Embodiment Construction

[0020] figure 1 Shown is a schematic side view of the tractor 2 and the trailer 3 fastened to the tractor 2 via the trailer coupling 4 and the central journal 19 . Several electrical consumers are provided on the trailer 3 and must be supplied with electrical energy and compressed air. As regards the load, there are trailer brakes 23 , air suspensions 24 and supporting winches 22 mounted in pairs and powered by electric energy, which additionally receive control signals from the tractor 2 via a bus system not shown further.

[0021] Both the tractor 2 and the trailer 3 are provided with an automatic line coupling system 5 , which in the present illustration contains components shown enlarged on the trailer connector 4 . The trailer 3 is mechanically connected to the tractor 2 via a central journal 19 fastened in the trailer coupling 4 . Engaging on the central journal 19 is a rotatably arranged socket wedge 20 , which protrudes rearwardly out of a wedge-shaped opening, not s...

Abstract

A system for connecting supply lines between a tractive vehicle and a semi-trailer that can be coupled to the latter, a semi-trailer coupling and an automatic line coupling system comprising at least one connector jack being situated on the tractive vehicle and the semi-trailer having at least one supply circuit comprising a first supply console for connecting to the tractive vehicle and for receiving a plug-in element that is located on at least one supply line of the tractive vehicle and / or a plug that is configured to fit the connector jack. The aim of the invention is to provide a system for connecting supply lines for tractive vehicles, comprising an automatic line coupling system that permits the coupling of conventional semi-trailers. To achieve this, a second supply console is located on the tractive vehicle and is permanently connected to the connector jack of the line coupling system and the plug-in element can be selectively connected to the first or second supply console.

Description

technical field [0001] The invention relates to a system for connecting a supply line between a tractor and a trailer, to which the trailer can be coupled, wherein the tractor is provided with a trailer connector and an automatic line coupling system with at least one socket, the trailer There is at least one supply circuit which, for connection to a tractor, has a first supply arm for receiving a plug element arranged on at least one supply line of the tractor and / or for receiving a plug configured complementary to the socket. Background technique [0002] In the large number of saddle tractors in use today, the tractor and the trailer are connected to each other by flexible supply lines, through which the electric and pneumatic power supply of the trailer can be realized. In addition, it is possible to confirm the control signal or ensure the hydraulic supply of the trailer via the corresponding supply line. The coupling of the supply line needs to be carried out manually...
