Abstract

A clutch arrangement for a drivetrain of a motor vehicle. The clutch arrangement has a first clutch, a second clutch, and a hydraulic actuator arrangement. The actuator arrangement has a first hydraulic cylinder for actuating the first clutch and a second hydraulic cylinder for actuating the second clutch. The actuator arrangement has an actuator pump which is driven by means of an electric motor and which can be operated in two directions of rotation. The actuator pump has a first port, which is connected to the first hydraulic cylinder, and a second port, which is connected to the second hydraulic cylinder. The actuator arrangement actuates the first or the second clutch depending on the direction of rotation of the actuator pump.
