ABSTRACT:
A drivetrain for a motor vehicle has a friction clutch for transmitting drive torque for the motor vehicle and has an actuator arrangement for actuating the friction clutch. The actuator arrangement has a first actuator which is designed to close the friction clutch quickly with little force expenditure in order to thus quickly close up the play which is present in the open state of the friction clutch. The actuator arrangement has a second actuator which is designed such that, with a small stroke, it applies a large force for actuating the friction clutch in order to keep the friction clutch closed with little energy expenditure.
