Description

[Detailed Description of the Invention] ``Purpose of the Invention'' The present invention relates to a vehicle wheel, and aims to provide a vehicle wheel that can easily and largely offset the wheel and form a stable assembled state. be.

Industrial Applications Vehicle wheels with a large amount of offset.

BACKGROUND TECHNOLOGY Various types of vehicle wheels have been proposed in the past, but offset vehicles, in which the hub mounting surface of the disc portion is located outside the rim center line, are becoming increasingly popular in recent years.
It is considered preferable to increase the amount of offset, and various proposals have been made for this purpose.

Problems to be Solved by the Invention However, in any of the conventionally proposed devices for this purpose, the disc part is separated from the bead seat part and hump part for securing the end of the tire at the rim part. The disc part is provided in the well part located in the center of the rim part in the width direction, and there is a limit to the amount of offset that can be obtained by providing the disc part in the well part located in the center part than the hump part. In some cases, there is even a tendency for a negative offset to occur, making it impossible to obtain a large amount of offset. For this reason, the present invention proposes a mounting seat for mounting the disk part on the axis side of the bead seat part in the rim part. Although it has been proposed to provide a ring in order to obtain a large amount of offset, it is natural that the amount of offset will be limited within the body area of the rim.

``Structure of the invention'' Means for solving the problem The rim body is composed of a rim body, a disk body, and an intervening member, and the rim body is formed with an outer hump part, a beat seat part, and a flange part, and the above-mentioned intervening The base of the mounting member is interposed between the mounting seat of the rim body and the tightening seat on the circumferential side of the disk body, and is fastened by a tightening means, and a supporting portion integrally formed with the base; It consists of a folded part, and the folded part forms a bead seat part and a hump part together with an inner flange part, and an engaging end part connected to the rim part body is formed at the tip thereof, and the engaging end part and the above-mentioned A vehicle wheel characterized in that a sealing material is applied and sealed between the rim body and the rim body.

Function The disc body, the rim body, and the intervening member are integrally connected by the tightening means, so that the rim body holds the outer part, and the interposed part body holds the hump part, bead seat part, and flange part of the inner part. Each is formed at a predetermined position.

The engaging end portion at the tip of the folded portion is joined to the rim body to form stable assembly strength.

Embodiment A specific embodiment of the present invention will be described with reference to the attached drawings.The present invention is designed to fasten and assemble a rim body 1 and a disk body 2 by means of a tightening means 4. An intervening member 3 is used between the two parts 1 and 2,
The rim body 1 has an outer hump part 13, a bead seat part 12 and a flange part 11 on one side of the well part 14.
It is attached to the disk body 2 at a mounting seat 15 formed on the other side. The disc body 2 is provided with an engaging portion 21 and a tightening seat 22 on its circumferential side, so that it can be tightened by the tightening means 4. The intervening member 3 consists of a base part 3a interposed between the mounting seat part 15 and the tightening seat 22 as described above, a support part 3b integrally formed on the outside of the base part 3a, and a folded part 3c. An engaging end portion 34 that forms an inner flange portion 31, a bead seat portion 32, and a hump portion 33, and engages with the rim body 1 at the tip of such a folded portion 3c.
As shown in the figure, the bent portion 3d, which forms the boundary between the supporting portion 3b and the folded portion 3c, is formed with a sufficiently thick wall by the bending process.

The disk body 2 can be easily obtained with an appropriate design by casting, and the rim body 1 and the intervening member 3 can be easily obtained by processing aluminum extrusion or plate material. When tightening the member 1 with the tightening means 4, the interposed member 3
The base portion 3a is inserted between the members 1 and 2 and stably fastened, and the locking portion 35
It is fixed stably and firmly.

By appropriately applying a sealing material between the above-mentioned engaging end portion 34 and the rim body 1, air leakage from this portion can be prevented and a tubeless type wheel can be obtained. As the sealing material, a member made of rubber or soft synthetic resin may be inserted and assembled, but in some cases, an irregularly shaped sealing material 6 made of silicone rubber or the like may be applied.
That is, as shown in the figure, by adopting a suitable circular arc at the tip of the engaging end portion 34 and joining it to the outer surface of the rim body 1, a V-shaped valley is formed in the portion.
A stable seal can be formed by applying the sealing material 6, which is a semi-fluid, irregularly shaped sealing material, to such a valley and solidifying it. The internal pressure caused by the air filled in the tire acts to push the sealing material 6 into the above-mentioned V-shaped valley, and since this acting force is proportional to the internal pressure, leakage will not occur even with considerably high air pressure. do not have.

"Effect of the invention" According to the invention as explained above, only the bead seat part 12 and the flange part 11 on the outside are formed as the rim body 1, and those on the inside are formed on the intervening member 3. Therefore, the whole of the rim body 1 can be used for offset, and the intervening member 3 has a folded part 3c overlapping inside the base part 3a and the support part 3b. By forming the flange portion 31, bead seat portion 32, and hump portion 33 on the folded portion 3c, a large offset such that the tire is located substantially outside the disc body can be achieved; In such a folded part 3c, it is possible to sufficiently increase the strength of the part fixed to the disk body 2, and since the tip of the folded part 3c is joined to the surface of the rim body 1 as the engaging part 34. This device has the effect of being able to obtain sufficient support strength when the tire that is fastened and set receives a load, and is a highly effective device in practical terms.
