[0002] Suspension springs are an important component of vehicle suspension. While providing comfort, suspension springs also play a role in supporting the weight of the vehicle.

[0003] The working environment of suspension springs is very harsh. During driving, suspension springs are exposed to high humidity and high salt environment for a long time, and are also hit by stones for a long time, which damages the surface coating. In this way, suspension springs are prone to metal corrosion and stress fracture caused by corrosion, which poses a great safety hazard.

[0004] At present, the industry usually uses double coating technology to slow down the corrosion of suspension springs. However, double coating technology will bring high costs on the one hand, and double coating technology cannot prevent stone impact and cannot eliminate the corrosion risk caused by damage to the surface coating of suspension springs.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the utility model, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0029] Figure 1 The three-dimensional structure of the suspension spring assembly and the suspension shock absorber is shown in figure. Figure 2 The cross-sectional structure of the suspension spring assembly and the suspension shock absorber is shown. Figure 3 The structure of the spring pad of the suspension spring assembly is schematically shown; combined with Figures 1 to 3 As shown, the suspension spring assembly provided by the embodiment of the utility model includes a suspension spring 10 and a spring pad 20 assembled with the suspension spring 10, wherein:

[0030] The spring pad 20 is provided with a support groove 22 for press-fitting the suspension spring 10 . A metal plate 30 is embedded in the surface of the support groove 22 . The metal plate 30 contacts the suspension spring 10 . The metal reducing property of the metal plate 30 is stronger than that of the suspension spring 10 .

[0031] The metal plate 30 is specifically formed into a thin plate structure, which is convenient for embedding into the surface of the support groove 22 and ensures contact with the suspension spring 10 .

[0032] The utility model embeds a metal plate 30 with a metal reducing property stronger than that of the suspension spring 10 in a spring washer 20 assembled with the suspension spring 10, so that the spring washer 20 has an anode sacrificial protection function, thereby having a function of preventing the suspension spring 10 from being corroded, preventing the suspension spring 10 from being oxidized under adverse working conditions such as high humidity, high salinity, and a large amount of stone impact, thereby avoiding the risk of corrosion of the suspension spring 10, greatly improving the life of the suspension spring 10, and enhancing the safety of the vehicle suspension.

[0033] The spring pad 20 is made of rubber or polyurethane, and the end ring of the suspension spring 10 is pressed into the support groove 22 of the spring pad 20. The formed suspension spring assembly is assembled on the shock absorber or control arm of the vehicle. The spring pad 20 is used to isolate the vibration and noise generated during the operation of the suspension spring 10, and plays a role in supporting the suspension spring 10. The spring pad 20 can be assembled at both ends of the suspension spring 10.

[0034] The utility model adds a metal plate 30 with strong metal reducing properties to the original structure of the spring pad 20, and prevents the suspension spring 10 from being corroded during its life cycle through the sacrificial anode protection method. When the metal plate 30 with strong metal reducing properties contacts the suspension spring 10 with weak metal reducing properties, the metal plate 30 forms a protective electrode (anode), which is connected to the protected suspension spring 10 to form a primary battery; at this time, the metal plate 30 with strong reducing properties, as the negative electrode of the primary battery, undergoes an oxidation reaction and is gradually consumed, so as to protect the suspension spring 10 as the positive electrode of the primary battery, so that the suspension spring 10 undergoes a reduction reaction and is prevented from being corroded. In this way, the purpose of preventing the suspension spring 10 from being oxidized is achieved through the method of anode sacrificial protection.

[0035] In some embodiments, the metal plate 30 is embedded in the bottom surface of the support groove 22. The end ring of the suspension spring 10 is pressed into the support groove 22, and the metal plate 30 is embedded in the bottom surface of the support groove 22 to ensure contact with the suspension spring 10, thereby preventing the suspension spring 10 from being oxidized.

[0036] In other embodiments, the metal plate 30 may also be embedded in the side of the support groove 22 as long as it can stably contact the suspension spring 10 .

[0037] In some embodiments, the metal plate 30 is formed into an arc-shaped plate that matches the curvature of the suspension spring 10. In this way, the metal plate 30 supports and half-covers the suspension spring 10, ensuring stable contact with the suspension spring 10.

[0038] In some embodiments, the metal plate 30 is vulcanized and bonded to the surface of the support groove 22. The metal plate 30 and the support groove 22 are stably combined together by vulcanization bonding.

[0039] In other embodiments, the metal plate 30 may be embedded and fixed on the surface of the supporting groove 22 by means of other adhesives.

[0040] In some embodiments, the metal plate 30 forms an integrated smooth surface with the surface of the support groove 22. In this way, on the one hand, the metal plate 30 is prevented from affecting the assembly between the suspension spring 10 and the support groove 22, and on the other hand, the suspension spring 10 is ensured to be in stable contact with the metal plate 30 when it is pressed into the support groove 22.

[0041] In some embodiments, the suspension spring 10 is made of steel, and the metal plate 30 is made of zinc alloy. The main component of steel is iron, and the main component of zinc alloy is zinc. When the suspension spring 10 made of steel and the metal plate 30 made of zinc alloy come into contact with each other, the two form a primary battery, and electrons flow from the metal plate 30 with strong reducing property to the suspension spring 10 with weak reducing property, so that the metal plate 30 is preferentially oxidized, and the suspension spring 10 forms a reduction reaction due to the inflow of electrons, thereby preventing the suspension spring 10 from being oxidized and corroded.

[0042] In other embodiments, the metal plate 30 may also be made of other materials, such as aluminum alloy, magnesium alloy, etc., as long as the metal reducing property of the metal plate 30 is stronger than the metal reducing property of the suspension spring 10, the spring pad 20 has the anodic sacrificial protection function, which can effectively prevent the suspension spring 10 from corrosion.

[0043] In some embodiments, the suspension spring assembly further includes a spring tray 40 assembled with the spring pad 20 ; wherein the spring tray 40 is provided with a mounting groove 44 , the support groove 22 is embedded in the mounting groove 44 , and the mounting groove 44 supports the support groove 22 .

[0044] The spring tray 40 supports the spring washer 20 and the suspension spring 10 , and facilitates the installation of the spring washer 20 and the suspension spring 10 on components such as a shock absorber.

[0045] In some embodiments, the end surface of the support groove 22 is provided with a buckle 220, and the end surface of the installation groove 44 is provided with a clamping groove, and the buckle 220 is buckled with the clamping groove. In this way, a stable and convenient assembly between the spring pad 20 and the spring tray 40 is achieved.

[0046] In other embodiments, the spring washer 20 and the spring tray 40 may also be fastened and connected by fasteners such as bolts.

[0047] In some embodiments, the support slot 22 and the mounting slot are both formed in a U-shape. The U-shaped slot hole can adapt to the curvature of the suspension spring 10 to ensure stable support of the suspension spring 10.

[0048] The utility model also provides a suspension shock absorber. Figures 1 to 3 As shown, the outer wall of the cylinder 50 of the suspension shock absorber is provided with a shoulder 55, and the above-mentioned suspension spring assembly is mounted on the shoulder 55.

[0049] Through the above-mentioned suspension spring assembly, the suspension shock absorber of the utility model can effectively prevent the suspension spring 10 from being oxidized under harsh working conditions such as high humidity, high salinity, and a large amount of stone impact, thereby avoiding the risk of corrosion of the suspension spring 10, greatly improving the life of the suspension spring 10, improving the reliability of the suspension shock absorber, and enhancing the safety of the vehicle suspension.
