Patent ID: 7165659

Claim:
A block brake device of a bogie of a rail vehicle containing two wheel sets with two wheels, respectively, the block brake device comprising: a first and a second brake beam each assigned to a wheel axle and extending parallel to the wheel axle, which brake beams carry brake blocks and are mutually connected by pressing rods which can be actuated by two pressure-medium operated cylinder piston drives for the braking engagement of the brake blocks with assigned braking areas of the wheels; at least a portion of the first brake beam forms a cylinder of the two pressure-medium operated cylinder piston drives; a cylinder face of the cylinder is formed by one of an inner circumferential surface of the wall of the first brake beam and a cylinder lining carried by the wall; the two pressure-medium operated cylinder piston drives are coaxial and operate in opposite directions and are integrated in the first brake beam; the first brake beam has two identically constructed housing halves which can be symmetrical with respect to a center plane of the bogie and which, at least in sections, form the cylinders of the two pressure-medium operated cylinder piston drives; and one deflection gearing for deflecting piston movement to the pressing rods is accommodated in an encapsulated manner in the housing halves.
