[0002] For a conventional rubber bushing, the bushing body is first press-fitted with the smooth rod of the stabilizer bar, and then the bushing body is press-fitted with the bracket. Two press-fittings are required, resulting in low production efficiency, poor process stability, high demand for process control ability, and high dimensional tolerance requirements for the rubber bushing and the bracket. Moreover, the components are combined together by interference fitting. When the external limiting structure and load disappear, the interference fit amount of the stabilizer bar assembly disappears, and the components will separate from each other. Summary of the Utility Model

[0003] The main technical problem to be solved by the utility model is to provide an automobile stabilizer bar bushing, which can reduce the production process, lower the production difficulty, and prevent the components of the bushing from separating in the free state.

[0004] To solve the above technical problem, one technical solution adopted by the utility model is: to provide an automobile stabilizer bar bushing, including: a bushing body and a bracket. The bushing body is provided with an inner hole for the stabilizer bar to pass through. A first glue layer is coated on the surface of the inner hole of the bushing body, and a second glue layer is coated on the outer surface of the bushing body. The bracket and the bushing body are vulcanized and bonded through the second glue layer, and the bushing body and the stabilizer bar are vulcanized and bonded through the first glue layer.

[0005] Preferably, a first limiting protrusion extends from the bushing body towards the bracket, and a first limiting ring is arranged on the bracket and is matched with the first limiting protrusion. A first limiting groove is formed on one side of the first limiting ring close to the first limiting protrusion.

[0006] Preferably, a skeleton assembly for supporting the bushing body is arranged inside the bushing body. The skeleton assembly includes an upper inserting piece, a lower inserting piece and a base. The upper inserting piece and the lower inserting piece are oppositely distributed inside the bushing body, and the base is arranged on the side of the lower inserting piece away from the upper inserting piece.

[0007] Preferably, clamping ears are arranged on both sides of the base, and clamping holes are formed on both sides of the bracket. The clamping ears extend to both sides of the bushing body and are clamped and matched with the clamping holes.

[0008] Preferably, filling holes are formed on the upper inserting piece and / or the lower inserting piece and / or the base.

[0009] Preferably, reinforcing ribs that intersect with each other are arranged at the bottom of the base.

[0011] Preferably, the raised patterns are wavy or convex dot-shaped.

[0012] Preferably, the bracket is made of high-strength plastic material.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. By vulcanizing the connection between the stabilizer bar, the bushing body and the bracket, the stabilizer bar assembly is an integral structure in the free state, ensuring the stability of the product state during storage, handling and transportation, and avoiding the problem that in the traditional method, various sub-parts are combined through an interference fit design, but during storage, handling and transportation, the interference amount may become smaller and fall off due to factors such as bumps and vibrations, causing complaints from the client.

[0015] 2. Avoid the problem of generating noise when the stabilizer bar assembly is subjected to an external load due to the relative sliding between the bushing body and the bracket or the appearance of a gap between the two.

[0016] 3. The lower interference amount design and the conventional outer shape structure also reduce the difficulty of the preliminary design; at the same time, they also reduce the requirements for production equipment and production processes, improve production efficiency, and reduce production costs.

[0030] Embodiment:

[0031] Reference Figures 1 - 4 , an anti-roll bar bushing for an automobile, comprising: a bushing body 1 and a bracket 2. The bushing body 1 is provided with an inner hole 14 for the anti-roll bar to pass through. A first glue layer 3 is coated on the surface of the inner hole 14 of the bushing body 1, and a second glue layer 4 is coated on the outer surface of the bushing body 1. The bracket 2 and the bushing body 1 are vulcanized and bonded through the second glue layer 4, and the bushing body 1 and the anti-roll bar are vulcanized and bonded through the first glue layer 3, thereby integrating the anti-roll bar, the bushing body 1 and the bracket 2 into a whole. Even under the influence of factors such as bumps and vibrations during storage, handling and transportation, the problem of detachment will not occur, and it is avoided that when the anti-roll bar assembly is subjected to an external load, noise is generated due to the relative sliding between the bushing body 1 and the bracket 2 or the appearance of a gap between the two, and the entry of foreign matters such as water, dust and sand between the bushing body and the bracket 2. Both the first glue layer 3 and the second glue layer 4 can be rubber adhesives. The bracket 2 is made of high-strength plastic material, thereby reducing the weight of the anti-roll bar assembly and making the vehicle more lightweight.

[0032] Reference Figures 1 - 4, a first limiting protrusion 5 extends towards the bracket 2 on the bushing body 1, a first limiting ring 6 that cooperates with the first limiting protrusion 5 extends on the bracket 2, a first limiting groove 7 is formed on one side of the first limiting ring 6 close to the first limiting protrusion 5, and the first limiting protrusion 5 cooperates with the first limiting groove 7, thereby increasing the contact area between the bushing body and the bracket 2, playing an axial limiting role on the bushing body 1, and also increasing the support strength.

[0033] Reference Figures 1 - 4 , in order to increase the stiffness of the bushing body 1, a skeleton assembly for supporting the bushing body 1 is wrapped inside the bushing body 1. The skeleton assembly includes an upper insert piece 8, a lower insert piece 9 and a base 10. The upper insert piece 8 and the lower insert piece 9 are distributed relatively inside the bushing body 1, and the base 10 is arranged on the side of the lower insert piece 9 away from the upper insert piece 8, that is, arranged at the bottom inside the bushing body 1. The upper insert piece 8, the lower insert piece 9 and the base 10 are made of hard materials such as metal. Filling holes 15 are formed on the upper insert piece 8 and / or the lower insert piece 9 and / or the base 10, thereby accelerating the flow of rubber during injection molding through the filling holes 15, so that the bushing body 1 is molded faster and is more stable when heated. In order to increase the support strength of the base 10, reinforcing ribs that cross each other extend from the bottom of the base 10.

[0034] Reference Figures 1 - 4 , in order to further stabilize the positional relationship between the bushing body 1 and the bracket 2 and be able to withstand greater forces, ear pieces 11 are integrally formed on both sides of the base 10, and engaging holes 12 are formed on both sides of the bracket 2. The ear pieces 11 extend to both sides of the bushing body 1 and are engaged with the engaging holes 12. The ear pieces 11 adopt a flexible deformation structure to ensure that the ear pieces 11 are deformed smoothly during press-fitting so as to enter the engaging holes 12 of the bracket 2. Through the connection between the ear pieces 11 and the bracket 2, the connection strength between the bushing body 1 and the bracket 2 is further increased.

[0035] Reference Figures 1 - 4 , in order to further increase the contact area, friction and strengthen the bonding effect between the bushing body and the bracket 2, raised patterns 13 are distributed on the outer surface of one side of the bushing body 1 close to the bracket 2. The raised patterns 13 are in a wavy shape or convex dot shape or triangular shape, thereby increasing the contact area and friction between the bushing body and the bracket 2, and by increasing the raised patterns 13, the bushing body is not so smooth, so as to be able to strengthen the bonding effect between the bushing body and the bracket 2 and make the bonding between the bushing body and the bracket 2 more firm.

[0036] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
