Definitions

  • This invention relates to an oil pan structure in an engine.
  • bosses are formed integral with a vertical wall in an oil pan made by casting and an engine component is supported on the bosses.
  • the conventional oil pan structure in an engine described above includes a system shown in JP-A-H06-108919.
  • the oil pan comprises a bottom plate, a vertical wall integrally protruding upwardly from the outer edge of the bottom plate, an outwardly extending flange formed integral with the vertical wall at the protruding end and fixed to the lower end of the crankcase, a pair of bosses located below the outwardly extending flange and integrally projecting laterally outwardly from the outside surface of the vertical wall for supporting an engine component, and a connecting piece disposed between these two bosses and formed integral with the vertical wall in the vertical middle portion thereof for integrally connecting the two bosses; and the bottom plate, vertical wall, outwardly extending flange, bosses and connecting piece are formed by casting. Oil retained in the oil pan is supplied to engine portions, for lubrication.
  • the two bosses are reinforced by the connecting piece, thereby improving supporting strength of the two bosses to support the engine component.
  • a connecting piece is formed integral with the vertical wall, together with a pair of bosses, so that the overall volume of these bosses and connecting piece is fairly large compared with the middle portion of the vertical wall to be integrated with these parts. Therefore, shrinkage cavities are apt to be produced during casting of the oil pan on the inside surface of the middle portion of the vertical wall to be integrated with the bosses and the connecting piece. This is unfavorable to the strength of the vertical wall.
  • an object of examples of this invention is to prevent shrinkage cavities from being produced when a pair of bosses are provided on the outside surface of a vertical wall of an oil pan made by casting and these bosses are reinforced.
  • Another object of examples of this invention is to facilitate machining work when the projecting ends of the bosses are machined flat.

  • the oil pan 8 comprises a pair of bosses 21, 21 integrally projecting laterally outwardly from the vertical middle portion of the outside surface of the vertical wall 27 such that the axial centers 22 are approximately perpendicular to the outside surface of the vertical wall 27 and located below the outwardly extending flange 28, a connecting piece 29 disposed between the bosses 21, 21, as viewed in profile of the oil pan 8 (Fig. 1), and extending on a line connecting the axial centers 22, 22 for integrally connecting the bosses 21, 21, and a pair of ribs 30, 30 provided integrally between the bosses 21, 21 and portions of the vertical wall 27 below the bosses 21, 21 for reinforcing the bosses 21, 21.
  • the bottom plate 26, vertical wall 27, outwardly extending flange 28, bosses 21, 21, connecting piece 29 and ribs 30, 30 of the oil pan 8 are formed integral with each other by casting with aluminum material.
  • each boss 21 is formed integral with the outwardly extending flange 28, so that the boss 21 is reinforced by the outwardly extending flange 28.
  • the oil pan 8 When the oil pan 8 is viewed in profile (Fig. 1), the upper surface and the lower surface of one boss 21 are each inclined such that it heads upwardly as they are apart from the other boss 21, and the inclination is approximately 40-50°.
  • the oil pan 8 When the oil pan 8 is viewed in plan (Fig. 6), the outside surface of one boss 21 opposite the other boss 21 is inclined such that it is apart from the other boss 21 as it approaches the vertical wall 27, and the inclination is approximately 40-50°.
  • the protruding edge of each rib 30 from the vertical wall 27 is inclined such that it approaches the vertical wall 27 as it heads downwardly, and the inclination is approximately 40-50°.
  • the connecting piece 29 is not integrated with the vertical wall 27 at the vertical middle portion as in the prior art, so that a shrinkage cavity is prevented from being produced in the inside surface of the middle portion of the vertical wall 27 during casting of the oil pan 8, preventing the problem with a strength to the vertical wall 27.
  • the outwardly extending flange 28 has a sufficiently large thickness compared with the vertical wall 27, so that even if a shrinkage cavity is to be produced in the outwardly extending flange 28, this doesn't raise any problem with a strength when the outer edge of the outwardly extending flange 28 and the inner edge 29a of the connecting piece 29 are formed integral with each other.
  • the whole of the inner edge 29a of the connecting piece 29 is integrated with the outer edge of the outwardly extending flange 28 and no vertical through-opening is provided between the outwardly extending flange 28 and the inner edge 29a.
  • removal work is generally required for eliminating burrs produced on the opening edge of this opening by casting.
  • the outwardly extending flange 28 and the inner edge 29a of the connecting piece 29 are wholly integrated, so that removal work of eliminating burrs is dispensed with because of no opening between them.
  • the outer edge 29b of the connecting piece 29 in the projecting direction of the boss 21 has a thick plate shape extending approximately in the horizontal direction as a whole, and the inner edge 29a is thinner than the outer edge 29b.
  • the outwardly extending flange 28 and the inner edge 29a of the connecting piece 29 are integrated, as described above, the volume of the inner edge 29a of the connecting piece 29 is suppressed to a small value, so that shrinkage cavities are prevented more reliably from being produced in the outward extending flange 28 or portions of the vertical wall 27 in the vicinity of the outwardly extending flange 28.
  • the projecting end faces 21a, 21a of the bosses 21, 21, and the end face 29c of the outer edge 29b of the connecting piece 29 in the projecting direction of the bosses 21, 21 are flush with each other and constitute a continuous flat surface (21a, 29c) extending in the direction perpendicular to the axial center 22 of the screw hole 23.
  • machining work for flattening the projecting end faces 21a of the bosses 21 can be carried out continuously and in a short time because of the end face 29c of the connecting piece 29 being included in the machining range.
  • machining work for flattening the projecting end faces 21a of the bosses 21 can be performed easily.
  • bosses 21 are not limited to a pair of bosses, but three or more bosses may be provided.
  • An aspect of the present invention provides an oil pan structure in an engine comprising a bottom plate, a vertical wall integrally protruding upwardly from outer edges of the bottom plate, an outwardly extending flange formed integral with the vertical wall at the protruding end and fixed to the lower end of a crankcase, a pair of bosses located below the outwardly extending flange and integrally projecting laterally outwardly from the outside surface of the vertical wall for supporting a component of an engine, and a connecting piece disposed between these two bosses for connecting the two bosses integrally, and said bottom plate, vertical wall, outwardly extending flange, bosses and connecting piece being formed by casting, wherein;
  • the inner edge of said connecting piece on the side of said vertical wall is formed integral with said outwardly extending flange.
  • the connecting piece is not integrated with the vertical wall at the vertical middle portion as in the prior art, so that a shrinkage cavity is prevented from being produced in the inside surface of the middle portion of the vertical wall during casting of the oil pan, preventing the problem with a strength to the vertical wall.
  • outwardly extending flange has a sufficiently large thickness compared with the vertical wall, so that even if a shrinkage cavity is to be produced in the outwardly extending flange, this doesn't raise any problem with strength when the outer edge of the outwardly extending flange and the inner edge of the connecting piece are formed integral with each other.
  • said inner edge of said connecting piece is thinner than the outer edge of said connecting piece in the projecting direction of said bosses.
  • the outwardly extending flange and the inner edge of the connecting piece are integrated, as described above, the volume of the inner edge of the connecting piece is suppressed to a small value, so that shrinkage cavities are prevented more reliably from being produced in the outward extending flange or portions of the vertical wall in the vicinity of the outwardly extending flange.
  • machining work is performed individually to these faces, but by contrast, according to the present invention, machining work for flattening the projecting end faces of the bosses can be carried out continuously and in a short time because of the end face of the connecting piece being included in the machining range.
  • machining work for flattening the projecting end faces of the bosses can be performed easily.
  • an oil pan 8 comprises a bottom plate 26, a vertical wall 27 integrally protruded upwardly from outer edges of the bottom plate 26, an outwardly extending flange 28 formed integral with the vertical wall 27 at the protruded end and fixed to the lower end of a crankcase 2, a pair of bosses 21, 21 located below the outwardly extending flange 28 and integrally projecting laterally outwardly from the outside surface of the vertical wall 27 for supporting a component 14 of an engine 1, and a connecting piece 29 disposed between these two bosses 21, 21 for connecting the two bosses 21, 21 integrally.
  • the bottom plate 26, vertical wall 27, outwardly extending flange 28, bosses 21, 21 and connecting piece 29 are formed by casting.
