Patent number: 7530437Abstract: A transmission synchronizer that effectively lowers the peak value of the operation load during synchronization is provided. The transmission synchronizer is equipped with a coupling sleeve, synchro hub, balk ring and clutch gear. A synchronizing support force generating mechanism, during a shift when relative rotation is generated between the synchro hub and the balk ring by a minute synchronizing torque generated between balk ring cone surface and clutch gear cone surface, converts a circumferential force induced by that relative rotation to an axially applied synchronizing support force, with which the balk ring is pressed against the clutch gear. A relative rotation regulating structure is located between the balk ring and the synchro hub, and when in neutral, it regulates the amount of relative rotation between the balk ring and the synchro hub so that the synchronizing support force is not generated.Type: GrantFiled: October 27, 2005Date of Patent: May 12, 2009Assignee: Nissan Motor Co. Ltd.Inventors: Akihiro Miyamoto, Masashi Yoshino

Publication number: 20090031837Abstract: In a synchronizing device of a transmission, in which when a coupling sleeve is slidingly moved on a synchronizer hub during gear shift operation, the coupling sleeve is engaged with a balk ring by a rotating synchronizing action, and then the coupling sleeve is further slidingly moved until the coupling sleeve is engaged with a clutch gear to complete the gear shift operation, the synchronizing device includes a guide rail mechanism, provided between the coupling sleeve and the synchronizer hub, to suppress a fall of the coupling sleeve during the sliding movement of the coupling sleeve. The guide rail mechanism is set in a sliding-movement range from a neutral position of the coupling sleeve to at least a position where a coupling-sleeve chamfer and a balk-ring chamfer abut with each other.Type: ApplicationFiled: January 10, 2007Publication date: February 5, 2009Inventor: Masashi Yoshino

Publication number: 20080245169Abstract: To provide a transmission synchronizer that effectively lower the peak value of the operation load during synchronisation. A transmission synchronizer equipped with a coupling sleeve 1, synchro hub 5, balk ring 4, and clutch gear 3, comprising: a synchronizing support force generating mechanism that during a shift when relative rotation is generated between said synchro hub 5 and said balk ring 4 by a minute synchronizing torque generated between balk ring cone surface 4a and clutch gear cone surface 3a, converts a circumferential force induced by said relative rotation to an axially applied synchronizing support force, with which said balk ring 4 is pressed against said clutch gear 3; and a relative rotation regulating structure that is located between said balk ring 4 and said synchro hub 5, and when in neutral, regulates the amount of relative rotation between said balk ring 4 and said synchro hub 5 so that said synchronizing support force is not generated.Type: ApplicationFiled: October 27, 2005Publication date: October 9, 2008Inventors: Akihiro Miyamoto, Masashi Yoshino

Patent number: 7163093Abstract: A synchronizer for a transmission including: a synchronizer hub; a synchronizer sleeve slidable thereon to engage with a clutch gear, which is provided with sleeve spline teeth having sleeve chamfers; and a synchro ring having a plurality of pairs of synchro ring spline teeth each having a synchro ring chamfer for receiving one of the sleeve chamfers. The synchro ring chamfer has a leading edge offset from the center of each synchro ring spline tooth, so that a distance between the leading edges becomes greater than a distance between the centers of the synchro ring spline teeth in each of the pairs of the synchro ring spline teeth. Moreover, the sleeve spline teeth are provided on the synchronizer sleeve only in angular positions between the synchro ring spline teeth of each of the pairs.Type: GrantFiled: February 23, 2005Date of Patent: January 16, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Akihiro Miyamoto, Masashi Yoshino
