Definitions

  • the present invention relates to an intake manifold, in particular for internal combustion engines, according to the preamble of claim 1.
  • a suction device for an internal combustion engine consists of a mounting flange for attachment to a cylinder head of the machine and a plurality of intake pipes, which open into a common plenum.
  • the mounting flange forms a first component in which the intake pipes end.
  • a second component in which the intake pipes extend and finally a third component is provided, which closes the second component and forms the shape of the intake pipes.
  • the components are connected to one another in such a way that the second component is positively secured to the first component.
  • the third component is positively fastened.
  • the so fastened together components are brought along sealing surfaces in contact with each other, and with appropriate means, the sealing surfaces are joined together, for example by friction welding of known type.
  • intake manifolds of this type are designed to be manufactured in plastic, and therefore the problem arises of adapting the intake manifold to be manufactured in such a way that the corresponding mold can be manufactured with a minimum of sliders for creating undercuts and on the other hand to carry out the intake manifold itself with a minimum of plastic to be used.
  • the object of the present invention is to solve this problem and to propose an intake manifold, which is designed such that the material consumption for the injection molding of the base body of the intake manifold is further reduced, the intake pipes are to be supplemented by a lid which carries the complementary half-shells to complete the pipe parts in the base body.
  • this channel By a channel is formed between two tube parts in the base body, wherein between the tube parts only a gore-like wall is raised, which rises from the body wall, this channel can be used to introduce into the same a U-shaped web whose Beam is brought into contact with the channel bottom and the legs of which form extensions of the contact surface of the abutting half shells of the lid, wherein contact is made both the free edges of the half-shells of the lid with the free edges of the gusset-like wall and the web bar with the channel bottom.
  • the distance between the free edge of each half-shell and the outer surface of the U-shaped web is so slightly larger compared to the channel bottom that sufficient material for a weld between the web bar and the channel bottom is present.
  • This welding material is formed in an expedient embodiment by two webs, which project from the channel base such that the welding material can flow into the space between the two webs, with a further indentation between the two webs for the weld itself is left.
  • reference numeral 10 indicates the base body of a prior art intake manifold, for example, for a gasoline engine.
  • the base body has a multiplicity of half-shell-shaped longitudinal recesses 11-14 which adjoin one another, for example extending along a curved axis from a collecting space to a fastening flange on a cylinder head of the engine. Between the individual adjoining recesses 11-14 webs 15 are excluded in the height of the free edge thereof in the body 10, which are interrupted by grooves 16 in an edge region 17 of the recesses 11-14.
  • Each recess 11-14 has a bottom with a minimum distance 18 from the end remote from the wells itself of the body 10.
  • the depressions 11-14 can be supplemented to form circumferentially closed tubes by means of a lid 19, which is formed with half-shells 20-23, which are interconnected by webs 24, of which grooves 26 forming webs 25 protrude. If the edges of the half-shells 20-23 are brought into contact with the edges of the depressions 11-14, the closed profiles of the various intake pipes of the intake manifold are obtained by welding the webs 15 and 25, for example under frictional movements.
  • a plurality of recesses are excluded from 111 to 114.
  • a respective channel 115 is excluded, which extends essentially in accordance with the longitudinal extent of the recesses 111-114. From the bottom of each channel 115 jump in this case webs 118, which alternate with grooves 119.
  • the distance of the bottom of each channel 115 from the front of the body on the opposite side of the recesses substantially corresponds to the minimum distance of each recess from the front itself. In this way is between each Well 111 - 114 and the adjacent channel 115 a gore-like wall 121 is formed.
  • the base body 110 may be associated with a lid 122 formed by a plurality of half-shells 123-126, the number of which corresponds to the number of depressions 111-114.
  • the half-shells 123-126 are each connected by a substantially U-shaped web 127, from which the legs 128 extend from the free edge of each half-shell to the beam 129, from which webs 130 extend, which overlap with the webs 118 come into contact when the free edge is pressed next to the leg 12 B respectively on the free edge of the gusset-like wall 121 in friction welding between the web 127 and the bottom of the channel 115.
  • an extension 132 which can be connected by welding to an arm 133 which projects from the side of the outer half-shell, which follow no further half-shells
  • Inlet manifold different accessories known type can be connected.

Claims (4)

  1. Collecteur d'admission notamment destiné à des moteurs à combustion interne, comprenant un corps de base (110) qui présente une pluralité de renfoncements longitudinaux en forme de demi-coque (111 - 114), qui s'étendent étant placés l'un à côté de l'autre, et un couvercle (122) qui a des demi-coques (123 - 126), qui sont connectées entre elles par des entretoises (127) et qui, avec les renfoncements longitudinaux (111-114) forment des tuyaux d'aspiration, caractérisé en ce que les entretoises (127) sont formées en forme d'U et qu'entre les renfoncements placés l'un à côté de l'autre (111 - 114) du corps de base (110) est formé chaque fois un canal (115) qui est destiné à recevoir chaque fois une entretoise (127), dont la poutre (129) est à mettre en contact avec le fond du canal pour une soudure et dont les côtés (128) forment des prolongations de la surface de contact des demi-coques (123 - 126) avec le corps de base (110).
