Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of balance beams, and in particular to a balance beam for a trailer. Background Art
[0002] The semi-trailer balance beam is a component on the semi-trailer frame used to balance the forces between the axles. The middle part is hinged on the frame, and the two sides are in contact with the edges of two sets of spring plates. As the main force transmission component of the trailer frame, it is prone to wear and cracking when the vehicle is overloaded, which will directly affect the safety performance of the vehicle in serious cases.
[0003] Existing trailer balance beams are mainly composed of simple beam plates and pin sleeves. Although they can provide certain structural support, their durability and load distribution capabilities are still insufficient. The current design is prone to deformation when subjected to high loads and has large friction losses, resulting in a shortened service life. In addition, the lack of effective structural reinforcement measures may lead to stability problems during actual use. Therefore, a new design is urgently needed to enhance the strength, wear resistance and stability of the balance beam to meet higher performance requirements and market demands. Utility Model Content

[0006] Preferably, a wear-resistant cylinder is coaxially arranged on the outer side of the beam plate and the pin sleeve; a bearing is arranged inside the pin sleeve; and both ends of the bearing are located inside the pin sleeve and at a certain distance from both ends of the pin sleeve.
[0007] Preferably, a plurality of reinforcing protrusions are equidistantly arranged, and the cross-section of the reinforcing protrusion is an equilateral triangle structure.
[0008] Preferably, the reinforcing plate, reinforcing protrusions and reinforcing ribs are all made of steel.
[0009] Preferably, the beam plate is provided with fixing holes penetrating the upper and lower beam plates.
[0010] Beneficial effects: Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the arrangement of the reinforcement plate, the strengthening plate, the strengthening protrusions and the strengthening ribs, the strengthening plate greatly increases the strength of the reinforcement plate. And due to the fact that a plurality of strengthening protrusions are densely arranged and the cross-section is triangular, the stability is high and it is not easy to deform.

In an embodiment of the present utility model, a balance beam for a trailer includes two symmetrically arranged beam plates 1, and a support plate 2 is arranged between the two beam plates 1; a pin sleeve 3 penetrating through the two beam plates 1 is provided at the center of the beam plate 1, and a reinforcing plate 6 is installed on the pin sleeve 3; reinforcing plates 7 are fixedly arranged on both sides of the reinforcing plate 6; on one side of each of the two reinforcing plates 7, a reinforcing protrusion 8 is integrally formed; a plurality of reinforcing ribs 9 are equidistantly distributed inside the reinforcing plate 8; a wear-resistant cylinder 4 coaxial with the pin sleeve 3 is arranged on the outer side of the beam plate 1; a bearing 4 is arranged inside the pin sleeve 3; there is a certain distance between the two ends of the bearing 4 inside the pin sleeve 3 and the two ends of the pin sleeve 3, a number of reinforcing protrusions 8 are equidistantly arranged, and the cross section of the reinforcing protrusion 8 is in an equilateral triangle structure. The reinforcing plates 7, the reinforcing protrusions 8 and the reinforcing ribs 9 are all made of steel, and fixing holes 10 penetrating through the upper and lower two beam plates 1 are provided on the beam plate 1.
[0019] Usage process:
[0020] During use, the two symmetrically arranged beam plates 1 are fixed together by the support plate 2. The outer side of the beam plate 1 is coaxial with the pin sleeve 3, which helps to enhance the stability of the structure. The pin sleeve 3 penetrating through the two beam plates 1 at the center plays a role in connecting the beam plates 1. The reinforcing plate 6 is installed on the pin sleeve 3, enhancing the strength of the connecting part. The reinforcing plates 7 are fixedly arranged on both sides of the reinforcing plate 6 to further enhance the strength of the balance beam. A reinforcing protrusion 8 is integrally formed on one side of the reinforcing plate 7. A number of reinforcing protrusions 8 are equidistantly arranged, and the cross section is in an equilateral triangle structure, which helps to improve the bending resistance and stability of the structure. The plurality of reinforcing ribs 9 distributed inside the reinforcing plate 6 enhance the overall strength and rigidity of the reinforcing plate 7. The wear-resistant cylinder 4 coaxial with the pin sleeve 3 is arranged on the outer side of the beam plate 1, and the wear-resistant cylinder is used to reduce wear and extend the service life. The two ends of the bearing 4 are inside the pin sleeve 3, and there is a certain distance between the two ends of the bearing 4 and the two ends of the pin sleeve 3 to reduce friction and wear.
[0021] In the above process, through the settings of the reinforcing plate, the reinforcing plates, the reinforcing protrusions and the reinforcing ribs, the reinforcing plates greatly increase the strength of the reinforcing plate. And due to the dense arrangement of a number of reinforcing protrusions with a triangular cross section, the stability is high and it is not easy to deform. The plurality of reinforcing ribs distributed inside the reinforcing plate enhance the overall strength and rigidity of the reinforcing plate, improving the overall strength and stability of the balance beam; the structure of this application is simple, has strong practicability, and is easy to operate and worthy of promotion.
