Dual clutch and method for controlling the same

A dual clutch in a drive train of a motor vehicle, which has an internal combustion engine with a crankshaft and a dual clutch transmission with transmission input shafts, the dual clutch comprising:

• two friction clutches, a first friction clutch and a second friction clutch, which transmit a torque from the internal combustion engine to the transmission input shafts of the dual clutch transmission;
• a common counterpressure plate firmly connected to the crankshaft of the internal combustion engine;
• a housing component firmly connected to the counterpressure plate;
• lever springs, which actuate the friction clutches, supported on the housing component;
• and
• two contact plates, which are fixed in terms of rotation relative to the counterpressure plate and can be moved axially by means of the lever springs,
• wherein the lever springs are actuated radially in a same direction by actuating systems in a case of a change from one friction clutch to the other for torque to be transmitted via the friction clutches.

A method for controlling two actuating systems for actuating a dual clutch in a drive train of a motor vehicle, which has an internal combustion engine with a crankshaft and a dual clutch transmission with transmission input shafts where the dual clutch comprises two friction clutches, a first friction clutch and a second friction clutch, which transmit a torque from the internal combustion engine to the transmission input shafts of the dual clutch transmission;

• a common counterpressure plate firmly connected to the crankshaft of the internal combustion engine;
• a housing component firmly connected to the counterpressure plate;
• lever springs, which actuate the friction clutches, supported on the housing component;
• and two contact plates, which are fixed in terms of rotation relative to the counterpressure plate and can be moved axially by means of the lever springs, wherein the lever springs are actuated radially in a same direction by actuating systems in a case of a change from one friction clutch to the other for torque to be transmitted via the friction clutches, the method comprising the steps of:
• prioritizing a first actuating path of a first actuating system;
• and
• excluding an interference with the first actuating path by a second actuating path of the second actuating system.
