DETAILED DESCRIPTION

[0034] The embodiments of the present disclosure described below are not intended to be exhaustive or to limit the disclosure to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art may appreciate and understand the principles and practices of the present disclosure.

[0035] FIG. 1a shows three agricultural base vehicles 10 in the form of tractors, in each case without a vehicle cab 12. Together the three base vehicles 10 form a vehicle fleet 14. In the embodiment shown a single vehicle cab 12 is available for this vehicle fleet 14.

[0036] Depending on a predetermined operation of the relevant base vehicle 10, the vehicle cab 12 is selectively received in a receiving region 16 of a supporting structure 18 of the base vehicle 10 or removed or kept at a distance therefrom. In FIG. 1a the base vehicle 10 to the far left is selected as a guide vehicle or leading vehicle 20. The vehicle cab 12 is assigned to this guide vehicle 20.

[0037] At least some of the technical functions (for example, steering, braking) of the base vehicle 10 are also able to be performed without a received vehicle cab 12. In this regard, the technical functions of the guide vehicle 20 may also be performed for example in an automated, autonomous or remotely controlled manner, in each base vehicle 10 following the guide vehicle 20.

[0038] Optionally, a vehicle cab 12 or a functional device, not shown here, (for example, a storage container, tank, technical unit) may be received in the receiving region 16.

[0039] A pivotally movable and multi-armed lifting device 22 is mounted on the supporting structure 18. The lifting device serves for receiving the vehicle cab 12. To this end, the base vehicle 10 is initially moved toward the vehicle cab 12 (FIG. 2a). Then, a free end 24 of the lifting device 22 is secured to the vehicle cab 12 mounted on a bearing frame 26. The vehicle cab 12 is subsequently lifted into the receiving region 16 (FIG. 2b). The vehicle cab 12 is correspondingly removed again from the base vehicle 10 by the lifting device 22.

[0040] FIG. 3 schematically shows the base vehicle 10 and a corresponding vehicle cab 12. The receiving region 16 of the supporting structure 18 of the base vehicle 10 has four coupling interfaces 28, 30, 32, 34 which are coupled to corresponding cab interfaces 28′, 30′, 32′, 34′. The interfaces 28, 28′, 30, 30′ effect a releasable blocking (for example, mechanical, hydraulic, electromagnetic) of the vehicle cab 12 on the supporting structure 18. However, the interfaces 32, 32′, 34, 34′ relate to technical functions of the base vehicle 10 which, when the vehicle cab 12 is received, may be performed by a user from the vehicle cab 12 via control units 36, 38 which are connected to the cab interfaces 32′, 34′.

[0041] The supporting structure 18 is configured such that the vehicle cab 12 is able to be received so as to be selectively oriented for a forward direction of travel 40 or for a rearward direction of travel 42 of the base vehicle 10. Additionally, the received vehicle cab 12 may be rotatably mounted on the supporting structure 18 relative to a cab vertical axis 44. To this end, the vehicle cab 12 has a suitable construction which permits both the releasable blocking thereof and the rotatability thereof relative to the supporting structure 18.

[0042] The cab vertical axis 44 runs parallel to a vehicle vertical axis 46 of the base vehicle 10. The aforementioned rotatability of the vehicle cab 12 permits the user-friendly orientation thereof, both for forward travel and for rearward travel of the base vehicle 10.

[0043] FIG. 4 schematically shows individual components of the base vehicle 10 for controlling the lifting device 22. The lifting device is controlled by a control device 48 as a function of a predetermined operation of the base vehicle 10, in order to receive or to remove the vehicle cab 12 as already described. The predetermined operation of the base vehicle 10 is represented by control data or control signals S_BE which are processed in the control device 48. The lifting device 22 is controlled in terms of movement by the control device 48 as a function of the control data S_BE.

[0044] The control data or control signals S_BE are generated as a function of input data 50 on the control device 48. The input data 50 are predetermined, for example, by the driver or user via a user interface 52. Alternatively or additionally, the input data 50 are predetermined by a sensor unit 54 on the vehicle side or a data interface 56 or a bus system 58 of the base vehicle 10. The data interface 56 is configured for the transmission of signals from an external signal source (for example, remote control, mobile telecommunication connection).

[0045] While embodiments incorporating the principles of the present disclosure have been disclosed hereinabove, the present disclosure is not limited to the disclosed embodiments. Instead, this application is intended to cover any variations, uses, or adaptations of the disclosure using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this disclosure pertains and which fall within the limits of the appended claims.
