Description

[Detailed Description of the Invention] The present invention relates to a shock absorber that is interposed between the vehicle body and the axle of an automobile, two-wheeled vehicle, four-wheeled vehicle, etc., and absorbs the shock when driving on a road surface so as not to be transmitted to the vehicle body. The present invention relates to an attachment device for a spring seat for spring suspension attached to the shock absorber.

The suspension spring seat of this kind of shock absorber generally consists of a lower spring seat body 3 fixed to the cylinder 2 side of the shock absorber 1 and an upper spring seat body 5 fitted into the piston rod 4, as shown in FIG. , the spring seat body 5 is held on the piston rod 4 by fitting a cap cover 6 fixed to the piston rod 4, and both spring seat bodies 3,
A spring 7 is suspended between 5 and 5.

In recent years, the upper spring seat body 5 has been designed with a slit 12 having a width slightly wider than the diameter of the piston rod 4, as shown in FIG. have been adopted.

The conventional spring seat body 5 provided with such slits is partially shown in FIG.
A stepped portion is provided at the fitting portion 8 with the cap cover 6, and the inside of the stepped portion extends horizontally, that is, in a direction perpendicular to the axial direction of the piston rod 4. The spring seat body 5 and the cap cover 6 can be fitted together by the end edge of the cap cover 6 coming into contact with the inner peripheral guide surface 9.

However, in the above conventional configuration, the inner peripheral guide surface 9 of the upper spring seat body 5 and the cap cover 6
Although the elasticity of the spring 7 can be supported by the engagement of the spring 7, the slit portion of the spring seat body 5 deforms in the direction of opening due to the spring load when repeatedly subjected to shocks such as when driving on a road or riding a car, and may come off the cap cover 6. There was a risk that the suspended spring 7 would no longer be supported.

The object of the present invention is to provide a suspension spring seat attachment device for a shock absorber that prevents such a risk from occurring and increases the strength of the spring seat.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

As shown in FIGS. 3 and 4, an upper spring seat body 1 is paired with a lower spring seat body 3 fixed to the cylinder 2 of the shock absorber 1.
A stepped part is provided in the fitting part 8 with the cap cover 6 of No. 0, and the inner periphery of the fitting part 8 is fitted with the cap cover 6.
It is bent to the side parallel to the axial direction of the piston rod 4 so that the edge of the cap cover 6 can be fitted onto the outer peripheral surface 11 of the bent part of the stepped part of the spring seat body 10. 13 is the cylinder cover, 14,1
5 is a mounting bracket.

The upper spring seat body 10 is 1 as shown in FIG.
A slit 12 that is slightly wider than the diameter of the piston rod 4 is provided at the location, and when the spring 7 is suspended, the spring seat body 10 is inserted through the slit 12.
When the cap cover 6 is fitted onto the piston rod 4 from the lateral direction using the
It is fitted onto the outer circumferential surface 11 of the inner bent portion. Since the cap cover 6 is fixed to the piston rod 4,
The elasticity of the spring 7 suspended between the spring seat bodies 3 and 10 can be supported by the fixed cap cover 6 via the stepped portion of the spring seat body 10. At this time, the fitting portion 8 of the spring seat body 10 and the cap cover 6 is
Since the cap cover 6 is fitted on the outside of the spring seat body 10, the slit 12 of the spring seat body 10 will not be pushed open by the spring load even if the spring seat body 10 is subjected to shocks such as when driving, and the spring seat body 10 itself will not be pushed open. can be made solid.

In the above embodiment, the upper spring seat body 10 and the lower spring seat body 3 have been described, but this is for convenience of explanation, and the same applies even when upside down, and other aspects depart from the gist of the present invention. Of course, various changes can be made within the scope.

As described above, according to the spring seat mounting device of the present invention, the center side of the spring seat body on the piston rod side provided attached to the shock absorber is bent in a direction parallel to the piston rod axial direction, and the spring seat body is bent outward. Since the end edge of the cap cover fixed to the piston rod is fitted, the cap cover can prevent the slit formed in the spring seat body from widening, and the spring seat body will not come off from the cap cover. It can increase the strength of the body itself.
