Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for under brackets and other brackets in hydraulic shock absorbers.

Conventionally, as this type of device, for example, Fig. 1 and Fig. 2
As shown in the figure, a type in which a cylindrical under bracket c is fixed to the outer surface of a lower cap b on the end face of a cylindrical shock absorber main body a is known. Generally, a spherical bulge surface d is formed at the center, and the bracket c is fixed by coming into contact with this surface.In such a structure, the bracket c is in point contact with the surface d. However, this is accompanied by the disadvantage that it is difficult to obtain good fixation between the two.

The purpose of the present invention is to obtain a device free of such inconveniences, and the main body of the shock absorber 1 is cylindrical.
In the case of a type in which a cylindrical bracket 3 is superimposed on the outer surface of the cap 2 on the end surface of the cap 2 and fixed thereto by projection welding or other means, the outer surface of the cap 2 is preliminarily press-formed or otherwise attached.
At least one pair of left and right protrusions 4, 4 parallel to the axis of the
is formed, and the bracket 3 is brought into contact with the protrusions 4, 4 and fixed thereto by projection welding or other means.

FIGS. 3 and 4 show one example, in which the pair of protrusions 4, 4 extend in parallel to each other over substantially the entire length of the bracket 3. In the illustrated example, the cap 2 is prepared separately from the main body 1 and then fitted onto it and fixed by welding or other means, but the present invention is not limited to this. It is also possible to form it in one piece, thus making it possible to further increase the overall strength.

The pair of protrusions 4, 4 may be arranged in two stages, one at the front and the other at the rear, as shown in FIG.

In this way, according to the present invention, at least one pair of right and left protrusions 4, 4 are formed on the outer surface of the cap 2, parallel to the axis of the bracket 3, and the bracket 3 is
The bracket 3 is fixed in contact with the protrusions 4, 4, and the bracket 3 can obtain a relatively large contact area with the protrusions 4, 4 to obtain good welding by, for example, projection welding. Moreover, in this case, the thick winding between the bracket 3 and the protrusions 4 allows for heat balance during energization, which has the effect of effectively preventing welding defects.
