Patent ID: 7617919

Claim:
A drivetrain for a motor vehicle, having a friction clutch for transmitting drive torque for the motor vehicle and having an actuator arrangement for actuating the friction clutch, wherein 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 a clearance which is present in the open state of the friction clutch, and 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, wherein the actuator arrangement has a first pump and a second pump which have different hydraulic transmission ratios and are directly connected to the friction clutch, the first actuator having the first pump, and the second actuator having the second pump, wherein the first pump and the second pump are driven together by one motor having a common output shaft, wherein an outlet of the first pump and an outlet of the second pump are connected to one another at a connecting point which is connected to the friction clutch, wherein a non-return valve is arranged between the first pump and the connecting point, and wherein the first pump is connected via an overrunning clutch to the output shaft.
