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.

Abstract: A method for the transmission of electrical, pneumatic, or hydraulic energy between a first vehicle and a second vehicle, coupled thereto, for example a tractor vehicle and a trailer and an energy transmission system. The aim of the invention is development of a method and an energy transmission system permitting an operationally-secure driving condition over a long period even with a partly or completely damaged plug coupling system. Said aim is achieved by means of, amongst other things, a method whereby the energy in the energy distribution line is introduced from the energy supply line in a controlled manner.

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.

Abstract: A support jack, in particular for supporting semitrailers, includes a vertically telescopically displaceable supporting element having an outer sleeve and an inner sleeve, each sleeve having a rectangular cross-section with four sidewalls in each case. At least one sidewall at least of the inner sleeve has an additional wall plate. Another alternative proposes that at least one sidewall at least of the inner sleeve consists of a wall plate which the two adjacent sidewalls are fixed. An arrangement of such a support jack on the lower side of a vehicle is also described.

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.
