摘要
A 4-speed power train of automatic transmission is provided to easily and effectively perform the lubrication and cooling of the auto transmission by not using the overlapped hollow shaft structure. A 4-speed power train of automatic transmission comprises the first planetary gear set(PG-1), and the second planet gear set(PG-2). The first planetary gear set is connected variably to the input shaft(10). The first planetary gear set is arrested to the transmission case(30). The second planet gear set is connected variably to the input shaft. The second planet gear set is arrested to the transmission case. The first planetary gear set and the second planet gear set comprise the first actuating element, the second actuating element, the third actuating element and the fourth actuating element.
