165 A1 and the A1 of DE 10 2,014 204 286 describe for manufacture for motor actuator or stator it is common existing
Technology.
The content of the invention
A kind of reluctance actuator is developed according to the present invention.The reluctance actuator includes at least one ferromagnetic stator, is used for
The magnet exciting coil that magnetic flux phi is incorporated into stator and the functional element movingly supported relative to stator.Whole electromagnetism
The strong saturation of electromagnetic system of system, particularly kinetochore.Therefore, the inductance L with the coefficient magnet exciting coil of stator depends on
Position p in the functional element and electric current I by magnet exciting coil.
If be powered to magnet exciting coil, then efforts be made so that the maximized power of inductance L can be applied on effect original paper.By
In single reluctance actuator, by magnet exciting coil is powered can by functional element from certain entrance region from around position
pMThe position p of (inductance L is maximized in the position) is transferred to position pMIn.To this alternatively or in combination, functional element
Can be by being powered to magnet exciting coil to position pMDirection is moved, and by reset force, for example by spring force along the opposing party
Moved to from the position.Functional element for example can be supported movingly in one way so that the functional element can be with
Moved in a dimension cathetus.
Reluctance actuator, which also includes at least one voltage source and at least one, to be used to be powered to magnet exciting coil by voltage source
Control element.Control element constitutes bipolar with magnet exciting coil.This is bipolar need not only to include control element and magnet exciting coil, but
Miscellaneous part can also be included, such as one or more self-induction electricity for being used to reduce and/or prevent to produce in magnet exciting coil
The diode of pressure.Therefore, it is bipolar from broadest see be the unit that is made up of actuation means and magnet exciting coil, the magnet exciting coil by
Voltage fed and magnetic flux phi is incorporated into stator.
According to the present invention, capacitor is connected in parallel with bipolar.So design the size of the capacitor so that the capacitor
At least 1/3rd of bipolar its capacitance of charge or discharge can be passed through with least 50Hz frequency f.
Once magnet exciting coil is powered, then reluctance actuator applies for compensating from outside work in active supporting arrangement
Supporting force FLOpposite force FG.Because supporting force FLTypically last for changing, so opposite force FGWith the electricity by magnet exciting coil
Stream I also has to last for tracking.The energy from voltage source is needed in the stage increased by the electric current I of magnet exciting coil.Now
It has realized that capacitor and it is bipolar between energy exchange in terms of two kinds of different aspects for reluctance actuator active prop up
Use in bearing apparatus, here especially in engine mounting device is favourable.
On the one hand, the frequency model in the vibration typically received by engine mounting device is effectively suppressed by capacitor
Enclose, for example 50 to the voltage higher hamonic wave in the scope between about 200Hz and vibration.Thus, reluctance actuator can be
It is more accurate and pass through opposite force F more in time in the frequency rangeGTo the supporting force F of effectLMake a response, i.e. opposite force FG
Time change can preferably reflect supporting force FLTime change.
On the other hand, energy can be saved.Capacitor can be realized, emptying in the electric current I reductions by magnet exciting coil
Not busy energy is at least partly temporarily stored and is re-used in electric current I increases next time.
In addition, whenever to magnet exciting coil energization and supporting force FLFunctional element is set to resist opposite force FGResistance movement when,
Complete to resist opposite force FGActing.Thus, storage can be transferred to the additional energy in capacitor again in active supporting arrangement
Amount.
It is being reclaimed by the temporary transient storage relevant with operating point or say from external movement " harvest " in the capacitor
Energy, on the one hand make by the mean power of voltage source supplies to be reduced to run active supporting arrangement.On the other hand
Also demand peaks are met.As a result, so small mean power and so small peak power is for for example for motor vehicle
Engine mounting device can be with enough so that manipulates driving engine supporting arrangement by engine controller and saves additional
Peripheral control unit be practical.
It is related to this it has realized that the calculating power provided by current engine controller can overcome completely is used for
The additional calculations for manipulating driving engine supporting arrangement expend, and can also realize tool in the case of special difficulty
There is the installation for adding required hardware of larger hull shape and the suitable heat extraction scheme for smaller vehicle.By described in reduction
Demand peaks, can be reduced for manipulating reluctance actuator, the hardware cost for its cooling and for its power electric device.
Be only used for driving engine supporting arrangement additional controller possibility cancel can correspondingly save installing space,
Material cost and the expense laid for other line.In addition, coming typically advantageously, to pass through from the point of view of vehicular manufacturer
As few as possible controller is tackled.Finally, energy in driving engine supporting arrangement save also in fuel consumption and
Thus in CO2Advantageous effect is played in terms of discharge.Finally, capacitor also causes voltage smooth and therefore reduces reluctance actuator
Reaction of the high-current pulse to onboard power system.
Reluctance actuator typically has advantages below in active supporting arrangement：The reluctance actuator is in no permanent magnet
In the case of run, these permanent magnets are generally made up of rare earth and correspondingly cause high material cost.In addition, being actuated by magnetic resistance
The opposite force F that device appliesGAmplitude and frequency adjust with being separated from each other.
It is known to have modern vehicle, in these vehicles, on the one hand on the other hand supplied by battery and by generator
Onboard power system buffered by capacitor, for example by ultracapacitor.The capacitor used for this purpose is not suitable for
" recovery " " harvests " energy in active supporting arrangement in other words, because these capacitors can not especially fill again fast enough
Electricity.The especially ceramic capacitor or thin film capacitor for the energy storing device being suitable in meaning of the present invention, because these are electric
Container is while with small spurious impedance with especially small stray inductance.Both of these case is conducive to quickly recharging.
In addition, small spurious impedance causes, capacitor quick endurably heating especially in the case where frequently recharging very much.
In addition, the capacitor in the big region of buffering onboard power system or the onboard power system is usual from magnet exciting coil too far.Therefore,
The excessively most of of the energy of magnet exciting coil loses in course of conveying.In addition, being hindered just by multiple impedances in onboard power system
The quick conveying of energy is stopped.
Advantageously, the size of such design capacitance device so that the capacitor can be at least with 100Hz and 250Hz scopes
Interior frequency f pass through series circuit charge or discharge its capacitances at least 1/3rd.The capacitor is then excellent within the range
Change ground to coordinate in its temporarily storage and the smooth function of voltage.Worked in the driving engine supporting arrangement for motor vehicle
Supporting force FLFrequency spectrum in the frequency range have king-sized part.
In particularly advantageous configuration, the gate pole being connected with magnet exciting coil of control element is by being antiparallel to
It is connected by the polarizing diode of the sense of current of control element with capacitor.Such diode will not only pass through self-induction
The voltage U export induced in magnet exciting coil, and self-induction is reduced simultaneously.Such as transistor can be with as control element
Be connected in series with magnet exciting coil, and magnet exciting coil can be antiparallel to again by the sense of current of transistor it is polarizing two
Pole pipe is bridged.If during present transistor is by manipulating the state being not turned on being transferred to from conducting state, then self-induction causes
Electrical potential difference, the potential official post diode current flow.Loop current then flows through magnet exciting coil and diode, and the loop current makes excitation wire
The energy dissipation stored in circle is in the impedance of diode.
In particularly advantageous configuration, control element, which is constructed and/or is routed to, to be used for, and is manipulated independently with it
By it is being induced in magnet exciting coil, beyond predetermined threshold value UtVoltage U export in capacitor.The recovery of energy is in other words
" harvest " need not then force the energization with magnet exciting coil consistent in time.Thus, it is possible in terms of time average in capacitor
In store altogether more energy and further reduce active supporting arrangement total power consumption.While induced voltage U's leads
Go out also to protect control element to be influenceed from voltage peak.
In order to which induced voltage U is exported, control element can be bridged for example by diode, and the conducting direction of the diode is
It is antiparallel to the sense of current by control element.The diode can be separated with control element, but it is also possible to which itself is integrated in
In control element.For example, many mos field effect transistor (Metal-Oxide-Semiconductor
Field Effect Transistor, MOSFET) it is included in the protection diode anti-parallel connected between source electrode and drain electrode.
In addition, power MOSFET especially can be used to manipulate induction type load, in these power MOSFET, the np knots that existed originally or
Puncturing for pn-junction is controllably carried out so that transistor is the protection diode of its own.Therefore, control element is advantageously comprised
MOSFET power MOSFET in other words.
In another particularly advantageous configuration of the present invention, bipolar configurations are H bridges, wherein, pass through H bridges and excitation in guiding
At least one control element is connected in each current path of coil.H bridges realize that additional selection is free in terms of path, at this
The voltage or electric current come out from magnet exciting coil can be exported on a little paths.Such voltage or electric current are primarily due to magnet exciting coil
The change being powered due to self-induction in time is produced.But, such as functional element passes through external support power FLThe fortune of realization
Move in the case of without permanent magnet and magnetic flux is also produced in magnet exciting coil by the remanent magnetization of functional element, the magnetic flux
Voltage is produced again.
For example, a leg of H bridges can include by one along end direction (Sperrrichtung) polarization diode and
The series circuit that control element is constituted, the control element for example can be transistor.Second leg of H bridges can include by another control
The series circuit that element processed and another diode along cut-off direction polarization are constituted.Two legs of H bridges pass through encouraging as crossbeam
Magnetic coil is connected with each other on the point between their corresponding control element and correspondence diode.In such a circuit, when two
During individual control element conducting, it can be driven by manipulation and pass the current through magnet exciting coil.If the only one in two control elements
Control element is not turned on, then electric current flows through diode that the control element with being not turned on connects simultaneously from magnet exciting coil in the loop
And flow through the control element also turned on.Thus the energy stored in magnet exciting coil is dissipated, without producing voltage peak.If
Two control elements are not turned on, then the energy stored in magnet exciting coil is flowed out in capacitor by two diodes.
But alternatively, two diodes can also be replaced by other control elements, such as transistor.For example can so it do
Manipulate transistor so that these transistors have with diode identical act on, but with less voltage drop and and this
Correspondingly there is higher efficiency.
In another particularly advantageous configuration of the present invention, at least two stators are provided with attached magnet exciting coil and effect
Element.Two functional elements are mechanically coupled, and so design the spacing w sizes between the two functional elements so that with
The inductance L of one coefficient magnet exciting coil of stator raising causes and the coefficient another magnet exciting coil of another stator
Inductance L reduces.Therefore, the spacing w between two functional elements for example can be differently configured from the distance s between two stators, its
In, two spacing can for example be supported in which can move along a straight line along common shaft centerline measurement, two functional elements along the axis.
, on the one hand can be particularly simply real by way of being alternately powered to two magnet exciting coils by the configuration
Now along the motion of two opposite directions.It is different from the reluctance actuator with only one magnet exciting coil, it can cancel for resetting
The spring of power or other sources, the spring or other predetermined undesirable mechanical intrinsic frequencies of originating.
On the other hand, energy can be reclaimed and stored in the capacitor by corresponding cold magnet exciting coil.Especially
It is in the case of reluctance actuator cycle movement, and energy seems can be reciprocal between coil and capacitor, and when
Between the net energy supplied from voltage source in terms of average value be significantly less than the net energy supplied in reluctance actuator so far.
In addition, the spacing between stator and the spacing between functional element constitute two other free degree, by this
The mechanical intrinsic frequency of two free degree adjustable mechanical reluctance actuators.Magnetic is just used in driving engine supporting arrangement
Importantly, engine mounting device can especially absorb particularly well in such frequency range in the case of resistance actuator
Undesirable vibration：The supporting force F of effectLFrequency spectrum in the frequency range have largest portion.
For the purpose, in another particularly advantageous configuration of the present invention, capacitor constitutes one with magnet exciting coil and vibrated
Loop, the vibration loop and the supporting force F periodically to act onLAt least one frequency f be in resonance in.
In another particularly advantageous configuration of the present invention, active supporting arrangement is configured with for receiving hydraulic fluid
Hydraulic pressure chamber hydraulic supporting device.Wherein, hydraulic pressure chamber is in the supporting force F acted on for receptionLReception diaphragm and be coupled to
It is on reluctance actuator, for applying opposite force FGActuator membrane between extend.Thus, it is possible to advantageously widening frequency model
Enclose, active supporting arrangement absorbs undesirable vibration in the frequency range, while can further reduce to electrical power
Demand.If such as hydraulic pressure chamber is connected by the connecting portion of throttling with concubine, then pass through rubbing for being produced when fluid is conveyed
Mistake of wearing also produces damping in the case of the electronic work of no active in supporting arrangement.This can be sufficiently used for subtracting
The weak frequency f with less than the intrinsic hydraulic pressure frequency of fluid column vibration.Reluctance actuator, and magnetic are needed only for higher frequency
Resistance actuator correspondingly consumes less electrical energy.

It is maintained on axle 42 and is movingly supported along the axis of the axle 42 with element 4, you can changes its position p.Axle 42
Axis is identical with axis 1a, and reluctance actuator 1 is on the Axial-rotational Symmetry.Functional element 4 by the air gap with width d with
Stator 2 is separated.When the axis 41 of functional element 4 is located at pMWhen on the position indicated, the inductance L of magnet exciting coil 3 is changed into most
Greatly.The position is identical with the axis of symmetry of stator 2.
The rotational symmetry structure of reluctance actuator 1 provides advantages below, i.e. magnet exciting coil 3 for manufacture to be promoted in magnetic resistance
Individually and it is wound up into before the last assembling of dynamic device 1 with high duty cycle on stator 2.
Figure 1 illustrates in the case of, magnet exciting coil 3 is not powered on.If be powered to magnet exciting coil 3, then functional element 4
Attracted downwards, until its axis 41 reaches position pM.If next be powered interrupt, then back-moving spring 11 by axle 42 simultaneously
And thus also return to the extruding of functional element 4 in the initial position shown in fig 1 a.
Fig. 2 a show the embodiment of the manipulation for manipulating the reluctance actuator 1 shown in Fig. 1 a.5 pairs of direct voltage source by
Bipolar 7 feed that control element 6 and magnet exciting coil 3 are constituted.Control element 6 is with source connection S, drain connector D and gate pole
Joint G MOSFET.By act on the control voltage on gate pole joint G can adjust drain connector D and source connection S it
Between the electric current I that flows.The source connection S being connected with magnet exciting coil 3 of control element 6 is by being antiparallel to by control element 6
The polarizing diode 12 of the sense of current be connected with capacitor 8.The diode 2 bridges magnet exciting coil 3 and therefore simultaneously
It is bipolar 7 part being made up of control element 6 and magnet exciting coil 3.If inducing voltage U in magnet exciting coil 3, such as
By the self-induction produced when rapidly switching off the electric current I by magnet exciting coil 3 or also by the supporting force F due to effectL
The motion of caused functional element 4, then as long as the voltage exceeds a threshold value Ut, voltage U drivings are in diode 12 and excitation
The electric current I being directed in the loop between coil 3.The energy stored in electric current I dissipation magnet exciting coil 3.This also occurs in control
When element 6 processed is just turned off.
Therefore, diode 12 is had the effect that, i.e., when turning off control element 6, magnet exciting coil 3 is flowed through at the time point
Electric current be not to be interrupted suddenly, but diode 12 can be continued flow through as loop current first and be continuously dissipated in
In the impedance of diode 12.It thus avoid and very high voltage peak is produced in self-induction path.
Fig. 2 b show figure 1 illustrates the reluctance actuator manipulation that passes through the asymmetric H bridges as bipolar 7.In H bridges
In left leg, connected along the first diode 12a of cut-off direction polarization with the first control element 6a.In the right leg of H bridges, the second control
Element 6b processed connects with the first diode 12b along cut-off direction polarization.Two control elements 6a and 6b are MOSFET.First
Control element 6a drain connector D is connected by constituting the control element 6b of magnet exciting coil 3 and second of H bridge crossbeams source connection S
Connect.
If two control elements 6a and 6b are conductings, then electric current I is driven by the second control member by voltage source 5
Part 6a, the control element 6a of magnet exciting coil 3 and first.If the first control element 6a is turned off, then electric current I is first as loop
Electric current continues flow through the first diode 12a and the second control element 6b also turned on.Therefore, the energy stored in magnet exciting coil 3
Amount is continuously dissipated in diode 12a and the second control element 6b impedance.If on the contrary, the second control element 6b is closed
It is disconnected, then electric current I continues flow through the second diode 12b and the first control element 6a also turned on as loop current first, with
Just continuously dissipated in corresponding impedance.If two control elements 6a and 6b are turned off, then energy passes through two simultaneously
Diode 12a and 12b are fed into capacitor 8.
Two diodes 12a and 12b need not be identical.Similarly, control element 6a and 6b need not be identical.But
Can respectively purposefully use different components, so as to for example by select pass through diode 12a and 12b in which two
Pole pipe dispersion current I influences the time constant of the dissipation.
Fig. 2 c show figure 1 illustrates the reluctance actuator manipulation that passes through the symmetrical H bridge as bipolar 7.H bridges include four
Individual control element 6a, 6b, 6c and 6d, these control elements constitute the leg of H bridges.The crossbeam of H bridges is made up of magnet exciting coil 3.Control
Each control element in element 6a, 6b, 6c and 6d processed is configured to MOSFET, and integrated one is distinguished in these control elements
Diode 9a, 9b, 9c or 9d, for the voltage sensed in magnet exciting coil 3 U to be exported in capacitor 8.Therefore, these
MOSFET is the other types for the MOSFET being different from the embodiment according to Fig. 2 a and 2b.
If control element 6a and 6d are switched on, then electric current I flows from left to right in magnet exciting coil 3 simultaneously.If
Control element 6b and 6c are switched on simultaneously, then electric current I flows through magnet exciting coil 3 from right to left.If control element 6a and 6b or
6c and 6d are switched on simultaneously, then magnet exciting coil 3 is short-circuit and is worked as electromagnetic brake.It should avoid being also turned on control
Element 6a and 6c or 6b and 6d, because voltage source 5 can direct short-circuit in this condition.
Can be reverse by the symmetrical H bridge shown in figure 2 c by the sense of current of magnet exciting coil 3.However, by magnetic
The direction for hindering the reluctance force that actuator 1 applies is unrelated with the sense of current, because reluctance force and the electric current I by magnet exciting coil 3
Into quadratic relation.
In circuit shown in figure 2, capacitor 8 and magnet exciting coil 3 collectively form a LC vibrations loop, the LC respectively
Vibration loop is the supporting force F with periodicity effectLAt least one frequency f be in resonance in.Because vehicle motor room is
The machine of periodic duty, so such periodicity supporting force FLParticularly occur in engine mounting device.
Fig. 3 shows active hydraulic supporting device 100, and the active hydraulic supporting device surrounds axis 100a symmetrically structures
Make.The hydraulic pressure chamber 101 for receiving hydraulic fluid 102 is disposed with housing 106.The hydraulic pressure chamber is upwardly through by elastomer structure

Power FL；Opposite force F is applied by actuator membrane 104G.Receive diaphragm 103 and pass through the of a substantially incompressible machine of hydraulic fluid 102
Tool is coupled in actuator membrane 104.Hydraulic pressure chamber 101 can exchange hydraulic fluid 102 with concubine simultaneously by the connecting portion of throttling
Therefore the energy of dissipation low-frequency vibration.But this is not subject of the present invention, therefore it is not drawn into figure 3 due to summary.
Actuator membrane 104 is connected with axle 105, and the axle can be moved by reluctance actuator 1 in itself.The axis of axle 105
It is consistent with the axis of symmetry 100a of active supporting arrangement 100.Two circular works are mounted with mutual spacing w on axle 105
With element 4a and 4b.Functional element 4a is associated with the coefficient first magnet exciting coil 3a of the first stator 2a.With the second stator
The coefficient second magnet exciting coil 3b of 2b are associated with functional element 4b.Stator 2a and 2b is along axis 100a with mutual distance s
Assemble with staggering.Functional element 4a and 4b is opened by the air gap separation with width d respectively with stator 2a and 2b.
Magnet exciting coil 3a and 3b are alternately powered.If be powered to magnet exciting coil 3a, then reluctance force is applied to effect
On element 4a.The reluctance force makes functional element 4a axis 4a1 move to position pM1In, the axis is with determining in the position
The sub- 2a axis of symmetry is consistent, and maximum with the coefficient magnet exciting coil 3a of stator 2 inductance L.The feelings shown from Fig. 2
Condition is set out, and axle 105 moves downward for this, and thus actuator membrane 104 is also moved downward.If the motion terminates, then effect
Element 4b axis 4b1 is consistent no longer with the stator 2b axis of symmetry.The axis of symmetry corresponds to position pM2, functional element 4b
Axis 4b1 must be positioned in the position, to make and the coefficient magnet exciting coil 3b of stator 2b inductance L maximization.
If substituting magnet exciting coil 3a now to be powered to magnet exciting coil 3b, then reluctance force is applied on functional element 4b.The reluctance force
Functional element 4b axis 4b1 is set to move back into position pM2In.Thus the state shown in Fig. 2 is re-established.
