| 81 | Thermally Optimized Railway Vehicle Brake System | US14282357 | 2014-05-20 | US20140345491A1 | 2014-11-27 | Robert Norman Scharpf; Maria H. Koon; Glyn A. Finch, JR.; Paolo Poli |
| A railway vehicle brake system includes at least two relay valves in electrical communication with one another and in fluid communication with a brake pipe, at least two friction brake units in fluid communication with each relay valve, and at least one electric brake unit in electrical communication with each relay valve. Upon a failure of one of the electric brake units, the relay valve in communication with the failed electric brake unit sends a signal to at least one other relay valve to provide pressurized fluid to the at least two friction brake units in fluid communication with the at least one other relay valve. The at least two relay valves may include integrated electric relay valves. The at least two friction brake units may include disc brake units. Each relay valve may be positioned between and in fluid communication with the brake pipe and a main reservoir pipe. | ||||||

| A push rod holder for use with a brake cylinder of a railroad vehicle is disclosed. The push rod holder includes an annular outer metal member and an annular inner elastomeric member. The annular inner elastomeric member is molded to an interior surface of the annular outer metal member. The push rod holder defines at least one set screw throughhole and a pair of aligned holder pin throughholes. Each of the throughholes is oriented perpendicularly to a longitudinal axis of the push rod holder. The brake cylinder includes a hollow piston rod and a push rod assembly inserted therein. The push rod holder concentrically fits onto the hollow piston rod. The annular inner elastomeric member assures that the push rod holder fits snugly about the hollow piston rod. At least one set screw is used to attach the push rod holder to the hollow piston rod via the at least one set screw throughhole. A holder pin device is used to lock the push rod holder to the hollow piston rod and the push rod assembly contained therein. The annular inner elastomeric member dampens vibrations encountered at the junction of the push rod holder, hollow piston rod and push rod assembly. The push rod holder thus reduces the likelihood of damage occurring to these components and prolongs the operational life of the brake cylinder. | ||||||
| 83 | Railroad car with brake system which applies less braking when empty than when loaded | US127557 | 1987-12-03 | US4775197A | 1988-10-04 | Robert A. Biegel |
| A railroad freight car comprising a freight-carrying first elongated body supported at one end by a first truck and at the other end by a second truck; each truck having a plurality of wheels and carrying air pressure operated braking apparatus for braking the wheels; the air pressure operated braking apparatus on the first truck including a pressurized air line having an air pressure sensor/changeover valve which governs the braking pressure applied only to the wheels of the first truck; the first truck having a bolster, spring-supported at each end by wheel-containing side frames, whereby the bolster is lowered relative to the frame when the elongated body condition varies from empty to loaded; a base mounting the air pressure sensor/changeover valve to the bolster; and, the valve having an arm responsive to change in height of the bolster relative to the frame to decrease the air pressure to the brake apparatus from a high pressure, when the elongated body is loaded, to a lower pressure when the elongated body has an empty load condition to thereby apply a predetermined high braking force to the wheels when the elongated body is loaded and apply a decreased or lower braking force to the wheels when an empty condition exists. | ||||||
| 84 | Vertical railway car air brake system | US404205 | 1982-08-02 | US4479567A | 1984-10-30 | Arthur C. Pearson |
| For application to railway cars having limited available transverse space for the brake system, a system of vertically extending brake levers and longitudinally extending brake rods is used to apply the air brake force to wheels located at opposite ends of the car. | ||||||
| 85 | Force-transmitting device | US39743573 | 1973-09-14 | US3830061A | 1974-08-20 | SEVERINSSON L |
| A force-transmitting device moves a rod into a compressible medium in an expandable cylindrical casing moving axially within a tube to deliver a force upon movement into contact with a load so that when the casing encounters a load the medium expands the casing and frictionally clamps it within the tube.
