A device for adjusting a fifth wheel, comprising a displacement device provided with two guide rails placed on the vehicle, in particular on a tractor semi-trailer combination in the longitudinal direction thereof, said guide rails whereon a slide may be installed capable of being moved by means of an actuating device, said actuating device being designed such that, upon a displacement, the positive connection between the guide rails and the slide is maintained. The 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.

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. The at least one grease pouch is inserted into the housing of the gear unit so as to contact the components. Upon initial startup the at least one grease pouch is torn open by the action of the components and releases the lubricating grease.

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.

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. These objects are attained by arranging the first sensor detecting the kingpin in the area of the locating hole and configuring the second sensor as a magnetically sensitive sensor that interacts with a magnet mounted on the operating lever. The two sensors are based on different mechanisms of action.
