A hand crank for a landing gear is described, the hand crank having a main body provided at a first end with a connecting element for fastening the hand crank to an input shaft of the landing gear and formed at an opposite, second end to rotate the hand crank. The hand crank only allows torque to be transmitted from the hand crank to the input shaft if the operator holds the hand crank with at least one hand. A clutch is arranged in the force flow between the first end of the main body and the connecting element, wherein the clutch is held in an open disconnected position and is moved into a force-locked connection position by operating an actuating element arranged at the second end.

The invention concerns a lubricating system for a fifth-wheel traction coupling of a towing vehicle, comprising a coupling plate, the upper side of which has at least one grease discharge aperture which is connected to a lubricating device via a supply line fixed to the coupling plate. The invention addresses the problem of developing a lubricating system for towing vehicles which permits automatic lubrication irrespective of whether a central lubricating system is provided. The invention solves the problem using a lubricating system in which the lubricating device is associated with the fifth-wheel traction coupling and is arranged directly on the fifth-wheel traction coupling or in the vicinity of the fifth-wheel traction coupling.

An air guiding element for improved flow over a gap between a tractive vehicle and a trailer vehicle is described, wherein the air guiding element can be mounted on the tractive vehicle or the trailer vehicle and has a flexible and airtight air cushion which is connected to a filling channel. The problem of providing a largely low-maintenance and operationally safe air guiding element, which can be installed independently of the compressed air supply of the tractive vehicle, for improved flow over the gap between a tractive vehicle and a trailer vehicle is addressed. The problem is solved by an air guiding element in which the filling channel has an air entry opening oriented in the direction of travel (F) on the side of the filling channel facing away from the air cushion, the air entry opening being arranged in such a way that the air cushion is filled exclusively by a dynamic pressure of the relative wind.

An air-conducting system for a tractor and/or trailer is described, wherein at least one of the vehicles has a wind deflector. The problem addressed by the invention was to improve the aerodynamic drag of tractors and/or trailers. The problem is solved according to the invention by an air-conducting system in which the wind deflector is arranged at the rear of the trailer and/or at the rear and/or in the front region of the tractor and can be adjusted depending on the driving speed.

A system is specified for the automatic adjustment of a gap between a tractor vehicle and an attached trailer, with a length-adjustable hitch with a tension tube, at the end of which is arranged a tension lug, while the tension lug can travel in the vehicle's lengthwise axis relative to the tension tube by an actuator along a predetermined travel path, as well as a control unit. The basic problem of the invention was to provide a system with which the gap between tractor vehicle and trailer can be changed automatically in driving operation and depending on the speed, both for articulated and unarticulated trailers. The problem is solved according to the invention with a system in which the control unit is an electronic controller, which is hooked up to a speed pickup for the processing of a speed signal and connected to the actuator.

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. The invention also relates to cartridges for use in the filling system. One of the underlying objects of the invention was that of providing a filling system which can be supplemented by simple workshop means and enables the operator to fill up a lubricating system in a vehicle effortlessly within a short time. This object is achieved by a filling system in which the rod is rotatably mounted with respect to the container and turning of the rod in a predetermined direction of rotation brings about a reduction in the storage volume in the container or a handheld device and in which the rod has means for establishing a rotationally fixed connection with an adaptable turning tool.

A system for reducing the air resistance of a truck, particularly an articulated vehicle, wherein the vehicle comprises a cargo space that is limited downward by a loading floor and in the height thereof by a roof wall spaced apart therefrom. The aim is to provide a system that minimizes the face area of the truck and thus the fuel consumption in dependence on the actual cargo space used. According to one embodiment, the roof wall is height-adjustable opposite the loading floor.

A system for braking a trailer being coupled to a pulling vehicle by means of a coupling device, comprising a supply circuit on the pulling vehicle side, and a brake circuit on the trailer side, wherein the brake circuit is removably attached to the supply circuit by means of at least one plug-in coupling. 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.

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.
