    The invention relates to a shifting arrangement for a motor vehicle gearbox, as described in claims 1 and 2, and a gear change gear equipped with such a shifting arrangement, as described in claim 20,
    In previously known switching arrangements, the shift and selector shaft is pivotally mounted relative to the housing and / or longitudinally displaceable. The switching and Wählwelle receiving housing carries the relative to the shift and selector shaft adjustable locking elements, the locking elements exert a directed towards the shift and selector shaft radial force and submit to a connected to the shift and selector shaft ratchet. This fixedly connected to the switching and selector shaft detent body carries on its outer side facing the housing a latching contour which cooperates with the latching elements arranged in the housing. to carry out the selection and switching process. A disadvantage is that the housing for storage of the locking elements causes a high production cost and thus high production costs.
    Such a switching device for a transmission has become known for example from DE 100 02 952 B4. The switching device is used for a transmission of a motor vehicle and includes switching elements for the mechanical transfer of a desired shift from the driver via a manual shift lever and actuators to the transmission. In this case, a shift shaft relative to a transmission housing fixed axis is rotatably and slidably mounted, wherein at a rotation of the gear shafts in a Wähigasse via associated cleats a shift gate is anwähibar and with a shift of the shift shaft along the axis in a shift gate, a switching operation. Furthermore, a movable with the switching shaft locking body is provided, which has an approximately axially to and in the circumferential direction of the axis extending detent contour having portions with different radial distances from the axis and in the Schaitgassen N2010 / 24100 08/09 2010 MT 17th : 14 [SE / EM NR 5045] @ 005 17:15:03 08-09-2010 6/32 25 -2 corresponding switching contours and at least one selector contour corresponding to the selector gate. Furthermore, the switching device comprises a latching device which occurs in the region of the choice contour or a switching contour in operative connection with the latching contour, while a distance of the choice contour or a switching contour of the axis and / or inclination of the election contour or a switching contour in the contact area dependent force on the switching shaft exercises. In this case, the selection contour has an increasing distance from the axis of a first switching contour in a direction of at least one second switching contour. The second switching contour is more closely approximated to a middle contour with constant resistance than the first switching contour.
    The present invention has for its object to provide a switching arrangement and equipped with such a switching arrangement gear change transmission, in which simplifies the production of the circuit arrangement and thus the manufacturing costs can be reduced, while still a safe and proper operation for the selection and switching operation is possible.
    This object of the invention is solved by the features of claim 1. The resulting from the features of claim 1 advantage is that so by a reversal of motion of the pressure effect of the locking elements or the locking elements are coupled directly to the shift and selector shaft and these averted to the one of the switching and Wähiwetle Side directed contact force is achieved on the locking contour. By this support or support of the locking elements on the switching and selector shaft on the fixture fall in the area of the housing additional work slides for the exact processing of the previously arranged latching elements there. Thus, the housing is used only for training or recording the locking contour and can be formed from a less expensive material. This makes it possible to form the housing, for example, from a plastic material with a lower relative to a metallic cast body, specific gravity or a lower density. This not only eliminates processing costs, but it can be created even with a lower component mass, the entire switching arrangement. By applying the locking elements on the holding device so a unit is created, which merely has to be inserted into the housing and stored there. The cooperating with the locking elements detent contour is then only in or on the housing to arrange or form, so as to perform the appropriate selection and switching operation can.

    The object of the invention is, however, independently solved by the features of claim 2. The advantages resulting from the combination of features of this claim are that such a substantial simplification of the housing in its design and design can be done, since the housing only has a supporting and stocking function for the switching or selector shaft, the catch contour directly is formed on the housing or a locking body inserted in the housing. This is only to ensure a mutual, exact alignment of the locking elements and the locking contour to properly perform a corresponding dialing and shank operation can. Due to the fact that the housing only has a protective or covering function and the arrangement or design of the latching contour, a high saving potential is created here with regard to material, weight and machining effort. In most cases, only a sealing effect for the components arranged inside the housing comes about for the bearing effect.
    In the embodiment according to claim 3 is advantageous that so before each shift already a certain default for the choice of the desired gear can be done before its actual insertion. This increases the switching reliability.
    With the embodiment according to claim 4 forces can be generated in the axial direction and in the circumferential direction of the shift shaft and thus switched gears are properly locked in cooperation with the locking devices.
    Due to the design according to claim 5, it is possible to support the locking elements separately from each other on a dedicated dial or shaft contour and so to be able to perform a clear separation between the selection process and the actual switching operation. This in turn ensures a safe and proper operation of the switching arrangement. It is achieved by the staggered arrangement of the Wählkontur and the switching contour depending on the extent of the displacement, an optimal interaction between the locking elements and the two contours.
    Through the development according to claim 6, an additional simplification of the structure of the switching arrangement can be achieved. By merging the two contours in a common peripheral portion of the housing and / or the detent body, the Auslangen found only with a locking element, which is then supported both for the selection process and the Schaitvorgang to the respective contour.

    According to another embodiment variant according to claim 7 so a separate component for the formation and arrangement of the locking contour is created on this, the power transmission takes place starting from the one or more locking elements on the side facing away from the shift and selector shaft side on the inside of the detent body. This can be arranged with the least space around the shift and selector shaft of the locking body, wherein the individual locking elements are supported by the latter holding this holder adjacent thereto. By the locking body so a component is created, which can be manufactured in a separate manufacturing process and then in appropriate alignment and positioning in the switching and dial shaft receiving housing must be used. This can additionally be done to simplify the case.
    Another advantage is also a development according to claim 8, since so the locking contour forming switching and Wählkontur can be molded directly into the material of the locking body, in particular its shell parts. Additional attachments, which are joined with the shell parts, are not necessary.
    In the embodiment according to claim 9 it is advantageous that such a perfect separation of the holding device with the latching elements arranged thereon from the housing. This eliminates any Bearbeitungsauiwand the housing for holding and receiving the locking elements, whereby the desired simplification of the housing can be achieved.
    Through the development according to claim 10 it is achieved that so for the holding device, a unique fastening portion is fixed, with which this is arranged on the switching and selector shaft and held thereon. By protruding from the Befestigungsab-section holding arms so a predefined positioning of the locking elements relative to the shift and selector shaft can be done.
    Another advantage is the embodiment according to claim 11, since in conjunction with the recording with the holding arm for the locking element a clear positioning of the locking element relative to the switching and selector shaft and the locking contour can be done.
    In this case, an embodiment according to claim 12 proves advantageous, because this further simplification of the entire switching arrangement is possible. Thus, it is possible to dispense with additional storage units, whereby a further cost advantage and weight reduction can be achieved. N2010 / 24100 08/09 2010 MI 17:14 [SE / EM NR 5045] @ 008 17:15:55 08-09-2010 9/32 • «·· * · · ·» · · · * * · · · »· ···· · I · • t · · · * # -5-
    Due to the design according to claim 13 can be dispensed with additional pressure medium, since the or the Haitearme even exert the corresponding compressive force on the locking elements and this in further consequence on the locking contour. Due to the resilient elastic design of the Haitearme the installation of the switching and selector shaft can be further facilitated in the housing, since such a sufficiently large adjustment is available to put these two groups of components to the circuit arrangement can.
    A compact structure of a switching arrangement is described in claim 14. Thus, it is possible, in turn, to arrange the mounting portion of the holding device relative to the shift and selector shaft and to support and store the locking element under spring loading for generating a compressive force in the recording adjustable.
    Another advantage is the embodiment according to claim 15, wherein the holding device is a formed from thin sheet metal forming part. The holding device can be produced at low cost, especially in mass production. The consumption of material for the production of such a holding device is low. The thin sheet material allows almost unlimited designs. It can non-cutting forming processes, in particular methods for the cold forming of sheets, such as bending, pressing, embossing and dg!., Are used. The deformation of the sheet takes place in an accuracy that can be realized within narrow tolerances on form and position. Machining can usually be omitted.
    In this case, an embodiment according to claim 16 proves advantageous, because characterized arranged in a very compact design, the one or more locking elements on the switching and Wähfwelle and with respect to this the corresponding contact forces can be generated on the locking contour. Thus, one of the Schallt- and Wähfwelle pioneering pressure force is exerted on the or the locking elements. This can be done relative to the housing, in particular the locking contour formed in the housing with a small footprint and a certain centering effect of the switching and Wähiwelle.
    According to an advantageous embodiment according to claim 17 as a nearly momen tenten centering of the shift and selector shaft is achieved relative to the housing, since the elngebrachte by the locking elements on the locking contour compressive force is centered aligned with respect to the shift and selector shaft.

    But is also an embodiment according to claim 18, as such an additional component in the field of switching and Wählwelie is provided, which is used for the switching operation in conjunction with a change gear by the coaxial with the switching and selector shaft arranged barrier wall and the compound of Blocking body for switching and Wählwelie is created as a stable bearing component.
    Finally, however, an embodiment according to claim 19 is advantageous because the joints between the actuating element and the blocking wall on the one hand and the actuating element and the switching shaft on the other hand lead to a stiffening of the locking body and thus the locking body can absorb high torsional and resistive moments. As a result, the blocking body with a thin wall thickness can be formed even with high switching forces from the actuating element to a switching element (eg, shift fork or rocker arm) .The blocking body can be realized cost-effectively with simple production processes, for example stamping and bending Reliability operated and manufactured by simple means.
    The object of the invention is, however, independently solved by the features of claim 20. The advantages resulting from the combination of features of this claim are that so the switching arrangement can be easily combined with a change-speed gearbox to forward a mechanical transfer of a shift request from the driver via a manual shift lever and Steliorgane and the shift assembly to the transmission can. This can be found with a compact and cheaper version of the switching arrangement in conjunction with the change-speed gearbox Auslangen.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    In the embodiment shown here, the locking device 5 has two approximately diametrically opposite Rasteiemente 6, 7, which are fastened via a holding device 9 to the switching and selector shaft 2. Here, the locking contour 8 is arranged on the side facing away from the locking elements 6, 7 side of the shift and selector shaft 2 and the locking elements 6, 7 facing. In order to achieve a mutual concern or supporting the one or more locking elements 6, 7 on the locking contour 8, which is or are the locking elements 6.7 with a force acting in the radial direction and on the side facing away from the shift and selector shaft 2 side pressing force pressed against the locking contour 8. This is in the Fig. 3 in the region of the two locking elements 6, 7 simplified with arrows, starting from the longitudinal axis 4, shown.
    The one or more locking elements 6, 7 may be formed, for example, by mounted spherical components in order to facilitate the selection and switching operation can. The storage of the Rasteiements 6, 7 can be done by a ball bed or the like. Thus, a relative sliding or unwinding between the locking elements 6 or 7 and the locking contour 8 facing them is achieved. The choice of material for forming the locking element 6, 7 depends on the mating material of the detent contour 8 cooperating therewith. Thus, the locking element 6, 7 may be formed of a metallic material and / or of a plastic or any combination thereof. If a plastic is selected as the material, it is also possible to use aluminum or magnesium or a corresponding alloy as the material for forming the latching contour.
    By providing the holding device 9 is or, the locking elements 6, 7 are fixed and positioned relative to the shift and selector shaft 2 in their position. It can only be a relative movement of Rasteiemente 6, 7 during the selection and / or switching operation in the designated limits or adjustment with respect to the switching and Wählwefie 2 done. Thus, a first part or a first assembly of the switching arrangement 1 by the switching and selector shaft 2 and a part of the locking device 5, namely the holding device 9 with at least one of the locking elements 6, 7 is formed.
    Another assembly or a further part of the switching arrangement 1 is formed by the housing 3 and a further part of the latching device 5, namely the latching contour 8 cooperating with the latching elements 6, 7.
    The latching contour Θ in turn can be formed on a housing inner wall 10 and / or on its own detent body 11 connected to the housing 3. By this arrangement, it is now possible, the switching and selector shaft 2 together with the or N2010 / 24100 08/09 2010 MI 17:14 ISE / EM NR 5045] @ 012 25 17:17:01 08-09-2010 13 / 32

    The housing 3 may be formed either by a separate Schaltdomgehäuse or by a part of a not dargesteliten gear housing.
    3, the latching contour 8 comprises a selection contour 12 in a first peripheral section and a switching contour 13 in a second peripheral section. The selection contour 12 is preferably arranged at a distance from the switching contour 13. In this case, the Wählkontur 12 and the switching contour 13 according to the orientation of the locking elements 6r 7 to arrange or form. In the embodiment shown in FIG. 3, the locking contour 8 is formed with its selection and switching contour 12,13 on its own locking body 11, which is inserted into the housing 3 and connected thereto.
    As already described above, it would also be possible to form the Wählkontur 12 and the switching contour 13 directly to the housing inner wall 10 of the housing 3. It would also be possible, for example, only the Wählkontur 12 and / or the Schaitkontur 13 on the housing inner wall 10 of the housing 3 and form the switching contour 13 and / or the Wählkontur 12 on the locking body 11.
    If both the selection contour 12 and the switching contour 13 are provided, each of these contours 12, 13 is assigned its own detent element 6, 7 and supported on this contour or arranged adjacent thereto.
    Regardless of this, it would also be possible to combine the selection contour 12 with the switching contour 13 in a common detent contour β and to form it on a common peripheral portion of the housing 3 and / or of the detent body 11. This could be found with only one locking element 6 or 7 Auslangen, which is supported on the two contours 12,13. However, it would also be possible to assign each of the two contours 12, 13, in turn, a separate latching element 6, 7 here. The arrangement of the holding device 9 for the locking element 6 or 7 is then tuned according to the geometric conditions thereon. If one looks at the Fig. 3, then the right dargestelite switching contour 13 with its there and in a perpendicular to the longitudinal axis 4 considered cross-section wave-shaped circumferential course would also aulweisen also in the left part of Fig. 3, seen in the axial direction, kinked longitudinal course , This could be on a locking element

    In general, it should be mentioned that for the selection process before engaging a gear, the locking element 6 is in engagement with the Wählkontur 12 and is supported thereon and an axial relative displacement of the shift and selector shaft 2 relative to the housing 3 and the detent contour 8 takes place. For the implementation of the switching operation, a rotation or pivoting of the switching and selector shaft 2 takes place relative to the housing 3 about its longitudinal axis. 4
    As can now be seen further from a combination of FIGS. 1 and 3, the locking body 11 is formed by a holding device 9 with respect to the switching and selector shaft 2 at least partially circumferentially enclosing locking contour wall 14. The one or more locking elements 6, 7 are applied to the inside and the inner surface of the detent contour wall 14 facing the switching and selector shaft 2. Does the locking body 11 in the locking contour wall 14 for one of the locking elements 6, 7 an enforcement or a breakthrough, the locking element 6, 7 may be arranged in an appropriately selected switching position and / or dialing position at least partially protruding into the opening. If a separate detent body 11 is provided, the detent contour 8 can be formed in the detent body 11 forming the detent contour wall 14. In most cases, the locking body 11 is formed from a correspondingly shaped, flat-shaped blank, in particular a sheet metal.
    As already described above, in this embodiment shown here, the holding device 9 is arranged directly on the switching and selector shaft 2 or held thereon and thus arranged separately from the housing 3. The holding device 9 in turn comprises a fixing portion 15 and depending on the number of locking elements 6, 7 one or more of the mounting portion 15 projecting support arms 16, 17. In the present embodiment, two locking elements 6,7 are provided, in which case the other locking element 7 own arm 17 is assigned or the locking element 7 is supported on this. In this case, for each of the latching elements 6, 7 on the support arms 16, 17 has its own receptacle 18, 19 for the support thereof to the support arms 16, 17 are provided. The fixing portion 15 of the holding device 9 represents that portion of the holding device 9, which is fixedly and immovably arranged on the switching and selector shaft 2 and fixed thereto. The fixed connection can be made via a N2010 / 24100 08/09 2010 MT 17:14 [SE / EM NR 5045] © 014 17:17:36 08-09-2010 15/32 25 «·« · ·· * »* * ·» «« »» »· 9 ** 4 * · - 11
    Welded connection, such as a laser or inert gas welding, an adhesive bond or the like. In this case, a cohesive connection is preferred.
    In order to allow a relative displacement possibility of the or the locking elements 6, 7 during the selection and / or switching operation with respect to the latching contour 8, the holding arm 16,17 may be formed by a relative to the mounting portion 15 resilient spring tongue 20. This spring tongue 20 thus represents a connecting portion between the attachment portion 15 and the or in the receptacles 1Θ, 19 arranged locking elements 6, 7 represents.
    Regardless of this, it would also be possible to adjustably mount the one or more latching elements 6, 7 in the receptacle 16, 19 relative to this or the attachment section 15. In this case, the holding arm 16, 17 rigid and not flexible trained or can then be the holder of the locking element or 6, 7 via the receptacle 18,19 directly on the attachment portion 15.
    In this embodiment shown here, the holding device 9 is formed by a non-cutting metal punched and formed part 21.
    As already described above, the locking body 11 may be formed from a correspondingly formed without cutting punched and formed part.
    As can now be seen better from a combination of FIGS. 1 and 2, the switching arrangement 1 can also comprise a blocking element 22 fastened to the switching and selector shaft 2 as well as an actuating element 23 projecting radially beyond the blocking body 22.
    The actuating element 23 can in this case in turn be fixedly arranged on the switching and selector shaft 2 and connected to it in a fixed manner. Preferably, the arrangement of the attachment portion 15 of the holding device 9 also takes place in the region of the actuating element 23. The blocking body 22 in turn forms a coaxial with the switching and selector shaft 2 formed Spenwand 24, which circumferentially partially surrounds the switching and Wählweile 2. In the scavenging wall 24 of the locking body 22 is further provided an opening 25 which is interspersed in the mounted position of the locking body 22 on the switching and selector shaft 2 from the actuating element 23. With a corresponding, mutual, dimensional orientation of the actuating element 23 and of the opening 25, an additional support of the actuating element 23 on the blocking body 22 can be carried out.

In addition, it is also possible to connect the blocking body 22 itself to the switching and dialing world 2. This can in turn be done in a fixed position and be realized for example by an adhesive and / or welding process. Preferably, the locking body 22 is also formed from a non-cutting metal formed punching and forming part.
    As already described above, in the barrier wall 24 of the locking body 22 of the opening 25 is arranged, which is penetrated by the actuating element 23, in particular its shaft 26. For stable storage and mounting of the actuating element 23 on the switching and selector shaft 2, the actuating element 23 is connected via a stoffschlüesige joint connection in a first of the switching and selector shaft 2 facing shaft portion 27 with this. In its second shank region 28, the actuating element 23 can also be additionally connected relative to the blocking wall 24 of the blocking body 22. Thus, a two-section mounting or mounting of the actuating element 23 on the one hand on the switching and selector shaft 2 and on the other hand in the region of the opening 25 of the locking body 22 is achieved. The cohesive joint connection can be made by a welding process. Here has proven to be particularly advantageous laser welding or inert gas welding or similar distortion-free welded joints but also adhesive and solder joints advantageous. FIG. 5 shows a further embodiment of the switching arrangement 1, which may be independent of itself, and in particular a part of its detent device 5, wherein the same reference numerals or component designations are used again for the same parts as in the preceding FIGS. 1 to 4. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 4 or reference.
    In contrast to the embodiment shown in FIGS. 1 to 4 of the holder or attachment of the holding device 9 to the switching and Wählweile 2 here a clamping connection is provided instead of a material connection. This can be done by a frictional connection and / or Formschiuss. For this purpose, a separate clamping element 29 is provided in the region of the attachment portion 15, with which the attachment portion 15 of the holding device 9 relative to the shift and selector shaft 2 positionally accurately determined and can be supported. It is also still possible to form the clamping element 29 in such a way that at the mounting portion N2010 / 24100 08/09 2010 HI 17:14 [SE / EM NR 5045] ®016 17:18:10 08-09-2010 17 / 32 25 ·································································································································································································································· described actuator 23 is arranged thereon. Thus, a one-piece component can be created.
    The blocking body 22 with its blocking wall 24 can in turn have the opening 25 for receiving the shank 26 of the actuating element 23, wherein the second or further shank region 28 of the shank 26 can be connected in the region of the opening 25 to the blocking wall 24, in particular materially.
    The switching arrangement 1 described above can for example be part of a gear change transmission, in particular for a motor vehicle. In this case, the switching arrangement 1 with a switching element, not shown, in particular a shift fork or Schattschwinge the ZahnräderwechseJgetriebes cooperate and serve to transmit a selection and / or switching movement to a sliding sleeve.
    The fact that the latching device 5 is arranged with the one or more locking elements 6, 7 directly to the shift and selector shaft 2 and supported thereon, the housing 3 may be formed of a low-cost material, such as plastic. In this case, the component mass can be reduced by a lower density or a lower specific weight. In this way, in the region of the housing 3, precisely accommodating receptacles for the latching element or elements 6, 7 are eliminated and the housing 3 can be formed, for example, from a simple injection-molded component. If the housing 3 is formed of a plastic material and used in this the locking body 11, the connection between the locking body 11 and the housing 3, for example, by a thermal bonding operation and / or bonding process or the like. The positioning of the locking body 11 relative to the housing 3 can be carried out such that at least a portion of the inner wall of the housing 3 is heated to the extent that an embedding of the locking body 11 can be made in the material of the housing 3. This makes it possible to hold the locking body 11 so long in a relation to the housing 3 biased position and to be able to offset a minimum amount until the material of the softened housing 3 is again dimensionally stable. In this biased and prepositioned position of the locking body 11 is then supported relative to the housing 3 thereto.
    FIG. 6 shows a further embodiment of the switching arrangement 1, which may be independent of itself, and in particular its holding device 9, with the same reference numerals and component designations being used again for the same parts as in the preceding FIGS. 1 to 5. To avoid unnecessary repetition, N2010 / 24100 08/09 2010 MI 17:14 [SE / EM NR 5045] @ 017 17:18:28 08-09-2010 18/32 25
    Reference is made to the detailed description in the preceding Figs. 1 to 5 or reference.
    In contrast to the previously described FIGS. 1 to 5, a separate receptacle for holding the latching element or elements 6, 7 in the region of the holding device 9 is dispensed with here. The two latching elements 6, 7 shown here are designed, for example, as a spherical body and are supported the side facing away from the shift and selector shaft 2 on the locking contour 8 from. In the present embodiment, the locking contour 8 is again formed by the Wählkontur 12 and the switching contour 13. In the present embodiment, the locking body 11 carries both the Wählkontur 12 and the switching contour 13. Regardless of it would also be possible, however, the locking contour 8 in turn to the housing inner wall 10 of the housing 3 to arrange or form. Furthermore, however, the Wählkontur 12 and switching contour 13 can be formed united to the common locking contour 8.
    In this embodiment shown here, the two locking elements 6, 7 are not supported in a separate receptacle 18,19 of the holding device 9, but supported directly on the one or more holding arms 16,17 of the holding device 9 and are pressed by this to the locking contour 8 , Furthermore, the or are the two holding arms 16, 17 in one of the locking contour 8, in particular the Wählkontur 12 and switching contour 13, facing or opposite area or section with a counter-contour counterpart 30, 31 formed. Since a relative fixation of the two locking elements 6, 7 is dispensed relative to the holding device 9, can be spoken by a support of the two locking elements 6, 7 Uber on the holding arms 16,17 of the holding device 9 toward the switching and selector shaft 2.
    In order to avoid an unintentional or too far relative displacement of the locking elements 6 and / or 7 relative to the locking contour 8 and the holding arms 16,17, it is possible in the two spaces between the Wählkontur 12 and switching contour 13 and the latter facing holding arms 16 and 17 respectively at least one cage 32, 33 to arrange or provide. This serves to limit the displacement movement of the locking element 6,7. It would also be possible to provide only one of the cages 32, 33. The cage or cages 32, 33 are indicated only in simplified lines with dashed lines and are the geometric dimensions and the Relatrv movements between the support arms 16,17 and the locking contour 6 adapt. The material for forming the cage 32, 33 could also be chosen to be highly elastic, N2Q10 / 24100 08/09 2010 MI 17:14 [SE / EM NR 504S1 @ 013 25 17:18:46 08-09-2010 19/32 « »·» ··· · · * * «· ·« «* * * *» • «* * Μ ♦ - ♦ > In which case the latter participates in the relative movement starting from the shift and selector shaft 2 relative to the fixed detent contour 8. However, it would also be possible to limit the limitation of the shift paths and thus the displacement of the latching elements 6, 7 in the region of the latching contour 8, that in the region of the latching contour 8 and / or the holding arm 16, 17, a deformation of a Teilbe thereby proves An embodiment according to claim 16 advantageous because rich of the detent body 11 and / or holding arms 16,17 takes place and this formed a stop.
