The aim of the invention is to improve a known coupling system for the supply lines in such a way that the coupling of the supply lines is even faster and more comfortable. To this end, the coupling is provided with at least one first sensor for detecting the locking state and the movement of the supply bracket is triggered by a signal from the first sensor. | 07-23-2009 |
20090230655 | Displacement Device for a Fifth-Wheel Traction Coupling - A displacement device for a fifth wheel traction coupling with two base bars and a fifth wheel traction coupling supporting top part which includes two bearing chocks which are slidingly fixed to the base bars and telescoping in a locked position thereof into each base bar by means locking elements with the aid of a rack rail. The known per se sliding devices are expensive due to the production of the base bars, since the rack rails are provided with a toothed profile prior to be welded. A low-cost sliding device is producible in a simple manner. For this purpose, at least one base bar is provided with spaced rest windows on the axial extension thereof for receiving the locking elements. | 09-17-2009 |
20130168946 | BEARING ASSEMBLY OF A FIFTH WHEEL COUPLING - A bearing assembly having a bearing block of a fifth wheel coupling. The bearing block has at least one vertical fastening flange. The tractive unit has a frame element, which has a vertical section. The vertical fastening flange is connected to the outside of the vertical section by a screw connection. A component, on which the vertical fastening flange is supported at least in the vertical direction, is fastened to the vertical section. | 07-04-2013 |

20100059967 | CONNECTOR BRACKET FOR A SEMITRAILER OF A SEMITRAILER TRUCK - The invention relates, inter alia, to a connector bracket for a semitrailer of a semitrailer truck. Said connector bracket comprises a support element which can be swiveled about a bearing and a connector arranged inside the support element, the support element having a casing frame with a section that is complementary to an insertion opening of a fifth wheel. The aim of the invention is to provide a connector bracket or a plug-in coupling which is highly reliable even under adverse external conditions. This aim is achieved, inter alia, by the connector bracket according to the invention, wherein the casing frame can be displaced in relation to the connector by contact with the insertion opening, thereby displacing the connector from a closed standby position to an open coupling position. | 03-11-2010 |
