These blocking elements can also be moved together by a moveable conversion shift fork.
Another form of implementation of invention defines：Movable clutch components are one, especially have armature portion
Part or the adapter sleeve being movably disposed in rotor axial, it can be harmonious in coupling position by a brake apparatus with shape
Upper locking.This improves functional safety and position reliability of first clutch components on coupling position.
Brake apparatus can be realized differently.A solution define using movable intermediary element (such as
Ball), these elements cause adapter sleeve directly or indirectly to be coupled with armature assembly or rotor by other parts.In these
Between element moved to by a de- disconnected device on coupling position, and be maintained at also by it on this coupling position.
In this case it is contemplated that：Intermediary element is pressed onto in a vacancy attached troops to a unit by de- disconnected device (to be taken off disconnected in other words
Device makes all intermediary elements move in the vacancy for being associated with them), and vacancy can be closed.
According to a kind of form of implementation of invention, for uncoupling, vacancy or a receiving slit being adjacent have one
Individual inclined-plane, the intermediary element for making to attach troops to a unit when moving axially by this inclined-plane are moved into the position of uncoupling again.
The vacancy of intermediary element is in particular arranged at adapter sleeve the inside in itself.
As it was previously stated, invention is directed to a kind of method for manipulating the electromagnetic clutch according to invention.This method regulation：Electricity
Magnetic coil is disconnected electric current when realizing that shape is harmonious and connected, so as to power saving.

Weighing apparatus is reliably there occurs if.
Actuator preferentially starts simultaneously with the energization of magnet coil, or with its having time offset carry out manipulate and/
Or be stopped again, in other words for return movement turn-off current or simply temporarily work.
After this connection process terminates, that is to say, that after part coupling, make magnet coil and actuator preferential
Disconnect.
In addition can be by the on-position of Sensor monitoring actuator, and be back to when drive device stops
Original position.(line of force is separated).
When stopping, the return of clutch components with can also separately have connects actuator to enter by temporarily manipulating
OK.
Described method and step can also be arbitrarily mutually combined.

Embodiment
The electromagnetic clutch that can be connected with electromagnetically-operated is illustrated in the accompanying drawings, as they are in particular for the sky of automobile
Adjust compressor such.
Electromagnetic clutch is driven with a drive shaft represented with axis A.Drive shaft passes through a driving of itself
Motor or explosive motor and move.One driving part 10 is a part for drive shaft or coupled with drive shaft that it sets
Count discoid, be especially designed to sleeve.
On driving part 10, end face and axially through connecting element 12 movably and circumference has been fixedly disposed one
Individual armature assembly, it is especially designed to disk, and in addition preferentially has the rubbing surface 16 of end face side.In armature
One or several spring elements 18 are housed, they make armature assembly 14 to the side of rotor 20 between part 14 and driving part 10
Upward pretension.
The rotor 20 for forming the output of clutch is located at the opposite of rubbing surface 16, and has the contact surface of an end, rubs
Wiping face can be abutted on this contact surface.Rotor 20 is rotatably arranged in the shell 24 of clutch by bearing 22.Turning
A belt, chain or a gear teeth are for example acted on the excircle of son 20, correspondingly rotor 20 can have on excircle
There are the groove or tooth of abnormity.But the mode for transmitting torque is not limited.
In an illustrated embodiment, rotor 20 has the reception cavity of a ring-type, has one or several magnet coils 30
Stator 28 be arranged in this reception cavity.
Armature assembly 14 can be attracted by the energization of magnet coil 30, that is to say, that in the direction towards rotor 20
On.
By a wire 32 being connected with control device 34, as also described later, temporarily to magnet coil
30 are powered.
One adapter sleeve for forming mobilizable first clutch components 36 and driving part 10 are axially movable and anti-
Connect to torque.There can be a gear teeth 38 for this driving part 10, this gear teeth meshing is on first clutch components 36
A corresponding gear teeth 40 in.
First clutch components 36 has a gear teeth 42 on excircle, and it can be with second by axial movement
The gear teeth 44 of clutch components 46 engage.
Second clutch components 46 be rotor 20 a part either one it is directly or indirectly coupling with rotor 20,
The connected part in anti-rotation ground, here in the form of a kind of ring, has the gear teeth 44 radially inward.
One actuator 48 that equally should be also connected with control device 34 forms the straight line of first clutch components 36
Drive device.
Actuator 48 is, for example, a magnetic linear drive device being fixed on shell 24.Filled provided with a machine insurance
Put for preventing the intermeshing gear teeth from disengaging.This safeties is here integrated in the gear teeth 42,44.
The gear teeth 42,44 can be seen in Fig. 1 a and 1b well.The gear teeth 42,44 are designed to the self-locking on direction is connected
's.Each tooth 50,52 of the gear teeth 42 or 44 has a mutually opposite top and ladder tapered into towards backward end
Shape main body.By towards the main body tapered into top reverse end, seeing in the axial direction, shape on each tooth 50,52
Into side recessed 54.
Fig. 1 represents electromagnetic clutch under non-couple state, and wherein rubbing surface 16 has spacing with rotor, equally also like the
As one clutch components 36 with second clutch components 46 has spacing.
In this state, rotor 20 stops, driving part 10 can rotate (such as in motion) or do not rotate (
When automobile stops).
Fig. 1 a illustrate phase mutual spacing, not be intermeshed tooth 50,52, they allow with second clutch components
46 first clutch components 36 disengaged rotate.
If it is desired that DRIVEN BY AIR CONDITIONING COMPRESSOR, and rotate rotor 20, then give magnet coil 30 by control device 34
It is powered, so that armature assembly 14 is to moving on the direction of rotor 20, that is to say, that along the connecting element 12 for being used as being oriented to.
Driving part 10 is preferentially fixed in the axial direction, but is not necessarily required to so.
Once rubbing surface 15 encounters rotor 20, that just accelerates rotor 20 by frictional connection.
If the rotating speed of rotor 20 and driving part 10 is balanced, that is activated by actuator 48 so that first clutch
Device part 36 moves right in the axial direction.Tooth 50 is also just to the right between the tooth 52 (see Fig. 1 b) of second clutch components
Motion, so as to form a kind of torque connection in a circumferential direction.
Magnet coil 30 then again can with turn-off current because torque simply forcibly by clutch components 36,46 it
Between connection transmit.
In order to exclude face-off tooth 50,52 just mutually run into end face and therefore prevent first clutch components 36
Axial movement to the right, several measures can be taken, they can be with single or cumulatively use.
The mutual opposite end of tooth 50,52 is for example come to a point so that they mutually can aside be slipped over.
In addition one can be provided between first clutch components 36 and driving part 10 in a circumferential direction
Small―gap suture, this allows for the gear teeth 42 to realize a kind of rotational motion of avoidance.
In driving part 10 and therefore in addition the turn-off current of magnet coil 30 is made in operation of actuator 48, so as to the
One clutch components 36, and rotor 20 and small rotational motion therefore can be realized between second clutch components 46,
This allows to make the gear teeth 42,44 be aligned in a circumferential direction, if the gear teeth 42 axially move on the direction of the gear teeth 44.
Second clutch components 46 no longer automatically can be moved on the position of uncoupling, because recessed by side
54, this side is recessed to lead to wedge surface close to each other (see Fig. 1 b) in a circumferential direction, and an axial movement is produced when transmitting torque
Power, this force figure make the gear teeth 42 be maintained on coupling position.
If it is desired that compressor of air conditioner disconnects again, then in opposite direction operation of actuator 48, so that first clutch
Part 36 is moved to the left on the position of uncoupling again.
That is first clutch components 36 moves axially under load effect.
According to Fig. 2 second of form of implementation in terms of features described below with the difference shown in Fig. 1, wherein function phase
Same or same component is using used label.Existing part is no longer illustrated, and may refer to figure here
1, therefore be described in detail below for the difference part of form of implementation.
Actuator 48 is second magnet coil in the form of implementation according to Fig. 2, and it is preferentially equally also positioned at rotor
In 20 vacancy, and it is considered as a part for stator 28.
This actuator 48 is also connected with a control device not shown here.
First clutch components 36 is by an elastic spring-or reset element 56 towards uncoupling position
Pretension on the direction of (position in Fig. 2), and be positioned between driving part 10 and first clutch components 36.
For clutch components 36 by being located on second armature assembly 58, the latter radially outward extend out to actuator 48 always,
And device can be performed to tense and/or push open.Armature assembly 58 is coupled by several connecting elements 60 with driving part 10, its
In have a small gap between driving part 10 and armature assembly 58 in a circumferential direction.
This gap can for example be realized as got off：It is (such as long that an excessive opening 62 is provided with armature assembly 58
Aperture), this opening allows have a circumferential clearance with the connecting element 60 attached troops to a unit (see Fig. 2 c)
See in radial directions, ground is offset with the gear teeth 42 on circumferencial direction, be provided with and incline in first clutch components 36
Oblique, especially wedge-shaped shifting block receives seat 64 (see Fig. 2 d), and the shifting block extension 66 of the corresponding wedge shape of armature assembly 58 is stretched
Enter this shifting block to receive in seat.
When being coupled into, friction plate 16 is set to be moved towards rotor 20 first, so that rotor 20 accelerates.It is balanced in rotating speed
Operation of actuator 48 afterwards, armature assembly 58 is set to continue to move right.
Very simple figure is illustrated in fig. 2, actually connecting element 60 allows armature assembly 58 to move right, even in
After the contact rotor 20 of rubbing surface 16.It is correspondingly to be carried out in the scope of armature assembly 58 for this such as rotor 20
Fluting.Also stir first clutch components 36 via shifting block extension 66 by mobile.
If tooth 50, if 52 mutually encounter, by elongated hole 62 can realize armature assembly 58 and therefore first
The defined balance of clutch components 36 rotates.Once tooth 50,52, more precisely, most wide on the circumferencial direction of tooth 50,52
Position mutually aside slips over, then first clutch components 36 can be transported to the right than the armature assembly 58 that then selection is kept
It is dynamic more.This last motion stage can be possible to also automatically carry out due to side recessed 54.Finally reach according to Fig. 2 b's
Coupling position.
Because the spring-force driven dual of spring element 56, still may be also in spite of side recessed 54 on the direction of pushed-open position
At least must minutely it be powered to actuator 48.Magnet coil 30 however generally reach shape phase between clutch components 36,46
With regard to already off during the connection of conjunction.
Actuator 48 is set to disconnect or change poles in uncoupling, therefore spring and/or actuator 48 make first clutch
Part 36 and armature assembly 58 are back on uncoupling position.
In previously-described embodiments, actuator 48 is always provided in the encapsulation object of rotor 20 and stator 28, preferentially
In rotor 20.
But according to the form of implementation shown in the following drawings, actuator 48 is always located in outside encapsulation object, preferentially very
To outside shell 24.
Fig. 3 represents a kind of form of implementation, wherein being designed to that the actuator 48 of linear drives couples with selector fork 68 again.This
For ensureing the rectilinear movement of a connection disk 70, this connects disk again on rotor 20 or the inside, equipped with axially movable
The blocking element 72 of setting.
The especially locking bearing pin of blocking element 72.
These blocking elements 72 form first clutch components 36 with connecting together with disk 70.Second clutch components 46
It is made up of armature assembly 14, there is the latter corresponding vacancy 74 to be used to lay blocking element 72.
Vacancy 74 and/or the preferential tapered extension of blocking element 72 come to a point in other words, so as to balance in circumferencial direction
On different relative position between rotor 20 and armature assembly 14, and a kind of axial phase mutual connection can be realized
Close.
In this form of implementation, there can also be relative rotation connecting between disk 70 and conversion shift fork 68.Therefore space
Requirement very little, component is also simpler.In addition actuator 48 can be made arbitrarily to position.
In the past as described in form of implementation in, synchronization is realized by magnet coil 30, this magnet coil has attracted
Armature assembly 14.Armature assembly 14 has on a circle, the vacancy 74 of spacing very little.In then operation of actuator 48 and movement
During blocking element 72, these blocking elements are moved near their vacancy 74, so as to by the inclined-plane and chamfering of importing,
After the cutout in short-term of magnet coil 30, it is possible to achieve the minimum relative rotation of rotor 20, for fully making blocking element 72
It is aligned with vacancy 74.Therefore blocking element 72 can be made to be moved fully in vacancy 74, and realizes shape phase in a circumferential direction
The connection of conjunction.
Magnet coil 30 is preferential at the latest in this moment turn-off current.
It is designed to that the blocking element of bearing pin can be according to Fig. 3 b and c equally also by the vacancy 74 of also taper
Corresponding side recessed 73, is maintained on the position of locking (Fig. 3 c), similar to picture such case according to tooth 50,52 in accompanying drawing above
Described in as.
In addition, spring catcher can be used for the state remained up, as this uses spring in Fig. 3 d and 3e
100 and braking member 102 it is represented as.
Actuator 48 is set to be activated in opposite direction in uncoupling, so that blocking element 72 goes out for 74 lira from vacancy.
In the form of implementation by Fig. 4, first clutch components 36 is an adapter sleeve, and it is axially movably located at
On armature assembly 14, and it is connected with its torque.
Such as 42 are toothed around on first clutch components 36 end face (this is not necessarily required to), it can be with
The gear teeth 44 on second clutch components 46 engage.Second clutch components 46 is also located on rotor 20 to anti-rotation here.
First clutch components 36 passes through intermediary element 76 that is mobilizable, being movably arranged (being ball here), axial direction
Coupled with armature assembly 14.Intermediary element 76, circumferentially, they are located at first clutch components to plurality of distribution arrangement
36 attach troops to a unit in vacancy.Armature assembly 14 has a circumferential groove 78 for carrying inclined-plane 80 facing radially towards these vacancies.
One so-called pusher 82, it unclamps but can grasped in the axial direction in a circumferential direction with conversion shift fork 68
Connect vertically, it is used to ensure：In operation of actuator 48, after synchronization, pass through armature assembly 14 and the electricity being powered
Intermediary element 76 is radially pressed into vacancy and is pressed into inwards in groove 78 by magnetic coil 30 dearly.Make first by intermediary element 76
Individual clutch components 36 move to the right on the direction to second clutch components 46.Simply when the gear teeth 42,44 are intermeshed
When (see Fig. 4 b), intermediary element 76 is just located in groove 78 radially inwards, so as to so that pusher 82 continues to move right, cross
Intermediary element 76.
Then intermediary element 76 is no longer in the circumferential groove of a inside of pusher 82, therefore this pusher is so-called
Surmounted intermediary element 76, and intermediary element be maintained in the vacancy of first clutch components 36 and circumferential groove 78 in.It is logical
Cross this measure and propose a kind of so-called brake apparatus, this device is maintained at first and second clutch components 36,46
On coupling position.
Actuator 48 need not apply a lasting axial force again now, and it may be possible to if, or even disconnect electricity
Stream.
For uncoupling, actuator 48 makes pusher 82 be back to initial position by changing shift fork 68, thus by from
Intermediary element 76 that mental and physical efforts outwards load also due to inclined-plane 80 outwardly against.Once intermediary element 76 is entered in pusher 82 again
When in the circumferential groove of face, first clutch components 36 is set to stir together to the left.
By tooth form (sketch 4b) return can also be made favourable.Its wedge shape makes an axial direction by torque in an on state
Power acts on clutch components 36, and therefore acts on intermediary element 76.When pusher 82 is moved and returned, this pusher
The braking of intermediary element 76 is released, and the gear teeth push back clutch components 36, and intermediary element is moved and moved out together.
In this this form of implementation, in order to avoid end contact crown, can also before operation of actuator 48 or
The electric current of period, temporarily cutoff solenoid 30.
In the form of implementation by Fig. 5, pusher 82 is axially movable equally also as first clutch components 36
Ground is supported in rotor 20.Circumferential groove 78 equally also forms out in rotor herein.The gear teeth 42 are, for example, one first
The end face gear teeth on individual clutch components 36, the corresponding opposed gear teeth 44 are arranged on armature assembly 14.
The gear teeth 42 are by several teeth 50 arranged in groups, and wherein these component cloth are circumferentially and phase mutual spacing.In circle
42 groups of the gear teeth are gone from the inner stretching of tongue projection point 84 in circumferential direction, and the latter is passed through in the vacancy 86 of rotor 20.Therefore also result in
Rotate synchronous (see Fig. 5 a and b).
It is substantially the combination by the feature of Fig. 1 and 4 form of implementation by Fig. 6 form of implementation.On armature assembly 14
Movably and torque coupling be provided with first clutch components 36, this part can by an external gear teeth 42 with
One gear teeth 44 on second clutch components 46 of rotor-side engages.
The gear teeth of the gear teeth equivalent to Fig. 1.
The actuator 48 of outside arrangement moves right first clutch components 36 by changing shift fork 68, to make wheel
Tooth 42,44 is intermeshed.
In this form of implementation, as remaining, once causing shape to be harmonious if connection, coil can also be made
30 no currents.One no longer necessary by the axial force actuator 48, because the corresponding geometry of the gear teeth 42,44
Cause the power on coupling position direction.
For uncoupling, make the counter motion of actuator 48, so that the gear teeth 42,44 are released under load effect.
Naturally, can also be provided with spring element in all forms of implementation, they help to be pressed into and extruded.
Different method of operating can be used in all forms of implementation.On the one hand, as repeatedly being described as before, example
Such as make magnet coil 30 realize shape be harmonious connection when turn-off current, wherein shape be harmonious connection can be by sensor 90
(such as see Fig. 6) detects.
For this alternatively magnet coil 30 can also disconnect after the latter prespecified time of beginning that is powered,
In this time, it is reliably enough used to accelerate rotor 20.
Additionally or alternatively, actuator 48 can be made to be powered with magnet coil 30 to start simultaneously, or also may be used
To be manipulated and/or be disconnected with the wrong shifting of this time.
Rotating speed balance can certainly be measured by sensor.
It is returned to when drive device stops, such as by operation of actuator 48 in short-term, realization on uncoupling position.Therefore
Separate the line of force again.
