Braking and/or clamping device having an actuation assembly and a shaft-coupling assembly II

A braking and/or clamping device for a shaft guided in relation to a main body, comprising

• an actuation assembly and
• a shaft-coupling assembly,
• wherein the actuation assembly comprises a gap housing, which has a mounting zone and
• a bending zone which is elastically deformable in some regions with two bending plates separated by a gap,
• wherein the bending plates each comprise in two opposing clamping zones tong jaws having friction surfaces, respective surface normals of which are directed inwards,
• wherein a sealed pressure chamber, which can be filled with a pressure medium for elastically pushing apart the friction surfaces, is arranged between the bending plates,
• wherein the shaft-coupling assembly comprises a clutch region which has two friction surfaces spaced apart from each other, respective surface normals of which point outward,
• wherein the shaft-coupling assembly comprises a shaft-coupling region,
• wherein the shaft-coupling region is arranged either directly or indirectly via a clamping mechanism on the clutch region, and
• wherein when the sealed pressure chamber is relieved of pressure, the friction surfaces of the actuation assembly can be applied to the friction surfaces of the shaft-coupling assembly, thereby producing a braking and/or clamping force.
