Description

Technical Field

[0001] This utility model relates to the field of suspension damping bushing technology, and more specifically, to a high-performance engine suspension damping bushing. Background Technology

[0002] Today, the suspension system refers to a connecting structural system between the vehicle body, frame, and wheels. This system includes components such as shock absorbers, suspension springs, anti-roll bars, suspension subframes, lower control arms, longitudinal bars, steering knuckle arms, rubber bushings, and linkages. When a car is driving on the road, it experiences vibrations and impacts due to changes in the road surface. Some of these impact forces are absorbed by the tires, but the vast majority are absorbed by the suspension system between the tires and the vehicle body. However, most engine mount control arm bushings on the market have drawbacks such as weak shock absorption performance.

[0003] Engine mount swing arm bushings on the market have low assembly precision and weak shock absorption performance, resulting in large vibration amplitude when the engine starts. The bushing is prone to breakage when installed with the housing. The bushing lacks a buffer device, making it easily damaged by impact and inconvenient to replace and repair. These issues result in low safety assurance and high difficulty in replacement and repair. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-performance engine suspension damping bushing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-performance engine suspension damping bushing, including a connecting frame, wherein an engine suspension damping bushing auxiliary device is provided at the front end of the connecting frame, the engine suspension damping bushing auxiliary device including: a positioning component and a damping knob replacement component, and one end of the connecting frame is provided on the outer wall of the side of the positioning component.

[0006] In a preferred embodiment, the positioning assembly includes: an assembly screw, an assembly screw hole group, a positioning frame, a rotating adapter outer shaft, a rotating mounting groove, and an outer bushing. The inner side of the rotating adapter outer shaft is disposed at both ends of the outer bushing, and the rotating mounting groove is formed on the inner side of the rotating adapter outer shaft.

[0007] In a preferred embodiment, the damping knob replacement assembly includes: an inlet / outlet slot, a bushing shaft, an upper transmission pipe, a lower transmission pipe, a first control valve, a second control valve, and a damping bushing block. The damping bushing block is disposed inside the outer wall of the bushing shaft.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] A high-performance engine suspension damping bushing, compared with the prior art, allows the damping bushing block to work with the connecting frame and outer bushing on the outer wall after filling to provide torsional damping and protection.

[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] As attached Figure 1-4 As shown, this utility model provides a high-performance engine suspension damping bushing, including a connecting frame 1. The front end of the connecting frame 1 is provided with an engine suspension damping bushing auxiliary device 2. The engine suspension damping bushing auxiliary device 2 includes: a positioning component 21 and a damping knob replacement component 22. One end of the connecting frame 1 is provided on the outer side wall of the positioning component 21.

[0021] The positioning assembly 21 includes: an assembly screw 211, an assembly screw hole group 213, a positioning frame 212, a rotating adapter outer shaft 214, a rotating mounting groove 216, and an outer bushing 215. The inner side of the rotating adapter outer shaft 214 is provided at both ends of the outer bushing 215. The rotating mounting groove 216 is opened on the inner side of the rotating adapter outer shaft 214. One end of the positioning frame 212 is installed on the outer wall of the side of the rotating mounting groove 216. Two sets of positioning frames 212 and rotating mounting grooves 216 are provided. One end of the connecting frame 1 is installed on the outer wall of the outer bushing 215. The assembly screw hole group 213 is opened on the inner and outer walls of the positioning frame 212. The assembly screw 211 is detachably installed inside the assembly screw hole group 213.

[0022] The shock-absorbing knob replacement assembly 22 includes: an inlet / outlet slot 221, a bushing shaft 227, an upper transmission pipe 223, a lower transmission pipe 225, a first control valve 224, a second control valve 226, and a shock-absorbing bushing block 228. The shock-absorbing bushing block 228 is located inside the outer wall of the bushing shaft 227. The first control valve 224 is located at the lower end of the upper transmission pipe 223. The upper end of the lower transmission pipe 225 is installed at the lower end of the second control valve 226. Both ends of the bushing shaft 227 are respectively installed inside two sets of rotating adapter outer shafts 214. Two sets of inlet / outlet slots 221 are provided, and the two sets of inlet / outlet slots 221 are respectively opened at the upper and lower ends of the inner and outer walls of the outer bushing 215. One end of the upper transmission pipe 223 and the lower transmission pipe 225 are respectively installed at one end of the two sets of inlet / outlet slots 221. The two sets of inlet / outlet slots 221 are the same size.

[0023] The specific implementation method is as follows: When using this utility model, the first control valve 224 at the upper end of the upper transmission pipe 223 needs to be opened first, and the lower transmission pipe 225 at the lower end needs to be closed through the second control valve 226. After the second control valve 226 is closed, the shock-absorbing bushing block 228 can be filled through the upper transmission pipe 223. After the shock-absorbing bushing block 228 is filled, the outer wall of the bushing shaft 227 and the inside of the outer bushing 215 can be fixedly connected. After the shock-absorbing bushing block 228 is filled, it can be used in conjunction with the connecting frame 1 on the outer wall and the outer bushing 215. After the shock-absorbing bushing 228 has been used for a long time and its adhesion has been firmly reduced, the internal structure of the shock-absorbing bushing 228 can be disassembled by injecting decomposition liquid through the upper transmission pipe 223. The liquid is then discharged through the lower transmission pipe 225 and refilled for fixing. This device uses the upper transmission pipe 223 and the lower transmission pipe 225 to fill, disassemble and replace the shock-absorbing bushing 228, which reduces the installation difficulty of the shock-absorbing bushing 228 and further improves the stability and safety of the entire device.

[0024] The working principle of this utility model is as follows: When using this utility model, the first control valve 224 at the upper end of the upper transmission pipe 223 needs to be opened first, and the lower transmission pipe 225 at the lower end needs to be closed through the second control valve 226. After the second control valve 226 is closed, the shock-absorbing bushing block 228 can be filled through the upper transmission pipe 223. After the shock-absorbing bushing block 228 is filled, the outer wall of the bushing shaft 227 and the inside of the outer bushing 215 can be fixedly connected. After the shock-absorbing bushing block 228 is filled, it can cooperate with the connecting frame 1 on the outer wall and the outer bushing 215 to perform torsion shock absorption and protection. After the shock-absorbing bushing block 228 has been used for a long time and the adhesion has been firmly reduced, the decomposition liquid can be poured into the upper transmission pipe 223 to decompose the inside of the shock-absorbing bushing block 228, and then discharged through the lower transmission pipe 225. The bushing block is then refilled and fixed.
