Description

リンク部材Link member
　本発明は、巻きカラーと、巻きカラーに溶接接合された接合部材とを有するリンク部材に関する。 The present invention relates to a link member having a winding collar and a joining member welded to the winding collar.
　部材を支持したり、負荷を伝達したりするために、回転あるいは揺動自在に取り付けられるリンク部材が広く用いられている。例えば、自動車においては、車両用サスペンション機構にリンク部材が組み込まれている。車両用サスペンション機構は、トレーリングアームやサスペンションアームなどのアーム部材を有し、アーム部材にはアーム部材を車体に軸支する中空円筒形状のカラー部材が接合されている。アーム部材およびカラー部材からリンク部材が構成されている。カラー部材は、一般に中空パイプを切断することによって製造され、アーム部材の先端に溶接接合されている（例えば、特許文献１参照。）。 Link members that are rotatably or pivotably attached are widely used to support the members and transmit loads. For example, in a car, a link member is incorporated in a suspension mechanism for a vehicle. The suspension system for vehicles has arm members, such as a trailing arm and a suspension arm, and the hollow cylindrical collar member which pivotally supports an arm member to a vehicle body is joined to the arm member. The link member is composed of the arm member and the collar member. The collar member is generally manufactured by cutting a hollow pipe and is welded to the tip of the arm member (see, for example, Patent Document 1).
特開２００３－３００４０５号公報Japanese Patent Application Publication No. 2003-300405
　カラー部材のような中空円筒部材のコストを低減するために、短冊状の板材を巻いて板材の両端面を突き合わせて円筒形状に成形することによって、中空円筒部材を製造することが行われている。突き合わせた両端面が開かないように、両端面に設けたクリンチ部の嵌め合いによって両端面を接合している。カラー部材についても、短冊状の板材を巻いて円筒形状に成形した巻きカラーがある。 In order to reduce the cost of a hollow cylindrical member such as a collar member, it is practiced to manufacture a hollow cylindrical member by winding a strip-shaped plate member, butting both end surfaces of the plate member to form a cylindrical shape. . Both end faces are joined by the fitting of the clinch part provided in the both end faces so that the both end faces which abutted do not open. As for the color member, there is also a wound collar formed by winding a strip-shaped plate material into a cylindrical shape.
　リンク部材のカラー部材に巻きカラーを適用する場合には、巻きカラーの突き合わせた両端面が、リンク部材に作用する荷重によって開かないようにしなければならない。しかしながら、クリンチ部の嵌め合いだけでは両端面の接合を維持できない虞がある。 When applying a wrap collar to the collar member of the link member, the butted end faces of the wrap collar must be prevented from opening due to the load acting on the link member. However, there is a possibility that joining of both end faces can not be maintained only by fitting the clinch portion.
　カラー部材のコスト低減を通してリンク部材の低コスト化に寄与するために、リンク部材のカラー部材に巻きカラーを適用でき、かつ、リンク部材に荷重が作用しても巻きカラーの突き合わせた両端面が開くことを防止したリンク部材の実現が要請されている。 In order to contribute to the cost reduction of the link member through the cost reduction of the collar member, the winding collar can be applied to the collar member of the link member, and the opposing end surfaces of the winding collar open even if a load is applied to the link member. There is a demand for the realization of a link member that has been prevented.
　本発明は、上記要請に応えるべくなされたものであり、カラー部材に巻きカラーを適用したリンク部材であって、リンク部材に荷重が作用しても巻きカラーの突き合わせた両端面が開くことを防止したリンク部材を提供することを目的とする。 The present invention has been made to meet the above requirements, and is a link member in which a winding collar is applied to a collar member, and prevents opening of the butt end surfaces of the winding collar even if a load is applied to the link member. It is an object of the present invention to provide a link member.
　上記目的を達成する本発明のリンク部材は、巻きカラーと、巻きカラーに溶接接合された接合部材とを有するリンク部材である。前記巻きカラーは、短冊状の板材を巻いて前記板材の両端面を突き合わせて円筒形状に成形され、前記両端面に設けたクリンチ部の嵌め合いによって前記両端面が接合されている。前記接合部材は、前記巻きカラーに接合される接合端面を備え、前記接合端面が前記両端面を跨いで前記巻きカラーに突き当てられ、前記接合端面が前記両端面を跨いで前記巻きカラーに溶接接合されている。 The link member of the present invention which achieves the above object is a link member having a winding collar and a joining member welded to the winding collar. The winding collar is formed into a cylindrical shape by winding strip-shaped plate members and abutting both end surfaces of the plate members, and the both end surfaces are joined by fitting of clinch portions provided on the both end surfaces. The joining member includes a joining end face joined to the winding collar, the joining end face abuts the winding collar across the both end faces, and the joining end face welds the winding collar across the both end faces It is joined.
　本発明によれば、接合部材の接合端面が巻きカラーの両端面を跨いで巻きカラーに溶接接合されていることから、巻きカラーの突き合わせた両端面が、リンク部材に作用する荷重によって開くことを防止できる。クリンチ部の嵌め合いの結合力も加わり、巻きカラーの両端面の接合を維持でき、リンク部材のカラー部材に巻きカラーを適用することが可能となる。したがって、カラー部材に巻きカラーを適用したリンク部材であって、リンク部材に荷重が作用しても巻きカラーの突き合わせた両端面が開くことを防止したリンク部材を提供することができる。巻きカラーを適用できるため、パイプ材料からカラー部材を成形する場合に比べて、カラー部材のコスト低減を図ることができ、これを通してリンク部材の低コスト化に寄与することができる。 According to the present invention, since the joining end face of the joining member is welded and joined to the winding collar across the end faces of the winding collar, the butted end faces of the winding collar open due to the load acting on the link member. It can prevent. The coupling force of the clinch portion fitting is also added, and the joining of the both end faces of the winding collar can be maintained, and the winding collar can be applied to the collar member of the link member. Therefore, it is a link member which applied a winding collar to a collar member, and can provide a link member which prevented that the butt end surfaces which buttling of a winding collar opened even if a load acts on a link member. Since the wound collar can be applied, the cost of the collar member can be reduced as compared with the case of molding the collar member from the pipe material, and the cost of the link member can be reduced through this.

The lower member 23 is arranged to close the recess of the upper member 22 and prevents the deformation of the upper member 22. A hollow cylindrical collar member 40 for supporting the trailing arm 20 on the vehicle body is joined to the trailing arm 20.
　本実施形態にあっては、リンク部材５０は、カラー部材４０およびトレーリングアーム２０から構成されている。 In the present embodiment, the link member 50 is composed of the collar member 40 and the trailing arm 20.
　カラー部材４０には、巻きカラー４１を適用している。巻きカラー４１は、短冊状の板材４２を巻いて板材４２の両端面４３、４４を突き合わせて円筒形状に成形されている。巻きカラー４１の両端面４３、４４に設けたクリンチ部４５の嵌め合いによって両端面４３、４４が接合されている。 A wound collar 41 is applied to the color member 40. The winding collar 41 is formed into a cylindrical shape by winding a strip-shaped plate member 42 and abutting both end surfaces 43 and 44 of the plate member 42. Both end surfaces 43 and 44 are joined by fitting of the clinch part 45 provided in the both end surfaces 43 and 44 of the winding collar 41. As shown in FIG.
　トレーリングアーム２０は、巻きカラー４１に接合される接合端面２５を備える接合部材に相当している。トレーリングアーム２０は、接合端面２５が巻きカラー４１の両端面４３、４４を跨いで巻きカラー４１に突き当てられている。トレーリングアーム２０は、接合端面２５が両端面４３、４４を跨いで巻きカラー４１に溶接接合されている。図２（Ｂ）に符号２６を付した部分が溶接個所である。 The trailing arm 20 corresponds to a joining member provided with a joining end face 25 joined to the winding collar 41. The trailing end face 20 of the trailing arm 20 abuts against the winding collar 41 across the end faces 43 and 44 of the winding collar 41. The trailing end face 20 of the trailing arm 20 is joined by welding to the winding collar 41 so that the joining end face 25 straddles both end faces 43 and 44. The part which attached | subjected the code | symbol 26 to FIG. 2 (B) is a welding location.
　溶接接合の長さは、巻きカラー４１の円周方向の約３分の１の長さである。巻きカラー４１との接触面である接合端面２５の外周に沿って、巻きカラー４１とトレーリングアーム２０とを自動溶接機などを用いてアーク溶接してリンク部材５０を製造する。 The length of the weld joint is about one third the circumferential direction of the winding collar 41. The link member 50 is manufactured by arc welding the winding collar 41 and the trailing arm 20 along the outer periphery of the joint end surface 25 which is a contact surface with the winding collar 41 using an automatic welder or the like.
　トレーリングアーム２０の接合端面２５が巻きカラー４１の両端面４３、４４を跨いで巻きカラー４１に溶接接合されていることから、巻きカラー４１の突き合わせた両端面４３、４４が、リンク部材５０に作用する荷重によって開くことを防止できる。クリンチ部４５の嵌め合いの結合力も加わり、巻きカラー４１の両端面４３、４４の接合を維持でき、リンク部材５０のカラー部材４０に巻きカラー４１を適用することが可能となる。 Since the joining end face 25 of the trailing arm 20 is welded and joined to the winding collar 41 straddling both end surfaces 43 and 44 of the winding collar 41, the butted end surfaces 43 and 44 of the winding collar 41 are connected to the link member 50. It can prevent opening by the load which acts. The coupling force of the fitting of the clinch portion 45 is also added, and the bonding of both end surfaces 43 and 44 of the winding collar 41 can be maintained, and the winding collar 41 can be applied to the collar member 40 of the link member 50.
　したがって、カラー部材４０に巻きカラー４１を適用したリンク部材５０であって、リンク部材５０に荷重が作用しても巻きカラー４１の突き合わせた両端面４３、４４が開くことを防止したリンク部材５０を提供することができる。巻きカラー４１を適用できるため、パイプ材料からカラー部材４０を成形する場合に比べて、カラー部材４０のコスト低減を図ることができ、これを通してリンク部材５０の低コスト化に寄与することができる。 Therefore, the link member 50 in which the winding collar 41 is applied to the collar member 40, the link member 50 is prevented from opening both end surfaces 43 and 44 where the winding collar 41 abuts even if a load is applied to the link member 50. Can be provided. Since the wound collar 41 can be applied, the cost of the collar member 40 can be reduced as compared to the case where the collar member 40 is formed of a pipe material, and the cost of the link member 50 can be reduced through this.
　トレーリングアーム２０を巻きカラー４１に溶接接合する前に、巻きカラー４１の突き合わせた両端面４３、４４を溶接接合することも考えられる。しかしながら、溶接ステージを別途追加しなければならず、製造コストの増加を招いてしまう。そこで、本実施形態では、巻きカラー４１の両端面４３、４４を溶接接合していない。この場合であっても、巻きカラー４１の突き合わせた両端面４３、４４が、リンク部材５０に作用する荷重によって開くことはない。 It is also conceivable to weld the butted opposite end faces 43, 44 of the winding collar 41 prior to welding the trailing arm 20 to the winding collar 41. However, the welding stage has to be added separately, resulting in an increase in manufacturing cost. So, in this embodiment, the welding joining of the both end surfaces 43 and 44 of the winding collar 41 is not carried out. Even in this case, the butted end surfaces 43 and 44 of the winding collar 41 are not opened by the load acting on the link member 50.
　トレーリングアーム２０は、中空部２７を間に挟んで向かい合う２つの壁部２８、２９を有している。トレーリングアーム２０の２つの壁部２８、２９は、巻きカラー４１の両端面４３、４４を跨ぎ、かつ、クリンチ部４５を間に挟んで向かい合う位置において巻きカラー４１に溶接接合されている。 The trailing arm 20 has two wall portions 28 and 29 facing each other with the hollow portion 27 interposed therebetween. The two wall portions 28 and 29 of the trailing arm 20 straddle both end faces 43 and 44 of the winding collar 41 and are welded to the winding collar 41 at positions facing each other with the clinch portion 45 interposed therebetween.
　かかる構成によれば、巻きカラー４１に溶接接合されたトレーリングアーム２０の接合端面２５がクリンチ部４５を囲っていることから、クリンチ部４５の嵌め合いの結合力を高強度に維持でき、巻きカラー４１の突き合わせた両端面４３、４４がリンク部材５０に作用する荷重によって開くことを一層防止できる。 According to this configuration, since the joining end face 25 of the trailing arm 20 welded to the winding collar 41 surrounds the clinch portion 45, the coupling force of the clinching portion 45 can be maintained with high strength, and the winding is performed. It is possible to further prevent the butt end surfaces 43, 44 of the collar 41 from opening due to the load acting on the link member 50.
　以上説明したように、本実施形態のリンク部材５０によれば、クリンチ部４５の嵌め合いによって両端面４３、４４が接合された巻きカラー４１と、巻きカラー４１に接合される接合端面２５を備え接合端面２５が両端面４３、４４を跨いで巻きカラー４１に溶接接合されたトレーリングアーム２０と、を有している。このため、カラー部材４０に巻きカラー４１を適用したリンク部材５０であって、リンク部材５０に荷重が作用しても巻きカラー４１の突き合わせた両端面４３、４４が開くことを防止したリンク部材５０を提供することができる。巻きカラー４１を適用できるため、パイプ材料からカラー部材４０を成形する場合に比べて、カラー部材４０のコスト低減を図ることができ、これを通してリンク部材５０の低コスト化に寄与することができる。 As described above, according to the link member 50 of the present embodiment, the winding collar 41 to which the both end faces 43 and 44 are joined by the fitting of the clinch portion 45 and the joining end face 25 joined to the winding collar 41 The joining end face 25 has a trailing arm 20 welded and joined to the winding collar 41 across the end faces 43 and 44. For this reason, the link member 50 in which the winding collar 41 is applied to the collar member 40, and the load does not act on the link member 50 prevents the end surfaces 43 and 44 where the butting collar 41 butts open. Can be provided. Since the wound collar 41 can be applied, the cost of the collar member 40 can be reduced as compared to the case where the collar member 40 is formed of a pipe material, and the cost of the link member 50 can be reduced through this.
　トレーリングアーム２０は、中空部２７を間に挟んで向かい合う２つの壁部２８、２９を有し、２つの壁部２８、２９が、巻きカラー４１の両端面４３、４４を跨ぎ、かつ、クリンチ部４５を間に挟んで向かい合う位置において巻きカラー４１に溶接接合されている。このため、巻きカラー４１に溶接接合されたトレーリングアーム２０の接合端面２５がクリンチ部４５を囲っていることから、クリンチ部４５の嵌め合いの結合力を高強度に維持でき、巻きカラー４１の突き合わせた両端面４３、４４がリンク部材５０に作用する荷重によって開くことを一層防止できる。 The trailing arm 20 has two wall portions 28 and 29 facing each other with the hollow portion 27 interposed therebetween, and the two wall portions 28 and 29 straddle both end faces 43 and 44 of the winding collar 41 and clinch It is joined by welding to the winding collar 41 in the position which opposes on both sides of the part 45 in between. For this reason, since the joining end face 25 of the trailing arm 20 welded and joined to the winding collar 41 surrounds the clinch portion 45, the coupling force of the fitting of the clinch portion 45 can be maintained with high strength. It is possible to further prevent the end surfaces 43, 44 butted from opening due to the load acting on the link member 50.
　接合部材２０が車両用サスペンション機構のアーム部材に適用され、巻きカラー４１がアーム部材を車体に軸支するカラー部材４０に適用されている。したがって、カラー部材４０およびアーム部材から構成される車両用のリンク部材５０の低コスト化を図ることができる。 The joining member 20 is applied to an arm member of a suspension mechanism for a vehicle, and the winding collar 41 is applied to a collar member 40 for pivotally supporting the arm member on a vehicle body.
