Embodiment Construction

[0047] figure 1 A transmission according to a first embodiment of the invention is shown.

[0048] exist figure 1 In , reference numeral 1 denotes a multi-stage transmission. The multi-stage transmission 1 includes six shift elements in the form of three clutches K1 , K2 , K3 and three brakes B1 , B2 , B3 . The drive side of the transmission can be coupled or connected to the output side by means of the clutches K1 , K2 , K3 for the transmission of forces and torques. To this end, the first clutch K1 , the second clutch K2 and the third clutch K3 are connected to the drive shaft ANW on the drive side. The first clutch K1 is also connected with the first shaft W1 such that the clutch, when operated, transmits force and torque from the drive shaft ANW to the first shaft W1. The same applies to the second clutch K2 and the third clutch K3. When the second clutch K2 is engaged, force is transmitted from the drive shaft ANW to the second shaft W2, and when the third clutch K3 ...
