  • Patent number: 8155849
    Abstract: A hydraulic actuating device (10) for an automotive friction clutch (12), has a master cylinder (14) whose master piston (16) can be impinged upon with a master force (FG) via an actuating mechanism (18) and can be displaced by a master travel (SG), and a slave cylinder (20) with a slave piston (22) which is hydraulically connected in series to the master piston via a liquid column and is functionally linked with a clutch-release member (24) of the automotive friction clutch. The actuating device may be provided with an adjusting unit (26) may have an adjusting piston (28). The adjusting piston is hydraulically connected in series to the master piston and can be impinged upon with a force and displaced via a transmission (30) that is driven by an electric motor. The actuating device further has a control unit (C) which is used to control the adjusting unit especially subject to a master variable (FG; SG).

  • Patent number: 6883658
    Abstract: A device is disclosed for the optional engaging and disengaging of a friction clutch for motor vehicles with a preferably hydraulic actuating mechanism, such as a central disengaging device, which, in order to apply an actuating force, is operatively connected with the friction clutch via at least one actuating force transmission member, such as a release bearing, which is pre-stressed in the disengaging direction by means of a spring. The device also has a sensor device with a sensor for sensing a variable representative of the engaging respectively disengaging state of and/or the state of wear on the friction clutch. According to the invention, the force of the spring for pre-stressing the actuating force transmission member or of a spring arranged in parallel with it can be sensed using the sensor, as a variable representative of the disengaging and engaging state of and/or the state of wear on the friction clutch.
