Abstract
The invention relates to a braking system of a rail vehicle, particularly of a railroad freight car, containing a parking brake device having a gearing which converts a rotating movement initiated by rotation-actuating devices to an application movement of at least one pressure-medium-operated cylinder piston drive. The invention provides that at least one universal-joint shaft (30) connecting the rotation actuating devices with a gearing input of a toothed gearing (12) arranged in the direct vicinity of the cylinder piston drive (10) is provided, as well as a nut screw drive (62) which converts the rotating movement at a gearing output (36) of the toothed gearing (12) to a linear movement of a piston (46) of the cylinder piston drive (10).
Claims26
Braking system of a rail vehicle, particularly of a railroad freight car, containing a parking brake device having a gearing which converts a rotating movement initiated by rotation-actuating devices to an application movement of at least one pressure-medium-operated cylinder piston drive,
- characterized in that at least one universal-joint shaft (22, 30;
- 86;
- 108′) connecting the rotation actuating devices with a gearing input of a toothed gearing (12;
- 116′) arranged in the direct vicinity of the cylinder piston drive (10;
- 20a′, 20b′) is provided, as well as a nut screw drive (62;
- 102′) which converts the rotating movement at a gearing output (36, 122′) of the toothed gearing (12;
- 116′) to a linear movement of a piston (46;
- 88;
- 74a′, 74b′) of the cylinder piston drive (10;
- 20a′, 20b′).
Braking system according to one of the preceding claims,
- characterized in that it is constructed as a brake module fastened by means of hanging lugs (18′) to a bogie (2′) and containing two brake beams (10′, 12′) each assigned to a wheel axle (22′) with two wheels (6′) respectively and extending parallel to this wheel axle (22′), which brake beams (10′, 12′) are connected with one another by way of pressing rods (8′) and carry brake blocks (14) which can be moved into a braking engagement with assigned braking areas of the wheels (6′) by actuating the cylinder piston drives (20a′, 20b′).
Braking system according to claim 26,
- characterized in that the toothed gearing (116′) and at least a portion of the nut screw drive (102′) are accommodated in an intermediate housing (66′) arranged between the housing halves (52′), which intermediate housing (66′) forms a section of the brake beam (10′).
