Block brake device of a bogie of a rail vehicle

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;
• and wherein
• 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
• an intermediate housing arranged between the two housing halves, in which intermediate housing a central pressure medium connection is constructed which supplies both cylinders of the pressure-medium operated cylinder piston drives with pressure medium.

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 at least one pressure-medium operated cylinder piston drive 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 at least one pressure-medium operated cylinder piston drive;
• the block brake device is fastened as a brake module containing at least the first and second brake beams, the pressing rods, the brake blocks and the at least one pressure-medium operated cylinder piston drive in a hanging manner by hanging lugs to the bogie;
• and
• the hanging lugs are disposed at one end side at the bogie by spherical bearings with elastically damping elements, so that they can be swivelled on all sides and are linked at another end side to the brake shoes carrying the brake blocks.
