Description
【０００１】0001
本考案は、内燃機関のオイルパン取付装置に関する。 The present invention relates to an oil pan mounting device for an internal combustion engine.
【０００２】0002
内燃機関のオイルパンの取付装置の従来例として、図７〜図１０に示すような ものがある。 すなわち、シリンダブロック１下部には凹状のオイルパン２が配設され、オイ ルパン２外周のフランジ部２Ａはシリンダブロック１の外周部にスチ−ル製の背 板３を介してボルト４により締付固定されている。また、ボルト４の締付固定後 、図８のＡに示すように、背板３とオイルパン２の外周部とを所定間隔毎に溶接 し、締付面圧を均一化するようにしている。 Conventional examples of oil pan mounting devices for internal combustion engines include those shown in Figures 7 to 10. There is something. That is, a concave oil pan 2 is provided at the bottom of the cylinder block 1, and the oil pan 2 is provided at the bottom of the cylinder block 1. The flange part 2A on the outer periphery of Lupin 2 is attached to the outer periphery of the cylinder block 1 with a steel backing. It is tightened and fixed with bolts 4 through plate 3. Also, after tightening and fixing bolt 4, , as shown in FIG. 8A, the back plate 3 and the outer periphery of the oil pan 2 are welded at predetermined intervals. This is done to equalize the tightening surface pressure.
【０００３】 また、前記背板３は、図９に示すように、鋼製の平板をシャー切断することに より形成される。0003 In addition, the back plate 3 is made by shear cutting a steel flat plate as shown in FIG. formed by
【０００４】0004
しかし、平板をシャー切断して背板３を形成すると、背板３の隅部にエッジ部 Ｂが形成されるので、そのエッジ部Ｂが図１０に示すようにオイルパン２と接触 する。このため、エッジ部Ｂの面圧が高くなるので、エンジン稼働中の振動によ りフレッテイングを起こして疲労起点となり亀裂が発生し耐久性に劣るという不 具合がある。 However, when the back plate 3 is formed by shear cutting a flat plate, there are edges at the corners of the back plate 3. B is formed, so the edge part B contacts the oil pan 2 as shown in FIG. do. For this reason, the surface pressure on the edge part B increases, so vibrations during engine operation This causes fretting, which becomes a starting point for fatigue and cracks, resulting in poor durability. There's something wrong with me.
【０００５】 本考案は、このような実状に鑑みてなされたもので、背板にエッジ部が発生す るのを防止できるオイルパン取付装置を提供することを目的とする。[0005] This invention was developed in view of the above-mentioned circumstances, and is designed to prevent edges from forming on the backboard. It is an object of the present invention to provide an oil pan mounting device that can prevent oil pan mounting.
【０００６】[0006]
このため、本考案は、オイルパンをシリンダブロックに取り付ける背板を、断 面が略円形状の丸棒鋼材を該丸棒鋼材の軸線に沿って両側部から圧延して形成さ れた板状部材により、形成するようにした。 For this reason, the present invention requires cutting off the back plate that attaches the oil pan to the cylinder block. It is formed by rolling a round steel bar with a substantially circular surface from both sides along the axis of the round steel bar. The structure is made of a plate-like member that is made of aluminum.
【０００７】[0007]
このように、丸棒鋼材を圧延して形成された部材により背板を形成することに より、背板の隅部にエッジ部が発生するのを防止するようにした。 In this way, the back plate is formed from a member formed by rolling a round steel bar. This prevents the formation of edges at the corners of the backboard.
【０００８】[0008]
以下に、本考案の一実施例を図１〜図６に基づいて説明する。 図１において、シリンダブロック１１下部の外周部には凹状のオイルパン１２ 外周のフランジ部１２Ａ上壁が当接され、オイルパン１２の外周部下壁には背板 １３が当接されている。そして、オイルパンのフランジ部１２Ａは背板１３と共 にボルト（図示せず）によりシリンダブロック１１に締め付け固定されている。 前記背板１３は図２に示すようにオイルパン１３の外周形状に合わせて曲げ加工 により折曲形成されている。 An embodiment of the present invention will be described below based on FIGS. 1 to 6. In FIG. 1, a concave oil pan 12 is provided on the outer periphery of the lower part of the cylinder block 11. The upper wall of the outer periphery of the flange portion 12A is in contact with the outer periphery of the oil pan 12, and a back plate is attached to the outer periphery of the oil pan 12. 13 are in contact with each other. The flange portion 12A of the oil pan and the back plate 13 are It is fastened and fixed to the cylinder block 11 with bolts (not shown). The back plate 13 is bent to match the outer peripheral shape of the oil pan 13 as shown in FIG. It is formed by bending.
【０００９】 次に、背板１３の製造方法を説明すると、図３に示すように、丸棒鋼材１４を 圧延ローラ１５Ａ，１５Ｂにより丸棒鋼材１４の軸線に沿って両側部から圧延し て所定厚みの平板１４Ａを形成する。このとき、丸棒鋼材１４は背板１３に必要 な厚さ，幅が得られる寸法のものを使用する。 このようにして、平板１４Ａを丸棒鋼材１４から形成すると、平板１４は図４ に示すように隅部がＲ状に形成される。そして、平板１４Ａをオイルパン１２の 形状に合わせて曲げ加工により折曲形成し、背板１３を形成する。この折曲時に は背板１３の内周縁部に図５に示すように肉厚部Ｃが形成されるので、図６に示 すように背板１３をプレス加工して平面性を確保する。[0009] Next, to explain the manufacturing method of the back plate 13, as shown in FIG. The round steel bar 14 is rolled from both sides along the axis using rolling rollers 15A and 15B. A flat plate 14A having a predetermined thickness is formed. At this time, the round steel bar 14 is necessary for the back plate 13. Use one with dimensions that allow for appropriate thickness and width. When the flat plate 14A is formed from the round steel bar material 14 in this way, the flat plate 14 is shown in FIG. The corners are formed in a rounded shape as shown in FIG. Then, attach the flat plate 14A to the oil pan 12. The back plate 13 is formed by bending according to the shape. At this bending As shown in FIG. 6, a thick portion C is formed on the inner peripheral edge of the back plate 13 as shown in FIG. The back plate 13 is pressed to ensure flatness.
【００１０】 以上説明したように、丸棒鋼材１４を圧延加工して形成された平板１４Ａにて 背板１３を形成するようにしたので、背板１３の隅部が図２に示すようにＲ状に 形成されるため、背板１３をオイルパン１２に取付けたときに背板１３の隅に応 力が集中するのを防止でき、もって耐久性を向上できる。0010 As explained above, the flat plate 14A formed by rolling the round steel bar 14 Since the back plate 13 is formed so that the corners of the back plate 13 are rounded as shown in FIG. Because of this, when the back plate 13 is attached to the oil pan 12, the corners of the back plate 13 This prevents concentration of force and improves durability.
【００１１】[0011]
本考案は、以上説明したように、オイルパンをシリンダブロックに取付ける背 板を、丸棒鋼材を圧延して形成される板状部材により、形成するようにしたので 、背板の隅部をＲ状に形成できるため、応力集中を防止でき、耐久性を向上でき る。 As explained above, the present invention is based on the backbone for attaching the oil pan to the cylinder block. Since the plate is formed from a plate-shaped member formed by rolling a round steel bar material, , since the corners of the back plate can be formed into an R shape, stress concentration can be prevented and durability can be improved.
