Patent ID: 6926126

Claim:
A disk brake assembly including a brake disc ( 20 ) and a friction brake lining ( 18 ) which can be pressed against the brake disk ( 20 ), the disk brake assembly ( 10 ) comprising a multiple brake cylinder ( 24 ) disposed laterally of the brake disk ( 20 ) movable in a secant direction of the brake disk ( 20 ), a friction brake lining piston ( 22 ) displaceably received in the multiple brake cylinder ( 24 ) transversely to the brake disk ( 20 ), the piston ( 22 ) being movable to press the friction brake lining ( 18 ) against the brake disk ( 20 ), a brake booster piston ( 26 ) received displaceably in the brake cylinder ( 24 ) in the direction of motion of the multiple brake cylinder ( 24 ) and braced against a fixed abutment ( 36 ), a closed volume between the friction brake lining piston ( 22 ) and the brake booster piston ( 26 ) and communicating therewith, a pressure transmitting medium filling the closed volume between the lining piston ( 22 ) and the booster piston ( 26 ), the multiple brake cylinder ( 24 ) being displaced along the secant direction, generally in the direction of rotation of the brake disk ( 20 ), which displacement is toward the fixed abutment ( 36 ) and causes the friction brake lining ( 18 ) to be applied against the brake disk ( 20 ), further comprising means ( 42 ) for moving the multiple brake cylinder ( 24 ) in the secant direction of the brake disk ( 20 ).
