The carrier of the second gearset (P2) couples the input which is connectable by clutch (15) to the fifth shaft (5). The fifth shaft (5) respectively couples the sun and ring gears of the fourth and third gearsets (P4, P3) and is connectable to a seventh shaft (7) by clutch (57). The seventh shaft (7) respectively couples the sun and ring gears of the third and the second gearsets (P3, P2). Output shaft couples the carrier of the fourth gearset (P4) and, via clutch (28), the eight shaft (8) which is connected to the carrier of the third gearset (P3), and clutch (18) couples the eight shaft (8) to the input.

摘要:
A planetary transmission with at least one planetary gearset including planetary gears supported on a planetary gear carrier. The planetary carrier has inner teeth, which engage outer teeth of a shaft to form a lock tooth array. To secure the planetary carrier axially on the shaft, the planetary carrier is placed with one axial end against a stop on the shaft and the opposite axial end is fixed axially with a circlip fit into a circlip groove in the shaft. At least one axially adjacent component is supported against the planetary carrier such that an axial bearing is arranged radially and axially adjacent to the circlip and includes a roller group guided in a cage and a first check-disk A second check-disk is arranged radially opposite and at a distance from the circlip in such manner that when assembled, the circlip cannot escape from the circlip groove in the shaft.

A multi-stage automatic transmission possesses an input drive shaft (AN), an output drive shaft (AB), three single planetary gear sets (RS1, RS2, RS3) as well as five shifting elements (A to E), via the pairwise selective closure of which, an entry speed of rotation of the input drive shaft (AN) can be transmitted to the output drive shaft (AB) without group shifting. A sun gear (SO3) of the third planetary gear set (RS3) can be set motionless by the first shifting element (A) on the transmission housing (GG). The input drive shaft (AN) is bound to a sun gear (SO2) of the second planetary gear set (RS2) and via the second shifting element (B) can be connected with a sun gear (SO1) of the first planetary gear set (RS1) and via of the fifth shifting element (E) with a spider (ST1) of the first planetary gear set (RS1).

A transmission with a planetary gearset including planetary gears supported on a carrier, with a disk clutch or brake including a disk carrier which, via an integral cylindrical portion, is fixed to a shaft that supports the disk carrier, such that the carrier rotates on the cylindrical portion and the carrier is supported by a first axial bearing on the disk carrier and a second axial bearing on a sun gear, which engages the planetary gears, and with an oil supply for lubricating and/or cooling bearings, disk clutch and/or brake components. The first axial bearing includes rollers guided in a cage and first check-disk adjacent the carrier and a second check-disk rollers. The first check-disk flanged disk with a section for rollers of the first axial bearing and with a cylindrical section offset from the rolling section.
