Abstract

The outside surface 14a of a window part forming portion 14 in the disc radial direction is made planar. Thus, when an in-plane compressive force is applied to the window part forming part 14 by being transferred to a disc 10 via a rim 110 from a tire, a thrust force is applied to the window part forming part 14, thereby making the window part forming part 14 less prone to deformation than ever. Consequently, the rigidity of the disc 10 becomes higher than ever.

Has a side curve,
The window portion forming portion extends inward in the disc axial direction from the outer peripheral side curved portion of the disc intermediate portion, and the disk radial direction outer surface of the window portion forming portion is a plane.
Vehicle wheel.
(2) The vehicle wheel according to (1), wherein the window portion forming portion extends in a direction parallel to the disk axial direction.
(3) The vehicle wheel according to (1), wherein the window portion forming portion extends in a direction inclined from a direction parallel to the disk axial direction.
　上記（１）の車両用ホイールによれば、窓部形成部のディスク半径方向外側面が平面とされている。そのため、タイヤからリムを介してディスクに伝わってきて窓部形成部に面内圧縮力がかかった際、窓部形成部には突っ張り力がかかることになり、従来に比べて窓部形成部は変形しにくくなる。よって、ディスク剛性が従来に比べて高まる。 According to the vehicle wheel of (1) above, the outer surface in the disk radial direction of the window forming portion is a flat surface. Therefore, when the in-plane compression force is applied to the window forming portion from the tire through the rim to the disk, the window forming portion is subjected to a tensile force. It becomes difficult to deform. Therefore, the disc rigidity is increased as compared with the conventional case.
上記（２）の車両用ホイールによれば、窓部形成部がディスク軸方向と平行な方向に延びているため、平板状のディスク素材をプレス機を用いて絞り成形する際に、複数の窓部形成部を絞り加工する方向とプレス機の加圧スライド方向とを一致させることができる。そのため、窓部形成部がディスク軸方向と平行な方向に延びていない場合に比べて、窓部形成部を容易に加工できる。 According to the vehicle wheel of (2) above, since the window portion forming portion extends in a direction parallel to the disk axial direction, a plurality of windows are formed when the flat disk material is drawn using a press. The direction in which the part forming part is drawn can be matched with the pressure slide direction of the press. Therefore, the window portion forming portion can be easily processed as compared with the case where the window portion forming portion does not extend in a direction parallel to the disk axial direction.
上記（３）の車両用ホイールによれば、窓部形成部がディスク軸方向と平行な方向から傾斜する方向に延びているため、窓部形成部がディスク軸方向と平行な方向に延びる場合に比べて、ホイールの内部スペースを大きくすることができる。 According to the vehicle wheel of (3) above, since the window portion forming portion extends in a direction inclined from a direction parallel to the disc axis direction, the window portion forming portion extends in a direction parallel to the disc axis direction. In comparison, the internal space of the wheel can be increased.

　窓部形成部１４は、図１に示すように、ディスクフランジ部１３よりもディスク半径方向内側に位置している。窓部形成部１４は、リム１１０とは接触しておらず、リム１１０との間に窓部（隙間といってもよい）Ｗを形成する。 As shown in FIG. 1, the window portion forming portion 14 is located on the inner side in the disc radial direction than the disc flange portion 13.

In the disk radial direction, the end of the disk intermediate portion 15 on the hub mounting portion 12 side extends from the hub mounting portion 12 outward in the disk radial direction and outward in the disk axial direction. In the disk radial direction, the end of the disk intermediate portion 15 on the disk flange portion 13 side and the end on the window forming portion 14 side extend outward in the disk radial direction and inward in the disk axial direction.
ディスク中間部１５は、ディスク中間部１５のディスク半径方向中間部に、ディスク周方向に連続しディスク軸方向に突出した環状突起部１５ｂを有していてもよい。また、ディスク中間部１５には、ディスク中間部１５のディスク半径方向中間部に、ディスク周方向に等間隔に複数個の飾り穴１５ｃが設けられていてもよい。環状突起部１５ｂと飾り穴１５ｃがともに設けられる場合、飾り穴１５ｃは、環状突起部１５ｂよりディスク半径方向外側に設けられている。 The disc intermediate portion 15 may have an annular protrusion 15 b that is continuous in the disc circumferential direction and protrudes in the disc axial direction at the disc radial direction intermediate portion of the disc intermediate portion 15.

　ここで、本発明全実施例にわたって共通する作用、効果を説明する。
本発明実施例では、窓部形成部１４のディスク半径方向外側面１４ａが平面とされている。そのため、タイヤからリム１１０を介してディスク１０に伝わってきて窓部形成部１４に面内圧縮力がかかった際、窓部形成部１４には突っ張り力がかかることになり、従来に比べて窓部形成部１４は変形しにくくなる。よって、ディスク１０の剛性が従来に比べて高まる。窓部形成部１４とディスクフランジ部１３とが湾曲部Ｒのみを介して連なる場合、ディスク１０の剛性はさらに高まる。
その結果、ディスク１０とリム１１０との結合力を向上できる、ディスク１０とリム１１０との溶接部の捩れ変形の発生を抑制できる、等の作用効果を得ることができる。 Here, operations and effects common to all the embodiments of the present invention will be described.
In the embodiment of the present invention, the disk radial direction outer side surface 14a of the window portion forming portion 14 is a flat surface. Therefore, when the in-plane compression force is applied to the window portion forming portion 14 from the tire via the rim 110 and applied to the disk portion forming portion 14, a tensile force is applied to the window portion forming portion 14. The part formation part 14 becomes difficult to deform | transform. Therefore, the rigidity of the disk 10 is increased compared to the conventional case. When the window part forming part 14 and the disk flange part 13 are connected via the curved part R only, the rigidity of the disk 10 is further increased.
As a result, it is possible to obtain operational effects such as the ability to improve the coupling force between the disk 10 and the rim 110 and the suppression of the occurrence of torsional deformation at the welded portion between the disk 10 and the rim 110.
窓部形成部１４がディスク軸方向と平行な方向に延びている場合、複数の窓部形成部１４を絞り加工する方向とプレス機（図示略）の加圧スライド方向とを一致させることができる。そのため、窓部形成部１４がディスク軸方向と平行な方向に延びていない場合に比べて、平板状のディスク素材（図示略）をプレス機を用いて絞り成形する際に、窓部形成部１４を容易に加工できる。また、窓部形成部１４を当該部位を成形するパンチとダイによりしごき加工を行うことができ、しごき加工を行わない場合よりもディスク側面視における窓部形成部１４のディスク軸方向距離Ｌを大きくしてもよい。 When the window portion forming portion 14 extends in a direction parallel to the disk axial direction, the drawing direction of the plurality of window portion forming portions 14 can be matched with the pressure slide direction of a press (not shown). . For this reason, when forming a flat disk material (not shown) using a press, the window forming part 14 is compared with a case where the window forming part 14 does not extend in a direction parallel to the disk axial direction. Can be easily processed. Further, the window forming portion 14 can be ironed by a punch and a die for forming the part, and the disc axial direction distance L of the window forming portion 14 in the side view of the disc is larger than when the ironing is not performed. May be.
窓部形成部１４がディスク軸方向と平行な方向ＡＸに延びている場合、窓部形成部１４のディスク軸方向内側端縁１４ｂが、窓部形成部がディスク半径方向外側かつディスク軸方向内側に傾斜する場合（図４の２点鎖線）におけるディスク軸方向端縁Ａよりもディスク軸方向内側（図４における下側）にある。そのため、ディスク側面視における窓部形成部１４のディスク軸方向距離Ｌが、窓部形成部がディスク半径方向外側かつディスク軸方向内側に傾斜する場合における窓部形成部のディスク軸方向距離Ｌ１よりも長く（大きく）なる。よって、窓部形成部１４に面内圧縮力がかかった際における窓部形成部１４の変形抑制を効果的に図ることができる。 When the window portion forming portion 14 extends in the direction AX parallel to the disc axial direction, the inner edge 14b in the disc axial direction of the window portion forming portion 14 is located on the outer side in the disc radial direction and the inner side in the disc axial direction. When tilted (two-dot chain line in FIG. 4), it is on the inner side in the disk axis direction (lower side in FIG. 4) than the edge A in the disk axis direction. Therefore, the disc axial direction distance L of the window forming portion 14 in the disc side view is larger than the disc axial direction distance L1 of the window forming portion when the window forming portion is inclined outward in the disc radial direction and inward in the disc axial direction. Longer (larger). Therefore, it is possible to effectively suppress the deformation of the window forming portion 14 when an in-plane compressive force is applied to the window forming portion 14.
窓部形成部１４がディスク軸方向と平行な方向ＡＸから傾斜する方向に延びている場合、窓部形成部１４がディスク軸方向と平行な方向に延びる場合に比べて、ホイール１００の内部スペースを大きくすることができる。 When the window forming part 14 extends in a direction inclined from the direction AX parallel to the disk axial direction, the internal space of the wheel 100 is reduced as compared with the case where the window forming part 14 extends in a direction parallel to the disk axial direction. Can be bigger.
