Definitions

  • the invention relates to an intake air duct for an internal combustion engine of a motor vehicle with an air calming space, in particular a raw air shell of an intake air filter.
  • 4 shows a partial section of a third exemplary embodiment, shown only in principle, through an intake air duct according to the invention in a motor vehicle, namely in particular the air calming space, and
  • FIG. 5 shows view X from FIG. 4.
  • the intake air to be supplied to the internal combustion engine also not shown, thus reaches the intake air filter 1 via this intake snorkel 2, is subjected to filtering there and is finally fed to the internal combustion engine via an outlet connection 3, which is part of the intake air filter 1 and to which an air guide hose (not shown) is connected fed.
  • the intake air filter 1 has an unfiltered air shell 5 forming an air calming space 4, in which a suitable filter element 6 is suspended above the calming space 4.
  • the intake air filter 1 is closed off at the top by the so-called clean air tray 7, which is placed on the raw air tray 5 and into which the filter element 6 usually extends to a certain extent.
  • the intake air filter 1 is also not shown in section in this area. Is shown in section, however the unfiltered air shell 5 with the intake snorkel 2 opening into it and with the rotary flap 8 according to the invention provided in a wall of the unfiltered air shell 5.
  • this rotary flap 8 is provided in a wall 9 of the raw air shell 5 or the air calming space 4, which wall extends geodetically from bottom to top.
  • This rotary flap 8 is inserted with its guide housing 10 into a suitable recess 11 in the wall 9, wherein this recess 11 can also be referred to as a passage opening 11.
  • the guide housing 10 carries a shaft 12 'forming an axis of rotation 12 for the rotary flap 8.
  • the rotary flap 8 is divided into two so-called vanes 8a, 8b by this shaft 12 'or by the axis of rotation 12.
  • the rotary flap 8 can be pivoted about the axis of rotation 12 from the position shown, the lower wing 8a moving outwards with respect to the calming space 4, while the upper wing 8b inwards, i.e. H. is swung into the calming room 4. After this pivoting movement has been carried out, the cutout or passage opening 11 is opened.
  • the rotary flap 8 of its usual closed position is shown, in which it is held by a spring element 14 designed as a leg spring, which is supported on the one hand on the wing 8a and on the other hand on the guide housing 10.
  • the recess 11 (or passage opening 11) in the raw air shell 5 is thus sealed. If a surge of spray water reaches the calming space 4 via the intake snorkel 2, this water collects in the lower area of this calming space 4 and thus exerts pressure on the wing 8a.
  • This causes the rotary flap 8 to be pivoted in the direction of the arrow 13, ie the wing 8a moves outwards, while at the same time the wing 8b is pivoted inwards.
  • the splashing water can flow over the lower half of the now open recess / passage opening 11 had accumulated in the calming space 4, flow away, while an ambient air flow can reach the air calming space 4 via the upper section of the recess 11 lying in the area of the wing 8b in the direction of the arrow 16.
  • the rotary flap 8 thus takes over two functions in a particularly advantageous manner. On the one hand, it is ensured that, for example, water can be removed from the calming space 4, and that at the same time intake air for the internal combustion engine can flow into the calming space 4, which is necessary, for example, when the motor vehicle is to pass through a large and deep puddle and via the suction snorkel 2 water gets into the raw air tray 5 over a longer period of time.
  • the rotary flap 8, and in particular the wing 8b is located geodetically above the inlet opening of the intake snorkel, so that when driving through a deep puddle there is no danger that water will also enter the intake air filter 1 or the calming space via the open recess 11 4 arrives.
  • the intake air filter 1 is usually located at a relatively protected location within the engine compartment of the motor vehicle, so that in the region of this rotary valve 8, even under unfavorable conditions, there is guaranteed to be no splash water which could penetrate into the raw air shell 5 according to the direction of the arrow 16.
  • the rotary flap 8 is likewise arranged with its guide housing 10 in a recess 11 in a wall 9 'of the unfiltered air shell 5, but this is the wall 9' around the lower boundary wall of the unfiltered air shell 5.
  • a splash of water that reaches the calming space 4 via the intake snorkel 2 could lay down in equal parts on the two wings 8a, 8b of the rotary flap 8, thereby opening the rotary flap automatically 8 would not take place.
  • the wing 8b of the rotary flap 8 which can be pivoted inwards, is sealed off here against possible accumulation of, for example, splash water.
  • This partitioning is embodied here in the form of a connecting piece 17 'which is adapted to the dimensions of the wing 8b and which can be constructed from a plurality of so-called partition walls 17; however, in the simplest case, a single partition wall 17 for partitioning the wing 8b which can be pivoted inwards can also be used be enough.
  • the connector 17 'with its partition or its partitions 17 is fastened to the guide housing 10 of the rotary flap 8, or the guide housing 10 is a correspondingly shaped plastic injection molded part with molded nozzle 17' or molded partitions 17
  • the splash water splash already mentioned several times in the unfiltered air shell 5 this water collects, inter alia, on the wing 8a of the rotary flap 8 and, due to its gravity, causes this rotary flap 8 to open.
  • the wing 8a is again pivoted outwards, while the wing 8b moves inwards - into the calming space 4.
  • the accumulated spray water can thus flow away in the direction of the arrow 15, while in the direction of the arrow 16 intake air - without additional spray water - can get into the unfiltered air shell 5 of the intake air filter 1.
  • the rotary flap 8 is brought back into its illustrated closed position by the spring element 14 and held in this position, so that the intake air then reaches the intake air filter 1 via the intake snorkel 2 as usual.
  • Both of the previously described exemplary embodiments use the same principle, namely that, for example, spray water that enters the unfiltered air shell 5 of the intake air filter opens the rotary flap 8 due to its gravity in such a way that, on the one hand, the spray water can flow out in the direction of the arrow 15 and, on the other hand, an ambient air flow in the direction of the arrow 16 can be supplied.
  • the rotary flap 8 is provided in a wall 9 or 9 'of a so-called air calming space 4 in the intake air duct of the internal combustion engine. Only in this way can gravity, for example of the penetrating spray water, come into its own.
  • the structure of the rotary flap 8 with its guide housing 10 can be seen even better .
  • the guide housing 10 has a circumferential web 19 on which the rotary flap 8, which is formed here at right angles or squares, bears with the edges of the wings 8a, 8b with the interposition of a sealing element 20 fastened on the edges.
  • Fig. 3b you can also see the arrangement of the spring element 14 designed as a leg spring, which is supported on the one hand on the guide housing 10 and on the other hand on the outside of the wing 8a, whereby the rotary flap 8 is usually held in its closed position.
  • the spring force of the spring element 14 is dimensioned such that when it accumulates foreign substances, in particular water, on the inside of the wing 8a, the described opening of the rotary flap 8 takes place according to the direction of the arrow 13.
  • an alternative design of the connector 17 ' is also shown in dashed lines.
  • the partition 17 serving to seal off the wing 8b against a possible accumulation of foreign substances is designed as a flow outlet funnel 17 ′′ in order to have favorable inflow conditions whenever an ambient air stream 16 reaches the unfiltered air tray 5 when the rotary flap 8 is open.
  • a so-called sniffer valve 18 is also provided in the deepest point of the raw air tray 5, through which small residual amounts of spray water can still run off.
  • a cooler 23 is arranged, in front of which there is an air collecting space 24. Not only is the cooler 23 supplied with cooling air from this air collecting space 24, but at the same time the intake air for the internal combustion engine driving the motor vehicle, which is arranged in the engine compartment 21 but is not shown, is branched off. For this purpose, a branch duct 25 is provided above the cooler 23.
  • This branch duct 25 opens out via an inflow opening 26 into a so-called air calming space 4, which also has an outflow opening 28, to which an intake duct 29 (see FIG. 5) connects, which ultimately leads to the intake system of the internal combustion engine.
  • the inflow opening 26 and the outflow opening 28 are practical with respect to the calming space 4 arranged as far apart as possible. As shown in FIG. 5, the inflow opening 26 is at the left end and the outflow opening 28 is at the right end of the calming space 4 which extends transversely in the engine compartment 21, ie transversely to the vehicle longitudinal axis.
  • the air calming space 4 has outer walls 9, one of which has a passage opening 11.
  • This passage opening 11 is usually closed by a rotary flap 8, so that the intake air brought in via the inflow opening 26 is also safely discharged again via the outflow opening 28.
  • the passage opening 11 is located in the outer wall 9 with the largest surface which has both a surface section close to the inflow opening 26 and a surface section close to the outflow opening 28.
  • the passage opening 11 is provided at the bottom with respect to the calming space.
  • the rotary flap 8 can be rotated or pivoted about an axis of rotation 12 extending obliquely through this rotary flap. Since the axis of rotation 12 runs obliquely through the rotary flap 8 - in the exemplary embodiment shown here, the rotary flap 8 is approximately rectangular and the axis of rotation 12 coincides with the diagonal of this rectangle - two so-called rotary flap wings 8a, 8b are formed.
  • the rotary flap 8 is mounted on its axis of rotation 12 such that when this rotary flap 8 is pivoted, one rotary flap wing 8a can be pivoted outward in the direction of the arrow 13a, while the other rotary flap wing 8b inward in the calming space 4 as shown in the direction of the arrow 8b is pivoted.
  • the arrangement is such that the rotary flap wing 8a, which is pivoted outwards in the direction of the arrow 13a, has its area center of gravity FS a near the inflow opening 26, while the area center of gravity FS b of the rotary flap wing 8b, which can be pivoted inward in the direction of the arrow 13b, is in the vicinity of the outflow opening 28 (cf. FIG. 5).
  • the air calming space 4 or in particular the same Passage opening 11 at such a point within the engine compartment 21, at which no splashing water can be found with certainty.
  • the air calming space 4 is namely geodetically arranged as far up as possible in the engine compartment 21, the passage opening 11 being provided on the side facing away from the end wall 36 of the motor vehicle.
  • the rotary flap 8 therefore also performs two functions here. On the one hand, it is ensured that, for example, water, but also other foreign substances that get into the intake air duct of the internal combustion engine, can or can be removed from the calming space 4, and that, at the same time, intake air for the internal combustion engine can flow into the calming space 4, which, for example is then necessary if the motor vehicle is to drive through a large and deep puddle and water is entering the branch duct 25 over a longer period of time via the air collecting space 24.
  • two effects are used to open the rotary flap 8, namely the dynamic effect in that the foreign substances entering the air calming space 4 via the inflow opening 26 primarily hit the rotary flap wing 8a which can be pivoted outwards.
  • the influence of gravity is also used in that these foreign substances or water, which enters the calming space 4, accumulate or accumulate at its geodetically lowest point and thus likewise cause the rotary flap 8 to pivot.
  • the rotary flap wing 8a is geodetically considered below the rotary flap wing 8b.
  • the rotary flap 8 is provided in an outer wall 9 of the so-called air calming space 4, which extends essentially geodetically from bottom to top. Only with the help of such a calming space 4 can the gravity, for example of the penetrating spray water (or general foreign matter), come into its own. In this context it is also Particularly advantageous if the outflow opening 28 is provided as far as possible geodetically above the calming space 4.
  • This spring element 14 can of course be designed in different ways, but it is particularly advantageous if this spring element 14 simultaneously acts as an axis of rotation 12 in the sense of a functional combination.
  • this spring element 14 can be designed, for example, as a torsion spring bar.
