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.

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.

In order to improve handling of the sliding device, at least one locking sensor (S1) for detecting the locked position is provided. Said locking sensor (S1) is connected to a display device and/or to the vehicle electronics.

Abstract: The invention relates to a system for lubricating a closing mechanism on a saddle coupling comprising a closing mechanism which is arranged on the lower side of a coupling plate and which comprises at least one closing hook and/or closing bar, provided with a coating, and a fat reservoir which is connected to the closure hook by means of a lubricating line. The invention also relates to a coating of individual components of the system, i.e. the closing hook and the closing bar, in addition to the use of a coating. The invention is characterized in that the coating of the closing hook and/or the closing bar is embodied as a sliding coating.

Abstract: An arrangement of a motor on twin landing gears is described. The landing gears are interconnected via a connecting shaft and can be telescoped by starting up the motor. To minimize damage to the motor and at the same time to ensure cost-effective production, it is provided that the motor with its driveshaft engages with the connecting shaft and is supported on a component that is fixed relative to the motor.

Abstract: A device is described for indicating the locking state of a fifth wheel coupling and an arrangement of a first and a second sensor. According to the prior art, the first sensor is arranged on the underside of the locking latch and monitors the position of the kingpin in relation to the locking latch. A second sensor that is used is an inductive proximity switch that monitors a safety mechanism against loosening. In practice, this type of positioning of the first sensor has led to damage of the locking latch and the first sensor, while the signals of the second sensor were often false signals. Thus, the object of the invention is to provide a device for indicating the locking state, which maximizes operational availability and minimizes false signals. A further object of the invention is to optimize the arrangement of the first and the second sensor.

Abstract: A carrier assembly for a fifth wheel mounted on a semi-trailer tractor includes a pair of generally parallel spaced rail assemblies, each comprising a bed plate, a rack of teeth superimposed over the bed plate and a rack cover plate superimposed over the rack of teeth. Bolts extend through the rack cover plate, rack of teeth and bed plate. A slider assembly includes a pair of spaced generally parallel axial elements superimposed over respective bed plates and connected by a transverse element. The slider assembly supports a tooth engaging mechanism that selectively engages the rack of teeth and is spring biased and mechanically biased toward a locked position. Rear stops are removably attached to the carrier assembly. Projections on the bed plate and rack cover plate extend into apertures in the rack of teeth to resist shear forces.

Abstract: A fifth wheel coupling comprising essentially a fifth wheel plate and a pair of pillow blocks for the attachment on the frame of a truck tractor. The fifth wheel plate pivots around an axis in relation to the pillow blocks and on its underside, is equipped with a pair of hollow cylindrical bearing troughs, while the pillow blocks have corresponding cylindrical bearing surfaces. Below the bearing surface, the pillow block is equipped with an eye for the penetration of an attachment bridge. The object is to reduce the weight of fifth wheel couplings of this type and to lower the manufacturing cost without thereby complicating the assembly or having to omit an adjustment to differing mounting widths.
