Description

本発明は、車輌用のステアリングナックルやリヤナックル（リヤキャリアとも言う）に代表される、車軸やサスペンション部品の支持に関与する機械構造としてのナックルに関する。特に、ナックルを構成する部品の相互接合構造に関するものである。   The present invention relates to a knuckle as a mechanical structure related to support of an axle and suspension parts, represented by a steering knuckle and a rear knuckle (also referred to as a rear carrier) for a vehicle. In particular, the present invention relates to an interconnection structure of parts constituting the knuckle.

例えば特許文献１は、いわゆるＦＦ車のリヤ従動輪用ストラット型サスペンションのストラットを支持するナックルの構造を開示する。このナックルは、それぞれ金属板をプレス成形して得たインナナックル及びアウタナックルの二つの部材（部品）から構成されている。そして、インナナックル及びアウタナックルをそれらの周壁が互いに重ね合わさるように係合させた状態でその重ね合わせ部の所定箇所に溶接を施すことで、内部が中空なナックルを完成させている。   For example, Patent Document 1 discloses a knuckle structure that supports a strut of a strut suspension for a rear driven wheel of a so-called FF vehicle. The knuckle is composed of two members (parts) of an inner knuckle and an outer knuckle obtained by press-molding a metal plate. Then, the inner knuckle and the outer knuckle are engaged so that their peripheral walls are overlapped with each other, and welding is performed at a predetermined portion of the overlapping portion, thereby completing a knuckle having a hollow inside.

しかしながら、二つのナックル構成部品を溶接にて結合すると、次のような不都合が生じ得る。例えば、各ナックル構成部品に鋳鉄等のカーボン含有量の多い鉄系材料を採用した場合、溶接時の熱の影響で溶接部位及びその近傍に材質変化（即ち局部的な組成変化）が起こり、肝心の溶接部位が脆くなって強度が低下することがある。また、二つのナックル構成部品間で融点が大きく異なる金属を採用した場合（例えば一方が鉄で他方がアルミニウムという組合せの場合）、溶接時に低融点金属だけが先に溶融してしまい十分な溶接強度を得られない。更には、各ナックル構成部品に溶接性に問題のない金属又はその組合せを採用した場合でも、溶接時の熱で製品が変形して寸法精度の低下を招くことがある。このように、ナックル構成部品の加熱を不可避的に伴う溶接による限り、上述のような不都合を解消できない。   However, when the two knuckle components are joined by welding, the following inconveniences may occur. For example, when iron-based materials with a high carbon content such as cast iron are used for each knuckle component, material changes (ie, local composition changes) occur at and near the weld site due to the effect of heat during welding. The welded part may become brittle and the strength may decrease. In addition, when a metal with a significantly different melting point is used between two knuckle components (for example, when one is iron and the other is aluminum), only the low-melting point metal melts first during welding, resulting in sufficient welding strength. I can't get it. Furthermore, even when a metal having no problem in weldability or a combination thereof is adopted for each knuckle component, the product may be deformed by heat during welding, leading to a reduction in dimensional accuracy. As described above, the above-described inconveniences cannot be solved as long as welding is inevitably accompanied by heating of the knuckle component.

本発明をステアリングナックルに具体化した一実施形態を図１〜図４を参照しつつ説明する。図１に示すようにステアリングナックルは、第１のナックル構成部品としての左側板材１０Ａ及び右側板材１０Ｂ、並びに、第２のナックル構成部品としての正面板材２０の３つの部品から構成されている。   An embodiment in which the present invention is embodied in a steering knuckle will be described with reference to FIGS. As shown in FIG. 1, the steering knuckle is composed of three parts: a left side plate member 10A and a right side plate member 10B as first knuckle components, and a front plate member 20 as a second knuckle component.

左側板材１０Ａ及び右側板材１０Ｂは、材料となる金属板をプレス成形して得た板金部品である。左側板材１０Ａ及び右側板材１０Ｂの各々には、正面板材２０と向き合う端縁から正面板材２０の方に突出するように、４つの第１係合突片１１及び２つの第２係合突片１２が突出形成されている。これら合計６つの係合突片１１，１２は、材料金属板をプレス成形した際に各板材の本体部１３と同時成形された部位であり、機械的外力を及ぼすことで板材本体部１３に対して略直角に折り曲げ可能な部位である。また、左側板材１０Ａ及び右側板材１０Ｂの各々の上端部には、ストラット型サスペンションの一部を取り付けるための取り付け部１４が設けられている。   The left side plate member 10A and the right side plate member 10B are sheet metal parts obtained by press forming a metal plate as a material. Each of the left side plate member 10A and the right side plate member 10B has four first engagement protrusions 11 and two second engagement protrusions 12 so as to protrude from the edge facing the front plate member 20 toward the front plate member 20. Projectingly formed. These six engaging protrusions 11 and 12 are portions simultaneously formed with the body portion 13 of each plate material when the material metal plate is press-molded, and exert a mechanical external force on the plate body body portion 13. This is a part that can be bent at a substantially right angle. Moreover, the attachment part 14 for attaching a part of strut type suspension is provided in each upper end part of 10 A of left side board | plate materials, and the right side board | plate material 10B.

正面板材２０も、材料となる金属板をプレス成形して得た板金部品である。正面板材２０の本体部２１の略中央には、車軸を通すための車軸用開口２２が貫通形成されている。この車軸用開口２２を取り囲む位置には、左側板材１０Ａの４つの第１係合突片１１及び右側板材１０Ｂの４つの第１係合突片１１を挿入受け容れ可能な合計８つの係合孔２３が貫通形成されている。また、正面板材２０の上端部２４には、左側板材１０Ａの２つの第２係合突片１２及び右側板材１０Ｂの２つの第２係合突片１２を進入受け容れ可能な合計４つの係合凹部２５が切り欠き形成されている。これらの係合孔２３及び係合凹部２５は、材料金属板をプレス成形した際に正面板材の本体部２１及び上端部２４と同時成形された部位である。また、正面板材２０の左端には、ディスクブレーキ用のキャリパを取り付けるための上下一対の取り付け部２６が設けられている。   The front plate 20 is also a sheet metal part obtained by press-molding a metal plate as a material. An axle opening 22 through which the axle passes is formed through substantially the center of the main body 21 of the front plate member 20. A total of eight engagement holes that can receive and accept the four first engagement protrusions 11 of the left side plate member 10A and the four first engagement protrusions 11 of the right side plate member 10B are provided at positions surrounding the axle opening 22. 23 is formed through. Further, the upper end portion 24 of the front plate member 20 has a total of four engagements capable of entering and receiving the two second engagement protrusions 12 of the left plate member 10A and the two second engagement protrusions 12 of the right plate member 10B. A recess 25 is formed in the cutout. These engagement holes 23 and engagement recesses 25 are portions formed simultaneously with the main body portion 21 and the upper end portion 24 of the front plate material when the material metal plate is press-formed. A pair of upper and lower mounting portions 26 for mounting a disc brake caliper is provided at the left end of the front plate member 20.

左側板材１０Ａ、右側板材１０Ｂ及び正面板材２０の３部品からステアリングナックルを組み立てる際には、先ず図示しない治具を用いて、左側板材１０Ａ及び右側板材１０Ｂ間に所定間隔を確保しつつ両者を移動不能に保持する。この保持状態では図１に示すように、左側板材１０Ａの２つの第２係合突片１２と右側板材１０Ｂの２つの第２係合突片１２とが互いに向き合う。そこへ正面板材２０を組み付ける。すると、左側板材１０Ａの４つの第１係合突片１１及び右側板材１０Ｂの４つの第１係合突片１１がそれぞれ対応する正面板材２０の各係合孔２３内に進入し、各係合突片１１が係合孔２３から正面板材２０の正面側に突出する。同様に、左側板材１０Ａの２つの第２係合突片１２及び右側板材１０Ｂの２つの第２係合突片１２がそれぞれ対応する正面板材２０の各係合凹部２５内に進入し、各係合突片１２が係合凹部２５から正面板材２０の正面側に突出する。   When assembling the steering knuckle from the three components of the left side plate member 10A, the right side plate member 10B, and the front plate member 20, first, using a jig (not shown), the two are moved while securing a predetermined interval between the left side plate member 10A and the right side plate member 10B. Keep impossible. In this holding state, as shown in FIG. 1, the two second engagement protrusions 12 of the left side plate member 10A and the two second engagement protrusions 12 of the right side plate member 10B face each other. The front plate 20 is assembled there. Then, the four first engagement protrusions 11 of the left side plate member 10A and the four first engagement protrusions 11 of the right side plate member 10B enter the respective engagement holes 23 of the corresponding front plate member 20, respectively. The projecting piece 11 projects from the engagement hole 23 to the front side of the front plate member 20. Similarly, the two second engagement protrusions 12 of the left side plate member 10A and the two second engagement protrusions 12 of the right side plate member 10B enter the respective engagement recesses 25 of the corresponding front plate member 20, respectively. The mating piece 12 projects from the engaging recess 25 to the front side of the front plate member 20.

そして、図２〜図４に示すように、第１及び第２の係合突片１１，１２をそれぞれ正面板材２０の表面に接するように略直角に折り曲げる。図３は、第１の係合突片１１を折り曲げることによる左側板材１０Ａと正面板材２０の本体部２１との結合状況を示し、図４は、第２の係合突片１２を折り曲げることによる左側板材１０Ａ及び右側板材１０Ｂと正面板材２０の上端部２４との結合状況を示す。これら折り曲げの結果、折れ曲がった係合突片１１，１２によって正面板材２０が左側及び右側板材１０Ａ，１０Ｂに抱きかかえられ、３部品が相互離脱不能に一体化される。その後、左側及び右側板材１０Ａ，１０Ｂを保持していた治具を取り外すことでステアリングナックルが完成する。   Then, as shown in FIGS. 2 to 4, the first and second engaging protrusions 11, 12 are bent at substantially right angles so as to contact the surface of the front plate member 20. FIG. 3 shows a connection state between the left side plate member 10 </ b> A and the main body 21 of the front plate member 20 by bending the first engagement protrusion piece 11, and FIG. 4 is a result of bending the second engagement protrusion piece 12. A connection state between the left side plate member 10A and the right side plate member 10B and the upper end part 24 of the front plate member 20 is shown. As a result of the bending, the front plate member 20 is held by the left and right plate members 10A and 10B by the bent engagement protrusions 11 and 12, and the three parts are integrated so that they cannot be separated from each other. Thereafter, the steering knuckle is completed by removing the jigs holding the left and right plate members 10A and 10B.

このように本実施形態によれば、左側板材１０Ａ、右側板材１０Ｂ及び正面板材２０の３部品を組み合わせた状態で、左側及び右側板材の第１及び第２係合突片１１，１２を略直角に折り曲げるという非加熱的な機械加工により、上記３部品を一体結合してステアリングナックルを製造できるので、溶接等の加熱を伴う加工が不要となる。それ故、仮に各部品の材料金属板として鋳鉄等のカーボン含有量の多い鉄系材料の金属板を用いた場合でも、熱の影響による材質変化の発生を心配する必要がなく、加熱による強度低下や寸法精度低下のない強度及び寸法精度の良好なステアリングナックルを得ることができる。   As described above, according to the present embodiment, the first and second engaging protrusions 11 and 12 of the left and right side plate members are substantially perpendicular to each other in a state where the three parts of the left side plate member 10A, the right side plate member 10B, and the front plate member 20 are combined. Since the steering knuckle can be manufactured by integrally connecting the above three parts by non-heating machining such as bending into two, processing with heating such as welding becomes unnecessary. Therefore, even if a metal plate made of iron-based material with a high carbon content such as cast iron is used as the material metal plate for each part, there is no need to worry about the occurrence of material changes due to the effect of heat, and the strength decreases due to heating. In addition, it is possible to obtain a steering knuckle with good strength and dimensional accuracy without any deterioration in dimensional accuracy.

また、加熱操作の不要な接合構造の採用により、各部品ごとの材料選択の幅が広がり、ステアリングナックルの性能（又は性質）を多様化することが可能となる。   Further, by adopting a joining structure that does not require a heating operation, the range of material selection for each part is expanded, and the performance (or properties) of the steering knuckle can be diversified.

例えば、第１のナックル構成部品（左側板材１０Ａ及び右側板材１０Ｂ）の構成材料として非高張力鋼（例：炭素鋼）を選択する一方で、第２のナックル構成部品（正面板材２０）の構成材料として高張力鋼を選択する。この場合には、高張力鋼からなる第２のナックル構成部品によって、ナックルの機械的強度及び剛性の飛躍的向上が図られると共に、非高張力鋼からなる第１のナックル構成部品によって、係合突片１１，１２の折り曲げ加工のし易さを担保しつつナックルの機械的強度及び剛性の向上が図られる。   For example, while selecting non-high-tensile steel (example: carbon steel) as the constituent material of the first knuckle component (left plate member 10A and right plate member 10B), the configuration of the second knuckle component (front plate member 20) Select high-strength steel as material. In this case, the second knuckle component made of high-strength steel can dramatically improve the mechanical strength and rigidity of the knuckle, and the first knuckle component made of non-high-strength steel can be engaged. The mechanical strength and rigidity of the knuckle can be improved while ensuring the ease of bending the projecting pieces 11 and 12.

また例えば、第１のナックル構成部品（左側板材１０Ａ及び右側板材１０Ｂ）の構成材料として鉄系材料（例：炭素鋼）を選択する一方で、第２のナックル構成部品（正面板材２０）の構成材料としてアルミニウム系材料を選択する。この場合には、アルミニウム系材料からなる第２のナックル構成部品によって、ナックル全体としての軽量化が図られると共に、鉄系材料からなる第１のナックル構成部品によって、係合突片１１，１２の折り曲げ加工のし易さを担保しつつナックルの機械的強度及び剛性の向上が図られる。つまり、強度及び剛性の向上とナックル全体としての軽量化とを両立させることができる。   In addition, for example, an iron-based material (eg, carbon steel) is selected as the constituent material of the first knuckle component (left plate member 10A and right plate member 10B), while the second knuckle component (front plate member 20) is configured. An aluminum-based material is selected as the material. In this case, the weight of the entire knuckle can be reduced by the second knuckle component made of the aluminum-based material, and the engagement protrusions 11 and 12 can be reduced by the first knuckle component made of the iron-based material. The mechanical strength and rigidity of the knuckle can be improved while ensuring the ease of bending. That is, both improvement in strength and rigidity and weight reduction as a whole knuckle can be achieved.

（変更例）本発明の実施形態を以下のように変更してもよい。
図１〜図４に示した実施形態では、第１のナックル構成部品（左側板材１０Ａ及び右側板材１０Ｂ）の一部である係合突片１１，１２を略直角に折り曲げることを示したが、ナックル構成部品の一部の折り曲げ態様はこれに限定されるものではない。例えば図５に示すように、第１のナックル構成部品３１の一部（下端部３１ａ）で第２のナックル構成部品３２の端部の上下面を挟み込むように第１のナックル構成部品３１の一部を折り曲げてもよい。あるいは図６に示すように、第１のナックル構成部品３１の一部（端部）と第２のナックル構成部品３２の一部（端部）とを重ね合わせた後、ロール状に巻き取るように両ナックル構成部品３１，３２の一部を折り曲げてもよい。図５及び図６に示すような折り曲げ態様でも、第１及び第２のナックル構成部品３１，３２を相互離脱不能に一体化させることができる。 (Modification) The embodiment of the present invention may be modified as follows.
In the embodiment shown in FIGS. 1 to 4, the engagement protrusions 11 and 12 that are part of the first knuckle component (the left side plate member 10 </ b> A and the right side plate member 10 </ b> B) are bent at substantially right angles. The folding manner of a part of the knuckle component is not limited to this. For example, as shown in FIG. 5, one part of the first knuckle component 31 is sandwiched between the upper and lower surfaces of the end of the second knuckle component 32 by a part (lower end portion 31a) of the first knuckle component 31. The part may be bent. Alternatively, as shown in FIG. 6, a part (end part) of the first knuckle component 31 and a part (end part) of the second knuckle component 32 are overlapped and then wound in a roll shape. Alternatively, part of both knuckle components 31 and 32 may be bent. The first and second knuckle components 31 and 32 can also be integrated so as not to be separated from each other even in the folding manner as shown in FIGS.
