Description

Technical Field

[0001] This utility model belongs to the field of automotive bushing technology, and in particular relates to a drum-shaped shock absorber bushing for automobiles. Background Technology

[0002] Currently, shock absorber bushings are commonly used in automotive suspension systems to connect the chassis to control arms or other vibration-sensitive components, serving to absorb shocks, reduce vibrations, and suppress noise. Among them, drum-shaped bushings are widely used due to their multi-directional flexibility and excellent shock absorption performance.

[0003] In the installation of existing drum-shaped shock absorber bushings, bolts are typically used to fix the bushing to the vehicle body structure or suspension mechanism. This often requires the use of external tools to tighten the bolts and nuts. However, in confined spaces or under chassis conditions, this tightening connection method has low assembly efficiency, is cumbersome, and is prone to thread damage or improper assembly during disassembly and assembly, affecting the overall connection strength and bushing performance. In addition, in some detachable structures, although quick clamping or limiting structures are used, there are still problems such as inaccurate positioning, unstable clamping, and insufficient assembly spring force, which can lead to unreliable bolt positioning or the risk of loosening.

[0004] Based on this, this utility model designs a vehicle shock absorber drum-shaped bushing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the installation of existing drum-shaped shock absorber bushings, bolts are usually required to fix the bushing to the vehicle body structure or suspension mechanism. For this purpose, external tools are often needed to tighten the bolts and nuts. However, in limited space or chassis conditions, this tightening connection method has low assembly efficiency, is cumbersome to operate, and is prone to thread damage or improper assembly during disassembly and assembly. Therefore, a drum-shaped shock absorber bushing for vehicles is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vehicle shock absorber drum bushing includes a housing, an inner bushing, an elastomer, a connecting shell, half nuts, a bolt, a slide, a telescopic rod, a return spring, a pull plate, and an anti-slip pad. The elastomer is disposed on the outer side of the inner bushing. The connecting shell is symmetrically fixedly connected to both sides of the elastomer. Two half nuts are provided inside the connecting shell, and the two half nuts are jointly engaged with the same bolt.

[0008] As a further description of the above technical solution:

[0009] The connecting shell has a sliding groove, and one of the two half nuts can be slidably connected in the sliding groove.

[0010] As a further description of the above technical solution:

[0011] A telescopic rod is fixedly connected to one side of the half nut in the groove, and the other end of the telescopic rod is fixedly connected to the groove.

[0012] As a further description of the above technical solution:

[0013] A return spring is fitted on the outer side of the telescopic rod. One end of the return spring is fixedly connected to one of the half bolts, and the other end of the return spring is fixedly connected to the slide groove.

[0014] As a further description of the above technical solution:

[0015] The upper part of the connecting shell is provided with a long groove, and the pull plate is slidably connected in the long groove.

[0016] As a further description of the above technical solution:

[0017] The pull plate is fixedly connected to the telescopic rod and can be used to drive the movement of the half nut in the slide groove.

[0018] As a further description of the above technical solution:

[0019] An anti-slip pad is fixedly connected to the outer side of the upper end of the pull plate.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, during use, the anti-slip pad is manually pulled, causing the pull plate to slide along the long groove above the connecting shell. This drives the telescopic rod fixedly connected to it to move synchronously, causing the half-nut in the groove to move outward, creating sufficient installation space. At this time, the operator can insert the bolt between the two half-nuts. When the bolt is fully inserted into the shell, the anti-slip pad is released, and the return spring immediately applies a return force to the telescopic rod, causing the half-nut in the groove to automatically reset and engage with the other half-nut. This completes the rapid limiting and stable fixing of the bolt. This device can complete the assembly and fixing of the bolt without the need for any rotating tools. It has the advantages of simple operation steps, short assembly time, and automated structural reset. At the same time, due to the use of groove guidance and spring reset, it can ensure rapid locking action, accurate reset, and reliable positioning, thereby effectively improving the safety stability and service life of the bushing under high vibration and high load conditions.

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4 ,

[0030] This utility model provides a technical solution: a vehicle shock absorber drum bushing, including an outer shell 1, an inner bushing 2, an elastic body 3, a connecting shell 4, half nuts 5, bolts 6, a sliding groove 7, a telescopic rod 8, a return spring 9, a pull plate 10, and an anti-slip pad 11. The elastic body 3 is wrapped around the outer side of the inner bushing 2. The connecting shell 4 is symmetrically fixedly connected to both sides of the elastic body 3. Two half nuts 5 are provided inside the connecting shell 4, and the two half nuts 5 are locked together on the same bolt 6.

[0031] Specifically, such as Figure 2-3As shown, a sliding groove 7 is provided inside the connecting shell 4. One of the two half nuts 5 can be slidably connected in the sliding groove 7. A telescopic rod 8 is fixedly connected to one side of the half nut 5 in the sliding groove 7, and the other end of the telescopic rod 8 is fixedly connected in the sliding groove 7. One end of the telescopic rod 8 is fixed in the sliding groove 7, and the other end is connected to the half nut 5. It can reciprocate within the movement path defined by the sliding groove 7, thereby realizing effective control of the movement direction and amplitude of the half nut 5. This cooperation ensures that the half nut 5 does not deviate from the trajectory when sliding, and improves the stability and guiding accuracy of the structure operation.

[0032] A return spring 9 is sleeved on the outside of the telescopic rod 8. The return spring 9 is sleeved on the telescopic rod 8. When the pull plate 10 drives the telescopic rod 8 to extend, the spring is compressed and stores energy. After the pull plate 10 is released, it can quickly release the elastic force to push the telescopic rod 8 to reset, thereby driving the half nut 5 to move in the turning direction to achieve automatic locking. This mechanism eliminates the manual reset process and improves the operation efficiency and the automatic reset capability of the structure.

[0033] One end of the return spring 9 is fixedly connected to one of the half bolts 6, and the other end of the return spring 9 is fixedly connected to the slide groove 7. A long groove is provided above the connecting shell 4, and the pull plate 10 is slidably connected in the long groove. The pull plate 10 is fixedly connected to the telescopic rod 8 and can be used to drive the half nut 5 in the slide groove 7 to move. An anti-slip pad 11 is fixedly connected to the outer side of the upper end of the pull plate 10. The anti-slip pad 11 is fixed to the outer side of the pull plate 10 and provides an effective anti-slip contact surface during operation. Even in oily or wet environments, it can ensure that the operator can apply force stably and without slipping. This combination improves the accuracy and safety of the user's control of the pull plate 10.

[0034] Working principle and usage: During use, the anti-slip pad 11 is manually pulled, causing the pull plate 10 to slide along the long groove above the connecting shell 4. This drives the telescopic rod 8, which is fixedly connected to it, to move synchronously. This causes the half nut 5 in the slide groove 7 to move outward, creating sufficient installation space. At this time, the operator can insert the bolt 6 between the two half nuts 5. After the bolt 6 is fully inserted into the shell 1, the anti-slip pad 11 is released. The return spring 9 immediately applies a return force to the telescopic rod 8, causing the half nut 5 in the slide groove 7 to automatically reset and engage with the other half nut 5. This completes the rapid limiting and stable fixing of the bolt 6. This device can complete the assembly and fixing of the bolt 6 without the need for any rotating tools. It has the advantages of simple operation steps, short assembly time, and automated structural reset. At the same time, due to the use of the slide groove 7 guide and spring reset, it can ensure rapid locking action, accurate reset, and reliable positioning, thereby effectively improving the safety stability and service life of the bushing under high vibration and high load conditions.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
