UNIVERSAL JOINT SHAFT

A universal joint shaft can be provided for transmitting torque between a power take-off shaft of a driving agricultural machine and a drive journal of an agricultural implement to be driven. The universal joint shaft comprises a first joint with a first inner joint member and a first outer joint member, which are pivotably and torque-transmittingly connected to each other, a second joint, with a second inner joint member and a second outer joint member, which are pivotably and torque-transmittingly connected to each other, a connecting shaft, via which the first inner joint member and the second inner joint member are connected to each other in a rotationally fixed manner, and a connecting hub which is rigidly connected to the first outer joint member and has connecting means for connecting the connecting hub to a shaft in a rotationally fixed manner, a housing in which the connecting hub is accommodated and rotatably mounted, and a generator accommodated in the housing, said generator has a stator rigidly connected to the housing and arranged coaxially to the connecting hub, and said generator further has a rotor rotatably mounted relative to the housing, wherein the rotor is drivingly connected to the connecting hub via a transmission.
