Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for connecting a shock absorber and a body used in an automobile suspension system.

With the conventional shock absorber and body fastening structure, the shock absorber rod rotates due to vibrations and impacts during driving, so when the actuator is attached to the head of the rod using a damping force adjustable shock absorber, etc. If the wires were simply wired without taking any special measures, the lead wire coming out of the actuator would wind around the actuator, be pulled, and eventually break. If the lead wire is cut, the actuator will lose its function, making it impossible to adjust the damping force, making it impossible to achieve its original purpose.

The present invention is intended to solve the above-mentioned conventional disadvantages, and the rod of the shock absorber does not rotate relative to the body at the joint between the shock absorber and the body, or it rotates to a certain extent but is stopped from rotating further. As a result, the actuator attached to the head of the rod, such as a shock absorber with adjustable damping force, will no longer rotate relative to the body, which may cause the lead wire connected to the actuator to wrap around or break. This is to ensure sufficient reliability of the damping force adjustment mechanism.

In the fastening structure of the present invention, a cushion retainer is arranged above a body so as not to rotate with respect to the body, and a cushion having an irregularly shaped surface is connected to a cushion retainer and an actuator each having an irregularly shaped surface corresponding to the irregularly shaped surface. placed between the air brackets,
The present invention is characterized in that the shock absorber is prevented from rotating more than a predetermined amount with respect to the body by inserting a shock absorber rod having an irregularly shaped tip into an irregularly shaped hole provided in the actuator bracket.

In the present invention, in order to arrange the cushion retainer so as not to rotate with respect to the body, as will be explained in detail in the following embodiment, the retainer should be placed between the body and the cushion retainer.
It is also possible to provide a pawl plate that engages at a certain point, to engage with a modified surface provided on the upper side of the body and a modified surface of the retainer, or to fix the retainer directly to the body with bolts. Furthermore, rotation of the retainer may be prevented by an actuator cover. Furthermore, the actuator and shock absorber are also prevented from rotating relative to the body by directly preventing rotation of the actuator bracket to the body and by preventing rotation of the actuator bracket and the shock absorber rod.

The present invention will be explained below with reference to Examples.

FIG. 1 is a sectional view showing the basic form of the fastening structure of the present invention, and FIGS. 2 to 5 are views showing the specific structure of the first embodiment.

In the first embodiment, as a cushion retainer 1 located above a body 5, claw plates 1a are provided in two consecutive locations as shown in FIGS. 2 and 3.
a is configured so that it comes into contact with the body 5, and the body 5
This is an example using a device that is designed to stop after a certain amount of rotation. The cushion retainer 1 also has an irregularly shaped surface in the center, and on this irregularly shaped surface is placed a cushion 2 having the shape shown in FIG. The actuator bracket 3 having the actuator bracket 3 is placed on the cushion 2. In this way, the retainer 1, the cushion 2, and the actuator bracket 3 are assembled by the irregularly shaped surfaces, so that the actuator bracket 3 does not rotate relative to the body 5. As shown in FIG. 4, the shock absorber rod 4 can be stopped from rotating by inserting the shock absorber rod 4 whose tip end has a similar cross-sectional shape into a hole 3a having two sides provided in the actuator 3. do.
In FIG. 1, 10 indicates a nut.

With the above structure, the actuator 8 and the shock absorber rod 4 are integrally prevented from rotating with respect to the body 5, and there are no drawbacks such as the lead wire 9 wrapping around the actuator or being pulled and breaking. does not occur.

The second embodiment is basically the same as the first embodiment, and the relationship between the retainer 1 and the body 5 is shown in FIG.
As shown in B, this is an example in which the rotation of the retainer 1 relative to the body 5 is stopped by making the body hole and the retainer spigot part irregularly shaped. 6 indicates a shock absorber.

The third embodiment is basically the same as the first embodiment, but the retainer 1 is connected to the bolt 1 as shown in FIG.
1 is an example in which it is tightened and fixed to the body 5.

In the fourth embodiment, a cover 7 attached to the cushion retainer 1 is used to prevent rotation. The cushion retainer 1 is engaged with the cover 7 as shown in FIGS. 8A and 8B to prevent rotation, or the cushion retainer 1 is fastened to the cover 7 with bolts or the like. Furthermore, as shown in FIG. 9, the over 7 may be made into an irregular shape to prevent it from rotating relative to the body, or may be tightened with bolts or the like. The other structure is the same as that of the first embodiment.

In the fifth embodiment, the retainer 1 has the structure of any one of the first to fourth embodiments to prevent rotation relative to the body, and the retainer 1 is bent upward as shown in FIG. Provide one to three matching claws 1b, and attach the actuator bracket 3 to these claws 1b.
to stop rotation. With such a structure, the cushion 2 does not have to have an irregular shape. The actuator bracket 3 and the shock absorber rod 4 are prevented from rotating by the method of the first embodiment.

In the fourth embodiment, as shown in FIG. 11, a part of the actuator bracket 3 is lengthened and bent downward to form a claw that engages with the body 5, and is similar to the retainer 1 and body 5 in the first embodiment. This is an example in which the actuator bracket 3 is stopped from rotating relative to the body 5 by the method. In this case, it is best to provide 1 to 3 claws on the actuator bracket 3.
Further, as can be seen from the figure, since the retainer 1 is also prevented from rotating by the claws, the cushion 2 may not have to be of an irregular shape in some cases. The relationship between the actuator bracket 3 and the shock absorber rod 4 is the same as in the first embodiment.

Although each embodiment has been described above, the present invention is not limited to these examples.

In the present invention, since the shock absorber is fastened to the body in a manner that prevents it from rotating as described above,
Unlike conventional shock absorbers, the shock absorber rod and actuator do not gradually rotate while the vehicle is running, and therefore the lead wires do not get twisted or disconnected. It has many advantages, such as making the function sufficiently reliable.
