Description

The The invention relates to an adjusting device for the automated actuation of a Gearbox according to the preamble of claim 1.

Such adjusting devices, which can also be designated as a transmission actuator, are known in the prior art in various embodiments. It is for example on the DE 195 09 477 A1 . DE 199 16 169 A1 . DE 101 28 854 A1 and DE 102 06 561 A1 directed. It is not only intended in connection with the invention of automated manual transmission of conventional type in conjunction with a single clutch, but also specifically to automated powershift transmission, especially dual-clutch transmission in conjunction with a dual clutch, thought that a zugkraftunterbrechungsfreies switching between gears of a first group of gears and gears allow a second group of gears. It can then be engaged simultaneously a gear of the first and a gear of the second group.

conventional electromechanical transmission actuators that are in use in practice usually have two electric motors, one of which for one Dialing operation and the other for one shift operation responsible is. In this way, a non-sequential switching sequence can be achieved. Such transmission actuators are mechanically relatively expensive and accordingly and also as a result of the two electric motors comparatively expensive. There are also electromechanical solutions with only one electric motor. Such transmission actuators must, as far as they have entered the practice input, sequentially switch. In addition to the binding to the sequential switching sequence is their disadvantage even in comparatively long traction interruption phases.

task The invention is an adjusting device of the type mentioned provide, without binding to a sequential switching sequence for at least some of the possible Gear change with short switching times and gets to different Operational situations and requirement profiles can be easily adapted.

to solution This object is characterized by the adjusting device according to the invention by the Features of claim 1

Provided In particular, an adjusting device of the type mentioned, which is characterized by at least one along an axis between several axial selection positions, in each case at least one input element of the Gang-insert and Exploitation mechanism are assigned, adjustable first actuator and at least one axially opposite the first actuator offset, with this along the axis jointly adjustable second actuator, wherein in positioning the first actuator in a respective one axial selection position the second actuator in association with at least one other of the axial selection position is positioned, wherein mediated by the first actuator one of the respective axial selection position assigned input element actuated is to a gear assigned to this input element, possibly the Output gear to interpret or / and assigned to this input element Gang, in particular the target gear, insert, and being under mediation of the second actuator one of the other axial selection position assigned input element actuated is to a gear assigned to this input element, possibly the Output gear to be interpreted.

The first and the second actuator can by means of a common selector drive between the dialing positions be adjustable. In that regard, already enough an actuator (possibly electric motor) for the Dialing operation off.

Further can the first and the second actuator be drivable by means of a common switching drive for input element actuation. In that regard, even an actuator (possibly electric motor) is sufficient for the input element actuation.

When It is particularly preferred that the selector drive and the switching drive having a common actuator, on its basis is the first and the second actuator both between the dialing positions adjustable and can be driven for input element actuation. In order to can by means of a single Aktuaotrs (possibly electric motor) both the dialing operation as well the input member operation respectively. There are corresponding cost savings compared to the addressed prior art.

It can be advantageously provided that the first actuating member and the second actuating member in a respective selection position of the first actuating member by means of a / are designed as a pivot drive switching drive about the axis of a neutral position in at least one deployment position can be pivoted to a possible output of the target gear containing group of courses by operating the input gear associated input element. In this context, it is mainly thought that the first actuator and the second actuator in a respective selection position of the first actuator by means of the switching drive about the axis of the neutral position in egg ner first pivot directions are pivotable in a first deployment position and in a second pivoting direction in a second deployment position to interpret a possible output gear of the target gear containing group of gears by actuating the input gear associated input element in one of the relevant pivot direction actuating direction.

Concerning the insertion of corridors is proposed as particularly preferred that the first actuator by means of the common switching drive on the deployment-actuating position also in an insert-actuating position or over the first deployment operating position out in a first insertion operating position or over the second deployment actuating position also pivotable in a second insertion-actuating position is to the target gear by pressing insert the associated input element. In this context can be provided that the second actuator in the pivoting of the first actuator in the insertion operating position or in the first or second insertion operating position in the deployment-actuating position or remains in the first and second deployment position.

At least one of the input elements may be associated with two gears of the gearbox. For this it is suggested that by operating this input element in an actuating direction, If necessary pivoting direction, a gear can be inserted or another gear can be laid out and by operation this input element in another direction of actuation, if necessary pivoting direction, the other gear can be inserted or a gear is interpretable.

It can be provided exactly one group of gears, where the gearbox for it is designed so that at a time only a maximum of one gear is inserted. It is in this context to a conventional automated manual transmission in conjunction with a normal clutch thought, in which the switching accompanied by a traction interruption is.

As already addressed, can at least two groups of transmission gears be provided, wherein the gearbox for it is designed that at a time maximum of each group only a gear is engaged. So it can be for each group (usually If two groups are provided), one transmission gear is engaged at a time be. It is here to power shift transmission, in particular dual-clutch transmission with distributed on at least two different waves transmission branches and the like thought. Within a respective group, the transmission gears independently from the gears the other group or groups be switchable.

Without Question will provide that prior to the insertion of a target gear by operation of the target gear associated input element by means of the first actuator an output gear, if previously engaged, by pressing the the input gear associated input element by means of the first or second actuator is interpretable. One opposite usual Interpretations higher Switching safety can be achieved by making pairings of Starting gear and target gear of the same group that can be inserted by operation the associated input elements in opposite insertion actuating directions and interpretable by actuation the associated input elements in opposite deployment actuating directions, the insertion of the target gear is forcibly connected with the laying out, if previously inserted, the relevant output gear by pressing the the input gear associated input element by means of the first or second actuator. It is especially thought in this context that the Layout of the output gear (if inserted at all) and the Inserting the target gear in a way in a switching process takes place. It should be noted that the training proposal itself on several, different courses refers to assigned input elements. For a single input element, that for the Placing one gear and inserting the other gear in one first direction and for the layout of the other gear and the insertion of the one gear is to be adjusted in a second direction, is the insertion of a the corridors anyway necessarily connected with the interpretation of each other's gait, and it's a higher one so far Switching safety on completely accomplished in a trivial way. After the training proposal this is higher Switching security also with respect to several input elements and their courses reached.

The first and the second actuator can along a rotary shaft to be held together displaceable. The first and the second actuator can be coupled to the rotary shaft for common rotation or be coupled. It is proposed that the first actuator be permanently with the rotary shaft is coupled for common rotation. Furthermore, will suggested that the second actuator in dependence from a current rotational position of the rotary shaft with the rotary shaft coupled for common rotation and in terms of the rotary shaft whose rotational movement can be decoupled.

A particularly preferred embodiment in this context is characterized a guide cam operable, coupled to the rotary shaft for common rotation carrier element which couples in at least one predetermined coupling rotational angle range, the second actuator with the rotary shaft for common rotation and releases in at least one predetermined Entkoppel rotation angle range, the second actuator relative to the rotational movement relative to the rotary shaft ,

It Above all, it is thought that the addressed rotary shaft part of the switching drive and that the rotary shaft for input element actuation means of the first and / or second actuator directly or via an intermediate mechanism, in particular translation stage, by an actuator (Preferably, the common actuator) is rotationally driven.

Concerning the displacement of the actuators along the rotating shaft is mainly thought that the first and the second actuator for positioning the first actuator in a desired select position directly or via an intermediate mechanism of the selector drive by an actuator (preferably the common actuator) in common are displaceable along the rotary shaft. Further training suggests that the first and the second actuator with a along the rotary shaft slidable slide for joint sliding movement coupled or coupled along the rotary shaft, wherein the slider, the part of the selector drive is, on the basis of the actuator, if necessary by means of the intermediate mechanism, a displacement movement along the rotary shaft can be dispensed.

Advantageous the intermediate mechanism can have a conversion arrangement, by means of the actuator side rotary input movement about an axis of rotation in a slide-side or actuator-side axial sliding output movement along the rotational shaft is implemented. The axis of rotation may be one opposite a rotation axis of the rotary shaft separately, preferably to this act parallel axis of rotation.

Concerning the implementation arrangement is further proposed that this one in the rotational angle direction and at least partially in the axial Direction extending guide curve arrangement and at least one with the guide cam assembly engaged, supported in rotational angle direction follower having, associated with the slider or the actuators Curve follower through the guide curve arrangement an axial sliding movement corresponding to the axial course of the Guide cam arrangement or a respective guide curve section the same is dispensable.

you may be appropriate to provide that the guide curve arrangement in a circumference, in particular outer circumference, one through the Actuator drivable and / or bewegungsverkoppel with the rotary shaft or bewegungsverkoppelbaren rotary part is formed.

A particularly preferred embodiment is characterized in that the guide curve arrangement a consequence of axial and if desired in angular direction offset from each other, at least in areas Having in the axial direction of increasing guide curve segments, means those of the cam follower by means of rotational movements of the guide cam arrangement relative to the cam follower axial sliding movements can be given and between those of the cam followers by means of rotational movements of the guide cam arrangement relative to the curve follower such übergebbar is that with the cam follower in terms of axial movement motion-coupled or couplable first actuator by means of the rotational movements between the axial selection positions is arbitrarily adjustable. In a further development, it is proposed that Areas without guide curve segments or, preferably, guide cam segments or guide curve segment sections are provided without axial pitch, so that the actuator without accompanying axial sliding movement of the cam follower is actuated, preferably while securing a momentary axial position the actuators by means of the guide curve arrangement. It can be achieved in particular, that in the case of Bewegungsverkopplung between the guide curve arrangement or the rotary part on the one hand and the rotary shaft on the other hand the Rotary shaft over at least a predetermined rotation angle range without accompanying axial sliding movement of the cam follower and thus the actuators is rotatable, especially for a swivel actuator at least one of the actuators by means of the rotary shaft for laying out and / or inserting a gear of the gearbox. One can accordingly by very simple measures achieve that by means of the common actuator without mutual disorder both the dialing operation as also the gear engagement and Auslegebetätigung is performed.

The invention further relates to a motor vehicle drive train, comprising a drive unit, a transmission and a coupling device between the drive unit and the transmission for torque transmission therebetween, wherein the transmission is switchable by means of an actuating device according to the invention. The transmission may have only one transmission input shaft, which is associated with a single clutch device with exactly one clutch assembly. The coupling device can also be a multiple-clutch device, possibly double clutch device, with a first transmission input shaft associated first coupling arrangement and a second transmission input shaft associated second clutch assembly be, and the transmission can be designed as a power shift transmission, possibly dual-clutch transmission.

The The invention further relates to a motor vehicle with a drive train according to the invention.

The The invention relates to another approach or another aspect of an actuating device for a motor vehicle, which at least one main operating element and at least one secondary operator includes. By means of the main operating element and the sub-actuators can translation levels of the gearbox are engaged and designed.

Actuators for motor vehicles are already known (eg. DE 101 33 695 A1 ), in which the gear ratios of a motor vehicle transmission with a main operating element can be inserted and can be re-interpreted by means of a secondary operating element. Here, the main operating element and the auxiliary operating element are rigidly connected. This results in the advantage that after inserting a gear by means of the main operating element, this can be turned back into the neutral lane without the gear being redesigned. To switch a new gear ratio of another shift gate, the main operating element is moved into the corresponding alley and inserted by pivoting the main operating element of the new gear. To prevent two gears from being engaged at the same time, the secondary operator releases the old gear as the main operator moves.

Of these, Starting it is an object of the invention, a further actuator for a To find motor vehicle, by means of which when switching a new Ganges the old is designed automatically.

to solution this object is inventively provided that the actuator at least a main operating element and at least one secondary operator includes, which are directly or indirectly coupled to each other. The Main control element can as a "first actuator" and the secondary actuator as "second actuator" in the sense of the above Be identifiable invention description. From the invention proposal and the following training proposals are also in this respect advantageous developments and concretizations of the above Adjusting device according to the invention.

Preferably are each main actuator two secondary actuators assigned. Most preferably, sit the two secondary actuators each on one side of the main operating element. A preferred embodiment Provides that the actuator exactly a main operating element and two sub-actuators includes. According to a further preferred embodiment, it is provided that the main operating element and the two sub-actuators on a common shaft (possibly identifiable as the above-mentioned rotary shaft of the adjusting device according to the invention) are located. It can be provided that the main actuating element rotatably connected to this switching shaft and the two secondary actuators but rotatably fixed axially fixed on the shift shaft. To an essential feature of a development of the invention the secondary operating elements coupled by turning the switching shaft with the main operating element and decoupled. The main actuating element preferably comprises a coupling element, which depending the position of the main operating element engage in a driving formation of the auxiliary operating element can, and this couples with the main actuator. Preferably become the main operating element and the secondary operating elements coupled in a neutral position of the shift shaft. Most preferably, are the secondary operating elements from the main actuator decoupled in a switching position of the main operating element. After an essential feature of a development of the invention is the coupling element connected to the main operating element in such a way that upon rotation of the main operating element is rotated and is axially displaceable to the axis of rotation. This is preferably provided that the coupling element to a first fixed guide link with a first operative portion upon rotation of the main operating element skirted becomes. This is due to the contour of the first fixed guide slot specified the displacement of the coupling element. The secondary operating elements can be beneficial also with a guide be configured, which with a second active portion of the coupling element acts. Most preferably, These are the two leading roles designed such that the coupling element in each operating state on both leadership scenes is applied.

In a further preferred embodiment of the invention, the pivoting range of the secondary actuating elements by a mechanical rotation angle limiting the fixed Führungsungskulis limited.

Preferably are the secondary operating elements with stops equipped against corresponding stops of the guide slot, during rotation the secondary operating elements, come into contact. Most preferably, are the secondary operating elements equipped with two stops, which each limit the pivoting range in one direction. To Another important feature of an embodiment of the invention are the secondary operating elements in their end positions by means of suitable retaining structures at least temporarily fixed. For this purpose, the auxiliary operating elements are preferred on her, the fixed guide scenery facing, surface with, in the axial direction of the shift shaft extending Rastierformationen configured, preferably as two parallel groove-like grooves, which can interact with a sphere of the same radius. To can the fixed guide setting, which comprises the switching shaft and the actuating elements in approximately U-shaped, with at least one spring-loaded locking element, preferably a ball, which by the spring on the surface of the auxiliary operating element depressed will be, designed. When turning the sub-actuators in one of their Endlagen arrives the Rastierelement into engagement with the corresponding Rastierformation, whereby the secondary operating elements in a local fix position. Unscrewing the secondary actuators from the end positions according to the invention requires exceeding a torque threshold, because the Rastierelemente must be pushed back against the spring force. In order to is ensured. that the secondary operating elements are not independent can move out of their end positions, but that to the coupling with the main actuator, which they Turning out of the end positions is necessary.

It It is also proposed that the pivoting range of the main operating element is greater as the swivel range of the slave operating elements. Preferably is the relative swing angle of the secondary actuators something like this large, that the pivoting range of engaging in the Schaltnuten part the secondary operating elements is about as big like the width of the switching grooves. Most preferably, the swivel range the secondary operating elements arranged relative to the switching grooves such that the secondary operating elements, Switching elements, which are in the neutral position, not move. Furthermore, the pivoting range of the secondary operating elements be designed so that they are pushed axially in switching grooves which can be inserted courses To belong. Can do this the shift groove widths should be designed so that an overlapping Range of two switching grooves, one in neutral position and the other is in shift position, at least as wide, like the fingers of the auxiliary operating elements engaging in the switching grooves.

The invention further relates to a method for switching transmission stages of a transmission by means of an actuating device, which at least one main operating element and at least one secondary operating element are associated, which are coupled together. According to the transmission ratios of the transmission can be inserted and interpreted with the at least one main operating element, with the secondary operating elements, however, the gear ratios are only interpretable. Preferably, the at least one main operating element is decoupled when inserting a translation stage of the secondary operating elements. It can be advantageously provided that the main operating element can be turned back into the selector gate after engaging the gear, without re-designing the previously engaged gear. The advantage here is that when changing the gear, the main operating element can be pushed immediately into the shift groove of the new gear to be inserted without first having to interpret the gear. The switching position of the new gear to be engaged opposite the switching position of the old gear, the main operating element after selecting the new gear, which is done by axial displacement, immediately adjusted in the direction of inserting the new gear, in particular pivoted, with the secondary operating element, which meanwhile in the shift groove of the old engaged gear, this interpretation when adjusting, in particular twisting, the main operating element. Most preferably, when returning, in particular turning back, the main actuating element from a switching position back into the neutral position, the main operating element is coupled again with the secondary operating elements. By applying the adjusting device or actuating device according to the invention and the associated method for actuating such in a drive train of a motor vehicle, which is equipped with a single-clutch device, can advantageously minimize periods with interruption of traction during switching operations. This is achieved by the fact that in case of concern of a switching command, which can be done automatically or manually, the lane of the new gear can already be selected with the clutch closed, and during the dialing or shortly before laying out the old gear, the clutch must be opened, so that during the period in which the drive train is open and traction interruption is present, only the old gear designed and the new must be inserted. According to the invention fol gender shift sequence: select new gear, open clutch, disengage old gear, engage new gear.

1 shows a schematic perspective view of an example of an actuating device according to the invention. The adjusting device according to the invention 10 serves for the selective actuation of several input elements 12 For example, in the form of shift forks, a gear-inserting and deployment mechanism of the transmission. Depending on the desired number of gears, the input members 12 be associated with two courses, with an adjustment of the respective input member 12 from a neutral position in a first direction which inserts a gear, the provision of the input member 12 in the neutral position this course again interpret the adjustment of the input member 12 from the neutral position in the opposite direction inserts the other gear, and the provision of the input member 12 again in the neutral position the other gear again interprets. It may well be provided that, for example, one of the input links 12 , Which is associated with the reverse gear, only one gear, so that an adjustment of the input member 12 from the neutral position is provided only in one direction.

For actuating the input members 12 serve an insert actuator 14 and a deployment actuator 16 (see. 2 ). The term insert actuator does not exclude that this actuator also for laying egg nes respective gear is used. When used here embodiment, the deployment actuator but only for laying out of aisles, but not to insert gears.

The insertion actuator 14 has an insert finger 18 and the lay-out actuator 16 has two delivery fingers 20-1 and 20-2 on, which is quite well as sections of a single, a gap 22 exhibiting display finger 20 can watch.

The two actuators each have a sleeve portion 24 respectively. 26 on which the fingers (insertion fingers 18 and delivery fingers 20 respectively. 20-1 . 20-2 ) extend radially outward. In the assembled state according to 1 and 2d ) is the insertion actuator 14 in one the gap 22 comprehensive recess of the extension actuator 16 used. In the relative position of 1 and 2d ) the insert finger closes 18 essentially the gap 22 ,

The sleeve sections 24 . 26 enclose in the arrangement according to 1 a rotary shaft 28 and serve for the slidable guidance of the actuators along the rotary shaft 28 , It engages one of the sleeve section 24 of the insertion actuator 14 radially inwardly projecting rib 30 in an axial groove 32 the rotary shaft 28 one, so that the rotary shaft 28 and the insertion actuator 14 are coupled for common rotation. A rotation of the rotary shaft 28 So is always with a pivoting or rotation of the insertion actuator 14 around the axis of rotation of the rotary shaft 28 connected, causing the insertion finger 18 for actuating a respective input member 12 can be pivoted against an engagement portion thereof.

The lay-out actuator 16 is considered, by itself, in the state according to 1 opposite the rotary shaft 28 rotatable or pivotable. But it is an on and off switchable Drehverkopplung with the rotary shaft 28 by means of a guiding cam-operated entrainment element 34 provided in a cross-sectionally complementary passage opening 36 the rotary shaft 28 sits in the driving element 34 is displaceable in the radial direction and with a coupling portion 38 on the axial groove 32 diametrically opposite side of the rotary shaft 28 in a V-shaped groove 40 on the inner circumference of the sleeve section 26 can engage, so the lay-out actuator 16 rotatably with the rotary shaft 28 is coupled and its rotational movement or pivoting movement in the axis of rotation of the rotary shaft 28 join in, with appropriate pivoting of the delivery fingers 20-1 and 20-2 , in particular against a respective engagement portion of one of the input members 12 to interpret a currently engaged gear.

The entrainable as a driver entrainment 34 is in the through hole 36 radially to the rotary shaft 28 adjustable, due to interaction of a cam follower surface 42 of the driving element 34 with a guide curve 44 by one in 1 lid, not shown 50 one for the arrangement of 1 associated, otherwise not shown housing is formed (see. 6a ). The design of the guide curve 44 , the entrainment element 34 and the groove 40 is such that by appropriate rotation of the rotary shaft 28 the delivery fingers 20-1 and 20-2 can be pivoted into a deployment position, in which the deployment fingers 20-1 . 20-2 against the input members located in their axial area of action 12 attack in their neutral position. A corresponding deployment actuating position is provided starting from the neutral position in both pivoting directions. This can be a respective, adjusted from the neutral position according to the insertion of a gear input element 12 by pivoting the extension finger 20-1 . 20-2 be returned in the opposite direction in the neutral position to interpret the course again. Once the respective deployment actuating position has been reached, further adjustment of the deployment actuator is achieved 16 not possible beyond the deployment position, since the guide curve 44 the entrainment element 34 releases from the groove 40 withdraw. One can - in deviation from the illustrations in the figures - provide a spring arrangement, the driving element 34 against the guide curve 44 biases. Another possibility in the representations is that section 38 and the groove 40 are executed in relation to each other, that acting in the direction of rotation forces on inclined surfaces of the groove and the section 38 acting in the radial direction, the entrainment element 34 from the groove lifting forces are implemented, so that the entrainment element 34 in a sense, automatically from the deployment actuator 16 decoupled and, accordingly, the rotational connection between the rotary shaft 28 and the lay-out actuator 16 is canceled. The lay-out actuator 16 then just takes such a pivot position that a stationary arranged locking element 52 in one of two retaining grooves 54-1 and 54-2 engages and the deployment actuator 16 in the achieved pivot position, so the respective deployment-actuating position holds. According to 6c ) is the locking element 52 formed by a spring-biased detent ball in a radially extending guide sleeve.

The rotary shaft 28 and thus the actuators 14 and 16 are by means of an electric motor Actuator 60 rotatable or schwenkantreibbar, the over a multi-stage translation 62 on the rotary shaft 28 acts. The translation 62 is formed by an output wheel of the motor 60 , a gearwheel which can also be labeled as a toothed shaft 64 , the two sections 66 and 68 of different diameters, of which the section 66 larger diameter with the output gear of the engine 60 combs, and one with the section 68 smaller diameter meshing gear segment 70 , rotatably on the rotary shaft 28 is attached, so that by means of the engine 60 the rotary shaft 28 can be rotated back and forth, with appropriate pivoting of the insertion and Auslegefinger.

With the gear 64 is a sleeve part 72 rotatably connected, the on its outer circumference a guide curve arrangement 74 having. The outer circumference with the guide curve arrangement is of a ring section 76 one of the actuators 14 . 16 associated slider 78 enclosed, and one from an inner circumference of the ring portion 76 radially inwardly projecting pin engages in the guide curve arrangement 74 one to turn as a curve follower 80 to serve. The curve follower 80 acts with a bottom of the guide curve arrangement 74 radially outwardly projecting guide curves 82 together, extending in the circumferential direction, partially without axial slope and in certain areas with axial pitch, for converting the rotational movement of the sleeve part 72 in an axial movement of the slider 78 , Axially increasing according to the embodiment shown here (see in particular the settlement in 6e ) short guide curve sections in the manner of inclined surfaces on which the curve follower 80 under axial displacement relative to the sleeve part 72 slides.

As in 6e ), an axially offset sequence of such inclined surfaces is provided, the axial displacement of the cam follower 80 including the slider 78 allows, based on the curve follower 80 essentially through the entire axial extension of the guide curve arrangement 74 (see axis A in 6e ), which is the common axis of rotation of the two-stage gear 64 and the sleeve part 72 symbolizes.

The slider 78 has one of two annular boundary sections 86 . 88 axially (relative to the axis of rotation of the rotary shaft 28 ) limited holding section 90 on, the actuators 14 and 16 according to their assembled state 2d ), in which the insertion actuator 14 in a complementary recess of the deployment actuator 16 is absorbed, so that the insertion finger 18 in the axial region of the gap 22 between the display fingers 20-1 and 20-2 located. The actuators 14 . 16 ideally have only so much axial movement play in the receptacle or relative to one another that they are substantially freely pivotable. The recording is based on the representation according to 1 and 3 designed to be open at the top and bottom, so that the only axially displaceable, so not pivotable slide 78 through the rotary shaft 28 granted pivoting movements of the actuators 14 . 16 to a required extent and not hindered. As per 1 to recognize and in 4a ), the ring-like boundary sections extend 86 and 88 of the slider 78 around the rotary shaft 28 ,

By means of the guide curve arrangement 74 and the cam follower interacting with it 80 of the slider 78 can the slider together with the actuators in the direction of the axis of rotation of the rotary shaft 28 be adjusted, in such axial positions, the selection positions of the insertion finger 18 in relation to the input links 12 correspond. Referring to the illustration in FIG 1 four select positions are provided, which correspond to the axial positions of the four input links 12 correspond. The insertion finger located in the respective selection position 18 can then with a pivoting from the neutral position, the respective associated input member 12 To engage and adjust from its neutral position, to engage a gear, or from a position corresponding to an engaged gear position back to the neutral position to lay out the gear. The other input links 12 are then each in the sphere of either the Auslegefingers 20-1 or the fly finger 20-2 such that a disengagement of an associated gear is independent of the current selection position of the insertion finger 18 can be done.

The insert finger 18 is by means of the guide curve cam follower arrangement 74 . 80 between in each case one of the input members (shift fork pairs) 12 assigned axial selection positions adjustable, in which then the dialing position associated input member 12 in the area of action of the insertion finger 18 is located and operable to interpret a gear assigned to the input member and - especially - for inserting a gear assigned to the input member. The other input links 12 are then in each case in the sphere of the delivery finger 20-1 and 20-2 , As long as the rotary driving connection between the laying-out actuator 16 and the rotary shaft 28 by means of the entrainment element 34 is made, the insert finger move 18 and the delivery fingers 20-1 and 20-2 together as a one-piece, extending over the entire axial extent of the group of input links 12 extending actuating finger, until the deployment position (deployment pivot position) is reached and the driving element 34 releases the deployment actuator so that it then locks over the latch 52 . 54 in this position (deployment-actuating position or deployment pivot position) is maintained. Upon further rotation of the rotary shaft 28 in the same direction of rotation then pivots the insert finger 18 beyond the deployed actuating position further into an insert actuation position (insertion pivot position). A corresponding state of the actuator 10 is in 7 shown.

The described embodiment is particularly useful for the operation of a simple transmission with a number of gears, of which only one gear may be engaged at a time or can. For example, in the context of dual clutches, powershift transmissions, especially dual clutch transmissions, have become known, which have two groups of transmission gears, one gear being able to be engaged at a time from each group. The advantage of such powershift transmission is a zugkraftunterbrechungsfreies switching by way of a so-called overlap circuit in which an output gear and a target gear are engaged and by simultaneous disengagement of the output gear associated clutch assembly and engaging the target gear associated clutch assembly, a transfer of the drive torque from the output gear having transmission branch at the target gear having transmission branch in a continuous manner, without interruption of traction, is achieved. It is useful if the even gears form a group of gears and the odd gears a different group of gears, so that sequential switching without interruption of traction is possible. An adjusting device according to the invention can also be advantageously adapted for switching such a dual-clutch transmission. For this purpose, it is expedient if the input members 12 alternating courses of one and the other group of courses are assigned. 5 shows an adapted to such a design interpretation actuator 16 ' , with two display fingers 20-1 ' and 20-2 ' , between which one of the axial dimension of three input members corresponding gap 22 ' is provided. Is the insertion actuator 14 in the space provided for this purpose the deployment actuator 16 ' recorded, so remains between the insert finger 18 and the delivery finger 20-1 ' a gap 22-1 ' and between the insert finger 18 and the delivery finger 20-2 ' a gap 22-2 ' just the axial dimension of one of the input links 12 corresponds to the transmission, so that a pivoting operation of the actuators may relate only to an input member spaced apart input members. The operation can only be affected by corridors that belong to the same group of aisles. This ensures that the one or more courses of a group of courses related switching affects no gear of the other group, so neither interprets nor inserts.

In the following, the embodiment of the 1 to 4 . 6 and 7 With reference to a transmission with only one group of gears. The assignment of the gears to the input links and their directions of actuation, for example, be as in 6d ) and 7d ). One of the input links is assigned only to the reverse gear R. The input member following in the axial direction is assigned to the first and the second gear. According to 7 the first gear is engaged, while according to 6 no gear is engaged. The next input member is assigned to the third and the fourth gear and the last input member is assigned to the fifth and the sixth gear. The arrangement of the designation R, 1, 2, 3, 4, 5 and 6 on the one or the other side of the input members indicates in which direction the respective input member is to be adjusted in order to engage the respective gear. Engaging one of these gears is from a movement of the cam follower 80 in an associated guide groove of the guide curve arrangement 74 connected, which extends only in the circumferential direction, so that the curve follower 80 no Axiabewegung is granted. The assignment of the guide grooves and the direction of movement of the cam follower 80 in the respective groove when inserting the respective gear is on both sides of the settlement according to 6e ) and 7e ) indicated by an arrow and the relevant passage designation. To insert the first gear has the curve follower 80 from a guide cam array portion having the inclined surfaces for axial displacement in the by the designation 1 identified groove according to the direction of the arrow, in 6e ) So, to the left, moves, and a movement of almost 360 ° in the groove executed against the direction of movement for the insertion of the second gear, around the sleeve part 72 around, from the other side to the inclined surfaces having portion of the guide cam assembly 74 come on, like out 7e ) can be seen. The grooves are thus executed closed except for the inclined surfaces having area. The grooves are thus respectively associated with two gears, the fifth and sixth gears, the third and fourth gears, the first and second gears and finally - alone - the reverse gear R, and they differ with respect to the guide cam arrangement 74 the even and odd gears each only the directions of movement of the cam follower 80 in the respective groove.

The operation of the presented adjusting device is particularly well clear from a Fol ge of state representations according to the 6 and 7 while performed by the actuator switching sequences. It is assumed that starting from a condition that no gear is engaged (neutral state, 8th ; the actuators are in their rest positions or neutral positions), the first gear is to be inserted. According to 8th takes the insert finger 18 already the first gear assigned dialing position. The 9 to 13 illustrate the pivotal movement of the actuators for engaging the first gear, and according to 14 then the first gear is engaged. Thereafter, the actuators are returned to the rest or neutral position ( 15 to 21 ; in 21 the neutral position is reached and the first gear is still engaged.

If the second gear is then to be engaged, this can be done from the sequence of 22 to 27 apparent way. According to 27 the second gear is engaged. 24 shows an intermediate state in which the first gear is just completely designed again and the adjustment of the first and second gear associated input member from the neutral position in the opposite direction of actuation just starts.

The episode of 28 to 33 illustrates the return of the actuators in the rest position or neutral position. According to 33 the actuators take exactly the neutral position and the second gear is still engaged.

The episode of 34 to 41 then illustrates a way to shift to third gear. According to the 34 to 36 First, an axial adjustment of the cam follower and thus the slider together with the actuators by means of the inclined surfaces of the guide curve arrangement, according to 36 the third and fourth gear associated groove is reached. The 36 to 41 then illustrate the layout of the second gear by means of the deployment finger 20-1 and the insertion of the third gear by means of the Einlegefingers 18 , wherein the laying and inserting takes place in the course of a rotational movement of the rotary shaft by means of the actuator. According to 41 the third gear is engaged.

42 to 48 illustrate then the return of the actuators in the neutral position, while still engaged third gear. The downshift to first gear can then be switched on from the episode of 49 to 62 apparent way. 53 shows an intermediate stage in which, as a result of a corresponding pivoting movement of the actuators, the third gear is just designed, which then uses a pivoting movement of the actuators in the opposite pivoting direction for engaging the first gear. The state of the inserted first gear shows 62 , A provision of the actuators in the neutral position while continuing to engage first gear to prepare an axial adjustment of the actuators to select another gear pair can then again according to the sequence of 15 to 21 respectively.

The processes are very similar when switching a dual-clutch transmission as previously explained. 63 shows a suitable for the switching of a dual clutch transmission design of the guide curve arrangement, now with 74 ' designated. The assignment of the gears to the four input links 12 can be like in 64 specified. The one group of gears is formed by the reverse gear, the second, fourth and sixth gears and the other group of gears of the first, third, fifth and seventh gears. Thus, for example, the first and second, or the second and third or the third and fourth or the fourth and fifth or the fifth and sixth or the sixth and seventh gear can be simultaneously engaged if a sequential switching sequence without interruption of traction is desired. However, for example, the first and the sixth gear may well be engaged at the same time. In 64 is the insert finger 18 symbolically represented for a dialing position assigned to the first and third gear. From the two symbolically illustrated delivery fingers 20 ' only one assumes an axial position, in which an input member is in its effective range, namely the input member associated with the fifth and seventh gears.

Based on the state of 64 For example, according to the sequence of 65 to 67 when the clutch is engaged, the first gear is engaged, whereupon the clutch is engaged and the actuators are returned to the selection or rest position ( 68 ). Then, in the example used here, the second gear is then selected ( 69 ). 70 and 71 illustrate the insertion of the second gear, in addition to the first gear. In the state according to 71 can then be reversed between the two clutches (so-called overlap circuit). According to 72 For example, the clutch associated with the even gears may be fully engaged and the clutch associated with the odd gears may be fully disengaged. The actuators are moved back to the rest or selection position.

According to 73 then that's it again th and third gear associated input member selected, for example, to advance to third gear. According to 74 the first gear is designed and then according to 75 the third gear is engaged in addition to the second gear, whereupon the clutches can then be disengaged. According to 76 the ungradzahligen the gear trains associated clutch is fully engaged. For switching to fourth gear, the fourth and sixth gear input member is then selected ( 77 ). By means of one of the deployment fingers then the second gear is designed ( 78 ) and then inserted by means of the insert finger fourth gear ( 79 ), whereupon it is then reversed between the clutches. After resetting the actuators in the selector or neutral position ( 80 ) is then assigned to the fifth and seventh gear input member by corresponding axial adjustment of the insert finger 18 selected ( 81 ) and then first the third gear by means of one display finger 20 ' designed ( 82 ) and then the fifth gear by means of the Einlegefingers 18 inserted ( 83 ), whereupon it is then reversed between the clutches. The laying out of the fourth gear and the subsequent insertion of the sixth gear can then accordingly 84 to 87 followed again by a coupling between the two clutches of the double clutch. In a corresponding manner, it is possible to switch further into the seventh gear or also back to low gears without traction interruption. A shift from the second to the first gear and from this then in reverse is in the 88 to 91 illustrated.

Advantageous structural and functional features of the embodiments described are in particular the following:

• - Inserting the gears by a slidably mounted on a shift shaft insertion fingers. By entrainment formations on the shift shaft and corresponding counter-driving formations on the insertion of this is indeed axially displaceable, but rotatably connected to the torque transmission with the shift shaft.
• - Laying of the gears by a deployment finger, which is axially displaceable and lockable for torque transmission to the shift shaft.
• - Locking the deployment finger with the switching shaft by means of a driver, which is controlled via a guide contour for locking and releasing.
• - In the case of only one group of gears, the deployment finger sweeps over all the input members (shift fork pairs) not crossed over by the insertion finger. It is thus each currently engaged gear (output gear) when inserting the next gear (target gear) interpretable, either by the insert finger or by the deployment finger.
• - The insertion of a gear by the deployment finger is prevented by forced release (unlocking) of the deployment finger by the driver.
• - A detent associated with the deployment finger prevents it from swinging beyond the maximum angle of rotation provided. Emigration of the deployment finger from its end position is prevented.
• - The transmission actuator is driven by a single electric motor, of which the torque is transmitted via a gearing on a gear ratio and translated by an appropriate gearing design. The translation stage forwards the torque via a suitable toothing on a gear segment on.
• - With the translation stage rotatable a markable as a backdrop guide curve arrangement is connected, which acts by suitable curve selection an axial displacement of the input and Auslegefinger means of a slider. The external displacement of the slider is realized by serving as a cam follower, for example, in the slider pressed pin, which engages in the contour of the backdrop. The slider has a receptacle for the deployment finger and the insertion finger, so that he can move it on the shift shaft according to the specifications through the backdrop. The shift of the insert finger axially to the shift shaft causes the selection of a desired gear.
• - The torque is transmitted through the gear segment, which is non-rotatably and axially fixed to the shift shaft, transmitted to the shift shaft. The switching shaft transmits the torque via positive engagement on the shift finger (insert finger and deployment finger), which are designed as levers and thus transform the torque in the switching power for engaging or disengaging a gear.
• - For the operation of a transmission with several independently switchable groups of gears, such as a dual-clutch transmission, the delivery finger can be designed so that it no longer covers all not currently selected by the insert finger input members (shift fork pairs). In order that at the same time two adjacent passages can be inserted, which are assigned to adjacent input links, the delivery finger can be configured such that it always passes over input links spaced apart from an input link. The remaining components of the transmission actuator may be identical to the transmission actuator for a transmission having only one group of gears, resulting in equal parts advantages.
• - In conjunction with the mentioned excursion transmission of the extension finger and the shown assignment of the transmission gears to the input members (shift forks) (R and second gear on an input member, first and third gear on a second input member, fourth and sixth gear on a third input member and fifth and seventh gear on a fourth input member ) can be interpreted by means of Auslegefingers only gears, which are two courses above or below the current, based on the insertion finger gear.

In 92 is a further embodiment of an actuating device according to the invention (also referred to as adjusting device beschfigurbar).

The actuator is according to 92 engaged with symbolically illustrated shift rails 117 (generally input elements or input elements). In the constructive embodiment of the actuating device shown here, the auxiliary actuating elements which can be identified as a disengaging actuating member or disengaging actuating members in the sense of the above description are 102 formed in one piece and sleeve-like. Essentially, the secondary actuators are 102 arranged on a tubular base body, which a switching shaft bore 116 having, with which the secondary operating elements 102 rotatable but axially fixed on a not shown switching shaft (rotary shaft) 103 are attached. The secondary operating elements 102 are designed as shift finger (Auslegefinger), which lie in a common plane in which also the axis of the switching shaft bore 116 located. The two adjacently arranged sub-actuators 102 are separated by a gap that is about as wide as the strength of a shift rod 117 ,

The main actuation element identifiable as an insertion actuator in the sense of the above description 101 , which rotatably with the shift shaft, not shown 103 is connected, engages from the inside through the tubular body of the auxiliary operating elements 102 by. In this case, the shift finger (insert finger) of the main operating element protrudes 101 in the gap, which by the two shift fingers of the auxiliary operating elements 102 is formed. On the side opposite the shift fingers side of the auxiliary operating elements 102 are two parallel to the switching shaft hole 116 running Rastierformationen 115 appropriate. The Rastierformationen 115 here are groove-shaped, so a ball 113 can intervene positively in this. Furthermore, a coupling element 104 (Identifiable as the driving element in the sense of the above description corresponding functional element) to see, which is perpendicular to the switching shaft bore 116 extends and through the tubular body of the secondary actuators 102 extends to the outside. The coupling element 104 is formed in the shape of a cuboid, wherein the two opposite sides, which extend radially inward and radially outward, are wedge-shaped. The side of the coupling element 104 , which are radially inward into the switching shaft bore 116 extends, may, with appropriate location of the main operating element 1 to the secondary operating element 2 in a driving formation 5 , which in the switching shaft bore 116 is trained, intervene. As the main operating element 101 rigid with the stem 103 is connected, and the coupling element 104 only perpendicular to the switching shaft 103 may shift the main actuator 101 and the coupling element 104 do not twist against each other. A rotation of the switching shaft 103 So always requires a pivoting of the main operating element 101 and the coupling element 104 , Lying the shift finger of the main operating element 101 and the sub-actuators 102 in a plane, the coupling element can 104 into the driving formation 105 engage and the main operating element 101 with the sub-actuators 102 couple. Are the main operating element 101 and the sub-actuators 102 coupled in this way, requires a rotation of the switching shaft 103 a swinging of all shift fingers.

In 93a to 96b is a functional sequence of a gear change with an actuator according to the invention shown in two dimensions. Here are the 93a . 94a . 95a . 96a two-dimensional sectional drawings of the actuator according to the invention from 92 at the level of the coupling element 104 perpendicular to the switching shaft bore 116 , The 93b . 94b . 95b . 96b show cuts through the actuator 92 at the height of the ball 113 , The cutting plane is again perpendicular to the switching shaft bore 116 , The 93a and 93b show the current position of the actuator 92 , The main operating element 101 lies in the plane of the shift rod 118 and has pushed this to the left in a switch position. The secondary operating element 102 engages in 93a in the shift rod 119 one. The guiding scenery 106 encompasses the switching shaft 103 with the main operating element arranged thereon 101 and the slave actuator 102 U-shaped and extends in the direction of the stem. The coupling element 104 , which is perpendicular to the switching shaft 103 is able to move is with its first effective section 108 at the first guide setting 106 guided and with its second effective section 109 on a second guide 107 , which mostly from the Schaltwellenbohrung 116 consists. In 93a is clearly seen that the main operating element 101 and the slave actuator ment 102 are decoupled.

In 93b it can be seen that the secondary operating element 102 locked in its left end position. This is the ball 113 by means of the spring 114 in the Rastierformation 115 pressed. A pivoting movement of the auxiliary operating element 102 can only overcome the spring force of the spring 114 respectively. After a desired gear, which with the shift rod 118 switched is inserted, becomes the main operating element 101 turned back.

In 94a It can be seen that after successful turning back of the main operating element 101 the shift fingers of the auxiliary operating element 102 and the shift finger of the main operating member 101 to lie in one plane. When turning back the shift shaft 103 counterclockwise, the coupling element 108 along the first guide track 106 guided and thereby relative to the switching shaft 103 moved vertically. Here, the second active section engages 109 of the coupling element 104 into the driving formation 105 the secondary operating element 102 one. This is in this position of the actuating element in 94a the main operating element 101 and the slave actuator 102 coupled. In 94b can be seen that during the pivoting back of the shift shaft 103 counterclockwise the secondary actuator 102 did not go along. Occurs from the switching position of the actuating element 94a a shift request, the actuator is axially displaced so that the shift finger of the main operating element 101 in the plane of the shift rod of the new gear is. During this selection process, the clutch does not yet need to be opened, and the vehicle continues with the old gear. Towards the end of the selection process or else only after the completion of the selection process, the clutch is opened and at the same time or subsequently the old gear by means of the auxiliary operating element 102 designed. For this purpose, starting from 94a , respectively. 94b the shift shaft 103 further rotated counterclockwise, the shift shaft by means of the coupling element 104 with the auxiliary operating element 102 rotatably coupled. This pushes the shift finger of the auxiliary operating element 2 the shift rod 118 the old gear back to the neutral position and puts out the old gear. The shift finger of the main operating element 101 moves freely during the Auslegevorganges the old gear in the shift groove of the shift rod 117 of the new corridor. The ball 113 becomes against the spring during the laying process 114 pressed back, then in the second groove of Rastierformation 115 the secondary operating element 102 to fix. This is the secondary operating element 102 raced in its second end position.

The 95a and 95b represent the state of the actuator after laying out the old gear. To insert the new gear, which here exemplified the shift rod 117 is assigned, the shift shaft 103 rotated according to the shift position of the new gear. If the shift position of the new gear is opposite to the shift position of the old gear, the shift shaft 103 just continued to turn.

In 96a the position of the actuating element is shown after the insertion of the new gear. Here is the switching position of the new gear, which with the shift rod 117 connected by sliding it to the right. This is the switching shaft 103 has been further rotated counterclockwise, wherein the secondary operating element 102 , like out 96b can be seen in his position 95b remained. A rotation of the switching shaft 103 in the switching position of the new gear here has a displacement of the coupling element 104 from the driving formation 105 the second guide slot 107 causes. On the other hand, the shift position of the new gear is in the same direction as the shift position of the old gear 93a , starting from 95a , in which all gears are designed, the shift shaft 103 turned clockwise. This causes a rotation of the switching shaft 103 a simultaneous pivoting of the main operating element 101 and the sub-operation element 102 , there, how out 95a it can be seen, the secondary operating element 102 by means of the coupling element 104 with the switching shaft 103 rotatably coupled. The shift fingers of the main operating element 101 and the sub-operation element 102 move freely in the switching grooves of the shift rails during this time. Reached the shift finger of the auxiliary operating element 102 its left end position and gets through the ball 113 rests in this end position, requires further rotation of the shift shaft 103 in the clockwise direction, a final coupling of the main operating element 101 and the sub-operation element 102 , By further rotation of the switching shaft 103 clockwise pushes the shift finger of the main actuator 101 the shift of the new gear to be inserted to the left and puts it with it.

With the Bettigungsvorrichtung invention For automated manual transmissions, shorter shift times are possible. This is achieved by the fact that the clutch only during the actual gear engagement open must be and not anymore during of the dialing process the actuator in the switching level of the new gear to be inserted.

In 97 is a two-dimensional section through an alternative actuator Height of the ball 113 shown. The ball 113 and the associated spring 114 are here in a locking sleeve 123 housed which one pushing out the ball 113 from the guide sleeve 122 through the spring 114 avoided. This is the locking sleeve 123 equipped on the side pointing in the direction of the switching shaft with a diameter which is less than the diameter of the ball 113 , This safety measure of the ball 1113 is especially necessary for assembly, as during the assembly process the ball 113 not by the slave operator 102 is held. Furthermore, the fixed guide slot 106 with mechanical angle limits 120 fitted. The secondary operating element 102 is with stops 121 equipped, which with the mechanical rotation angle limits 120 correspond. The angle of rotation limits 120 are designed as inwardly extending stops. The attacks 121 the secondary operating element 2 and the rotation angle limits 20 the guide scenery 6 are arranged such that they each in the end positions of the pivoting range 111 the secondary operating element 102 come to a stop with each other. This ensures that even when the spring action of the spring decreases 114 the secondary operating element 102 its swivel range 111 maintains and does not insert by turning further beyond the end positions out a gear.
