摘要： The electronic brake control simulates by electronic means various real changes over time of the pneumatic pressures in a braking system, in particular the pressure in the main air pipe of the train, the pressure in the R containers of the individual wagons and the pressure in the individual brake cylinders. When the brakes are released, the values are determined from these model values and the actually backfed air volume, from which values the pilot control pressure for a relay valve can be increased in order to release the brakes more rapidly. The train model determines, by an adaptive learning method at the end of a brake releasing process, values for the volume of the main air pipe and the R containers of the train, so that the train model adapts itself to the actually existing train.

摘要： A hydrodynamic retarder is revealed having a rotor blade wheel and a stator blade wheel each with two different types of blading, i.e. an inner blading enclosed by an outer blading. The two blade rings are provided with blades inclined in opposite directions. This allows said retarder to be operated in both directions of rotation. A particularly advantageous development of the invention is that the retarder is operated as a counter-rotating retarder, whereby the stator is rotated in the opposite direction by means of a reversing gear. Thus, a vehicle can be hydrodynamically braked almost to standstill. When integrating the retarder into a rail vehicle, the rotor can be driven by the wheel sets separately from the stator. An identical braking effect is obtained in both directions of travel. Moreover, the inner working circuit enclosed by the outer working circuit can be arranged radially in such a manner that the radially outer front cross-sectional area for the fluid flow is of identical size as the radially inner front cross-sectional area. This prevents shock losses and increases the braking power of the retarder.

摘要： A drive for high-speed locomotives has a variable-speed electric motor which transmits torque to the input shaft of a hydrodynamic power transmission having a hydrodynamic torque converter and a hydrodynamic coupling for transmission of torque to the output shaft which drives the wheels through the medium of a mechanical transmission and cardan shafts. The control unit of the drive engages the converter in the lowest speed range, the coupling in the highest speed range, and the coupling or the converter in the intermediate speed range. In the intermediate speed range, the coupling is engaged when the control unit ascertains that the ratio of maximum traction effort of the drive in engaged condition of the coupling at the momentary intermediate speed to the resistance which the locomotive encounters exceeds one. The resistance is ascertained automatically by determining the tractive effort of the drive in engaged condition of the converter at the momentary intermediate speed and by subtracting therefrom the accelerating force which is the product of the mass of locomotive plus cars (if any) and the momentary acceleration of the vehicle. The output shaft receives braking torque from a hydrodynamic brake whose controls include safety features to insure the application of brake in the event of failure of the primary actuating device.

摘要： A deadhead return control system for a locomotive or a control car similar to a locomotive having a deadhead stop and a piston valve with the connection status of the piston valve being controlled by the status of the deadhead stop. A first end of the deadhead stop is connected to a pilot end of the piston valve, a second end of the deadhead stop is connected to the atmosphere, a third end of the deadhead stop is connected to the external main air pipe. When the deadhead stop has a closed status, the first end of the stop is connected to the second end of the stop and when the stop has an open status, the first end of the stop is connected to the third end of the stop to allow for the air from said main air pipe to flow into the piston valve.

摘要： A railway car air brake hose support bracket has an upper portion with first and second attachment members, a lower portion and an air hose connector. The first attachment member enters into and engages a portion of an accessible compartment of an uncoupling mechanism housing below the coupler head, and the second attachment member is secured to an air brake hose support lug of the railway car coupler. The air brake hose connector engages an air brake hose assembly and suspends this hose assembly from the railway coupler at a predetermined distance above the rail bed. A method of installing the hose support bracket includes positioning the first and second attachment members, securing them in place, and attaching one or more railway brake hose units to the air hose connector, either before or after this positioning and securing of the upper portion of the bracket.
