Background technique
This hold down gag or driving mechanism are for example disclosed by EP 0 878 641 A1 or EP 0 980 993 A2.Two pieces of documents disclose a kind of hold down gag in its second embodiment; It applies impacting force according to the torque of the driven cone of the open conical friction ring driving mechanism that transmits, utilize this impacting force with between two cones and two cones through and clamp around the friction ring of initiative taper rotation.In this manner, can guarantee to exist in other cases to creep and produce sufficiently high impacting force under the dangerous higher torque.In addition, EP 0 980993 A2 also disclose a kind of hold down gag in its first embodiment, and its impacting force can be controlled or adjust from the outside through oil hydraulic cylinder.
Yet the defective of these devices is to lay in considerable impacting force, because the hold down gag of pure machinery is difficult to the total Operational Limits that changes is produced reaction, or needs the quite long reaction time because of the hold down gag from external control.Thus; In can only limitedly satisfying desired characteristic mechanical clamping device; Considering provides the deposit that can not directly measure changes in external parameters through machinery, and under the situation by the external control hold down gag, because the quite long reaction time; Deposit must temporarily be provided, so that can deal with torque peak.
Summary of the invention
The objective of the invention is to, a kind of cone-friction gear and a kind of method that is used to make this cone-friction gear operation are provided, be used to bring the advantage of above-mentioned related fields.
As solution; The present invention proposes a kind of cone-friction gear; This cone-friction gear has at least one input component and at least one output member; They compress by means of a hold down gag against each other, it is characterized in that, hold down gag has a kind of running state-impacting force-characteristic curve; This running state-impacting force-characteristic curve G-bar between the state of rest of cone-friction gear and first running state is different from G-bar between first running state and second running state, the running state-impacting force of at least one compressing unit-characteristic slope substantial constant.
The present invention also proposes a kind of method that is used to make the cone-friction gear operation; This cone-friction gear has at least one input component and at least one output member; They compress by means of a hold down gag against each other; It is characterized in that; Hold down gag is with the operation of a kind of running state-impacting force-characteristic curve, and this running state-impacting force-characteristic curve G-bar between the state of rest of cone-friction gear and first running state is different from G-bar between first running state and second running state, and at least one compressing unit is operated with the running state-impacting force-characteristic curve of slope with substantial constant.
In addition; A kind of hold down gag that is used to clamp the driving component of two transmitting torques that roll each other has measures the particularly mechanism of the key character value of transmitting torque; The mechanism that also has the eigenvalue respective pinch power that applies and measured; It is characterized in that hold down gag comprises that at least two branches compress device, wherein two branches reaction time that compressed device in first minute of compressing device compresses second minute of device than two branches to compress the device reaction time short.Equally, solution proposes a kind of transmission device, has two driving components through the transmitting torque of corresponding hold down gag clamping.
Self-evident, advantageously, can comprise that two branches compress the hold down gag of device with this, be used for different length mechanism, driving component wherein is pressed against each other according to certain eigenvalue.In this regard, particularly comprise all kinds of driving mechanisms with the interaction driving component that rubs each other.
The best reaction time that compressed device in first minute is selected and will lack, make its can impact or analogue make a response fast.The device that does not therefore almost have the reaction time of preferably selecting pure machinery to constitute.In this manner, hold down gag can cooperate the vibration of short time rapidly, the slip between the driving component of particularly can avoiding thus rolling mutually.
Particularly can compress device and not adjust, only directly control according to the critical characteristic value to first minute.In this manner, compressed the whole hold down gag of device-therefore also have-can adjust in first minute according to the variation of impacting or the critical characteristic value is almost interrupted or interrupt.For this reason, particularly compressing device in first minute need not be optimized according to the characteristic curve of eigenvalue.Exactly, important be to compress in first minute device can impact or interruption-particularly with quite short reaction time-suitably make a response.
The characteristic curve of whole hold down gag optimization preferably compressed device through second minute and changes; Therefore this device preferably can be optimized at aspect its characteristic curve or the characteristic curve aspect of whole hold down gag, and need not or needn't impact or unexpected interruption make a response at short notice.What have advantage especially is that adjustment compressed device in second minute, thus selectivity characteristic curve as much as possible.Particularly second hold down gag can be controlled through different or various eigenvalues, exactly requirement is separately made a response thus.In addition, divide and to compress device and particularly in its adjustment range, can reduce the reaction time equally generally speaking in optimization aspect the vibration damping.Yet as the by the agency of of front, the really not so key of the latter can be made a response by the quite short reaction time because compressed device in first minute.
Device of the present invention particularly can drop to bottom line with the loss in the corresponding driving mechanism in suitable design proposal.Particularly can consider that optimal design compressed device in first minute from security standpoint or with operational reliability; Can select like this on its characteristic curve and compressed device in second minute, make it consider that Security compensates by rights and compressed the characteristic of device by first minute and move.
Corresponding therewith; Be independent of other characteristics of the present invention, a kind of hold down gag is provided, be used to clamp the driving component of two transmitting torques that roll each other; Have and measure the particularly mechanism of the key character value of transmitting torque; The mechanism that also has the eigenvalue respective pinch power that applies and measured, wherein, hold down gag comprises that at least two branches compress device; And the impacting force that wherein compressed device in first minute and provide is greater than or equal to the impacting force that is provided by whole hold down gag, compresses device in second minute and reduces by compressing the impacting force that device provides in first minute.Corresponding therewith, driving mechanism also is preferably with two driving components through the transmitting torque of this hold down gag clamping.
In this formation, compressing device in first minute can excessively provide required impacting force, thereby can bear the particularly vibration of short time reliablely.Compress device through second minute and can reduce excessive impacting force again, make loss drop to bottom line thus, and do not exist the short time to impact or the not enough danger of using of impacting force during analogue.
Corresponding therewith conduct replenishes or the advantage of replacement is, compressed in second minute device apply with by compressing the opposite power of power that device applies in first minute.In this manner, particularly reduce power and make reliable operation.In addition, in this device, compressed device in first minute and can make full use of its characteristic curve, and if necessary, can with reduce and produce reaction through compressing power that device produces in second minute.
Compressed device in preferably corresponding therewith second minute and partly compensate by first minute and compress the power that device applies, in suitable design proposal, be independent of above-mentioned characteristic and also can produce above-mentioned advantage.
Even only in hold down gag or corresponding driving mechanism, use separately, if hold down gag is optimized in a suitable manner, above-mentioned characteristic also can obviously reduce the wastage.The supporting force that particularly can produce through impacting force, each driving component is bearing on support or the shell drops to bottom line, can obviously avoid loss thus.In this case, in the said apparatus particularly can with for prevent that Operational Limits from can not control or change fast the safe clearance that must have drop to bottom line can make a response rapidly or with enough power deposits because compressed device in first minute.In contrast, during normal operating condition, through compressed in second minute device preferably reduce impacting force or with support or the synthetic clamping force of shell.Can reduce total losses like this, occur at short notice, therefore on total run time, only play inessential effect because impact or only change fast.
Self-evident, can in having the various driving mechanisms of the driving component that rolls each other, use according to hold down gag of the present invention.It is specially adapted to these devices, wherein each driving component in friction connects or friction condition down or impacting force exist when not enough under the danger of slip interact with each other.Particularly can loss be dropped to bottom line through this hold down gag in this device.
In hydraulic system, for example can apply corresponding impacting force through the piston of Electromagnetic Control.This device compact, mechanical structure is simple.
Piston at first can seal overflow-filler port on its stroke.Through this device or method, can guarantee to have enough hydraulic fluids between piston and the hold down gag at any time.If piston is applied power, its effect is with the direction compression of liquid to hold down gag so, produces enough back pressures until this hold down gag.If piston is not applied power, so too much liquid will pass through the hole overflow, and is very few when liquid on the other hand, can pass through this hole from container servicing fluids body.
Hydraulic control also can be selected gear pump.This gear pump cost is quite low, being also advantageous in that in addition, and it can for example apply variable impacting force through changing rotational speed or changing torque in non-maintaining and reliable ground.Particularly gear pump can wherein, preferably provide torque according to electric current by motoring.This point particularly can be accomplished through regulating than the simpler electric current restriction of voltage-regulation on the automobile generally speaking or electric current.On the other hand, particularly has advantage, because can realize more simply in digital control voltage-regulation down.In this manner, can be simply and impacting force is provided reliably, wherein, even make the pump impeller of gear pump closely and to form consciously, can slide fully.Particularly in the control of regulating torque, for example can guarantee required impacting force through improving rotating speed.
Also can use other pumps to replace gear pump, particularly the sort ofly only provide with the similar pressure gradient of gear pump or have the pump of internal leakage.
Self-evident; The device of the variable impacting force of this generation is independent of other characteristics of hold down gag or driving mechanism; Also can be advantageously used in the step-less adjustment driving mechanism; Especially for conical friction ring driving mechanism, so that guarantee the impacting force that stepless adjustment driving mechanism is best respectively through the bandwidth of adjustment stroke or velocity ratio.
As replenishing or substitute the operation method that proposes a kind of slip gear; This slip gear has at least one input component and at least one output member, and they compress by means of hold down gag against each other; It is characterized in that; Hold down gag is with running state-impacting force-characteristic curve operation, and this indicatrix is different with the G-bar between first running state and second running state at the state of rest and the G-bar between first running state of slip gear.Same as replenishing or substituting; A kind of slip gear that has at least two kinds of running statees is proposed; Wherein, At least one input component compresses by means of the hold down gag that at least one has the impacting force that changes according to current running state with at least one output member against each other, it is characterized in that hold down gag has running state-impacting force-characteristic curve of having introduced the front.By this method or this device, the Economy in the time of can being independent of other characteristics of the present invention and improving the operation of friction ring driving mechanisms.
Particularly this variable characteristic curve of hold down gag has advantage at least one input component rubs interactional all slip gears each other with at least one output member.In the context, notion " friction " comprises two rotations interactions that the sort of non-form fit connects between the driving components, wherein, is preferably in torque when too high, nondestructive slip can occur between two driving components.Particularly this notion also comprises a kind of interaction, promptly between two driving components, passes through static pressure or fluid power or static or electronic or magnetic force generation interaction.Therefore the present invention particularly also comprises slip gear; Wherein, Between mechanical transmissioning piece itself, keep the gap that for example adds as fluids such as gas or liquid; And speed, gap width, pressure and similar parameters are definite like this, make this fluid for example between two driving components, produce interaction through shearing.Thus, this variable characteristic curve also is applicable to the sort of slip gear, wherein, between two driving components, has and facilitates interactional a kind of medium or multiple medium, for example fluid or other driving components.
In all these devices, the interaction between two driving components quite major part is controlled by the power that acts on each self-interaction face of driving component.For example disclosed as EP 0 878 641 A1 or EP 0 980 993 A2, for these two driving components can for example clamp through corresponding bearing by rights.In addition; In those documents shown in each embodiment; Can have hold down gag, they are depending on the variable impacting force that provides under the situation of exporting torque above the regulation base load, thereby when the output torque is higher; Also higher impacting force can be produced, the transferable torque of slip gear can be improved thus.Yet this device causes loss quite high in this slip gear by existing technology, so its Economy is a problem.
As by the agency of, input component does not need directly to be connected with output member, exactly, it is contemplated that driving component in the middle of existing or the friction measure in the middle of connecting, like additional fluid or other interactive mechanisms yet.Because have equilibrium of forces in the driving mechanism, input component and output member also can exchange.Yet, because this driving mechanism usually is in the complicated power train, so must keep this difference generally speaking.Self-evident in addition; As long as at least one component of the degrees of freedom of when clamping or compressing, being utilized is aimed at the interactional surface of corresponding driving component in a suitable manner, two driving components compress against each other also can through these driving components move to degrees of freedom accomplish.
Can and consider under the dissimilar running statees and move under different operation states according to friction ring driving mechanism of the present invention.The running state of these types for example can be input torque or output torque, and rotating speed, power or power distribute, pressure perhaps also has temperature, time etc. and proportional therewith measured value.Run duration at this slip gear; Under various running statees, utilize the running state of current type, wherein-unimportant or proportional according to the running state of practical implementation form or conversion-some types with the running state of the other types that are easy to measure.
As replenishing or selecting, for example can utilize a kind of slip gear to realize variable characteristic curve, wherein, hold down gag comprises at least two compressing units.Through this hold down gag that comprises at least two parts, running state-impacting force-characteristic curve is mode quite simply, as the front is introduced, cooperates desirable requirement.Relevant therewith, between two kinds of running statees or the notion " G-bar " between a kind of running state and a kind of state of rest be a numerical value, it obtains through the G-bar or the average straight line of a differentiate in running state-impacting force-characteristic curve corresponding interval.Through the change of slope, can aspect two, optimize running state-impacting force-characteristic curve at least with operating necessity aspect.Just between two kinds of running statees, manage to produce the ratio of optimizing as far as possible with the driving force aspect that depends on current concrete running state, thereby consider that instantaneous running state as far as possible optimally selects impacting force.Can under the optimization efficiency of slip gear, loss be dropped to bottom line thus.And characteristic cooperation can make direct transformation between this two states between first running state and the state of rest, can base load and basic loss obviously be dropped to bottom line thus.Self-evident in this case, this measure not necessarily produces results of optimization fully, and this point will be decided according to the boundary conditions that exists.Yet the professional workforce can improve the efficient of this slip gear thus.In this case, perhaps the professional workforce need and may increase between the cost in other measures of raising the efficiency and make a choice.
What have advantage especially is, has different operation states-impacting force-characteristic curve as two compressing units of hold down gag constituent element.Through the combination of two specific character curves, the corresponding cooperation of mode that the combined characteristic of hold down gag comes into plain view and can understand.
Best two compressing units produce first component of impacting force separately under first running state; Under second running state, produce second component of impacting force separately; Wherein, the difference between first and second component of first component of first hold down gag and the difference between second component and second hold down gag is different.A kind of system is provided in this manner, and wherein separately compressing unit total impacting force to hold down gag under running state separately provides different component, can mode simple in structure influence the characteristic curve that always compresses device thus.
In this case, be independent of other characteristics of the present invention, two compressing units can be by measuring with running state and/or relevant parallel connection of impacting force or series operation formation.Thus and through velocity ratio suitable under the corresponding connection, the combined characteristic of hold down gag can have no to cooperate existing requirement difficultly.
Though, can in quite wide scope, cooperate the running state-impacting force-characteristic curve of this hold down gag through suitable curvilinear plane or similarly measure.But its defective is generally speaking, like tolerance, and the gap, the external action of thermal expansion or analogue is moved characteristic curve, thus characteristic curve no longer can be exactly according to corresponding running state continuity.Therefore, particularly in this case, can guarantee that no longer the variation of operating conditions also produces the desired variation of impacting force.Be independent of other characteristics of the present invention-proposition now for this reason-also, at least one compressing unit, best two perhaps all running state-impacting force-characteristic the slope of compressing units is constant basically.This device is quite insensitive to tolerance issues or above-mentioned interference; Because in each compressing unit of respective design; External disturbance is unimportant thus; So that the variation of running state produces the identical change of respective pinch power because the constant slope of current characteristic curve is irrelevant with these interference.Thus, have the friction gearing that its combined characteristic is different from the hold down gag of straight line if use, this solution has advantage especially.Here; Notion " constant basically slope " should be regarded as other required precisions in the original tolerance that just exists in the system in other cases and the total power train, thereby uses overall accuracy or the gross tolerance desired strictness of the slope of notion " constant " unlike system.
Preferably compressing unit interconnects, wherein, connection can machinery or fluid power or static pressure mode constitute.This point also is specially adapted to this situation, promptly has independent separately compressing unit on the driving component respectively.Particularly, input side should be taken into account the input load under having the situation of hold down gag or compressing unit; Wherein, This point particularly can realize through the low impacting force that descends in sub load; Can reduce the total losses of friction ring driving mechanism thus, also have advantage thereby hold down gag that this back flow side has or compressing unit are independent of other characteristics of the present invention.
In addition, through being connected of input side compressing unit and outlet side compressing unit, can be in the impacting force under the full load state decline lower part load of optimizing, thus can total load be dropped to bottom line.
Can use the different parameters of current slip gear as the running state type.They can be input torque especially, output torque, total load, already mentioned other parameters in the power of appearance or front.
Have advantage especially be inspection output torque and/or input torque and-words-total load of needing connect and go up direct information that occur or needed power because therefrom can obtain the friction of two driving components.
Corresponding therewith have advantage be; For the G-bar between state of rest and first running state or first running state and second running state is compared; First running state is the minimum torque of estimating under the full load, and second running state is the maximum torque of estimating under the full load.Corresponding therewith, be suitably to confirm characteristic curve, can measure the required impacting force of maximum torque, thereby characteristic curve can be the straight line between these two points accordingly to estimating under the minimum torque estimated under the full load and the full load.
Straight line was introduced as characteristic advantage front in detail.Equally; In state of rest or for making driving mechanism non-slip and/or when not violating the minimum torque of estimating under reliable desired minimum impacting force of startup of card and the full load between the needed impacting force; Straight line can be established, thereby when using the characteristic curve of variable slope not, also the tolerance immunity can be utilized here.Select this characteristic great advantage to be, base load is limited on the essential minimum, thus the relevant therewith efficient that also can optimize this slip gear.
What have advantage is, two compressing units can be aspect its impacting force separately or its to aspect the shared component of the total impacting force of hold down gag through dissimilar running state changes.Therefore relevant therewith, for example aspect input torque or total load, a compressing unit is changing its impacting force aspect the output torque for compressing unit.In this manner, the total characteristic of slip gear can cooperate the requirement of regulation on very big bandwidth, thereby particularly can be optimized aspect its efficient.

Embodiment
The driving mechanism of Fig. 1 comprises an input cone 1 and an output cone 2, and they are interact with each other with known mode own through adjustable friction ring 3.In this case, input cone 1 is connected with transmission shaft 4 useful effects, and output cone 2 is connected with driven shaft 5 useful effects.Cone 1,2 is in this embodiment diametrically through roller bearing 6 supportings.In addition, cone 1,2 clamps through four-point supporting rolling bearing 7A in the axial direction in this embodiment against each other, thereby can apply required clamping force, is delivered on the output cone 2 or opposite the transmission through friction ring 3 from input cone 1 torque thus.The axially mounting of input cone 1 is not shown specifically in the figure, but for example can realize through four-point supporting rolling bearing 7A or through axial cylindrical roller bearing or similar device equally.
In addition, for clamping or, between driven shaft 5 and output cone 2, have a hold down gag 8, and in this embodiment, input shaft 4 being connected with input cone 1 directly for producing required impacting force.Hold down gag 8 can change between output cone 2 and the driven shaft 5 upper bearing (metal) 7A axial distance or-under clamped condition-produce the clamping force of respective change.
Self-evident; What replace bearing 6 and 7A also can be other bearing means, like axial angular contact ball bearing, and axial self-aligning ball bearing; Axial radial ball bearing; Tapered roller bearing or the similarly combination of bearing or several kinds of bearings are so that radially and on the other hand axially fully clamp supporting with cone 1,2 on the one hand.Equally, can use for example static pressure or hydraulic bearing.
Be in operation, friction ring 3 can be by in detail not introducing here but known mode is adjusted, and select the velocity ratio of driving mechanism in this manner.Self-evident, the overall apparatus that is in operation is born maybe can bear different especially torques.Because it is that friction connects that the useful effect between two cones 1,2 connects,, makes thus and produce controllable slip on the friction ring 3 so impacting force is selected on preferably enough highlands.On the other hand, impacting force need not be too high, otherwise can cause base load too strong, can impair the efficient of slip gear on the contrary.For adjusting driving mechanism more easily, slide advantageously that to be controllable slide with being easy to especially, because only need then rotating speed as adjusted value, and corresponding cooperation of impacting force and transmission are passed through in torque.
In order to adjust impacting force by rights, select the impacting force adjustment relevant in the present embodiment, yet as the introduction of back, impacting force can be selected also according to other running statees with torque.As directly seeing, select the output torque as adjusted value for the impacting force adjustment is special from Fig. 1.
In the present embodiment, hold down gag 8 has two adjustment dishes 9,10, and they have the guide rail that is used for spheroid 11, is bearing on the axle 5 through adjustment dish 9 on the one hand, is bearing on the output cone 2 through adjustment dish 10 on the other hand.In this case, adjustment dish 9 or 10 constitutes like this, and the transmission of torque that makes driven cone 2 is delivered on the adjustment dish 9 through spheroid 11 to adjustment dish 10, is delivered to therefrom on the driven shaft 5 again.The guide rail of spheroid 11 constitutes in this case like this, and the torque of raising is rotated two adjustment dishes 9,10 each other, thereby causes spheroid 11 to move along guide rail, and adjustment dish 9 and 10 pressurizeds are separated from each other.In the desirable device of itself fixing, do not move; Torque directly causes the impacting force slope through the slideway that tilts.In this manner, hold down gag 8 produces and the relevant impacting force of output torque.
The advantage of this device is that it has the very short reaction time as mechanical device, particularly can make a response very effectively to the impact in the outlet side power train.
Parallel with spheroid 11, dish 9,10 is through the spring assembly 12 that the gives hold down gag 8 certain base loads extruding that is separated from each other.
By dish 9 with 10 and the characteristic curve of the device that constitutes of spheroid 11 and spring 12 can only be optimized unfortunately limitedly.Thus, characteristic curve has the zone that undue impacting force is provided.The total losses of corresponding driving mechanism obviously increase thus.For this reason, the device of Fig. 1 has the particularly force compensating in sub load zone.In this embodiment, it is accomplished through hydraulic pressure, and method is between dish that is connected with driven shaft 5 and compression plate 10, to produce pressure through hydraulic pressure, forms reaction force with the impacting force that is produced by spheroid.In this manner, through producing reaction forces by parts that are fixedly connected with driven shaft 5 13, the unnecessary or unnecessary impacting force that can compensation hydraulic produces by spheroid 11 and spring 12.Fig. 4 illustrates corresponding situation, and wherein, the thickness of arrow reflects the height of respectively relying on oneself.Therefore compensate the excessive power of spheroid 11 or spring 12 through hydraulic pressure installation 14, thus bearing 6, and 7A does not have unnecessary load.In this case, the external force of arrow 90 expression driven shafts 5, the external force of arrow 91 expression output cones, arrow 92 expression internal force.
In the embodiment show in figure 1, set up hydraulic pressure 14 through the hydraulic tubing 15 that is arranged in the additional shaft 16, additional shaft is fixedly connected with axle 5 through screw 17.In addition, screw 17 sealing filler ports 18, the latter with the interaction of pipeline 19 and side recessed 20 under, be used for the reliable hydraulic chamber of bubble-freely annotating.Axle 16 has hydraulic seal on its end away from transmission shaft 5, thereby hydraulic pressure installation 14 can have no to constitute difficultly or control from the outside with desired mode.
The device of Fig. 1 also has a fixing body 21, and driven cone 2 is through this fixing body radial support.Through this fixing body 21, hold down gag 8 can be installed in the inside of driven cone 2 without a doubt.
The device of Fig. 2 mode of execution basic and Fig. 1 is corresponding, and therefore identical parts adopt identical reference symbol and repeat no more.
Yet in this embodiment; Base load is not the spring through parallel connection; But produce through the spring 22 of connecting with hold down gag 8, spring-loaded is bearing on the four-point supporting rolling bearing 23 on driven shaft 5 in the present embodiment; This bearing transmits the impacting force between adjustment dish 9 and the driven shaft 5 on the one hand thus, on the other hand with respect to the driven cone 3 of driven shaft 5 axially mountings.
Opposite with the hydraulic pressure delivery pipe 24 among Fig. 1 embodiment, this hydraulic pressure delivery pipe 24 therefrom passes, and stretch in the driven cone 2, thereby corresponding Sealing 25 is set directly on the parts 13 that are fixedly connected with driven shaft 5 always, is called respective disc 13 below these parts.Pipeline 26 through having in the hydraulic pressure delivery pipe 24 is exerted pressure, and between respective disc 13 and adjustment dish 10, constitutes hydraulic pressure 14 thus, and it produces reaction force with the impacting force that is applied by spheroid 11, and reduces total impacting force of hold down gag 8 thus.

The slip gear with comprising its characteristic curve shown in Figure 14-22 has an input cone 101 and an output cone 102, and they interact through adjustable friction ring 103.In this case, 105 useful effects are connected input cone 101 with driven shaft with transmission shaft 104 respectively with output cone 102.Cone 101 and 102 supports through roller bearing 106 (only schematically illustrating among Figure 14) in this embodiment diametrically.In addition; In this embodiment, cone 101,102 clamps through axial cylindrical roller bearing 107 in the axial direction against each other; Thereby can apply required impacting force, so that make torque be delivered on the output cone 102 or opposite the transmission from input cone 101 through friction ring 103.
In addition, for clamping or produce required clamping force, between driven shaft 105 and output cone 102, have hold down gag 108, and in this embodiment, input shaft 104 is connected with input cone 101 directly.Hold down gag 108 can change on output cone 102 and the driven shaft 105 axial distance between the roller bearing 107 or-under clamped condition-produce the impacting force of respective change through spring assembly 109.
Self-evident; What replace bearing 106 and 107 also can be other bearing means, like axial angular contact ball bearing, and axial self-aligning ball bearing; Axial radial ball bearing; Tapered roller bearing or the similarly combination of bearing or several kinds of bearings are so that radially and on the other hand axially fully clamp supporting with cone 101,102 on the one hand.Equally, can use for example static pressure or hydraulic bearing.
Be in operation, friction ring 103 can be by in detail not introducing here but known mode is adjusted, and select the velocity ratio of driving mechanism in this manner.Self-evident, the overall apparatus that is in operation is born different especially torques.Because it is that friction connects that the useful effect between two cones 101,102 connects,, makes thus and produce controllable slip on the friction ring 103 so preferably select impacting force like this.On the other hand, impacting force need not be too high, otherwise can cause base load too strong, can impair the efficient of slip gear on the contrary.For this reason, selected a kind of impacting force adjustment of depending on torque in the present embodiment, wherein, impacting force also can be selected according to other running statees.As directly seeing from Figure 14 and 15; For the adjustment impacting force selects the output torque as adjusted value; Wherein, as by embodiment set forth of following introduction, for example the running state as other types such as total load or input torques also can be used.
In the present embodiment, hold down gag 108 comprises two compressing units 110 and 111 parallelly connected and series connection aspect its impacting force effect aspect its torque measurement, and they are respectively through interior spheroid 112 or outer spheroid 113 (referring to Figure 15) expression.Spheroid 112,113 each comfortable cone side or axle side are arranged on operation in the spherical in compression plate 114,115 and 116.In this case, this embodiment's axis side compression dish 114 and 115 relative driven shaft 105 antitorque settings, and the 116 driven relatively cone 102 antitorque settings of cone side compression dish.On the other hand, compression plate 114,115,116 can move axially and are bearing on these assemblies separately through corresponding sliding bearing 117,118,119.
Therefore; Torque is delivered on the compression plate 116 through bearing 119 from driven cone 102, is delivered on the compression plate 114 with bearing 118 through spheroid 112,113 and compression plate 115 therefrom; Be delivered on the driven shaft 105 through bearing 117 from compression plate 114 again; During this period, compression plate 114,115; 116 axially overcome the spring force of spring assembly 109 and towards being bearing in compressing bearing 120 and can move on the driven cone 102 through axial cylindrical roller bearing 121 and shaft bearing plate 122, and in such a way according to producing the impacting force relevant with torque under the situation of curvilinear plane.Therefore Figure 14 and 15 illustrates the setting under the low torque in the top edge zone of hold down gag 108; And the setting under the high torque (HT) is shown in lower area; Wherein, Can find out that in lower area compression plate 116 is close on the convex shoulder 123 of driven cone 102 under high torque (HT), thereby can have no difficulty ground influences overall apparatus according to torque characteristic curve in such a way.
In this case, Figure 16 illustrates the interaction of two compressing units 110 and 111 with planar fashion, wherein, to Figure 14 and 15 in the identical assembly of assembly effect adopt identical reference symbol.As directly seeing, spheroid 112,113 moves in the spherical of different angle β and γ formation.If desired, also can use more complicated face, wherein, particularly preferably be linear face from the reason that for example prevents reliabilities such as gap or thermal effect.Regulation move down or under the torque of regulation, as the bottom of Figure 16 by adjustment stroke V with respect to the device on Figure 16 top illustrate for example, these sphericals produce stroke H1 or H2 respectively, therefrom draw total kilometres G.Through fixation device travel limit H1, thereby total kilometres G is not linear with the relation of adjusting stroke V.
Spherical for example can constitute like this, makes it produce the characteristic curve shown in Figure 17 and 18.Because the parallel connection relevant with torque therefrom forms the characteristic curve shown in Figure 19, wherein, owing to be connected in parallel on the torque addition of torque aspect, because the impacting force that is connected in two compressing units in axial pressing force aspect is identical.Along with arriving convex shoulder 123, only the characteristic curve of external compression unit 111 is to combined characteristic generation effect.
The characteristic curve that Figure 20-21 illustrates other constitutes, and wherein, forms satisfactory especially combined characteristic (Figure 22) through the negative slope in the interior compressing unit.
As directly seeing from Figure 17-22, in the present embodiment, the running state-impacting force of compressing unit-characteristic curve or torque-impacting force-characteristic slope is constant basically.Through using two compressing units,, still can realize cooperating the characteristic curve that requires separately although this slope is constant basically.Also can realize this point thus; I.e. two compressing units 110; 111 produce first component of impacting force separately when first torque; When second torque, produce second component of impacting force separately, wherein, the difference between first and second component of first component of first hold down gag 110 and the difference between second component and second hold down gag 111 is different.
Generally speaking, slip gear moves with dissimilar running state modes by certain operation at interval.Generally be in this case, should have the first definite impacting force, should have higher impacting force in the upper end at this interval in the lower end at this interval to the requirement of impacting force.In order not go wrong aspect the tolerance that possibly exist, preferably, in operation at interval, has the not running state-impacting force of variable slope-characteristic curve between these two points.Under these prerequisites, can change the for example characteristic curve shown in Figure 23 through the hold down gag that only comprises a kind of compressing unit, although operation only is at interval between 50 Ns of rice and the 350 Ns of rice.Yet the consequence of doing like this is to have the base load that obviously lowers efficiency in the system.
This point for example can be resolved through changing slope of a curve by that kind shown in Figure 24.In this case, characteristic curve is preferably in the range of operation between 50 Ns of rice and the 350 Ns of rice has constant basically slope, and impacting force is dropped near 0 N in the state of rest (0 N of rice), particularly below 1 N.In this manner, the base load in the total system obviously reduces, and can improve total efficiency thus.Yet slope of a curve itself is containing tolerance issues in the change compressing unit, and the present invention is able to solve through using at least two compressing units as stated.
The present invention proposes, and preferably particularly such shown in Figure 24 and 25, the slope of running state-impacting force-characteristic curve in certain range of operation (referring to the 50 Niu Mi-350 N rice in Figure 24 or 25) is less than this G-bar below range of operation.Thereby the base load that can reduce total system is thus raised the efficiency.On the other hand, also can imagine setting like this, it is such to let their characteristic curve be similar to characteristic curve shown in Figure 19, adopts the range of operation between 100 Ns of rice and the 350 Ns of rice.This characteristic curve particularly also can be realized through two compressing units under less tolerance sensitivity.
In addition, for the loss in the total system is dropped to bottom line, what have advantage is for example by that kind shown in Figure 25, is depending on second running state, particularly the situation of total load or the input torque low impacting force that descends for example.In this manner, can further improve the efficient of total system.
The latter for example can be guaranteed through the device shown in Figure 26.This device is corresponding with the device shown in Figure 28 and 29 basically, and wherein, cone 101 and 102 except through roller bearing 106 supportings, supports through angular contact ball bearing 124 in this device in the axial direction.
In this embodiment, hold down gag also constitutes through two compressing units 125,126.But with different in Figure 28 and 29 devices be, compressing unit 125 devices are on output cone 102, and another compressing unit 126 is arranged on the input cone 101.In this manner, no matter whole hold down gag is that impacting force can directly measured and convert to input torque or output torque all.Compressing unit 125,126 has the characteristic curve shown in Figure 27 and 28.Form the characteristic curve shown in Figure 29 thus, it basically with output compressing unit 125 characteristic curve corresponding, but than under the low torque according to its load, its characteristic curve is transited into horizontal line.Output compressing unit 125 characteristic slopes are selected in this regard like this, are desirable full load characteristic curve intersections in this characteristic curve and the operation at interval, thereby when the output torque is higher, produce sufficiently high impacting force.In addition, overall apparatus designs like this, when making the full load in the low engine speed range, also can not surpass desirable full load characteristic curve.Under sub load, can surpass desirable full load characteristic curve according to load, thus the total load thus in the further reduction system, the impacting force meeting is too high down although this is in the full load operation.Through being output compressing unit 125 selectivity characteristic slope of a curves, can move the point of intersection of itself and desirable full load characteristic curve, so that in this manner total load is dropped to bottom line.As directly seeing from Figure 29, output compressing unit 125 characteristic slopes can not with desirable full load characteristic slope of a curve in the range of operation select identical because second compressing unit 126 can not be born this effect.
On the other hand, can as by Figure 30 with two compressing units 125 are connected with 126 31 illustrate for example.This device is also corresponding with the device of Figure 28 and 29 or 26 basically, and wherein, the assembly of same function also adopts identical reference character mark.
In this embodiment, compressing unit 125,126 also is separately positioned on the different driving components of slip gear; The situation about in Figure 26 embodiment, being introduced, in this case, compressing unit 125; 126 comprise ball device 127 separately; 128, they are bearing on the compression plate 129,130 of input shaft 104 or output shaft 105 separately.On the other hand, spheroid 128 be bearing in can axially movable compression plate 131 on, but it is antitorque to import cone 101 relatively.This compression plate also uses as the piston of hydraulic pressure feedback means 132 simultaneously, and its hydraulic pressure feedback means 132 has a piston 133, and its side is connected with compression plate 130.In the compressing unit 125 of outlet side, there are not other compression plates, because spheroid 127 is set directly on the driven cone 102 in addition, wherein, correspondingly also can have independent compression plate, be used to accept corresponding curvilinear plane.
Hydraulic pressure feedback means 132 feeds the inside of cone 101,102 through sleeve pipe 134,135; Wherein, replace this hydraulic pressure feedback means 132 and also can have and the corresponding mechanical system 135 of the device of Figure 31, with compressing unit 125; 126 corresponding dishes 136,137 interact.
The characteristic curve of output compressing unit 125 can be accurately selected in this connection along with the slope (referring to for example Figure 25) of idealized characteristic in range of operation.Then this characteristic curve is brought up to desired height through input unit 126.Under the low-load situation, the decline that corresponding therewith appearance is relevant with load, thus as seeing, accomplish the overall apparatus of Figure 25 idealized characteristic basically from Figure 34.
