Publication number: 20240132147Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.Type: ApplicationFiled: October 11, 2023Publication date: April 25, 2024Applicants: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Yuuta KAJISAWA, Yuji FUJITA, Yugo NAGASHIMA, Kazuma HASEGAWA, Takashi KOUDAI, Kaishi MONOBE, Kenichi ABE, Masaharu YAMASHITA, Shintaro TAKAYAMA, Kazuaki IIDA, Yasushi HORA, Yosuke YAMASHITA, Hiroki TOMIZAWA, Nobuyori NAKAJIMA, Hayaki TANABE, Toyohiro HAYASHI, Takeshi IWANA

Publication number: 20240035401Abstract: A lower link (6) is provided with an oil hole (30) in a crank pin bearing portion (11) in order to supply a jet of oil to a connecting portion between an upper pin (4) and an upper link (3). Oil hole (30) is composed of a first oil hole (31) linearly extending from the inner peripheral surface of crank pin bearing portion (11) outwardly in the radial direction, and a second oil hole (32) linearly extending from the outer surface of lower link (6) so as to intersect a distal end portion of first oil hole (31). An inclination angle (?) of first oil hole (31) with a divided surface (14) set as a reference becomes relatively small, and hence the position of an oil inlet (31b) involving a problem of stress concentration becomes closer to divided surface (14) exhibiting a relatively low stress. Consequently, the stress concentration at oil inlet (31b) is alleviated.Type: ApplicationFiled: September 15, 2020Publication date: February 1, 2024Inventors: Hiroki ICHIHARA, Tomoya TOJO, Kensuke IKEHARA, Takashi TANABE, Katsutoshi NAKAMURA
