Semi-Trailer Suspension Bracket

Technical Field

The utility model relates to a suspension bracket, in particular to a trailer suspension bracket, belonging to the technical field of automotive suspension systems.

Background Technology

Automotive suspension refers to the entire support system composed of springs and other components positioned between the vehicle body and the tires. The functions of the suspension system are to support the vehicle body and absorb road impacts. Different suspension configurations provide drivers with different driving experiences. Although the suspension system appears simple externally, it integrates multiple force interactions and determines the stability, safety, and load-bearing performance of a semi-trailer.

A trailer suspension bracket is one of the important components in a trailer suspension system. Existing trailer suspension brackets are inconvenient for providing improved support performance and durable protection, thereby reducing the safety and durability of the trailer suspension bracket. In addition, their relatively heavy weight increases the vehicle’s dead weight and energy consumption.

Designing a suspension bracket with light weight, good load-bearing capacity, and high safety can improve vehicle safety while reducing vehicle weight and saving fuel.

Summary of the Utility Model

The purpose of the utility model is to provide a trailer suspension bracket to solve the problem in the prior art that existing trailer suspension brackets cannot conveniently provide better support performance and durable protection.

To achieve the above purpose, the utility model provides the following technical solution:

The trailer suspension bracket comprises a first support plate and a second support plate. A bent vertical plate and an inclined vertical plate are fixedly arranged on both sides between the first support plate and the second support plate. A support reinforcing assembly is arranged between the bent vertical plate and the inclined vertical plate. The support reinforcing assembly includes a first reinforcing transverse plate, which is fixedly arranged at the top of one side of the bent vertical plate. Two side edges of the first reinforcing transverse plate are respectively fixedly connected to the tops of the inner sides of the first support plate and the second support plate.

As a preferred technical solution of the utility model, a second reinforcing transverse plate is fixedly arranged between the bent vertical plate and the inclined vertical plate, and a trapezoidal compression-resistant frame is fixedly arranged between the first reinforcing transverse plate and the second reinforcing transverse plate.

As a preferred technical solution of the utility model, an X-shaped reinforcing plate is fixedly arranged inside the trapezoidal compression-resistant frame.

As a preferred technical solution of the utility model, a durable protection assembly is arranged on the other side of the bent vertical plate and one side of the inclined vertical plate. The durable protection assembly includes two anti-corrosion protective layers, which are respectively fixedly arranged on the other side of the bent vertical plate and one side of the inclined vertical plate.

As a preferred technical solution of the utility model, wear-resistant and scratch-resistant protective layers are fixedly sleeved outside the two anti-corrosion protective layers.

As a preferred technical solution of the utility model, the bracket further includes a shock absorber fixing shaft, with both ends of the shock absorber fixing shaft fixedly penetrating through the tops of the outer sides of the first support plate and the second support plate.

As a preferred technical solution of the utility model, leaf spring fixing holes are formed at the bottoms of the outer sides of the first support plate and the second support plate.

Beneficial Effects

Compared with the prior art, the utility model has the following beneficial effects:

The trailer suspension bracket of the utility model uses the first reinforcing transverse plate, trapezoidal compression-resistant frame, X-shaped reinforcing plate, and second reinforcing transverse plate to provide improved support reinforcement between the first support plate and the second support plate. The two anti-corrosion protective layers cooperate with the two wear-resistant and scratch-resistant protective layers to provide external protection for the bent vertical plate and inclined vertical plate respectively, thereby improving support performance and durable protection. As a result, the safety and durability of the trailer suspension bracket are significantly improved.

Detailed Description

The technical solutions in the embodiments of the utility model are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model rather than all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort fall within the protection scope of the utility model.

Referring to Figures 1–4, the utility model provides a trailer suspension bracket including a first support plate 1 and a second support plate 2. A bent vertical plate 4 and an inclined vertical plate 5 are respectively fixedly arranged on both sides between the first support plate 1 and the second support plate 2.

A support reinforcing assembly 3 is arranged between the bent vertical plate 4 and the inclined vertical plate 5. The support reinforcing assembly 3 includes a first reinforcing transverse plate 31, which is fixedly arranged at the top of one side of the bent vertical plate 4. Two side edges of the first reinforcing transverse plate 31 are respectively fixedly connected to the tops of the inner sides of the first support plate 1 and the second support plate 2, facilitating the installation of the trapezoidal compression-resistant frame 32.

Preferably, a second reinforcing transverse plate 34 is fixedly arranged between the bent vertical plate 4 and the inclined vertical plate 5, and a trapezoidal compression-resistant frame 32 is fixedly arranged between the first reinforcing transverse plate 31 and the second reinforcing transverse plate 34 to improve support strength.

Preferably, an X-shaped reinforcing plate 33 is fixedly arranged inside the trapezoidal compression-resistant frame 32 to further improve support performance.

Preferably, a durable protection assembly 6 is arranged on the other side of the bent vertical plate 4 and one side of the inclined vertical plate 5. The durable protection assembly 6 includes two anti-corrosion protective layers 61, which are respectively fixedly arranged on the other side of the bent vertical plate 4 and one side of the inclined vertical plate 5 to provide anti-corrosion protection.

Preferably, wear-resistant and scratch-resistant protective layers 62 are fixedly sleeved outside the two anti-corrosion protective layers 61 to provide wear-resistant and scratch-resistant protection.

The bracket further includes a shock absorber fixing shaft 7, whose two ends fixedly penetrate through the tops of the outer sides of the first support plate 1 and the second support plate 2, facilitating the installation of a shock absorber.
