Description
Technical field
The present invention relates to a kind of suction device for motor vehicle, it comprises that at least one is by air intake duct bagThe air intake duct enclosing, effectively air intake duct length can change, this air intake duct comprises that one along tubular axis lineThe pipe configuration component extending, this pipe configuration component has the first opening being positioned on the first axial location.
Background technology
For example by DE1576022A known a kind of such suction device. DE3630488A1 also illustrates a kind of characteristic suction device of the preamble with claim 1.
Two sections of described open source literatures illustrate respectively a kind of suction device, air intake duct in this suction deviceHydromechanical effective length can be according in coefficient with well-known suction device routinelyThe revolution of burn engine changes. Wherein prove useful: upper along with the revolution of explosive motorRise and shorten or extend along with the decline of revolution air intake duct or general the hydromechanical of air inlet pipe haveEffect length.
Be that well-known suction device demonstrates shortcoming or makes by the open source literature of the prior art of quotingThe secondary specialized school personnel that study them face technical difficulty:
First, with its knot together with hydromechanical effective air intake duct length of well-known suction deviceStructure length also changes, thus for the variation of the structure length of well-known air inlet pipe must beIn the enging cabin of motor vehicle, provide sufficient structure space according to intake manifold length maximum, that occur.The length of this air inlet pipe normally occurring in the time of low motor revolution. But in the operation of explosive motorThe length of middle air inlet pipe is not maximum length more than the major part of running time, but according to conventionallyThe centre occurring that is in operation is the length of a relative maximum length shortening to high revolution. Therefore existThe structure space providing in enging cabin is fully used not yet in effectly.
Secondly, above-cited open source literature shows due to pipe configuration component or duct arrangement assembly(Leitungsanordnung) internal combustion along with attached of relative displacement air inlet pipe respect to one another is sent outThe revolution of motivation can continually varying length. The length of this stepless continuous causing by straight-line displacementAlthough change the optimum length that makes in theory to regulate into each revolution of explosive motor an air inlet pipeBecome possibility. But in fact the straight line mobility of stepless continuous causes by first and coaxial secondSealing problem in the axial part section of the common air intake duct covering of pipe configuration component, thereby due to notThe reason that enters the infiltration air in air intake duct on the air intake duct region of sealing may reduce or make completelyThe positive effect of the best intake manifold length of adjusting is all gone in theory.
Except by prior art be above well-known, have by the first and second pipe configuration componentsOutside the scheme that the straight length of the air intake duct that axial relative displacement respect to one another causes changes, pass throughThe scheme that the respect to one another relative rotation of suction conduit assembly can change effective admission length of tube is also manyKnown.
But rotate the pipe assembly that can reverse relative to each other equally in variable situation at intake manifold lengthLink position on there is sealing problem. In addition, the relative rotation of pipe assembly or pipe configuration component is ledCause the variation of air flow path, particularly cause relatively the different of this air flow path from each run locationTurning to of degree. This point may cause the air-breathing of rotatable change length in different running statusesDifferent flow loss in pipe.
Summary of the invention
Therefore the object of the invention is to, further develop as follows a kind of such suction device,Prior art improves the sealing on the link position between first and second pipe configuration component relativelyProperty and can effectively utilize as far as possible by suction device of the present invention can be for making in motor vehicle simultaneouslyWith structure space.
According to the present invention, the suction device that this object is addressed type by civilian head is achieved, at thisIn suction device pipe configuration component with the first axial location keep axial spacing away from the second axial positionBe set up there is the second opening and in this suction device suction device there is in addition a provision for sealing, shouldProvision for sealing can it by the closed position of the second closure of openings with can by suck air from air-breathingIn the external environment condition of pipe, suck between the open position in air intake duct and move by the second opening, make theTwo openings form an interim opening of air intake duct according to the position of provision for sealing.
Common the second opening is positioned at the downstream of the first opening.
By will with the first opening, preferably in downstream, keep the second opening of spacing setting to be arranged on pipeOn configuration component, can change by opening and closing the second opening hydromechanical effective length of air intake ductDegree, and needn't move the pipe configuration component equally with the first opening for this reason. Relative by provision for sealingThe relative motion of pipe configuration component can selectively open or close the second opening, thus can not be asPass through like that in the prior art a telescopic air intake duct, but by sucking with first at oneOn mouthful different axial locations, provide an additional suction inlet to cause the fluid force of air intake duct length temporarilyThe Significant Change of learning.
In addition, due to according to the present invention select, by the second opening selectively opening and closingThe reason of the length variation of the air intake duct causing, and rotate at need in the situation that the length that causes changes notWith can avoid the different of the air that sucks in the different run location of adjustable length air intake ductMovement-oriented.
Provision for sealing can be equipment arbitrarily in principle, for example one swingable renovate or one canStraight-line dividing plate. For example provision for sealing can be by lifting door to open from pipe configuration componentWith on pipe configuration component, close the second opening by same door is placed on. Wherein lift motion andPlacing motion can be a radial motion based on tubular axis line or the fortune together with radial motion partsMoving.
Can obtain in the following way in small valuably structure space especially reliably andEmbodiment that can excellent sealing: the pipe configuration component with the first and second openings is the first pipe configurationAssembly, and provision for sealing has about the first pipe configuration component and can move coaxially and along tubular axis lineThe second pipe configuration component that ground arranges, this pipe configuration component can be between closed position and open positionMobile, wherein air intake duct comprises the first and second pipe configuration components. Having of two pipe configuration componentsBetween these pipe configuration components along the effect of the coaxial setting of axially the relatively moving property of tubular axis line justTo be the little knot irrelevant with each relative position respect to one another of the first and second pipe configuration componentsConformational space demand. Such the second pipe configuration component can cover the second opening in closed position, andIn open position, do not cover.
For the gap that may need sealing keeps very littlely, preferably the second pipe configuration component movablyBe arranged on the first pipe configuration component.
For example can axially, move relative to each other along common tubular axis line by thering are two belowPreferred embodiment the present invention being illustrated of pipe configuration component. Therefore the pipe that civilian head addresses is joinedPut assembly and be called all the time hereinafter " the first pipe configuration component ". But should give much attention to simultaneouslyBe: replace relative to the first pipe configuration component and can axially between open position and closed position, moveThe second pipe configuration component can arrange the envelope that can move between open position and closed position arbitrarilyHull closure.
In the length of correspondingly selecting the second pipe configuration component compared with the length of the first pipe configuration componentTime, can change thus the hydromechanical effective length of the air intake duct of suction device of the present invention, andNeed not change generally size air intake duct or suction device for this reason. Therefore can be than in prior artIn more effectively make full use of structure space.
Although the second pipe configuration component can axially exceed the first pipe and join in its one of run locationPut assembly and stretch out, in the suction device of the present invention that makes to discuss herein, also can join according to the second pipeThe run location of putting relative the first pipe configuration component of assembly changes the structural overall length of air intake duct slightlyDegree. But preferably only change by the relative displacement of relative the first pipe configuration component of the second pipe configuration componentThe hydromechanical effective length of air intake duct, the structural length of air intake duct is not joined by the second pipePut the impact of the position of assembly.
Can consider in principle: according to making with the revolution of the coefficient explosive motor of suction deviceTwo pipe configuration components move continuously between open position and closed position. Result is then: secondThe aperture area of opening can be according to the run location of relative the first pipe configuration component of the second pipe configuration componentChange. But in order to realize the good as far as possible of link position between first and second pipe configuration componentSealing preferred: the second pipe configuration component can without centre position ground can only open position with closeBetween position, move. Relative the first pipe configuration component of the second pipe configuration component preferably only has two not thusContinuous run location, i.e. open position and closed position. This point allows to join at first and second pipePut between assembly seal is only so set, they ought be positioned at close stance by the second pipe configuration componentPut when middle effective. With in the prior art well-known that can continuous linear move, in whole movementOn stroke, require the pipe configuration component difference of the sealing between first and second pipe configuration component, the present inventionThe air intake duct of suction device need to be beyond the described relative position effective seal. Then,When the second pipe configuration component is only opened the second opening for through-flow in open position, and without sealingWhen the first opening, in the situation that moves into the second pipe configuration component in open position, infiltrate air basicOn can not enter.
Therefore preferably the second pipe configuration component for through-flow second opening of opening in its open position,And without partially or even wholly sealing the first opening.
Preferred for the above reasons: only in the closed position of the second pipe configuration component, to implement being present inThe sealing in gap, particularly annular gap between first and second pipe configuration component.
Preferred seal is arranged on the first pipe configuration component and remains there, thereby the second pipe configurationAssembly also relatively seal move axially. But this point nonessential like this.
Preferably the second pipe configuration component one at the second pipe configuration component from closed position to open positionSliding motion time in axial seal region above, have with another when the described sliding motionIn the different size of axial seal region below. Can realize in this way: in aboveAxial seal region in the time of the sliding motion from closed position to open position as early as possible from oneHave in the contact point that is arranged on the sealing section on the first pipe configuration component and depart from and the second pipe configurationAssembly in axial region below due to it different sizes can be attached in aboveThe situation of seal touchless of sealing area under move. Equally in axial seal region belowIn the time of the displacement from closed position to open position, can depart from as early as possible at the first pipe configuration componentOn be attached to its sealing section.
Result is thus likely: only have the closed position or that is arranged in it when the second pipe configuration componentIndividual apart from the very near axial location in this closed position time, on the first or second pipe configuration component axiallyThen the sealing that is arranged on the both sides of the second opening is just touched with each other pipe configuration component. Result is,Not only can in closed position, realize good sealing effectiveness, but also can realize the sealing of participationVery high service life.
In order further to protect the seal being arranged between first and second pipe configuration component preferred: theRelative the first pipe configuration component of two pipe configuration components is not arranged on this pipe configuration component revolvably.Can on the first pipe configuration component, axial guides be set, these axial guides and the second pipe for this reasonCooperation axial guides acting in conjunction as follows, the particularly shape acting in conjunction in locking manner of configuration component,Allow the axial relative motion of the first pipe configuration component and the second pipe configuration component, and prevent along circleZhou Fangxiang is around the relative motion of common tubular axis line.
Within the second pipe configuration component can radially be arranged on the first pipe configuration component in principle or radiallyBe arranged on outside the first pipe configuration component. But in order to provide the second pipe configuration component relative the first pipeConfiguration component drives with the motion connecting of the second pipe configuration component with relative its, for fear of the first pipeThe fault of configuration component is preferred: the second pipe configuration component surrounds the first pipe configuration component at radially outer.
So situation of the different closure size of preferred above-mentioned the second pipe configuration component as follows: inThe clear span of sealing section is above less than the clear span in sealing section below.
Preferred in order as far as possible effectively to make full use of in motor vehicle existing structure space: the first pipe is joinedPut assembly by the second pipe configuration component in the time that the latter is arranged in closed position then axially at least firstOne side of opening exceeds, and preferably axially exceeds in both sides.
As optional or preferably as a supplement, can specify for the same reason: the first pipe configuration groupPart by the second pipe configuration component in the time that the latter is arranged in open position then axially at least at the first openingA side exceed, preferably axially exceed in both sides. Although the first opening can be by the first pipe configuration groupThe otch of a window-like in the wall of part forms, but preferably specifies: the first opening is joined by the first pipeThe longitudinal end of putting assembly forms. In order to import air or to be along the direction of tubular axis line more easilyBurner oil more easily, the longitudinal end with the first opening of the first pipe configuration component is passableTowards the axial direction funnel-form of longitudinal end expand.
According to the present invention, when the second opening moves into opening of it for through-flow by the second pipe configuration componentWhen open position, do not need then to seal the first opening.
Therefore the lasting opening that preferably the first opening is air intake duct, can be with air-breathing by this lasting openingThe external environment condition of pipe be starting point and the second pipe configuration component reach air intake duct location-independently. ThisPoint has ensured: even move in malfunctioning situation at the second pipe configuration component, although be no longer variousWith revolution optimization, but can be still with the coefficient explosive motor of suction device fullySupply air.
Preferably the second open construction becomes annular, surrounding tube axis in the wall of the first pipe configuration componentOpening, wherein the second opening can axially pass through joint pin cross-over connection, for one side can be the first pipeEach axial length unit of configuration component provides the large as far as possible aperture area of the second opening and anotherAspect can provide the first pipe configuration component of stable as far as possible and rigidity.
In order to simplify processing and assembling, the first pipe configuration component can be configured to be made up of many parts,For example have the first axial part section, this axial part section has one with the first and second openings and bandHave the pipeline section of a connected structure (Fuegeformation), and have the second axial part section, this is axialPortion's section has a pipe fitting and a corresponding connected structure (Gegenfuegeformation), and wherein twoIndividual axial part section can be assembled into the first pipe configuration group by connected structure and the joint of corresponding connected structurePart.
The joint pin of described axial leap the second opening can axially exceed the second opening and extend or/and canAxially-movable guiding for the second pipe configuration component on the first pipe configuration component. The second pipe configurationAssembly can have corresponding axial groove, preferably radially outward stretches out and is configured in the first pipe configuration componentOn joint pin shape insert in locking manner in these axial grooves. Then joint pin can be aforementioned axis guideTo part, axial groove is described cooperation axial guides.
The second opening can be limited by the first pipe configuration component in axial both sides thus, and this makes to form hasThe first pipe configuration component of axial length becomes possibility arbitrarily.
For regulating the second pipe configuration component, relative the first pipe configuration component can specify: suction device bagDraw together an actuator, this actuator transmits force and motion ground with the second pipe configuration component and connects.
As being well-known, useful by prior art: according to air inlet pipe routineThe revolution of the coefficient explosive motor in ground changes the hydromechanical effective length of air inlet pipe. ForThis object suction device can comprise a control device, this control device be configured for according toThe suction device routinely revolution of coefficient explosive motor makes the second pipe configuration component at close stancePut between open position and move.
Conventionally suction device has multiple air intake ducts, for example, as sent out with the coefficient internal combustion of suction deviceThe air intake duct of the cylinder as much that motivation has. In possible situation, suction device has multipleThe air intake duct that forms or further develop according to above-mentioned viewpoint is useful: each the of multiple air intake ductsTwo pipe configuration components link up for the common movement between closed position and open position. ThisA bit first make to become and may make the second pipe with next for multiple air intake ducts arrange a common actuatorConfiguration component becomes possibility relative to synchronous as far as possible the moving of each the first pipe configuration component, and this valuablyThe unified inlet air conditions of each cylinder of explosive motor is provided.
For the noise emission that reduces suction device of the present invention can specify: the first pipe configuration component eachIndividual the first opening is positioned at the resonance volume being surrounded by resonance housing.
The noise emission that wherein may come from suction device for further minimizing can specify: resonance holdsLong-pending can be by opening part and closure member, be for example divided into the son of sealing respectively by renovating of can regulatingResonance volume, wherein at least one has its first opening, preferably has its first and second openingThe first pipe configuration component is arranged in every sub-resonance volume.
In addition, the present invention relates to a kind of explosive motor, it has one as explanation and useful in the aboveThe suction device that further develops.
Brief description of the drawings
To the present invention be described in further detail by accompanying drawing below. In accompanying drawing:
Fig. 1 be suction device of the present invention longitudinal section and
Fig. 2 is the cutaway view of suction device illustrated in fig. 1 along the section II-II of Fig. 1.
Detailed description of the invention
Shown in Fig. 1 and 2, it is being the enforcement side of the present invention that is generally referenced as 10 suction deviceFormula.
This suction device comprises two air intake ducts 12 and 14, and these air intake ducts are respectively along tubular axis lineRA12 and RA14 extend. Air intake duct 12 surrounds with air intake duct 14 air intake duct 13 by air intake duct 15Surround.
Because two air intake ducts 12 and 14 are configured to substantially flat about a drawing perpendicular to Fig. 1Face with relatively tubular axis line RA12 is parallel with RA14 and equidistant plane of symmetry Mirror Symmetry, underFace represent two air intake ducts 12 and 14 only in Fig. 1 and 2 respectively the air intake duct 12 in left side enterRow explanation. The explanation of air intake duct 12 is equally applicable under necessary correction to air intake duct 14.
Air intake duct 12 comprises the first pipe configuration component 16, and this pipe configuration component is in shown exampleComprise the first axial part section 16a and the second axial part section 16b. The second axial part section 16b with same be inhaleThe corresponding second axial part section structure all-in-one-piece of the first pipe configuration component of tracheae 14. But this alsoNonessential like this.
The first axial part section 16a and therefore the first pipe configuration component 16 are in their preferred funnel shaped suctionEnter on longitudinal end (Ansauglaengsende) 18 and comprise the first opening 20, this opening is as continuingOpening is open all the time. Can carry out fuel oil injection by the first opening 20. Axially along tubular axis lineRA12 goes downstream and keeps spacing with the first opening 20 be configured with second on the first pipe configuration componentOpening 22, this opening is configured to surrounding tube axis RA12 substantially in shown example, exceptOutside joint pin 24, these joint pins will be positioned at the first pipe configuration group of that side of the second opening 22The connected structure 26 of the first axial part section 16a of part 16 be axially positioned at this of the second opening 22The first axial part section 16a of side and therefore the body 28 of the first pipe configuration component 16 preferably connect intoOne.
The connected structure 26 of the first axial part section 16a of the first pipe configuration component 16 is illustrating at presentIn example by with the corresponding connected structure 30 of the second axial part section 16b of the first pipe configuration component 16Connection for the first and second axial part section 16a and 16b are connected into the first pipe configuration component 16.Connected structure 26 and corresponding connected structure 30 mutually bonding, supersonic welding are connected together etc. ExcellentSelect the first and second axial part section 16a or the 16b of the first pipe configuration component 16 to be made by compatible plastics,Thereby both can make one and bondingly also can make thermal bonding and connect, as be welded to connect.
The second opening 22 shown in Figure 1 is sealed by a provision for sealing 32. Preferred form is relativeAbout tubular axis line RA12 coaxially, preferably radial outside arranges around ground the first pipe configuration component 16Therefore the provision for sealing 32 of the second pipe configuration component 34 is arranged in its closed position, at this close stancePut and prevent that the air sucking from entering in air intake duct 13 by the second opening 22.
Form is that the provision for sealing 32 of the second pipe configuration component 34 can be on the first pipe configuration component 16Along tubular axis line, RA12 is directed movably. In Fig. 1, the second pipe configuration component 34 can thusShift to funnel shaped suction longitudinal end 18 and enter open position, at this open position split shed 22 notSealed by the second pipe configuration component 34 again, thereby can the air sucking be inhaled by the second opening 22Enter in air intake duct 13. Therefore with the state phase of the second opening sealing by the second pipe configuration component 34Than the effective length of hydromechanics that has shortened air intake duct 12. Because when 34 of the second pipe configuration componentsIn closed position shown in Figure 1 time, can only be by the first opening 20 by the air intake suckingIn air intake duct 13.
The second pipe configuration component 34 can be at its second axle that more approaches the first pipe configuration component 16There is a hermetically-sealed construction (Dichtungsausbildung) 36, example to the longitudinal end place of the section 16b of portionAs the seal convexity of a radial protrusion, utilize sealing projection can increase the use of this longitudinal endBinding face on the mating surface 38 that abuts in the second axial part section 16b, does to improve like this sealingWith passing through one in the second pipe configuration component 34 and the first pipe configuration group with minimizing or eliminating infiltration airThe gap forming between the second axial part section 16b of part 16 enters.
As a supplement or optional, can be between first and second pipe configuration component 16 or 34 andOn the first pipe configuration component 16, particularly at the second axial part section 16b of the first pipe configuration component 16On arrange one for seal clearance, the particularly seal of annular gap.
As can be clearly found out in Fig. 2, joint pin 24 can be configured to based on tubular axis lineRA12 radially outward projection and thus can as the second pipe configuration component 34 along tubular axis lineThe motion guide of RA12 prevents relative the first pipe configuration component of the second pipe configuration component 34 with being used as16 around the counterrotating anti-rotation device of tubular axis line RA12. The second pipe configuration component 34 can be for this reasonThere is corresponding groove 40, the appearance of the relative first pipe configuration component 16 of joint pin 24 in these groovesThe radially-protruding radial protrusion part of face is directed to.
In shown example, be provided with four joint pins 24, these for each air intake duct 12 or 14Joint pin also with oppose the second pipe configuration component 34 longitudinally guidings and prevent its relative first pipe configureThe longitudinally guiding part that assembly 16 rotates and relative prevention part (Relativverhinderungsmittel). SoAnd the quantity of joint pin 24 on an air intake duct is not restricted to four, in fact also can arrange fewIn four or more than four joint pins.
Joint pin 24 can be configured with the groove radially inwardly sinking to equally, the second pipe configuration component 34The guide frame shape of radially inwardly stretching out is inserted in these grooves in locking manner. But this is on mounting technologyNot too favourable.
The second pipe configuration component 34 can have one or more draw bails 44 (in shown realityIn example, be two draw bail 44a and 44b), these draw bails can for an actuatorThe interlocking of 46 transmission force and motion, described actuator can be arranged for along tubular axis line RA12Between closed position and open position, relative the first pipe configuration component 36 regulates the second pipe configuration component34。
In shown example, actuator 46 is leverages, and this leverage is not by oneThe control device that illustrates drive for: when sending out with coefficient, the unshowned internal combustion of suction device 10The revolution of motivation drops to a limit revolution of cutting out determining in advance and then utilizes the second pipe to join when followingPut assembly 34 the second opening 22 is sealed, and determine in advance when the revolution of explosive motor rises to oneFixed open that then limit revolution is opened the second opening 22 when above and by the second pipe configuration component 34Adjust in its unshowned open position. As long as the revolution of explosive motor is positioned at and mentions at firstClose below limit revolution, the second pipe configuration component 34 is just retained in closed position neutralization as long as internal combustion is sent outMore than what motivation was mentioned in next open limit revolution, the second pipe configuration component 34 is just retained in itsIn open position. Close limit revolution and open limit revolution and can differ from one another (hysteresis), so thatAvoid relative the first pipe configuration component 16 in the range of revolution that approaches limit revolution of explosive motorTo the vibration operation of the second pipe configuration component 34.
The leverage of actuator 46 can rotate around a rotating shaft 48, makes at actuator 46With interface place draw bail 44a and 44b, that be provided with enough gaps for this reason by this actuator 46Gyration be converted to the straight line sliding motion of the second pipe configuration component 34 along tubular axis line RA12.
Actuator 46 can have portion's section 45 of a dual U-shaped, the each U-shaped branch section in them45a and 45b surround respectively an air intake duct 12 or 14, preferably around live along hemicycle. EachOn the end regions of the section 45a of U-shaped branch and 45b, can arrange respectively one for each U-shaped is dividedThe section 45a of portion, 45b can be connected in the draw bail (ginseng on the air intake duct 12 or 14 of attaching troops to a unit with the relative rotationSee draw bail 44a and 44b on the section 45a of U-shaped branch for example). In shown example, encloseAround one perpendicular to tubular axis line RA12, RA14's and be parallel to the relative rotation axi RV of rotating shaft 48Relatively rotate.
For provision for sealing 32 or the second pipe configuration component 34 air intake duct 12 and 14, that arrangeSynchronous as far as possible motion, preferably two the second pipe configuration components of air intake duct 12 and 14 are common with oneWith actuator 46 connect, make two the second pipe configuration components of two air intake ducts 12 and 14 can onlyJointly between closed position and open position, move.
As can be clearly found out in Fig. 1, the first pipe configuration component 16 and its run location-open position or closed position-independently axially exceed the second pipe configuration component towards both direction34, thereby the structure length L of pipe the configuration component 12 and 14 second pipe configuration component of respectively not attached troops to a unitThe impact of run location. Thus can be by regulating the second pipe in the situation that structure length L is constantConfiguration component 34 changes the effective length of the hydromechanics of air intake duct 12 and 14.
