Output block 14,15 jointly and side by side is bonded on force output member 7 places.This point exemplarily by in the side of output movement 12,13 upwardly extending connecting rod 16 realize, yet wherein, other connects type also is feasible.
The driving force that mode by electricity produces can drive the output block 14 of electric drive unit 2 to carry out its output movement 12.Under the situation of pneumatic drive unit 3, the driving force that is used to produce relevant output block 15 output movements 13 produces in pneumatic mode, that is, produce by pressurized air.
By means of electric control device 17, can realize coordinated with each other the actuating of two driver elements 2,3 adapting with the application.Driver element 2,3 can side by side move thus sometimes, and/or sometimes alternately the operation.
For example, can when the beginning of power output movement 8, carry out both sides' operation to reach higher acceleration.During the interstage subsequently, can for example carry out pneumatic drive unit 3, (whenever necessary) have the isolated operation of higher travelling speed.At the processing completion time used for them of power output movement 8, can for example carry out the isolated operation of electric drive unit 2, carry out the accurate localization of force output member 7 in this period.The particularly advantageous mode of both sides' control is described in file DE 103 27371 A1 to some extent.
Two driver elements 2,3 all are embodied as Linear actuator in all embodiments.Output movement 12,13 is linear motion, and it is preferably consistent with the moving direction of the power output movement 8 that is similarly linearity.In form of implementation not shown further, one or two in the driver element 2,3 is implemented as the rotary driver that can produce the rotation output movement, can for example draw (for example swinging) the power output movement 8 that is similarly rotation from this rotation output movement.
In this embodiment, two driver elements 2,3 are independently of one another.They comprise two independent output blocks of having mentioned 14,15, and this output block 14,15 can act on the common relevant force output member 7.Yet, without doubt, can also jointly be assigned single output block for these two driver elements 2,3, the driving force that this output block both can have been produced by the mode with electricity acts on, and also can be acted on by the driving force that produces with pneumatic mode.The feasible embodiment who is used for this structural type is disclosed in file DE 102 44 260 A1.
Linear direct driver in example, have be formed in its actuator housing 5, in the side of output movement 12 upwardly extending holding space 18, affiliated output block 14 slidably is contained in this holding space 18.By output block 14, holding space is divided into two chambers 22,23 vertically, and their volume changes according to the physical location of output block 14.Holding space 18 preferably is closed on distolateral.Output block 14 can be designed to piston-like.
The electric drive unit 2 that is designed to linear direct driver is included in mode two drive units 24 interact with each other to drive on the basis of electromagnetism, 25, wherein, one, promptly first drive unit 24 is arranged on the actuator housing 5, and another person, promptly second drive unit 25 is arranged on the output block 14.First drive unit 24 (only shown in broken lines in the drawings) is made of coil device, and coil device comprises a plurality of in succession driver coils coaxially.It is along the whole stroke of output block 14 and extend.
Two drive units 24,25 are based on the electrodynamics principle and concurrent operation.By electric control device 17, the driver coil of first drive unit 24 can one after the other be energized individually or in groups in time, wherein, the magnetic field interaction of the permanent magnet 26 of the magnetic field that is produced and second drive unit 25, so that produce such reaction force, this reaction force acts on the output block 14 in the mode that depends on polar orientation, to be implemented in the output movement 12 on a direction or another direction.This reaction force acts on driving force on the output block 14 in this formation.
The Linear actuator of pneumatic drive unit 3 for for example constructing according to the form of the pneumatic linear actuator of routine, but at this, the modification of piston-rodless also may be utilized.Output block 15 is designed to piston, its be arranged under actuator housing 7 in the upwardly extending inner space 27 of output movement 13 sides, and, by seal action this inner space 27 axially is divided into two work chamber 28,29.Feed one that has in the fluid passage 32,33 independent of each other respectively in each work chamber 28,29, by this passage, pressurized air can be infeeded or be emitted selectively, so that desirable driving force is applied on the output block 15.
For pneumatic drive unit 3 is carried out control corresponding, preferably have the control valve device of handling in the mode of electricity 34, this control valve device 34 has two exit from dos (Arbeitsausgaenge) 35, link one that has in this fluid passage 32,33 respectively at these exit from do 35 places.Control valve device 34 comprises supply interface 36 in addition, and this supply interface 36 is connected with source of compressed air 37, or can be connected with source of compressed air 37.
At last, control valve device 34 also comprises at least one and is preferably two waste gas outlets 38,39 that the waste gas that (at its run duration) is extruded out from pneumatic drive unit 3 can flow out in the atmosphere by this waste gas outlet 38,39." waste gas " refers to such air---and it is current discharges in such chamber from two work chamber 28,29 by output block 15, and this chamber is in the state that volume dwindles based on the output movement 13 of the output block 15 of orientation correspondingly.
The running state of control valve device 34 is determined by electric control device 17 in the mode of electricity.
As example, control valve device 34 has 5/3-valve function, and wherein, it can be embodied as the continuous valve device.Way of realization as the shift valve device equally also is feasible.If need not to provide intermediateness, then 4/2-valve function also may be enough.In all cases, realize this function respectively or by single control valve only or the multistage layout by control valve coupled to each other on the function.
The great advantages of all shown hybrid drives is, has such device, and it plays following effect, that is, the guiding pneumatic drive unit 3 accumulation in service waste gas at least in part, be preferably fully and pass electrodynamic element 2 as cooling air.Therefore, the waste gas of pneumatic drive unit 3 was used to cool off electric drive unit 2 before being drained into atmosphere.Cooling effect is especially significant, and reason is that waste gas is owing to inflation process (this inflation process is along with its discharge takes place) has quite low temperature.Expansion is by following former thereby cause, that is, waste gas is before as being in the pressurized air under the relative elevated pressures and being transfused in the relevant work chamber 28,29 to cause opposite output movement 13.
In order to reach desirable cooling effect, waste gas can be guided through electric drive unit 2 in any way on principle.And so a kind of layout is both effectively and economical, and in this arrangement, cooling air flows through the actuator housing 5 of electric drive unit 2.Yet, additionally or alternatively, cooling air also can for example be directed flowing through output block 14.
In the embodiment in figure 1, the actuator housing 5 of electric drive unit 2 is run through by cooling air channels 42, this cooling air channels 42 preferably extends on the direction of output movement 12, and be preferably located in the drive unit 24 that is associated with actuator housing 5 near.Cooling air channels 42 at one end is attached to two waste gas outlet 38,39 places of control valve device 34 simultaneously via exhaust piping 43 (for example flexible pipe or pipeline).At the other end, cooling air channels 42 is communicated with atmosphere by outflow opening 44.Connection based on two waste gas outlets 38,39 time, cooling air channels 42 air stream that all is cooled on two moving direction of the output block 15 of pneumatic drive unit 3 runs through.The combination of two waste gas outlets 38,39 can for example realize by corresponding pipe fittings.
Obviously, on actuator housing 5, also can be formed with other cooling air channels 42, be provided for waste gas cooled from these two waste gas outlets 38,39 to these cooling air channels 42 equally.
If control valve device 34 is directly installed on actuator housing 5 places and is communicated with this at least one cooling air channels 42 by the housing internal channel, then can not use independent exhaust piping 43.
In the embodiment of Fig. 2, the waste gas of exporting via two waste gas outlets 38,39 is directed to electric drive unit 2 places as cooling air independently of one another.Be extended with at least two cooling air channels 42 in actuator housing 5, it does not connect each other, and in direct mode or to be linked to each place in these two waste gas outlets 38,39 independently of one another by the mode that continues of exhaust piping 43.Like this, depend on the moving direction of the output member 15 of pneumatic drive unit 3, in the mode that replaces, perhaps only exhaust piping 42 or only another exhaust piping 42 air that is cooled flow through.The outflow opening 44 of cooling air channels 42 can be arranged to the end face side actuator housing 5 places as in other embodiments, yet this is not compulsory.
In the embodiment of Fig. 2, two waste gas outlets 38,39 are connected with the cooling air channels 42 that preferably stretches in parallel with each other aptly by this way,, make that these two cooling air channels 42 are flow through on the axial direction of output movement 12 on opposite directions that is.Producing especially thus in electric drive unit 2, even temperature distributes.To the air supply of these two cooling air channels 42 can be in particular reciprocally point to the channel end place carry out so that the outflow opening 44 of cooling air channels 42 equally reciprocally points to, especially the end face side be positioned at actuator housing 5 places.
The extension that is parallel to output block 14 moving direction of one or more cooling air channels 42 has the following advantages, that is, all such zones---in this zone heat release take place---and all are exposed in the cooling air.
But at least one cooling air channels 42 also extends around holding space 18 to spirality.
Except a difference, the embodiment of Fig. 3 is consistent with the embodiment of Fig. 2.This difference is, these two cooling air channels 42 respectively are linked to each place in top mentioned two chambers 22,23 by at least one branched bottom 45, and these two chambers 22,23 are separated from each other by output block 14.This has caused, and quite a few in the waste gas of pneumatic drive unit 3 can enter in the chamber 22,23 that is linked, so that the support of power aspect is provided for the driving of output block 14 by executing of the end face of output block 14 carried.Just when this assembly starts---at this moment, the static friction in the in most cases the highest pneumatic drive unit 3 must be carried out and overcome---and such measure makes the introducing of power additional, pulsed become possibility.Even output block 14 is with respect to relevant actuator housing 5 blow-by, thus waste gas partly overflow go in corresponding another chamber, still---shown according to the measurement of being carried out---have the effect of auxiliary driving force.
Obviously, preferably with waste gas outlet 38,39 as follows across with these two chambers 22,23 are connected, promptly, feasible always such chamber 22 or 23 is executed to be carried, and this chamber is orientated identical with reference to the moving direction of output block 7 with the current work chamber 28,29 that is executed the pneumatic drive unit 3 of carrying with pressurized air.
Because this power is auxiliary, the efficient of hybrid drive 1 can further improve.Generally speaking, can understand like this this, promptly, under situation according to the hybrid drive 1 of Fig. 3, the waste gas of pneumatic drive unit 3 is used to the cooling of electric drive unit 2, and, can be used in electric drive unit 2, produce additional drives power based on its residual pressure that still has.
If actuator housing 5 comprises a plurality of cooling air channels 42, then these cooling air channels 42 can be positioned to (being preferably equably) and distribute around holding space 18, to realize cooling especially uniformly.Especially, if actuator housing 5 is implemented as extrusion in its all border district limits the longitudinal cross-section of this holding space 8, one or more such cooling air channels 42 then also can be set, and this cooling air channels 42 extends around this holding space 18 on relatively large circumferential lengths.So, this cooling air channels 42 can especially have the cross section of circular arc, and directly forms in the manufacturing of extrusion.
As the replacement in the wall that is integrated in actuator housing 5, at least one cooling air channels also can be shaped as independently channel component, for example is shaped as the cooling air pipeline, and it for example is arranged in actuator housing 5 places in the outside.
In the atmosphere around cooling air can directly be discharged into after flowing through cooling air channels 42.Yet, also can on corresponding outflow opening 44, link baffler, flow noise to reduce.
