Description

Technical Field

[0001] This utility model relates to the field of stabilizer bar bushing technology, and in particular to a low torsional stiffness lateral stabilizer bar bushing. Background Technology

[0002] The stabilizer bar bushing mainly consists of the stabilizer bar body and the bushing. The stabilizer bar body is designed primarily to avoid motion interference with the suspension's guide rod system, while also stabilizing the suspension. The bushing is located at the connection point between the stabilizer bar and the wheel and chassis, serving to dampen vibrations and reduce noise.

[0003] However, when using existing low torsional stiffness lateral stabilizer bar bushings, the stabilizer bar twists inside the bushing, causing the wear level in the middle of the bushing to differ from that in other parts. The wear level in the middle is higher, and the bushing cannot be used due to excessive wear in the middle, so it cannot support long-term use. Therefore, a low torsional stiffness lateral stabilizer bar bushing is needed. Utility Model Content

[0004] The purpose of this invention is to provide a low torsional stiffness lateral stabilizer bar bushing, which solves the problem that the wear degree in the middle of the bushing is different from that in other parts, the wear degree in the middle is high, and the bushing cannot be used due to excessive wear in the middle, thus failing to support long-term use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low torsional stiffness lateral stabilizer bar bushing, including a main bushing, wherein the main bushing has an inner wear-resistant body that surrounds the inner wall of the main bushing, and a bushing component that cooperates with the inner wear-resistant body on the outer side of the main bushing. The bushing component includes a side bushing, and the periphery of the side bushing has a vertical groove for compression and extending along the axial direction of the side bushing. The periphery of the side bushing has a groove perpendicular to the extension direction of the vertical groove for receiving lateral pressure.

[0006] Preferably, the vertical groove is arranged in a ring around the periphery of the side bushing.

[0007] Preferably, the tank includes: a second sidewall and a third sidewall disposed opposite to each other, and a first sidewall for connecting the second sidewall and the third sidewall.

[0008] Preferably, the first sidewall is provided with an outer wear-resistant body that is fixedly connected around its outer wall.

[0009] Preferably, the bushing components are symmetrically arranged on both sides of the main bushing.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By fitting the bushing onto the equipment connection, when the stabilizer bar rotates, it will first rub against the inner wear-resistant body fixedly connected to the inner wall of the main bushing. At the same time, the outer side will rub against the bushing component with a trumpet-shaped structure. When the inner wear-resistant body and the bushing component wear to a certain extent, they will rub against the main bushing and the bushing component. During the friction, the vertical grooves and slots will provide the bushing with a certain degree of deformation-bearing force, preventing the bushing from undergoing minor deformation that would lead to increased wear later. After the bushing component wears out, the outer wear-resistant body will support the friction, further increasing the service life of the bushing. Attached Figure Description

[0018] 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.

[0019] This utility model relates to a low torsional stiffness lateral stabilizer bar bushing, such as... Figure 1-5As shown, it includes a main bushing 1, a bushing component 3 connected to the side of the main bushing 1, an inner wear-resistant body 2 fixed around the center of the inner wall of the main bushing 1 to improve the wear resistance in the middle and prevent excessive wear, a bushing component 3 fixedly connected to the side of the main bushing 1, the bushing component 3 being symmetrically arranged on both sides of the main bushing 1 to bear pressure, and an outer ring 4 fixedly connected to the side of the bushing component 3 away from the main bushing 1.

[0020] Furthermore, such as Figure 3 As shown, the bushing component 3 includes a side bushing 31. The outer wall of the side bushing 31 has a vertical groove 32 along the axial direction of the side bushing 31. The outer wall of the side bushing 31 has a groove 33 perpendicular to the vertical groove 32 and located on the circumference of the side bushing 31. Inside the groove 33, there is an outer wear-resistant body 34 fixedly connected in a ring. The vertical groove 32 is arranged in a ring perpendicular to the groove 33 on the circumference of the side bushing 31 to increase the shrinkage space when the bushing is subjected to lateral pressure. The outer wear-resistant body 34 is symmetrically arranged on both sides of the main bushing 1 about the inner wear-resistant body 2. The bushing component 3 has a trumpet-shaped structure. After the inner wear-resistant body 2 is worn due to the force on the main bushing 1, the bushing component 3 can reduce the force on the outside of the main bushing 1 and increase the wear resistance of the bushing.

[0021] Among them, such as Figure 4 As shown, the groove 33 includes: a second sidewall 332 and a third sidewall 333 disposed opposite to each other, and a first sidewall 331 for connecting the second sidewall 332 and the third sidewall 333, for improving the pressure resistance of the bushing and providing space for pressure deformation.

[0022] In practical use: By fitting the bushing onto the equipment connection, when the stabilizer rod rotates, it will first rub against the inner wear-resistant body 2, which is fixedly connected to the inner wall of the main bushing 1. At the same time, the outer side will rub against the bushing component 3, which has a trumpet-shaped structure. When the inner wear-resistant body 2 and the bushing component 3 are worn to a certain extent, they will rub against the main bushing 1 and the bushing component 3. During the friction, the vertical groove 32 and the groove 33 will provide the bushing with a certain degree of deformation-bearing force, preventing the bushing from undergoing minor deformation that would lead to increased wear later. After the bushing component 3 is worn, the outer wear-resistant body 34 will support the friction, further increasing the service life of the bushing.
