JPH11278003A - Combination structure of wheel cap with aluminum disk wheel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily attach and detach a wheel cap without breaking it by fitting and fixing the upper portion of an anchor-shaped holder claw into a deep hole and fitting the lower portion of the holder claw fixed to a holder of the wheel cap into a cap attaching hole of a disk wheel. SOLUTION: A resin made wheel cap 5 comprises of a wheel cap body 6 and a holder 7 formed integrally on its back surface, and the position of the holder 7 is corresponded to a cap attaching hole 4 of a wheel. The holder 7 is provided with a deep hole 8 used for fitting and fixing the upper portion of a holder claw. The holder claw consists of the upper and lower portions, and the lower portion has a structure so that it is fitted and fixed into the cap attaching hole 4 of a disk wheel 1. Therefore, in a combination structure of the wheel cap 5 with the aluminum disk wheel 1, the wheel cap can be easily removed in the case of burst or an exchange of a tire.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination structure of an aluminum disk wheel and a resin wheel cap, and more particularly to a structure in which a thin and lightweight wheel cap is designed to be easily attached and detached.

[0002]

2. Description of the Related Art Conventionally, in an aluminum disk wheel (hereinafter simply referred to as an aluminum wheel), a design is applied to the aluminum wheel itself. So-called caps have been used. However, recently, the structural analysis of aluminum wheels has progressed, and the design of aluminum wheels has become simpler, so the idea was to cover the entire wheel with a thin wheel cap.

[0003] In order to attach the wheel cap to the disk wheel, a holder claw is required. The present applicant has proposed a mounting structure of a half-size wheel cap in which an anchor-shaped holder claw is fitted in a mounting hole of a disk wheel in Japanese Utility Model Application Laid-Open No. 59-49503. Although this structure is general and not shown, a mounting hole is provided in a bead portion between the hub nut holes of the desk wheel, and a projection is provided on the back surface of the wheel cap to form a holder, and the holder has a spring. An anchor-shaped holder claw formed of a steel plate is fixed thereto.

[0004]

However, even if the structure including the mounting portion of the wheel cap using the anchor-shaped holder claws described above is applied to a wheel cap thinned for an aluminum disc wheel as it is. Since the disk wheel is formed in a spoke shape, the strength of the disk wheel is reduced. If you try to attach it to these spokes, the outer edge of the wheel cap will be far apart from the holder claw. However, there has been a problem in that the wheel cap is elastically deformed and is difficult to remove, or the outer edge of the wheel cap is damaged.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a combination of a wheel cap and an aluminum disc wheel which can be easily attached and detached without damaging the wheel cap, even if the wheel cap is made thinner. It is intended to provide a structure.

That is, according to the combination structure of the wheel cap and the aluminum disc wheel of the present invention, the boss portion 3 is provided at a plurality of places at intervals on the rim flange portion 1b of the disc wheel 1, and the boss portion 3 A cap mounting hole 4 for fitting a claw is provided. On the other hand, a resin wheel cap 5 is provided with a holder 7 at a position corresponding to the cap mounting hole 4 on the back surface of the cap body 6, and the holder 7 is provided from below. Deep hole 8 for holder nail mounting
The upper portion 9a of an anchor-shaped holder claw 9 is fitted and fixed to the deep hole 8, and the lower portion 9b of the holder claw fixed to the holder 7 of the wheel cap is attached to the cap of the disc wheel. It is characterized in that it is fitted in the mounting hole 4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A combination structure of a wheel cap and a disc wheel according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view (AA sectional view of FIG. 5) showing an embodiment of the present invention. FIG.
FIG. FIG. 3 is an enlarged perspective view showing a state in which a holder claw 9 is attached to the holder 7 of the wheel cap. FIG. 4 is a front view of the wheel cap of the present invention. FIG.
1 is a front view of a disk wheel according to the present invention.

As shown in FIG. 5, an aluminum disk wheel 1 is designed in consideration of weight reduction, and is provided with a spoke-shaped disk portion 1a and a rim portion 1b provided integrally. The rim portion 1 of the disk portion 1a
A boss 3 is formed at the boundary of b, that is, at the root of the disk. Further, as shown in FIG. 2, the boss 3 is provided with a cap mounting hole 4 for fitting the lower end 9a of the holder claw 9 therein.

The resin wheel cap 5 is shown in FIGS.
As shown in FIG. 4 and FIG.
It consists of a holder 7 integrally formed on the back surface,
The position of the holder 7 is the cap mounting hole 4 of the wheel.
It is made to correspond. The holder 7 is provided with a deep hole 8 for fitting and fixing an upper portion 9a of a holder claw 9 described later.

As shown in FIG. 3, the holder claw 9 is composed of the upper part 9a and the lower part 9b, and the lower part 9b is fitted and fixed in the cap mounting hole 4 of the disk wheel. It has become. In the present invention, the shape of the holder nail is not limited.

[0011]

The combination structure of the wheel cap and the aluminum disc wheel of the present invention is a dressing cap for an aluminum wheel. Even if the cap body is formed thin, the holder claw is located near the outer edge of the wheel cap. , The degree of elastic deformation when prying with a driver or the like is small, and the wheel cap can be easily removed without damaging the wheel cap when puncturing or changing tires.
