Detailed Implementation

[0017] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 and Figure 2As shown, a lightweight structure for the guide arm of an independent suspension is provided, including mounting sleeves 1. There are two mounting sleeves 1. The outer wall of the mounting sleeve 1 on the left is fixedly connected to a pipe beam 2, and the outer wall of the mounting sleeve 1 on the right is fixedly connected to a pipe beam 3. The opposite sides of pipe beam 2 and pipe beam 3 are fixedly connected to a pipe beam 4. The front end of the outer wall of pipe beam 2 is fixedly connected to a square tube 5. The right side of square tube 5 is fixedly connected to the outer wall of pipe beam 3. The left side of the front surface of square tube 5 is fixedly connected to a pipe beam 6. The front end of pipe beam 6 and the front end of pipe beam 3 are fixedly connected to a square tube 7. The material of pipe beam 2, pipe beam 3, pipe beam 4 and pipe beam 6 is QSTE420, and the material of square tube 5 and square tube 7 is Q345B.

[0020] The existing independent suspension guide arm design weighs 39.071 kg, while the lightweight design in this technology weighs 30.21 kg, a reduction of 8.861 kg per component. Using two components per vehicle reduces the overall vehicle weight by 17.722 kg. Furthermore, by replacing the original QSTE600 material with QSTE420 for tube beams 1-2, 2-3, 3-4, and 4-6, the high-grade and unconventional QSTE600 material necessitates custom-made raw materials, leading to procurement challenges. Additionally, the existing independent suspension guide arm design incorporates numerous reinforcing plates, impacting assembly welding quality and production cycle time, thus increasing production costs. This approach reduces the weight of individual components, freeing up space for overall vehicle weight reduction. Moreover, significant improvements are made in component manufacturing processes, materials, and processing cycles, resulting in cost-effectiveness.

[0021] like Figure 1 and Figure 2 As shown, a reinforcing plate 8 is fixedly connected to the upper surface of square tube 5 and the upper surface of square tube 7. A transition bracket 9 is fixedly connected to the upper surface of the reinforcing plate 8. A brake mounting base plate 10 is provided on the left side of the transition bracket 9. The reinforcing plate 8 and the transition bracket 9 are both made of SAPH590 material.

[0022] The brake mounting base plate 10 allows for quick and easy fixing of the guide arm to the brake assembly, while the reinforcing plate 8 and transition bracket 9 ensure a stable connection.

[0023] like Figure 1 and Figure 2 As shown, the front surface of the square tube 2 7 has two shock absorber mounting brackets 11, and the opposite sides of the two shock absorber mounting brackets 11 are fixedly connected to shock absorber mounting sleeves 12.

[0024] The two shock absorber mounting brackets 11 facilitate the connection between the shock absorber assembly and the device.

[0025] like Figure 1 and Figure 2 As shown, a spring mounting bracket 13 is provided on the upper surface of square tube 2 7, and a spring mounting sleeve 14 is provided below the spring mounting bracket 13. The material of the spring mounting bracket 13 is SAPH440.

[0026] The air spring mounting bracket 13 facilitates the connection between the air spring assembly and the device.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
