[0018] The utility model will be further described below in combination with the drawings.

[0019] The directions involved in the specification are all based on the directions of the connecting structure of the reinforced trailer beam and the balance suspension of the utility model when normally working, are not limited to the directions when storing and transporting, only represent relative positional relationship, and do not represent absolute positional relationship.

[0020] As Figures 1 to 3 Commonly shown, a connecting structure of a reinforced trailer beam and a balance suspension, including setting up in the bottom left and right sides of trailer beam 1, left and right two trailer beams 1 are connected with cross beam 2, the through hole is set up on cross beam 2, preferably, the number of through hole is four in the embodiment, in the rest of the implementation, the through hole can also be the rest number;Cross beam 2 is connected with connecting seat 3, connecting seat 3 includes the inclined bracing plate 301 connected with cross beam 2, and the connecting plate 302 fixedly connected at the lower part of inclined bracing plate 301, the connecting plate 302 is connected with balance suspension 4;Connecting plate 302 is vertically arranged with inclined bracing plate 301, and it is more convenient to process.

[0021] The positioning hole 303 is arranged on the inclined support plate 301 at a position corresponding to the through hole, and the number of the positioning hole 303 is the same as that of the through hole on the cross beam 2, and the through hole and the positioning hole 303 are used to preliminarily position and fix the two by using a fastener when the inclined support plate 301 is welded with the cross beam 2, so as to facilitate welding; the connecting plate 302 is provided with a plurality of connecting holes 304 arranged at intervals and used for connecting with the balance suspension 4, and the mounting plate of the balance suspension 4 is also provided with a plurality of connecting holes 304 arranged at positions corresponding to the connecting holes 304, and the connecting plate 302 and the balance suspension 4 are connected through the fastener, which is convenient and fast, and avoids the defects of narrow space, difficulty in welding and easy welding defects.
