Definitions

  • the present invention relates to an intake manifold formed by vibration-welding a plurality of joining members made of a synthetic resin.
  • Such an intake manifold is known in, for example, Japanese Utility Model Registration Application Laid-open No. 6-73368.
  • This intake manifold is formed by vibration-welding a first joining member and a second joining member.
  • first joining member a plurality of first intake pipe halves are integrally connected over their whole length, each of the first intake pipe halves forming a part of an intake pipe.
  • second joining member a plurality of second intake pipe halves are integrally connected over their whole length, each of the second intake pipe halves forming the remainder of the corresponding intake pipe.
  • an intake manifold by vibration-welding a first joining member made of a synthetic resin and a plurality of second joining members, the first joining member being formed by connecting in common at least one end of each of a plurality of intake pipe halves positioned at intervals from each other and each forming a part of an intake pipe, the second joining members being separate from each other and each forming the remainder of the corresponding intake pipe.
  • An intake manifold is constructed in this manner, the second joining members need to be managed individually, so that it is difficult to make the production efficiency high.
  • the second joining members may be misaligned relative to the first joining member during vibration welding.
  • the present invention has been achieved in view of the above-mentioned circumstances, and it is an object of the present invention to provide an intake manifold that improves the degree of freedom in the engine layout while suppressing the amount of synthetic resin, and that can be produced efficiently and with high precision.
  • an intake manifold including a first joining member made of a synthetic resin and a second joining member made of a synthetic resin.
  • the first joining member includes a plurality of first intake pipe halves disposed at intervals in parallel to each other, each forming a part of one of a plurality of intake pipes. At least one of the opposite ends of each of the plurality of first intake pipe halves is connected in common.
  • the second joining member includes a plurality of second intake pipe halves, each forming the remainder of the corresponding intake pipe and being connected to each other at bridging parts positioned in the middle in the longitudinal direction of the intake pipes.
  • the intake manifold is formed by vibration-welding the first joining member and the second joining member.
  • This arrangement allows comparatively wide gaps to be set between the plurality of intake pipes of the intake manifold, thereby alleviating restrictions on the engine layout.
  • adjacent intake pipes are connected to each other at least one of the opposite ends thereof and at the bridging parts that are in the middle in the longitudinal direction of the intake pipes, the amount of synthetic resin can be reduced in comparison with an intake manifold having a structure in which adjacent intake pipes are integrally connected over their whole length.
  • first joining member formed from the plurality of first intake pipe halves with their relative positions being fixed and the second joining member formed from the plurality of second intake pipe halves with their relative positions being fixed are vibration-welded together to form the intake pipes, an intake manifold can be produced efficiently and with high precision.
  • the intake manifold is arranged such that the bridging part includes a low-rigidity part that has a rigidity lower than that of parts adjacent thereto.
  • the warp and distortion can be absorbed by the low-rigidity part to correct the overall shape of the second joining member, thus preventing any displacement being caused in the vibration welded joint face to improve the welding quality.
  • FIGS. 1 to 4 show one embodiment of the present invention.
  • FIG. 1 is a perspective view of a surge tank and an intake manifold.
  • FIG. 2 is a perspective view of a first joining member.
  • FIG. 3 is a perspective view of a second joining member.
  • FIG. 4 is a cross section along line 4-4 in FIG. 1.
  • an intake manifold M which is connected to, for example, a four-cylinder engine (not illustrated), includes a plurality of, for example, four intake pipes 5 disposed in parallel to each other.
  • One end of each of the intake pipes 5 is connected in common to a surge tank 6.
  • Integrally provided on the other ends of the intake pipes 5 is a common engine mounting flange 9 via which the intake manifold M is connected to the engine.
  • the intake pipes 5 are disposed in parallel to each other in a shape such that they curve around, for example, substantially 180 degrees on the way from the surge tank 6 to the engine mounting flange 9.
  • the surge tank 6 is formed by vibration-welding an open end of a first tank half 7 made of a synthetic resin and opening upward, and an open end of a second tank half 8 made of a synthetic resin and opening toward the first tank half 7 along the entire periphery thereof.
  • Said one end of each of the intake pipes 5 of the intake manifold M is provided so as to be connected integrally and in common to one side of the first tank half 7.
  • Connected to one end, along the direction in which the intake pipes 5 are arranged, of the first tank half 7 is a conduit 10 for conducting air into the surge tank 6, the flow rate of the air being controlled by a throttle valve (not illustrated).
  • the intake manifold M is formed by vibration-welding first and second joining members 11 and 12 each made of a synthetic resin.
  • the first joining member 11 is formed by connecting in common at least one end (both ends in this embodiment) of the opposite ends of each of a plurality of, for example, four first intake pipe halves 13, which each form the main part of the corresponding intake pipe 5.
  • the first joining member 11 includes the first intake pipe halves 13, the first tank half 7, and the engine mounting flange 9.
  • One end of each of the first intake pipe halves 13 is connected integrally and in common to the first tank half 7.
  • the other end of each of the first intake pipe halves 13 is connected integrally to the common engine mounting flange 9.
  • the first intake pipes halves 13 are formed so that each has an opening 16 on the outer peripheral side of the curved part.
  • a joining flange 17 is integrally formed on the periphery of each of the openings 16 so as to project outward.
  • the second joining member 12 is formed by connecting a plurality of, for example, four second intake pipe halves 14 each forming the remainder of the corresponding intake pipe 5, via three bridging parts 15 positioned in the middle in the longitudinal direction of the intake pipes 5.
  • the second intake pipe halves 14 are formed so as to block the openings 16 of the first intake pipe halves 13. Integrally formed on the outer periphery of each of the second intake pipe halves 14 is a joining flange 18 that is joined to the joining flange 17 of the corresponding first intake pipe half 13.
  • the joining flanges 17 and 18 that correspond to each other are vibration-welded.
  • the bridging parts 15 are disposed in the curved parts in the middle in the longitudinal direction of the intake pipes 5, and connects together the second intake pipe halves 14.
  • a low-rigidity part 15a is provided in each of the bridging parts 15 in substantially the center along the direction in which the intake pipes 5 are arranged, the low-rigidity part 15a having an outwardly projecting curved shape so that the thickness of the low-rigidity part 15a can be made thinner than that on either side thereof, thereby lowering its rigidity relative to adjacent parts.
  • the intake manifold M is formed by vibration-welding the first joining member 11 and the second joining member 12.
  • the first joining member 11 is formed by connecting in common at least one (both in this embodiment) of the opposite ends of each of the plurality of, for example, four first intake pipe halves 13 disposed at intervals in parallel to each other and forming the main parts of the plurality of, for example, four intake pipes 5.
  • the second joining member 12 is formed by connecting, via the bridging parts 15 positioned in the middle in the longitudinal direction of the intake pipes 5, the plurality of, for example, four second intake pipe halves 14 each forming the remainder of the corresponding intake pipe 5.
  • adjacent intake pipes 5 are only connected to each other at least one (both in this example) of their opposite ends and by the bridging parts 15 that are in the middle in the longitudinal direction of the intake pipes 5.
  • the amount of synthetic resin to form the intake manifold M can therefore be reduced in comparison with an intake manifold having a structure in which adjacent intake pipes are integrally connected over their whole length.
  • first joining member 11 that is formed from the plurality of first intake pipe halves 13 with the relative positions thereof fixed
  • second joining member 12 that is formed from the plurality of second intake pipe halves 14 with the relative positions thereof fixed
  • the low-rigidity parts 15a that have a rigidity lower than that of the adjacent parts are provided in the bridging parts 15. Therefore, when warp and distortion that are caused in the second joining member are corrected by means of a backup member of the vibration welding die on the surface where the second joining member makes contact with the first joining member during vibration welding of the first and second joining members, the warp and distortion can be absorbed by the low-rigidity part so as to correct the overall shape of the second joining member 12, thus preventing any displacement in the vibration welded joint faces to improve the welding quality when producing the intake manifold M.
  • An intake manifold is formed by vibration-welding a first joining member made of a synthetic resin and a second joining member made of a synthetic resin.
  • the first joining member includes a plurality of first intake pipe halves disposed at intervals in parallel to each other, each forming a part of one of a plurality of intake pipes. At least one of the opposite ends of each of the plurality of first intake pipe halves is connected in common.
  • the second joining member includes a plurality of second intake pipe halves, each forming the remainder of the corresponding intake pipe and being connected to each other at a bridging part positioned in the middle in the longitudinal direction of the intake pipes.
  • the bridging part may be provided with a low-rigidity part that has a rigidity lower than that of parts adjacent thereto.
