Drop side for truck bridges

The innovation relates to a side wall, in particular for truck bridges, consisting of at least two / one parallel to each other arranged Leichtmetallplankar., which by a plug connection are held together in the same plane, which connection by the facing, channel-shaped Longitudinal edges of the planks and a fixing member inserted into the cavity formed by the two grooves will be produced.

In the known, assembled from planks board walls of this type was originally the fixing member by a Pin formed with full cross-section, the inevitable dimensional deviations in the manufacture of the planks and the pins (Manufacturing tolerances) but led to the pin Often it was either too thick and could not be inserted into the cavity at all, or that it was too small Diameter and was therefore not given a tight fit. could.

DT-Gm 1,995,812 describes it as therefore recommended to use au instead of a pen with vollen- · area * a tubular portion having a longitudinal slot of a certain width. If the outer diameter of the pipe section was kept somewhat larger than the inner diameter of the cavity, it was hoped _for by the elasticity of which should receive the tubular portion in the radial direction through the slot to achieve a solid seat of the Pixicrorgans and yet a simple driving of the organ to enable*

It turned out, however, that even with this solution, the introduction of the fixation organ caused difficulties, since that too Slotted tube did not have sufficient elasticity in the radial direction with certainty, or only satisfied if on all parts of the tolerance requirements were made.

It has now been found that the problem of the fixing organ can be solved in a satisfactory manner if instead of the pin with full cross-section or the slotted tube a helically rolled ribbon spring is used.

The attached drawings explain the innovation in the sense of an example. They show:

The two planks 1 and 2 have those described in DT-Gm 1 993 812 Design of their longitudinal edges, whereby the cavity 3 is formed. For assembly reasons, this has preferably circular cross-section; however, other cross-sectional shapes are also conceivable. In this cavity 3 is the helically rolled ribbon spring 4 introduced. This spring 4 can, for example, consist of a steel band or such be made of a suitable aluminum alloy. The thickness and width of the belt depend on the inside diameter of the cavity 3. The outer diameter of the finished, ready-to-install helix must be larger than the largest possible Diameter of the cavity 3. In this way it is achieved that the spring 4 is securely attached to the inner wall of the cavity pressed on and thus has a firm fit.

The introduction of the spring 4 into the cavity 3 is expedient with the help of a hand drill, which instead of the drill one at its front, free end in the axial direction slotted rod 5 of the necessary length, i.e. min

The spring is screwed into the cavity 3. Through this operation, the coil in the cavity is rolled a little tighter so that it slides easily into the cavity.After the turning operation has stopped, the spring * presses itself firmly against the inner wall in an effort to return to its original outer diameter, i.e. to expand in the radial direction of the cavity and thus receives a tight fit.
