Abstract

A clutch arrangement for a drivetrain of a vehicle comprises a first friction surface, a second friction surface, a pressing element and a sealing element. The second friction surface is coupled to an output component of the clutch arrangement to be substantially fixed with respect to rotation relative to the output component. The first and second friction surfaces are configured and arranged to be brought into frictional engagement with each other to make a torque transmittable from the first friction surface to the second friction surface. The first and second friction surfaces are further configured to be exposed to a fluid medium. The pressing element is configured to produce or sever the frictional engagement by causing a force along a force direction when actuated. The sealing element is configured to separate a first volume in which the first and second friction surfaces are arranged from a second volume.
