Embodiment Construction

[0019] figure 1 In simplified schematic form, two gear selectors 10 , 12 are shown, which actuate shift sliders 14 , 16 , 18 arranged in a dual-clutch transmission (not shown). The selector slides 14 , 16 , 18 are connected in a known manner, for example directly via a selector fork 20 , to the synchronizing clutches of the shiftable gear sets. However, it is also possible for the selector slide to act via a carrier on the selector lever, the subsequent selector slide, etc.

[0020] For example, shifting from the neutral position N into the reverse gear R is possible via the selector rod 14 by means of the adjusting piston of the gear shifter 10 , which is hydraulically actuated, for example, via the transmission control unit.

[0021] Via the second shift slide 16 next to the first shift slide 14, it is possible to shift from neutral, for example, to the sixth (6) or eighth (8) forward gear of the dual clutch transmission via the same gear selector 10 .

[0022] The select...

Abstract

A shift device for dual-clutch transmissions in motor vehicles, having a plurality of forward gears and one reverse gear, in which the shift rails which act on synchronizing clutches of the shiftable gearwheel sets are actuated, in accordance with the commands of an electronic transmission controller, by means of hydraulically or electrically operated gear actuators for automatic gear shifting. To obtain a structurally and functionally simpler shift device, it is proposed that a switchover device (22) is provided on two adjacently arranged shift rails (14, 16), by means of which switchover device selectively one or the other shift rail (14, 16) can be coupled to a common gear actuator (10).

Description

technical field [0001] The invention relates to a shifting device for a dual clutch transmission in a motor vehicle. Background technique [0002] This type of dual-clutch transmission mainly has the advantage of being able to change gears without interrupting the tractive force, where a forward gear is engaged and activated by means of one of the clutches, while the second forward gear can already be preselected. Then, by transition-free shifting between the two clutches, a preselected forward gear can be activated and so on. However, switching devices such as those described in EP 0615081 A1, in which one servomotor triggers the preselection in the switching channel and the second servomotor triggers the gear shift, cannot be used in these transmissions. As mentioned above, both handover procedures cannot be implemented at the same time. [0003] It is therefore necessary to provide a hydraulically or electrically operated gear adjuster for each of the shift rods / fork sh...
