Definitions
- the present invention relates to an intake manifold, especially for internal combustion engines, according to the preamble of claim 1.
- An intake device for an internal combustion engine is described in German Patent Application DE 199 44 855 and in the corresponding international application PCT 01/21 053 AI.
- This device consists of a mounting flange for mounting on a cylinder head of the machine and of several intake pipes that open into a common collecting space.
- the fastening flange forms a first component in which the intake pipes end.
- a second component is provided, in which the intake pipes extend, and finally a third component is provided which closes off 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 attached to the first component.
- the third component is positively attached to the second component.
- the components fastened to one another in this way are brought into contact with one another along sealing surfaces and, with appropriate means, the sealing surfaces connected to each other for example by friction welding of a known type.
- Intake manifolds of this type are mainly designed so that they can be made in plastic and there is therefore the problem of adapting the intake manifold to be manufactured in its design in such a way that the corresponding casting mold with a minimum of slides to create rear s can be manufactured and on the other hand to make the intake manifold itself with a minimum amount 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 of which are to be supplemented by a cover, who carries the complementary half-shells to complete the pipe parts in the base body.
- this channel can be used to introduce a U-shaped web into the same, the beam of which is connected to the Channel base is brought into contact and the legs of which form extensions of the contact surface of the abutting half-shells of the cover, whereby a contact is made between both the free edges of the half-shells of the cover with the free edges of the gusset-like wall and the web beam with the channel base.
- each half-shell and the outer surface of the U-shaped web is expediently slightly larger than the channel base in such a way that there is enough material for one There is a weld between the web beam and the channel base.
- this welding mat is formed by two webs which protrude from the channel base in such a way that the welding material can flow into the space between the two webs, a further indentation between the two webs being left for the welding itself ,
- FIGS. 2 and 3 each show cross sections of an intake manifold according to the invention in an embodiment in two different positions of the intake manifold itself, which are offset by 90 ° to one another.
- reference number 1 indicates the base body of an intake manifold according to the prior art, for example for a gasoline engine.
- the base body has a multiplicity of semi-chal-shaped longitudinal depressions 11-14 which are lined up with one another, for example, along a curved axis from a plenum to a mounting flange on a cylinder head of the engine. Between the individual recesses 11-14 lying one against the other, webs 15 are excluded at the level of the free edge thereof in the body 10, which are interrupted by grooves 16 on the edge region 17 of the recesses.
- Each depression 11-14 has a base with a minimum distance 18 from the end face of the body 10 facing away from the depressions themselves.
- the depressions 11-14 can be supplemented to form circumferentially closed tubes by means of a cover 19 which is formed with half-shells 20-23 which are connected to one another by webs 24, from 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 achieved by welding the webs 15 and 25, for example with frictional movements.
- FIGS solution proposed in order to avoid the problem of waste of material between the intake pipes due to the edges on the side of the base body 10 between the half-shells, and to make the entire intake manifold lighter, according to the invention, which is shown in FIGS solution proposed:
- a multiplicity of depressions in the present case four, from 111 to 114 are excluded in a base body 110.
- a channel 115 is excluded, which extends essentially in accordance with the longitudinal extent of the depressions 111-114.
- webs 118 protrude from the bottom of each channel 115, which alternate with grooves 119.
- each channel 115 The distance of the base of each channel 115 from the end face of the body on the opposite side of the depressions expediently corresponds essentially to the minimum distance of each depression from the end face itself. In this way there is 111-114 between each depression and the adjacent one Channel 115 formed a gusset-like wall 121.
- the base body 110 can be assigned a cover 122 which is formed by a multiplicity 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 18 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 next to the leg 128 on the free edge of the gusset-like wall 126 during friction welding pressed between bridge 126 and channel bottom 115.
- an extension 132 extends from one of the sides of the base body, which can be connected by welding to an arm 133 which projects from the side of the outer half-shell and which is not followed by any further half-shells: with such a design various additional parts of known type are connected to the intake manifold.
- connection described can also be provided between a large number of containers or pipes, which is not intended for suction.
