Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rust-preventing cover used for rust-proofing a disc plate of an automobile disc brake.

(Prior art) Although the inner surface of the disc plate of an automobile disc brake is covered with a dust cover, the outer surface is exposed inside the wheel and may rust over time. . Particularly when automobiles are transported as cargo on a ship, there is a risk that the outer surface of the disk plate will be exposed to the influence of sea breeze and may rust at an early stage. If rust occurs on the disc plate, the friction pads of the brake will wear out faster and the coefficient of friction will decrease, so there is concern that braking performance will deteriorate. Therefore, conventionally, a rust prevention cover is attached to the disk plate before transportation to prevent rust from forming, and the rust prevention cover is removed after transportation.

An example of this type of anti-corrosion cover has been disclosed in Japanese Utility Model Application Publication No. 55-97234.
This anti-corrosion cover has slits or grooves in two places facing the outer surface of the disk plate, and has slits or grooves in multiple places on the outer periphery that are engaged with the outer periphery of the dust cover when it is installed. It has two pieces. The anti-corrosion cover is attached by engaging the engaging piece with the outer periphery of the dust cover, and by manually pulling the vicinity of the slit or groove to create a border between the slit or groove. It was designed to be removed from the dust cover by breaking it into two pieces.

However, with the above-mentioned conventional rust-proof cover, it is troublesome to engage the engaging piece with the outer periphery of the dust cover when installing it, and it lacks workability. Also, when removing it, it is difficult to pull the area near the slit or groove. Otherwise, there was an inconvenience that it could not be easily broken as expected.
In addition, the anti-rust cover contains moisture and swells, causing interference with the wheel and reducing the anti-rust effect.

(Purpose of the invention) In view of the above-mentioned problems, the present invention was devised to eliminate the drawbacks of the conventional cover, and its purpose is to provide a rust-proof cover that can be easily attached and detached and has a high rust-prevention effect.

(Structure of the invention) In order to achieve the above object, the rust-proof cover of the present invention is composed of a partially cut-out annular member, which is held on a disk plate with a rubber band, and the rust-proof cover of the present invention is is provided with a clip that is secured to the rubber band.

(Effect of the invention) Since the present invention is constructed as described above, the anti-rust cover is attached to the dust cover by sandwiching the caliper, fixed by the tension of the rubber band, and the clip is attached to the rubber band. It is easy to do just by locking, and since it is locked at three points, the installation is reliable and the rust prevention effect is improved. Further, even if the rust-proof cover expands due to moisture, it can be prevented from deforming outward, and interference between the rust-proof cover and the wheel can also be prevented. To remove the rust prevention cover,
It can be easily removed from the dust cover by simply pulling the clip provided on the rust-proof cover by hand.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

As an example is shown in Figures 1 and 2,
The rust-preventing cover 1 is constituted by an annular member in which a portion of resin or pressboard (cardboard) impregnated with resin is cut out. Further, a rubber band 3 is attached to the anti-rust cover 1 between two locations 2a and 2b on the outer periphery of the annular member spaced apart from both notched ends 1a and 1b. As a means of fixing the rubber band 3, for example, staples are used, but other means are used to fix the rust-proof cover 1.
Two stepped portions may be provided on the outer periphery of the rubber band 3 and the rubber band 3 may be fitted therein.

Next, FIGS. 3, 4, and 5 show the state in which the rust preventive cover 1 is attached to the disk plate 4.

In FIG. 3, 5 is a shaft, and 6 is a disc brake attached to the shaft 5. The disc brake 6 includes a disc plate 4 and a caliper installed opposite a part of the disc plate 4, and the caliper includes a friction pad 8 for pinching the surface of the disc plate 4 and a piston 9 for actuating the pad. have. Also,
The inner circumferential surface 4a of the disk plate 4 is covered by the dust cover 10 attached to the shaft 5, while the outer circumferential surface 4b of the disk plate 4 is covered by the anti-rust cover 1. It is being said.

When the anti-corrosion cover 1 is brought into contact with the outer periphery of the dust cover 10, as shown in FIG.
b, and the rubber band 3 is engaged with the dust cover 1.
It spans outside of 0. The rubber band 3 is held in place by a clip 11 provided on the anti-rust cover 1. The rust preventive cover 1 thus attached covers almost completely the outer surface 4b of the disk plate 4, as shown in FIG. In addition,
In FIG. 3, reference numeral 12 indicates a wheel attached to the shaft 5 so as to enclose the disc brake 6 and the dust cover 10.

Next, the work of attaching the anti-rust cover 1 to the dust cover 10 and the work of removing it from the dust cover 10 will be explained.

To install the anti-rust cover 1, use the wheel 12.
is carried out without being attached to the shaft 5. That is, both cut ends 1a, 1 of the rust-proof cover 1
At the same time, insert the both ends 7a and 7b of the caliper with
Then, the rubber band 3 is stretched around the outside of the dust cover 10, and the rubber band 3 is attached to the outside of the dust cover 10 using the clip 11 provided on the rust-proof cover 1.
to lock. The installation work is now complete. By providing the clip 3, it is locked at three points, so the attachment is reliable and the rust prevention effect is improved. Moreover, even if the rust-proof cover 1 expands due to moisture, it can be prevented from deforming outward, and interference between the rust-proof cover 1 and the wheel 12 can also be prevented.

On the other hand, when removing the rust prevention cover 1 from the dust cover 10, since the wheel 12 is already attached to the shaft 5, insert your hand from the inside of the wheel 12 (lower side in Fig. 3) and remove the rust prevention cover. Pull the clip 10 provided on the cover 1. In this way, since the fixed part of the rubber band 3 to the rust-proof cover 1 is stapled, for example, it can be easily separated, and the rust-proof cover 1 comes off from the dust cover 10 and is pulled out to the outside of the wheel 12. It will be done.

The above embodiment is an example in which one rubber band 3 is used, but in order to more firmly fix the rust prevention cover 1 to the dust cover 10, auxiliary rubber bands are separately provided at both notched ends 1a of the rust prevention cover 1. , 1b.

As detailed above, the anti-corrosion cover according to the present invention can be easily attached to and removed from the dust cover, and is locked at three points, so the attachment is reliable and the anti-rust effect is improved. . Also,
Even if the rust-proof cover expands due to moisture, it can be prevented from deforming outward, and interference between the rust-proof cover and the wheel can also be prevented.
