Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support portion structure on a fixed end side of a suspension such as a leaf spring or a stabilizer used in an automobile or the like.

[0002]

[Prior Art]

 Conventionally, as this kind of suspension, there is a cab stabilizer as shown in FIG. That is, in the figure, A is a shaft rotatably fixed to the chassis side, the base ends of the arms B are fixed to both ends of the shaft A, and the other ends of both arms B are connected via a supporting portion C. It is fixed to the cab. Then, at the time of rolling in which the cab inclines in the left-right direction, a step is generated in the left and right arms B, which causes a return reaction force to control the rolling. However, at the time of the rolling, an unreasonable force (prying force) is exerted on the supporting portion C itself, which may cause inconvenience such that the supporting portion C is worn or damaged.

In order to solve such an inconvenience, as shown in FIG. 7, a spherical bearing is adopted for the supporting portion C, and a supporting portion structure has been developed which releases the prying force generated during rolling due to the displacement of the spherical bearing. .. That is, in the figure, B is an arm, and a large diameter hole D is formed at the other end in a direction orthogonal to the longitudinal direction of the arm B, and a spherical surface composed of an inner ring E 1 and an outer ring E 2 is formed in the hole D. A bearing E is provided, and an inserting hole Fa having the same diameter as the inserting hole Ea of the spherical bearing E is formed in both legs of the inverted U-shaped stabilizer link F which is laid across the other end of the arm B. Has been done. In the figure, G is a cylindrical spacer, which is a synthetic resin distance spacer having an insertion hole Ga of the same diameter as the insertion hole Ea of the spherical bearing E, and K is for fixing the cab fixed to the stabilizer link F. It is a ring.

Therefore, in order to assemble the support portion C, firstly, the distance spacers G are arranged on the left and right sides of the inner ring E1 and inserted into the stabilizer link F, and thereafter, the stabilizer link F, the distance spacer G, and the inner ring E1. The pin bolt H is inserted into each of the insertion holes Ea, Ga, Fa, and the nut J is fastened to the bolt H via the spring washer I.

[0005]

[Problems to be solved by the device]

 However, in the conventional support structure as described above, when assembling the pin bolt H in the assembling process, the distance spacers G are brought into contact with the left and right sides of the inner ring E1 and the insertion holes of the inner ring E1 and the distance spacer G are inserted. After aligning the axes of Ea and Ga, the spherical bearing E and the distance spacer G are supported so as not to be separated from each other and inserted into the stabilizer link F, and then both the distance spacer G and the stabilizer link F are inserted again. Since the axes of the insertion holes Ga and Fa need to be aligned, the pin bolts H cannot be inserted until after a total of five insertion holes have been aligned, resulting in extremely poor productivity. Further, since the spherical bearing E mounted in the large-diameter hole D of the arm B is in an exposed state, there is a possibility that dust may enter, which deteriorates the durability of the spherical bearing E and causes abnormal noise.

[0006]

[Means for solving problems]

 The present invention has been made to solve the above-mentioned conventional drawbacks, and the distance spacers arranged on the left and right of the spherical bearing mounted in the circular hole formed on the fixed end side of the suspension are circular. The purpose is to make it a shape that can be temporarily set in the hole and also to function as a dust seal for the spherical bearing.The point is that the distance spacer is installed in the circular hole of the suspension equipped with the spherical bearing by elastic deformation of the flange. It is characterized in that it is temporarily fixed and placed in a shackle, and the spherical bearing, distance spacer, and shackle are rotatably supported by pin bolts.

【Example】

 Hereinafter, the present invention will be described in detail with reference to an embodiment shown in FIGS. 1 to 5. FIG. 1 is a partially cutaway front view showing a support structure of a suspension according to the present invention, and FIG. 2 is the same support structure. FIG. 3 is a first assembly process diagram of the support structure main part, FIG. 4 is a second assembly process diagram, and FIG. 5 is a third assembly process diagram.

In the drawings, reference numeral 1 denotes a suspension, and in the embodiment, a stabilizer for connecting a cab and a chassis is shown, and a circular hole 2 formed in a fixed end portion 1A thereof has an insertion hole 3a. A spherical bearing 3 including an inner ring 3A and an outer ring 3B is provided. The lateral width of the spherical bearing 3 is smaller than the lateral width of the fixed end portion 1A, and by disposing the spherical bearing 3 in the central portion of the circular hole 2, the space portions on the left and right of the spherical bearing 3 are arranged. 4 are formed.

Reference numeral 5 denotes a distance spacer arranged on the left and right sides of the spherical bearing 3 in the circular hole 2. The distance spacer is a steel pipe 6 having an insertion hole 5a having the same diameter as the insertion hole 3a of the inner ring 3A. A seal ring 7 made of an elastic material such as rubber is baked on the outer peripheral surface in a concentric circle, and a flange 8 having a diameter slightly larger than the circular hole 2 is provided at one end of the seal ring 7. A chamfer 8a is formed on the front surface side of the flange 8 to facilitate insertion into the circular hole 2.

Reference numeral 9 denotes an inverted U-shaped shackle which is laid across the fixed end portion 1A of the stabilizer 1. The left and right legs of the shackle have an insertion hole 9a having the same diameter as the insertion hole 3a of the spherical bearing 3. Is made. In the figure, 10 is a pin bolt to be inserted into the insertion hole 9a of the shackle 9, 11 is a nut screwed into the pin bolt 10, 12 is a spring washer, and 13 is fixed to the top surface of the shackle 9. It is a ring for fixing to the cab.

The axes of the insertion hole 3a of the bearing 3 and the insertion hole 5a of the distance spacer 5 are automatically aligned. Further, since the circular hole 2 is sealed by the flange 8, the spherical bearing 3 is protected from invasion of dust.

Then, as shown in FIG. 4, the fixed end portion 1 A in which the distance spacer 5 is temporarily set in the circular hole 2 is inserted into the shackle 9, and the distance spacer 5 and the shackle 9 both insertion holes 5 a. , 9a are aligned with each other, and then the pin bolt 10 is inserted into the insertion holes 3a, 5a, 9a of the spherical bearing 3, the distance spacer 5, and the shackle 9, as shown in FIG. When the spring washer 12 is inserted in and the nut 11 is fastened, the assembly is completed as shown in FIG. Since the distance spacer 5 is supported in the circular hole 2 by the elastic deformation of the flange 8, the displacement of the spherical bearing 3 can be easily followed.

Although the cab suspension has been described in the above embodiment, the present invention is not limited to this, and at least the spherical bearing 3 and the pin bolt 10 are used to rotate and rotate like a chassis suspension, a chassis stabilizer, or a torque rod. The same effect can be obtained by applying it to a part where shaking is allowed.
