    The present invention relates to a switching device for a change-speed gearbox, in particular for automatic dual-clutch transmission, according to the preamble of patent claim 1, and a method for performing switching operations according to the preamble of claim 25.
    Such automated manual or dual-clutch transmissions have u.a. the advantage that they are switchable without interrupting the traction, with a forward gear engaged and activated by means of a disconnect clutch and a second forward gear can already be selected. By seamlessly changing the two disconnect clutches, the preselected forward gear can then be activated, etc. However, in these transmissions, no switching device, e.g. as described in EP 0 615 081 A1, in which a servomotor preselects in a shift gate and a second servomotor triggers the gear shift. Both switching operations (switching and preselecting) as stated above are not feasible.
    It is therefore necessary to provide each shift rail for the various gears including the reverse gear a hydraulically or electrically operated gear splitter.
    The object of the invention is to provide a switching device, in particular for a dual-clutch transmission of the generic type, which is structurally and control-technically simpler and, accordingly, less expensive. Furthermore, a method for performing the Schattvorgärtge will be shown. N2011 / 26900 D ΠΠΕ / Λ07

    The object is solved by the features of claim 1 or claim 25 Advantageous and particularly expedient developments of the invention are the subject of the dependent claims.
    According to the invention, the switching device comprises inter alia first to fourth switching axes. Between the first and the second switching axis, a first transmission unit is interposed with this, a first switching movement between the first switching axis and the second Schaitachse be transmitted. In addition, a second Übertragungsseinheft is provided, with which a further switching movement between the second switching axis and one of the third and fourth switching axis is transferable According to the characterizing part of claim 1, the second Obertragungseinheit comprises a shift finger, which on the second switching axis between one of the engagement positions with a the third and fourth switching axis is pivotally mounted
    These features make it possible to couple the third or fourth shadow axis depending on the first Schaitachse to a common gear plate, whereby the structural and control engineering effort can be reduced.
    In a preferred embodiment, one of the shadow axes may be designed as a shift rod which is connected to the common gear actuator. The other switching axes, however, can be designed as a shift rails. The shift rails are known to operate via shift forks on synchronizer clutches of gear sets for forward gears and a reverse gear and are operated via controlled by a transmission control gear selector. When applying the invention to this embodiment, the first transmission unit is arranged between a first Schaitschfene and the shift rod. Between the shift rod and a second and a third shift rail, the second transmission unit is arranged. The second transmission unit has the above-mentioned shift finger, which is umschattbar via the first transmission unit alternately in an engaged position with the second shift rail or the third shift rail. The following examples of the invention are with reference to this particular embodiment. In the following, the invention is to be understood described. It is understood, however, that the invention is not limited to this embodiment.
    The coupling elements and transmission elements on the transmission units may preferably be formed by shift paddles and shift gates, as described in the subclaims. In addition to a production-engineering and assembly-technically favorable design, these provide a reliable function of the switching operations despite the gearbox-related linking of several shift rails. For details, reference is made to the subclaims and the description.
    Finally, claims 25 and 26 describe a preferred method for performing such associated shifting operations, in which the shifting movement of a first shift rail is transmitted via a first transfer unit and a second transfer belt on a shift rail of a common speed divider of the transmission such that its shift finger between one of the engaged positions is pivoted with a second and a third rail rail.
    Two embodiments of the invention are described in more detail below with further details. Show it:

    Fig. 1 shows a switching device 10 for a dual-clutch transmission (not shown) for motor vehicles of known type, e.g. with eight gear sets for forward gears and a reverse gear set, which can be switched via synchromesh clutches. The switching device 10 has inter alia first to value switching axes 18,24,20,22. Of these, the switching axes 18, 20,22 are each designed as shift rails. The switching axis 24 is embodied in FIG. 1 as a switching rod which is actively used with a gear splitter, the mode of operation of which will be described later.
    The above-mentioned shift rails carry shift forks (generally designated 12) and are spatially distributed in the transmission housing, not shown, and stored axially displaceable or rotatable (shift rail 22). The shift rails engage the synchronizer clutches of the gear sets in a known manner and shift them from a neutral position (no gear engaged)

    f. «* * * ·· * · Va · · · · ·« * • · »· · · · · · · · · · nt · * · · ·» The shift rails 14, 16, 18 are actuated by means of hydraulic or electromagnetic gear actuators (with corresponding actuating pistons, etc., not shown) which directly engage the slidably mounted shadow rails 14, 16, 18.
    The dual-clutch transmission is divided in a known manner into two partial transmissions, one of which has the straight forward gears (1, 3, 5, 7) and the other the odd forward gears (2, 4, 6, 8) and which can be activated via two separating clutches. Corresponding to the function of dual-clutch transmissions, it is thus possible in a forward gear, e.g. the 5th gear, with the disconnect clutch of the other subgear open, the sixth forward gear can be selected and activated by closing this disconnect clutch and simultaneously opening the other disconnect clutch without interrupting the traction, etc.
    However, this function requires that the shift rails 14 to 22 for the eight forward gears and reverse must be separately switchable, which would require five gear shifter.
    In order to avoid this, a gear selector with a sound bar 24 is arranged on the switching device 10 so as to be axially displaceable, wherein the switching rod 24 is coupled via a first transmission unit 26 to the shift rail 18 and via a second transmission unit 28 with a radially projecting shift finger 34b Depending on the position of the shift rail 18, the shift rail 20 or the shift rail 22 with the shift rod 24 and the corresponding gear plate coupled.
    In the exemplary embodiment, the fifth and seventh forward gear, via the shift rail 20 of the sixth and eighth forward gear and the shift rail 22 with the reversing lever 22a of the reverse gear of the dual clutch transmission is connected via the Schaitschiene 18.
    The shift rod 24 (see Fig. 2 and 3), at the free end 24a of the gear plate engages, is axially displaceably mounted in a support member 32 with a mounting flange 32a (or in the gear housing). The support element 32 is not in 17/02/2012 09:41

    The shift rod 24 carries a rotatable, but axially unmovable held sleeve 34 to which a radially projecting, axially parallel bar 34a is attached as a coupling element, which interact with two guide rollers 36a as adjusting elements with a switching rocker 36.
    The rocker switch 36 is mounted on the support element 32 via a pivot axis 36 which is oriented perpendicular to the shift rod 36 and has an extension 36b projecting towards the shift rail 18, which projects into a fork-shaped recess of a driver 40 arranged on the shift rail 18 as a further coupling element
    From the sleeve 34 on the other hand protrudes a shift finger 34b in the radial direction, which extends through a shift gate 42a (Fig. 3) attached to the support member 32 tab 42 and with fork-shaped dogs 44,46 on the shift rail 20 and the lever 22a of the Switching rail 22 cooperates.
    The axially projecting into the recess of the shift gate 42a web 42aa stiffens sure that the shift finger 34b can be moved axially above the gear plate and the shift rod 24 only when the shift finger 34b either with the driver 46 or the driver 44 is engaged, ie not both drivers 46, 44 can operate simultaneously.
    The interaction of the transmission units 26,28 with the common gear actuator and the shift rod 24 is as follows
    If the shading rail 18 is in the middle neutral position (drawn in FIG. 2), the guide rails 36a of the rocker switch 36 are in an axially parallel alignment, and the sleeve 34 with the rail 34a as the coupling element is in a position in which the shift finger 34b is in engagement with the driver 46 of the shift rail 22. Thus, by activating the gear selector via the non-illustrated electro-hydraulic transmission control and by axially displacing the shaft rod 24, the reverse gear can be switched.

    If the shift rail 18 for shifting or preselecting the fifth or seventh forward gear on the attacking at 18a gear shift axially out of the neutral position out, so the switching rocker 36 is pivoted via the coupling element or the driver 40 and the extension 36b, wherein one of Führungsroilen 36a, the sleeve 34 is rotated over the radially projecting bar 34a on the shift rod 24 and the shift finger 34b now with the driver 44 engages. Accordingly, the shift rail 20 can be switched for the sixth or eighth forward gear via the common gear plate and the shift rod 24.
    Between the shift rod 24 and the relatively rotatable sleeve 34, a wrap spring 48 is inserted, which biases the sleeve 34 with the bar 34a against the rocker switch 36 and the guide rollers 36a.
    4 to 6 show an alternative switching device 10 ', which is described to avoid repetition only to the extent that it differs significantly from the shank device 10 according to FIGS. 1 to 3. Functionally identical parts are provided with the same reference numerals.
    In this case, on the support member 32 'on a downwardly projecting arm 32b via a parallel to the shift rod 24 aligned pivot axis 50 mounted rocker switch 52 two diametrically opposed guide lugs 52a, 52b as coupling elements on the one hand in a shift gate 54a (Fig Stelletements 54 on the shift rail 16 and on the other hand in a trained on the sleeve 34 Schaltkulisse 56 (Fig. 7) protrude.
    The shift finger 34b projecting radially from the sleeve 34 in turn extends through the camshaft 42a of the lens barrel 42 and can be coupled either to the cam 46 of the shift rail 22 or its reversing lever 22a or to the cam 44 of the shift rail 20.
    Accordingly, the switching rocker 52 forms with the guide lugs 52a, 52b and the shift gate 54a of the actuating element 54 and the shift gate 56 on the sleeve 34, a transmission unit 26 and the shift finger 34b with the N2011 / 25800 Μ - DAf7 D Ai 1 / Λ07 25 09:41:37 17-02-2012 25 12/27
    8 mem 46,44 the other transmission unit 28, as described above, a common gear plate with shift rod 24 for the two shift rails 20, 22 allow.
    The function of the coupling of the two shift rails 20,22 to the common gear plate with shift rod 24 is substantially as described above. However, the rotation of the sleeve 34 for adjusting the shadow finger 34b within the shift gate 42a is controlled as follows:
    The shift gate 54a on the shift rail 18 (see Fig. 6) is approximately wave-shaped with an elevation (central neutral position) and two circumferentially offset, viewed in plan view recessed ends, in which the guide lug 52a of the rocker 52 projects.
    If the shift rail 18 is displaced axially, the rocker switch 52 is pivoted accordingly and rotated via the shift gate 56 and the projecting guide lug 52b, the sleeve 34 relative to the shift 24 such that in the neutral position of the shift rail 18 of the shift finger 34b in the driver 46 and at a switched or preselected forward gear 5 or 7 protrudes into the driver 44 of the shading rails 22,20.
    The shift gate 56 (FIG. 7) has two window-like, circumferentially extending and axially mutually distanced recesses 56a, which are interconnected by a connecting slot 56b at the upper edge region. In the neutral position of the shift rod 24, the guide projection 52b is in the region of the connecting slot 56b and can shade the shift finger 34b correspondingly by turning the sleeve 34 in the case of a shadow movement of the shift rail 16.
    By contrast, is srcher-abgestettt through the window-like recesses in the circumferential direction that switched over the gear plate with a shunt rod 24 or preselected forward gear shift rail 18 and the rocker switch 52 is decoupled as a transmission element of the shift gate 56, so can be switched.
