Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to a suspension bearing for automotive shock absorbers that prevents jamming. Background Technology

[0002] Automotive suspension bearings are one of the key components of the automotive suspension system, playing a vital role in ensuring the vehicle's driving stability, handling, and ride comfort.

[0003] When using existing automotive shock absorber suspension bearings, the plastic upper and lower covers may collide with each other during rotation, causing jamming and reducing the smoothness of bearing rotation. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a suspension bearing for automotive shock absorbers that prevents jamming.

[0005] The purpose of this utility model can be achieved through the following technical solution: a suspension bearing for an anti-jamming automotive shock absorber, comprising a plastic upper cover and a plastic lower cover, wherein an upper placement groove is provided on the outer side of the top of the plastic upper cover, an upper anti-hook ring is connected to the top of the inner wall of the upper placement groove, a lower placement groove is provided on the outer side of the top of the plastic lower cover, the plastic upper cover is placed upside down on top of the plastic lower cover, a bearing ring is placed between the upper placement groove and the lower placement groove, a lower anti-hook block is connected to the top of the inner wall of the plastic lower cover for use with the upper anti-hook ring, and a sealing ring is fitted between the outer side of the inner wall of the upper placement groove and the top of the outer side of the plastic lower cover.

[0006] This anti-jamming suspension bearing for automotive shock absorbers uses an upper anti-hook ring and a lower anti-hook block. The plastic upper cover is inverted and placed on top of the plastic lower cover. The upper and lower anti-hook rings are connected by anti-hooks. Furthermore, the upper anti-hook ring is designed as a full-circle anti-hook, and the lower anti-hook block has a six-part structure. When the plastic upper and lower covers rotate relative to each other, the anti-hook collisions prevent jamming, making the bearing rotate more smoothly, reducing noise and making it less likely to be pulled out.

[0007] In the aforementioned anti-jamming suspension bearing for automotive shock absorbers, the number of lower anti-hook blocks is six, and the six lower anti-hook blocks are arranged in a circular array with the plastic lower cover as the center. Through the cooperation of the lower anti-hook blocks and the upper anti-hook ring, an anti-hook connection can be established between the plastic upper cover and the plastic lower cover.

[0008] In the aforementioned anti-jamming suspension bearing for automotive shock absorbers, a positioning disc is fitted onto the bottom of the outer plastic lower cover. Several positioning screws are connected to the bottom of the positioning disc, and positioning nuts are threaded onto the bottom of each positioning screw. These positioning screws facilitate the subsequent installation of the elastic washer and the external mounting platform.

[0009] In the aforementioned anti-jamming suspension bearing for automotive shock absorbers, an elastic washer and an external mounting platform are sequentially fitted from top to bottom around the locating screw, located between the locating disc and the locating nut. The elastic washer provides shock-absorbing protection for the suspension bearing, extending its service life.

[0010] In the aforementioned anti-jamming suspension bearing for automotive shock absorbers, the elastic washer comprises a metal washer, the metal washer being covered by a rubber washer. The metal washer enhances the strength of the elastic washer.

[0011] In the aforementioned anti-jamming suspension bearing for automotive shock absorbers, the sealing ring includes a metal cage, and a rubber ring is wrapped around the outside of the metal cage. The metal cage increases the strength of the sealing ring.

[0012] Compared with existing technologies, this anti-jamming suspension bearing for automotive shock absorbers uses the cooperation of an upper anti-hook ring and a lower anti-hook block. The plastic upper cover is inverted on top of the plastic lower cover. The cooperation of the upper anti-hook ring and the lower anti-hook block makes the plastic upper cover and plastic lower cover connected by anti-hook. Furthermore, the anti-hook design of the upper anti-hook ring is a full circle anti-hook, and the lower anti-hook block has a six-part structure. When the plastic upper cover and plastic lower cover rotate relative to each other, the jamming caused by the anti-hook collision is avoided, making the bearing rotate more smoothly, reducing noise and making it less likely to be pulled out.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this anti-jamming suspension bearing for automotive shock absorbers includes a plastic upper cover 1 and a plastic lower cover 5. The outer side of the top of the plastic upper cover 1 has an upper placement groove 3. The top of the inner wall of the upper placement groove 3 is connected to an upper anti-hook ring 2. The outer side of the top of the plastic lower cover 5 has a lower placement groove 4. The plastic upper cover 1 is placed upside down on top of the plastic lower cover 5. A bearing ring 7 is placed between the upper placement groove 3 and the lower placement groove 4. The top of the inner wall of the plastic lower cover 5 is connected to a lower anti-hook block 6 that works with the upper anti-hook ring 2. A sealing ring 9 is fitted between the outer side of the inner wall of the upper placement groove 3 and the top of the outer side of the plastic lower cover 5.

[0024] In actual manufacturing, there are six lower reverse hook blocks 6, and the six lower reverse hook blocks 6 are arranged in a circular array with the plastic lower cover 5 as the center.

[0025] In use, the plastic top cover 1 is placed upside down on top of the plastic bottom cover 5. The upper reverse hook ring 2 and the lower reverse hook block 6 work together to connect the plastic top cover 1 and the plastic bottom cover 5 with reverse hooks. Furthermore, the upper reverse hook ring 2 is designed as a full circle of reverse hooks, and the lower reverse hook block 6 is a six-part structure. When the plastic top cover 1 and the plastic bottom cover 5 rotate relative to each other, the reverse hook collisions are avoided, making the bearing rotate more smoothly, reducing noise and making it easier to pull out. Example 2

[0026] like Figure 6 , Figure 7 and Figure 8As shown, a positioning disc 8 is fitted on the bottom of the plastic lower cover 5. Several positioning screws 12 are connected to the bottom of the positioning disc 8, and positioning nuts 13 are threaded on the bottom of the positioning screws 12.

[0027] In actual manufacturing, an elastic washer 10 and an external mounting platform 11 are sequentially fitted from top to bottom on the outside of the positioning screw 12 and between the positioning disc 8 and the positioning nut 13.

[0028] In actual manufacturing, the elastic washer 10 includes a metal washer 102, and the metal washer 102 is covered with a rubber washer 101.

[0029] The sealing ring 9 includes a metal retainer 92, and a rubber ring 91 is wrapped around the outside of the metal retainer 92.

[0030] The use of the elastic washer 10 absorbs external impact forces on the suspension bearing, converting large vibrations into smaller ones and improving the service life of the suspension bearing. Furthermore, the metal washer 102 increases the strength of the elastic washer 10, making it less prone to deformation and damage. Even further, the metal cage 92 increases the strength of the sealing ring 9, making it less prone to deformation and improving sealing performance.
