Abstract

A planetary transmission includes a planetary gear set (1), another planetary gear set (2), a fluid line (3) through which fluid is flowable to the planetary gear set (1) and to the other planetary gear set (2), and a fluid collecting device (4) which is in fluid communication with the fluid line (3). The fluid collecting device (4) is connected in a rotationally fixed manner to the planetary gear set (1). The fluid collecting device (4) is configured for dividing the fluid from the fluid line (3) which has flowed into the fluid collecting device (4) into a fluid part which is flowable to the planetary gear set (1) and another fluid part which is flowable to the other planetary gear set (2).
