Description

本発明は、高い操縦安定性を確保しつつ車両に伝達される振動を抑制し、乗り心地の向上、車内騒音の低減等を実現できる車両用ホイールを高い生産性で得ることができるとともに、溶接欠陥などによる故障が低減し、環境的に優れる車両用ホイールに関する。   The present invention suppresses vibration transmitted to the vehicle while ensuring high steering stability, and can obtain a vehicle wheel capable of improving ride comfort and reducing in-vehicle noise with high productivity and welding. The present invention relates to a vehicle wheel in which failures due to defects and the like are reduced and environmentally superior.

近年、自動車、特に、高級車とされる自動車においては、操縦安定性と車内空間の快適さとが共に求められている。このため、いわゆる足回りと呼ばれるタイヤ、車両用ホイール、サスペンション等においては、例えば、サスペンションのアクティブ制御技術、防振ゴムやタイヤの構造の改良技術等が開発されてきている。   2. Description of the Related Art In recent years, automobiles, particularly automobiles regarded as luxury cars, are required to have both handling stability and comfort in the interior of the vehicle. For this reason, in tires, vehicle wheels, suspensions, and so on, which are so-called undercarriages, for example, active control techniques for suspensions, anti-vibration rubbers, and tire structure improvement techniques have been developed.

車両用ホイールに関しても種々の改良がなされており、例えば、車内騒音に対して、その大きな要因であるタイヤ空洞共鳴音を抑えるべく、副気室をリムホイール内に設け、この副気室とタイヤ内部主気室と連通させる連通孔の寸法を調整することによりヘルムホルツ共鳴吸音器として作用させる車両用ホイール等が開示されている(例えば、特許文献1参照)。   Various improvements have also been made with respect to vehicle wheels. For example, in order to suppress tire cavity resonance noise, which is a major factor with respect to vehicle interior noise, a secondary air chamber is provided in the rim wheel. There has been disclosed a vehicle wheel or the like that acts as a Helmholtz resonance sound absorber by adjusting the size of a communication hole that communicates with an internal main air chamber (see, for example, Patent Document 1).

例えば、特許文献1に示すリムホイールは、リムとリムの径方向外側に配置される複数の蓋部材との間に形成され、周方向に間隔をあけて設けられた複数の隔壁により分割された複数の副気室と、リムまたは蓋部材の少なくとも一方に設けられ、底部位置がビードシートよりも径方向内側に位置する凹状のウエル部と、タイヤ主副気室と副気室と連通させる連通部とを備えたものであり、副気室と連通部とでヘルムホルツ共鳴吸音器を構成したものである。
特開2002−79802号公報
For example, the rim wheel shown in Patent Literature 1 is formed between a rim and a plurality of lid members arranged on the outer side in the radial direction of the rim, and is divided by a plurality of partition walls provided at intervals in the circumferential direction. A plurality of secondary air chambers, a concave well portion that is provided in at least one of the rim or the lid member and whose bottom portion is located radially inward of the bead seat, and communication that communicates with the tire main secondary air chamber and the secondary air chamber The Helmholtz resonance sound absorber is constituted by the auxiliary air chamber and the communication part.
JP 2002-79802 A

しかしながら、特許文献1に示すリムホイールは、副気室を構成する蓋部材と隔壁とが溶接等によって接合されたものであり、この接合部分において、自動車の走行時の振動に耐え得る機械的強度を確保することが困難であるという問題があった。また、蓋部材と隔壁を溶接等で接合する場合に十分な共鳴吸音効果を得るためには、副気室の気密性の確保が必要であり、極めて高度な溶接技術が必要となるため、実際に特許文献1に示すリムホイールを工業的に製造することは困難であるという問題があった。   However, in the rim wheel shown in Patent Document 1, the lid member and the partition wall constituting the auxiliary air chamber are joined by welding or the like, and the mechanical strength that can withstand vibration during driving of the automobile at this joined portion. There was a problem that it was difficult to ensure. In addition, in order to obtain a sufficient resonance sound absorption effect when joining the lid member and the partition wall by welding or the like, it is necessary to ensure the airtightness of the auxiliary air chamber, and an extremely advanced welding technique is required. In addition, there is a problem that it is difficult to industrially manufacture the rim wheel shown in Patent Document 1.

副気室の気密性を確保するためには、一般にシール剤を使用するが、シール剤は通常樹脂製であり、副気室を構成するアルミニウムなどの金属製と相違するため、分別回収する必要がある。   In order to ensure the airtightness of the secondary air chamber, a sealant is generally used. However, the sealant is usually made of resin, so it is different from metal such as aluminum that constitutes the secondary air chamber. There is.

本発明は、上述した課題に鑑みてなされたものであり、その目的とするところは、高い操縦安定性を確保しつつ車両への振動を抑制し、乗り心地がよく、車内騒音の低減を実現できるとともに、シール剤を使用せずにシール確保が可能で、分別回収の手間を省き、環境的に優れた車両用ホイールを提供することにある。   The present invention has been made in view of the above-described problems, and the object of the present invention is to suppress vibrations to the vehicle while ensuring high steering stability, to achieve a good ride comfort, and to reduce vehicle interior noise. In addition, it is possible to provide a vehicle wheel that can secure a seal without using a sealant, eliminates the trouble of sorting and collecting, and is environmentally superior.

However, the present invention is not construed as being limited thereto, and those skilled in the art do not depart from the scope of the present invention. Various changes, modifications and improvements can be made based on the knowledge.

図1は、本発明に係る車両用ホイールを模式的に示す平面図、図2は、本発明の車両用ホイールを模式的に示す断面図である。図1、図2に示すように,本発明に係る車両用ホイール1は、ディスク6の外周端にリム2が環状に形成されたものであり、リム2の外周面4上に複数の副気室3を備えている。図3に示すように、筒状部材の開口端面部が押し潰され閉塞されて内部が中空の副気室部材10が形成され、これが副気室3となる。これら複数の副気室部材10が、レーザービーム溶接等により、副気室部材10の環状方向(ホイール周方向)の両端部において、通常2箇所でリム2の外周面4と固着され、環状に配設される。   FIG. 1 is a plan view schematically showing a vehicle wheel according to the present invention, and FIG. 2 is a cross-sectional view schematically showing the vehicle wheel of the present invention. As shown in FIGS. 1 and 2, a vehicle wheel 1 according to the present invention has a rim 2 formed in an annular shape at the outer peripheral end of a disk 6, and a plurality of auxiliary air is formed on the outer peripheral surface 4 of the rim 2. A chamber 3 is provided. As shown in FIG. 3, the open end surface portion of the cylindrical member is crushed and closed to form a sub air chamber member 10 having a hollow interior, which becomes the sub air chamber 3. The plurality of auxiliary air chamber members 10 are fixed to the outer peripheral surface 4 of the rim 2 at two positions at both ends in the annular direction (wheel circumferential direction) of the auxiliary air chamber member 10 by laser beam welding or the like. Arranged.

ここで、「ホイール周方向」とは、図1中の矢印で示されるホイール周方向24を示し、「ホイール軸方向」とは、図2中の矢印で示されるホイール軸方向19を示す。   Here, “wheel circumferential direction” indicates a wheel circumferential direction 24 indicated by an arrow in FIG. 1, and “wheel axial direction” indicates a wheel axial direction 19 indicated by an arrow in FIG. 2.

次に、本発明に係る車両用ホイールの製造方法について説明する。まず、アルミニウム等の金属製材料から、押出成形により図4に示されるような複数の筒状部材11を得る。次に、図5に示されるように、筒状部材11の開口端面部12を押し潰して、図6のような端面部が閉塞された内部が中空の副気室部材10を得る。ここで、筒状部材11の開口端面部12を容易に押し潰すために、図4及び図7のように、筒状部材11の開口端面部12において、内側に折り畳まれるように湾曲用折り目部15を形成しておくことが好ましい。次いで、曲げ加工により、図3に示すような副気室部材10を得る。   Next, a method for manufacturing a vehicle wheel according to the present invention will be described. First, a plurality of cylindrical members 11 as shown in FIG. 4 are obtained from a metal material such as aluminum by extrusion. Next, as shown in FIG. 5, the open end surface portion 12 of the cylindrical member 11 is crushed to obtain a sub air chamber member 10 having a hollow interior with the end surface portion closed as shown in FIG. 6. Here, in order to easily crush the opening end surface portion 12 of the cylindrical member 11, as shown in FIGS. 4 and 7, the bending fold portion is folded inward at the opening end surface portion 12 of the cylindrical member 11. 15 is preferably formed. Next, the auxiliary air chamber member 10 as shown in FIG. 3 is obtained by bending.

上記のようにして得られた複数の内部中空副気室部材10を、リム2の外周面4上に環状に配設し、副気室部材10の環状方向(ホイール周方向)の両端部における中央個所14を、例えばレーザービーム溶接を行い、リム2の外周面4と固着することにより、本発明に係る車両用ホイールを製造することができる。   The plurality of internal hollow sub air chamber members 10 obtained as described above are annularly arranged on the outer peripheral surface 4 of the rim 2, and are formed at both ends of the sub air chamber member 10 in the annular direction (wheel circumferential direction). The vehicle wheel according to the present invention can be manufactured by, for example, performing laser beam welding on the central portion 14 and fixing it to the outer peripheral surface 4 of the rim 2.

なお、内部中空副気室部材10には、連通孔5を所定間隔に一つ以上穿設し、タイヤ主気室と連通孔5とによって共鳴吸収が可能なものとすることが好ましい。この連通孔5は複数の副気室3すべてに対して一つ以上穿設することが、上記共鳴吸収の効果をさらに向上させることができることから好ましい。この連通孔5は、あらかじめ内部中空副気室部材10に設けておくことが好ましい。   In addition, it is preferable that one or more communication holes 5 are formed at predetermined intervals in the internal hollow sub-air chamber member 10 so that resonance absorption can be performed by the tire main air chamber and the communication holes 5. It is preferable that one or more communication holes 5 be formed in all of the plurality of auxiliary air chambers 3 because the effect of resonance absorption can be further improved. This communication hole 5 is preferably provided in advance in the internal hollow auxiliary air chamber member 10.

本実施形態の車両用ホイールにおいては、ホイールを構成する材料について特に制限はないが、例えば、車両用ホイールとして必要な機械的強度を得ることができるとともに軽量であることから、軽合金を主成分とする金属であることが好ましく、具体的には、アルミニウム合金やマグネシウム合金を主成分とすることが好ましい。   In the vehicle wheel of the present embodiment, the material constituting the wheel is not particularly limited. For example, a light alloy can be obtained as a main component because it can obtain the mechanical strength necessary for a vehicle wheel and is lightweight. In particular, it is preferable that the main component is an aluminum alloy or a magnesium alloy.

また更に、本実施形態の車両用ホイールにおいては、内部中空副気室部材を構成する材料について特に制限はないが、例えば、内部中空副気室部材として必要な機械的強度を得ることができるとともに軽量であることから、熱可塑性樹脂、光可塑性樹脂、熱硬化性樹脂、光硬化性樹脂、金属等が好ましい。成形性を考慮すると熱(光)可塑性樹脂が好ましく、成形後(装着後)ホイールの熱による影響を考慮すると熱(光)硬化性樹脂もまた好ましい。金属としては、軽合金を主成分とする金属であることが好ましく、具体的には、アルミニウム合金やマグネシウム合金を主成分とすることが好ましい。材質として可塑性樹脂を用いた場合は、成形が容易であるという点において好ましい。筒状部材の開口端面部の押し潰しは、金属製の場合には機械プレスにより、また、樹脂製の場合には、加熱プレスにより容易に実施することができる。   Furthermore, in the vehicle wheel of the present embodiment, the material constituting the internal hollow sub-air chamber member is not particularly limited.

以上のように、リム外周面上に複数の副気室を備えた車両用ホイールを、それぞれ別体で製造したリムホイール及び内部中空副気室部材10によって作製できるため、極めて生産性に優れるとともに、機械的強度に優れ、バランスが良いことから、安定した走行を実現することが出来る。さらに、樹脂製のシール剤を使用せずに副気室のシールが可能であるため、分別回収を必要とせず、環境上極めて好ましい。   As described above, since the vehicle wheel having a plurality of auxiliary air chambers on the outer peripheral surface of the rim can be produced by the rim wheel and the internal hollow auxiliary air chamber member 10 which are separately manufactured, the productivity is extremely excellent. Because of its excellent mechanical strength and good balance, stable running can be realized. Furthermore, since the auxiliary air chamber can be sealed without using a resin sealant, separation and collection are not required, which is extremely preferable in terms of the environment.

さらに、本実施形態の車両用ホイールにおいては、図1及び図2の副気室3に連通する連通孔5が穿設され、この副気室3と連通孔5とによって良好な共鳴吸収の効果を得るためには、副気室3と連通孔5とが、下記式(1)の関係を満たすように構成されていることが好ましい。   Further, in the vehicle wheel of the present embodiment, a communication hole 5 communicating with the auxiliary air chamber 3 of FIGS. 1 and 2 is formed, and the effect of good resonance absorption is achieved by the auxiliary air chamber 3 and the communication hole 5.

図1及び図2において、本発明による副気室3と連通孔5とが、前記式(1)の関係を満たすように構成されることにより、本実施形態の車両用ホイールに装着したタイヤの空洞共鳴音と同程度の周波数となるように共鳴周波数を設定することが可能となり、タイヤの空洞共鳴音を減少させることができる。なお、本実施形態の車両用ホイールにおいて、副気室3の数が二つ以上であり、それぞれの副気室3に穿設された連通孔5の数が異なる場合には、前記式(1)におけるNは一つの副気室3に穿設する連通孔5の平均数(個)のことである。   1 and 2, the auxiliary air chamber 3 and the communication hole 5 according to the present invention are configured so as to satisfy the relationship of the above formula (1), so that the tire mounted on the vehicle wheel of the present embodiment It is possible to set the resonance frequency so as to have the same frequency as the cavity resonance sound, and to reduce the cavity resonance noise of the tire. In the vehicle wheel of the present embodiment, when the number of auxiliary air chambers 3 is two or more and the number of communication holes 5 formed in each auxiliary air chamber 3 is different, the above formula (1 N in) means the average number (pieces) of the communication holes 5 formed in one auxiliary air chamber 3.

If the total volume of the auxiliary air chamber 3 is less than 2% by volume, the effect of improving riding comfort and the effect of resonance absorption may decrease, and if it exceeds 25% by volume, the above-described resonance absorption is reduced. In the case of performing, the spring constant may be lowered with respect to the low frequency, and the attenuation may be reduced.

本発明に係る車両用ホイールによれば、車両用ホイールを作業性よく、かつ簡便、高精度に製造することができ、しかも、得られる車両用ホイールは、機械的強度にも優れ安定した走行を実現することが出来るため、工業上極めて有益である。   According to the vehicle wheel according to the present invention, the vehicle wheel can be manufactured with good workability, simply, and with high accuracy, and the obtained vehicle wheel has excellent mechanical strength and can travel stably. Since it can be realized, it is extremely useful industrially.
