Problems solved by technology

Each row of holes therefore has more than twice the number of bolt holes required for the actual fastening operation, resulting in more than half of all holes located below and / or above the fastening bolts provided during assembly being unused, ie remain idle, and in addition to seeing a noticeably thick weld on the front side, the appearance of the support is also negatively affected

Embodiment Construction

[0023] exist Figures 1 to 3 as well as Figure 5 The supports 10 shown in are fastened in pairs to the front region of the chassis of the semi-trailer 11 and are retracted in the transport situation, ie in a shortened state. The support 10 is extended before the semi-trailer 11 is separated from the articulated truck.

[0024] Since the supports 10 in each pair have the same configuration, only one support 10 will be described.

[0025] The support 10 has an outer support tube main body 12 and an inner support tube 13 installed in the outer support tube main body 12 in a longitudinally movable manner.

[0026] The outer support tube body 12 comprises a channel profile 14 with two opposing wing-like flanges 14a, and a rear wall 15 welded to the channel profile 14, so that a guide with a square cross section is formed therein. The guide channel, the inner support tube 13 also having a square shape, is fitted within the guide channel with a certain amount of play. Also, the ...

Abstract

The present invention relates to a height-adjustable support 10 for semitrailers 11 having a stationary outer support tube body 12 and an inner support tube 13, which is arranged in a longitudinally displaceable manner therein. The outer support tube body 12 is of trough-shaped design, the outer support tube body 12 having a U-shaped region 25 and the open region of the U-shaped region 25 being closed with a rear wall 15 and therefore forming a guide channel for the inner support tube 13 guided therein.

Description

technical field [0001] The present invention relates to a height-adjustable support for a semi-trailer or the like. Such supports are usually arranged in pairs at the front area of ​​the semi-trailer. Background technique [0002] In the brochure 098060 from haacon of D-97895 Freudenberg one can see a generic called "Separate Support" S 2000. [0003] In this case, the outer support tube body, in which the inner support tube with a square cross section is guided and supported, has a longitudinal profile with a U-shaped cross section, and the flank ends of the outer support tube body (the limb end) are welded to a continuous threaded plate having approximately the same length and protruding on both sides. [0004] In this design, the resulting deflection forces, especially the large shear forces generated during the removal of the support load, pass through the force flux before being transmitted into the semi-trailer chassis via the bolted joints. ) must first of all be ...
