| 20090266188 | CLUTCH CONTROL SYSTEM - A clutch control system includes a release fork rotatably supported by a release shaft via a support portion and including a press arm and a drive arm extending from the support portion, the press arm of which an end portion presses a release bearing provided at a clutch to bring the clutch to one of an engagement state and a disengagement state, a sector gear including sector teeth integrally formed at an end portion, the sector teeth being formed into an arc shape concentric to the release shaft, a worm wheel rotatably supported by a wheel shaft arranged in parallel with the release shaft, the worm wheel including teeth, a pinion gear integrally formed at the worm wheel and engaging with the sector teeth, and a worm driven to rotate by an electric motor and engaging with the teeth of the worm wheel to rotate the worm wheel. | 10-29-2009 |
| 20090266189 | CLUTCH CONTROL SYSTEM - A clutch control system includes a release fork including a press arm and a drive arm, the release fork operating a clutch to one of an engagement state and a disengagement state, a worm wheel rotatably supported by a wheel shaft and including teeth, a roller rotatably supported by a support pin of which one end is fixed to the worm wheel, the support pin extending in parallel with the wheel shaft while having a predetermined distance therefrom, and a worm driven to rotate by an electric motor and engaging with the teeth. When the worm wheel is driven by the motor, the roller presses a side portion of the drive arm to rotate the release fork, and a release bearing of the clutch is pressed by an end portion of the press arm to bring the clutch to one of the engagement state and the disengagement state. | 10-29-2009 |

| 20080207382 | AUTOMATIC TRANSMISSION - [Task] To provide an automatic transmission apparatus for forward 8-speed, which keeps a transmission gear ratio step in good balance. | 08-28-2008 |
| 20080207383 | AUTOMATIC TRANSMISSION - [Object] To provide an automatic transmission capable of providing a sufficient feeling of acceleration with a clear shift feeling at the time of shifting with acceleration by properly allocating step ratios between shift stages. | 08-28-2008 |
| 20080248913 | AUTOMATIC TRANSMISSION - An automatic transmission having a second ring gear of planetary gear mechanisms and is connected to an input shaft so as to be able to transmit power thereto, and a first sun gear and a second sun gear, and a first carrier that are connected to each other are in turn connected to a third control brake and a first control brake, respectively. A third sun gear and a fourth sun gear of the planetary gear mechanisms are connected to each other, and are in turn detachably connected to the input shaft | 10-09-2008 |
| 20100167866 | AUTOMATIC TRANSMISSION - An automatic transmission in which first to third clutches which can couple an input shaft to a first element of a first multiple planetary gear set and second and fourth elements of the second multiple planetary gear set, respectively, are arranged on a front side of the first multiple planetary gear set. Thus, it is possible to prevent a situation in which disengaging of the third clutch in the first speed causes the fourth element of the first multiple planetary gear set to rotate in reverse and generate a large relative rotation with the first element. | 07-01-2010 |
| 20100234164 | AUTOMATIC TRANSMISSION - An automatic transmission is provided that has appropriately spaced gear ratios for eight forward speeds to be capable of obtaining a shift feeling in all of the eight speeds, and that can be reduced in size and weight. | 09-16-2010 |
