    The invention relates to a switching element, in particular a rocker arm or shift fork, a method for producing a shift element for axial displacement of a sliding sleeve and a switching device for a change-speed gearbox, as described in the preambles of claims 1,14,15 and 16.
    In gear change gears, a synchronizer body and a sliding sleeve are arranged between two gear wheels rotatably mounted on a gear shaft. The sliding sleeve is provided with an internal toothing, which engages in a synchronous body eln-provided external teeth. The synchronizer body is rotatably connected to the transmission shaft. When switching a gear, the sliding sleeve is moved in the axial direction on one of the gear wheels until their internal teeth engage in a gear wheel mounted on the coupling teeth. The internal toothing of the sliding sleeve is then engaged both with the coupling teeth and with the external toothing of the synchronizer body. The gearboxes comprise for axial displacement of the sliding sleeve switching elements, in particular shift forks or shift rockers. In this case, the switching elements mH engage arranged on the main body driving elements in a circumferential groove of the sliding sleeve, wherein a movement of the switching element is transmitted to the sliding sleeve relative to a housing.
    A shift fork is either axially displaceable mounted on a stationary switching axis or fixedly connected to this and together displaceable. Such Schaltgabefn are known for example from DE 103 60 715 A1 and DE 100 45 506 A1. ^ -υ / - * υ »ι Ό 13 f 25 • · -2-
    By contrast, a rocker arm is pivoted about an axis of rotation to move the sliding sleeve in the axial direction.
    It is also known from the prior art that the driver elements are manufactured separately from the base body and connected via additional Verbindungsseiemente fixed to the base body, for example according to DE 101 23 961 A1, DE 102 02 651 A1, DE 199 01 674 AI. DE 203 21 094U1.DE 20 2009 017 006 U1, EP 0 384 158 B1 and EP 0 878 646 A1. On the other hand, it is also known that the driver elements are formed on the base body by material deformation, for example according to DE 103 60 715 A1, DE 10 2005 035 529 A1 and EP 1 746 312 B1.
    According to EP 1 686 294 A1, the driver elements are firmly connected to each other by a driver ring, wherein the driver ring presses in the radial direction on the inside of the fork-shaped body due to a flexural rigidity in the circumferential direction of the driver elements. The driving ring firmly connected to the main body is made of plastic, aluminum or bronze,
    In generic shaft elements, the driver elements are integrally formed with a driver ring, wherein the driver ring pivotally mounted on bearing pins on the base body and a forged part or casting is. The driver ring is made of brass in most applications These known driver rings are production-related very expensive and usually require reworking on the driver elements in order to achieve the required guidance accuracy between the driver elements and the sliding sleeve. In addition, the drive ring is "solid" designed, which requires a large installation space and has a weight penalty.
    The invention has for its object to provide a switching element that has a weight advantage and can be produced inexpensively. The present invention also has the object, eh gear and a switching device to provide with such an advantageous switching element. 25 i «: w: bb / t3f | I * * * * * # *· * «*» «· · * • t * * # * * *« * * * * * * * *

    The object of the invention is achieved by the features and measures of claims 1 and 16. Between the driver elements and the base element connection levels are created by which now has the possibility to produce the base element in a separate from the driver elements manufacturing process. One can for the production of the base element of a variety of manufacturing processes, such as stamping, forming and / or injection molding technologies, use that have already proven themselves in practice and allow for mass production particularly economical production. The multi-part design of the driving ring allows a high design freedom. This allows you to react very flexibly and without complex product changes to different application requirements. The driver elements and the base element can each be connected via a non-detachable or detachable connection pivotally movable, in particular rotationally fixed. Also, the weight of the switching element can be optimized.
    The embodiment according to claim 2 is advantageous because the base element with its end sections can be connected in a particularly simple manner to the driver elements via the mounting sections. The mounting portions of the driver elements are matched to the structural design, in particular a wall thickness of the Basiseiementes.
    A particularly simple bearing function for the driver elements and high bearing accuracy of the multi-part carrier ring is achieved if the holders are produced separately from the driver elements and from the main body, in particular the shift cheeks, as described in claim 3.
    Advantageous embodiments of the invention are also described in the claims 4,5 and 17, since the brackets for adjusting a distance measure between the brackets and for its mutual alignment operation on the receiving surfaces can be positioned relative to the main body. The receiving surfaces of the main body and the mounting surfaces of the holders each have a surface dimension, wherein the surface dimension of one of the bearings 25 14: Sb: 3B ii-üt-l un 0/3 / * · «« • · · · · · · »· _4_ dimensioning and mounting surfaces is sized larger than the surface dimension of the other recording and mounting surface, so standing up the recording and mounting surfaces overlap each other. Preferably, the surface dimension of a receiving surface is greater than the surface dimension of a mounting surface of a holder. The separate production of the brackets from the body and the subsequent joining process of the brackets on the body, now allows independent of any form and / or dimensional variations of the shift cheeks exact positioning or alignment of the holding jaws. Thus, the guiding accuracy of the driver elements in the guide of the sliding sleeve significantly improves and thus the wear due to friction between the driver elements and the sliding sleeve is reduced.
    The embodiment according to claim 6 is advantageous, since the base element with its end sections can be connected in a particularly simple manner to the driver elements via the mounting sections.
    According to a possible embodiment, the mounting portions of the base member are ausgebiidet with a recess, as described in claim 7. The recess is produced for example in a chipless punching or injection molding.
    As described in claim 8, the base member is provided between the mounting portions with a guide portion, by means of which the driving ring is held in position relative to the guide of the sliding sleeve. This guide mainly serves the leadership function, but not for the transmission of switching forces and can therefore be formed thin-walled. This is associated with a weight optimization of the switching element.
    According to the embodiments according to claims 9 and 10, the base member and the Mitnehmereiemente can be rotatably connected to each other via a positive connection and / or fluid joining compound.
    Another advantage is the embodiment according to claim 11, according to which the base element is a formed from thin sheet metal without forming part The base element is to 25 44-U / -ZUI I 3Uf 25 44-U / -ZUI I 3Uf
    • * -5-low cost, especially in mass production. The consumption of material for the production of such a base element is low. The thin sheet material allows almost unlimited designs. It can non-cutting forming processes, in particular methods for cold forming of sheets, such as bending, pressing, embossing and the like., Are used. The deformation of the sheet takes place in an accuracy that can be realized within narrow position and shape tolerances of the switching elements. Machining can usually be omitted. A subsequent machining can be omitted.
    According to the embodiment according to claim 12, the base element and thus the switching element can be made easily and with low weight. A subsequent machining can be omitted.
    According to a preferred embodiment, the base body is designed in several parts, as described in claim 13. This makes it possible to produce a base body with very high dimensional and / or dimensional accuracy. In the joining process, such as beam welding, the shift cheeks and the support member are fixed in their Reiativpositionen, so that the prefabricated with high individual accuracy components can be joined to form a switching element, which over those known from the prior art switching elements with one-piece body, with far from higher Manufacturing accuracy can be produced.
    The object of the invention is also achieved by the features of claims 14 and 15. Due to the multi-part design of the driving ring, it is now possible that the driver elements are identical and can be used on all switching elements of the switching device identical driver elements and thus very little different components must be made in the production, but by connecting the driver elements yet different switching elements can be created, in a simple and cost-effective manner. Also, the switching elements with a base element in automatable process steps can be particularly easy to produce. 25 2Z-U / -Z1J11 MJ / J / ·· «· * ··· * · · · *« * »« «« «« * · · · · · · · · · · · · · · · · · ···························································· -

The driver elements 23a, 23b are pivotally connected to one another via the band-like, one-piece base member 75, in particular a connecting bracket, in particular non-rotatably. The driver elements 23a, 23b and the base member 75 are made separately from each other. The base member 75 is according to the embodiment shown a non-cutting punched and Umförmteil made of sheet metal, especially sheet steel. The Um-fbrmen preferably takes place by cold forming. The wall thickness of the base element 75, which is preferably made of sheet steel, is between 0.5 mm and 3 mm, for example 2 mm.
    The base member 30 may include in the opposite end portions mounting portions 31a, 31b, extending therebetween and a plurality of angled intermediate portion 76 and a guide portion 77. The mounting sections 31a, 31b each form a polygonal recess 78 (FIG. 12) or receptacle open on one side into which a mounting section 35 (FIG. 5) having the driver element 23a, 23b can be received in a form-fitting manner. The mounting portions 31a, 31b of the base member 75 each rigidly formed on the intermediate portion 76 integrally formed retaining arms 79 which are provided at its protruding end with a projection 80 and on their inner sides facing first abutment surfaces 81 form. Between the bearing surfaces 81, a second contact surface 82 extends. In the mounted state of the base element 75, the projections 80 engage behind the first support surface 47 and the abutment surfaces 81, 82 abut against the support surfaces 46, 47. In other words, the driving elements 23a, 23b and the base element 75 are rotatably and releasably connected to one another via the interlocking connections produced between the mounting sections 31a, 31b, 35. As shown in Fig. 12, the mounting portions 31a, 31b are wider than the intermediate portion 76.
    As is not apparent in the figures, it is also advantageous if an axial height of the mounting section 35 of the driver elements 23a, 23b is greater than a wall thickness of the base element 75 in the mounting sections 31a, 31b, whereby during assembly of the base element 75 the mounting portions 35 a particularly good guidance between the base member 75 and the driver elements 23a, 23b is achieved.
    The guide portion 77 comprises, in a guide, in particular a circumferential groove of the (not shown) sliding sleeve engaging guide body 83. The guide body 83 has, according to the embodiment shown an integrally formed from the planar guide portion 77 guide plate 84 which form at their side surfaces guide surfaces 85 , The guide portion 77 is made wider than the intermediate portion
    Also in Fig. 11 in dash-dotted lines a Führungsvomchtung for transmission elements 88,69, 70,71 (Fig. 13) entered for transmitting a switching movement. The guide device is formed on the carrier element 3 between its end regions and comprises at least two guide elements 86 extending radially with respect to the carrier element 3 at mutual axial spacing. The guide elements 86 are formed by the embodiment shown by discs, which are firmly connected to the support member 3, for example, a substance-liquid joint connection.
    In Fig. 13, a switching device 65 described in AT 1327/2010 and subject of this disclosure is a manually shiftable one... 15:05:34 ^ -u / - ^ un i tu
    Motor vehicle change gear shown, which has multiple grades and is designed in this embodiment for a 5-speed change gear. The shading device 65 comprises a first shifting element 66 for axial displacement of a first sliding sleeve (not shown), a second shifting element 67 for axial displacement of a second sliding sleeve (not shown) and the shifting elements 66, 67 pivotally interconnecting transmission elements 68, 69, 70, 71 and a shift and selector shaft 72. With the first shift element 66 and the transmission element 70 can be changed between the first and second gear. With the second shade element 67 and the transmission element 69 can be changed between the third and fourth gear. With the transmission element 68, a fifth gear and with the transmission element 71, a reverse gear (R) can be selected. The shift and Wählwelie 72 is rotatable about its longitudinal axis (switching movement) and displaceable in the axial direction (selector movement) mounted in a gear housing, not shown, and has at least one attached thereto actuating element 73, in particular a shift finger. The Übertragungsseiemen te 68.69,70,71 are each provided with a recess which is limited at least in sections by locking and buttons.
    In cooperation with the actuating element 73, either one of the transmission elements 68,69,70,71 can be acted upon by a switching force by the actuator 73 initially shifted by a selection movement of the switching and selector shaft 72 in the axial direction in a aligned with one of the recesses Wähllebene and thereafter rotated by a switching movement of the shift and selector shaft 72 about its longitudinal axis. In this case, the actuating element 73 runs against one of the buttons of a transmission element 68,69,70, 71 and switches a gear.
    As shown in this figure, now the switching element 66 and / or the switching element 67 with the base element 30 described above; 57; 75 are equipped. 25 15:06:16 22-U / -2U11 22 13 / -18-
    As can be seen from the figures to the different embodiments, the connecting planes extend between the left-hand driver element 23a and the base member 30; 57; 75 and the right driver element 23b and the base member 30; 57; 75 parallel to the contact surface 44 of the driver elements 23a, 23b. In this case, the contact surface 44 extends perpendicular to the bearing axis 24 (pivot axis) of the driver elements 23a, 23b. Preferably, the mounting portions 31a, 31b of the base member 30; 57; 75 respectively against the abutment surface 44 of the driver elements 23a, 23b, and thus an axial positioning of the base member 30; 57; 75 opposite the driver elements 23a, 23b achieved. The radial positioning of the base member 30; 57; 75 with respect to the driver elements 23a, 23b by the connection between the mounting portions 31a, 31b; 58a, 58b, 35 reached.
    Finally, it should be mentioned that the main body can also be integrally formed by a sheet metal forming part according to another embodiment. Contrary to the embodiment shown, the switching element can just as well be designed by a shift fork which is either axially slidably mounted on a stationary shadow axis, as disclosed for example in AT 508 130 A4, or firmly connected to this and be jointly sam be displaced, such as disclosed in DE 100 45 506 A1. According to this embodiment, the shift movement of the shift element in the shift direction is a linear shift movement, whereas, in the shifting rock described above, the shift movement in the shift direction is a pivoting movement.
    For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the switching element 1, these or their components have been shown partly unevenly and / or enlarged and / or reduced in size.
    Above all, the individual embodiments shown in FIGS. 1 to 13 can form the subject of independent solutions according to the invention. 25 ΐϊ: υ »: ιυ ζζ-υ / - ^ υ 11 α (3 / ρ · · ψ - • / ν '-
