Patent ID: 8136640

Claim:
In a brake and clamping arrangement for a shaft ( 80 ) supported in a device housing ( 40 ), comprising a brake disc ( 10 ) supported rigidly on the shaft ( 80 ) for rotation therewith, the brake disc ( 10 ) having at least one friction area ( 31 ) with a truncated cone-shaped friction surface ( 32 ), and at least one brake cone ( 65 , 45 ), which is arranged in the device housing ( 40 ) adjacent the friction surface ( 32 , 47 ) and, during braking or clamping in engagement the friction surface ( 32 , 47 ), wherein for a braking or clamping loading and for a vent unloading of the brake disc ( 10 ) said at least one brake cone ( 65 , 45 ) is movable by either one of two actuating members one for movement in a loading and one for movement in an unloading direction or by a control member ( 60 ) for movement in one actuating direction and a spring system with at least one spring element ( 71 ) for movement in the other actuating direction, the improvement wherein in the device housing ( 40 ) a clamping ring ( 100 ) is non-rotatably arranged, the clamping ring ( 100 ) comprises a flange connecting area ( 111 ), an intermediate area ( 121 ) and a clamping area ( 131 ), the clamping area ( 131 ) is movable in axial direction ( 8 ) with respect to the flange connecting area ( 111 ) over the intermediate range ( 121 ) which is disposed next to the clamping area ( 131 ) and which is elastic, the clamping area ( 131 ) has an inner and an outer truncated cone shaped clamping surface ( 132 , 133 ), and the inner clamping surface ( 132 ) is arranged opposite the friction surface ( 32 ) of the brake disc ( 10 ), whereas the outer clamping surface ( 133 ) is disposed in front of the friction surface ( 69 ) of the brake cone ( 65 ).
