Patent ID: 8469157

Claim:
A brake assembly, comprising an intermediate part ( 13 ), arranged between a control member ( 11 ) and a brake element ( 12 ) and wherein a first coupling ( 14 ) is arranged between the control member ( 11 ) and the intermediate part ( 13 ) and a second coupling is arranged between the intermediate part ( 13 ) and the brake element ( 12 ), said brake assembly being applied by movement of the control member ( 11 ) towards the brake element ( 12 ) wherein a brake clearance restoring unit ( 2 ) is arranged inside a recess in the intermediate part ( 13 ), the restoring unit being connected with the control member ( 11 ) and brake element ( 12 ) by friction gripping devices ( 15 , 15 ′) housed in a recess in the control member ( 11 ) and brake element ( 12 ) respectively, the connections between the restoring unit and the control member ( 11 ) and brake element ( 12 ) respectively allowing the control member ( 11 ) to move towards the intermediate part ( 13 ) during application of the brake by a first predetermined brake clearance ( 24 ) to compress the restoring unit ( 2 ) and the intermediate part ( 13 ) to move towards the brake element ( 12 ) by a second predetermined brake clearance( 24 ′) to compress the restoring unit ( 2 ) without the friction gripping devices ( 15 , 15 ′) slipping relative to the control member ( 11 ) and brake element ( 12 ) respectively, the restoring unit moving the control member ( 11 ) and brake element ( 12 ) away from the intermediate part ( 13 ) to re-establish the brake clearances ( 24 , 24 ′) when the brake is released.
