Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a bushing inner tube that is easy to maintain. Background Technology

[0002] In automotive parts, the inner tube of the bushing (usually referring to the tubular component installed inside the bushing) has different functions depending on the vehicle model and installation location. However, in general, its core function is to ensure the normal operation of the vehicle's related systems by optimizing mechanical connections, reducing friction, and improving component stability. The inner tube of the bushing, together with the outer rubber layer (or metal shell) of the bushing, forms a rigid support frame, restricting the movement of the component in unexpected directions.

[0003] To limit the relative movement between the inner and outer tubes, existing bushing inner tubes typically have hard impact blocks on the outer wall of the inner tube, with a layer of soft rubber impact block vulcanized in the middle of the hard impact blocks to provide cushioning. However, with long-term use, the soft impact blocks will wear down. In addition, since the hard impact blocks, soft impact blocks and the inner tube of the bushing are integrated into one design, the entire inner tube of the bushing must be replaced when replacement is needed, which increases maintenance costs. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a bushing inner tube that is easy to maintain and reduces maintenance costs, in order to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bushing inner tube that is easy to maintain, comprising a bushing inner tube body, wherein a through hole is provided in the middle of the bushing inner tube body, characterized in that: a first limiting member is provided on the outer wall of the bushing inner tube body, and a second limiting member is provided on the outer wall of the bushing inner tube body below the first limiting member, and an installation groove is provided between the first limiting member and the second limiting member, wherein a wear-resistant part is detachably provided in the installation groove.

[0006] The above technical solution utilizes a mounting groove and a detachable wear-resistant component, allowing the wear-resistant component to be individually removed from the inner tube of the bushing for replacement after wear occurs during long-term use, eliminating the need to replace the entire inner tube and reducing maintenance costs. Furthermore, the first and second limiting components are preferably made of metal, while the wear-resistant component is made of rubber. This allows the wear-resistant component to compress and absorb energy during relative movement between the inner and outer tubes, reducing impact and preventing relative movement. When the wear-resistant component wears to a certain extent, the first and second limiting components can forcibly limit its movement.

[0007] A further feature of this invention is that the wear-resistant component includes a first wear-resistant fan ring and a second wear-resistant fan ring, which are connected by a detachable connection structure, and a through hole is formed between the first wear-resistant fan ring and the second wear-resistant fan ring to connect with the mounting groove.

[0008] The above technical solution involves dividing the wear-resistant part into a first wear-resistant fan ring and a second wear-resistant fan ring, and making both detachable, which facilitates the installation of the wear-resistant part into the mounting slot by the operator.

[0009] A further feature of this invention is that the first wear-resistant fan ring has plug-in blocks at both ends of its opening, and the second wear-resistant fan ring has plug-in holes at both ends of its opening for installing the plug-in blocks.

[0010] The above technical solution involves first installing the second wear-resistant fan ring into the mounting groove, then aligning the plug on the first wear-resistant fan ring with the plug hole on the second wear-resistant fan ring, and finally installing it into the mounting groove to complete the installation between the first and second wear-resistant fan rings.

[0011] A further feature of this invention is that positioning grooves are provided on the outer walls of the first wear-resistant fan ring and the second wear-resistant fan ring.

[0012] The above technical solution is adopted: by setting the positioning groove, and at the same time, the positioning block that matches the positioning groove is provided in the corresponding outer tube, which can play a positioning role and facilitate the positioning by the staff before assembly.

[0013] A further feature of this invention is that a sealing groove is provided at both ends of the outer wall of the inner tube of the bushing, and a sealing ring is embedded in the sealing groove.

[0014] The above technical solution is adopted: by setting a sealing ring together with a sealing groove, when the inner tube of the bushing is installed into the outer tube, the outer side of the sealing ring abuts against the inner wall of the outer tube, thereby improving the sealing performance between the inner and outer tubes.

[0015] A further feature of this invention is that the inner tube of the bushing has connecting parts at both ends, and the upper surface of the connecting parts has several anti-slip protrusions.

[0016] The above technical solution is adopted: by setting anti-slip ridges, when connected with other components, the anti-slip ridges can play an anti-slip role.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0023] like Figure 1-4 The illustrated bushing inner tube for easy maintenance includes a bushing inner tube body 1, with a through hole 11 penetrating through the middle of the bushing inner tube body 1. A first limiting member 12 is protruding on the outer wall of the bushing inner tube body 1, and a second limiting member 13 is protruding on the outer wall of the bushing inner tube body 1 below the first limiting member 12. An installation groove 14 is provided between the first limiting member 12 and the second limiting member 13, and a wear-resistant part 2 is detachably provided in the installation groove 14.

[0024] like Figure 2-4 The wear-resistant component 2 shown includes a first wear-resistant fan ring 21 and a second wear-resistant fan ring 22. The first wear-resistant fan ring 21 and the second wear-resistant fan ring 22 are connected by a detachable connection structure, and a through hole 23 connected to the mounting groove 14 is formed between the first wear-resistant fan ring 21 and the second wear-resistant fan ring 22.

[0025] like Figure 2-3 The first wear-resistant fan ring 21 shown has plug-in blocks 212 at both ends of its opening, and the second wear-resistant fan ring 22 has plug-in holes 221 for installing the plug-in blocks 212 at both ends of its opening. Positioning grooves 24 are provided on the outer walls of the first wear-resistant fan ring 21 and the second wear-resistant fan ring 22.

[0026] like Figure 1-3 The outer wall of the bushing inner tube shown is provided with sealing grooves 15 at both ends, and sealing rings 151 are embedded in the sealing grooves 15; the bushing inner tube is provided with connecting parts 16 at both ends, and several anti-slip protrusions 161 are provided on the upper surface of the connecting parts 16.

[0027] In use, the detachable mounting groove 14 and wear-resistant part 2 allow the wear-resistant part 2 to be easily removed from the inner tube of the bushing for replacement after wear occurs due to long-term use, eliminating the need to replace the entire inner tube and reducing maintenance costs. Furthermore, the first limiting member 12 and the second limiting member 13 are preferably made of metal, while the wear-resistant part 2 is made of rubber. This ensures that when the inner and outer tubes move relative to each other, the wear-resistant part 2 first compresses and absorbs energy, reducing impact and preventing relative movement between the inner and outer tubes. When the wear-resistant part 2 wears to a certain extent, the first limiting part 12 and the second limiting part 13 can be forcibly limited. At the same time, the wear-resistant part 2 includes a first wear-resistant fan ring 21 and a second wear-resistant fan ring 22. During the installation process, the second wear-resistant fan ring 22 is first installed into the mounting groove 14, and then the plug block 212 on the first wear-resistant fan ring 21 is aligned with the plug hole 221 on the second wear-resistant fan ring 22 and installed into the mounting groove 14 to complete the installation between the first wear-resistant fan ring 21 and the second wear-resistant fan ring 22.
