Description
The present invention relates to a kind of supplementary equipment driving mechanism and a kind of supplementary equipment that is used for to engage having of motor car engine with the belt wheel that separates.The present invention relates to a kind of like this driving mechanism or rather, wherein belt wheel is set up the transmission of torque connection of belt-guiding device to axle by friction clutch under jointing state, and can be under separated state around the supporting of axle coaxial rotation ground, wherein friction clutch is made usually thus, the active friction transmission part of belt wheel can be guided with moving axially, and for engaging on the corresponding passive friction transmission part that is pressed on axle.The present invention relates to a kind ofly like this have apparatus casing, axle aspect the supplementary equipment, be arranged in the equipment application mechanism on the axle and the supplementary equipment of the belt wheel rotatably supported, this belt wheel can close or separate with being coupling by means of clutch.
Disclose a kind of supplementary equipment driving mechanism in EP 0 136 384 A2, it intervenes the rotation of engine crankshaft by means of belt.On the bent axle of motor belt wheel is arranged, it is by a plurality of supplementary equipment of the same driving of belt.In this structure, drive servo steering mechanism as water pump, refrigeration compressor, air pump, generator and the automobile of supplementary equipment.This supplementary equipment needn't just drive when engine start together thus, but the belt wheel on the bent axle has the clutch that TURP changes, and the member that for this reason needs is arranged in belt wheel inside and part is arranged on the axle.In case engine start, supplementary equipment is just connected.But the structure of this belt wheel is quite complicated, and clutch mechanism is also very expensive accordingly.
EP 0 416 492 B1 have described a kind of stepless speed variator with belt wheel that can stepless adjustment.Under the situation of this belt wheel, on the sleeve sections that axially stretches out, be provided with spline, it can engage with the internal splines of sleeve and separate by moving axially of sleeve.But this engaging process can only under static state carry out.
DE 42 43 777 A1 have proposed a kind of supplementary equipment driving mechanism, wherein belt wheel and be fixed on the movably counterpart that the frictional engagement between the torque plate on the equipment axis connects by clutch housing and realize.This counterpart that movably has axial tooth portion is arranged according to the rotation of belt wheel, but can not relied on belt shaft to supporting movably.Movably construct a circular groove between corresponding wheel and the belt wheel, in this groove, locating the torque plate of axle.Be incorporated on the belt wheel in order to make to be coupling, this movably counterpart compress towards the direction of belt wheel, Zhou torque plate is clamped in the groove that narrows down between these two elements thus, and plays the effect that transmission of torque connects.In the deceleration gear, drive the belt wheel rotation at the state lower shaft that separates.
Other supplementary equipment clutch proposes in DE 195 29 073 C1, DE 10,155 458 A1, US 2 107 341 and DE 196 41 507 C1 with relevant scheme.
Task of the present invention is to improve supplementary equipment driving mechanism and driven supplementary equipment, make its can be littler, lighter, cost is cheaper and mechanically simpler.
According to a first aspect of the invention, solved this task by this supplementary equipment driving mechanism, wherein initiatively friction transmission part move axially relevant the moving axially that causes belt-guiding device.
This solution has guaranteed the changeable property of belt wheel at run duration with simple especially mechanism, thereby for example makes the starting process of internal-combustion engine no longer bear additional moment of torsion resistance.Also smaller for making this friction clutch switch desired stroke in addition, thus can realize handoff procedure fast.Particularly shorter owing to desired switching stroke, relevant the moving axially also and can correspondingly construct shortlyer of belt-guiding device.Urgent move or that belt is dangerous is stranded or reverse that needn't worry belt thus.The jointing state of supplementary equipment driving mechanism inside also can simply be read by the position of belt-guiding device from the outside in addition.
The aspect mentioned according to the present invention of all these advantages can realize by simple mechanical structure in addition, and to change clutch different with TURP thus, this scheme also can be arranged on supplementary equipment originally on one's body.Under any circumstance, initiatively the friction between friction transmission part and the passive friction transmission part connects as the mechanical torque transfer unit between belt wheel and the axle.
Put it briefly, friction clutch needn't only guarantee transmission of torque by friction.Or rather in the mode of execution of most of friction clutches, when active and passive friction transmission part joint, also can cause small at least crooked and/or wedging, friction clutch on the application's meaning is characterised in that, the transmission of torque connection can not risen extremely discontinuously when the active friction transmission part is guided on passive friction transmission part, but rises continuously or with a plurality of steps.This is supplementary equipment is protected whole parts as far as possible and can be worked enduringly thus when driving moment engages a important prerequisite.Do not rely on this when realizing that on the one hand handoff procedure also can be realized very apace when wishing to realize on the other hand.As long as friction clutch can engage suddenly and lock where necessary.
Belt-guiding device is meant and itself holds belt, and those members of particularly axially guiding.Here normally multiple-grooved belt or simple wedge shape belt of the belt of Kao Lving, corresponding thus belt-guiding device comprises complementary multiple-grooved profile or simple V-type face.
Initiatively the difference between friction transmission part and the passive friction transmission part is, has only a motion in the driving component of two phase mutual friction interconnect functions, so that engage and separated state between switch, perhaps at least one more manys than passive driving component motion or obviously more or direct drivings active strigil engages or separates in these two driving components for this reason.In order to keep simple in structure as far as possible, when passive friction transmission part axial restraint, be favourable.
It is accurate mechanically actuated that the active friction transmission part " compresses " on passive friction transmission part, and it makes at least basically, and the friction connection also makes the supplementary equipment drive mechanism engages thus between the driving component.The moment of transmitting when transmission of torque connects between two friction transmission parts is in most of the cases reasonably directly depending on this Operational Limits in Operational Limits such as the impacting force at least.
As mentioned above, initiatively friction transmission part moves axially along axle, to realize that friction clutch connects and to realize thus engaging.The aspect that proposes according to the present invention, belt-guiding device also moves axially with respect to axle when the active friction transmission part moves.
The preferred initiatively friction transmission part of regulating like this, make its for passive friction transmission part engage or to the restoring force of mobile generation or the back edge of passive friction transmission part.This restoring force for example provides by spring assembly, in case initiatively driving component moves to passive friction transmission part from zero-bit, this spring assembly just applies axial force on the active friction transmission part, wherein in not friction connection between the friction transmission part on the zero-bit.Back edge for example can be realized thus by the favourable supporting of active friction transmission part, makes that initiatively friction transmission part must overcome confining force for move axially at first at every turn.This can use simple mechanism by active friction transmission part clamping engagement a little or the slip surface realization that has bigger static friction by other material with respect to driving component.The advantage of these two mechanisms is, is used for operated clutch, just activates or open the energy of frictional engagement as long as consume under the situation of suitable moulding.Thereby making whole clutch configuration be embodied as the Purely mechanical structure, this under the state that engages or separate, needn't keep the easier realization of this state by consumed energy.
Scheme or additional aspects as an alternative, the present invention proposes according to a further aspect, can engage with low cost and simple in order to be used in having of motor car engine with the supplementary equipment driving mechanism of the belt wheel that separates, belt-guiding device can not rely on axle under separated state rotation can be rotated to support on the axle, wherein belt wheel is set up the transmission of torque connection of belt-guiding device to axle by friction clutch under jointing state, and can pivotally support under separated state.
DE 42 43 777 A1 have the stable carrying device in load gear and the deceleration gear between belt-guiding device and axle.But understanding according to a second aspect of the invention, the carrying device of the gear that slows down in many cases is unnecessary.Usually between the state that engages fully and separate fully, can switch just enough.Because also can overcoming inertia in the enough short time, short switching stroke, supplementary equipment quicken.Show that also the contact wear between two friction transmission parts when moving together on two surfaces still is the contact wear of static passive driving component surface when moving together in the time of needn't being significantly less than active driving component surface with the load speed rotation with beginning.
Propose according to the 3rd aspect of the present invention, initiatively friction transmission part is arranged in a side of passive friction transmission part, and the friction connection is only carried out between active friction transmission part and passive friction transmission part.
This inventive concept has particularly realized getting supplementary equipment driving mechanism axial structure very short.Passive friction transmission part for example can be the axle end face on torque plate.This mechanism can be placed in the axial space fully in the layout of a side by whole friction clutch mechanism.The weak point that can construct as far as possible of axle thus, and however other member of supplementary equipment driving mechanism needn't be set on the needed length of axle.
By supplementary equipment driving mechanism of the present invention a kind of preferred embodiment in, be connected the belt-guiding device axial restraint active friction transmission part on.This point is as long as carry out like this, and soon belt-guiding device constitutes with active friction transmission part one, for example constitutes by belt-guiding device and active friction transmission part one on belt wheel.In this case, belt-guiding device and active friction transmission part have constituted the very important element of belt wheel.Axial restraint connects can cancel those driving mechanisms.Self-evident, the scheme cost of one is cheap especially and mechanically simple.The supplementary equipment driving mechanism is not only with low cost on the whole thus, but also very wear-resisting.
For with the supplementary equipment driving mechanism or be that its critical elements is spatially constructed compactly at least, belt-guiding device can be arranged near the radial outside of active friction transmission part.In addition in this case initiatively friction transmission part can be placed in the radially free space of belt-guiding device inside, when operation, be placed in thus around the belt inboard.Can make full use of best thus around the free space of belt inboard, this free space was exactly the dead band for the miscellaneous equipment in the automobile drive mechanism originally.
This layout not only can realize on by the supplementary equipment driving mechanism aspect up to the present described of the present invention, and can on the active friction transmission part can be with respect to axle and belt-guiding device or the axially movable supplementary equipment driving mechanism of belt-guiding device body, realize, but wherein the belt-guiding device body, preferably whole belt-guiding device is arranged in the axial side of passive friction transmission part with the active friction transmission part.
According to this viewpoint of the present invention, when the active friction transmission part can move axially with respect to axle and belt-guiding device or belt-guiding device body, the mode of structure of an above-mentioned side at passive friction transmission part also can use.In this organization plan, belt-guiding device does not rely on moving axially of friction transmission part of active and moves.The shortcoming of this structural type is the requirement belt-guiding device and is the structure of two-piece type between the friction transmission part initiatively.But this can tolerate according to application target or also may be favourable, because when the active friction transmission part wore and tore, this friction transmission part can not rely on other member and changes.For the structure of this supplementary equipment driving mechanism, can react flexibly for the material newly developed that is used for friction transmission part, and needn't influence belt-guiding device for this reason in addition.In addition as a supplement or the replacement scheme of above-mentioned advantage, belt-guiding device may be run into bigger belt force, and can not stop initiatively moving axially of friction transmission part thus.This can only realize when axial engagement at least limitedly, and is impossible realize under the situation of monolithic construction.
When passive friction transmission part was arranged on the annular slab of the reinforcing on the axle, the monolithic construction of clutch mechanism can simplified aspect the passive friction transmission part.
Irrelevant with the supplementary equipment driving mechanism according to which aspect structure of the present invention, when the active friction transmission part is bearing in radially inner side, be favourable.Initiatively friction transmission part is the member that huge power and moment is delivered to follower from driving mechanism.Therefore its supporting will be constructed the most accurately and stable.This just requires firm especially bearing.When the active friction transmission part is bearing in radial outside, accordingly must be at the very large housing of its disposed about, this has just unnecessarily strengthened the supplementary equipment driving mechanism.Initiatively friction transmission part makes the capable axle that directly or indirectly outputs to its radially inner side supporting, and this is not dangerous.Reduced the desired excircle of supplementary equipment driving mechanism in addition greatly.
Situation is identical when belt wheel is bearing in radially inner side.
As a supplement or replacement scheme, be used for having of motor car engine and can engage supplementary equipment driving mechanism with the belt wheel that separates, it is set up belt-guiding device by friction clutch and connects to the transmission of torque that is bearing in the axle on the housing under jointing state, and can be under separated state around the supporting of the coaxial rotation of axle, propose, wherein friction clutch is arranged in radially and/or the axially outside of housing.This layout has realized implementing the present invention, only needs original supplementary equipment that just exists or housing are done minimum change.Because the original housing that just passed of corresponding axle so that interact with belt wheel, only need be provided for the supporting of belt wheel in the housing outside basically.The general construction space is minimized, and this illustrated at the dead band in the above.As above-mentioned advantage replenish or as an alternative scheme friction clutch and its parts that move directly can also be activated from the housing outside, on integral arrangement, significantly simplified the integrated of device driver thus.
Axle preferably is bearing in the radially inner side of the axle sleeve of housing, and belt wheel is bearing in the radial outside of axle sleeve.This has significantly simplified layout, because axle sleeve has utilized twice, can avoid unnecessary structure space loss.
Accordingly can be with each assembly of belt wheel, for example friction clutch, belt-guiding device, initiatively friction transmission part or belt wheel body be bearing in radial outside, so that realize above-mentioned advantage when obtaining with whole parts carry in sizes different radially and/or axially as far as possible.
For the active friction transmission part is pressed on the passive friction transmission part, preferably provide a kind of transmission ring that supports backward.The housing of supplementary equipment driving mechanism or corresponding supporting axle just had many rotational symmetric members originally, and therefore ring can be shaped thereon with the space cost of minimum.Automatically guaranteed the radially fixing of clutch drive thus.Only need to consider to be used for the axial force that friction transmission part compresses each other.Be provided with supporting backward for this reason.Self-evident, the bearing that transmission ring supports thereon backward preferably also is rotational symmetric.
The general construction of supplementary equipment driving mechanism obtains simplifying thus once more, promptly owing to the direct integrated of each assembly in monolithic construction also can use such manufacture method, wherein desired assembly just has been shaped when for example making blank by casting method together.
For make the axial rub driving component or-according to concrete structure-whole belt wheel can be easily and wearing and tearing less mobile, with its be arranged in can axially movable bearing on.Because the switching stroke that needs usually is shorter, even must not be provided for the Equilibrator of belt laterally offset in many cases in friction clutch.Can construct whole device so especially, promptly only be not subjected to load, just separated state could be regulated slight tilting.If be used for the tilting balanced controls of belt accordingly but also can be provided with the working life that requires hope.
Regulating mechanism preferably is set is used for axially relatively moving of belt-guiding device, belt wheel and/or active friction transmission part.This regulating mechanism can have the angular surface type tooth portion of band edge face side and the adjustment belt of the regulating device of fixing with complementary angular surface type tooth portion according to a kind of scheme, wherein the tooth portion of angular surface type can so construct, make that by means of the rotation of adjusting ring and regulating device adjusting ring and/or regulating device can move to axial.Rotatablely moving correspondingly converts axial motion to, wherein rotatablely moves and does not rely on the rotation of axle and/or belt-guiding device fully.But by selecting suitable angular surface type tooth portion to cause big power under the sufficient axially movable situation narrow can also the work of structure space.Rotatablely move and for example can introduce by the member of low pressure jar, servomechanism or similar action.Here also can use screw thread adjustment, for example trapezoidal thread.
Particularly advantageous scheme on a kind of structure that is used for realizing axial motion, axially movable bearing is the rolling body bearing that has interior ring and outer shroud and be arranged in the rolling element between it, wherein regulating mechanism has clamp device, and its interior ring that clamps rolling body bearing under jointing state is to be used for the transmission of drive force square.Corresponding power is applied on the interior ring of rolling body bearing, and whole bearing can move with belt-guiding device or active friction transmission part.Can accurately determine the position by interior ring being clamped on the engagement positio.
Clamp device is made of the spring shackle of the both sides of the interior ring that is arranged in rolling bearing in addition.Have many advantages like this.Clamping force can accurately be scheduled to thus on the one hand.There is Vibrant buffer by elastic device on the other hand.This has guaranteed the operation very stably under jointing state of supplementary equipment driving mechanism.Clamp device also can design so in addition, also has certain clamping force under separated state, also can reduce vibration thus in this state.
Special mode of execution for the supplementary equipment driving mechanism of pressing a fourth aspect of the present invention, belt-guiding device body and active friction transmission part are arranged in an axial side of passive friction transmission part, in another embodiment, the active friction transmission part is arranged in the axially extended groove of belt-guiding device body.Groove in the belt-guiding device body is the hole, and initiatively friction transmission part is positioned at wherein, and initiatively friction transmission part passes this groove or stretches out from this groove and compresses passive friction transmission part and engage being used for.By this organization plan for the supporting of belt wheel body itself as long as lower requirement, because bigger axial force can be directly by initiatively friction transmission part transmission.By the driving component device of rotation can be provided to parts in the axially extended groove that the active friction transmission part is arranged in the belt-guiding device body at an easy rate, this driving component device is carry-over moment between active friction transmission part that engages and belt wheel body.
The regulating mechanism that the most important thing is active friction transmission part or belt-guiding device for this organization plan can have elastic clamp device, and this clamp device is clamped between active friction transmission part and the belt-guiding device driving component device to be used for the transmission of drive force square under jointing state.The driving component device has guaranteed to be pressed on the friction surface of passive friction transmission part by spring force thus.Further play the effect of Vibrant buffer thus.
When the active friction transmission part axially passed completely through the belt-guiding device body, axial force transmission loaded especially little for belt-guiding device or belt-guiding device body.In a kind of particularly preferred mode of execution, initiatively friction transmission part has a plurality of discrete friction pieces along circumference for this reason, and when the supplementary equipment drive mechanism engages, the end face of friction piece plays the effect with passive friction transmission part frictional engagement.
In a kind of preferred scheme, belt wheel body and/or initiatively friction transmission part rotatable and can be bearing on the outer circumferential area of supplementary equipment housing with moving axially.The belt wheel body is the whole assembly of supplementary equipment accordingly.Clearly determined it is not driving pulley thus, but the belt wheel of supplementary equipment itself can switch.
The joint that particularly can realize single supplementary equipment thus with separate.This not only makes saves energy during starting process, and can both save energy in automobile drive mechanism whole service process, because supplementary equipment where necessary can be single or be become set of bond and separate.
For a kind of structural simplification, the regulating device of regulating mechanism is the assembly of supplementary equipment housing.Particularly the tooth portion of angular surface type can direct forming on the respective regions of supplementary equipment housing, needn't require the member that adds thus.Here for example also can use plastics technology, thereby for example in the spray process, the tooth portion of angular surface type directly be constituted together.Also can carry out this structure by suitable casting process.
In order in the mode of execution of all these propositions, to realize effective conjugation and to enlarge rubbing surface, according to a kind of mode of execution, initiatively the friction surface on friction transmission part and/or the passive friction transmission part is made of the circular of a plurality of mutual coaxial arrangement or the ring segment-shaped serrate slot of circle, the friction surface on the wherein passive friction transmission part have with friction transmission part initiatively on the serrate slot of friction surface complementation.These serrate slots are chimeric mutually with its side under jointing state.Structure according to groove cross section and circumference can play the reinforcement pressuring action.Reduced liability fraying owing to enlarged friction surface in addition.
In the cheap especially scheme of a kind of cost, belt wheel body, belt-guiding device and/or active friction transmission part are by the plastic materials manufacturing.Belt wheel body and active friction transmission part can be made in a manufacture process according to hope accordingly by means of general plastic working method, also can be used different materials, for example pass through coinjection moulding at this.Also can use metal or stupalith at this.
In order to improve the working life of torque clutch itself, active and passive friction transmission part can have the friction covering face.This friction covering face is absorbed in the heat that has produced when just having begun to skid in engaging process, improved friction factor significantly.
Advantageously initiatively the serrate slot and/or the complementary serrate slot of friction transmission part or passive friction transmission part are arranged in the friction covering face, and the friction covering face also can extend to its effect in the side regions of serrate slot thus.
When on axle, application mechanism being set, be favourable in addition, in the supplementary equipment housing, rotate in application mechanism under the jointing state according to a kind of scheme.The application mechanism that is driven by belt wheel is located immediately in the supplementary equipment housing accordingly, can obtain the compact structure unit once more thus.At this can be different application mechanisms, and it has constituted rotor with axle, and rotor interacts with apparatus casing in the ordinary course of things.
Apparatus casing is pump case preferably, and application mechanism's pump impeller preferably accordingly.Usually use pump for the supplementary equipment on the internal-combustion engine, for example water pump, air pump, air condition compressor, power assistance pump for steering etc.As long as its correspondence is furnished with switchable belt wheel, it can engage where necessary and separate so.Can significantly reduce the power loss of internal-combustion engine thus.
According to a further aspect in the invention, it relates to a kind of supplementary equipment that is used for motor car engine, and this supplementary equipment has apparatus casing, axle, be arranged in the application mechanism on the axle and can be rotated to support on belt wheel on the excircle of apparatus casing, and belt wheel can close or separates with being coupling by means of clutch.
At first the supplementary equipment according to this scheme directly is provided with the belt wheel that directly is bearing on the apparatus casing, the engaging an of mechanically operable of this belt wheel and supplementary equipment.Particularly can carry out a kind of layout by the mechanically actuated clutch, wherein under switching state-just separate or when engaging, make corresponding actuator, for example motor, servomechanism, magnet or similar means are not subjected to loading, and only need consumed energy in handoff procedure.Explained that it was the structure of saving locational space especially that this belt wheel is positioned at the outer layout of housing.Supplementary equipment can be selected to engage or separate, and belt is chimeric with belt wheel all the time.Therefore motor has only the driving mechanism acting that just needs once more supplementary equipment when supplementary equipment also engages.
Explained that the present invention was that according to its outstanding advantage of many details belt wheel can directly be the assembly of friction clutch.Aspect very important cost in automotive field, the also simpler thus requirement of satisfying operational reliability is because friction clutch is very simple clutch with respect to known electricity or mechanically very complicated mechanism particularly on its function and structure.
Self-evidently for top explanation be, the method that is used for the supplementary equipment driving mechanism of operation of combustion engine also is favourable, wherein this internal-combustion engine has at least one and has and can close supplementary equipment with the belt wheel that separates with being coupling of supplementary equipment, wherein the supplementary equipment driving mechanism is by the belt wheel that is connected with the bent axle of motor car engine and the belt drives chimeric with at least one belt wheel of supplementary equipment, and wherein belt wheel carries out with separating according at least one predetermined parameters and/or according to operator's selection with the joint of the axle of supplementary equipment.A kind of in the particularly previously described organization plan of this supplementary equipment driving mechanism.
Crankshaft pulley can engage or separate in the prior art, and according to this method advantageously, single supplementary equipment can be separated from drive combined unit when not needing this supplementary equipment.This is favourable when using water pump or refrigeration compressor particularly.

On the engaging zones 14 of pump case 2 suit guard ring 23, it has been fixed rolling body bearing 15 and has fixed belt wheel body 16 thus.Between the interior ring 17 of rolling body bearing 15 and guard ring 23, be provided with annular return spring 24.An annular holddown spring 25 is arranged on the opposite side of interior ring 17.On the engagement positio shown in Fig. 1, interior ring 17 is clamped between return spring 24 and the holddown spring 25, thereby interior ring 17 is clamped on the engaging zones 14 reliably and un-rotatably.
Moving axially by means of realizing at the adjustment ring shown in Fig. 2 and 3 of belt wheel 20 adjusted the tooth portion 27 that encircles in that the side towards pump case 2 has angular surface type.Pump case 2 is provided with complementary angular surface type tooth portion in the adjacent adjustment region 28 of itself and engaging zones 14.Adjust ring 26 sides and have regulating lever 29, regulating lever 29 is by hanger 30 operations.This operation realizes by the suitable mechanism on the hanger 30 that acts on regulating lever 29, and this mechanism makes adjustment ring 26 around its axis rotation.
As can directly finding out in this embodiment, frictional engagement is set up thus, initiatively friction transmission part, just belt wheel body 16 is guided movably with the end face axial with serrate slot 22 that it deviates from pump case 2, and to be pressed on corresponding passive friction transmission part in order engaging, just to have on the torque plate 11 of serrate slot 12, wherein initiatively friction transmission part move axially relevant the moving axially that causes the belt-guiding device that constitutes by receiving groove 21 accordingly because it is to constitute one mutually.
The mode of action and working principle to above-mentioned water pump 1 elaborates below.
Under the jointing state shown in Fig. 1, belt wheel body 16 is pressed on the friction covering face with its serrate slot 22, and compresses the serrate slot 12 of torque plate 11 thus.The impacting force that for this reason needs applies by holddown spring 25, and the belt wheel body not only plays belt-guiding device thus, and also plays initiatively friction transmission part simultaneously.This power partly reduces by the camber of spring of return spring 24 again.If for example by low pressure jar, servomechanism or similarly device for example the adjustment power of 5N be applied on the regulating lever 29, so by the length of regulating lever 29 and adjust the tooth portion 27 of ring 26 and this power of helical pitch of the tooth portion of adjustment region 28 will be amplified.The multiplication of two regulating mechanisms is easy to draw overall coefficient 25 thus.The power of the exemplary 5N that provides obtains the axial force of 125N thus under the friction situation in not considering tooth portion.This power deducts the power (for example 25N) of return spring 24, obtains axial pressing force (for example 100N) thus.Profile by friction covering face or rubbing surface (approximately coefficient is 3) can further be amplified this power.
As above mention, move axially by adjusting the rotation realization of ring 26 with respect to adjustment region 28, thereby be bearing in the flat area 31 that the domain 26 is raised in the position shown in Fig. 1 on the flat area of same structure of adjustment region 28, and two members are separated from each other to greatest extent, holddown spring 25 and return spring are pressed together in the mode of the hope of maximum.Produced enough conjugations thus between the friction covering face 13 of the serrate slot 22 of belt wheel body 16 and torque plate 11, this effect is delivered to desirable moment on the torque plate 11 from the belt wheel 20 by belt drives, and is delivered on the axle 4 by torque plate.Water pump vane 8 is driven and carries cooling water in the inside of pump case 2 thus.
When no longer wishing this pump process or when reaching predetermined parameters, adjust ring 26 and turn round 1/8th commentaries on classics again, thereby the tooth portion 27 on the adjustment ring 26 and the tooth portion of the complementation in the adjustment region 28 are chimeric fully, occupied minimum structure height thus jointly, thereby the mode that spring 24 and 25 is wished with minimum is pressed together or even bearing load no longer.In most of the cases, also wish on interior ring 17, to have the clamping force of a minimum.The size of the axial return movement of this belt wheel body 16 (in Fig. 1 to the right) make serrate slot 22 no longer with torque plate 11 on serrate slot 12 chimeric, and carry-over moment no longer.Pump shaft 4 and pump impeller 8 stop then.
In order to realize this process very simply, regulating lever 29 preferably curves crank-like, thereby it can be seen between belt wheel 20 and pump case 2.
It is evident that, by belt-guiding device-by receiving groove 21 implement-and initiatively the Construction integration between the friction transmission part realized the direct coupling of each axial motion of these two elements with its friction surface 22.But in case eliminate coupling, the rotation of belt-guiding device 21 does not rely on the rotation of axle 4 fully.
Not only under jointing state but also under separated state, initiatively friction transmission part be placed in passive friction transmission part-by torque plate 11 implement-an axial side.Friction when supplementary equipment driving mechanism 1 engages only connects at the active friction transmission part and carries out between the passive torque plate 11 of post-reinforcing for this reason.
According to Fig. 4 the second embodiment of the present invention is described in detail below.Use the reference character identical with regard to member identical on the 26S Proteasome Structure and Function with previous embodiment, and can be with reference to the explanation of front.Therefore only study main difference below in great detail.
In this embodiment, belt wheel body 16 can not be bearing on the engaging zones 14 of pump case 2 with moving axially.The interior ring 17 of rolling body bearing 15 leans against on the guard ring 23.Engaging zones 14 is constructed longlyer in this embodiment, because also put clutch disk 32 (perhaps driving component dish) on engaging zones 14.Clutch disk 32 has corresponding intermediate cylindrical hole for this reason.Clutch disk is provided with a plurality of clutch projections 33 that axially extend forward, and extend in its corresponding hole 34 of passing in the belt wheel body 16.At it in the face of on the end face of torque plate 11, clutch projection 33 be respectively equipped with the ring segment-shaped serrate slot 22 of circle '.The bump that is arranged in serrate slot 22 ' next door can embed the serrate slot 12 on the torque plate 11.
Clutch disk 32 is by on the ring 17 in the dish-shaped return spring 24 ' be supported on.Axial rolling body bearing 36 is arranged, its guiding on engaging zones 14 equally on the back side 35 of clutch disk 32.Adjust be provided with between ring 26 and the cod 36 dish type holddown spring 25 '.
Once second embodiment's the mode of action and working principle are simply described below.
The joint of belt wheel 20 and pump shaft 4 realized by adjusting ring 26 with separating with in the past identical, and this adjustments encircles in the corresponding corresponding teeth portion on the zone 28 that is supported on pump case 2.Under the jointing state shown in Fig. 4, adjust ring 26 and zone 28 farthest is separated from each other, thus its camber of spring position of return spring 24 ' and holddown spring 25 ' be positioned at.Be used on the clutch disk 32 by the masterpiece that axial rolling body bearing 36 transmits at this, clutch disk is pressed on the torque plate 11 with the end face of its clutch projection 33, and plays transmission of torque thus.
Rotate to adjust ring 26 in order to separate, thus should adjustments encircle 26 move right and make thus return spring 24 ' with holddown spring 25 ' unloading.Clutch disk 32 and axial rolling body bearing 36 also move right and clutch projection 33 and torque plate 11 disengagements thus.
Mention for integrity, torque plate 11 can be by the plastics manufacturing.Its spray can be fused to axle 4 or with it thus.Friction covering face 13 also can be settled by the plastic working method one.
Can find out directly that in two kinds of embodiments, belt-guiding device (belt wheel body 16 has the excircle of receiving groove 21) can be independent of the rotation of axle 4 and rotate under separated state.Initiatively friction transmission part, just belt wheel body 16 also deviates from end face pump case 2, that have serrate slot 22 with it and is arranged in passive friction transmission part, just has a side of the torque plate 11 of serrate slot 12, and friction only connects and initiatively and between the passive friction transmission part is carrying out.
The friction covering face can be optionally-as shown here-is arranged on torque plate 11 and/or the belt wheel 20.
It only is the example of the supplementary equipment on the internal-combustion engine that the water pump 1 here is construed as.The belt wheel that is bearing on the apparatus casing also can be used for power assistance pump for steering, air condition compressor and similarly application.
