Description

Technical Field

[0001] This utility model relates to the field of automotive bushing technology, specifically to an adjustable hydraulic bushing. Background Technology

[0002] Hydraulic bushings are important components used in hydraulic systems, typically to support and protect piston rods or plungers. As people's living standards improve, they are paying more and more attention to the comfort of vehicles during driving, and the requirements for vehicle NVH (noise, vibration, and harshness) performance are getting higher and higher. Many mid-to-high-end vehicles connect the front lower control arm and subframe through hydraulic bushings. Hydraulic bushings can effectively absorb vibrations from the roadside under low-frequency, large-amplitude conditions.

[0003] In the prior art, during long-term use, the seals of hydraulic bushings may wear or age, leading to hydraulic oil leakage, which affects the performance and safety of the system. In addition, hydraulic systems are sensitive to temperature changes. Excessively high or low temperatures may affect the viscosity of hydraulic oil, thereby affecting the working performance of hydraulic bushings. Regular inspection and maintenance are required, especially the replacement of seals and hydraulic oil, which increases maintenance costs and workload.

[0004] To address this, an adjustable hydraulic bushing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable hydraulic bushing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable hydraulic bushing, including a skeleton, a through hole at the center of the skeleton, an outer tube fixedly connected to the bottom of the skeleton, an inner tube fixedly connected to the center of the inner wall of the outer tube, a first buffer plate threadedly connected to one side of the outer wall of the outer tube, a second buffer plate threadedly connected to the other side of the outer wall of the outer tube, a snap-fit ​​part rotatably connected to the middle of both front ends of the second buffer plate, and a mating block fixedly connected to the middle of both front ends of the first buffer plate.

[0007] Preferably, the fastening part and the mating block are connected by a snap-fit.

[0008] Preferably, rubber protrusions are fixedly connected to the outer walls of both the first and second buffer plates.

[0009] Preferably, the second buffer plate has U-shaped notches on both the upper and lower sides of its outer wall, and the U-shaped notches are staggered.

[0010] Preferably, the first buffer plate and the second buffer plate have connection ports on their upper and lower front ends.

[0011] Preferably, the inner wall of the outer tube has a flow channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting a detachable and installable buffer layer structure on the outer wall of the outer tube, the buffer layer can effectively absorb and reduce external impacts and vibrations, protect the outer tube and its internal components, and extend the service life of the equipment. The detachable design makes the installation and replacement of the buffer layer more convenient, reducing maintenance time and costs. According to different working environments and needs, the material and thickness of the buffer layer can be flexibly adjusted or replaced to adapt to different application scenarios. The buffer layer can effectively reduce noise caused by vibration and impact, provide additional protection, prevent the outer tube from being directly hit by external objects, and reduce the risk of damage.

[0014] 2. The buffer layer effectively absorbs and mitigates external impacts and vibrations, protecting the bushing and its internal components, extending the service life of the equipment. The detachable design makes the installation and replacement of the buffer layer more convenient. The buffer layer provides additional protection, preventing the bushing from being directly impacted by external objects and reducing the risk of damage. By reducing impacts and vibrations, the buffer layer can reduce the risk of equipment failure, thereby improving the overall system safety, reducing wear and impacts, and helping to extend the service life of the bushing and its related components, reducing the frequency of replacement.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 2 An embodiment of this utility model is provided: an adjustable hydraulic bushing, including a skeleton 1, a through hole 2 at the center of the skeleton 1, an outer tube 3 fixedly connected to the bottom of the skeleton 1, an inner tube 4 fixedly connected to the center of the inner wall of the outer tube 3, a first buffer plate 5 threadedly connected to one side of the outer wall of the outer tube 3, a second buffer plate 6 threadedly connected to the other side of the outer wall of the outer tube 3, a fastening part 7 rotatably connected to the middle of both sides of the front end of the second buffer plate 6, and a mating block 8 fixedly connected to the middle of both sides of the front end of the first buffer plate 5.

[0023] Wherein: the diameter of the through hole 2 corresponds to that of the inner tube 4;

[0024] Better yet: The first buffer plate 5 and the second buffer plate 6, which are rotatably connected, are fitted through the outer wall of the outer tube 3, and the two fastening parts 7 on both sides are respectively fastened to the outer wall of the mating block 8, so that the first buffer plate 5 and the second buffer plate 6 can form a whole and rotate to a suitable position through the threaded groove on the outer wall of the outer tube 3.

[0025] The fastening part 7 is connected to the mating block 8 by a snap fastening. Rubber protrusions 9 are fixedly connected to the outer walls of the first buffer plate 5 and the second buffer plate 6. U-shaped notches 10 are opened on the upper and lower sides of the outer wall of the second buffer plate 6. The two U-shaped notches 10 are staggered. The upper and lower front ends of the first buffer plate 5 and the second buffer plate 6 are opened with connecting ports 11. The inner wall of the outer tube 3 is opened with a flow channel 12.

[0026] Among them: the rubber protrusion 9 is set as a semi-cylindrical shape, and the flow channel 12 is set as a spiral groove shape;

[0027] Even better: the semi-circular rubber protrusion 9 can effectively absorb and reduce external impact and vibration, protecting the bushing and its internal components; the U-shaped notch 10 makes it easier to connect the first buffer plate 5 and the second buffer plate 6; and the flow channel 12 allows the antifreeze to flow and distribute evenly in the inner wall of the outer tube 3 and the inner tube 4.

[0028] The working principle of the above implementation is as follows:

[0029] The operation steps are as follows:

[0030] The first buffer plate 5 and the second buffer plate 6, which are rotatably connected, are fitted through the outer wall of the outer tube 3, and the two fastening parts 7 on both sides are respectively fastened to the outer wall of the mating block 8, so that the first buffer plate 5 and the second buffer plate 6 can form a whole and rotate to the appropriate position through the threaded groove on the outer wall of the outer tube 3. The semi-circular rubber protrusion 9 can effectively absorb and reduce external impact and vibration, and protect the bushing and its internal components. The U-shaped notch 10 makes it more convenient to connect the first buffer plate 5 and the second buffer plate 6. The flow channel 12 allows the antifreeze to flow and distribute evenly in the inner wall of the outer tube 3 and the inner tube 4.

[0031] A detachable buffer layer structure is installed on the outer wall of the outer tube 3. The buffer layer can effectively absorb and mitigate external impacts and vibrations, protect the outer tube 3 and its internal components, and extend the service life of the equipment. The detachable design makes the installation and replacement of the buffer layer more convenient, reducing maintenance time and costs. The material and thickness of the buffer layer can be flexibly adjusted or replaced according to different working environments and needs to adapt to different application scenarios. The buffer layer can effectively reduce noise caused by vibration and impact, provide additional protection, prevent the outer tube 3 from being directly impacted by external objects, and reduce the risk of damage. By reducing impact and vibration, the buffer layer can reduce the risk of equipment failure, thereby improving the safety of the overall system, reducing wear and impact, and helping to extend the service life of the bushing and its related components, reducing the replacement frequency.
