Abstract
A clutch unit for a motor vehicle comprises a friction clutch and an actuator for actuating the friction clutch, the actuator having a first ramp ring and a second ramp ring, of which at least one can be rotated relative to the other ramp ring, in order to exert an axial force on the friction clutch. Furthermore, the clutch unit comprises a metering device for feeding a cooling fluid in a metered manner to the friction clutch. The metering device has a first metering section which is assigned to the first ramp ring, and a second metering section which is assigned to the second ramp ring, the first metering section and the second metering section together delimiting a metering opening for the cooling fluid. The first metering section and the second metering section interact in such a way that the cross section of the metering opening, which cross section is delimited by the metering sections, can be varied by way of a relative rotation of the ramp rings.
