Description

Technical Field

[0001] This utility model relates to the field of automotive bushing technology, and in particular to vehicle stabilizer bar bushings. Background Technology

[0002] During vehicle operation, the stabilizer bar plays a crucial role, effectively reducing body roll during cornering and improving handling stability and driving safety. The stabilizer bar bushing, as the connecting component between the stabilizer bar and the vehicle body, not only supports and secures the stabilizer bar but also possesses excellent shock absorption, noise reduction, and wear resistance.

[0003] However, existing vehicle stabilizer bar bushings have some shortcomings. Stabilizer bar bushings are usually made of a single rubber material. Although rubber has a certain elasticity and shock absorption performance, it is easily affected by vibration, impact and friction generated during vehicle operation during long-term use, resulting in severe wear of the bushing. This, in turn, affects the normal operation of the stabilizer bar, reduces the vehicle's handling performance and ride comfort. At the same time, traditional bushings have poor sealing performance, which makes it easy for dust, moisture and other impurities to enter the bushing, accelerating the aging and damage of the bushing. Therefore, vehicle stabilizer bar bushings are needed. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle stabilizer bar bushing that solves the problems of severe wear and easy aging of bushings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle stabilizer bar bushing, comprising:

[0006] The outer rubber sleeve has an annular protrusion on its outer wall and outwardly folded lips at its upper and lower ends.

[0007] An inner wear-resistant layer is provided, which is closely attached to the interior of the outer rubber sleeve;

[0008] An intermediate buffer layer is disposed between the outer rubber sleeve and the inner wear-resistant layer.

[0009] Preferably, the outer rubber sleeve is made of EPDM rubber.

[0010] Preferably, the inner wear-resistant layer is made of polytetrafluoroethylene (PTFE).

[0011] Preferably, the intermediate buffer layer is made of porous rubber material.

[0012] Preferably, the end face of the lip is provided with an annular groove, the annular groove of the lip is provided with a fitting sealing ring, and the inner wall of the inner wear-resistant layer is provided with a sealing rubber ring.

[0013] Preferably, two sets of sealing rings are provided, and the two sets of sealing rings are respectively provided at the upper and lower ends of the inner wall of the inner wear-resistant layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The inner wear-resistant layer effectively reduces the coefficient of friction between the stabilizer bar and the bushing, improving the wear resistance of the bushing. The porous rubber buffer layer in the middle can better absorb vibration and impact energy, improving the ride comfort of the vehicle. The lip, sealing ring and sealing rubber ring enhance the sealing performance of the bushing and prevent external impurities from entering. Attached Figure Description

[0021] 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.

[0022] This utility model relates to vehicle stabilizer bar bushings, such as... Figure 1-4As shown, the device includes an outer rubber sleeve 1 made of EPDM rubber. The inner wall of the outer rubber sleeve 1 has an inner wear-resistant layer 2 made of polytetrafluoroethylene (PTFE). PTFE has an extremely low coefficient of friction and excellent wear resistance, effectively reducing friction between the stabilizer bar and the bushing, thus reducing wear. The inner surface of the inner wear-resistant layer 2 is smooth and flat, making full contact with the stabilizer bar surface, ensuring the stabilizer bar can rotate flexibly within the bushing. The inner wear-resistant layer 2 is tightly attached to the inside of the outer rubber sleeve 1. An intermediate buffer layer 3 is provided between the outer rubber sleeve 1 and the inner wear-resistant layer 2. The intermediate buffer layer 3 is made of porous rubber material, which has good elasticity and energy absorption properties, effectively absorbing vibration and impact energy generated during vehicle operation, reducing the impact on the stabilizer bar and vehicle body. The porous structure of the intermediate buffer layer can deform under stress, playing a role in buffering and shock absorption, while also increasing the flexibility of the bushing. The outer wall of the outer rubber sleeve 1 is provided with an outer rubber sleeve 1, which is made of EPDM rubber. The inner wall of the outer rubber sleeve 1 is provided with an inner wear-resistant layer 2, which is made of polytetrafluoroethylene (PTFE). PTFE has an extremely low coefficient of friction and excellent wear resistance, which can effectively reduce the friction between the stabilizer bar and the bushing and reduce the degree of wear. The inner surface of the inner wear-resistant layer 2 is smooth and flat, making full contact with the surface of the stabilizer bar, ensuring that the stabilizer bar can rotate flexibly within the bushing. The inner wear-resistant layer 2 is tightly attached to the inside of the outer rubber sleeve 1. An intermediate buffer layer 3 is provided between the outer rubber sleeve 1 and the inner wear-resistant layer 2. The intermediate buffer layer 3 is made of porous rubber material. Porous rubber material has good elasticity and energy absorption properties, which can effectively absorb the vibration and impact energy generated during vehicle operation, reducing the impact on the stabilizer bar and the vehicle body.The porous structure of the intermediate buffer layer 3 allows it to deform under stress, providing cushioning and shock absorption while also increasing the bushing's flexibility. The outer wall of the outer rubber sleeve 1 has annular protrusions 7, increasing friction between the outer rubber sleeve 1 and the vehicle body mounting area, ensuring a secure and stable installation. Lips 4 are fixedly connected to both ends of the outer rubber sleeve 1, providing a tight seal against the vehicle body mounting surface and preventing dust and moisture from entering the bushing. An annular groove is formed on the end face of the lip 4, and a sealing ring 5 is wedged into the groove, further enhancing the bushing's sealing performance. Two sets of sealing rings 6 are provided on the inner wall of the inner wear-resistant layer 2, with each set positioned on a separate part of the inner wear-resistant layer. The inner wall of the wear layer 2 has annular protrusions 7 at the top and bottom to prevent dust, moisture and other impurities from entering the bushing from the side. These protrusions increase the friction between the outer rubber sleeve 1 and the vehicle body mounting area, ensuring the bushing is firmly installed and not easily loosened. The two ends of the outer rubber sleeve 1 are fixedly connected with lips 4, which fit tightly against the vehicle body mounting surface, providing a preliminary seal to prevent dust and moisture from entering the bushing. The end face of the lip 4 has an annular groove, and a sealing ring 5 is wedged into the annular groove of the lip 4 to further enhance the sealing performance of the bushing. The inner wall of the inner wear-resistant layer 2 is provided with sealing rubber rings 6. Two sets of sealing rubber rings 6 are provided, one at the top and one at the bottom of the inner wall of the inner wear-resistant layer 2, to prevent dust, moisture and other impurities from entering the bushing from the side.

[0023] Working principle: The stabilizer bar will swing and twist accordingly with the vehicle's turning and bumping movements. The relative movement between the stabilizer bar and the bushing is smoothly achieved through the low friction characteristics of the inner wear-resistant layer 2, reducing friction loss. The middle buffer layer 3 absorbs the vibration and impact energy generated during the movement of the stabilizer bar, protecting the stabilizer bar and the vehicle body structure. The annular protrusion 7 and lip 4 of the outer rubber sleeve 1, as well as the sealing structure, work together to effectively prevent external impurities from entering the bushing, ensuring the normal working environment of the bushing and extending its service life.
