Embodiment Construction

[0047] figure 1 The control circuit of the first variant of the invention is shown schematically figure 1 .

[0048] control line figure 1In this example there are three channels 2, 3, 4 for transmission and clutch operation. In this case, the channels 2 , 3 , 4 are formed substantially rectilinearly and are arranged parallel to one another. The control points for gear stages and clutches are located at end positions 5, 6, 7, 8, 9 of channels 2, 3, 4. In this example channels 2 and 3 are used for the gear stages and channel 4 is used for the clutch. In this case, the control points are bent or oriented offset to one side from the straight line of the channels 2 , 3 , 4 .

[0049] exist figure 1 , the gear stages are indicated by the numbers 1, 3, 5 and 7, because in figure 1 An example of a control circuit diagram for a sub-transmission with odd gears is shown in .

Abstract

The invention relates to an operating device, in particular for selecting and / or operating gear stages of a transmission and / or for engaging and disengaging clutches of a motor vehicle, with a control circuit diagram, with a plurality of guide rails, which are operatively connected to operating elements, wherein A guide track for engaging or disengaging a transmission stage and / or for engaging or disengaging a clutch, wherein the corresponding actuation is controlled when a specific position of the guide track is reached, wherein the guide track is achieved by moving in at least one defined transition track changes.

Description

technical field [0001] The invention relates to an actuating device, in particular for a dual clutch transmission with two partial clutches of a motor vehicle. Background technique [0002] In motor vehicle transmissions, the rotational speed change between the transmission input shaft and the transmission output shaft is formed by a gear pair. A spur gear transmission is known here as an example. Here, the shifting of the transmission takes place via a shift mechanism in the transmission. In a manually shifted transmission, the shifting mechanism is connected to a gear lever via a connecting rod or a pull cable, and the gear stage can be selected and switched via the gear lever. [0003] In automatic transmissions, the shift mechanism is actuated by means of an operating device which has an actuator for selecting a gear stage and an actuator for engaging or disengaging a gear stage. [0004] In the aforementioned spur gear transmission, the drive motor of the motor vehic...
