Description

[Detailed Description of the Invention] [Object of the Invention] The present invention relates to a vehicle wheel, and it is an object of the invention to provide a three-piece vehicle wheel capable of easily and largely offsetting and stably mounting a tire. It is a thing.

Industrial application field A 3-piece vehicle wheel that enables a large amount of offset.

2. Description of the Related Art Conventionally, various types of vehicle wheels have been proposed, but recently, the distance (that is, offset) between the disk mounting surface and the rim center surface in the disk portion is inset, and the disk mounting surface is Offset vehicles positioned outside the rim center plane are becoming increasingly popular, and it is considered preferable to increase the offset amount from the viewpoint of disposition of a brake mechanism, and various proposals have been made for such purpose. .

That is, the actual application Sho 5 published in the actual development Sho 58-142101.
In the specification and drawings of 7-40194, a divided rim body and a disk body are used, and these are fastened by tightening means, and a hump portion, a bead seat portion and a flange portion are formed on each rim body. It has been announced to do so.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In any of the conventional proposals for such a purpose, however, the disk portion has dimensions and structure according to the JIS standard for engaging the end portion of the tire at the rim portion. The bead seat part and the hump part are provided in the well part located in the central part in the width direction, and the well part located in the central part from the hump part is provided with the disk part. There is a limit to the amount of offset that can be obtained, and it is not possible to obtain the amount of offset due to a large inset. For this reason, the present inventor has made a proposal such as Japanese Utility Model Application No. 59-17446 (Japanese Utility Model Application Laid-Open No. 60-130101), that is, a mounting seat for mounting the disc portion on the axial center side of the bead seat portion in the rim portion. It was proposed that a large inset offset amount be obtained by this method, but it is natural that the offset amount is limited in the rim area even if this is done, and the disc portion mounting The processing man-hours or the structure for projecting the seat in the axial direction becomes complicated, and the cost increases accordingly.

The same applies to the above-mentioned Japanese Utility Model Application No. 57-40194 by Japanese Utility Model Application Laid-Open No. 58-142101.
Rather, in this product, the hump part and the flange part are basically installed on both sides of the disk, so the offset amount is almost the same as the conventional one, and a large offset amount should be obtained. It is not possible to do so as shown in the figure.

Further, it is conceivable to adopt welded joints or weld deposits as one of the methods for avoiding such disadvantages, but the adoption of such welding is unavoidable to cause high residual stress along with thermal change. However, the strength is deteriorated and the cost is inevitably increased.

[Means for Solving the Problem] Means for Solving the Problems A rim portion body, a disc portion body and an interposing member are formed, and an inner hump portion, a bead seat portion and a flange portion are formed on the rim portion body together with a well portion. The interposing member is formed as a T-shaped member having a cross section having a base interposed between the mounting seat of the rim body and the tightening seat of the disc body formed in the middle, and the base is fastened by the tightening means. An outer hump portion facing the inner hump portion or the flange portion of the rim body, a bead seat portion and a flange portion, the outer hump portion of which is formed on one of the base portions. The flange portion is formed on the other side of the base portion, and the outer hump portion has a distal end formed with a locking portion that is in contact with the mounting seat of the rim body and the well portion. Between Vehicle wheels, characterized in that filled with Lumpur material.

Action The interposition member is formed as a T-shaped cross-section member in which a base portion interposed between the mounting seat portion of the rim portion body and the tightening seat of the disc portion body is formed in the middle, thereby mounting the interposition member. The state is balanced, and in particular, a locking portion that is joined to the outer surface of the mounting portion side of the rim portion body is formed on the back surface of the inner hump portion of the interposition portion body, and the locking portion is formed by the tightening seat of the disc portion body. By pressing the base part against and tightening it, the assembled state of this interposition part becomes extremely stable,
Stabilize tire equipment with large offset.

An outer hump portion, an outer flange portion, a bead seat portion and a flange portion facing the inner hump portion or the flange portion of the rim portion body are provided on the outer end portion of the interposition portion body formed integrally with the base portion. Since the hump portion is formed on one side of the base portion and the flange portion is formed on the other side of the base portion, the outer hump portion can be positioned at least outside the body surface of the disc portion, and the offset amount by the inset can be reduced. Make it possible to be significantly larger.

By applying a sealing material such as silicone rubber to the V-shaped gap formed between the tip of the locking portion and the rim member, the sealing material is pressed into the V-shaped gap by the air pressure filled in the tire to form an effective seal. Effectively forms a tubeless wheel. Further, since the engaging portion is located inside the outer bead seat portion and the hump portion, air leakage is prevented by preventing seal damage when tires are replaced.

By using the three-piece system including the rim body, the disc body, and the interposition body, the wheel capable of sufficiently taking the offset as described above has a wide variety of products. That is, the outer rim portion (outer hump portion to outer flange portion) can be appropriately formed as a balanced structure in the integrally formed interposition member, and can be stably assembled with the inner rim member having the well portion, and the flange for the base portion can be formed. By adopting an interposing member in which the distance between the outer portion and the outer hump portion is appropriately changed, it is possible to quickly respond to changes in tire width (well portion width) and the like.
