Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dirt prevention cover for a vehicle wheel for preventing dust from a brake pad of a vehicle wheel from adhering to an outer surface of the wheel.

[0002]

2. Description of the Related Art FIG.
It is known to attach a dust cover 56 shown in FIG. The dust cover 56 has a hole in the center, a plurality of bolt holes 59... Formed on the outer circumference of the hole, and a steel disk portion 57 formed on the same circumference. A peripheral rotor 58 is integrally fixed to form a substantially disk-like shape, and this cover is, for example, a brake rotor constituting a disc brake of a wheel 50 in which a rim portion 51 and a disc portion 52 are integrally formed. A bolt 55 is attached to the center bore of the disk portion 52 using the bolt holes 59 so as to be substantially parallel to the outside of the bolt 53. The dust cover 56 receives the dust coming out of the brake pad by the operation of the brake caliper 54 when the brake acts on the rotating wheel 50 and prevents the dust from being scattered outward from between the disk portions 52 of the wheel 50. This prevents the outer surface of the wheel 50 from becoming dirty with dust and deteriorating the appearance.

[0003]

This dust cover 56
Is a so-called full cover type, which is originally provided so as to cover almost the entire surface inside the wheel 50. The heat generated by the operation of the disc brake is dissipated by the steel plate portion 57 and the outside of the disk portion 57. Although an appropriate number of ventilation holes (not shown) provided on the outer peripheral portion 58 made of a soft rubber are radiated, heat generated when the brake is actuated is not sufficient with only these ventilation holes. In addition to the drawback that the heat radiation effect is poor, the structure of the dust cover 56 itself is complicated and the number of manufacturing processes required for the dust cover 56 is inevitably high, and the cost is inevitably high. Has been included.

Since the dust cover 56 is a full cover type as described above, the designed brake system in the wheel is hidden and cannot be seen from the outside.
The problem is that it doesn't match well with the modern tide that prefers to see it from the outside.

In the case of a large brake caliper having a large amount of protrusion, the dust cover 56 often cannot be mounted due to interference.

Furthermore, the presence of the dust cover 56 may require changing the wheel offset (the distance between the center line of the rim width and the mounting surface of the hub) depending on its thickness and shape. Due to the stop, there are various problems that the dust cover 56 cannot be taken out alone.

[0007] The inventors of the present invention have conducted intensive studies to improve the above-mentioned problems of the wheel provided with the conventional dust cover, and as a result of the diligent research test, the dust coming out of the brake pad was subjected to the centrifugal force of the rotating wheel. Since it scatters in the circumferential direction inside the wheel, there is no need to dare to cover the entire inside of the wheel, and by arranging the cover only in the direction in which the dust scatters, the above-mentioned various problems can be solved advantageously. They have found that they can do so and have completed the anti-smudge cover for automotive wheels of the present invention.

[0008]

According to a first aspect of the present invention, there is provided an automobile comprising a donut-shaped plate having a predetermined annular width which is mounted on a disk portion near a well of a rim portion of an automobile wheel. It is a dirt prevention cover for the wheel.

According to a second aspect of the present invention, the cover is bolted to the disk portion by bolt holes provided at predetermined intervals near an outer peripheral edge of the plate. It is a dirt prevention cover of the above-mentioned automobile wheel.

According to a third aspect of the present invention, there is provided the automobile wheel dirt prevention cover according to the first aspect, wherein the cover is formed by dividing a donut-shaped plate.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The dirt preventive cover for an automobile wheel according to the present invention comprises a donut-shaped plate having a predetermined annular width, which corresponds to a deepest recess formed in a rim portion of the wheel. The wheel of a car currently used is basically a one-piece structure in which the entire wheel is integrated, and the rim and disk are made separately. Rim part is divided into an outer rim part and an inner rim part, and a disc part separately formed is connected to these parts. The dirt prevention cover of the present invention can be applied to any of them.

The means for attaching the cover is not particularly limited as long as the cover can be securely attached. Preferably, the cover is bolted to a disk portion near the well of the rim portion. For example, for a one-piece wheel, a predetermined interval is maintained at a disc portion near the well of the rim portion, and the vicinity of the outer peripheral portion of the donut-shaped plate is directly bolted to the two-piece structure and three-piece structure. The above-mentioned plate can be easily attached to a wheel having a structure by bolting a portion near the outer peripheral edge of the plate using a bolt used for connecting the rim and the disk. More preferably, the cover can be bolted by preventing the cover from moving outward by using a projection which also serves as a decorative part on the inner periphery in the middle of the disk portion as a stopper.

The cover can be made of various materials such as non-ferrous metal, steel plate, plastic plate, etc., and preferably a cover formed to a predetermined size by processing a thin metal plate such as aluminum. The size is appropriately determined according to the size and shape of the wheel to be applied. This cover may be obtained by dividing the donut-shaped plate, and the division may be arbitrary. However, it is desirable that the plate be divided into a fan shape through the diameter.

[0014]

The automobile wheel dirt prevention cover according to the present invention comprises a donut-shaped plate having a predetermined annular width, which is mounted on a disk portion near a well of a rim portion of the automobile wheel, and is provided during driving of the automobile. A brake caliper is pressed against a brake rotor that is rotating integrally with the wheel when the brake is actuated and dust generated from the brake pad due to friction is received by the donut-shaped plate of the cover to appropriately prevent the wheel from being soiled, It is possible to always maintain a clean state where no dust adheres to the outside of the wheel.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a cover for preventing contamination of a vehicle wheel according to the present invention. FIGS. 1 and 2 show an example of a dirt prevention cover according to the present invention. The cover 1 is made of a donut-shaped plate having a predetermined annular width in which a circular hole 2 is formed in the center by processing a thin plate of a lightweight metal such as aluminum. A plurality of bolt holes 3, 3, 3,... Are formed at equal intervals in the vicinity of the outer peripheral edge of the plate, that is, on a concentric part slightly inward from the outer peripheral edge. Although this cover 1 is shown in a flat plate shape in FIG. 2, it can be used by being appropriately bent in accordance with the shape of the wheel to be applied in actual use.

FIG. 3 shows a state in which the cover 1 is mounted on the one-piece wheel 4 as described above, and the cover 1 has a deep dent formed in the rim portion 5 of the one-piece wheel 4. The bolts 8, 8 are held at appropriate intervals at the outer edge of the disk portion 7 near the well 6 corresponding to

It is desirable to mount the plate so that its annular inner peripheral edge is parallel to the brake rotor 10 of the disc brake or slightly toward the brake rotor 10, but in some cases, in a direction away from the brake rotor 10. It may be worn facing.

In a vehicle having the cover 1 having such a structure attached to the wheel, when the brake is operated during driving and the brake caliper 9 is pressed against the brake rotor 10 which rotates integrally with the wheel 4, the brake caliper is caused by friction. Dust is generated from the brake pad 9 and the dust scatters around the inside of the wheel 4 in the circumferential direction by centrifugal force. The scattered dust hardly jumps out of the hole 2 formed in the center of the cover 1 due to the centrifugal force, and is received by the annular plate portion arranged in the circumferential direction, and extremely appropriately prevents the wheel 4 from being soiled. The outside of the wheel 4 can always be maintained in a clean state free of dust.

The cover 1 has a hole 2 in the center, and the outer annular plate portion covers only the portion of the wheel 4 where dirt is most likely to adhere. 2, heat can be radiated extremely efficiently, and thereby an excellent heat radiating effect can be exhibited.

The hole 2 provided in the center of the cover 1 allows the brake system inside the wheel 4 to be clearly seen from the outside, so that the modern tide, which prefers to see the designed brake system inside the wheel, from the outside. You can match well.

Further, by adjusting the annular width of the plate, a substantial space between the wheel 4 and the brake system can be eliminated.

Such a cover 1 is formed of a thin plate, and is extremely advantageous because the hole 2 does not interfere with a large-sized brake caliper having a large amount of protrusion.

Further, since the thickness of the cover 1 is made as small as possible to form a donut-shaped plate having a predetermined annular width,
It is extremely lightweight and also excellent in that it is not necessary to consider changes in wheel offset.
