Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, and specifically relates to a novel stabilizer bar bushing. BACKGROUND

[0002] The stabilizer bar bushing is used to improve the stability of automobile driving and riding, thereby enhancing the smoothness of driving, making the driver safer when driving, and effectively reducing the body vibration and absorbing the noise of the suspension system.

[0003] The stabilizer bar bushing is prepared by bonding the framework and rubber together through vulcanization, coating adhesive on the framework, and then placing it in a rubber mold to be made through high temperature and high pressure vulcanization process. However, the manufacturing cost is high, and the biggest potential hidden danger after the framework and rubber are vulcanized is that it is difficult to identify the delamination problem of the framework and rubber. At the same time, the framework on the market is basically enveloped in rubber, and it is also difficult to identify the bonding problem of this kind of bushing through traditional destructive experiments. SUMMARY

[0004] The utility model discloses a novel stabilizer bar bushing which solves the problems in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] The novel stabilizer bar bushing comprises:

[0007] a bushing framework, a bushing rubber lower part and a bushing rubber upper part;

[0008] The upper end of the bushing framework is bonded to the bushing rubber lower part by glue, the upper end of the bushing framework is fixedly connected with a plurality of first firm rods, the lower end of the bushing rubber lower part is provided with a plurality of first grooves corresponding to the plurality of first firm rods, the upper end of the bushing rubber upper part is fixedly connected with a plurality of second firm rods, and the upper end of the bushing rubber lower part is provided with a plurality of second grooves corresponding to the plurality of second firm rods.

[0009] Preferably, the side walls of the bushing rubber lower part and the bushing rubber upper part that are close to each other are provided with mounting grooves, and the inner walls of the mounting grooves are fixedly connected with a plurality of rubber ribs.

[0010] Preferably, the bushing framework is embedded with two reinforcing ribs.

[0011] Preferably, the side wall of the bushing framework is provided with two mounting holes.

[0012] The utility model has the following beneficial effects:

[0013] 1. By bonding the upper end of the bushing skeleton and the lower part of the bushing rubber with adhesive, the existing technology of bonding the skeleton and rubber together by vulcanization is avoided. This not only reduces the manufacturing cost of the stabilizer bar bushing, but also reduces the phenomenon of poor vulcanization bonding between rubber and skeleton, avoiding the potential risk of delamination.

[0014] 2. Adding two reinforcing ribs can increase the strength of the bushing frame. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 The new stabilizer bar bushing includes a bushing skeleton 1, a lower bushing rubber component 2, and an upper bushing rubber component 3. The upper end of the bushing skeleton 1 and the lower bushing rubber component 2 are bonded together with adhesive, which avoids the vulcanization method used in the prior art to bond the skeleton and rubber together. This not only reduces the manufacturing cost of the stabilizer bar bushing, but also reduces the phenomenon of poor vulcanization bonding between rubber and skeleton, avoiding the potential risk of delamination.

[0022] The upper end of the bushing frame 1 is fixedly connected with multiple first fixing rods 4, and the lower end of the bushing rubber lower component 2 is provided with multiple first grooves 5 corresponding one-to-one with the multiple first fixing rods 4 (e.g., Figure 3As shown), a plurality of second secure rods 6 are fixedly connected to the lower end of the upper bush rubber part 3, and a plurality of second grooves 7 corresponding to the plurality of second secure rods 6 are formed in the upper end of the lower bush rubber part 2 (as shown Figure 2

[0023] The plurality of first secure rods 4 and the plurality of second secure rods 6 make the installation between the bush skeleton 1 and the lower bush rubber part 2 more compact, and the installation between the lower bush rubber part 2 and the upper bush rubber part 3 more compact, thereby improving the stability of the entire stabilizer bush.

[0024] The side walls of the lower bush rubber part 2 and the upper bush rubber part 3 that are close to each other are provided with installation grooves, and a plurality of rubber ribs 8 are fixedly connected to the inner walls of the installation grooves, so that when the external stabilizer is installed between the lower bush rubber part 2 and the upper bush rubber part 3, the plurality of rubber ribs 8 are in contact with the external stabilizer, thereby increasing the stability of the installed external stabilizer.

[0025] The bush skeleton 1 is embedded with two reinforcing ribs 9, thereby increasing the use strength of the bush skeleton 1, and the side walls of the bush skeleton 1 are provided with two installation holes 10.

[0026] In the production of the stabilizer bush, the upper end of the bush skeleton 1 and the lower bush rubber part 2 that has been injection molded are bonded by glue, thereby avoiding the bonding of the skeleton and the rubber together by vulcanization in the prior art, which not only reduces the manufacturing cost of the stabilizer bush, but also reduces the phenomenon of poor bonding of the rubber and the skeleton by vulcanization, thereby avoiding potential risks of delamination, and the plurality of first secure rods 4 and the plurality of first grooves 5 make the installation between the bush skeleton 1 and the lower bush rubber part 2 more compact, and the plurality of second secure rods 6 and the plurality of second grooves 7 make the installation between the lower bush rubber part 2 and the upper bush rubber part 3 more compact.

[0027] Meanwhile, the two reinforcing ribs 9 provided in the bush skeleton 1 during the production of the bush skeleton 1 can increase the use strength of the bush skeleton 1.

[0028] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.​
