Powershift transmission having a drive shaft, a first gearwheel and a second gearwheel, which are each rotationally arranged on the drive shaft, and a layshaft/output shaft. In addition, a third gearwheel is provided which is arranged on the layshaft/output shaft, and which meshes with the first gearwheel, and a fourth gearwheel which is rotationally arranged on the layshaft/output shaft and which meshes with the second gearwheel. Furthermore, a first positively locking element is provided which is arranged on the drive shaft in a rotationally fixed and displaceable fashion and which is decoupled from the first gearwheel in a first shifted position, and which is rotationally coupled to the first gearwheel in a second shifted position. In the second shifted position, the first positively locking element is rotationally coupled to the first gearwheel in a first rotational direction of the first gearwheel, and in a second rotational direction, opposed to the first rotational direction, of the first gearwheel said first positively locking element is decoupled from the first gearwheel by means of a freewheel. |
