[0002] Patent publication number CN213322547U discloses an integral semi-trailer leaf spring bracket, which eliminates welding connections through an integral design, reduces the complexity of the manufacturing process, and improves the overall strength and reliability of the components. It is connected to the frame using rivets instead of welding, which improves the consistency and reliability of the connection, and reduces deformation and dimensional errors in the manufacturing process. However, during the use of the leaf spring bracket, since the leaf spring and the leaf spring bracket are connected by a leaf spring pin, during long-term use, the mounting holes on the two leaf spring mounting platforms on the leaf spring bracket that are connected to the pin are prone to breakage. In this way, since it is an integral semi-trailer leaf spring bracket, the entire semi-trailer leaf spring bracket needs to be replaced, but the semi-trailer leaf spring bracket is heavy and not easy to replace. Therefore, it is necessary to design a split semi-trailer leaf spring bracket for easy disassembly and replacement. Utility Model Content

In this way, by decomposing the leaf spring bracket into two detachable first connecting parts 1 and second connecting parts 2, when the first connecting part 1 or the second connecting part 2 is damaged, it does not need to be replaced as a whole, and only the damaged first connecting part 1 or the second connecting part 2 needs to be replaced, which is convenient for disassembly and assembly.

[0023] like Figure 1-2 As shown, the first connecting part 1 includes: a connecting plate 6 and a first n-shaped plate 5, the first connecting plate 6 and the first n-shaped plate 5 are manufactured in an integrally formed manner, the connecting plate 6 and the top plate of the first n-shaped plate 5 are perpendicular to each other and fixedly connected, the connecting plate 6 and one side of the first n-shaped plate 5 are located on the same plane, the connecting plate 6 is provided with two through holes 9, and bolts pass through the through holes 9 to connect with the frame 13, so that the first connecting part 1 can be disassembled by bolts, which is convenient for installation and maintenance, the first n-shaped plate 5 is provided with a first connecting hole 7 on the side plate, the second connecting part 2 is located between the two side plates of the first n-shaped plate 5, the pin 3 passes through the first connecting hole 7 and the second connecting part 2 for rotational connection, which is convenient for disassembly of the second connecting part 2.

[0024] like Figure 2 As shown, a reinforcing rib 8 is further provided between the connecting plate 6 and the first n-shaped plate 5, and the connection between the connecting plate 6 and the first n-shaped plate 5 is reinforced by the reinforcing rib 8. The reinforcing rib 8 is a right-angled triangle, and one right-angled side of the right-angled triangle is fixedly connected to the connecting plate 6, and the right-angled side of the right-angled triangle adjacent to the connecting plate 6 is fixedly connected to the first n-shaped plate 5, and the reinforcing rib 8 is located at the center of the connecting plate 6.

[0025] like Figure 3 As shown, the second connection part 2 includes a second n-shaped plate 10, the height of the second n-shaped plate 10 is greater than the height of the first n-shaped plate 5, the side plate of the second n-shaped plate 10 is provided with a second connection hole 11 at one end close to the first n-shaped plate 5, and the side plate of the second n-shaped plate 10 is provided with a third connection hole 12 at one end away from the first n-shaped plate 5, the pin 3 passes through the first connection hole 7 and the second connection hole 11 to connect the first n-shaped plate 5 and the second n-shaped plate 10, and the two ends of the pin 3 are tightened by nuts 4, so that the first n-shaped plate 5 and the second n-shaped plate 10 can be detachably connected, if there is a problem with the second n-shaped plate 10, the second n-shaped plate 10 can be replaced, which is convenient for replacement. The pin 3 passes through the third connection hole 12 and the through holes 9 at both ends of the leaf spring 14, so that the leaf spring 14 and the second n-shaped plate 10 can be connected, so that the second n-shaped plate 10 can be easily disassembled.

[0026] like Figure 1 As shown, the side plate length of the second n-shaped plate 10 is greater than the side plate length of the first n-shaped plate 5 , and the second connecting hole 11 of the second n-shaped plate 10 is located outside the first n-shaped plate 5 , which facilitates the connection between the second n-shaped plate 10 and the leaf spring 14 .
