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 |
