[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double disk structure of an assembling type vehicle wheel.

[0002]

2. Description of the Related Art Automobile wheels composed of an assembly of a wheel disk and a tire supporting rim are well known, but the disk has a literally flat disk saucer shape as a whole. The three-dimensional impression or profound feeling of the ventilation shaped pattern that will be revealed from now on is poor.

That is, the conventional wheel disk has a so-called single structure as a whole, and the thickness of the plate-like support member is set to a large dimension, or the support member is bent or a rib bulging from the plate surface is used. In addition to achieving the required strength, only the ventilation pattern is shaped, so it must be monotonous as its modeling beauty, and to obtain interesting changes that should be integrated with that of the car body, There are certain limits.

[0004] Such a problem is not drastically improved even if, for example, a wheel cap is attached to the entire wheel disc or a center cap is locally attached to the center of the wheel disc. Moreover, even if such caps have excellent modeling beauty,
Since it is an accessory, it does not play any role in enhancing the strength of the disc itself or increasing the tire supporting rim.

In this regard, the inventor of the present invention has previously proposed Japanese Patent Application Laid-Open No. 58-185302 as an invention for obtaining a wheel disk having a three-dimensional effect, a solid feeling, and a high strength on a formed pattern. As a result, the intended purpose can be achieved for the time being, but the disc is an integral product, and it is still the same as a single structure, so the front wall and the rear wall have to be cast integrally. Not get
It cannot be manufactured by forging from light alloys or other plastic working.

In addition, it is completely impossible for interchangeable wheel manufacturers, dealers, users, and the like to change the pattern of the front wall and the rear wall and then use them after changing the combination.

SUMMARY OF THE INVENTION The present invention is intended to solve such a problem. For this purpose, an adapter ring is attached to a hub of an axle by a first bolt and a nut, and a wheel main body is attached to the adapter ring. The center part of the disk is attached by the second bolt, and the peripheral part of the main disk is also assembled by the tire supporting rim and the third bolt / nut, and in the middle band between the central part and the peripheral part of the main disk, In an assembling vehicle wheel provided with a fixed ventilation pattern,

A sub disk separate from the main disk is prepared, and a ventilation molding pattern different from the ventilation molding pattern of the main disk is applied to an intermediate band portion of the sub disk, and the sub disk is provided on the main disk. After being superimposed on the surface, the center of the sub disk is detachably attached to the center of the main disk by the second bolt, and the peripheral edge of the sub disk is also attached to the peripheral edge of the main disk by the third bolt / nut. The space enclosed by the three planes of the intermediate band portion of the two disks and the wheel rotation axis facing each other is framed as a three-dimensional truss with a triangular cross section with the rotation axis as the base. Is what you do.

[0009]

According to the above construction of the present invention, the sub disk is detachably attached to the surface of the wheel main disk in a superposed state by the second bolt at the center and the third bolt and nut at the peripheral edge. In the assembled state, the space surrounded by the three planes of the intermediate band portion of the two disks facing each other and the wheel rotation axis is a three-dimensional truss with a triangular cross section whose bottom is the rotation axis. As a result, it can be finished as a remarkably high-strength wheel disk, and it has a rich solid feeling and three-dimensional feeling as a modeling pattern on the ventilation, especially for use in mounting on higher-grade automobiles, You can get the optimal wheel.

In addition, since the molding patterns for ventilation provided to the intermediate band portions of both disks are set so as to be different from each other, it is necessary to attach / detach / replace sub disks to be combined with the main disk. By

2) is a pair of a wheel main disk and a sub disk having substantially the same diameter as each other, and the sub disk (D2) is assembled and integrated on the surface of the main disk (D1) in a superposed state. In addition to forming a so-called double-structured wheel disk (D), the tire supporting rim (R) can be stably
It is designed to hold firmly.

First, as for the main disk (D1), it is preferably integrally cast from a light alloy such as an aluminum alloy, and its peripheral edge is formed as a joining ring (11) to be bent backward from this. Out of the above-mentioned tire supporting rims (R), the rear rims (R1) are integrally provided, and the joint ring (11) has a plurality of screw holes (12) for fastening to the sub disk (D2). It is open in the distribution state. (13) is a comparatively thick mounting base also forming the center of the main disk (D1), and is connected to the hub (1) of the axle via the adapter ring (A).
4), it is attached and fixed so that it can rotate integrally.

That is, the first bolt relief hole (15) formed in the adapter ring (A) is fitted into the first bolt (16) integrally planted from the hub (14) of the axle. By screwing a nut (17) to one bolt (16), the adapter ring (A) is firstly attached to the hub (14) of the axle and integrated. Then, the mounting base (13) of the main disk (D1) is closely fitted to the adapter ring (A).
By screwing the second bolt (18) from the mounting base (13) into the adapter ring (A), the main disk (D) is secondarily inserted into the adapter ring (A).
1) is attached and fixed.

(19) is a first bolt receiving screw hole opened in the adapter ring (A). Needless to say, the phase of the first bolt receiving hole (15) is changed. (20) is the second of the adapter ring (A)
A second bolt relief hole (18a) opened in the mounting base (13) of the main disk (D1) so as to coincide with the bolt receiving screw hole (19), and a diameter (18a) of the second bolt (18) is large. It shows a perfect head.

(S1) is a ventilation pattern provided in the intermediate zone between the joining ring (11) and the mounting base (13) in the main disk (D1). Although it is embodied as a so-called mesh type which crosses, it is needless to say that the mesh type is not limited to the mesh type, and a pseudo wire spoke type and a mesh type as shown in FIG. 3 can be widely used.

In any case, the intermediate zone on the main disk (D1) on which the constant shaping pattern (S1) is applied is entirely perpendicular to the wheel rotation axis (XX) or more than this. It extends in a plane of relation that intersects a slightly smaller acute angle (β).

On the other hand, as for the sub disk (D2), it is desirably made by forging from a light alloy or other plastic working, and its central portion corresponds to the mounting base (13) of the main disk (D1). As the decorative base (22) to be used, the second bolt (18) is also used as it is, and is removably fastened and fixed to the mounting base (13). (23) is a relief hole for the second bolt opened in the decorative base (22), (24)
Is a cover ring disposed on the periphery of the sub disk (D2) so as to correspond to the joining ring (11) of the main disk (D1).
A relief hole (25) for the third bolt corresponding to (2) is opened.

The intermediate band occupying the center of the sub disk (D2) between the decorative base (22) at the center and the covering (24) at the periphery is also provided as follows:
A ventilation molding pattern (S2) different from the molding pattern (S1) of the main disk (D1) is applied. That is, the pattern patterns such as the entire mesh type and the pseudo wire spoke type by the rib group are mutually changed.

Further, the intermediate band portion of the sub-disk (D2) extends in a plane of relation which intersects the wheel rotation axis (XX) at an acute angle (γ) which is non-perpendicular to the main disk. A space surrounded by three planes of the intermediate band portion of (D1) and the intermediate band portions of the discs (D1) and (D2) facing each other and the wheel rotation axis (XX) is defined as a wheel rotation axis. (XX)
The truss is divided into a three-dimensional truss with a triangular cross section. Each vertex position of the triangular unit shape is indicated by a reference symbol (a).
(B) and (c) are described, and as suggested from this, the acute angle (γ) on the sub disk (D2) side is smaller than the acute angle (β) on another main disk (D1) side. Is preferred.

By mounting on such a space truss, the strength of the entire wheel disc is increased, and at the same time, the combination of the shaping patterns (S1) and (S2) differently changed in the intermediate band portion of both discs (D1) and (D2). Thus, the solid feeling and three-dimensional effect of the modeling can be effectively exhibited, and the aesthetically pleasing modeling beauty in harmony with the vehicle body can be easily obtained.

Further, (R2) is the rear rim (R
1) is a front rim which, together with 1), forms the overall tire support rim (R), as is evident from FIG.
Between the joint ring (11) and the cover ring (24) of the sub disk (D2), and firmly fastened by a third bolt (26) and a nut (27) penetrating the three. It is integrated. (28) is a mounting ring projecting inward from the front rim (R2), (2)
Reference numeral 9) denotes a third bolt relief hole opened in the mounting ring (28), and reference numeral (30) denotes a seal ring inserted in a joint surface between the rear rim (R1) and the front rim (R2).

As described above, the front rim (R2) is formed separately from the rear rim (R1), and the front rim (R2) is sandwiched between the peripheral edges of the main disk (D1) and the sub disk (D2). Bolt (26) and nut (2)
If it is detachably fastened through 7), there is an effect that, when the offset amount of the vehicle wheel is changed, it can be dealt with only by replacing the front rim (R2) as shown by the chain line in FIG.

[0023] However, also serves as a third bolt (26) for fastening the both disk (D1) (D2), as far as the tire supporting rim (R) is also capable of maintaining the fixing state, the part content modification of FIG. 4 as shown, Do is permissible to form tracks its front rim (R2) continuously integrally with the sub-disc (D2)
No.

Further, the main disk (D1) and the sub disk (D2) have, in addition to the above-mentioned differences in the molding patterns (S1) and (S2), one of their own materials made of steel and the other made of light alloy. It is also possible to change the manufacturing method or the like differently, or to change the processing method or the like applied to the surfaces of the two intermediate zones. That is, for example, the main disk (D
1) and the sub disk (D2), one surface is exposed as a casting surface cloth, and the other surface is subjected to a non-casting surface treatment such as cutting, polishing, painting, plating, etc., to obtain the gloss or the like. It can also be said that it is effective to change the impression such as color.

[0025]

As described above, in the present invention, the adapter ring (A) is attached to the hub (14) of the axle by the first bolts / nuts (16) and (17), and the wheel ring is attached to the adapter ring (A). The center part of the disk (D1) is attached by the second bolt (18), and the periphery of the main disk (D1) is also assembled with the tire supporting rim (R) by the third bolt nut (26) (27). In addition, in an assembling type vehicle wheel, a fixed ventilation pattern (S1) is provided in an intermediate band portion between a center portion and a peripheral portion of the main disk (D1).

A sub disk (D2) separate from the main disk (D1) is prepared, and the sub disk (D2) is prepared.
Of the main disk (D1), the sub-disk (D2) is superimposed on the surface of the main disk (D1). After the alignment, the center of the sub disk (D2) is moved to the center of the main disk (D1) by the second bolt (18), and the periphery of the sub disk (D2) is also moved to the periphery of the main disk (D1). By the third bolts and nuts (26) and (27), they are removably fastened and fixed together, and the intermediate band portions of the opposed disks (D1) and (D2) and the wheel rotation axis (XX) are fixed. Since the space surrounded by the three planes is framed as a three-dimensional truss having a triangular cross-section with the rotation axis (XX) as the bottom surface, the double truss is useful for improving the prior art described at the beginning. There is an effect that can provide an automotive wheel of Isku structure.

That is, the sub-disk (D2) is previously independent of the main disk (D1), and faces each other when the sub-disk (D2) is superimposed and assembled on the surface of the main disk (D1). As indicated by the reference symbols (a), (b) and (c), the space surrounded by the three planes of the intermediate band portion of both disks (D1) and (D2) and the wheel rotation axis (XX) is shown in FIG. Since it is constructed as a three-dimensional unit truss with a triangular cross section with the wheel rotation axis (XX) as the bottom surface, unlike the conventional wheel cap and center cap, the strength of the wheel disk itself is of course Thus, it is possible to obtain an automobile wheel excellent in the supporting strength of the tire supporting rim (R).

In order to achieve such an effect, the sub disk (D2) has substantially the same diameter as the main disk (D1), and both of the disks (D1) and (D2) have the same diameter.
In the center portion, the second bolt (18) is also used, and in the peripheral portion, the third bolt and nuts (26), (27) are also used. -The nuts (26) and (27) effectively work together with the tire supporting rim (R) at once, which contributes to the strength up of the wheel itself, which is different from accessory parts such as the above caps. That is to say.

Moreover, the double disk structure of the present invention comprises a main disk (D1) and a sub disk (D2).
Since the truss is constructed as a three-dimensional truss having a triangular unit in cross section as described above, it is possible to obtain an aerial modeling beauty that is rich in a three-dimensional feeling and a solid feeling. In particular, since the ventilation band patterns (S1) and (S2) having different patterns from each other are provided in the intermediate band portions of the two disks (D1) and (D2), the molding beauty is combined with the main disk (D1). To attach / detach / replace the sub disk (D2)
Various changes can be made, and there is also an effect that a desired molding beauty that is compatible with the vehicle body can be easily obtained. Such an effect can be further increased by adding the configuration according to claim 2.

Further, the sub-disk (D2) is separate and independent from the main disk (D1) and is assembled and integrated as a literal double structure of each other.
In addition to its integral casting, it can also be manufactured by forging or other plastic working, and in that sense it has the effect of finishing a high-strength wheel disk,
It is also beneficial for mass production.

Furthermore, if the configuration of claim 3 is adopted,
By replacing the separate front rim (R2), it is possible to cope with changes in the offset amount, and it can be said that the use of the adapter ring (A) is also helpful.
