Adjusting device, air deflecting system, control member and device enabling aerodynamic resistance of a semi-trailer to be reduced
First Claim
1. A device for reducing the air resistance of a tractor and semi-trailer combination comprised of a tractor and a semi-trailer, comprising:
- a displacement device for displacing a fifth wheel coupling in a longitudinal direction of the tractor, the displacement device having a motor drive and a position sensor,a lifting device for raising or lowering the fifth wheel coupling, the lifting device having a motor drive and a position sensor,and further comprised of a wind deflector which is swingably mounted on a cap of the tractor, the wind deflector having a motor drive and a position sensor,wherein the position sensors detect the position of at least the wind deflector and the fifth wheel coupling, with the drives and position sensors being connected to a common control device.

Abstract
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.

20. A device for reducing the air resistance of a tractor and semi-trailer combination comprised of a tractor and a semi-trailer, comprising:
-
a displacement device for displacing a fifth wheel coupling in a longitudinal direction of the tractor, or a lifting device for raising or lowering the fifth wheel coupling, or a combination thereof, and further comprised of a wind deflector which is swingably mounted on a cap of the tractor, wherein the displacement device or the lifting device or the wind deflector or a combination thereof have motor drives and position sensors, with the drives and position sensors being connected to a common control device, which is configured so as to evaluate position signals from the position sensors and to compare said signals with set-point values and then to send control signals to said motor drives.
