Description

Technical Field

[0001] This utility model relates to the field of sealing sleeve technology, and in particular to a dustproof and waterproof sealing sleeve for a motorcycle shock absorber with a silicone coating. Background Technology

[0002] As a core component ensuring riding stability and safety, motorcycle shock absorbers are exposed to complex outdoor environments for extended periods. They are susceptible to corrosion from impurities such as dust, mud, and rainwater, leading to wear of internal seals and contamination of hydraulic oil. This can result in reduced shock absorption performance, abnormal noises, and even component failure. Therefore, protective measures are necessary through sealing sleeves.

[0003] Most existing motorcycle shock absorber sealing sleeves are made of a single rubber material. Although they have basic elasticity and sealing ability, the rubber substrate has limited weather resistance and water resistance. With long-term use, they are prone to aging and cracking due to ultraviolet radiation and rain immersion, and the protective effect will significantly decrease over time. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a dustproof and waterproof sealing sleeve for motorcycle shock absorbers with a silicone coating.

[0005] This utility model proposes a dustproof and waterproof sealing sleeve for a motorcycle shock absorber with a silicone coating, comprising a first elastic part and a second elastic part integrally connected to both ends of the first elastic part. Both the first elastic part and the second elastic part are made of rubber, and the hardness of the first elastic part is greater than that of the second elastic part. The outer surfaces of the first elastic part and the second elastic part are coated with a silicone coating to protect them.

[0006] Furthermore, the top of the second elastic part is integrally connected to the first flange, and the bottom of the second elastic part is integrally connected to the lower flange, so as to install the sealing sleeve on the motorcycle shock absorber.

[0007] Furthermore, the diameter of the first flange is larger than that of the lower flange to accommodate the flange of the motorcycle shock absorber.

[0008] Furthermore, the bottom of the first flange is provided with several air holes to allow for air exhaust and intake when the first elastic part and the second elastic part contract and expand.

[0009] Furthermore, the first elastic part is configured as a straight cylinder, and the second elastic part is configured as an umbrella skirt.

[0010] Furthermore, the outer surface of the first elastic part is integrally formed with several reinforcing ribs at equal intervals to improve the strength of the first elastic part.

[0011] Furthermore, a plurality of crumple grooves are provided at equal intervals on the inner surface of the first elastic part, and the crumple grooves correspond to the reinforcing ribs.

[0012] The beneficial effects of this utility model are as follows: By coating the outer surfaces of the first and second elastic parts with a silicone coating designed with different hardness, the excellent weather resistance, waterproofness, and wear resistance of the silicone coating can effectively block the erosion of dust, rainwater, and other impurities, prevent the rubber substrate from aging and cracking, and extend the overall service life of the sealing sleeve. Furthermore, by combining the structural compatibility of the straight cylindrical first elastic part and the umbrella-shaped second elastic part, the size matching design of the flange, the air pressure balance function of the vent, and the synergistic effect of the reinforcing ribs and the collapse groove, it can be ensured that the sealing sleeve maintains a stable dustproof and waterproof sealing effect while smoothly expanding and contracting with the shock absorber, thus comprehensively guaranteeing the long-term stable operation of the motorcycle shock absorber.

[0018] Reference Figure 1-4 This utility model proposes a silicone-coated dustproof and waterproof sealing sleeve for motorcycle shock absorbers, comprising a first elastic part 1 and a second elastic part 4, which are integrally formed by injection molding to ensure the sealing and stability of the overall structure. Both are made of rubber as the base material, which has excellent elasticity and deformation capacity. It can synchronously contract and expand with the extension and contraction of the motorcycle shock absorber 6, avoiding sealing failure or component damage caused by rigid materials that cannot deform. The hardness of the first elastic part 1 is greater than that of the second elastic part 4. This difference in hardness is based on the functional division of the two parts. The first elastic part 1 needs to bear the main structural support role to prevent the sealing sleeve from being excessively deformed due to external pressure or vibration during long-term use. Therefore, it needs higher hardness to ensure structural stability. The second elastic part 4 needs more flexible deformation capacity to adapt to the angular deviation or slight displacement between the shock absorber and the mounting component, ensuring the sealing fit at the connection and avoiding gaps.

[0019] The outer surfaces of the first elastic part 1 and the second elastic part 4 are completely coated with a silicone coating 5. The silicone material has excellent weather resistance, corrosion resistance and water resistance. On the one hand, it can effectively block external dust, mud, rainwater and other impurities from directly contacting the rubber substrate, preventing the rubber from aging and cracking due to wear from impurities or soaking in rainwater. On the other hand, the silicone coating 5 can also reduce the erosion of rubber by environmental factors such as ultraviolet rays and high and low temperatures, and extend the overall service life of the sealing sleeve.

[0020] To achieve stable assembly of the sealing sleeve and the motorcycle shock absorber 6, a first flange 2 is integrally connected to the top of the second elastic part 4 at the top, and a lower flange 3 is integrally connected to the bottom of the second elastic part 4 at the bottom. The two serve as connecting carriers, and the sealing sleeve can be firmly installed in the corresponding assembly position of the shock absorber by fasteners such as bolts. At the same time, the diameter of the first flange 2 is larger than the diameter of the lower flange 3. This size difference design is to adapt to the flange specifications of different positions of the motorcycle shock absorber 6. Generally, the flange size of the upper part of the shock absorber connected to the frame is larger, and the flange size of the lower part connected to the wheel assembly is smaller. By matching flanges of different diameters, the assembly accuracy of the sealing sleeve and the shock absorber can be ensured, and the sealing performance of the connection can be further improved.

[0021] Several air holes 21 are evenly distributed around the bottom of the first flange 2. As the sealing sleeve expands and contracts with the shock absorber, its internal space will change in volume. When the shock absorber is compressed and the sealing sleeve contracts, the internal air needs to be discharged quickly to avoid the sealing sleeve from bulging and deforming due to excessive air pressure. When the shock absorber extends and the sealing sleeve returns to its original position, air needs to be drawn in to fill the space to avoid the sealing sleeve from collapsing due to negative pressure. The setting of air holes 21 solves this problem precisely, realizes the air pressure balance between the inside and outside of the sealing sleeve, ensures its expansion and contraction, and avoids the impact of air pressure changes on sealing performance.

[0022] The first elastic part 1 is set in a straight cylinder shape, which can better fit the cylindrical body of the motorcycle shock absorber 6, ensuring uniform coverage. At the same time, the straight cylinder structure is more stable under force when it expands and contracts, and is less prone to local wrinkles or damage. The second elastic part 4 is set in an umbrella skirt shape. The umbrella skirt structure has a larger deformation margin and can tightly wrap the connection between the shock absorber and the flange, effectively preventing impurities from entering from the connection gap. At the same time, its inclined skirt design can also guide rainwater to flow downwards, further improving the waterproof effect.

[0023] To enhance the structural strength of the first elastic part 1, a number of reinforcing ribs 11 are integrally formed at equal intervals on its outer surface. The reinforcing ribs 11 are made of the same rubber material as the first elastic part 1. The integral molding design ensures a firm connection and prevents the problem of falling off. When the sealing sleeve is subjected to external pressure or long-term vibration, the reinforcing ribs 11 can disperse the stress, reduce the degree of deformation of the first elastic part 1, avoid rubber fatigue damage caused by repeated deformation, and extend its service life.

[0024] Correspondingly, a plurality of crumple grooves 12 are provided at equal intervals on the inner surface of the first elastic part 1, and the crumple grooves 12 correspond one-to-one with the reinforcing ribs 11. The core function of this design is to balance the influence of the reinforcing ribs 11 on the elasticity. Although the reinforcing ribs 11 improve the strength, they may reduce the deformation flexibility of the first elastic part 1. The crumple grooves 12 can provide deformation space when the sealing sleeve contracts, so that the first elastic part 1 can still contract smoothly. At the same time, the crumple grooves 12 on the inner surface can also reduce the contact area between the sealing sleeve and the surface of the shock absorber, reduce the frictional resistance between the two, avoid wear on the surface of the shock absorber or damage to the sealing sleeve caused by friction, and ensure the stability of the coordinated work of the sealing sleeve and the shock absorber.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
