[0005] The beneficial effect of such an arrangement is that the first ring body edge is folded to form a skirt, which precisely matches the second ring body. A raceway is arranged between the two, and a row of rollers is arranged along the radial direction of the first ring body. This design uses rolling friction instead of sliding friction, which fundamentally avoids the abnormal noise generated by the automobile suspension system during rotation. In the past, sliding friction not only caused increased wear and tear of parts, but also caused annoying noise. This bearing completely solves this problem. The second ring body can closely adhere to the spring disc under high load conditions. At the same time, the rollers act as rotating pairs under the synergistic effect of lubricating grease, greatly reducing the rotation torque of the suspension system. This means that the suspension system can respond more flexibly to road conditions during vehicle operation, improving the comfort of driving and enhancing the stability of vehicle control. In addition, the introduction of the retainer optimizes the design, effectively guiding the orderly operation of the rollers in the raceway, ensuring the stability of the radial position of the rollers, and avoiding the performance degradation of the bearing caused by the displacement of the rollers. The retainer structure plays a key role in ensuring the sealing of the bearing. Good sealing can prevent dust, impurities and other foreign matter from entering the bearing, reducing the wear and tear of parts, and thus greatly extending the service life of the entire bearing. From reducing maintenance costs to improving the overall performance of the automobile

[0007] The beneficial effect of such an arrangement is that this design further optimizes the sealing performance of the bearing, forming a double protection with the retainer structure. When dust and impurities attempt to enter the bearing, the shielding lip can block most of the foreign matter. Even if a small amount of impurities bypass the retainer, the shielding lip can continue to play an intercepting role, keeping foreign matter out, further reducing the risk of part wear and tear, and protecting the stable operation and long service life of the bearing.

[0008] As a further arrangement of the utility model, the end of the second ring body away from the retainer is bent to form a folded edge, and the edge of the shielding lip abuts against the outer circumferential wall of the folded edge.

[0009] The beneficial effect of such an arrangement is that the end of the second ring body away from the retainer is bent to form a folded edge, and the edge of the shielding lip abuts against the outer circumferential wall of the folded edge. This design cleverly improves the stability of the structure installation, preventing displacement and loosening between parts during vehicle operation. At the same time, the close-fitting structure further optimizes the sealing effect, keeping dust, impurities and other foreign matter out. This greatly reduces the wear and tear of parts caused by the invasion of foreign matter, helps the stable operation of the bearing, and prolongs its service life.

[0010] As a further setting of the utility model, the first ring body and the skirt outer peripheral wall are coated with an outer pad, the outer pad is rough, and the shielding lip is integrally arranged with the outer pad.

[0011] The beneficial effect of such a setting is that the friction torque when contacting the spring is greatly improved. When the vehicle is running, the rough surface of the outer pad tightly "grasps" the spring, preventing relative sliding between the two, ensuring the stability of the contact. Avoiding the abnormal stress of the bearing caused by the spring shaking and displacement, the reliability of the automobile suspension system is enhanced in all directions, the system is stably operated, and the driving experience is ensured. In addition, the integrated design also simplifies the assembly process and reduces the production and maintenance cost.

[0012] As a further setting of the utility model, the blocking ring cross section is arranged in an L shape, the blocking ring is attached to the blocking wall, the blocking ring extends a sealing lip towards the second ring body, and the sealing lip end is arranged on the edge of the second ring body.

[0013] The beneficial effect of such a setting is that the blocking ring cross section is designed in an L shape and is tightly attached to the blocking wall, and the sealing lip end is accurately arranged on the edge of the second ring body. The L-shaped design makes the blocking ring and the blocking wall fit more tightly and connect more stably, greatly reducing the risk of falling off. The sealing lip cooperates with the second ring body to form a tight sealing barrier, effectively blocking impurities such as dust and water vapor from entering. Ensure that the bearing can still operate well inside in harsh environments, prolong the service life, and ensure the stability and reliability of the suspension system.
