孔１０４内での周方向の滑動をある程度防止している。FIG. 4 shows a state in which a stabilizer for suppressing rolling of the vehicle body is mounted on the vehicle body. As shown in this figure, the stabilizer bush 100 is formed such that the side surface thereof is substantially U-shaped. A through hole 104 for supporting the stabilizer 102, which is a rod-shaped member having a circular cross-section, in an inserted state is formed near the lower center of the stabilizer bush 100. The inner diameter of the through hole 104 (the inner diameter before the stabilizer 102 is inserted) is set to be slightly smaller than the outer diameter of the stabilizer 102, whereby the circumference of the stabilizer 102 in the through hole 104 is set. It prevents sliding in some direction.

の問題が生じる。That is, in a state before the stabilizer bush 100 is assembled to the body 106 by the bracket 110, the stabilizer bush 100 has a shape shown by a chain double-dashed line. The stabilizer bush 100 in this state is compressed to the body 106 side by the bracket 110, so that the stabilizer bush 100 becomes the state shown by the solid line. Therefore, the stabilizer bush 100
Is the distance P (= the center of the through hole 104 of the stabilizer bush 100 before assembly and the stabilizer bush 100 after assembly).
(Distance to the center of the through hole 104 of the bracket 11)
By 0, it means that it is compressed in the vertical direction. Therefore, in the assembled state, the through hole 104 of the stabilizer bush 100 does not have a perfect circular shape, but has an elliptical shape that is vertically compressed and has the longitudinal direction as its major axis. Therefore, the surface pressure acting on the outer peripheral surface of the stabilizer 102 via the inner peripheral surface of the through hole 104 of the stabilizer bush 100 becomes uneven. As a result, where the surface pressure becomes large (through hole 104
At the upper and lower ends, the noise caused by stick-slip and local wear occur and the surface pressure becomes small (through hole 104).
At the front and rear ends), a problem occurs such that a gap is created between both surfaces and foreign matter is mixed in.

ている。Further, an elliptical through hole 28 which is long in the vertical direction is formed near the lower center of the bush 24.
The bush 24 is cut from a predetermined peripheral portion of the through hole 28 to the top surface, and the through hole 28 is expanded by elastically deforming the cut surface 30 in a direction in which the through hole 28 is separated from each other. The stabilizer 32 (shown in outline by a chain double-dashed line) can be assembled. The stabilizer 32 is a torsion bar in which the axis of the pipe-shaped member is bent in a substantially U-shape, and is disposed in the through hole 28 in an inserted state so as to suppress the roll of the vehicle body.

The radial dimension d 2 of the through hole 28 in the minor axis direction is set smaller than the outer diameter dimension D of the stabilizer 32, and the radial dimension d 1 of the major axis direction is set larger than the outer diameter dimension of the stabilizer 32. . In addition, according to the formulas 2 and 3, the through hole 28 is retained even in the state of being pre-compressed by the bracket 18.

ブシュ２４の組付作業性は損なわれない。Next, the operation and effect of this embodiment will be described. In the state before the stabilizer 32 is inserted and arranged, the through hole 28 of the bush 24 has an elliptical shape that is long in the up-down direction and has a radial dimension in the major axis direction of d 1 and a radial dimension in the minor axis direction of d 2. Has been done. From this state, first, the bushing 24 is elastically deformed from the cut surface 30 to expand the through hole 28, and the stabilizer 32 is inserted into the through hole 28. Next, the bush 24 is attached to the middle portion of the bracket 18. At this time, since the distance between the bottom surfaces of the bush 24 facing the front and rear of the recess 26 is substantially equal to the distance between the inner surfaces of the bracket 18, the workability of assembling the bush 24 to the middle portion of the bracket 18 is impaired. I can't.

弾性的に支持される。After the bush 24 is attached to the intermediate portion of the bracket 18 as described above, the bolt insertion holes 20 on both sides of the bracket 18 and the bolt insertion hole 1 of the plate 12 are attached.
The bracket 18 is fixed to the body 10 by screwing the bolt 22 into the weld nut 16 via the connector 4. As a result, the stabilizer 32 is elastically supported by the body 10.

る。Since the distance L 2 <distance L 1 is set, the bush 24 is vertically compressed by (L 1 −L 2 ) by fixing the bracket 18 to the body 10. It will be. That is, the bush 24 is pre-compressed. The reason why the bush 24 is pre-compressed in this manner is to prevent the stabilizer 32 from sliding (relatively rotating) in the circumferential direction within the through hole 28. When the bush 24 is pre-compressed, the through hole 28, which has an elliptical shape that is long in the vertical direction, is compressed in the pre-compression direction (vertical direction) and becomes a substantially perfect circle. Therefore, the surface pressure acting from the inner peripheral surface of the deformed through hole 28 to the outer peripheral surface of the stabilizer 32 becomes substantially uniform.

From Equation 1 and Equation 2 described above, the outer diameter dimension D of the stabilizer 32
It becomes a little smaller than the above, and plays the role of preventing the stabilizer 32 from sliding (relative rotation) in the through hole 28 in combination with the precompression.

Since the shape of the through hole 28 provided in the bush 24 which is pre-compressed in the vertical direction by 8 and in which the stabilizer 32 is arranged in the inserted state is an elliptical shape that is long in the vertical direction, the state after pre-compression (after assembly) Thus, the surface pressure acting on the stabilizer 32 can be made substantially uniform, which can prevent the generation of abnormal noise due to stick-slip, the occurrence of local wear, and the inclusion of foreign matter.

とができる。With the bush 40, the same operation and effect as those of the above-described embodiment can be obtained. That is, when the bush 40 is attached to the middle portion of the bracket 18 and fixed to the body 10, the bush 40 is pre-compressed in the front-rear direction and the through hole 42 changes from an elliptical shape that is long in the front-rear direction to a substantially circular shape. . Therefore, the surface pressure acting on the stabilizer 32 becomes uniform, and it is possible to prevent the generation of abnormal noise due to stick-slip, the occurrence of local wear, and the inclusion of foreign matter. Also, in the present embodiment, the bush 4
With a simple configuration in which the shape of the 0 through hole 42 is changed,
Since the above effect can be obtained, cost reduction can be achieved.

Further, a track-shaped through hole 46 is formed which is composed of flat portions 46A and 46B which are parallel to each other and curved surface portions 46C and 46D having a predetermined radius of curvature which connect end portions of these flat portions 46A and 46B. When the bush 44 is pre-compressed in the vertical direction, the through hole 46 has a substantially perfect circular shape, so that the same effect as that of the above-described embodiment can be obtained.

In order to bring the shape of the bush into a shape of a perfect circle as close as possible, a track shape, an elliptical shape, etc. can be selected in consideration of the volume of the elastic bodies of the bushes 24, 40, 44, the elastic deformation amount, etc. , 42, 46 may be offset. That is, the shape and the position of the through hole may be determined in the direction away from the one that is easily deformed.

る。As described above, the bush structure according to the present invention as set forth in claim 1 is configured to make the surface pressure acting on the insertion member uniform or substantially uniform after precompression. A uniform or substantially uniform surface pressure can be applied to the insertion member inserted in the hole of the bush, and it is possible to prevent abnormal noise due to stick slip, localized uneven wear, and foreign matter from entering. It has an excellent effect that it can be done.

Since the radial dimension is set to be smaller than the radial dimension of the insertion member, a uniform or substantially uniform surface pressure can be applied to the insertion member inserted into the hole of the bush, which causes abnormal noise due to stick-slip. It has an excellent effect that it is possible to prevent the occurrence of local uneven wear and the occurrence of foreign matter.
