Embodiment Construction

[0049] figure 1 A side view of the drawbar guided low ride flatbed 10 is shown. The vehicle 10 has a drive unit 12 with steered and driven wheels 14 . The drive part 12 has a drawbar 16 with a drawbar head 18 , a drawbar tube 20 and a drawbar coupling 22 . The drawbar 16 is pivotable about an axis extending horizontally in the drawbar coupling 22 . The position shown by the dotted line of the drawbar 16 corresponds to an approximately horizontal position and produces a lift of the load part 24 . The load part 24 has two load forks 26 which are figure 1 is shown in the position used to accommodate the drop of the load. The raised position of the load fork 26 is shown in dashed lines. Via the drawbar 16 not only the lifting of the load fork 26 is controlled, but also the steering of the driven wheels 14 . To this end, the drawbar 16 is pivotable about a vertical axis V. As shown in FIG. like figure 1 The vertical axis V shown in can extend through the midpoint of the dri...

Abstract

The invention relates to a ground surface transport tool having a draw bar. The draw bar has a draw bar head, a draw bar tube extending longitudinally, and a draw bar connection member; the draw bar tube can be arranged in the draw bar connection member in a manner that the draw bar tube may pivot around a horizontal axis, and a spring component is arranged in the draw bar connection member, wherein the spring component is arranged on the draw bar connection member in a manner that the spring component protrudes out of the draw bar tube so as to pre-fasten the draw bar tube on a limited position thereof; the spring component has a gas spring and a gas spring guide member; the gas spring guide member holds an end of the gas spring, and has a supporting surface of a pin in the direction perpendicular to the longitudinal direction of the draw bar tube, at a side on the front of the gas spring, wherein the pin has a bent supporting surface, and the gas spring guide member occupies the limited position of the pin in the pre-tensioning condition of the spring.

Description

technical field [0001] The invention relates to a ground vehicle with a drawbar having a longitudinally extending drawbar tube with a spring element which adjusts the drawbar into a predetermined position. Background technique [0002] In ground vehicles with a drawbar it is known to arrange a spring element in the interior of the drawbar tube. The spring element cooperates with the drawbar arm at one end and is coupled to the opposite end in a fixed manner on the vehicle, so that the drawbar arm is prestressed by the spring, for example into an approximately vertical position. [0003] When installing the spring element, it is particularly difficult to fasten the spring element in the drawbar tube, since the drawbar is formed as a closed tube in which it is not visible from the outside and protected Restricted imports are installed. Persons who are just new to installation are generally not able to carry out this work step easily and are complex. Contents of the inventi...
