[0002] In the existing technology, different driving environments of vehicles require stabilizer bar bushings to adapt to different working conditions. In order to adapt to harsh working conditions, stabilizer bar bushings are equipped with dust covers to achieve dust and water protection for the bushing structure. However, after adding dust covers, the structure of stabilizer bar bushings becomes more complex and the manufacturing cost is higher. Utility Model Content

[0003] In view of this, the present application provides a stabilizer bar bushing in which the dust cover is directly connected to the bushing structure, eliminating the need for a separate mounting base, reducing the assembly process of the dust cover, and lowering the manufacturing cost of the stabilizer bar bushing.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

The bushing structure is sleeved on the outside of the stabilizer bar, and both ends of the bushing structure in the axial direction have protrusions. There are two dust covers, which are respectively provided on both sides of the bushing structure in the axial direction. One end of the dust cover in the axial direction is connected to the protrusion, and the end of the dust cover away from the bushing structure is connected to the outer peripheral wall of the stabilizer bar.

[0006] The stabilizer bar bushing provided in this embodiment can fix the position of the stabilizer bar, ensuring that the stabilizer bar can correctly perform its function of connecting the left and right suspensions and resisting roll. The dust cover can prevent foreign objects and dust from entering the bushing structure, preventing damage to the bushing structure and avoiding failure, thus increasing the adaptability of the stabilizer bar bushing to harsh operating conditions. At the same time, the dust cover is directly connected to the bushing structure, eliminating the need for a separate mounting base, reducing the assembly process of the dust cover, and lowering the manufacturing cost of the stabilizer bar bushing.

[0007] In one possible implementation of this application, the protrusion is spaced apart from both the inner and outer peripheral walls of the bushing structure. The outer peripheral wall of the protrusion is provided with a limiting groove, which is formed in an annular shape. One end of the dust cover in the axial direction has an annular protrusion that mates with the limiting groove. The end of the dust cover away from the bushing structure is connected to the outer peripheral wall of the stabilizer rod.

[0011] In one possible implementation of this application, a lubricating layer is provided between the sleeve and the bushing body.

[0012] In one possible implementation of this application, a first protrusion is provided at one end of the sleeve in the axial direction, the first protrusion extends outward along the radial direction of the sleeve, and a second protrusion is provided at the end of the first protrusion away from the sleeve, the second protrusion being sleeved outside the limiting ring.

[0013] In one possible implementation of this application, the bushing body includes: a first bushing; a second bushing, wherein the first bushing and the second bushing are joined together in a ring shape and sleeved on the outside of the sleeve.

[0014] In one possible implementation of this application, the stabilizer bar bushing further includes a bracket, which is sleeved outside the bushing structure.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0032] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0033] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0034] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0035] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0036] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0037] This application provides a vehicle. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Vehicles are generally equipped with stabilizer bars, which are important components of the vehicle's suspension system. By increasing the stiffness of the suspension system against body roll, they significantly reduce body roll during cornering, thereby improving vehicle handling stability, cornering performance, and tire contact patch.

[0038] Based on this, refer to Figures 1-8 This application provides a stabilizer bar bushing 100, including a bushing structure 10 and a dust cover 20.

[0039] To better illustrate the stabilizer bar bushing 100 provided in this application embodiment, the bushing structure 10 is sleeved on the outside of the stabilizer bar 200. During vehicle operation, the stabilizer bar 200 may come into rigid contact and rub against the metal mounting points of the vehicle body or subframe, generating significant vibration, impact, and harsh metallic friction noise (squeaking sound), which is directly transmitted into the passenger compartment, severely affecting ride comfort and NVH (Noise, Vibration, Harshness) performance. The bushing structure 10 can absorb and isolate the vibration and noise generated by the movement of the stabilizer bar 200 between the stabilizer bar 200 and the metal mounting points of the vehicle body or subframe, preventing vibration and noise from being transmitted to the vehicle body, thereby increasing user comfort and the vehicle's NVH performance.

[0040] Meanwhile, the bushing structure 10 can fix the position of the stabilizer bar 200, ensuring that the stabilizer bar 200 can properly perform its function of connecting the left and right suspensions and resisting body roll.

[0041] The axial direction of bushing structure 10 (e.g.) Figure 1 Both ends of the first direction shown are provided with protrusions 221. There are two dust covers 20, which are respectively provided on both sides of the bushing structure 10 in the axial direction. The axial direction of the dust cover 20 (as shown) Figure 1 One end of the dust cover 20 (shown in the first direction) is connected to the protrusion 221, and the end of the dust cover 20 away from the bushing structure 10 is connected to the outer peripheral wall of the stabilizer bar 200. The dust cover 20 can prevent foreign objects, dust and the like from entering the bushing structure 10, prevent foreign objects, dust and the like from damaging the bushing structure 10, prevent the bushing structure 10 from failing, and increase the adaptability of the stabilizer bar bushing 100 to harsh working conditions.

[0042] Meanwhile, the dust cover 20 is directly connected to the bushing structure 10, eliminating the need for a separate mounting base, which reduces the assembly process of the dust cover 20 and lowers the manufacturing cost of the stabilizer bar bushing 100.

[0043] According to the stabilizer bar bushing 100 of this application embodiment, the bushing structure 10 can fix the position of the stabilizer bar 200, ensuring that the stabilizer bar 200 can correctly perform its function of connecting the left and right suspensions and resisting roll. The dust cover 20 can prevent foreign objects, dust, etc. from entering the bushing structure 10, preventing foreign objects, dust, etc. from damaging the bushing structure 10 and causing the bushing structure 10 to fail, thus increasing the adaptability of the stabilizer bar bushing 100 to harsh working conditions. At the same time, the dust cover 20 is directly connected to the bushing structure 10, eliminating the need for a separate mounting base, reducing the assembly process of the dust cover 20, and lowering the manufacturing cost of the stabilizer bar bushing 100.

[0044] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The protrusion 221 is spaced apart from both the inner and outer peripheral walls of the bushing structure 10. The outer peripheral wall of the protrusion 221 is provided with a limiting groove 222, which is formed in an annular shape. One end of the dust cover 20 in the axial direction has an annular protrusion 202 that cooperates with the limiting groove 222. The end of the dust cover 20 away from the bushing structure 10 is connected to the outer peripheral wall of the stabilizer 200.

[0045] It is understandable that the dust cover 20 is an elastic component. During the assembly of the dust cover 20, the part of the dust cover 20 near the bushing structure 10 can be appropriately extended, thereby increasing the inner diameter of the part of the dust cover 20 near the bushing structure 10. Then, the annular protrusion 202 is locked in the limiting groove 222 to limit the dust cover 20. The assembly process of the dust cover 20 is relatively simple.

[0046] In this application, the dust cover 20 is a rubber part with good elasticity and a large deformation.

[0047] In this application, the end of the dust cover 20 furthest from the bushing structure 10 is connected to the outer peripheral wall of the stabilizer bar 200 via a clamp 40. This connection allows for quick installation and provides a good seal, making it waterproof and dustproof. Furthermore, the clamp 40 can be removed to disengage the dust cover 20 from the bushing structure 10 and the stabilizer bar 200, facilitating maintenance or replacement of the bushing structure 10.

[0048] Meanwhile, the cooperation of the annular limiting groove 222 and the annular protrusion 202 allows the dust cover 20 and the bushing structure 10 to rotate relative to each other about the axis of the stabilizer bar 200. When the stabilizer bar 200 and the stabilizer bar bushing 100 twist slightly, the stabilizer bar bushing 100 can rotate relative to the dust cover 20, avoiding the dust cover 20 from twisting and being damaged when the stabilizer bar bushing 100 twists, thus increasing the reliability of the dust cover 20.

[0049] In some embodiments of this application, reference is made to Figure 1 At any cross section passing through the axis of stabilizer bar 200, the cross section of dust cover 20 located on one side of the axis of stabilizer bar 200 includes multiple sections along the axial direction of stabilizer bar 200 (e.g., Figure 1 The steps 201 arranged in the first direction (as shown) decrease in outer diameter sequentially along the direction away from the bushing structure 10. When the dust cover 20 is subjected to axial tension, its axial length is the sum of the axial lengths of the multiple steps 201. When the dust cover 20 is subjected to radial tension, its radial length is the sum of the radial lengths of the multiple steps 201. This can increase the axial and radial lengths of the dust cover 20 under extreme conditions, increase the amount of deformation of the dust cover 20, and increase the ability of the dust cover 20 to cope with the relative movement of the stabilizer bar 200 and the bushing structure 10.

[0050] In some embodiments of this application, reference is made to Figure 1 , Figure 5 and Figure 8 The bushing structure 10 includes a limiting ring 1 and a bushing assembly 2. The limiting ring 1 is sleeved on and fixedly connected to the stabilizer bar 200. The bushing assembly 2 is sleeved outside the stabilizer bar 200. At least one side of the bushing assembly 2 in the axial direction is provided with the limiting ring 1, which abuts against one end of the bushing assembly 2 in the axial direction. Protrusions 221 are provided at both ends of the bushing assembly 2 in the axial direction. The limiting ring 1, which is fixedly connected to the fixed bar, can limit the bushing assembly 2, reduce the displacement of the bushing assembly 2 in the axial direction of the stabilizer bar 200, and increase the reliability of the position of the stabilizer bar bushing 100 in the axial direction of the stabilizer bar 200.

[0051] In some embodiments of this application, reference is made to Figure 1 and Figure 2The bushing assembly 2 includes a sleeve 21 and a bushing body 22. The sleeve 21 is fitted over the stabilizer bar 200, and the limiting ring 1 abuts against one end of the sleeve 21 in the axial direction. The bushing body 22 is fitted over the sleeve 21, and protrusions 221 are located at both ends of the bushing body 22 in the axial direction. In this embodiment, both the sleeve 21 and the bushing body 22 are plastic parts, which can increase the radial stiffness of the bushing assembly 2 and resist the deformation of the stabilizer bar 200 in the radial direction. The bushing body 22 can be made of plastic materials such as PA (Polyamide), POM (Polyformaldehyde), PBT (Polybutylene terephthalate), PTFE (Polytetrafluoroethylene), and PEEK (Polyetheretherketone), and the material of the bushing body 22 can be selected according to requirements.

[0052] In some embodiments of this application, reference is made to Figure 1 and Figure 2 A lubrication layer 23 is provided between the sleeve 21 and the bushing body 22, which can reduce the torsional stiffness between the sleeve 21 and the bushing body 22. When the stabilizer bar 200 drives the stabilizer bar bushing 100 to rotate, the sleeve 21 and the bushing body 22 can rotate relative to each other, avoiding problems such as breakage when the stabilizer bar bushing 100 rotates.

[0053] In some embodiments of this application, reference is made to Figure 1 and Figure 2 One end of the sleeve 21 in the axial direction is provided with a first protrusion 211, which extends outward along the radial direction of the sleeve 21. The end of the first protrusion 211 away from the sleeve 21 is provided with a second protrusion 212, which is sleeved on the outside of the limiting ring 1. This can increase the limiting effect of the limiting ring 1 on the sleeve 21, while preventing the bushing body 22 from displacing in the direction closer to the limiting ring 1, and preventing the bushing body 22 from disengaging from the sleeve 21.

[0054] In this embodiment, the limiting ring 1 is riveted to the stabilizing rod 200, and the sleeve 21 and the first protrusion 211 and the second protrusion 212 on the sleeve 21 are integrally injection molded, so that the relative position between the sleeve 21 and the limiting ring 1 and the stabilizing rod 200 is relatively stable.

[0055] In some embodiments of this application, reference is made to Figure 1 , Figures 4-7 The bushing body 22 includes a first bushing 223 and a second bushing 224. The first bushing 223 and the second bushing 224 are spliced ​​into a ring and sleeved outside the sleeve 21 to facilitate the assembly of the bushing body 22 and the sleeve 21.

[0056] The first bushing 223 and the second bushing 224 are glued together, and the connection method is relatively simple.

[0057] In some embodiments of this application, reference is made to Figures 1-3 The stabilizer bar bushing 100 also includes a bracket 30, which is sleeved outside the bushing structure 10. The bracket 30 can limit the bushing structure 10 in the radial direction, and the bracket 30 can be provided with mounting holes 301 for connecting with the vehicle's subframe assembly and other parts.

[0058] The vehicle according to the embodiments of this application, referring to Figure 2 and Figure 3 The system includes a stabilizer bar 200 and stabilizer bar bushings 100. Two stabilizer bar bushings 100 are provided at opposite ends of the stabilizer bar 200 along its length. A bushing structure 10 is fitted over the outside of the stabilizer bar 200. A limiting ring 1 within each stabilizer bar bushing 100 is located on the side of the bushing structure 10 closest to the other stabilizer bar bushing 100, preventing the two stabilizer bar bushings 100 from moving closer to each other.

[0059] According to the vehicle embodiment of this application, the bushing structure 10 can fix the position of the stabilizer bar 200, ensuring that the stabilizer bar 200 can correctly perform its function of connecting the left and right suspensions and resisting body roll. The dust cover 20 can prevent foreign objects, dust, etc. from entering the interior of the bushing structure 10, preventing foreign objects, dust, etc. from damaging the bushing structure 10 and causing the bushing structure 10 to fail, thus increasing the adaptability of the stabilizer bar bushing 100 to harsh working conditions. At the same time, the dust cover 20 is directly connected to the bushing structure 10, eliminating the need for a separate mounting bracket, reducing the assembly process of the dust cover 20, and lowering the manufacturing cost of the stabilizer bar bushing 100.

The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
