Problems solved by technology

[0003] 1. The clearance fit between the circlip and the ball stud ensures that the ball stud will not be pulled out under the condition of installation force. However, in the vibration environment, the circlip contacts the ball stud, and the contact force is insufficient due to the smooth contact surface. It is easy to produce frictional noise between the spring and the ball stud
[0004] 2. There is no limit between the circlip and the ball joint, causing the circlip to shake and make abnormal noise in the ball joint in a vibration environment

Embodiment 1

[0024] The gas spring ball joint of the present invention includes a ball joint 1 , a ball stud 2 and a retaining spring 3 .

[0025] When the ball stud 2 is installed, push the circlip 3 to move upwards, and use the chute of the ball joint 1 to open the hook of the circlip 3 to enter into the ball socket. After being installed in place, the hook of the snap ring 3 clamps the ball neck portion of the ball stud 2 by elasticity. When the ball stud 2 moves downward, it drives the circlip 3 to move downward, but due to the inclined direction of the chute, when the upper part of the circlip 3 is supported by the ball socket, the hook will be blocked by the chute and cannot be opened further. , thereby preventing the ball head from continuing to move down, avoiding the ball joint 1 from falling out, and avoiding shaking at the same time.

[0026] In the present invention:

[0027] 1. The ball joint 1 has added ball joint grooves on the entire circlip mounting surface at any positi...

Abstract

The invention discloses an air spring ball socket connector which comprises a snap spring (3), wherein the snap spring (3) is of an arc structure, clamping hooks (32) are arranged at the two ends of the arc structure, and turnup corners (33) are arranged at the ends, far from the arc structure, of the clamping hooks (32). According to the air spring ball socket connector disclosed by the invention, the turnup corners are additionally arranged at the lower edges of clamping hooks of the snap spring, so that gaps between the clamping hooks and a ball neck are eliminated; meanwhile, a certain interference amount is kept, a ball head is prevented from shaking in a ball socket, and abnormal sound occurrence is eliminated.

Description

technical field [0001] The invention relates to a gas spring ball joint. Background technique [0002] see figure 1 As shown, the gas spring ball joint assembly (including the ball joint and the circlip) is currently installed with the ball studs: [0003] 1. The clearance fit between the circlip and the ball stud ensures that the ball stud will not be pulled out under the condition of installation force. However, in the vibration environment, the circlip contacts the ball stud, and the contact force is insufficient due to the smooth contact surface. Abnormal friction noise is likely to occur between the spring and the ball stud. [0004] 2. There is no limit between the circlip and the ball joint, causing the circlip to vibrate and make abnormal noise in the ball joint in a vibration environment. [0005] Therefore, a new gas spring ball joint is proposed to solve the above problems. Contents of the invention [0006] The object of the present invention is to provide ...
