Description

本発明は、リムとディスクとの２ピースを溶接で結合した「２ピースホイール」で、意匠面の全面あるいはほぼ全面がディスク面のみから構成されるホイール、いわゆる「フルデザインホイール」に関する。 The present invention relates to a so-called “full design wheel”, which is a “two-piece wheel” in which two pieces of a rim and a disc are joined by welding, and the entire design surface or almost the entire surface is composed of only the disc surface.

特開平１１−１５１９０１号公報、特開平１１−４２９０１号公報は、２ピースフルデザインホイールを開示している。
図１１、図１２に示すように、従来の２ピースフルデザインホイール１は、リム２のビードシート部４の軸方向先端部を、フランジ部５を形成したディスク３の、フランジカール部６より内周側部分の背面に、溶接したものから構成されていた。そこでは、軸方向外側のフランジ部５はディスク３に形成されていた。 Japanese Patent Application Laid-Open Nos. 11-151901 and 11-42901 disclose a two-piece full design wheel.
As shown in FIGS. 11 and 12, the conventional two-piece full design wheel 1 is configured such that the front end portion in the axial direction of the bead seat portion 4 of the rim 2 has an inner periphery from the flange curl portion 6 of the disk 3 in which the flange portion 5 is formed. It consisted of what was welded to the back of the side part. Here, the axially outer flange portion 5 was formed on the disk 3.

そのため、図１１に示すように、カール部６の存在によって、飾り窓８を外周側に寄せることができず、意匠面が外周側から制限されて、意匠を大きくできないという問題があった。また、ホイールを軸方向外側から見た時にフランジ５の凹状のカール部６と先端面７の両方が見え、見栄えが悪いという問題があった（凹状のカールは見栄えが悪い）。
特開平１１−１５１９０１号公報特開平１１−４２９０１号公報 Therefore, as shown in FIG. 11, the presence of the curled portion 6 has a problem that the decorative window 8 cannot be moved to the outer peripheral side, the design surface is restricted from the outer peripheral side, and the design cannot be enlarged. Further, when the wheel is viewed from the outside in the axial direction, both the concave curled portion 6 and the tip surface 7 of the flange 5 are visible, and there is a problem that the appearance is bad (the concave curl is not good).

（２）前記リムを軸方向にリバース使いした（１）記載の２ピースフルデザインホイール。
The present invention for achieving the above object is as follows.
(1) A two-piece full-design wheel in which the rim and disk are welded at the tip of the rim flange,
The flange of the rim has a rising portion that rises in the wheel radial direction from the tip end in the axial direction of the bead seat portion, and a curled portion that bends outward in the axial direction from the outer peripheral portion of the rising portion. A two- piece full design wheel which is not formed and welds the rim to the radially outer end of the disc at the axially outer end of the curl portion of the flange of the rim.
2 2-piece full design wheel the rim was used reverse in the axial direction (1) Symbol placement.

上記（１）の２ピースフルデザインホイールによれば、フランジはディスクには形成されずにリムに形成されており、リムのフランジの先端でリムとディスクを溶接したので、意匠面がフランジのカール部に制限されず、意匠面をディスク外周端まで広げることができ、意匠を大きくすることができる。
上記（２）の２ピースフルデザインホイールによれば、リムを軸方向にリバース使いしてドロップ部からビードシート部への立ち上がり傾斜がゆるやかな方のビードシート部に接続するリムフランジにディスクを溶接したので、ディスクの飾り窓を通してリム内面を見たときに、リム内面の見え方に奥行き感がでて、高意匠性が保たれる。 According to the two-piece full design wheel of (1 ) above, the flange is not formed on the disk but formed on the rim, and the rim and disk are welded at the tip of the flange of the rim.

Therefore, when the inner surface of the rim is viewed through the decorative window of the disk, a sense of depth appears in the appearance of the inner surface of the rim, and high design properties are maintained.

本発明の２ピースフルデザインホイールを、図１〜図１０を参照して説明する。
本発明の２ピースフルデザインホイール１０は、図１、図２に示すように、リム１１とディスク１２との２ピースを溶接部１３で溶接にて結合した２ピースホイールであり、かつ、意匠面１４（ここで、「意匠面」とは、ホイールが車両に組付けられた時に、車両の左右方向外側から見える面で、意匠を構成することができる面を言い、従来のフランジカール部は含まない）の全面あるいはほぼ全面（「ほぼ全面」としたのは、図９のように、リム端面１５のみが意匠面にあらわれる場合は本発明に含んでもよいためである）がディスク面のみから構成されるホイール、いわゆる「フルデザインホイール」（「フルフェースホイール」とも言う）である。
フルデザインホイールでは、通常は、リム１１とディスク１２との溶接部１３は意匠面１４にあらわれない。ただし、リム端面１５のみが意匠面にあらわれる場合（図９）は、溶接部１３もリム端面１５の内周に沿ってあらわれるが、溶接部１３がディスクの外周端のみにあるのであれば、意匠をほとんど制限しないので、本発明は図９の場合も含む。
リム１１、ディスク１２は、それぞれ、スチール製、またはアルミ合金（展延材）製、またはチタン合金（展延材）製である。溶接部１３は、全周連続溶接、または周方向に間欠的に形成された連続溶接である。 The two-piece full design wheel of the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the two-piece full design wheel 10 of the present invention is a two-piece wheel in which two pieces of a rim 11 and a disk 12 are joined by welding at a welded portion 13, and has a design surface 14. (Here, “design surface” refers to a surface that is visible from the outside in the left-right direction of the vehicle when the wheel is assembled to the vehicle and that can constitute the design, and does not include a conventional flange curl portion. ) Or substantially the entire surface (“substantially the entire surface” is because only the rim end surface 15 may be included in the design surface as shown in FIG. 9 because it may be included in the present invention). The so-called “full design wheel” (also referred to as “full face wheel”).
In the full design wheel, the welded portion 13 between the rim 11 and the disk 12 usually does not appear on the design surface 14. However, when only the rim end surface 15 appears on the design surface (FIG. 9), the welded portion 13 also appears along the inner periphery of the rim end surface 15, but if the welded portion 13 is only on the outer peripheral end of the disc, the design Therefore, the present invention includes the case of FIG.
The rim 11 and the disk 12 are each made of steel, aluminum alloy (spreading material), or titanium alloy (spreading material). The welded portion 13 is continuous welding all around or continuously formed in the circumferential direction.

本発明の２ピースフルデザインホイール１０は、リム１１のフランジの先端部１６（フランジの先端部１６は、リム端面１５と、リム端面１５に続く部分とを含む）でリム１１とディスク１２とを溶接した２ピースフルデザインホイールである。
リム１１は、軸方向外側（ホイールが車両に組付けられた時に、車両の左右方向外側から見える側）から軸方向内側に、順に、軸方向外側フランジ１７、軸方向外側ビードシート部１８、軸方向外側サイドウォール部１９、ドロップ部２０を有し、さらに、軸方向内側サイドウォール部２１（軸方向内側サイドウォール部２１は、軸方向外側サイドウォール部１９に比べて、通常、ドロップ部２０からビードシート部への傾斜がゆるやかである）、軸方向内側ビードシート部２２、軸方向内側フランジ２３を有する。
従来の２ピースフルデザインホイールでは、軸方向外側フランジは、ディスクに形成されていたが、本発明では、リム１１に形成されている。ディスク１２は、軸方向外側フランジをもたず、リムフランジのような急激な、軸方向外側に曲がるフランジカール部をもたない。ディスク１２の外周部はホイール軸芯とほぼ直交する方向に延びるか、または折れ曲がってもホイール軸方向内側に曲がる。ディスク１２の外周部は、リムのフランジカール部のようなホイール軸方向外側に曲がる曲がり部をもたないか、またはホイール軸方向外側に曲がってもリムのフランジカール部のよう急激な曲がりとならない。
リム１１の軸方向外側フランジ１７は、軸方向外側ビードシート部１８から半径方向外側に立ち上がる立ち上がり部２４と立ち上がり部２４の外周側部分から軸方向外側に曲がるカール部２５を有する。
そして、リム１１の軸方向外側フランジ１７のカール部２５の軸方向外側端部（フランジの先端部１６）で、リム１１はディスク１２の半径方向外側端部２６に溶接にて結合されている。 The two-piece full design wheel 10 of the present invention welds the rim 11 and the disk 12 to each other at the flange tip 16 (the flange tip 16 includes a rim end surface 15 and a portion following the rim end surface 15). It is a 2 piece full design wheel.
The rim 11 has an axially outer flange 17, an axially outer bead seat portion 18, a shaft in order from the axially outer side (the side seen from the laterally outer side of the vehicle when the wheel is assembled to the vehicle) to the axially inner side. The outer side wall part 19 and the drop part 20 in the direction are further provided. Further, the inner side wall part 21 in the axial direction (the inner side wall part 21 in the axial direction is usually formed from the drop part 20 as compared with the outer side wall part 19 in the axial direction. The bead sheet portion has a gentle inclination), and has an axially inner bead sheet portion 22 and an axially inner flange 23.
In the conventional two-piece full design wheel, the outer flange in the axial direction is formed on the disk, but in the present invention, it is formed on the rim 11. The disk 12 does not have an axial outer flange, and does not have a flange curl portion that bends outward in the axial direction like a rim flange. The outer peripheral portion of the disk 12 extends in a direction substantially orthogonal to the wheel shaft core or bends inward in the wheel axis direction even if it is bent. The outer peripheral portion of the disk 12 does not have a bent portion that bends outward in the wheel axis direction like the flange curl portion of the rim, or does not bend sharply like the flange curl portion of the rim even if bent outward in the wheel axis direction. .
The axially outer flange 17 of the rim 11 has a rising portion 24 that rises radially outward from the axially outer bead seat portion 18 and a curl portion 25 that bends axially outward from the outer peripheral side portion of the rising portion 24.
The rim 11 is joined to the radially outer end 26 of the disk 12 by welding at the axially outer end (flange tip 16) of the curled portion 25 of the rim 11 axially outer flange 17.

The rim tip 16 is abutted in the wheel axial direction. A welding groove extending over a part of the rim thickness is provided on the rim end surface 15 (as a one-side welding groove having a groove only on the rim), and is filled with a weld metal (partial penetration welding), A fillet weld is formed between the back of the disk and the outer surface of the rim. The outer surface of the radially outer end 26 of the disk is radially outward from the outer surface of the rim tip 16 by the length of the fillet weld leg. After welding, the outer surface of the welded portion 13 is left as it is, and no cutting process is performed.

図７の構造では、ディスク１２の外周部はホイール軸芯とほぼ直交する方向に延びており、ディスクの半径方向外側端部２６はホイール軸方向内側に折り曲げられており、この軸方向内側折り曲げ部２８の先端面に、リム先端部１６のリム端面１５をホイール軸方向に突き当てる。リム端面１５とそれが対向するディスクの軸方向内側折り曲げ部２８の先端面に溶接開先を設けておき、そこを溶接金属で埋めてリム１１とディスク１２を溶接（部分溶け込み溶接または完全溶け込み溶接）する。溶接ビードの外面とそれに続くリム部分、ディスク部分の外面は、外周から切削し、ホイール軸芯とほぼ平行に延びるストレート面に仕上げる。 In the structure of FIG. 7, the outer peripheral portion of the disk 12 extends in a direction substantially perpendicular to the wheel shaft core, and the radially outer end 26 of the disk is bent inward in the wheel axial direction. The rim end surface 15 of the rim distal end portion 16 is abutted against the front end surface of the rim 28 in the wheel axis direction. A welding groove is provided at the front end surface of the rim end surface 15 and the axially inner bent portion 28 of the disk facing it, and the rim 11 and the disk 12 are welded by filling with a weld metal (partial penetration welding or full penetration welding). ) The outer surface of the weld bead, the rim portion and the outer surface of the disk portion following the weld bead are cut from the outer periphery and finished to a straight surface extending substantially parallel to the wheel axis.

図８の構造では、リム１１のホイール軸方向外側フランジ１７のカール２５の先端部をカール２５のカール半径より小さい半径でホイール半径方向内側にカールさせて先端カール部２９を形成し、この先端カール部２９の外側側面でディスク１２に当て、先端カール部２９の外側側面とディスク側面とで形成される開先形状を溶接金属で埋めてリム１１とディスク１２を溶接接合する。溶接ビードの外面とそれに続くリム部分、ディスク部分の外面は、外周から切削し、機械加工面に仕上げる。溶接部の「のど厚」を大きくとれるので、溶接部の強度アップをはかることができ、車両重量の大きい車両用ホイールにも用いることができる。 In the structure of FIG. 8, the tip end portion of the curl 25 of the rim 11 in the wheel axial direction outer flange 17 is curled inward in the wheel radial direction with a radius smaller than the curl radius of the curl 25 to form the tip curl portion 29. The rim 11 and the disk 12 are welded to each other by contacting the disk 12 with the outer side surface of the portion 29 and filling the groove shape formed by the outer side surface and the disk side surface of the tip curl portion 29 with weld metal. The outer surface of the weld bead, the subsequent rim portion, and the outer surface of the disk portion are cut from the outer periphery and finished to a machined surface. Since the “throat thickness” of the welded portion can be increased, the strength of the welded portion can be increased, and it can be used for a vehicle wheel having a large vehicle weight.

図９の構造では、ディスク１２の外周部はホイール軸芯とほぼ直交する方向に延びており、ディスク半径方向外側端部２６の外周面にリム先端部１６の内周面を嵌める。リム先端部１６の内周面とそれが嵌まるディスク半径方向外側端部２６の外周面に溶接開先を設けておき、そこを意匠面側から溶接金属で埋めてリム１１とディスク１２を溶接（部分溶け込み溶接または完全溶け込み溶接）する。溶接ビードの表面とそれに続くリム部分、ディスク部分の表面は、ホイール軸方向内側から切削し、意匠面１４と面一な平坦面に仕上げる。この場合は、リム端面１５とその内周側の溶接部１３はホイール軸方向外側から見えるが、リム端面１５とその内周側の溶接部１３は意匠面１４の外周端部のみに位置する。 In the structure of FIG. 9, the outer peripheral portion of the disk 12 extends in a direction substantially perpendicular to the wheel axis, and the inner peripheral surface of the rim tip portion 16 is fitted to the outer peripheral surface of the outer end portion 26 in the disk radial direction. A welding groove is provided on the inner peripheral surface of the rim tip portion 16 and the outer peripheral surface of the disk radial outer end portion 26 into which the rim tip portion 16 is fitted, and the rim 11 and the disc 12 are welded by filling the weld groove from the design surface side. (Partial penetration welding or complete penetration welding).

In this case, the rim end surface 15 and the welded portion 13 on the inner peripheral side thereof are visible from the outer side in the wheel axis direction, but the rim end surface 15 and the welded portion 13 on the inner peripheral side thereof are located only at the outer peripheral end of the design surface 14.

図３〜図９の構造は、傾斜が急な方のサイドウォール部１９に続くビードシート部１８に接続する側のフランジ１７の先端部にディスク１２が溶接される場合の構造であるが、図１０に示すように、リム１１をホイール軸方向に反対にして（すなわち、リム１１をホイール軸方向にリバース（反対）使いして）、傾斜がゆるやかな方のサイドウォール部２１をホイール軸方向外側に向け、この傾斜がゆるやかな方のサイドウォール部２１に続くビードシート部２２に接続する側のフランジ２３の先端部にディスク１２が溶接されてもよい。リム１１をリバース使いした場合のリム先端部１６とディスク１２との溶接構造は、図３〜図９の構造に準じる（図３〜図９の構造と同じ）。図１０の構造も本発明に含む。 The structure of FIGS. 3 to 9 is a structure in which the disk 12 is welded to the tip of the flange 17 on the side connected to the bead sheet portion 18 following the sidewall portion 19 with a steep slope. 10, the rim 11 is reversed in the wheel axial direction (that is, the rim 11 is reversed (opposed) in the wheel axial direction), and the side wall portion 21 having the gentler inclination is disposed outside the wheel axial direction. The disk 12 may be welded to the tip of the flange 23 on the side connected to the bead sheet portion 22 following the side wall portion 21 having a gentler inclination. When the rim 11 is used in reverse, the welded structure between the rim tip 16 and the disk 12 conforms to the structure shown in FIGS. 3 to 9 (the same as the structure shown in FIGS. 3 to 9). The structure of FIG. 10 is also included in the present invention.

つぎに、本発明の２ピースフルデザインホイール１０の作用、効果を説明する。 Next, the operation and effect of the two-piece full design wheel 10 of the present invention will be described.

軸方向外側フランジ１７がディスク１２には形成されずにリム１１に形成されており、リム１１の軸方向外側フランジ１７の先端部でリム１１とディスク１２を溶接したので、意匠面１４がフランジ１７のカール部２５に制限されず、意匠面１４をディスク外周端まで広げることができ、意匠を大きくすることができる。 The axial outer flange 17 is not formed on the disk 12 but is formed on the rim 11, and the rim 11 and the disk 12 are welded at the tip of the axial outer flange 17 of the rim 11, so that the design surface 14 is the flange 17. The design surface 14 can be extended to the outer peripheral edge of the disk without being limited to the curled portion 25, and the design can be enlarged.

また、図１〜図８の構造では、リム端面１５とその内周側の溶接部１３はホイール軸方向外側から見えないので、見栄えがよい。
図９の構造では、リム端面１５とその内周側の溶接部１３がホイール軸方向外側から見えるが、リム端面１５とその内周側の溶接部１３は意匠面１４の外周端部のみに位置するので、意匠をホイール外周側からほとんど制限しない。
図１０の構造では、リム１１をホイール軸方向にリバース使いしたので、ディスク１２の飾り窓３０からリム１１の内面を見た時に、リム内面の見え方に奥行き感がでて、高意匠性が保たれる。 Moreover, in the structure of FIGS. 1-8, since the rim end surface 15 and the welding part 13 of the inner peripheral side are not visible from the wheel-axis direction outer side, it looks good.
In the structure of FIG. 9, the rim end surface 15 and the inner peripheral side welded portion 13 are visible from the outer side in the wheel axis direction, but the rim end surface 15 and the inner peripheral side welded portion 13 are located only at the outer peripheral end portion of the design surface 14. Therefore, the design is hardly restricted from the wheel outer peripheral side.
In the structure of FIG. 10, since the rim 11 is reversely used in the wheel axis direction, when the inner surface of the rim 11 is viewed from the decorative window 30 of the disk 12, the rim inner surface is seen with a sense of depth and high design characteristics are maintained. Be drunk.
