1. A transmission for vehicles, comprising:
a first planetary gear set, a second planetary gear set, a third planetary gear set, and a fourth planetary gear set; and a plurality of friction members, wherein the plurality of friction members include a brake, a first clutch, a second clutch, a third clutch, a fourth clutch and a fifth clutch, wherein the first planetary gear set includes:
a first rotary element connected to an input shaft;a second rotary element operating as a selectively-fixed element; anda third rotary element continuously connected with a second rotary element of the second planetary gear set and selectively connected with a third rotary element of the third planetary gear set, wherein the second planetary gear set includes:
a first rotary element selectively connected with a second rotary element of the third planetary gear set and selectively connected with the third rotary element of the third planetary gear set;the second rotary element of the second planetary gear set, wherein the second rotary element of the second planetary gear set is selectively connected with a third rotary element of the fourth planetary gear set; anda third rotary element operating as a fixed element, wherein the third planetary gear set includes:
a first rotary element continuously connected with a second rotary element of the fourth planetary gear set; andthe second rotary element of the third planetary gear set, wherein the second rotary element of the third planetary gear set is selectively connected to the input shaft, wherein the fourth planetary gear set includes:
a first rotary element connected to the input shaft; andthe second rotary element of the fourth planetary gear set, wherein the second rotary element of the fourth planetary gear set is connected to an output shaft, wherein each of the friction members is connected to at least one or more of the rotary elements of the planetary gear sets and control rotation of the rotary elements, wherein the first rotary element of the first planetary gear set is a first sun gear, the second rotary element of the first planetary gear set is a first carrier, and the third rotary element of the first planetary gear set is a first ring gear, wherein the first rotary element of the second planetary gear set is a second sun gear, the second rotary element of the second planetary gear set is a second carrier, and the third rotary element of the second planetary gear set is a second ring gear, wherein the first rotary element of the third planetary gear set is a third sun gear, the second rotary element of the third planetary gear set is a third carrier, and the third rotary element of the third planetary gear set is a third ring gear, and wherein the first rotary element of the fourth planetary gear set is a fourth sun gear, the second rotary element of the fourth planetary gear set is a fourth carrier, and the third rotary element of the fourth planetary gear set is a fourth ring gear. |
