Embodiment Construction

[0026] Refer to attached figure 1 , the beam 1 according to the invention comprises a main body 1a connected at each end to a flange 2a, 2b, 2c, 2d respectively.

[0027] like Figure 4 As shown in the example of , the cross member 1 is assembled with the side members 11 and 12 of the vehicle frame through the flanges 2a, 2b, 2c, 2d.

[0028] back to figure 1 In this case the beam has a main body 1a, characterized in that the bottom edge 4a of the side part 4 is almost solid.

[0029] Compared figure 1 and figure 2 It can be seen that the bottom edge 4a of the side part 4 of the beam can be further flared outwards, making the main body 1a of the beam thinner.

[0030] The main body 1a of the cross beam has different shapes according to the weight of the cross beam installed on the vehicle frame, so that the materials used can be optimized and the weight of the cross beam itself can be reduced.

[0031] The presently described beam 1 is made of a single piece having a bo...

Abstract

This invention relates to a method for obtaining a stiffening cross member for a vehicle frame, in particular heavy vehicles, the cross member obtained with such method, and also a vehicle frame comprising such cross member. The method according to this invention allows to obtain a cross member made of a single piece, and to obtain cross members having different profiles and dimensions according to what is required, using the same semi-finished product.

Description

technical field [0001] The present invention relates to a method of manufacturing vehicle frames, especially stiffening beams for heavy vehicle frames, the beams produced by this method and vehicle frames comprising such beams. Background technique [0002] In the prior art, the frame of a heavy vehicle used for transporting goods and / or passengers is usually composed of side beams, and the side beams are fastened by crossing one or more cross beams perpendicular thereto. [0003] In the prior art, the fastening beam is usually obtained by joining multiple plate components by welding or other fixing means. The cross beams known in the prior art are made of a beam-shaped body having at its ends two flanges for connecting the side beams to the vehicle frame. [0004] Manufacturing the beam by joining multiple parts is not only complicated in process, but also costly in steps. [0005] Therefore, even though the part itself is simple, the assembly process of a beam containing...
