Embodiment Construction

[0049] In the trailer coupling devices 10 , 110 shown in the figures, partially identical or functionally identical components are provided, for which reason the same or similar reference numerals are used in this regard. In order to illustrate the difference between the embodiments 10 and 110, reference numerals differing by 100 are generally used.

[0050] The trailer coupling 10 includes a bracket assembly 11 with a cross member 12 which extends, for example, transversely at the rear of the motor vehicle 90 . The cross member 12 is fastened to the body 91 of the motor vehicle 90 , for example via side members. The side members (not shown) are screwed together with the body 91, for example. The side member can extend laterally on the body in the direction of travel along the longitudinal direction of the motor vehicle 90 on the outer side or can also be arranged on the rear side of the vehicle.

[0051] The bracket assembly 12 is thus connected to the body 91 of the motor ...

Abstract

The invention relates to a trailer coupling (10) having a support arrangement (11) that is fastened, or can be fastened, to a motor vehicle (90), on which a bearing (13) is mounted, wherein on the bearing (13) a coupling element (20), in particular a coupling arm (23), can be moved by means of an adjustment movement between a use position (G) which is suitable for coupling a trailer (95) or load carrier (195) to the coupling element (20), and in which when the trailer coupling is mounted on the motor vehicle (90) the coupling element projects rearwardly of the motor vehicle (90), and a non-useposition (N) in which the coupling element is advantageously moved back behind a bumper (92) of the motor vehicle. On the coupling element, a connecting device (60) for connecting an on-board network(99) of the trailer or load carrier (195) to an on-board network (93) of the motor vehicle is provided. The connecting device (60) is connected, or connectable, to the on-board network (93) of the motor vehicle by means of a cable (40) comprising a flexible cable section, which at a first longitudinal end (45) is attached to the coupling element in a positionally fixed manner with respect to thecarrier arrangement (11), and at a second longitudinal end (46) is attached to the coupling element in a positionally fixed manner, and which follows the movement of the coupling element between the use position (G) and the non-use position (N). According to the invention, the trailer coupling comprises a winding device (35) for winding a winding section (49) of the cable section (44) onto a cablereel (50) when the coupling element is moved between the use position and the non-use position.

Description

technical field [0001] The invention relates to a trailer coupling having a fixed or fixable carrier assembly on the motor vehicle, on which a bearing is arranged, wherein a coupling element, in particular a coupling, is attached to the bearing. The arm is displaceable by means of a displacement movement between an in-use position suitable for coupling a trailer or load beam to the coupling element and a non-use position in which the coupling element is on the trailer The coupling device, in the state mounted on the motor vehicle, projects rearwardly to the front of the motor vehicle, and wherein in the non-use position the coupling element is advantageously displaced back to the bumper of the motor vehicle rear, wherein a connecting device is arranged on the coupling element for connecting the on-board electrical system of the trailer or of the load beam to the on-board electrical system of the motor vehicle, wherein the connecting device is by means of a line Connected or c...
