in the In contrast, in known devices from the prior Technique provided that the gear actuator substantially completely assembled and then into the gearbox is set or attached. This is done in the prior art, for example so that all Parts of the gear actuator are mounted in an actuator housing, and that actuator housing then attached to the gearbox, for example, screwed.

These Type of installation can lead to the prior art that very large openings in the gearbox necessary to enable that the mountability is ensured and the required Interfaces of the gear actuator to the inner gearshift to be provided.

Thereby that according to the invention two separate Modules of the gear actuator also stored separately on the gear housing can be, for example, allows be that the actuation module or a switching shaft with arranged thereon actuators and optionally other components, for example, the previously described type, substantially axially through a corresponding opening into the gearbox introduced and stored there. The drive module can then be transverse to this, for example with one or two electric motors, or selector motor and switching motor, and a transfer mechanism, which extends to the interface of the drive module for dialing and for switching, across to the longitudinal extent the shift shaft are mounted.

It In particular, it may also be provided that - as mentioned - the actuation module through an opening in the gearbox introduced substantially axially will and another opening in the gearbox is provided, on or in which the drive module is used, so that allows is that the appropriate interfaces to the actuation module achieved or created.

In 2 the exemplary inventive design is shown in the assembled state. Here is the gear actuator 42 on the gearbox or on the gearbox housing 88 the transmission device 1 mounted or stored.

Through the arrows 60 . 62 are schematically the mounting devices of the two individual components "actuation module 56 '' and "drive module 58 '' symbolized, and these can preferably be complained only in the order given. The arrow 60 symbolizes the mounting direction of the actuating module 56 and the arrow 62 symbolizes the mounting direction of the drive module 58 ,

Between the actuation module 56 and the drive module 58 or in the transition area between these two modules 56 . 58 There is a kinematic interface for switching and a kinematic interface for dialing. The kinematic interface for switching is in 3 with the reference number 64 provided and the kinematic interface to choose is in 3 with the reference number 66 Mistake.

The following will now - in particular with reference to 4 - on the components of the actuator module 56 To be received:
The actuation module 56 has a shaft or shift shaft 50 on that with a (first) rack 68 is provided. The (first) rack 68 extends in the longitudinal direction of the switching shaft 50 and is of several in the longitudinal direction of the shift shaft 50 spaced, for example, each circumferentially closed teeth 69 educated. The (first) rack 68 is for the dial kinematic 101 intended. It forms part of the interface for dialing 66 between the actuation module 56 and the drive module 58 , The Betätigungsmo dul 56 also has a gear segment 70 with an approach 72 on. The approach 72 serves to allow a referencing of the circuit diagram and / or as part of a shift gate. Instead of such an approach 72 but may alternatively be provided a differently designed part, by means of which a referencing of the circuit diagram allows and / or a shift gate is formed. But it can also be alternatively provided that the actuation module 56 free from such a part as approach 72 , is.

The gear segment 70 is designed or arranged so that the teeth in the circumferential direction of the shift shaft 50 are spaced apart and each substantially in the longitudinal direction of the shift shaft 50 extend. The gear segment 70 is for the switching kinematics 100 intended. The gear segment 70 is part of the interface 64 between the actuation module 56 and the drive module 58 for switching.

The actuation module 56 further comprises actuating means or actuating elements 74 . 80 . 86 on. By means of these actuators 74 . 80 . 86 can on the final output mechanisms or the shift rails 28 . 30 . 32 . 34 be acted on for laying and laying out of aisles.

The actuating element device or the actuating element 74 is a combined actuator of one or more secondary actuators 76 and a main actuator 78 , The actuating element device or the actuating element 74 can be formed in one piece, for example.

The actuating element device or the actuating element 80 is also a combined actuator of a main actuator 82 and one or more slave actuators 84 , The actuating element device or the actuating element 80 can be formed in one piece, for example.

The main 78 . 82 and sub-actuators 76 . 84 are part of an active-interlock mechanism. In this regard, reference is made to the introductory notes to the Active-Interlock. The active interlock may, for example, in the embodiment according to the embodiment, be developed and / or configured, for example, as it was explained in the beginning of this present disclosure, and in particular has also been explained with reference to known designs.

The main actuators 78 . 82 are designed as shift finger. The secondary operating elements 76 . 84 are designed as double wings.

The gearbox or internal gearbox with the input shaft 10 and the main waves 12 . 14 and the inner transmission circuit 26 has a transmission housing 88 on or is in a transmission housing 88 recorded that in 2 schematically and partly by two the wall boundaries schematisierenden dashed lines is partially shown. In addition, the gear actuator can 42 an actuator housing 44 have, for example, a - possibly additional - support function for components of the actuator 42 can have.

5 shows a view of the switching motor 46 as well as the selector motor 48 from the gear housing outside (see. 2 ).

5 can also be seen that the actuator housing 44 an extension 44a has, which is here plate-shaped. The extension 44a can for example in one piece with the actuator housing 44 be connected or trained. Instead of such a plate-shaped extension 44a For example, a hood-shaped projection can be provided. But it can also be provided, for example, that the actuator housing 44 has a modified form, and is free of an extension.

The extension 44a has several (first) holes or through holes 89 for receiving screws. By means of these screws 91 is the actuator housing 44 or the drive module 58 on the gearbox 88 stored or mounted. Instead of such a fastening device for the drive module 58 However, also a differently designed attachment device for the drive module 58 be provided.

It can be provided that the actuator housing 44 or its extension 44a several, in particular two, second holes or through holes 93 for receiving centering pins 91 having. By means of these centering pins 91 can a game-related deviation between the desired and the actual position of the drive module 58 or of the actuator housing 44 or its extension 44a on the gearbox 88 be reduced or avoided. Instead, however, for example, centering or the like may be provided.

The actuation module 56 is separate from the drive module 58 on the gearbox 88 stored. Advantageously, for the actuation module 56 , on the one hand, and for the drive module 58 , on the other hand, separate openings in the transmission housing 88 intended.

It can be provided that the actuator housing 44 or its extension 44a at the same time as Cover for at least partially closing the opening of the transmission housing 88 serves, through which the drive module 58 in the gearbox 88 is used. The drive module 58 is - like for example 2 shows - partially inside and partly outside the gearbox 88 positioned. The actuator housing 44 or its extension 44a or the addressed lid, for example, releasably on the transmission housing 88 be mounted or fixed.

The actuation module 56 or the switching shaft 50 is completely in the gearbox 88 positioned. Alternatively, however, it may also be provided, for example, that the actuation module 56 or the switching shaft 50 end on one or both sides of the stem 50 from the gearbox 88 protrudes.

The actuation module 56 or the switching shaft 50 axially displaceable and rotatably mounted. The actuation module 56 or the switching shaft 50 is on the gearbox 88 stored. For this purpose, it can also be provided that on the transmission housing 88 one or more extensions are attached, the or from the extension 44a are different, and at which or on which the actuating module 56 or the switching shaft 50 is stored; This may, for example, be expedient with regard to the fact that the actuation module 56 or the switching shaft 50 is mounted axially displaceable. Such an extension or such extensions, for example, directly on the gear housing 88 or on walls or a wall of this gear housing 88 be attached or molded, and extend for example from there to the inside.

It is thus provided in particular that the actuation module 56 or the switching shaft 50 , on the one hand, and the drive module 58 on the other hand, separately on the gearbox housing 88 are stored. This is especially so that in principle the actuation module 56 or the switching shaft 50 on the gearbox 88 can be mounted or storable, without the drive module 58 on this gearbox 88 stored or mounted, or vice versa. It should be noted, however, that this is to be expressed that the actuation module 56 or the switching shaft 50 , on the one hand, and the drive module 58 , on the other hand, separately on the gearbox housing 88 are mounted or stored; The aforementioned should in particular not mean that optionally the actuation module 56 or the drive module 58 as a gear actuator 42 can be used or installed; to the gear actuator 42 rather belong both the actuation module 56 as well as the drive module 58 ,

In contrast to known from the prior art design is in the embodiment according to the 2 to 10 - And this is one of several aspects that make a difference to the prior art - the gear actuator 42 in two separate functional modules, namely a drive module 58 and an actuation module 56 , is divided, in particular provided that their function as a whole is possible only with a corresponding transmission periphery. This allows - and at least in further developments - space gaps can be used variable. The fact that the function as a whole is only possible with a corresponding transmission periphery is to be understood in particular as meaning that the transmission periphery or a corresponding transmission periphery is required so that the function of the actuator is ensured. It is provided in particular that without a corresponding transmission periphery, the function would not be ensured for the reason that the drive module 58 or the actuation module 56 would not be sufficient. In contrast, it is possible with known design that the gear actuator generates its output movement, generated by means of at least one electric motor, by means of which an internal gearshift circuit can be actuated for selection or shifting, without the gearbox actuator being mounted on the gearbox or on the gearbox housing.

6 shows a section along the line VI-VI 5 , and 7 shows a section along the line VII-VII 5 , The sectional view according to 6 is a section through the selection kinematics 101 of the gear actuator 42 , and the cut according to 7 is a section through the switching kinematics 100 of the gear actuator 42 ,

In the 6 shown dial kinematic 101 indicates or consists of a motor or dial motor 48 with (first) drive toothing 90 , a (first) ring gear 92 with (first) spur wheel extension 94 , a pin or an axis 96 and a (first) sheet metal 98 , The selector motor 48 is preferably an electric motor. The (first) drive toothing 90 on the dial motor 48 is provided, can directly into the motor output shaft of this selector motor 48 be introduced or be rotatably mounted as a separate toothing or as a separate, toothed part on this motor output shaft.

The (first) ring gear 92 with the (first) spur wheel extension 94 is such that it has an internal toothing and for the formation of the (first) Stirnradfortsatzes 94 an axially offset external toothing forms. The (first) drive toothing 90 of the selector motor 48 engages in the addressed internal teeth and thus can the (first) ring gear 92 , and thus its (first) Stirnradfortsatz 94 , drive. The gear or (first) ring gear 92 stands with his (first) Stirnradfortsatz 94 engaged with the (first) rack 68 of the actuating module 56 , This is so that the (first) spur gear extension 94 in the (first) rack 68 engages and thus by rotation of the (first) ring gear 92 or its (first) Stirnradfortsatzes 94 the shift shaft 50 about the engagement of the (first) spur wheel extension 94 in the (first) rack 68 can be moved axially.

The (first) ring gear 92 is on the pin or axis 96 stored.

The gear actuator 42 has an actuator housing 44 on. In this actuator housing 44 is the pin or axis 96 firmly mounted on one side or firmly pressed. On the other side forms a (first) sheet metal 98 the bearing point for the pin or the axle 96 , The (first) sheet 98 is by its chosen shape radially and axially on the actuator housing 44 fixed.

So it is through the (first) sheet metal 98 a bearing function for the pin or the axle 96 created. The pin or axis 96 takes the (first) ring gear 92 together with (first) spur wheel extension 94 rotatable on.

The switching kinematics 100 (see. 7 ) has or consists of a motor 46 (Shift motor) with (second) drive toothing 102 , a (second) ring gear 104 with (second) spur wheel extension 106 a spur gear 108 , a bearing component 110 , a spindle 112 , a (second) rack 114 and an axial / radial bearing unit 116 ,

The (second) drive toothing 102 the shift motor 46 , which is preferably an electric motor, can in the motor output shaft of this switching motor 46 be introduced. But it can also be provided that this (second) drive toothing 102 is introduced, for example, in a sleeve which is non-rotatably connected to the motor output shaft of the shift motor 46 connected is.

This (second) drive toothing 102 acts on the internal toothing of the (second) ring gear 104 a, so that by means of (second) drive toothing 102 or by means of the switching motor 46 the (second) ring gear 104 can be driven in rotation. At the (second) ring gear 104 is the (second) spur wheel extension 106 axially offset or axially overlapping to the internal toothing of the (second) ring gear 104 arranged.

The mentioned (second) Stirnradfortsatz 106 of the (second) ring gear 104 engages the spur gear 108 a, so that by means of the (second) Stirnradfortsatzes 106 or by means of the switching motor 46 the spur gear 108 can be driven in rotation.

The spur gear 108 sits firmly on the spindle 112 so that the spindle 112 with the spur gear 108 is rotated when this spur gear 108 rotates.

On the spindle 112 sits the (second) rack 114 or a spindle nut 118 on which the (second) rack 114 is arranged. The spindle nut 118 can be integral with the (second) rack 114 be formed, or as a separate part on this spindle nut 118 be fixed.

The spindle 112 is substantially rotatable and axially substantially fixed, so that by turning the spindle 112 an axial wandering of the mother 118 or the (second) rack 114 can be effected. It can also be provided that an axial guide in addition to the leadership of the spindle nut 118 or the (two) rack 114 is provided.

The (second) rack 114 engages the gear segment 70 so that the (second) rack 114 as well as the gear segment 70 Part of the between the actuation module 56 and the drive module 58 provided (kinematic) interface 64 for switching.

The spindle 112 on the one hand by means of the bearing component 110 and on the other hand by means of the axial / radial bearing unit 116 stored. In the design according to 7 are the bearing component 110 and the axial / radial bearing unit 116 essentially in the area of the two opposite distal ends of the spindle 112 arranged.

The bearing component 110 is in the embodiment required or expedient, because due to the special design and assembly order of the subassembly "spindle 112 '' one far from the actuator housing 44 remote radial bearing point for the spindle 112 is needed or appropriate. The position or exact positioning of the spindle 112 on or to the actuator housing 44 is by or by means of fixing or positioning of the bearing component 110 with the adapter component 120 set. The torque is with the bars 122 . 124 on the bearing component 110 supported (cf. 8th ).

By means of the bearing component 110 can be achieved, for example, that an inside, exposed and accurate storage is possible. Such a design can also ensure the assembly at the same time.

As 7 shows, is the spindle 112 substantially parallel and transversely to its longitudinal extension direction spaced from the motor output shaft of the electric motor or switching motor 46 arranged, by means of which the spindle ( 112 ) is drivable. The longitudinal direction or longitudinal axis of the motor output shaft of the electric motor or switching motor 46 or a concentric Ach se is in 7 schematically by the dashed line 125 clarified.

According to the design according to 7 or in the design of the switching kinematics 100 is the motor or switching motor 46 right next to the spindle 112 arranged. For example, a short design of the switching kinematics 100 be reached, for example, also partly uses the transmission interior or projects into this gear interior.

It can be provided that the motor or switching motor 46 , by means of which the spindle 112 can be driven, - preferably completely - axially between the opposite ends of the spindle 112 is located.

9 shows an enlarged section 7 in the area of the axial / radial bearing unit 116 ,

The axial / radial bearing unit 116 indicates or consists essentially of a one-sided open carrier 126 , in particular one-sided open plastic carrier 126 , an axial needle bearing 128 , a first thrust washer 130 , a second thrust washer 132 , a - in particular caulked - sleeve 134 , one in the spindle 112 introduced groove 136 , a radial bearing tread 138 , Axialabstützflächen 140 . 142 and housing support surfaces 144 . 146 ,

In the area of the outer shell of the spindle 112 becomes a depression 148 educated. This depression 148 becomes radially inward through the spindle 112 limited and in the axial direction on the one hand by the paragraph 150 the spindle 112 and on the other hand through the sleeve 134 , Axial between these axial boundaries of the recess 148 are the thrust washers 130 . 132 , which are axially spaced from each other, each trapped. Axial between these two thrust washers 130 . 132 is the axial needle bearing 128 arranged or caught, which is around the spindle 112 extends around.

The carrier 126 , in particular a plastic carrier 126 is pointing to his the spindle 112 facing side of a depression 152 on. In this depression 152 extends in each case a radially outer region of the thrust washers 130 . 132 ,

Furthermore, between these radially outward areas of the thrust washers 130 . 132 a section of the axial needle bearing 128 located. The support of the axial forces takes place alternately or the radial bearing force according to the in 9 illustrated, black outlined white arrows. The radial bearing force acts essentially only in 9 below or in the lower part of the spindle 112 ,

In the following, it will now be explained how the thrust bearing force alternately via the axial / radial bearing unit 116 can be supported.

First, however, it should be noted that the thrust washers 130 . 132 each rotatable relative to the spindle 112 and rotatable relative to the (plastic) carrier 126 are arranged.

If now an external axial force, essentially in the direction of the arrow 154 acts on the spindle 112 acts, presses the spindle 112 with her heel 150 on the second thrust washer 132 , The load of the spindle 112 axially on the second thrust washer 132 acts, loads the second thrust washer 132 axially, thereby the axial needle bearing 128 loaded, which in turn axially the first thrust washer 130 loaded. The first thrust washer 130 rests in the area of the axial support surface 140 while on the (plastic) carrier 126 in turn, in the area of the housing support surface 144 on the actuator housing 44 supported. Under the mentioned load conditions, a frictional connection between the spindle essentially arises 112 and the second thrust washer 132 in the area of the paragraph 150 the spindle 112 so that the second thrust washer 132 essentially with the spindle 112 rotates; Furthermore, there is essentially a frictional connection between the first thrust washer 130 and the (plastic) carrier 126 in the area of the axial support surface 140 , so the first stop disk 130 essentially - as well as the plastic carrier 126 - rest.

If now on the spindle 112 an axial load according to the direction of the arrow 156 acts, the spindle is supported 112 over the sleeve 134 at the first thrust washer 130 axially. The first thrust washer 130 in turn supports axially on the axial needle bearing 128 starting, which accordingly the second thrust washer 132 loaded axially. The second thrust washer 132 rests in the area of the axial support surface 142 axially on the (plastic) carrier 126 which in turn axially in the area of the housing support surface 146 on the actuator housing 44 supported.

The unit from the two thrust washers 130 . 132 and the intermediate thrust needle bearing 128 is with a certain axial play in the recess 148 as well as with some axial play in the pit 152 , To the bottom of the well 152 have the thrust washers 132 . 130 and of course also the axial needle bearing 128 a certain amount of play, so that the corresponding distortions are possible.

As explained, the axial / radial bearing unit 116 designed so that they have a one-sided open plastic carrier 126 having only one axial needle bearing 128 and only two thrust washers 130 . 132 needed.

On the other hand, in the prior art designs (where applicable, applicant's own prior art so that the Applicant reserves further protection), such bearings are constructed to require two axial needle bearings and three thrust washers. In the known from the prior art designs, the three thrust washers are arranged axially spaced, wherein between each two adjacent thrust washers each one of the Axialnadellager is positioned. The axially outer thrust washers are coupled in the cited prior art with the bearing shell and lying in the middle thrust washer is doing with the spindle 112 coupled, or vice versa.

10 shows an enlarged section 3 in a slightly tilted shape. In 10 Among other things, a device or components is shown, which ensure a referencing of the internal-circuit diagram or form a backdrop. This device for enabling a referencing or for forming a backdrop is in 10 with the Bezugszei chen 160 Mistake. The device 160 points to the already mentioned approach 72 on, on the actuation module 56 or the switching shaft 50 is fixed.

The device 160 also has a (second) sheet or two (second) sheets 162 on. This (second) sheet or these (second) sheets 162 are on the drive unit or the drive module 58 fixed. It can be provided that the or the (second) sheets 162 on the actuator housing 44 are mounted. The (second) sheet 162 or the (second) sheets 162 extend on radially opposite sides of the shift shaft 50 , It can be provided that these sections, on radially opposite sides of the switching shaft 50 are arranged, are integrally connected, so that a (second) sheet metal 162 given is. But it can also be provided that this - as described above - separate (second) sheets 162 are. The following is given priority of two (second) sheets 162 spoken, without the possibility that these are designed as a (second) sheet, thereby excluded.

In the (second) sheet 162 are on both sides or in the (second) sheets 162 are each several openings or windows 164 . 166 intended. It should be noted that instead of the (second) sheets 162 also differently shaped parts, in particular parts of the actuator housing 44 , Plates or less flat-building components may be provided, in which openings or windows 164 . 166 or depressions are provided.

The following is for simplicity, however, of windows 164 . 166 spoken, it should be noted that these may be in particular breakthroughs, or that instead of corresponding wells may be provided.

The distance and the number of windows 164 . 166 is due to the design of the shift rails 28 . 30 . 32 . 34 determines or depends on this. In particular, the distance of the windows 164 . 166 from the distance of the shift rails 28 . 30 . 32 . 34 (to each other) dependent.

In the windows 164 . 166 can depending on the direction of rotation of the actuator module 56 or the switching shaft 50 the approach 72 swing in, provided that this height or in the axial direction of the shift shaft 50 or of the actuation module 56 on the same level as the window in question 164 respectively. 166 stands. In the fields of 168 . 170 between the windows 164 respectively. 166 is not a rotation of the actuator module 56 or the switching shaft 50 possible. Gleichmassen is no height adjustment or adjustment in the axial direction of the shift shaft 50 or the actua tion module 56 possible or a choice not possible if the approach 72 in a window 164 respectively. 166 is pivoted. About this limitation, the electronic control unit or the control unit, which is not shown and preferably given, follow the circuit diagram.

The approach 72 is like 10 shows - designed so that its radially outer boundary has two parallel sections, which on opposite sides of the switching shaft 50 are arranged, and which are connected at a respective one of their ends outside via a circular arc. The facing portions of the (second) sheets 162 are also essentially flat and through the windows mentioned 164 . 166 interrupted.
