Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stabilizer mount for surely supporting a stabilizer bar by a stabilizer mount bush.

[0002]

2. Description of the Related Art As shown in FIG. 3, a suspension of an automobile has a lower arm 1 whose one end is rotatably attached to a vehicle body around a fulcrum P1 and a ball joint or the like at a fulcrum P2 at the other end of the lower arm 1. Is fixed to the lower arm 1 by a stabilizer link 7 via a knuckle arm 2 connected via a knuckle arm, a suspension strut 4 attached to the knuckle arm 2 and supporting a vehicle body via a spring 3, and joints 5 and 6 such as ball joints. It is composed of a stabilizer bar 8.

The stabilizer bar 8 is a single bar bent in a U-shape, and the lower arm 1 swings when the vehicle goes straight (only one side is shown in FIG. 3 and the other side is omitted). As a result, the stabilizer bar 8 is rotated, and the inclination of the vehicle body to the outside due to the centrifugal force when the vehicle turns is regulated by the torsional force corresponding to the arm length L (see FIG. 4) of the stabilizer bar 8 and The tilt is eliminated to ensure stable driving. Therefore, the stabilizer bar 8 allows rotation during straight traveling and twist during turning so that this function can be exerted, and the stabilizer bar 8 is fixed to the vehicle body side through the stabilizer mount bush 9 and attached to the vehicle body by the mounting bracket 10. It is fixedly supported.

As shown in FIG. 4 (only one side is shown and the other side is omitted), the conventional mount support of the stabilizer bar is machined according to the diameter of the stabilizer bar 8 as shown in FIG.
Type stabilizer mount bush 11 is fitted on the stabilizer bar 8, and this stabilizer mount bush is
A mounting bracket (hereinafter referred to as a C-shaped mounting bracket) 12 having an arc portion processed according to the outer shape of 11 and a receiving bracket 15 presses the outer peripheral surface of the stabilizer mount bush 11 so that the outer peripheral surface of the stabilizer mounting bush 11 is pressed and the C-shaped mounting is performed with a bolt 13. The metal fitting 12 is fastened to and supported by the screw hole 14 provided on the vehicle body side. Further, the support of a stabilizer bar using such a C-shaped mounting bracket is disclosed in Japanese Patent Laid-Open No. 612000/1986.

[0005]

However, there are the following problems in the mount support of the stabilizer bar using the above-mentioned conventional C-type mounting bracket. That is, as shown in FIG. 3, when the lower arm 1 rotates about the fulcrum P1 as shown by the broken line, the stabilizer link 7 tries to move by L, and the force of the stabilizer link 7 to move is the stabilizer bar 8 Acts as a force F that pushes in the direction of the arrow.

Therefore, the pushing force F and the turning force due to the twisting force of the stabilizer bar 8 simultaneously act on the stabilizer mount bush 9 (hereinafter simply referred to as synthetic force), and this synthetic force acts on the stabilizer mount bush 9 while the vehicle is traveling. Will work repeatedly. Therefore, as shown in FIG. 4, when this combined force acts on the stabilizer mount bush 11 fastened with the C-type mounting bracket 12, a deviation occurs between the stabilizer mount bush 11 and the C-type mounting bracket 12, and the stabilizer mount There is a problem that excessive force is applied in a deformed state of the bush 11 and the life of the stabilizer mount bush 11 is shortened. Therefore, there is a problem that the frequency of replacing the stabilizer mount bush 11 increases.

Further, the stabilizer mount bush 11
If the replacement is frequently performed, the screw thread of the screw hole 14 provided on the vehicle body side is likely to be damaged, and if the screw thread of the screw hole 14 is damaged, it will be necessary to repair it. There is a problem that replacement work becomes difficult.

The present invention solves the above problem by preventing the stabilizer mount bush from being forced.
It is intended to provide a stabilizer mount designed to reliably support the mount of a stabilizer bar.

[0009]

Means for Solving the Problems According to the present invention for solving the above problems, a C type stabilizer mount bush is fitted to a stabilizer bar, and a through hole is formed in the C type end of the stabilizer mount bush. A bracket having a U-shape having flanges formed on both sides is fixed to the vehicle body side on one side, and a through hole corresponding to a through hole formed at the C-shaped end of the stabilizer mount bush is opened in the flange of the bracket. The bracket flanges are positioned on both sides of the stabilizer mount bush, and bolts are inserted through the through holes formed in the C-shaped end of the stabilizer mount bush and the through holes formed in the bracket flange to insert the bracket and the stabilizer mount bush. It is characterized by combining.

[0010]

The present invention having the above-mentioned structure has the following functions. That is, a C-shaped stabilizer mount bush is fitted to the stabilizer bar, and a U-shaped bracket having flanges formed on both sides is fixed to the vehicle body side, and the flanges are positioned on both sides of the stabilizer mount bush. , Since the bolt is inserted through the through hole formed in the C-shaped end of the stabilizer mount bush and the through hole formed in the flange of the bracket to connect the bracket and the stabilizer mount bush, the deformation of the stabilizer mount bush depends on the inserted bolt. By allowing the stabilizer mount bush to move by being guided by the bolts that are constrained and inserted along with the movement of the stabilizer bar, it is possible to eliminate an unreasonable force acting on the stabilizer mount bush. As a result, of the combined forces, the force received by the stabilizer mount bush is only the force in the turning direction and the twisting direction of the stabilizer bar, and this force is absorbed by the flexibility of the stabilizer mount bush.

[0011]

EXAMPLE An example of the present invention will be described below. In FIG. 1, the stabilizer mount bush 16 is a C-shape molded according to the outer shape of the stabilizer bar 8, and a through hole 17 is formed at the end of the C-shape.
Further, the stabilizer mount bush 16 is provided with a band 18 for strengthening the crimping force when the stabilizer bar 8 is fitted to the stabilizer mount bush 16 as shown by the broken line. Reference numeral 19 is a collar inserted into the through hole 17.

The bracket 20 has a U shape in which both ends of the back plate 24 are bent at a substantially right angle to form a flange 21.
This flange 21 has stabilizer mount bush 16
A hole 22 corresponding to the through hole 17 formed in the C-shaped end is formed, and a seat having a screw hole 23 on the outside is fixed to one hole 22. Further, a bolt hole 25 is formed in the back plate 24, and the bracket 20 is fastened to a screw hole 26 provided on the vehicle body side by passing a bolt 28 through the bolt hole 25.

The flange 21 is provided with a recess 29 in conformity with the outer shape of the stabilizer bar 8. Bracket 20 Flange 21 Comrade width W2 is stabilizer mount bush
It is wider than the width W1 of 16 so that a gap C is formed between the inside of the flange 21 and the side surface of the stabilizer mount bush 16 as shown in FIG. The gap C is determined in consideration of the movement amount of the stabilizer bar 8. For example, it is possible to allow the movement of the stabilizer bar 8 to some extent and to restrain the movement beyond that.

Numeral 27 is a bolt, and after the stabilizer mount bush 16 is fitted on the stabilizer bar 8, the stabilizer mount bush 16 is positioned between the flanges 21 of the bracket 20 already attached to the body of the vehicle body, and the through hole 17 is formed. The inserted collar 19 and the through hole 22 of the flange 21 are aligned and the bolt 27 is inserted and screwed into the screw hole 23. As a result, the stabilizer mount bush 16 and the bracket 20 are connected. The collar 19 is made of metal or hard plastic, for example.

The operation of this embodiment having the above-described structure will be described below. First, the assembly will be described. The bracket 20 is fastened to the screw hole 26 by the bolt 28 and fixed to the vehicle body side, while the stabilizer mount bush 16 is fitted to the stabilizer bar 8. In this fitting, the stabilizer mount bush 16 may be fixed to the stabilizer bar 8 with an adhesive or the like. Next, the stabilizer mount bush 16 is positioned between the flanges 21 of the bracket 20, and the through hole 22 of the bracket 21 and the collar 19 inserted into the through hole 17 formed at the C-shaped end of the stabilizer mount bush 16 are inserted. After aligning the position, the bolt 27 is inserted and screwed into the screw hole 23. In this case, by making the distance between the through holes 22 a little smaller than the distance between the through holes 17, the force of fitting the stabilizer mount bush 16 to the stabilizer bar 8 can be increased.

When a force F as shown in FIG. 3 is exerted on the stabilizer bar 8 thus mounted and supported, the stabilizer mount bush 16 can be moved by being guided by the bolt 27. It moves together with the stabilizer bar 8 and an unreasonable force does not act on the stabilizer mount bush 16 against the force F, so that the stabilizer mount bush 16 can be prevented from being deformed.

Also, the stabilizer mount bush 16
Since the deformation is restricted by the bolts 27 supported at both ends by the flange 21 of the bracket 20, the deformation of the stabilizer mount bush 16 can be prevented more reliably. In addition, the use of the collar 19 improves the sliding force between the bolt 27 and the bolt 27 in the direction of the force F.
The movement of 16 is facilitated, and the C-shaped end portion of the stabilizer mount bush 16 is reinforced by the collar 19, so that the deformation of the stabilizer mount bush 16 can be prevented more effectively.

By setting the gap C shown in FIG. 2, the movement of the stabilizer bar 8 in the force F direction can be restrained by the flange 21 of the bracket 20. That is, since the stabilizer mount bush 16 is not deformed as described above, the state where the stabilizer mount bush 16 is pressed against the flange 21 is the pressure contact between the surfaces. Therefore, this pressure contact force is dispersed on the side surface of the stabilizer mount bush 16 and does not damage the stabilizer mount bush 16.

Next, twisting and rotation of the stabilizer bar 8 are allowed by the flexibility of the stabilizer mount bush 16. That is, the stabilizer mount bush 16 is completely restrained by the bolts 27 supported at both ends of the flange 21 of the bracket 20 against the movement and twisting deformation of the stabilizer bar 8, and the stabilizer mount bush 16 is also restrained. Since 16 is fixed to the stabilizer bar 8, the stabilizer mount bush 16 can be deformed only in the twisting and rotating direction of the stabilizer bar 8 when the stabilizer bar 8 is twisted or rotated.

In this way, the stabilizer mount bush 16 can be deformed only in the twisting and rotating directions of the stabilizer bar 8, so that there is no hindrance to the movement in the force F direction shown in FIG. 3 and twisting of the stabilizer bar 8. Since the stabilizer mount bush 16 can move in the force F direction, the combined force acting on the stabilizer mount bush 16 by the rotation and the movement in the force F direction is only the twisting force and the force in the rotating direction of the stabilizer bar 8. There is no deformation such that the stabilizer mount bush 16 is twisted so as to come off the stabilizer bar 8, and the mount support of the stabilizer bar 8 can be ensured.

Next, the stabilizer mount bush 16
Since the bolt can be replaced by removing the bolt 27, it is not necessary to remove the bracket 20 and the screw hole 26 provided on the main body side is not damaged.

[0022]

As described in detail above, according to the present invention, a C type stabilizer mount bush is fitted to a stabilizer bar, and a through hole is provided at the C type end of the stabilizer mount bush, and one side has flanges on both sides. C-shaped bracket that has been formed on the side of the vehicle body is fixed, the flanges are located on both sides of the stabilizer mount bush, and the through hole made in the C-shaped end of the stabilizer mount bush and the penetration made in the flange of the bracket Since the bolt is inserted into the hole and the bracket and stabilizer mount bush are connected, the deformation of the stabilizer mount bush can be restrained by the inserted bolt, and the stabilizer bar is guided by the inserted bolt as the stabilizer bar moves. The mount bush can also move May be so it is possible to eliminate the excessive force acting on the stabilizer mounting bushes, the stabilizer mounting bush of the resultant force receives only rotation and torsion force of the stabilizer bar.

As described above, since the deformation of the stabilizer mount bush is restrained by the bolt and the excessive force is not applied, the deformation of the stabilizer mount bush can be surely prevented, and the useful life of the stabilizer mount bush is improved. Can be greatly extended, and the frequency of replacement of the stabilizer mount bush can be greatly reduced. Further, since it is not necessary to remove the bracket when replacing the stabilizer mount bush, the screw hole provided on the vehicle body side is not damaged.

In addition to the fact that the stabilizer mount bush is securely prevented from being deformed, the stabilizer mount bush is designed to receive only the force in the rotation and twisting direction of the stabilizer bar. The stabilizer bar can be reliably supported without exerting a force that causes the stabilizer bar to come off.
