Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a high-life shock absorber top rubber. Background Technology

[0002] During vehicle operation, the shock absorber top mount, as a crucial component of the suspension system, plays a vital role in cushioning and damping shocks, providing support and positioning, reducing noise, and protecting related components. It not only effectively absorbs road impacts and improves ride comfort but also ensures precise wheel alignment, enhances vehicle handling stability, reduces vibration and noise, and extends the lifespan of the suspension system. The shock absorber top mount consists of components such as an upper metal cup, a lower metal cup, and vulcanized rubber.

[0003] When installing a conventional top rubber bearing, it is fixed entirely by the annular wall. However, because the annular wall itself is inclined and there is no contact at the bottom, the contact surface mainly contacts the side wall line, which easily leads to misalignment and makes it difficult to install properly. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a high-life shock absorber top adhesive, which mainly solves the problem that conventional shock absorber top adhesives are prone to tilting and are difficult to install properly.

[0006] A high-life shock absorber top adhesive includes a cup body and an adhesive integrally vulcanized and bonded to the outside of the cup body, and also includes...

[0007] An annular groove is provided on the colloid for mounting a planar bearing.

[0008] A boss, located within the annular groove, is used to support the bottom end face of the planar bearing.

[0010] The colloid includes a first wall, a second wall, and a bottom wall connecting the first wall and the second wall, and the first wall, the second wall, and the third wall each have a portion of the skeleton inside.

[0011] The annular groove is located between the first wall and the second wall.

[0012] The bowl body includes an upper bowl body and a lower bowl body, which are connected together by welding.

[0013] The lower end face of the upper bowl body contacts and is welded together with the upper end face of the lower bowl body.

[0014] The boss is located on the inner side of the annular groove.

[0015] The boss has a ring structure.

[0016] The beneficial effects of this utility model are: This utility model provides a high-life shock absorber top rubber, which can also adjust the axial force of the plane bearing from line contact to surface contact, increase the force-bearing area, effectively disperse pressure, improve load-bearing capacity, reduce wear, and optimize the working state of the shock absorber, thereby improving the reliability, durability and driving quality of the automobile suspension system.

[0022] The present invention will be further described below with reference to the accompanying drawings. A high-life shock absorber top rubber includes a cup body 1 and a rubber body 2 integrally vulcanized and connected to the outside of the cup body. It also includes an annular groove 3 disposed on the rubber body for mounting a planar bearing 9; and a boss 31 disposed within the annular groove for supporting the bottom end face of the planar bearing. After the planar bearing is installed, the boss supports the bottom end face of the planar bearing, increasing the contact area. The top rubber directly bears the axial loads from the wheel and shock absorber, such as the impact force during vehicle operation and the longitudinal force during braking. The stepped design expands the stress-bearing surface, allowing the pressure to be distributed more evenly on the top rubber surface, avoiding localized stress concentration and reducing the risk of deformation or damage. When a car is driving at high speed, accelerating / braking rapidly, or off-roading, the suspension system bears greater axial forces. Increasing the stress-bearing area allows the top rubber to withstand higher loads, preventing premature wear or failure and improving reliability. Localized high pressure can easily lead to premature wear or plastic deformation of the top rubber surface, affecting shock absorption performance. The stepped structure optimizes the stress distribution, reduces the pressure per unit area, reduces friction and wear, and extends the life of the top rubber. Uneven force on the top mount may cause the shock absorber to move in an obstructed manner or wear abnormally, affecting the performance of the suspension system. Even force can ensure that the shock absorber works smoothly, maintains stable damping characteristics, improves handling and comfort, and also greatly increases the service life of the top mount.

[0023] In this embodiment, as shown in the figure, a metal skeleton 20 is also provided within the rubber body. This composite structure of vulcanized rubber and metal skeleton significantly enhances the overall structural rigidity, making the top rubber less prone to deformation under high pressure or high-frequency vibration environments. Furthermore, it effectively improves load-bearing capacity, enabling it to withstand greater load impacts under conditions such as rapid acceleration, braking, or off-road driving.

[0024] In this embodiment, as shown in the figure, the colloid includes a first wall 21, a second wall 22, and a bottom wall 23 connecting the first and second walls. The first, second, and third walls each contain a portion of the aforementioned skeleton. This design precisely optimizes stress distribution, preventing early damage caused by localized stress concentration in the rubber. Its high durability design resists dynamic fatigue aging, extending the performance stability of the top adhesive during long-term use. Furthermore, the extended portion improves installation stability, preventing displacement or loosening caused by vibration or impact.

[0025] The vulcanized rubber top mount of the shock absorber incorporates a built-in metal skeleton for support, preventing excessive deformation or creep of the rubber under high pressure or high-frequency vibration. The extended structure disperses stress, preventing localized collapse or torsion and ensuring the top mount maintains a stable geometry during long-term use. The extended portion of the metal skeleton enhances the top mount's compressive and shear resistance, enabling it to withstand greater axial, radial, or torsional loads (such as those from rapid acceleration, braking, or off-road impacts). This design is particularly important in heavy-duty vehicles or high-performance models, preventing top mount failure due to overload. Stainless steel, among other materials, can be used as a material.

[0026] In this embodiment, as shown in the figure, the annular groove is disposed between the first wall and the second wall.

[0027] In this embodiment, as shown in the figure, the bowl body includes an upper bowl body 11 and a lower bowl body 12, which are connected together by welding. Welding is a superior process to riveting in terms of strength, durability, sealing, and long-term reliability, making it particularly suitable for automotive suspension systems with stringent performance requirements. High temperatures allow the metal bowls to completely fuse, forming a molecular-level bond with a connection strength approaching that of the base material itself. The welded area can withstand greater axial and radial loads (such as rapid acceleration, braking, or off-road impacts), reducing safety hazards caused by connection failure.

[0028] Secondly, if the welding process is proper, the weld seam transitions smoothly, avoiding localized stress concentration caused by riveting deformation, thereby improving fatigue life. Welded structures have higher rigidity and can more effectively transmit vibration energy, reducing fatigue damage to the suspension system caused by long-term vibration. For example, in off-road vehicles or high-performance vehicles, welding can maintain long-term stable connection performance, while riveting may gradually loosen over time.

[0029] In this embodiment, as shown in the figure, the lower end face of the upper bowl body is in contact with and welded together with the upper end face of the lower bowl body.

[0030] In this embodiment, as shown in the figure, the boss is disposed on the inner side wall of the annular groove.

[0031] In this embodiment, as shown in the figure, the boss is an annular structure. The annular groove has bosses on its inner annular wall, making the installation of the planar bearing more stable.
