  • Patent number: 8628452
    Abstract: A method is provided for controlling an output torque of an automated transmission coupled to an internal combustion engine and having a transmission controller. The internal combustion engine includes an exhaust gas turbocharger and an injection air device for injecting air into an intake line. The method receives a torque requirement by the transmission controller, generates an injection air signal by the transmission controller based on the torque requirement and current operating parameters of the internal combustion engine and the automated transmission, and controls the output torque by activating the injection air device based on the injection air signal for injecting air into the intake line of the internal combustion engine for a duration to be determined. A corresponding device is provided for carrying out the method.

  • Patent number: 8157073
    Abstract: A separable clutch for a motor vehicle has a clutch plate including a moveably mounted release unit. The clutch is pressure-medium actuated and includes an actuating piston acting on the release unit to engage and disengage the clutch, and a pressure chamber which is delimited at one side by at least one part of the actuating piston and at the other side by at least one part of a clamping piston. At least the actuating piston, the pressure chamber and the clamping piston are resiliently supported in a defined position against the release unit by spring force. The spring force is smaller than a limit force required for actuating the release unit. A pressure change in the pressure chamber, brought about by a clutch actuation causes the clamping piston to actuate a clamping device such that the clamping piston is fixed before the actuating piston actuates the release unit.
