Description

Lateral link brackets on car bodies

The present invention relates to a lateral link bracket of an automobile body, and more particularly to a bracket structure for supporting a lateral link installed across the side frame of the vehicle body.

As shown in FIG. 1, the vehicle body undercarriage of the vehicle is installed on the floor panel covered at the bottom, left and right sides of the floor panel, and side frames 1 extending in the front and rear directions of the vehicle body, and both sides. It comprises a cross member (2) connected across the side frame of the.

Here, the left and right side frames 1 are provided with lateral links 3 for reducing the inclination of the vehicle body. The lateral link 3 is coupled by hinges to the first and second brackets 4, 5 fixed to one side frame 1. In addition, the third bracket 6 is mounted between the first bracket 4 and the cross member 2 in a structure in which the third bracket 6 is connected.

The first and second brackets 4 and 5 are simultaneously welded to the lower and side surfaces of the side frame 1, as shown in detail in FIGS. 2 and 3, and the flanges 4a and 5a are mutually connected. By welding.

According to such a configuration, the lateral link 3 mounted in the direction crossing the vehicle body prevents the vehicle body from inclining as a torsion bar when a difference occurs in rolling of the vehicle body or inclination of the left and right vehicle bodies.

In the above-described lower structure of the vehicle body, the bracket for supporting the lateral link, in particular, the first bracket is provided with a concave portion 4b and is formed in a stepped manner, which results in a complicated structure and poor moldability.

In addition, the second bracket to be welded to the first bracket has a problem in that the structure is complicated, the moldability is poor, and the number of welding points is large and the weldability is lowered.

Such a problem lowers the productivity and manufacturability of the product.

As proposed for the purpose of solving the problems of the prior art, the present invention simplifies the structure of the bracket on which the lateral link is supported, thereby improving the formability, weldability, and manufacturability.

In order to realize the above object, the present invention proposes a lateral link bracket of a vehicle body composed of the following means.

That is, the present invention includes a first bracket having a first welded portion attached to the side and bottom surfaces of the side frame, and an extension portion inclined downwardly from the first welded portion to which the lateral link is coupled by a hinge; A second bracket including a second welding part welded to a side of the side frame, and a third welding part welded to a flange surface of the extension part of the first bracket; It consists of a technical configuration including a third bracket coupled to the lateral link and the first bracket by a hinge and the opposite side is attached to the cross member.

The welded portion of the first bracket has the same width as the lower surface of the side frame, and the cross section of the extended portion is formed in a trapezoid.

In addition, an enlarged portion is formed in the second welded portion of the second bracket welded to the side frame, and a reinforcement bead is formed in the third welded portion of the second bracket welded to the first bracket.

Hereinafter, preferred embodiments for realizing the present invention will be described in more detail with reference to the accompanying drawings.

EXAMPLE

Figure 4 is a perspective view showing a lateral link mechanism of the vehicle body according to the present embodiment, Figure 5 is an exploded perspective view of Figure 3, Figure 6 is a cross-sectional view showing a connection structure of the lateral link and the bracket according to the present embodiment.

In describing the present embodiment, the same reference numerals are used for the configuration of the present embodiment, which is the same as the drawings cited in the prior art, and will not be described again for clarity.

In the drawings, reference numeral 1 denotes a side frame, and 2 denotes a cross member.

The cross member 2 which traverses a vehicle body is connected between the side frames 1 located long in the front and rear directions of the vehicle body. In addition, the left and right side frames 1 are provided with lateral links 3 for reducing the inclination of the vehicle body.

As a means for installing the lateral link 3, the lateral link bracket of this embodiment has a first weld portion 7a attached to the side and bottom of one side frame 1 at the same time, and downward from the first weld portion 7a. It comprises a first bracket (7) consisting of an extension (7b) is extended inclined to the lateral link 3 is coupled by a hinge.

Here, the first bracket 7 is formed to have the same width as that of the side frame 1 in order to increase the joining rigidity with the side frame 1 unlike the prior art. In addition, the height of the welded portion 7a is reduced, and the conventional recessed portion is removed to simplify the structure.

The third welding portion 8b of the second bracket 8 is joined by welding to the flange surface 7c of the extension portion 7b of the first bracket 7 thus constructed. Moreover, the 2nd welding part 8a extended directly from the upper end of the 3rd welding part 8b of the 2nd bracket 8 is welded to the side frame 1 of a vehicle body.

Here, an enlarged portion 8c is formed in the second welded portion 8a of the second bracket 8 to reinforce the strength of the welded portion 7a of the first bracket 7. In addition, a reinforcing bead 8d is formed in the third welding portion 8b of the second bracket 8.

The other end of the third bracket 6, one end of which is attached to the cross member 2, is extended in the extension portion 7b of the first bracket 7 welded to the second bracket 8 configured as described above. Together with the hinge 7d.

In the drawings, reference numeral 9 denotes a center floor panel of the vehicle body.

Based on the configuration of the present embodiment described above, the first bracket 7 of the lateral link has a conventional structure of the recess and the stepped structure, and has a simple structure of the first weld portion 7a and the extension portion 7b.

In addition, the extension portion 7b of the first bracket 7 is formed in a trapezoidal shape to improve rigidity.
