Description

Technical Field

[0001] This utility model relates to the field of suspension control arms, specifically a suspension control arm with high load capacity. Background Technology

[0002] In automotive suspension systems, the suspension arms, as the core force-transmitting components connecting the wheels and the vehicle body, directly affect the vehicle's safety, stability, and durability in terms of load-bearing capacity. As automobiles develop towards larger and heavier vehicles, and as special vehicles and commercial vehicles have an urgent need for high load-bearing performance, the shortcomings of traditional suspension arms in terms of load-bearing capacity are becoming increasingly prominent.

[0003] In existing suspension control arm technology, traditional control arm structures are prone to insufficient structural strength under high loads, and the control arm itself is easily deformed or even damaged, affecting the stability and safety of vehicle driving. At the same time, the shock absorption and cushioning performance of traditional control arms is limited, and it is difficult to effectively absorb vibration energy under complex road conditions, resulting in poor vehicle comfort and accelerated wear and tear on parts. Therefore, a suspension control arm with high load-bearing capacity is proposed to address the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] The following is in conjunction with the appendix Figure 1-5 To further describe this application in detail, embodiments of this application disclose a suspension arm with high load capacity, which is suitable for automotive suspension systems, especially for high-load conditions (such as commercial vehicles and heavy-duty vehicles), and can improve driving stability, safety and component lifespan.

[0029] Reference Figures 1 to 5 A suspension swing arm with high load capacity includes a swing arm body assembly 1 and a first reinforcing rib 2.

[0030] The swing arm body assembly 1 includes a swing arm 101. A through groove 102 is provided on the upper part of the swing arm 101, and a groove 103 is provided at the end of the swing arm 101. A pad 104 is fixedly connected to the end face of the swing arm 101. The through groove 102 passes through the swing arm 101. There are four pads 104, which are distributed at the ports of two grooves 103. A gap is left between the pad 104 and the connecting sleeve 5, and the pad 104 is a rubber shock-absorbing pad.

[0031] Preferably, the swing arm 101 is made of aluminum alloy casting.

[0032] The pad 104 at the end of the groove 103 has a gap with the connecting sleeve 5. When the swing arm 101 vibrates at high frequency, the pad 104 absorbs the residual shock through elastic deformation, avoiding direct rigid collision between the connecting sleeve 5 and the swing arm body assembly 1, and reducing the amplitude of vibration transmitted to the frame.

[0033] The first reinforcing rib 2 is fixedly connected to the through groove 102. Preferably, the first reinforcing rib 2 is fixed to the swing arm 101 by TIG welding.

[0034] The cross structure of the first reinforcing rib 2 decomposes the concentrated load into components along the x and y axes, which are uniformly transmitted through the swing arm body. Compared with the traditional single-rib structure, the stress concentration factor is reduced.

[0035] A second reinforcing rib 3 is fixedly connected inside the groove 103. A hydraulic damping rod 4 is fixedly connected at the center of the inner wall of the groove 103. There are two hydraulic damping rods 4, which are distributed at both ends of the swing arm 101. A connecting sleeve 5 is fixedly connected to the end of the hydraulic damping rod 4. There are two connecting sleeves 5, which are distributed at both ends of the swing arm 101. There are multiple first reinforcing ribs 2, which are distributed in a crisscross pattern on the inner wall of the through groove 102. The second reinforcing rib 3 is generally X-shaped. There are four second reinforcing ribs 3, which are divided into groups of two. Each group of X-shaped second reinforcing ribs 3 forms two triangular support units. Two hydraulic damping rods 4 are distributed between each group of second reinforcing ribs 3. When the swing arm 101 is impacted, the piston inside the hydraulic damping rod 4 compresses the hydraulic oil through the throttle hole, generating a damping force opposite to the direction of movement.

[0036] During installation, first fix the hydraulic damping rod 4 to the inner wall of the recess 103 with bolts, then fix the connecting sleeve 5 to the end of the hydraulic damping rod 4, and finally attach the rubber pad 104 to the groove port to ensure uniform gap.

[0037] The swing arm 101 has a through groove 102, and the first reinforcing ribs 2 distributed in the groove form a grid-like support structure, which distributes the load borne by the swing arm to the entire swing arm body through the cross ribs, reducing local stress concentration.

[0038] An "X"-shaped second reinforcing rib 3 is provided in the groove 103 at the end of the swing arm 101. Two second reinforcing ribs 3 in each group intersect diagonally to form a stable triangular support structure, which enhances the torsional stiffness of the groove 103 area and effectively resists deformation under load.

[0039] When the swing arm 101 is subjected to a load such as road impact, the hydraulic damping rods 4 at both ends absorb vibration energy through the flow of internal hydraulic oil, converting kinetic energy into heat energy and releasing it, thus mitigating the instantaneous impact of the load on the swing arm 101. The connecting sleeves 5 at the ends of the hydraulic damping rods 4 are used to fix the swing arm 101 to the frame or wheel components, ensuring the stability of the load transmission path.

[0040] Working principle: The external load is transmitted to the hydraulic damping rod 4 through the connecting sleeve 5. The hydraulic damping rod first attenuates the vibration through the damping effect. Then, the load is distributed to the groove 103 area through the second reinforcing rib 3, and then transmitted to the entire swing arm 101 through the cross network of the first reinforcing rib 2. During this process, the rubber pad 104 buffers the impact of the connection part in real time, forming a triple shock absorption mechanism of "damping attenuation - structural dispersion - elastic buffering". At the same time, the reinforcing rib structure ensures that the swing arm maintains rigidity under high load.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
