Description

Arm bush mounting structure for suspension

The present invention relates to a bush structure of a suspension arm, and more particularly, to a bush structure of a suspension arm for optimally adjusting the bush hardness of the suspension arm to improve the adjustment performance of the vehicle.

In general, the multi-link suspension structure constitutes a suspension arm including a trailing arm, an upper arm, a lower arm, and an assist arm, and the suspension arm serves to connect the vehicle body and the axle.

Here, all forces from the ground and the tire are transmitted to the vehicle body through the suspension arms, of which noise is generated when the forces generated by the uneven ground and the residual vibrations of the tire are transmitted to the vehicle body through the suspension arms. It causes excessive residual vibration, which causes inconvenience to passengers.

To solve this problem, suspension arms use rubber with excellent insulation to connect the body to the axle, which is called a suspension arm bush.

The suspension arm bush includes a tube bushing, a saddle stitching bush and a liquid sealing bush.

However, the prior art suspension arm bush should have a low rubber hardness to insulate the residual vibration transmitted from the tire to improve NVH performance. However, if the hardness of the bush is lowered, the suspension arm bush delays the lateral force transmitted from the tire to the body when turning the vehicle. There was a problem that the performance of the control greatly dropped.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a bush structure of a suspension arm for optimally adjusting the bush hardness of the suspension arm to improve the adjustment performance of the vehicle.

As a means for achieving the above technical problem, the present invention is a suspension structure of the suspension arm is an inner pipe; An outer pipe provided in a form surrounding the inner pipe; And a buffer member provided between the inner pipe and the outer pipe, the buffer member made of a synthetic resin, wherein the buffer member is formed in a form surrounding the inner pipe and is made of a synthetic resin of low hardness, and the inner buffer part and the outer part. It is provided between the pipe and characterized in that it is provided with an outer buffer portion made of a synthetic resin of high hardness.

According to the present invention, there is an effect of improving the adjustment performance of the vehicle by optimally adjusting the bush hardness of the suspension arm.

1 shows a bush structure of a suspension arm according to the invention.
Figure 2 is a perspective view of the inner buffer attached to the inner pipe according to the present invention.
3 is a cross-sectional view showing the bush structure of the suspension arm according to the present invention.

Suspension arm bush structure of the present invention having the above object and effect is an inner pipe; An outer pipe provided in a form surrounding the inner pipe; And a buffer member provided between the inner pipe and the outer pipe, the buffer member made of a synthetic resin, wherein the buffer member is formed in a form surrounding the inner pipe and is made of a synthetic resin of low hardness, and the inner buffer part and the outer part. It is provided between the pipes and provided with an outer buffer part made of a synthetic resin of high hardness.

Grooves and protrusions are formed in the concave-convex shape to be coupled to each other in the matching portion of the inner buffer portion and the outer buffer portion.

An embossing groove is formed in the outer circumferential surface of the inner buffer portion or the inner circumferential surface of the outer buffer portion.

The inner buffer or outer buffer is attached to the inner pipe or the outer pipe with an adhesive.

The outer shock absorbing portion is vulcanized between the inner shock absorbing portion and the outer pipe attached to the inner pipe, and then swaging.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

The bush structure of the suspension arm according to the present invention by applying different hardness of the inner and outer surfaces of the shock absorbing member 300 for absorbing and cushioning the impact force between the inner pipe 100 and the outer pipe 200, the insulation performance and the vehicle It is a configuration that can improve the coordination performance.

As shown in FIG. 1, the bush structure of the suspension arm according to the present invention has a cylindrical inner pipe 100 and a cylindrical outer pipe 200 provided in a form surrounding the outer circumferential surface of the inner pipe 100. And a cushioning member 300 provided between the inner pipe 100 and the outer pipe 200 and made of synthetic resin, and having inner and outer sides having different hardnesses.

Meanwhile, since the inner pipe 100 and the outer pipe 200 of the present invention are the same as the known art, detailed descriptions thereof will be omitted.

The shock absorbing member 300 of the present invention is provided in a form surrounding the inner pipe 100 and is provided between the inner shock absorbing portion 310 made of a synthetic resin of low hardness, and between the inner shock absorbing portion 310 and the outer pipe 200. And it is provided with an outer buffer 320 made of a synthetic resin of high hardness.

That is, the low hardness inner buffer portion 310 may improve the insulating property by minimizing the flow width by securing a large support force, and the high hardness outer buffer portion 320 by turning the vehicle by maximizing the flow width and Adjusting lanes can improve performance.

The inner buffer 310 is attached to the main surface of the inner pipe 100 through an adhesive 400. That is, an adhesive is first applied to the main surface of the inner pipe 100, and then the inner buffer 310 is attached along the main surface of the inner pipe 100.

In addition, the inner buffer 310 and the outer buffer 320 is attached through the adhesive (400).

Here, the matching portion of the inner buffer portion 310 and the outer buffer portion 320 is formed with grooves and protrusions, respectively, in a concave-convex shape for increasing mutual adhesion.

That is, the center of the outer circumferential surface of the inner buffer portion 310 to form a bulge projection 311 to protrude, and to form a recessed groove to be recessed in the inner center of the outer buffer portion 320 is supported by the bulge projection 311 Improved adhesion between the inner buffer 310 and the outer buffer 320.

In addition, an embossed portion 312 is formed on the outer circumferential surface of the inner buffer portion 310 so that the adhesive 400 is accommodated, and the adhesive 400 is uniformly formed on the entire inner buffer portion 310 by the embossed portion 312. It is possible to disperse and increase the adhesion, thereby improving the adhesion of the inner buffer 310 and the outer buffer 320.

On the other hand, the outer shock absorbing portion 310 is vulcanized between the inner shock absorbing portion 310 and the outer pipe 200 attached to the inner pipe 100 is made by swaging.

That is, the inner pipe 100 and the outer pipe 200 to which the inner shock absorbing part 310 is attached are disposed in a vulcanization molding apparatus, and the inner pipe 100 and the outer pipe 200 to which the inner shock absorbing part 310 is attached are disposed. Inject the synthetic resin added with sulfur to vulcanization by heating and pressurizing, and swaging after vulcanization to complete.

The scope of the present invention is shown by the following claims rather than the above description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
