DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Even if the terms are the same, it is to be noted that when the portions to be displayed differ, the reference signs do not coincide.

The terms to be described below are terms set in consideration of functions in the present invention, and may be changed according to a user's intention or custom such as an experimenter and a measurer, and the definitions should be made based on the contents throughout the present specification.

3 is a perspective view of a tie rod coupling structure according to the present invention. A feature of the present invention is that one clamp is used to join the tie rod 10 and the ball joint assembly. That is, one side of the tie rod 10 is provided with an adjustable portion 20 that can adjust the length of engagement with the ball joint assembly, the other side is provided with a fixed portion 30 is completely fixed to the ball joint assembly.

In the conventional tie rod coupling structure shown in FIG. 2, since the tie rod is rotated to adjust the length, it has been described that both sides of the tie rod should be adjusted. The present invention, on the other hand, proposes a new type of coupling structure capable of adjusting the length without rotating the tie rod 10.

In addition, one of the important objects of the invention requires a form in which the tie rods are bent as shown in FIG. 3 to prevent interference with the structure of the underside of the vehicle as described in the background art. However, in the way of adjusting the length by rotating the tie rod as in the present, it is not possible to apply such a curved tie rod. Accordingly, the present invention provides a new structure that enables the length adjustment without rotating the tie rod itself.

As an embodiment for implementing this, Figure 4 is an exploded perspective view of the adjustment portion of the tie rod coupling structure according to the present invention, Figure 5 shows a cross-sectional view of the adjustment portion of the tie rod coupling structure according to the present invention.

The tie rod 10 used in the present invention has a first fastening hole 12 and a second fastening hole 14 formed in both ends in the axial direction. Herein, the term “formed in the axial direction” means that the tie rod 10 is formed in the longitudinal direction as shown in FIG. 4. The first fastening hole 12 forms the adjusting part 20, and the second fastening hole 14 forms the fixing part 30.

As used herein, the term "fastening hole" means any shape to which a protruding member can be inserted, and is not limited to a hole shape.

The first fastening hole 12 and the second fastening hole 14 are preferably provided to have a circular cross section. This is because the member inserted into the first fastening hole 12 and the second fastening hole 14 is inserted through rotation.

The through-hole adjustment pipe 24 is inserted into the first fastening hole 12. The adjustment pipe 24 is provided to enable adjustment of the length inserted with respect to the first fastening hole 12. To this end, a first thread is formed on the inner surface of the first fastening hole 12, and a thread corresponding to the first thread is formed on the outer surface of the control pipe 24. When the control pipe 24 rotates, the control pipe 24 is inserted into or discharged from the inside of the first fastening hole 12 according to the thread of engagement.

The first ball joint assembly 21 is provided with a first engagement portion 22 that is inserted into the adjustment pipe 24, as shown in FIG. 4. A second thread is formed on the outer surface of the first coupling portion 22, and a thread corresponding to the second thread is formed on the inner surface of the control pipe 24. Rotating the control pipe 24 is a structure in which the length of the control pipe 24 and the first coupling portion 22 changes according to the thread of engagement.

As shown in FIG. 4, the adjusting pipe includes a catch portion having a polygonal cross section such as a hexagon, which can be fixed through a spatter, and a thread portion formed with a thread to adjust the length.

However, in order to increase the tightening force of the clamp 27, it is preferable to form three to four cutouts 29 in the adjustment pipe 24. When generating the tightening force using the clamp 27, the adjusting pipe 24 is subjected to the tightening force through the end 11 of the tie rod 10, the spacing of the incision 29 of the adjusting pipe 24 As this decreases, the control pipe 24 fixes the first coupling portion 22 more strongly. The cutout 29 is preferably formed in the threaded portion.

The core of the present invention, unlike the conventional tie rod coupling structure in FIG. 2, aims to adjust the length formed by the tie rod and the ball joint assembly by rotating the adjustment pipe 24 without rotating the tie rod. . As a result, since only one side of the tie rod is fixed and loosened to adjust the length, there is an advantage in that workability and convenience are improved as compared with the conventional technology of performing both fixed and loosened processes. This is shown in detail in FIG. 5.

After adjusting to the desired length, it is necessary to fix the adjusting pipe 24 so that the adjusting pipe 24 does not rotate relative to the first fastening hole 12 (the length is not changed). To this end, it is preferable to increase the friction between the control pipe 24 and the first fastening hole 12 by using the clamp 27. The clamp 27 is provided with a clamp fastening member 28 to increase the force of the first fastening hole 12 to bite the control pipe 24.

However, in order to increase the force that the end 11 of the tie rod 10 clamps the control pipe 24, it is preferable to form the cutout 19 at the end 11 of the tie rod 10 as shown in FIG. 4. Do. When the clamping force is generated by using the clamp 27, the end of the tie rod 10 fixes the control pipe 24 more strongly while the gap between the incisions 29 is reduced.

In order to further enhance this effect, the length of the cutout 19 is preferably formed longer than the length of the control pipe 24.

It is preferable that one or more such cutouts 19 are provided, and two to four are preferably provided at equal intervals in the circumferential direction, but the number thereof does not limit the scope of the present invention.

Hereinafter, the fixing part 30 of the tie rod 10 will be described. The second coupling part 32 of the second ball joint assembly 31 is inserted into and fixed to the second fastening hole 14. However, unlike the adjuster 20, the second coupling part 32 should be completely fixed to the second fastening hole 14.

Therefore, it is preferable to join the second fastening hole 14 and the second coupling part 32 through a hot crimping process. As shown in FIG. 6, a hot crimping process is a process of joining while increasing a resistance to detachment by placing a corrugation shape in a coupling portion between the second fastening hole 14 and the second coupling portion 32. to be. Since the tie rod 10 is joined to have a very high friction force, the tie rod 10 becomes impossible to rotate with respect to the second ball joint assembly 31.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. .
