Description

Technical Field

[0001] This utility model relates to the technical field of automotive suspension bushing assembly, specifically to an automotive suspension bushing assembly. Background Technology

[0002] Engine mounts connect the vehicle's powertrain to the chassis, serving to reduce vibration and noise, and limiting the engine's displacement under extreme operating conditions. In recent years, to improve engine efficiency and reduce fuel consumption, engine combustion pressure and excitation have been continuously increasing. Therefore, the requirements for engine mounts have become increasingly stringent. Due to the overall vehicle layout, the six degrees of freedom of the engine mount system are coupled, leading to increased engine amplitude and a wider vibration frequency band. To achieve better vibration isolation, softer mount elements are needed. This results in significant displacement of the engine and its powertrain, making it prone to interference with surrounding components. Therefore, the design of the mounts should consider a limiting mechanism with an ideal curve, which does not affect the vibration isolation of the mount system but effectively limits the displacement of the powertrain. A long service life is also required to support the full weight of the powertrain.

[0003] Current automotive mounting bushing assemblies typically place pure rubber bushings directly into the housing. While ensuring stability, this avoids the low strength issues associated with rubber materials and effectively reduces vibrations during use. However, in actual use, different vehicle specifications have maintenance differences. During the connection between the housing and the vehicle's internal parts, slight differences in distance or position may cause the device to be incompatible, affecting the flexibility of its use. Therefore, we propose an automotive mounting bushing assembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automotive suspension bushing assembly, which solves the problem that in actual use, due to differences in maintenance specifications between different vehicles, slight differences in distance or position during the connection between the outer shell and the vehicle's internal parts may cause the device to be incompatible, affecting the flexibility of the device's use.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An automotive mounting bushing assembly includes a bushing outer tube, a connecting frame fixedly installed on the outer wall of the bushing outer tube, two sliding grooves on both sides of the inner side of the connecting frame, two connecting plates inside the connecting frame, and sliding blocks fixedly installed on both sides of the connecting plates. The connecting plates are engaged inside the connecting frame through the sliding blocks and the sliding grooves.

[0007] Preferably, the top surface of the connecting plate has two first threaded holes, and bolts are threaded into the first threaded holes.

[0008] Preferably, the bushing body is fitted inside the outer tube of the bushing, and a side cover is fixedly installed on one side of the outer tube of the bushing.

[0009] Preferably, the outer tube of the bushing has a first through hole, and the outer tube of the bushing has two limiting holes, which are arc-shaped holes. The inner tube of the bushing is fixedly installed inside the outer tube of the bushing. A pin is fixedly installed on one side of the inner tube of the bushing. The pin extends out of the outer tube of the bushing through the first through hole. Two limiting blocks are fixedly installed on one side of the inner tube of the bushing. The two limiting blocks extend out of the outer tube of the bushing through the two limiting holes.

[0010] Preferably, the outer wall of the bushing outer tube is provided with a connecting block, the connecting block has a Z-shaped structure, the top surface of the connecting block has a second through hole, and the top surface of the connecting block has a second threaded hole.

[0011] Preferably, a connecting rod is fixedly installed on the top surface of the outer tube of the bushing. The connecting rod consists of a cylindrical part and a disc part. The connecting block is engaged with the cylindrical part of the connecting rod through the second through hole.

[0012] In summary, the present invention has the following main advantages:

[0013] 1. By setting a sliding groove, on the one hand, it can form a snap-fit ​​relationship with the sliding blocks on both sides of the connecting plate, which facilitates the disassembly of the connecting plate at any time while ensuring stability. On the other hand, the sliding groove can provide a certain degree of buffer for the connecting plate, so that the device can still adapt to the slight differences in the interior of different cars and make fine adjustments to the connection position, increasing the universality of the device.

[0014] 2. By setting the connecting block, the angle can be rotated at any time, so that the second threaded hole can be aligned with the connecting hole at different angles. This makes it easy for the device to be installed in vehicles even when there are differences in the installation position of the parts inside the vehicle, which further increases the universality of the device. Through the design of the connecting rod, the connecting block can be snapped together with it through the second through hole. While ensuring the stability during installation, it can be disassembled and installed at any time. When the connecting block device is not needed for connection, it can be disassembled at any time to avoid occupying the space inside the vehicle body. Attached Figure Description

[0019] 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.

[0020] refer to Figures 1-3 An automotive suspension bushing assembly includes a bushing outer tube 1. A connecting frame 2 is fixedly installed on the outer wall of the bushing outer tube 1. Two sliding grooves 3 are opened on both sides of the inner side of the connecting frame 2. Two connecting plates 4 are arranged inside the connecting frame 2. Sliding blocks 5 are fixedly installed on both sides of the connecting plates 4. The connecting plates 4 are engaged with the inner side of the connecting frame 2 through the sliding blocks 5 and the sliding grooves 3. Through the design of the sliding grooves 3, on the one hand, they can form a snap-fit ​​relationship with the sliding blocks 5 on both sides of the connecting plates 4, which facilitates the disassembly of the connecting plates 4 at any time while ensuring stability. On the other hand, the sliding grooves 3 can provide a certain degree of buffer for the connecting plates 4. When there are slight differences in the interior of different cars, the device can still be adapted and the connection position can be finely adjusted, increasing the universality of the device.

[0021] The top surface of the connecting plate 4 has two first threaded holes 6. These holes 6 are designed to be threaded together with bolts 7 for installation of the device body and internal vehicle components, ensuring they can perform their functions in a fixed position. Bolts 7 are threaded into the first threaded holes 6. A bushing body 8 is fitted inside the outer bushing tube 1. The bushing body 8, through its easily deformable nature, protects the inner wall of the outer bushing tube 1 and the surface of the connected components, effectively reducing wear during operation and indirectly increasing the service life of the device and internal vehicle components. A side cover 9 is fixedly installed on one side of the outer bushing tube 1. The bushing outer tube 1 has a first through hole 10 inside. The bushing outer tube 1 has two limiting holes 11 inside, each with an arc-shaped structure. A bushing inner tube 12 is fixedly installed inside the bushing outer tube 1. A pin 13 is fixedly installed on one side of the bushing inner tube 12, extending out of the bushing outer tube 1 through the first through hole 10. Two limiting blocks 14 are fixedly installed on one side of the bushing inner tube 12, extending out of the bushing outer tube 1 through the two limiting holes 11. The design of the limiting blocks 14 allows them to extend out of the bushing outer tube 1 through the limiting holes 11, thus limiting the movement of the connecting parts and reducing lateral wobbling after connection with internal automotive components. To address the issue of instability, the limiting hole 11 can also limit the movement of the inner tube 12 of the bushing, effectively preventing vibration of the inner tube 12 inside the outer tube 1 of the bushing and affecting the actual use of the device. The pin 13 serves as the main connecting component, allowing the device to connect normally with internal automotive parts. A connecting block 15 with a Z-shaped structure is provided on the outer wall of the outer tube 1. The top surface of the connecting block 15 has a second through hole 16 and a second threaded hole 17. The design of the connecting block 15 allows for rotation at any time, enabling the second threaded hole 17 to connect with connecting holes at different angles. Alignment is achieved so that even when there are differences in the installation position of parts inside the vehicle, the device can still be adapted to the vehicle for installation, further increasing the universality of the device. A connecting rod 18 is fixedly installed on the top surface of the bushing outer tube 1. The connecting rod 18 consists of a cylindrical part and a disc part. The connecting block 15 is snapped together with the cylindrical part of the connecting rod 18 through the second through hole 16. Through the design of the connecting rod 18, the connecting block 15 can be snapped together with it through the second through hole 16. While ensuring the stability during installation, it can be disassembled and installed at any time. When the connecting block 15 is not needed for connection, it can be disassembled at any time to avoid occupying the space inside the vehicle body.
