Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting bracket for mounting a tube of a hydraulic shock absorber on a vehicle body or a wheel.

[0002]

2. Description of the Related Art Conventionally, as a mounting bracket for a hydraulic shock absorber, a main bracket fixed to an outer peripheral surface of a tube of the hydraulic shock absorber and a sub-bracket having a substantially U-shaped cross section is fixed from inside to a main bracket having a substantially U-shaped cross section. Are known.

In such a mounting bracket,
As shown in FIG. 5A, the main bracket 101 and the sub-bracket 102 formed with the welding projection 102a are combined, and as shown in FIG. 5B, the main bracket 101 and the sub-bracket 102 are fixed by projection welding. Then, the end of the bracket, which is the bracket mounting portion, is lightly press-fitted, loosely fitted or fitted into the bracket assembled body, and then welded and fixed.

[0004]

However, in the above-mentioned mounting bracket, a process for shifting from a pressing process to a welding process is required to fix the main bracket and the sub-bracket by projection welding. In addition, since they are fixed by welding, rust is easily generated by the oxide scale due to welding, penetration of welding cannot be confirmed, and thermal distortion due to welding may occur.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a caulking hole is formed in a main bracket constituting a bracket assembly, and a sub-bracket is provided in the caulking hole of the main bracket. The crimping convex portion formed in the above was fitted and crimped.

[0006]

[Function] Since the main bracket and the sub-bracket are fixed by caulking, after each bracket is manufactured in the pressing process, it can be fixed in the same process.
The disadvantages associated with welding are eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a front view of a main part of a vehicle equipped with a hydraulic shock absorber to which the mounting bracket according to the present invention is applied, FIG. 2 is a perspective view of the mounting bracket, and FIG. FIG. 4 is a sectional view of a main part, and FIG. 4 is an explanatory view for explaining the manufacture of the mounting bracket.

In FIG . 1, a strut type damper 1 as a hydraulic shock absorber has a mounting bracket 3 fixed to a lower outer peripheral surface of an outer tube 2 and a suspension spring 4 disposed on an upper outer peripheral surface. The upper part of the damper 1 is mounted on the vehicle body 5, and the lower mounting bracket 3 is mounted on the knuckle arm 7 of the wheel 6. An axle 8 is connected to the wheel 6, and a lower part of the knuckle arm 7 is a ball joint 9
And a link 10 to the vehicle body 5 side.

As shown in FIG. 2, the mounting bracket 3 has a main bracket 12 having a substantially keyhole-shaped cross section in a direction perpendicular to the axial direction, and a sub-bracket 13 having a substantially U-shaped cross section in a direction perpendicular to the axial direction. Be fixed.

The main bracket 12 includes the outer tube 2.
And a substantially cylindrical tube holding portion 14 through which the holes are inserted, and mounting portions 15 and 15 mounted on the wheel side are integrally formed by press working. The sub-bracket 13 is formed by integrally forming a tube sub-holding portion 16 for supplementing a cut portion of the main bracket 12 and sub-attaching portions 17, 17 for fixing to the attaching portions 15, 15 of the main bracket 12.

Before fixing the main bracket 12 and the sub-bracket 13 to the mounting bracket 3, FIG.
(A) As shown in FIG.
5, a caulking hole 15a is formed, and a caulking convex portion 17a that can be fitted into the caulking hole 15a is formed in the sub-mounting portion 17 of the sub-bracket 13.

In order to manufacture the mounting bracket 3, as shown in FIG.
The mounting portions 15, 15 of the main bracket 12 are closed and the mounting portions 15, 15 of the main bracket 12 are closed as shown in FIG. The caulking convex portion 17a of the sub mounting portion 17 of the sub bracket 13 is fitted into the sub bracket 15a.

Then, as shown in FIGS. 3 (c) and 3 (b), the crimping projections 17a of the sub-bracket 13 are pressed with a punch or the like to form the crimping holes 15a of the main bracket 12.
By squeezing into a plane, the mounting portion 15 of the main bracket 12 and the sub-mounting portion 17 of the sub-bracket 13 are caulked and fixed to form a bracket assembly (mounting bracket 3).

As described above, the mounting bracket 3 of the present invention
Can be all manufactured by a pressing process, eliminating a welding process such as projection welding.

[0015]

[Effects of the Invention] As described above, according to the present invention,
The main bracket and the sub-bracket are fixed by caulking, so each bracket can be fixed in the same process after producing each bracket in the pressing process, reducing costs and reducing rust like welding. There is no problem such as generation of heat deformation and heat generation.
