摘要:
An automatic planetary transmission comprising a drive input shaft (AN), a drive output shaft (AB), first, second, third and fourth planetary gearsets (RS1,RS2,RS3, RS4) and six shifting elements (A, B, C, D, E, F). By the selectively engagement, in each case, three of the six shifting elements (A, B, C, D, E, F), ten forward gears and up to two reverse gears can be engaged without any range shifts.
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.
摘要:
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).
摘要:
An oil-guiding shaft (1, 8) with an inner shaft space (35) coaxial with or axis-parallel to the longitudinal axis (34) of the shaft and with mechanisms arranged in the inner shaft space (35) for dividing the inner shaft space into at least two oil-guiding ducts separated from one another. To enable a plurality of oil-guiding ducts to be produced in a comparatively thin shaft (1, 8), the invention proposes that the ducts (3, 4, 5, 9, 10, 11, 12) are formed as ducts (3, 4, 5, 9, 10, 11, 12) open along their length on the inside wall (2) of the shaft (1) and separated and sealed from one another by a tube (6, 13) inserted into the inner shaft space (35).

摘要:
A rotationally fixed connection of first and second components (2, 4) of a transmission (1) for torque transfer. The fixed connection is produced by the combination of two different types of connection elements (6, 7, 8, 9), such that the connection elements (6, 8) of a first type ensures the mutual centering of the first and the second components (2, 4) to be connected and torque transfer, while the connection elements (7, 9) of a second type enable the first and the second components (2, 4) to be axially fixed and transfer axial operating forces.
摘要:
A planetary gearset (2) consisting of a planetary gear carrier (4) that holds planetary gears (5) with a first and a second carrier plate (4b, 7), each having respective bores (4d, 7a) to receive planetary gear bolts (6) that can be fixed axially. It is proposed that the planetary gear carrier is connected in a rotationally fixed manner by the second carrier plate to a torque-transmitting component (8) of an adjacent shift element (3).

A transmission device (1) having at least one planetary gearset (2) and at least one frictional shift element (3) by which a ring gear (4), of the planetary gearset (2), can be connected to a component (5) that is fixed to a transmission housing. The ring gear (4) of the planetary gearset (2) is at least partially radially arranged within an inner disk carrier (6) of the shift element (3). The ring gear (4) and the inner disk carrier (6) are supported on a main transmission shaft (7) by a common carrier element (8). The ring gear (4) and the inner disk carrier (6) are radially separated from one another at least over a certain area.
