Description

Technical Field

[0001] This utility model relates to the field of automotive equipment technology, and in particular to an air suspension C-beam. Background Technology

[0002] Air suspension systems originated in the mid-19th century, initially used primarily for vibration isolation in machinery. By the 1950s, they were widely adopted in trucks, buses, cars, and railway vehicles. Currently, the usage rate of air suspension systems in high-end buses both domestically and internationally reaches as high as 98%, and in heavy-duty trucks, it exceeds 80%. In some specialized vehicles, air suspension systems have become standard equipment.

[0003] The C-beam in a car's air suspension system is a crucial load-bearing component. Its primary function is to support the weight of the entire vehicle body and provide excellent shock absorption. During driving, the C-beam effectively absorbs impacts and vibrations from the road surface, ensuring a smooth and comfortable ride. Furthermore, the C-beam's structural design allows it to remain stable even under significant forces, reducing its likelihood of breakage and greatly improving vehicle safety. However, existing air suspension C-beams have certain structural design flaws. The connection between the air suspension C-beam and the vehicle body is typically achieved using bolts that penetrate the beam. This significantly compromises the internal structural stability of the C-beam, posing a considerable risk to the car's air suspension system. Utility Model Content

[0004] Therefore, this utility model provides an air suspension C-beam to overcome the problem in the prior art where drilling holes in the air suspension C-beam when connecting the vehicle body and the air suspension C-beam damages the structural stability of the C-beam.

[0005] To achieve the above objectives, this utility model provides an air-suspended C-beam, comprising:

[0006] The C-shaped beam includes a load-bearing section and a vibration-damping section. The load-bearing section is the straight section of the beam, and the vibration-damping section consists of two curved sections that bend from both ends of the straight section to the two ends of the beam.

[0007] The connecting assembly includes an upper pressure plate, a lower pressure plate, and several support sleeves. The upper pressure plate and the lower pressure plate are respectively disposed on the top and bottom surfaces of the load area of ​​the C-shaped beam. Several mounting holes are provided on the upper pressure plate and the lower pressure plate. Each of the support sleeves is located between the upper pressure plate and the lower pressure plate and is coaxially disposed with the corresponding mounting hole.

[0008] Furthermore, the upper end face of the load section of the C-shaped beam is provided with several positioning pins, and the upper pressure plate is provided with several positioning holes, each positioning hole cooperating with the corresponding positioning pin.

[0009] Furthermore, the load section of the C-shaped beam is provided with a lower thrust rod connecting seat.

[0010] Furthermore, a gasket is provided between the end of the lower thrust rod connecting seat and the C-shaped beam.

[0011] Furthermore, a front reinforcing beam support is provided on the bottom end face of the load section of the C-shaped beam near the connecting assembly.

[0012] Furthermore, a rear reinforcing beam support is provided on the bottom surface of the load area of ​​the C-shaped beam, away from the front reinforcing beam support.

[0013] Furthermore, a U-shaped bracket is provided on the top surface of the load area of ​​the C-shaped beam near the upper pressure plate.

[0014] Furthermore, the bottom surface of the vibration damping zone of the C-shaped beam is connected to an air spring tray via several tray supports.

[0015] Furthermore, the end of the vibration damping zone of the C-shaped beam is connected to a vibration damper bracket via several tray brackets.

[0016] Compared to existing technologies, the advantages of this invention are as follows: The positioning design of the upper and lower pressure plates, through the cooperation of positioning pins and positioning holes, ensures the precise positioning of the upper pressure plate and the load section of the C-shaped beam, avoiding stress concentration or connection failure caused by installation errors. The coaxial arrangement of the support sleeve and the mounting hole can evenly distribute the pressure during bolt connection, prevent excessive local stress, and improve the reliability and durability of the connection components.

[0017] Furthermore, the lower thrust rod connector extends through the C-beam, facilitating the installation and removal of the lower thrust rod. This through-type design also enhances the connector's torsional resistance, improving vehicle handling stability. A gasket at the end of the lower thrust rod connector absorbs minor vibrations and displacements between the connector and the C-beam, reducing metal fatigue and extending component lifespan.

[0018] Furthermore, by installing front and rear reinforcing beam supports at the bottom end of the load section, the local stiffness of the C-shaped beam can be significantly improved, especially under large loads, preventing beam deformation or fracture. The front reinforcing beam support is close to the connecting components, while the rear reinforcing beam support is far away from the front reinforcing beam support, forming a reasonable support layout and further improving the overall structural stability.

[0019] Furthermore, installing a U-shaped bracket at the top surface of the load section enhances the lateral stability of the C-beam, especially when the vehicle is turning or subjected to lateral forces, preventing lateral displacement of the beam. The U-shaped bracket, located near the upper pressure plate, works synergistically with the connecting components to further improve the overall structure's resistance to tilting.

[0020] Furthermore, by connecting the air spring tray to the vibration damper bracket via a tray support, an integrated vibration damping module is formed, which can more efficiently absorb and disperse vibration energy. The design of multiple tray supports can evenly distribute the force on the air spring tray, prevent excessive local stress, and improve the reliability and durability of the vibration damping system.

[0021] In summary, this C-beam air suspension design, through the coordinated design of the load-bearing and damping sections, optimization of connecting components, reinforcement of the beam and U-shaped supports, and integrated design of the damping section, achieves a comprehensive improvement in load-bearing capacity, damping performance, installation accuracy, fatigue resistance, and lateral stability. Simultaneously, the lightweight design reduces the overall vehicle weight, improving fuel economy and handling performance. The overall design structure is reasonable and highly reliable, making it suitable for various vehicles requiring high-performance air suspension systems. Attached Figure Description
