXEDY CorporationInventors: Kazuhito MAEDA, Ryousuke Iida
