Abstract:
1. A clutch arrangement for a drivetrain of a vehicle, comprising: a first friction surface and a second friction surface that are arranged to be movable relative to each other along an axis of rotation of the clutch arrangement, wherein the first and second friction surfaces are formed in a way that they can be brought into a frictional engagement with each other to make a torque transmittable from the first friction surface to the second friction surface, and wherein one of the first friction surface and the second friction surface is arranged at a component part; and a pressing element comprising a spring structure and configured to produce or sever the frictional engagement upon actuation by causing a force along the axis of rotation, wherein the spring structure is configured and arranged to at least partially cause the force on the component part through a change in shape, the pressing element further comprises a pressing structure that is formed such that the pressing structure limits a change in shape of the spring structure, and the spring structure and the pressing structure are formed such that the spring structure substantially completely transmits the force to the component part when the pressing structure limits the change in shape of the spring structure.
