Actuating apparatus for a friction clutch, and clutch system

A clutch system, comprising:

• a friction clutch with a force accumulator which can be loaded for clutch actuation;
• an actuating apparatus for the friction clutch, comprising:
• a first actuating element;
• a second actuating element;
• a pressure chamber delimited by the first actuating element and the second actuating element,
• wherein the second actuating element is configured for movement along a spatial axis in an actuating direction with respect to the first actuating element by introduction of a pressure medium into the pressure chamber;
• a compensation assembly;
• a rotary decoupling bearing coupled via the compensation assembly to the second actuating element for joint movement along the spatial axis,
• wherein the compensation assembly comprising:
• a first ramp element supported axially on the second actuating element and is preloaded relative to the second actuating element by a first preloading apparatus for rotation about the spatial axis;
• a second ramp element coupled to the rotary decoupling bearing for common movement along the spatial axis and is supported axially on the first ramp element, the second ramp element being non-rotating with respect to the second actuating element, and
• an axial overall length of the compensation assembly along the spatial axis changing in case of rotation, produced by way of the first preloading apparatus, of the first ramp element relative to the second actuating element;
• and
• a blocking element which is non-rotating with respect to the second actuating element and has a blocking toothing system which is in blocking engagement with a counter-blocking toothing system of the first ramp element and can be moved out of blocking engagement with the counter-blocking toothing system by way of axial movement of the blocking element along the spatial axis relative to the first ramp element,
• wherein a ratio of a spacing between the counter-blocking toothing system and the spatial axis to a base tangent length of the counter-blocking toothing system being at least 4.4;
• and
• wherein the rotary decoupling bearing being coupled to the force accumulator for selective loading of the force accumulator.
