Description

Shock absorber {Insulator for shock absorber}

The present invention relates to an insulator of a shock absorber, and more particularly, an upper plate and a lower plate having obliquely formed holes in both directions, and a connecting member connected to both ends of the hole to rotate between the upper plate and the lower plate. The insulator of the installed shock absorber.

1 is a front view showing a shock absorber of a typical vehicle.

In general, the shock absorber of the vehicle, as shown in Figure 1, the strut (2) integrally installed with the steering knuckle (1), the suspension arm (3) and the spring (4) is installed below the strut (2) And the like.

Both ends of the suspension arm 3 are connected to the struts 2 and the lower members by ball joints 3a and 3b, and the struts 2 are spring upper seats on which both ends of the springs 4 are seated. 5 and the spring lower seat 6 are provided.

The spring (4) is installed so as to resist the lateral force (F) by giving a constant offset (θ) with respect to the strut (2) its central axis.

The lower part of the strut 2 has a cylinder structure, and the upper part of the strut 2 has a rod structure inserted into the cylinder.

An upper end of the strut 2 having a rod structure is coupled to the vehicle body through an insulator 7, and a thrust bearing (not shown) is installed inside the insulator 7, and the weight of the vehicle is the insulator 7. The vehicle body is supported through the steering, and when the steering is performed, the strut 2 is rotated together with the steering knuckle 1.

In the shock absorber configured as described above, when vertical vibration occurs in the wheel 8 while driving the vehicle, the vibration is transmitted to the spring 4 through the steering knuckle 1 and the strut 2 so that the spring 4 is free vibration. Done. At this time, since the spring 4 is installed obliquely with respect to the vehicle body, due to the difference between the force action direction of the spring 4 and the force direction in which the vehicle load acts on the strut 2, the strut 2 is The force acting in the transverse direction on the rod of the strut 2, that is, the lateral force (F). The free vibration of the spring (4) is a spring upper seat (5) installed on the upper portion of the strut (2) having a rod structure, and a spring row installed at the lower portion of the strut (2) having a cylindrical structure into which the rod is inserted. Between the seats 6, the free vibration of the spring 4 is absorbed and the riding comfort can be secured while the rod is inserted into and withdrawn from the cylinder.

FIG. 2 is a view illustrating an insulator of a shock absorber according to the prior art and its main parts thereof, and FIG. 3 is a schematic front view of a vehicle for explaining a rolling phenomenon in a right turn of a vehicle in which the insulator of the shock absorber according to the prior art is installed. .

The insulator of the shock absorber according to the related art is composed of an upper plate 100 and a lower plate 200, as shown in FIG. 2, and an outer insulator outside the upper plate 100 and the lower plate 200. The rubber member 300 is formed to form an appearance of the. On the other hand, the upper plate 100 and the lower plate 200 is formed with a hole 110 is inserted into the upper end of the strut (2) described in FIG.

However, a vehicle equipped with a shock absorber insulator according to the prior art has a problem in that a rolling phenomenon occurs when the vehicle is turned and the ground area between the tire and the road surface is reduced, such that the tire is pushed and the vehicle is rotated during the sudden turning of the vehicle.

The rolling phenomenon will be described with reference to FIG. 3 by taking a right turn of the vehicle as an example. When the vehicle 400 turns right, the right tire 500 becomes a + camber, and the left tire 600 becomes a-camber. At this time, the tires 500 and 600 are considerably inferior in the lateral direction with respect to the road surface 700, such as a portion divided by a circular dotted line.

SUMMARY OF THE INVENTION An object of the present invention is to provide an insulator for a shock absorber in which rolling phenomenon is eliminated during vehicle turning and the ground area between the tire and the road surface is increased.

The present invention includes an upper plate having a first hole drilled at an angle in both directions; A lower plate having a second hole drilled in the same direction as the first hole; Both ends are connected to the first hole and the second hole to provide an insulator of a shock absorber including a connection member installed to be rotatable between the upper plate and the lower plate.

The connecting member provides an insulator of a shock absorber formed of a hollow hollow tube.

The insulator of the shock absorber according to the present invention comprises: an upper plate having a first hole drilled obliquely in both directions; A lower plate having a second hole drilled in the same direction as the first hole; Both ends are connected to the first hole and the second hole, and include a connecting member installed between the upper plate and the lower plate so as to be rotatable, so that rolling phenomenon is eliminated when the vehicle is turned and the ground area between the tire and the road surface is eliminated. This has an increasing effect.

An embodiment of the present invention having the above-described effect will be described in detail with reference to the accompanying drawings.

Figure 4 is a view showing the insulator and its main portion of the shock absorber according to the present invention, Figure 5 is a plan view and a bottom view of the main portion of the insulator of the shock absorber shown in Figure 4, Figure 6 is a shock absorber shown in Figure 4 Figure 7 is a view showing the operating state of the main portion of the insulator, Figure 7 is a schematic front view of the vehicle for explaining that the rolling phenomenon is removed when the right turn of the vehicle is installed the insulator of the shock absorber according to the present invention.

As shown in FIG. 4, the present invention includes an upper plate 10 having the first hole 15 obliquely formed in both directions; A lower plate 20 having the second hole 25 drilled in the same direction as the first hole 15; Both ends are connected to the first hole 15 and the second hole 25 to include a connecting member 30 installed between the upper plate 10 and the lower plate 20 to be rotatable.

The upper plate 10 is formed in a substantially bowl shape bent upward in the circumferential direction, the lower plate 20 is formed in a substantially bowl shape bent downward in the circumferential direction.

The outer side of the upper plate 10 and the lower plate 20 is coated with a rubber member 40 to form the appearance of the insulator.

The connecting member 30 is formed as a hollow hollow tube to connect the first hole 15 and the second hole 25, and the upper end of the strut 2 shown in FIG. 1 is inserted.

As shown in FIG. 5, the first hole 15 and the second hole 25 are perforated obliquely in both directions, so that the connecting member 30 is rotated as shown in FIG. By tilting at an angle, the tires 500 and 600 are guided in the direction 500 'and 600' shown by the dotted lines in FIG. 7 to eliminate the rolling phenomenon described in FIG. 3 of the prior art, and as a result, the tires 500 and 600 are shown in FIG. Positioning as shown by the solid line 7 increases the ground area between the tires 500, 600 and the road surface 700, thereby preventing the tire from rolling and the dangerous situation in which the vehicle is rotated during the sudden turning of the vehicle 400. .

In addition, when the vehicle is turned to the left, the connecting member 30 is inclined at an angle as shown in FIG. In FIG. 7, the same reference numerals are used for comparison with FIG. 3 of the related art.

When the insulator of the shock absorber according to the present invention is used, the rolling phenomenon is eliminated when the vehicle is turning and the ground area between the tire and the road surface is increased, thereby preventing a dangerous situation in which the tire is pushed and the vehicle is rotated during the sudden turning.
