Patent number: 5641045Abstract: Balls to be moved radially outward by a centrifugal force are held in a clutch hub, and projections extending around the outer circumferences of the balls are united with a synchronizer ring. Those portions of the projections, which radially confront the balls, are formed with slopes for establishing an axial force to push the synchronizer ring away from the spline piece on the basis of the centrifugal force of the balls. Thus, the axial force for disengaging the synchronizer ring from a rotating member to be synchronized can be increased to prevent the chatter at a low number of revolution and to effectively eliminate the drag torque at a high number of revolution.Type: GrantFiled: June 1, 1995Date of Patent: June 24, 1997Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shinji Ogawa, Masayuki Kii, Tomoyuki Kanou

Patent number: 5499703Abstract: An idler mass member is provided inside or outside a torque transmittance path including a clutch for connecting and disconnecting an engine side and a transmission side having a synchromesh. The idler mass member is detached from a power train when the clutch is disengaged and is brought into contact or engagement with a driven side of the power train when or before the clutch is moved to be engaged. Due to the idler mass member, a peak torque generated in the driven side at a rushed start of an automobile is decreased.Type: GrantFiled: October 22, 1993Date of Patent: March 19, 1996Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masayuki Kii, Hiroaki Nimura, Mitsuhiro Umeyama
