Technical Field

[0001] This utility model relates to a vibration damper assembly, and more particularly to a reinforced and durable vibration damper assembly. Background Technology

[0002] Existing shock absorber assemblies mainly consist of components such as cover plates, steel sheets, damping springs, and hubs. Two cover plates are riveted to the hub, and square holes in the two cover plates fix the outer side of the damping springs. The steel sheets have square holes that contact and accommodate the damping springs and are connected in the middle. The two rotate relative to each other to compress the damping springs to achieve the damping effect. This structure is prone to wear between the damping springs and steel sheets, and between the damping springs and cover plates, causing the cover plates to crack and the springs to fall off, thus affecting the service life of the shock absorber. Summary of the Invention

[0003] This utility model addresses the technical problem that wear between the damping spring and the steel sheet, and between the damping spring and the cover plate, during the use of existing shock absorber assemblies can easily lead to cracking of the cover plate and detachment of the spring, thus affecting the service life of the shock absorber. It provides a reinforced and durable shock absorber assembly that can effectively reduce wear, prevent breakage and detachment of the damping spring, extend the service life of the shock absorber, and improve the safety of use.

[0004] Therefore, the technical solution of this utility model is a reinforced and durable vibration damper assembly, comprising an upper vibration damping cover, a lower vibration damping cover, and a hub. A liner is mounted on the hub, located between the upper and lower vibration damping covers.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] like Figure 1-5As shown, a reinforced and durable vibration damper assembly includes an upper vibration damping cover 1, a lower vibration damping cover 2, and a hub 4. The upper vibration damping cover 1 and the lower vibration damping cover 2 are welded and fixed together. A liner 3 is mounted on the hub 4, and the liner 3 is located between the upper vibration damping cover 1 and the lower vibration damping cover 2. A vibration damping spring 5 is also provided between the upper vibration damping cover 1 and the lower vibration damping cover 2. A spring pad 6 is provided between the liner 3 and the vibration damping spring 5. The spring pad 6 is made of a plastic wear-resistant material. Limiting pins 7 are provided on the upper damping cover 1 and the lower damping cover 2. Both ends of the limiting pins 7 are provided with stop 7.1. The two ends of the limiting pins 7 are connected to the upper damping cover 1 and the lower damping cover 2 respectively through the stop 7.1. The limiting pins 7 are provided with connecting holes. The side of the lower damping cover 2 away from the liner plate 3 is provided with a transition plate 9. The transition plate 9 is provided with a countersunk hole 13 corresponding to the connecting hole. A connecting bolt 11 is provided in the countersunk hole 13. The connecting bolt 11 passes through the transition plate 9, the lower damping cover 2, the limiting pins 7 and the upper damping cover 1 in sequence, and the end is connected to the locking nut 12 to fix the transition plate 9, the lower damping cover 2, the limiting pins 7 and the upper damping cover 1 together. Dust covers 8 are provided on both sides of the liner plate 3. The dust covers 8 are fixed to the liner plate 3 by rivets 14 and then fixed together with the hub 4. The outer edge of the dust cover 8 contacts the inner edge of the upper damping cover 1 and the lower damping cover 2, so that the upper damping cover 1, the lower damping cover 2 and the dust cover 8 together form a closed cavity to prevent dust and foreign objects from entering the cavity. The dust cover 8 can prevent dust and foreign objects from entering the cavity from the inside, and at the same time prevent foreign objects from falling off due to the breakage of the damping spring 5 and the liner plate 3, which would cause damage to external components. It plays a protective role in the stable operation of the overall structure, can effectively extend the service life and reduce maintenance costs.

[0023] When the vibration damper is working, the active part consists of the transition disc 9, the upper damping cover 1, and the lower damping cover 2, while the driven part consists of the disc hub 4 and the liner 3. Due to the mutual compression and release of the two parts, the damping spring 5 is continuously compressed and stretched. This results in continuous cyclic friction between the damping spring 5 and the liner 3 window, as well as between the damping spring 5 and the upper and lower damping covers 1 and 2, which can easily cause premature wear of the rigid components. This utility model sets a plastic wear-resistant spring pad 6 between the three parts, thereby avoiding wear of the rigid components, preventing wear and cracking of the liner, and breakage and detachment of the damping spring, greatly extending the service life of the vibration damper.

[0024] This application also improves versatility by setting a transition plate 9, which is connected to the vibration damping cover. Different sizes of transition plates 9 can be replaced to make it suitable for different models. The transition plate 9 is provided with countersunk holes 13 for connecting the vibration damping cover, and the head of the connecting bolt 11 is located in the countersunk holes 13, which is both aesthetically pleasing and effectively reduces the space occupied.

[0025] This technical solution has a simple structure and effectively solves problems such as cracking of the damper's liner, wear and breakage of the damping spring. It also effectively avoids the impact of the damping spring and other components falling off on the overall structure, thereby extending the service life of the damper and preventing other components from failing due to damage to the damper.

[0026] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
