Plug-in system for trailer vehicles
A plug-in system for trailer vehicles provided with an automatic coupling system of the supply lines, including a plug ( 1 ) supporting the line contacts ( 1 a ) and a socket ( 2 ). The plug ( 1 ) has guide elements ( 4 ) that actively engage when approaching the guide elements ( 5 ) of the socket ( 2 ). The centering of a plug system for an automatic coupling system of supply lines on an articulated train is achieved by the guide elements ( 4 ) include a main guide pin ( 6 ) and at least one centering pin ( 7 a , 7 b ) arranged at a distance therefrom. At least the centering pin ( 7 a , 7 b ) and/or the associated guide element ( 5, 9 ) is elastic in the radial direction.
1. A plug-in system for trailer vehicles with an automatic coupling system of the supply lines, comprising a plug supporting the line contacts and a socket, wherein the plug has guide elements which actively engage when approaching the guide elements of the socket, wherein the guide elements comprise a main guide pin and at least one centering pin that is spaced apart therefrom, and wherein at least the centering pin and/or the associated guide element allows an elastic movement is elastic in the radial direction with respect to the main guide pin.
2. A plug-in system for trailer vehicles with an automatic coupling system of the supply lines, comprising a plug supporting the line contacts and a socket, wherein the plug has guide elements which actively engage when approaching the guide elements of the socket, wherein the guide elements comprise a main guide pin and two centering pins arranged on both sides of the main guide pin that are spaced apart therefrom, wherein at least the centering pin and/or the associated guide element is elastic in the radial direction.
3. The plug-in system according to claim 1 or 2 , wherein the main guide pin and the at least one centering pin are dedicated to the plug.
4. The plug-in system according to claim 1 or 2 , wherein the guide elements of the socket are formed as receiving openings.
5. The plug-in system according to claim 4 , wherein the receiving opening provided for receiving the main guide pin has an inner diameter (d 1 ) which is complementary to the outer diameter (d 2 ) of the main guide pin.
6. The plug-in system according to claim 4 , wherein the receiving opening provided for receiving the at least one centering pin is formed with an inner diameter (d 3 ) which is complementary to the outer diameter (d 4 ) of the at least one centering pin.
7. The plug-in system according to claim 6 , wherein the receiving opening has a breakout to the respective nearest lateral wall face.
8. The plug-in system according to claim 4 , wherein the receiving openings for the centering pins are formed from recesses of the socket which have a planarly extending horizontal wall section and which each are formed on the upper and/or lower side of the socket.
9. The plug-in system according to claim 8 , wherein the recesses open out into the lateral wall faces.
10. The plug-in system according to claim 1 or 2 , wherein the plug and the socket are made of plastic.
11. The plug-in system according to claim 1 or 2 , wherein the main guide pin and the at least one centering pin are made of metal.
12. The plug-in system according to claim 1 or 2 , wherein the main guide pin and the at least one centering pin extend in axial direction throughout the entire length of the plug.
13. The plug-in system according to claim 1 or 2 , wherein the main guide pin and the at least one centering pin are attached to the rear bottom wall.
14. A plug-in system for trailer vehicles with an automatic coupling system of the supply lines, comprising a plug supporting the line contacts and a socket, wherein the plug has guide elements which actively engage when approaching the guide elements of the socket, wherein the guide elements comprise a main guide pin and at least one centering pin that is spaced apart therefrom, wherein at least the centering pin and/or the associated guide element is elastic in the radial direction, the at least one centering pin is surrounded within the plug by an annular space opening out on the front side and is supported with an elastic element just before the exit out of the annular space on the wall of the same.
15. The plug-in system according to claim 14 , wherein the elastic element is an O-ring.
16. A first plug half according to claim 1 or 2 or 14 , wherein the main guide pin protrudes further with respect to the front side than the at least one centering pin.
17. The plug-in system according to claim 1 or 2 or 14 , wherein the plug is arranged on a pivot wedge which is formed complementary to the insertion opening of a fifth wheel.
18. A first plug half with guide elements which are formed thereon and which, when approached by guide elements of a second plug half, can actively engage with the same, wherein the guide elements comprise a main guide pin and at least one centering pin laterally spaced apart therefrom, wherein the at least one centering pin is elastic or elastically mounted in the radial direction, wherein the plugged state of plug and socket the range of movement is limited by the main guide pin to two degrees of freedom and lateral tolerances between the plug and the socket are compensated by an adequate deformaton.
