Description

[Detailed Description of the Invention] This invention relates to a rust-preventing cover used for rust-proofing a disc plate of an automobile disc brake.

Although the inner surface of the disc plate of an automobile disc brake is covered with a dust cover, the outer surface of the disc plate is exposed inside the wheel and may rust over time. Particularly, when a car is 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. When rust occurs on the disc plate, the friction pads of the brake wear quickly and the coefficient of friction decreases, resulting in a problem of reduced braking performance. Therefore,
Conventionally, a rust prevention cover is attached to a disk plate before transportation to prevent rust, 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 during installation, and it lacks workability. If it was not stretched, it would not break as easily as expected, which was an inconvenience.

This invention was made in order to eliminate the above-mentioned conventional drawbacks, and the purpose is to provide a rust-proof cover that can be easily and accurately attached and detached.

In order to achieve the above object, the anti-rust cover of this invention is constituted by an annular member with a part cut out, and both of the cut ends form an engaging part that engages with the end of the caliper. However, a rubber band is provided between the two engaging parts to be hooked onto the caliper and to clamp the caliper together with the two engaging parts.

Embodiments of this invention will be described below with reference to the drawings.

As an example is shown in Figures 1 and 2,
The anti-corrosion cover 1 is made of a circular ring-shaped member with a part cut out, such as a resin or a press board (cardboard) impregnated with resin, and both cut ends are
an engaging portion 1a that engages with an end of a caliper, which will be described later;
1b. And these engaging parts 1
Both ends 2a and 2b of a rubber band 2 are fixed to a and 1b, respectively. For example, stapling is used as a fixing means in this case, but
Other than this, a method may also be used in which the ends of the rubber band 2 are inserted into slits formed in both the engaging portions 1a and 1b. In addition, the anti-rust cover 1 has both of the above-mentioned engaging portions 1.
An auxiliary rubber band 3 is attached between two locations on the outer periphery of the annular member spaced apart from a and 1b. This auxiliary rubber band 3 is fixed to the annular member by the same means as in the case of the rubber band 2 described above.

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

In FIG. 3, 4 is a shaft, and 5 is a disc brake attached to the shaft 4. The disc brake 5 includes a disc plate 6 and a caliper 7 disposed opposite a part of the disc plate 6. The caliper 7 includes a friction pad 8 for sandwiching the surface of the disc plate 6, and a friction pad 8 for operating the disc plate 6. It has a piston 9. Also,
The inner circumferential surface 6a of the disk plate 6 is covered by the dust cover 10 attached to the shaft 4, while the outer circumferential surface 6b of the disk plate 6 is covered by the anti-rust cover 1. It is being said.

When the anti-rust cover 1 is brought into contact with the outer circumferential portion of the dust cover 10, as shown in FIG.
7b, the rubber band 2 is hooked to the caliper 7, and the rubber band 2 and both engaging parts 1a, 1
The caliper 7 is held between the caliper 7 and the dust cover 10 by the caliper b. The auxiliary rubber band 3 is stretched around the outside of the dust cover 10. The above auxiliary band 3 connects the anti-rust cover 1 to the dust cover 10.
The auxiliary band 3 may be omitted. The rust preventive cover 1 attached in this manner almost completely covers the outer surface 6b of the disk plate 6, as shown in FIG. In addition, in FIG. 3, 11 indicates a wheel attached to the shaft 4 so as to enclose the disc brake 5 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.

The installation work of the anti-rust cover 1 is carried out in a state where the wheel 11 is not attached to the shaft 4. That is, both engaging portions 1a of the rust-proof cover 1,
1b between both ends 7a and 7b of the caliper 7, and at the same time, attach the anti-rust cover 1 to the dust cover 1.
0, the rubber band 2 is pulled and hooked onto the caliper 7, and the auxiliary rubber band 3 is stretched around the outside of the dust cover 10. The installation work is now complete.

On the other hand, when removing the rust prevention cover 1 from the dust cover 10, since the wheel 11 is already attached to the shaft 4, insert your hand from the inside of the wheel 11 (lower side in Fig. 3) and remove the rust prevention cover. Pull cover 1. In this way, since the fixed portions of the rubber band 2 and the auxiliary rubber band 3 to the rust prevention cover 1 are stapled, for example, they can be easily separated, and the rust prevention cover 1 will come off from the dust cover 10 and the outside of the wheel 11 will be removed. It is stretched out. In this case, any part of the rust-proof cover 1 may be grabbed.

As detailed above, the anti-rust cover of this invention can be easily attached to the dust cover by simply inserting the caliper between both engaging parts of the anti-rust cover and hooking the rubber band onto the caliper. In addition, the tension of the rubber band makes the attachment firm. Furthermore, the anti-corrosion cover can be easily removed from the dust cover by simply pulling on any part of the cover by hand.
