Description

A Link Structure for Carrier Integrated Trailing Arm

The present invention relates to a carrier integrated trailing arm having a structure for maintaining a fastening strength when fastening a link to a ball joint.

It is an efficient structure for mass production by reducing the weight and material cost by changing the carrier made of castings into a press part and dividing the trailing arm and the carrier with a press in dual suspension.

Meanwhile, such a carrier integrated trailing arm should be equipped with links such as a lower arm, an upper arm, and an assist arm mounted on the carrier.

As shown in FIG. 1, the assist arm mounting bracket 13, the upper arm mounting bracket 14, and the lower arm mounting bracket 15 have a structure in which the trailing arm 11 and the carrier 12 are integrally formed. Each of them was formed, for example, a structure in which a bush mounting 22 provided at an end of the assist arm 21 is sandwiched between the brackets 13 and fastened with a bolt.

However, this structure has a problem in that the handling performance is worse than the ball joint.

2, when the ball joint is applied, the ball joint 24 of the assist arm 23 must be fastened to the assist arm mounting bracket 18 formed on the carrier 17 integrated trailing arm 16. As shown in 3 cantilever structure is very durable.

Therefore, in order to reinforce this, sufficient reinforcement should be made between the main panel and the assist arm mounting bracket, which causes a problem that the weight and material cost saving effect is reduced because a lot of weight is added.

The present invention has been made to solve the above problems of the prior art, it is an object to provide a simple link fastening structure while applying the same conventional ball joint.

The present invention to solve the above problems,

In the carrier-integrated trailing arm in which the trailing arm 31 and the carrier 32 are integrally formed,

Through hole 35 formed on the side of the carrier 32,

A plate 33 to which the caliper and bearing are mounted and fastened to the carrier 32,

It is bent on the side of the plate provides a link fastening structure of a carrier integrated trailing arm including an assist arm mounting portion 34 exposed through the through hole 35.

It includes a reinforcing plate (36,37) formed on the carrier integrated trailing arm and disposed on the side of the through hole.

The reinforcing plates 36 and 37 are formed on a carrier integrated trailing arm to support both sides of the assist arm mounting portion 34.

According to the present invention described above, in the multi-link structure by fastening the suspension arm with the ball joint has the advantage of maintaining the rigidity while reducing the weight and material of the carrier integrated trailing arm while improving the vehicle handling performance.

1 and 2 are views showing a link fastening structure of a conventional carrier integrated trailing arm,
3 is a cross-sectional view of the link fastening structure of FIG.
4 is a view showing a forming position of the assist arm mounting portion of the present invention;
5 is a view showing a state in which the assist arm mounting portion of FIG. 4 is fastened to a carrier integrated trailing arm, and
6 is a view showing a fastening structure of the reinforcing plate provided on the carrier integrated trailing arm of FIG.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

According to the present invention, the assist arm mounting portion 34 is bent on the plate 33 to which the caliper and the bearing are mounted and fastened to the carrier 32, and the inner side is formed through the through hole 35 formed on the side of the carrier 32. It is a subject matter of the present invention to allow the assist arm to which the ball joint is applied while being supported by the plate 33, which is a relatively rigid member, by being exposed and engaging the ball joint to the exposed portion.

That is, the present invention forms a through hole 35 which communicates the inside and the outside of the carrier-integrated trailing arm as shown in FIGS. After bending the side and forming the assist arm mounting portion 34 at the end thereof, when the plate is fastened to the carrier, the assist arm mounting portion 34 is exposed inwardly through the through hole 35 and the ball is It is to fasten the assist arm to which the joint is applied.

According to such a structure, since the ball joint is fastened to the plate joint by utilizing the fastening force of the plate fastened in the past, and utilizing the high rigidity of the plate itself, it is possible to prevent the structure from becoming complicated and add weight due to additional reinforcement. .

In addition, reinforcing plates 36 and 37 may be additionally formed on the carrier integrated trailing arm to accurately position and additionally reinforce the assist arm mounting part 34 during assembly.

It is formed on both sides of the through hole 35, it is preferable to support both sides of the assist arm mounting portion 34.
