Vehicle-side and accessory-side power take-off shaft connecting device and power take-off shaft connecting unit comprising the two power take-off shaft connecting devices

A power take off (PTO) connecting apparatus to couple a PTO drive of a vehicle with a PTO drive of accessory equipment, wherein a vehicle PTO connecting device with a releasable nonpositively connectable and couplable attachment PTO connecting device are present wherein mechanical coupling elements are provided on the vehicle and mechanical counter coupling elements are provided on the accessory equipment with the coupling elements of the vehicle configured to slide into the coupling elements of the accessory equipment and interlock,

• wherein the vehicle PTO connecting device and the attachment PTO connecting device are each secured axially to the vehicle or to the accessory equipment, or, respectively, the coupling unit of the vehicle and the coupling unit of the attachment, so that, when the vehicle and the accessory equipment are mechanically attached, the PTO connecting devices must necessarily be coupled together,
• wherein the vehicle PTO connecting device (151) comprises a coupling shaft (153), a bearing shaft (154) connected to the coupling shaft (153), and a bearing seat, wherein the coupling shaft (153) has outer gear teeth designed with flank clearance designed on one coupling side, and wherein the bearing shaft (154) can swivel by means of a bearing device and an approximately circular shoulder is formed in the bearing seat forming an axial stop for the coupling shaft (153) wherein the bearing seat has a stop plate at a vehicle end, and a vehicle end of the coupling shaft (153), has a cup-shaped recess with inner gear teeth and has, on a coupling end of the bearing shaft, correspondingly designed outer gear teeth to form an anti-rotational lock and wherein coupling shaft and bearing shaft (154) are connected together by means of screw fastenings.
