Abstract: Disclosed is a plug-in coupling system for joining cables between a tractor and a trailer. The invention also relates to the individual components, i.e. the semitrailer coupling and the plug-in connector on which the invention is implemented. The cables between the tractor and the trailer are usually plugged into each other by hand. Automatic systems have not been successful on the market so far. The aim of the invention is therefore to create a plug-in coupling system which allows the supply cables to be connected in a comfortable and operationally safe manner when the trailer is joined to and disconnected from the tractor. Said aim is achieved, among other things, by disposing the socket in a stationary manner below the insertion hole on the semitrailer coupling while arranging the contact points of the plug below the king pin on the plug-in connector.

The invention is characterized in that said actuating device which is designed to move the slide, comprises a first powered device. Additionally, at least one first position sensor is arranged to detect the position of the slide, at least said first position sensor being connected to a control device.

Abstract: A description is given of a filling system for the metered delivery of a lubricant, comprising a container for receiving the lubricant, wherein a rod interacts with the container, is mounted movably with respect to it and forces the lubricant out of an outlet opening arranged in the container.

Abstract: The invention describes an arrangement of lubricating grease inside the housing of a gear unit with rotatable components, particularly the gear unit of a jack. It also describes a grease pouch for receiving lubricating grease and a method for lubricating the gear unit with lubricating grease. Since the gear units are often not transported in their installed position, oil that has separated from the lubricating grease may leak from any gearbox openings. Thus, one of the objects of the invention was to provide an arrangement of lubricating grease in the housing of a gear unit, which on the one hand provides lubrication of the gear unit so that it is ready for operation in its delivery condition and on the other hand effectively prevents the oil separated from the lubricating grease from leaking prior to initial startup. This object is attained by enclosing the lubricating grease within at least one grease pouch prior to initial startup of the gear unit.
