Abstract: A multi speed transmission in planetary design for a vehicle, the transmission having a housing, a first shaft (1) as a drive (AN), a second shaft (2) as an output (Ab) axially parallel to the drive, three planetary gear sets (RS1, RS2, RS3), additional shafts (3-10), and six shifting elements (K1, K2, K3, K4, K5, B1) actuatable to realize several gear ratios. The transmission further includes machine elements (ST1, ST2) that transfer torque between the drive (AN) and the output (Ab). The first shaft (1) is connected to the planetary gear carrier (PT1) of the first planetary gear set (RS1) and is connectable at least to the sun gear (SR2) of the second planetary gear set (RS2) and to the ring gear (HR3) of the third planetary gear set (RS3). Additionally, the second shaft (2) is connected to the first machine element (ST1) and to the second machine element (ST2).

Abstract: An automatic transmission has eight rotatable shafts, four planetary gear sets and seven shift elements for shifting several forward gears and one reverse gear. A first element of the second planetary gear set forms the first shaft designed as the drive shaft of the transmission. A second element of the third planetary gear set forms the second shaft designed as the output shaft of the transmission. A second element of the first planetary gear set forms the third shaft. A first element of the first planetary gear set forms the fourth shaft. A third element of third planetary gear set forms the fifth shaft. As the sixth shaft, a third element of the first planetary gear set, a second element of the second planetary gear set and a first element of the third planetary gear set are constantly connected. A third element of the second planetary gear set forms the seventh shaft. A first brake is arranged in the power flow between the third shaft and the housing. A second brake is arranged in the power flow between the fourth shaft and the housing, a third brake is arranged in the power flow between the fifth shaft) and the housing. A first clutch (C1) is arranged in the power flow between the first and the seventh shafts. A second clutch is arranged in the power flow between the first and third shafts.

Abstract: A system for locking and releasing a shifting position of a shifting element that is hydraulically actuatable by an actuating pressure is provided. The shifting element is arranged coaxially with a transmission shaft. The system includes a stop valve. The stop valve is subjectable to a control pressure that is separate from the actuating pressure of the shifting element. The stop valve is arranged radially inside the shifting element in the transmission housing.
