[0002] The car stabilizer bar is an auxiliary elastic element in the car suspension. It is mainly used to prevent the car body from excessive lateral tilt when turning and to keep the car body balanced as much as possible. The purpose is to reduce the degree of lateral roll of the car and improve ride comfort.

[0003] There is a ball joint structure in the automobile stabilizer bar. Since the ball pin structure is a movable part in close contact, impurities entering the movable gap can easily cause the ball pin to wear and reduce the service life of the ball pin. For this reason, a dust cover is used to protect the ball pin. However, the existing dust cover fixes the dust cover with a clamping ring. When the dust cover is accidentally damaged, the setting of the clamping ring brings inconvenience to the installation and removal of the dust cover, reduces the assembly of the dust cover, and reduces the care and maintenance of the ball pin structure. In addition, the clamping ring is easily damaged during the disassembly and assembly process.

[0004] For example, the automobile stabilizer bar with application number 201821271220.8 includes a rod-shaped body with ball joint structures at both ends of the body. The ball joint structure includes a dust cover, a ball pin and a ball seat. The outer wall of the ball seat near the top has a circle of annular groove. The lower end of the dust cover is embedded in the annular groove through a clamp ring, and the upper end of the dust cover is embedded in the annular groove through a clamp. The ball bowl is divided into an outer ball bowl and an inner ball bowl, which can effectively solve the problems of lubricating grease leakage and looseness and abnormal noise.

[0005] In the above patent, the dust cover is still fixed by a clamp ring and a clamp, which is not convenient for assembling, disassembling and replacing the dust cover, and also increases the trouble of maintaining and preserving the ball pin. Utility Model Content

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 4 As shown, the utility model can be implemented through the following embodiments: an applicable automobile stabilizer bar, including a main body 1, ball seats 11 are opened at both ends of the main body 1, a ball stud 2 is installed in the ball seat 11, the ball stud 2 is covered with a dust cover 3, a tightening part 1 31 and a tightening part 2 32 are arranged on the dust cover 3, a ball bowl 4 is arranged between the ball stud 2 and the ball seat 11, a sealing plate 5 is installed under the ball bowl 4, a mounting groove 21 is opened on the ball stud 2, a limiting part 22 is arranged on the upper end of the mounting groove 21, the tightening part 1 31 is installed in the mounting groove 21, and the tightening part 2 32 is installed outside the ball seat 11.

[0023] The tightening part 1 31 and the tightening part 2 32 on the dust cover 3 can be tightened on the ball stud 2 by themselves to prevent dust from entering the ball stud 2. The tightening part 1 31 is tightened in the installation groove 21, so that the groove wall becomes a part of blocking dust and improving the sealing performance.

[0024] like Figure 2 and Figure 4 As shown, the tightening portion 31 is provided with an extension portion 311, and the extension portion 311 wraps the limiting portion 22. The setting of the extension portion 311 in contact with the limiting portion 22 improves the sealing performance of the dust cover 3, and the setting of the extension portion 311 enables the extension portion 311 to move under the influence of the limiting portion 22 when the ball stud 2 moves, thereby driving the dust cover 3 to move, thereby preventing the dust cover 3 from friction with the limiting portion 22, which may cause the sealing performance to decrease.

[0025] like Figure 2 and Figure 4 As shown, a plurality of grooves 312 are provided on the inner surface of the tightening part 31. The grooves 312 provide a certain deformation space for the tightening part 31 when the ball pin 2 moves, thereby preventing the tightening part 31 from excessively deforming and causing a gap to appear, thereby reducing the sealing performance. The grooves 312 are also provided to facilitate accommodating trace impurities, thereby preventing the impurities from rubbing against the dust cover 3 and causing damage to the dust cover 3.

[0026] like Figure 1 and Figure 3 As shown, the cross section of the main body 1 is a cross. The cross section provides strong bending strength to prevent the stabilizer bar from deforming after being stressed. At the same time, compared with a cylinder with the same diameter, the cross section is lighter and has a lower production cost.

[0027] like Figure 1 As shown, the main body 1 is provided with reinforcing ribs 12 and reinforcing blocks 13. The reinforcing ribs 12 and reinforcing blocks 13 are used to strengthen the strength of the main body 1 to prevent the main body 1 from being damaged due to excessive stress locally.

[0028] like Figure 2 and Figure 4 As shown, a tightening ring 6 is installed in the tightening part 32, and the tightening ring 6 is "J" shaped and made of metal. The tightening ring 6 is used to improve the tightening strength of the tightening part 32 and strengthen the strength of the tightening part 32; the "J" shape provides elasticity for the tightening ring 6, strengthens the sealing of the tightening ring 6, and at the same time, the dust cover 3 buried in the tightening part 32 is less affected by the outside world and is not easily damaged.

[0029] like Figure 2 and Figure 5 As shown, an annular groove 41 is provided in the ball bowl 4. The annular groove 41 is used to store grease, thereby reducing the number of times the grease is replenished, thereby reducing the frequency of maintaining and servicing the ball stud 2.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0031] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
