Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and more specifically to an easily adjustable bushing structure for automobiles. Background Technology

[0002] Currently, an automotive bushing disclosed in CN116066514A includes a multi-layered stacked bushing with an interference fit between each layer. Each layer has a different stiffness value. During the interference fit, the stiffness values ​​of the multiple layers are connected in series. When the vibration load is small and the frequency is high, the bushing with the smaller stiffness value plays a dominant role, while the bushing with the larger stiffness value does not vibrate due to the load, thus providing good vibration isolation. As the load gradually increases, the bushing with the smaller stiffness value is gradually crushed, and the bushing with the larger stiffness value participates in bearing the load. This gradually increases the load-bearing capacity of the automotive bushing, while the bushing with the larger stiffness value retains its elasticity until its load-bearing limit is reached. When the bushing with the larger stiffness value is crushed, it limits excessive displacement of the power system and protects other components from damage.

[0003] However, in the process of automobile development, as the performance requirements of automobiles become higher and higher, the performance requirements for different road conditions are also constantly being improved. Consequently, the structural requirements for bushings are becoming more and more stringent. The current bushing structure is an integral structure. During use, the bushing is generally subjected to forces in four directions, and the forces in the four directions are different. Therefore, how to meet the customer's vehicle installation and performance requirements according to different usage conditions is an urgent problem to be solved for bushings.

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Therefore, the following detailed description of embodiments of the invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] The adjustable bushing structure in this embodiment requires a bushing that can be freely replaced, adjusted, and optimized in four directions to meet customer requirements for vehicle installation and performance. This allows for meeting different road test performance requirements, and existing processes and frame structures can meet manufacturing needs. To satisfy these requirements, this invention proposes a novel bushing structure that facilitates performance adjustment.

[0034] like Figure 1 As shown, the bushing structure in this embodiment is mainly composed of an outer tube 10, an inner tube 20, and a performance slider 30.

[0035] like Figures 1-6 As shown, the outer tube 10 has a cylindrical structure with an outer side 101 and an inner side 102 arranged opposite to each other. Four first slots 11 are provided on the inner side 102 of the outer tube 10, extending through its height direction. The four first slots 11 are distributed at 90° intervals.

[0036] The inner tube 20 is correspondingly disposed inside the outer tube 10, generally located at the center. The inner tube 20 includes a tube portion 21 and a support portion 22. The support portion 22 is disposed around the tube portion 21. Both ends of the tube portion 21 extend to the outside of the support portion 22 and form locking ends 211. The support portion 22 is provided with a plurality of second slots 221 extending through its height direction. The support portion 22 has four straight side end faces 222 connected in sequence. The second slots 221 are disposed on the side end faces 222. The surface where the rubber part 33 connects to the connecting part 32 is a straight end face. The position of the second slot 221 corresponds to the position of the first slot 11.

[0037] And four detachable performance sliders 30 are disposed between the outer tube 10 and the inner tube 20. The performance sliders 30 include rubber parts 33 and connecting parts 31 and 32 fixedly disposed at opposite ends of the rubber parts 33. The connecting parts 31 and 32 are respectively inserted and connected to the outer tube 10 and the inner tube 20. Thus, the rubber parts 33 are evenly distributed in the gap between the outer tube 10 and the inner tube 20, and are evenly divided into four directions.

[0038] Meanwhile, a locking ring 40 is fitted on the locking end 211. The end face of the locking ring 40 fits against the end face of the support part 22, and the locking ring 40 covers the corresponding end faces of the second slot 221 and the connecting member 32 located in the second slot 221.

[0039] The surface where the rubber component 33 connects to the second connector 32 is a straight end face, while the surface where the rubber component 33 connects to the first connector 31 is an arc surface. The center of the arc surface coincides with the center of the inner surface 102 of the outer tube 10. Furthermore, the thickness of the rubber component 33 gradually increases from the end closest to the inner tube 20 to the end closest to the outer tube 10.

[0040] Specifically, the second connector 32 includes a second end plate 321 and a second plug plate 322 connected to each other. The second end plate 321 is connected to the flat end face of the rubber part 33, and the second plug plate 322 is used to insert into the second slot 221.

[0041] Additionally, the connector 31 includes a first end plate 311 and a first plug plate 312 connected to each other. The first end plate 311 is connected to the arc surface of the rubber component 33, and the first plug plate 312 is used to insert into the first slot 11.

[0042] Meanwhile, a positioning groove 201 is opened inside the tube section 21 to achieve precise positioning and ensure accurate assembly of the bushing, thereby ensuring performance in the specified direction.

[0043] It should be noted that the performance slider 30 has an interference fit with the outer tube 10 and a clearance fit with the inner tube 20, and the locking end 211 has an interference fit with the locking ring 40. This prevents the performance slider from falling off and separating when subjected to axial force, and also facilitates disassembly and replacement.

[0044] The four performance sliders are four independent bushing structures, which can be adjusted separately as well as the rubber structure, rubber hardness, and formula of the bushings to meet the performance requirements of vehicle installation.

[0045] This invention uses a four-performance slider structure to flexibly adjust the performance of the bushing in four directions. Because the bushing structure is simple and does not involve difficult production processes, traditional vulcanization mold equipment and processes can meet the production requirements. The product structure is simple, and the structure and matching process of the outsourced parts are very common. Therefore, this invention reduces the difficulty of manufacturing process while making it extremely convenient to adjust the performance requirements of the bushing in four directions, which greatly improves the technical level of existing bushing debugging.
