Technical Field
[0001] The utility model relates to the technical field of vibration-damping materials and equipment, in particular to a high-frequency vibration-damping spring for a suspension system. Background Art
[0002] With the rapid development of new energy vehicles, the automotive industry has ushered in a "second spring." Automotive-related machinery and components are also experiencing new opportunities. For example, high-frequency vibration damping springs used in automotive suspension systems are typically designed to handle high-frequency vibrations, providing effective shock absorption and isolation. With technological advancements and industrial development, breakthroughs in manufacturing technology and materials science have been continuously made in high-frequency vibration damping springs, resulting in superior performance and a wider range of applications. In addition to the automotive industry, high-frequency vibration damping springs are now widely used in numerous fields, including machinery, aerospace, and electronic equipment, becoming crucial components for ensuring stable equipment operation and extending their service life.
[0003] High-frequency vibration damping springs are elastic components that, through their unique structure and material properties, can effectively absorb and reduce high-frequency vibrations. Their operating principle is primarily based on their elastic deformation capacity. When subjected to high-frequency vibrations, the spring undergoes corresponding elastic deformation, thereby absorbing and storing the vibration energy. This deformation process effectively reduces the transmission and diffusion of vibrations, protecting equipment and structures from vibration damage. Due to their excellent vibration control capabilities, high-frequency vibration damping springs can effectively reduce the impact of high-frequency vibrations on equipment and structures. They offer high versatility and flexibility across a wide range of equipment and structures, maintain stable performance over long-term use, and are less susceptible to failure or damage. Consequently, they are widely used in various fields.
[0004] With the widespread use of high-frequency vibration damping springs, some deficiencies that can be improved have gradually become clear: for example, the vibration damping effect of a single high-frequency vibration damping spring in some suspensions is not good enough, and the connection method between such a single high-frequency vibration damping spring and the matching shock absorber or other devices is too simple, which is prone to improper connection. As a result, the high-frequency vibration damping spring has poor vibration damping effect and poor versatility, and cannot be applied to some suspension devices with high fixation requirements.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0024] An embodiment of the utility model discloses a high-frequency vibration-damping spring for a suspension system.
[0025] According to the attached Figure 1-6 As shown, it includes a main spring 1, the pitch of the two ends of the main spring 1 is large, the pitch of the middle part of the main spring 1 is small, the outer diameter of the main spring 1 is large at the bottom and small at the top, and fixed connection components 2 are provided at both ends of the main spring 1. A secondary spring component 3 is provided inside the main spring 1. The fixed connection component 2 includes a lower fixed connection seat 21 and an upper fixed connection seat 22. The upper fixed connection seat 22 and the lower fixed connection seat 21 are fixedly welded to the upper and lower ends of the main spring 1 respectively. The lower fixed connection seat 21 includes a lower spring seat 211 and a clamping member 215. The clamping member 215 is fixedly connected to the bottom end of the lower spring seat 211.

The type-one rubber washer 32 is fixedly connected to the rubber composite spring At the top of 31, the vibration reduction effect of the main spring 1 is increased by setting the pitch and outer diameter of the main spring 1 at different positions, and the auxiliary spring is a rubber composite spring 31. This rubber composite spring 31 combines the advantages of metal springs and rubber springs, has a higher load capacity and large deformation, better shock and noise reduction effects, works smoothly, and can cope with more complex vibration environments. By adopting a dual spring combination of the main spring 1 and the rubber composite spring 31, through the reasonable arrangement of springs with different stiffness and characteristics, effective vibration reduction in a wider frequency range is achieved, especially under high-frequency vibration. The performance is excellent. By setting the upper and lower sets of fixed connection components 2, the two sets of springs are fixed and connected to other components and mechanisms, thereby improving the versatility of the high-frequency vibration reduction spring.
[0026] The lower fixed connecting seat 21 also includes a secondary spring fixing hole 212, a double-threaded rod 213 and a nut 214.
