Description

Apparatus for fixing ball stud in automobile}

The present invention relates to a ball stud assembly for a vehicle, and more particularly to a ball stud assembly for a vehicle for the structure of the ball stud mounted to the staff bar by a link.

In general, the suspension device of the vehicle is connected to the axle of the vehicle so that the vibration or shock received from the road surface while the vehicle is running is not directly transmitted to the vehicle body, thereby preventing damage to the vehicle body, passengers, cargo, etc., and improving the ride comfort. . The suspension system is composed of a chassis spring to alleviate the impact from the road surface, a shock absorber to control the free vibration of the chassis spring to improve ride comfort, and a staff bar to prevent rolling of the vehicle. Among these, the staff bar maintains the equilibrium by reducing the inclination of the vehicle body by the elastic force generated when the staff bar is twisted when the left and right wheels of the vehicle move up and down, respectively. As a conventional step bar link structure which is usually mounted on a control arm, there is one disclosed in Japanese Patent Laid-Open No. 1997-0074050.

1 and 2, a link for coupling a control arm, comprising: a step bar 1; The step bar 1 includes a fastening part 1a formed by fastening an end thereof and having a fastening hole, and a ball stud 2 mounted to the fastening part 1a;

The head of the ball stud (2) is formed with a rotary hole (2a), the body portion (2b) is formed so that the screw groove is formed and tightened by the nut (4).

In this way, the ball stud 2 formed is fastened to the rotating part 3a formed in the step bar link 3, and is operated, thereby improving the ride comfort of the vehicle.

However, the above-described step bar link structure is formed in the end of the step bar to form a fastening portion formed in the end of the ball bar after passing through the trim and punching process after the compression and punching process to form a fastening hole through which the ball stud passes through the ball Since the studs are connected by tightening and tightening the nut, there is a problem in that the number of related parts increases and work efficiency is reduced.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to provide a ball stud assembly device for a vehicle that can improve the productivity and work efficiency as well as reduce the production cost by improving the staff bar link structure. There is this.

Vehicle ball stud assembly according to the present invention for solving the above problems is a step bar with a hollow formed at both ends; A step bar link connected to the step bar and being rotated; A ball stud disposed between the step bar link and the step bar, the ball stud being formed to rotate the step bar link; An end portion of the ball stud is configured to include a fixing portion to be fixed to be inserted into a hollow formed in the step bar.

The fixing portion is formed so that the outer width of the end of the body portion is large, the width becomes smaller toward the spherical head of the ball stud.

The body portion of the ball stud is formed with a larger one of the width of the upper, lower, left and right toward the end.

The outer width of the fixing part is any one of the width of the upper, lower, left and right is large, the outer width of the fixing portion is formed smaller than the hollow diameter formed on the step bar.

When the step bar is molded in the state where the ball stud is inserted, the end of the step bar is formed to have a diameter smaller than the width of the fixing part of the ball stud and is fixed integrally.

The ball stud assembly device for a vehicle according to the present invention configured as described above reduces the step bar trim and punching process by integrally modularizing the ball stud to the step bar, and the assembly process of fastening the step bar and the step bar link is simple, thereby improving work efficiency. In addition, the weight is reduced and the cost is reduced by reducing the number of related parts.

        Hereinafter, with reference to the accompanying drawings, a ball stud assembly for a vehicle according to an embodiment of the present invention will be described in detail. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms, and only the embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you.

Figure 3 is a perspective view showing a state before assembly of the vehicle ball stud assembly apparatus according to the present invention, Figure 4 is a perspective view showing a state after the assembly of the vehicle ball stud assembly according to the present invention, Figure 5 is a vehicle according to the present invention A perspective view showing a state in which a step bar link and a step bar are mounted by a ball stud assembly device, and FIG. 6 is a cross-sectional view of AA according to FIG. 5.

Ball stud assembly device for a vehicle according to the present invention has a step bar 10 is formed at both ends of the hollow bar, the step bar link 30 is connected to the step bar 10, the step bar link 30 and The ball stud 20 is disposed between the step bar 10 and the rotary ball 21 is formed so that the step bar link 30 can rotate, and the end of the ball stud 20 is the step bar 10 It is configured to include a fixing part 24 is fixed to be inserted into the hollow portion 12 formed in the integrated.

The step bar 10 mounted to a control arm (not shown) by a link has hollow portions 12 formed at both ends thereof.

The ball stud 20 is inserted into the hollow part 12 formed in the step bar 10, and the ball stud 20 has a spherical rotary ball in the head so that the step bar link 30 can rotate. 21 is formed.

The rotary sphere 21 is coupled to the rotary unit 31 formed on the step bar link (30).

The rotating part 31 is integrally formed at the end of the step bar link 30 so that the rotating tool 21 is mounted through an opening having the rotating spherical surface 31a, and the step bar link 30 is a rotary ball ( 21) Rotate in the axial direction.

In addition, the ball stud 20 is formed integrally with the rotary sphere 21, the body portion 12 is inserted into the hollow portion 12 of the step bar 10 is formed, and the rotary sphere 21 and The catching jaw 22 is integrally formed between the body parts.

The locking jaw 22 is preferably formed larger than the diameter of the hollow portion 12 of the step bar 10 so that the body portion 25 is inserted only a predetermined length when inserted.

In addition, the locking jaw 22 serves to support the ball stud 20 to be fixed to the end of the step bar 10 when the body portion 25 is inserted.
