    摘要: A friction clutch (10) in particular for a vehicle comprises at least one clutch disc (14, 16) and a compression plate (20), an activation spring (24) having a first position in which the activation spring (24) is disengaged from the compression plate (20) and a second position in which the activation spring (24) biases the compression plate (20) against the clutch disc (14, 16), and a bistable positioning mechanism (30) adapted for holding the activation spring (24) in the first position, the bistable positioning mechanism (30) having a first and a second configuration in which the bistable positioning mechanism (30) has different lengths in axial direction, the bistable positioning mechanism (30) comprising a cog sleeve (34) having a plurality of corrugations (36) and a cam sleeve (38) having at least one cam surface (40), wherein the cog sleeve (34) has a fixed position in axial direction and the cam sleeve (38) has first and second sets of indentations (42, 44) in the cam surface (40) at different positions in axial direction in which the plurality of corrugations (36) of the cog sleeve (34) can be form-fittingly received, and a switching sleeve (48) having a plurality of switching corrugations (50), wherein the switching sleeve (48) is movable in axial direction and an axial movement of the switching sleeve (48) pushes the switching corrugations (50) of the switching sleeve (48) against the cam surface (40) of the cam sleeve (38), causing a relative movement in axial and circumferential direction between the cam sleeve (38) and the cog sleeve (34), moving the corrugations (36) of the cog sleeve (34) between the first and second set of cam surface sections (42, 44).
