Abstract

The present invention prevents the grease filled between the ball stud and the ball seat from leaking to the outside, so that the grease can always perform smooth lubrication between the ball stud and the ball seat, and even if the dust cover is broken. It provides a ball joint structure that prevents foreign matter from penetrating between the ball stud and the ball seat, and ensures stable performance of the ball joint continuously, thereby improving its durability.

Description

Ball Joint Structure

The present invention relates to a ball joint structure, and more particularly, to a technology for improving the utilization and durability of the ball joint by improving the utilization of the grease responsible for lubrication inside the ball joint.

1 is a view illustrating a ball joint 500 used in a conventional vehicle suspension device, and is connected to allow a free refraction movement between the knuckle 502 and the suspension arm 504.

2 is a cross-sectional view showing the internal structure of the conventional ball joint 500 as described above, the ball seat 508 is interposed between the socket 506 and the ball stud 508, the ball stud 508 It is to surround the spherical portion of, the ball seat 510 is inserted into the socket 506 is fixed to the plug, the dust cover 512 is wrapped around the outside so that foreign matter does not penetrate. .

In addition, grease is injected between the ball stud 508 and the ball seat 510 so that lubrication is performed during relative movement between the ball studs 508 and the ball seat 510. In many cases, it is pushed out of the seat 510, in which case the lubrication between the ball stud 508 and the ball seat 510 is not sufficient, noise is generated due to friction, or durability is reduced.

Meanwhile, the dust cover 512 has a function of preventing foreign matter from penetrating from the outside as described above and preventing grease from leaking to the outside, but the dust cover 512 may be damaged. It is also possible to prevent the grease from leaking to the outside, but leaking outside the ball seat 510 and the ball joint 500 in the dust cover 512, as shown in FIG.

The present invention prevents the grease filled between the ball stud and the ball seat from leaking to the outside, so that the grease can always perform smooth lubrication between the ball stud and the ball seat, and even if the dust cover is broken. The object of the present invention is to provide a ball joint structure that prevents foreign matter from penetrating between the ball stud and the ball seat, and to ensure a stable performance of the ball joint, thereby improving its durability.

Ball joint structure of the present invention for achieving the object as described above

In the ball joint structure in which a ball sheet is coupled to a sphere of a ball stud and inserted into a socket,

The plug is inserted into the socket to restrain the ball sheet to the socket, and comprises a plug integrally provided with a sealing member in close contact with the ball stud.

The present invention prevents the grease filled between the ball stud and the ball seat from leaking to the outside, so that the grease can always perform smooth lubrication between the ball stud and the ball seat, and even if the dust cover is broken. Prevent foreign matter from penetrating between the ball stud and the ball seat, and ensure the stable performance of the ball joint continuously to improve its durability.

Referring to FIG. 3, in the embodiment of the present invention, the ball seat 3 is coupled to the spherical portion of the ball stud 1 and inserted into the socket 5, and the plug 7 is inserted into the socket 5. The ball seat 3 is constrained to the socket 5, but the sealing member 9 is in close contact with the ball stud (1).

That is, in the present invention, foreign matter from the outside is prevented from entering between the ball seat 3 and the ball stud 1 only by the dust cover, and the grease is prevented from flowing out. Through the sealing member (9) provided in 7) it is to be made one more step sealing.

The sealing member 9 of the plug 7 is made of rubber, and is vulcanized (VULCANIZATION) on the inner circumferential surface of the plug 7. That is, the rubber is configured to be in contact with the ball stud 1 with elasticity.

The sealing member 9 is formed in a cross-sectional shape that gradually narrows toward the ball stud 1 from a portion bonded to the inner circumferential surface of the plug 7, and the plug 7 is seated on the socket 5. In this state, the leading end of the sealing member 9 is formed to be pressed to the spherical portion of the ball stud (1).

Referring to FIG. 3, the left side shows the state when the plug 7 is started to be assembled to the socket 5, and the right side compares and shows the completed state.

That is, by inserting the plug (7) with the sealing member (9) into the socket (5) and fixed by plastic deformation of the finishing portion of the socket (5), the ball stud (1) and the ball seat ( If 3) is not separated from the socket 5, the tip of the sealing member 9 is in close contact as shown in the spherical portion of the ball stud 1, even when the dust cover is broken. In addition to preventing foreign matter from passing through the sealing member 9 between the ball stud 1 and the ball seat 3, the grease between the ball stud 1 and the ball seat 3 is retained only therein. It is to prevent the outflow to the outside, so that a stable lubrication is always performed.

As described above, when the sealing member 9 provided in the plug 7 blocks the leakage of the grease, smooth operation of the ball joint is continuously ensured and its durability is greatly improved.

1 is a view illustrating a state in which a conventional ball joint is mounted as a part of a vehicle suspension;

2 is a cross-sectional view illustrating a structure of a conventional ball joint;

3 is a view illustrating a ball joint structure of the present invention.
