Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension arm. More specifically, the arm reinforcing plate is provided with a bent portion, and the bent portion is brought into contact with the bottom portion of the suspension arm body to increase the height of the arm reinforcing plate. A suspension in which the arm reinforcing plate is attached to the suspension arm body after positioning in the direction.

[0002]

2. Description of the Related Art Conventionally, there are suspension arms in which an arm reinforcing plate is positioned and attached to a suspension arm body by various methods. When attached to the suspension arm body, the arm reinforcing plate forms a closed cross section with the suspension arm body, and increases the strength of the suspension arm. 6 and 7
Shows an example of such a suspension arm. In this example, a bent portion 3 is provided on the arm reinforcing plate 2 of the suspension arm 1, and the bent portion 3 is brought into contact with the bottom portion 4a of the suspension arm body 4 to position the arm reinforcing plate 2 in the height direction. The arm reinforcing plate is attached to the suspension arm body 4. In this suspension arm 1, the positioning of the arm reinforcing plate 2 in the horizontal direction is performed using the position gear pin 5 as shown in FIG.

[0003]

In the suspension arm 1 as described above, the positioning pin 5 is used to position the arm reinforcing plate 2 in the horizontal direction, so that the arm reinforcing plate is assembled. There was a problem that the work became complicated and took time. In particular, when the arm reinforcing plate 2 is attached to the curved portion of the suspension arm body 4, it is difficult to accurately position the arm reinforcing plate 2. The present invention
It was made in view of the above situation, with a simple configuration,
An object of the present invention is to provide a suspension arm capable of easily and quickly and accurately positioning and mounting the arm reinforcing plate.

[0004]

According to the present invention, in order to achieve the above object, a bent portion is provided on an arm reinforcing plate, and the bent portion is brought into contact with a bottom portion of a suspension arm body to provide the arm reinforcing plate. In the suspension in which the arm reinforcing plate is attached to the suspension arm main body after positioning in the height direction of the vehicle, the first portion having a notch having a shape corresponding to the shape of the ball joint is bent at a substantially right angle. The thus formed stabilizer joint seat flange and the second portion extending to the boss are integrally formed on the arm reinforcing plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a suspension arm according to the present invention will be described in detail below with reference to the accompanying drawings. 1 to 5 show an embodiment of a suspension arm according to the present invention. In the suspension arm 10 of this embodiment, the arm reinforcing plate 11 includes a first portion 12, a stabilizer joint seat portion flange (folded portion) 13,
The second portion 14 and the second portion 14 are integrally formed. Here, the first portion 12 is formed at one end of the arm reinforcing plate 11 in a shape including a substantially U-shaped notch 16 corresponding to the shape of the ball joint portion 15. The stabilizer joint seat portion flange 13 is formed by being curved in a shape corresponding to the shape of the stabilizer joint portion 17, and being bent downward at a substantially right angle. Second part 14
Is formed by extending the other end of the arm reinforcing plate 11 to the boss portion 18. Further, the arm reinforcing plate 11 has a side wall 19 having one end constituting the stabilizer joint seat portion flange 13 and curved corresponding to the curved shape of the suspension arm body 20, and a flat plate shape of the suspension arm body 20. The side wall 21 formed is further provided. The suspension arm main body 20 is formed in a substantially U-shaped cross section by the side walls 22, 23, 24 and the like so as to open upward, and has a ball joint portion 15 at one end and a boss portion 18 at the other end. And a stabilizer joint seat portion 25 to which the stabilizer joint portion 17 is fixed is provided substantially at the center thereof. The side wall 22 of the suspension arm body 20 is curved corresponding to the side wall 19 of the arm reinforcing plate 11, and the side wall 23 is formed in a substantially flat plate shape corresponding to the side wall 21 of the arm reinforcing plate 11. In FIG. 1, 26 is a suspension, 27 is a stabilizer bar, and 28 is a wheel.

In this embodiment, the arm reinforcing plate 11 is attached to the suspension arm body 20 as follows. That is, in the suspension arm 10 of the present embodiment, the first portion 12 of the arm reinforcing plate 11 is aligned with the ball joint portion 15, and then the side walls 19, 21 of the arm reinforcing plate 11 are aligned with the side walls 22, 23, while the second portion 14 of the arm reinforcing plate 11 is aligned. Boss part 1
Put on 8. As a result, in the arm reinforcing plate 11, the stabilizer joint seat flange 13 is abutted against the bottom portion 20a of the suspension arm body 20, and the second portion thereof is placed on the boss portion 18,
The positioning in the height direction is performed. Further, the side walls 19 and 21 of the arm reinforcing plate 11 are aligned with the side walls 22 and 23 of the suspension arm body 20, whereby the arm reinforcing plate 11 is positioned in the horizontal direction. As described above, in the present embodiment, the arm reinforcing plate 11 can be accurately and easily positioned and attached without using the conventional positioning pin. Further, in this embodiment, since the reinforcing plate of the ball joint portion 15 which is a separate part in the related art is integrally formed with the arm reinforcing plate 11 as the first portion 12, the number of parts is reduced and the efficiency of the assembling work is improved. It is possible to plan.

[0007]

As described above, according to the suspension arm of the present invention, the arm reinforcing plate is provided with the bent portion, and the bent portion is brought into contact with the bottom portion of the suspension arm main body. In the suspension in which the arm reinforcing plate is attached to the suspension arm body after positioning in the height direction of the first part, a first part having a notch having a shape corresponding to the shape of the ball joint part;
Since the stabilizer joint seat flange formed by bending at a substantially right angle and the second portion extending to the boss are integrally formed on the arm reinforcing plate,
The following effects can be obtained. That is, in the present invention, the first portion of the arm reinforcing plate is aligned with the ball joint portion of the suspension arm body, and then,
The stabilizer joint seat flange is abutted against the bottom of the suspension arm body, and the second portion is placed on the boss portion of the suspension arm body to position the arm reinforcing plate in the horizontal and height directions. can do. Therefore, the arm reinforcing plate can be easily and promptly and accurately positioned and attached without using a positioning pin as in the prior art.
