Embodiment Construction

[0041] figure 1A side view of a conventional saddle tractor with a tractor 1 and a semi-trailer 23 connected to the tractor by means of a semi-trailer coupling 2 is shown in a side view when driving straight. The tractor 1 has a driver's cab 25 whose rear wall 25 a forms a clearance 24 with a front edge 26 of the semi-trailer. In this shown position of tractor 1 and semi-trailer 23 , gap dimension 24 is approximately 600 mm.

[0042] The clearance dimension 24 is necessary so that even when the tractor 1 turns, a sufficient distance between the front edge 26 of the semi-trailer and the rear wall 25a of the cab can be guaranteed, as seen from figure 2 as can be seen in the enlarged top view of . With the tractor 1 and the semi-trailer 23 at an angle to each other, the gap dimension 24 is reduced to approximately 250 mm.

[0043] image 3 The tractor is shown in a side view when driving straight ahead, wherein the gap dimension 24 is significantly reduced by moving the semi...

Abstract

The invention relates to a slider for a fifth wheel (2) arranged on a towing vehicle (1), comprising a substructure (3) with at least two guide rails (5) aligned in the direction of travel (4), a displaceable slide (6) carrying the fifth wheel (2) and acting upon the guide rails (5), and a motor-driven drive unit (7). The aim of the invention is to provide a slider which allows the gap width between the towing vehicle and the trailer being adapted to the respective driving situation during travel. For this purpose, the slider is characterized in that the motor-driven drive unit (7) is configured from a hydraulic cylinder (9) connected to a hydraulic circuit (8).

Description

technical field [0001] The invention relates to a moving device for a semi-trailer coupling arranged on a tractor, comprising: a substructure with at least two guide rails oriented in the direction of travel; a movable carriage supporting the semi-trailer coupling And embedded in the guide rail; and the motor drive unit. Background technique [0002] Mobile devices are known, for example, from DE-AS 1780488, EP 0503954A1 or DE 19944684C1. [0003] Furthermore, WO 02 / 070328 A1 discloses a displacement device which has two guide rails with toothed racks, on which a slide bearing a semi-trailer coupling is displaceably supported. A locking device with a stop slider engaged with the rack is arranged on the slide seat. [0004] The previously known mobile devices are designed to adjust the distance between the tractor and the semi-trailer before starting to drive. However, it has been shown that the gaps or gaps that occur between the semi-trailer and the driver's cabin of the...
