BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Further advantages and features of the present invention will be apparent from the following description with reference to the figures. Therein, individual features of the embodiments shown may also be used in other embodiments, unless expressly excluded. It is shown in:

[0022] FIG. 1 is a perspective view of part of a kingpin arrangement;

[0023] FIG. 2 is a side elevation view of the kingpin arrangement; and

[0024] FIG. 3 is a top plan view of the kingpin arrangement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] FIG. 1 shows a kingpin arrangement 1 having a rotor 20 and a stator 30. The rotor 20 has a plug connector 22, which in turn has a plurality of guide pins 24 and a plurality of electrical contacts 28. Therein, in the embodiment shown, the rotor 20 is mounted so as to be completely free to rotate relative to the stator 30. The stator 30 has a connection 34 which, at least in an installed state, is connected in an energy-conducting manner to a distribution network of a trailer. In order to enable an energy conduction from this connection 34 to the electrical contacts 28 of the plug connector 22, the kingpin arrangement has an energy transmission device 26. Therein, this energy transmission device 26 has a plurality of slip rings 44 on the rotor side. In the embodiment shown in FIG. 1, the slip rings 44 each have a center which lies on the axis of rotation, and the slip rings 44 are also arranged axially with respect to the axis of rotation. In order to allow electrical energy to flow from these slip rings 44 to the electrical contacts 28 of the rotor 20, the rotor 20 has current collectors 42 which are resiliently mounted within the rotor 20. Therein, the current collectors 42 make electrically conductive indirect and/or direct contact with a respective slip ring 44 in order to achieve an energy conduction from the plug connector 22, in particular its electrical contacts 28, to the connection 34.

[0026] FIGS. 2 and 3 show further embodiments of a kingpin arrangement 1. In FIG. 2, a side view of a kingpin arrangement 1 is shown and in FIG. 3 a top view is shown, wherein the embodiment shown in FIG. 2 can in principle match the embodiment shown in FIG. 3. The kingpin arrangement 1 has a kingpin 10, a stator 30 and a rotor 20. The rotor 20 has a power connection 22 in the form of a plug connector 22. The plug connector 22 has at least one guide pin 24. The connection 34, which is located on the stator 30, is connected to the energy connection 22 in an energy-conducting manner via an energy transmission device 26. The energy transmission device 26 has a plurality of slip rings 44, each of these slip rings 44 having a center M. The centers M of the slip rings 44 all lie on the axis M, as indicated in FIG. 2. A plurality of pneumatic lines 36 lie in the center of the slip rings 44, their freely extending ends being arranged concentrically to the axis of rotation.
