[0002] In the field of heavy-duty highway transportation, trailer suspension systems are crucial for ensuring smooth driving and cargo safety. Due to their variable stiffness characteristics and height-adjustable advantages, air springs have gradually replaced leaf springs as the core component of modern trailer suspensions. With the improvement of logistics efficiency and vehicle speed, especially in curves and lane changes, higher requirements are placed on the anti-roll stability of the suspension system while maintaining comfort, which has driven the continuous development of integrated devices that combine load-bearing, shock absorption and anti-roll functions.

[0003] Application number 201610953.4 proposes an interconnected air spring suspension system for automobiles that achieves torsion suppression, pitch prevention, and roll prevention. The system includes air springs and shock absorbers. The air springs are mounted on the upper side of the vehicle's wheels, with two air springs on the upper side of each wheel. Two air springs on different wheels at the same end are connected via a first conduit. The remaining air springs on different wheels at the same end are connected to the remaining air springs on different wheels at the other end via second conduits. The shock absorbers are connected to both the first and second conduits. This system provides stable vehicle operation, even force distribution on the vehicle body, wide applicability, and control over the overall vehicle height. It offers comprehensive and improved pitch and roll prevention, enhancing vehicle comfort and safety.

[0004] While the aforementioned documents address issues such as smooth vehicle operation, even force distribution on the vehicle body, wide applicability, controllable overall vehicle height, and improved anti-pitch and anti-roll functions, thereby enhancing vehicle comfort and safety, they also have the following drawbacks: trailer air spring installation structures are mostly of fixed dimensions, connection parameters are not adjustable, and they can only match a single type of air spring. Therefore, a trailer air spring device with anti-roll function has emerged. Utility Model Content

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Example Reference Figures 1-4 This embodiment of the present invention provides a trailer air spring device with anti-tilt function, comprising, The air spring body 101 includes a top plate 102 fixedly installed on the surface of the air spring body 101, a bottom plate 103 fixedly connected to the bottom of the air spring body 101, a connecting component 104 disposed on the surface of the top plate 102, an adjusting component 105 threadedly connected to the surface of the bottom plate 103, and a fixing component 106 slidably connected to the bottom of the adjusting component 105. The connecting assembly 104 includes a first bolt 104a welded to the surface of the top plate 102, a U-shaped plate 104b sleeved on the surface of the first bolt 104a, a nut 104c threadedly connected to the surface of the first bolt 104a, and a connector 104d rotatably connected to the side wall of the U-shaped plate 104b.

[0020] Specifically, the air spring body 101 is connected to the upper structure of the trailer via the top plate 102 and the connecting assembly 104. The connecting piece 104d is connected to the trailer components. The U-shaped plate 104b is fixed to the top plate 102 by the first bolt 104a and the nut 104c. The connecting piece 104d can rotate relative to the U-shaped plate 104b. When the trailer is driving normally or experiencing minor vibrations, the elastic deformation of the air spring absorbs the impact and protects the connecting components.

[0021] Furthermore, the adjustment assembly 105 includes a second bolt 105a inserted into the surface of the base plate 103, an adjustment plate 105b disposed at the bottom of the base plate 103, a rotating shaft 105c inserted into the side wall of the adjustment plate 105b, and a sliding plate 105d rotatably connected to the surface of the rotating shaft 105c.

[0022] When the trailer tilts to one side, the air springs on both sides are subjected to uneven force. The adjusting plate 105b rotates around the pivot 105c to adapt to the angle change caused by the height difference between the two sides.

[0023] Preferably, the fixing component 106 includes a slide rail 106a slidably connected to both ends of the slide plate 105d, a mounting plate 106b fixedly installed at the bottom of the slide rail 106a, a threaded hole 106c opened in the side wall of the slide rail 106a, and a third bolt 106d threadedly connected to the side wall of the slide rail 106a.

[0024] Tighten the third bolt 106d to insert it into the insertion hole on the side wall of the slide plate 105d, so that different models of air springs can be installed.

[0025] It should be noted that the U-shaped plate 104b is set on the surface of the top plate 102, the nut 104c is snapped onto the surface of the U-shaped plate 104b, and the side wall of the slide plate 105d is provided with an insertion hole adapted to the installation of the third bolt 106d, which is inserted into the side wall of the slide plate 105d.

[0026] In use, the air spring body 101 is connected to the upper structure of the trailer via the top plate 102 and the connecting assembly 104. The connecting piece 104d is connected to the trailer components. The U-shaped plate 104b is fixed to the top plate 102 by the first bolt 104a and the nut 104c. The connecting piece 104d can rotate relative to the U-shaped plate 104b. When the trailer is driving normally or experiencing slight vibrations, the elastic deformation of the air spring absorbs the impact and protects the connecting components. When the trailer tilts, the air springs on both sides are subjected to uneven forces. The adjusting plate 105b rotates around the pivot 105c to adapt to the angle change caused by the height difference between the two sides. The third bolt 106d is tightened so that it is inserted into the insertion hole on the side wall of the sliding plate 105d, so that different models of air springs can be installed.

[0027] In summary, the connection component 104 reduces stress concentration in the rigid connection during tilting or vibration, thus reducing wear on the air spring and surrounding components; the adjustment component 105 allows the air spring to adapt to angle changes caused by height differences on both sides; and the fixing component 106 enables the installation of different models of air springs. The device is easy and efficient to operate, effectively solving the problem that trailers can only be matched with a single model of air spring.
