Abstract: A method and to a system for controlling a sliding device for a fifth wheel coupling arranged on a towing vehicle, wherein the sliding device includes a substructure having at least one guide rail oriented in the driving direction, a movable slide, which supports the fifth wheel coupling and engages on the guide rail, and a control unit, to which a motorized drive unit for moving the slide and an actuator for fixing the slide relative to the guide rail are connected. The aim was to provide a method and a control system with which a sufficiently large gap width (W) can be set between the towing vehicle and the trailer in a timely manner. This is achieved, among other things, by a method in which a distance measurement is performed to detect an obstruction in front of the towing vehicle, the signal of the measurement is processed into a control signal in the control unit, and a start-up of the motorized drive unit and/or the actuator is initiated therewith.

Abstract: A coupling system for connecting supply lines between a trailer and a tractor vehicle, with a socket which is arranged on the tractor vehicle and a support element, having a plug, which is arranged on the trailer. The invention is based on the problem of providing a robustly operating coupling system in which an automatic connection of all of the provided supply lines is possible. The problem is solved by a coupling system in which the socket is arranged in a positionally fixed manner on the tractor vehicle, the plug is guided in a laterally moveable manner in the support element, and the plug can be placed into a connecting position with the socket by an actuator which is arranged on the tractor vehicle.

The invention is based on the object of providing a system for braking a trailer, wherein the risk of an uncontrolled vehicle movement, at least of the trailer vehicle, is reduced. The problem is solved according to the invention by means of a system wherein disposed within the brake circuit is a ventilation valve that can be remotely controlled by the pulling vehicle.

Abstract: A method is described for the mounting of a bearing block of a coupling plate on a mounting plate, with the bearing block having a bridge-like shape, being provided with bores at its opposite front and rear ends to accommodate fixing screws and being kept in place on the mounting plate by means of the fixing screws, and the coupling plate engaging with the bearing block in a central area, with the attachment of the bearing block to the mounting plate comprising at least one additional form fitting element. The invention was based on the task of providing a secure attachment of a self-supporting bridge-like bearing block to a mounting plate even under the extreme operating forces that are to be expected. The task is solved in accordance with the invention by means of a method in which by tightening the fixing screw together with the at least one form fitting element causes a deformation of the mounting plate.

Abstract: The invention relates to a coupling system for connecting at least one supply line between a towing vehicle and a trailer, the first end of said at least one supply line being attached to the towing vehicle in a fixed manner, and the second end thereof comprising a connector that can be connected to a supply line interface of the trailer. The aim of the invention is to provide a coupling system for the supply lines, by which means a complicated operation between the trailer and the driver's cab of the towing vehicle is avoided. To this end, a coupling system is provided, whereby the supply line interface can be displaced out of a traveling position into an operating position.

Abstract: A line magazine for a supply line on a semimounted trailer with a king pin and a wedge connector pivoted on the king pin is described. The underlying problem of the invention was to provide a line magazine which prevents the supply line from hanging down in a mechanically simple way, while on the other hand it provides a constant pretensioning of the supply line. The problem is solved according to the invention with a line magazine that comprises a housing and a drum disk mounted in the housing and able to rotate, while the drum disk is preloaded by a spring element and the supply line engages by its front segment of line with the wedge connector and is led out from the housing by its rear segment of line in fixed manner.

Abstract: A support device for semi-trailers including a leg which has a receiving device, on its lower end. The support leg has a base element with a base plate, whereby the base element is fastened to the base receiving device by a fixing device. The base element is connected by a pivot bearing device with the support leg, whereby the pivot bearing device is located below the damping element. The compression of the damping element is therefore fully decoupled from the pivoting movement of the base element.

Abstract: A landing gear assembly for a semitrailer includes a pair of legs that may be simultaneously raised or lowered by turning a single crank. Each of the legs is configured to be able to be mounted in either an inboard or outboard configuration. This is achieved by providing both sides of each leg with no protrusions that extend beyond the space provided in the mounting bracket and the mounting hole used to connect the landing gear to the semitrailer. The gear assembly of the landing gear includes a unique floor base that receives and supports the input shaft. A cover is used to support the input ends of the input shaft and the output shaft. The cover is connected to the input side of the upper tube of the leg and allows the gear assembly to be easily assembled within the perimeter of the upper leg.
