  • Publication number: 20130032444
    Abstract: A method for controlling an automated clutch (10) that is actuated by a hydraulic clutch actuating system including a hydrostatic actuator (19) whose pressure is detected, comprising the step of using the detected pressure of the hydrostatic actuator (19) to detect and avoid undesired overloading of the actuator (19), of the clutch, and/or of at least one auxiliary device associated with the clutch (10) or with the actuator (19).

  • Publication number: 20130025999
    Abstract: The invention relates to a method for operating an automated clutch of a motor vehicle, which is operated using a hydrostatic actuator of a hydraulic clutch operating system, which includes a slave cylinder and a master cylinder that contain hydraulic medium, a volume equalization of the hydraulic medium being carried out in a driving operation in order to counteract a detuning of the clutch operating system. The invention is distinguished by the fact that the volume equalization is carried out as needed during operation of the clutch depending on current clutch characteristic values, if the driving comfort is not, or not inappropriately, diminished.

  • Publication number: 20130025996
    Abstract: The invention relates to a method for controlling a dual clutch and a dual clutch housing two friction clutches which are each actuated independently of one another by means of a hydrostatic actuator. The hydrostatic actuator actuates the clutch as a function of a control signal of a control unit by means of a pressure which is applied to the actuation element and corresponds to a position of an actuation element of the friction clutch along an activation path. In order to sense a change in the position of the actuation element on one friction clutch which is brought about by the pressure on the actuation element of the other friction clutch, it is proposed to determine a correction variation for the purpose of compensating the changed position by means of a variable which represents the pressure of the disruptive hydrostatic actuator.

  • Publication number: 20130025995
    Abstract: A dual clutch having a first transmission-side output shaft and/or a second transmission-side output shaft having a first clutch comprising a first pressure plate that is axially movable relative to a first counterplate for engaging a first clutch disk connected to a first output shaft, a second clutch comprising a second pressure plate that is axially movable relative to a second counterplate for engaging a second clutch disk connected to a second output shaft, an actuating device for moving the first pressure plate and/or the second pressure plate and a fastening plate connected to the actuation device for axially fastening to a clutch housing, wherein the actuating device is designed to pre-center relative to the clutch housing and/or the transmission housing in a radially adjustable manner, and the fastening plate is designed to be radially fixed to the clutch housing and/or the transmission housing.

  • Publication number: 20130024081
    Abstract: A method of operating a double clutch that is actuated by a hydrostatic actuating system having two clutch actuators assigned to two individual clutches and each clutch actuator including a pressure sensor for sensing the operating pressure of the respective clutch actuator, the method having the step of limiting a total actuating force of the double clutch in the event of a fault using the pressure values sensed by the pressure sensors.

  • Publication number: 20130020167
    Abstract: A dual clutch having a first clutch which has a first pressure plate that is movable axially relative to a first counterplate for coupling a first clutch disk that is connected to a first output shaft, a second clutch, which has a second pressure plate that is axially movable relative to a second counterplate for coupling a second clutch disk that is connected to a second output shaft, a torsional vibration damper situated in the direction of flux force between the input shaft and the first counterplate wherein the torsional vibration damper includes a dual mass flywheel with a bow spring running in the circumferential direction to transmit torque, where the flux of force is introducible radially on the outside from the input shaft to the first counterplate into the dual mass flywheel, and is dispersible radially on the inside to the bow spring.
