摘要： A knuckle for a rail car coupler that reduces bending of an intermediate portion of the pivot pin that coupled the knuckle to a rail car coupler. The knuckle has a body with a throughbore defining a first bearing surface at a first end of the throughbore and a second bearing surface and a second end of the throughbore. A support extends from the body into the throughbore and includes a third bearing surface positioned between the first bearing surface and the second bearing surface. When a pivot pin is positioned in the throughbore, it will contact the first bearing surface, the second bearing surface, and the third bearing surface, with the third bearing support protecting against bending of the pivot between the first and second bearing surfaces.

摘要： A bypass for an air dryer having an inlet, a prefiltration stage having a drain valve to purge contaminants, a pair of inlet valves in communication with the prefiltration stage to control the flow of compressed air through the desiccant towers, and an outlet coupled to the pair of desiccant towers. The bypass may be a bypass valve that is normally open to the outlet when the air dryer is unpowered and pilotable to be a closed to allow air to flow to the prefiltration stage when the air dryer is powered. The bypass may be a three-way valve that is normally coupled to the outlet and that may be piloted to connect to the prefiltration stage when the dryer is powered. The bypass may also be a check valve that opens in response to pressure in the inlet to allow compressed air to flow directly to the outlet.

摘要： A combined dirt collector and cutout cock (CDC & COC) device for a rail car control to prevent unintentional re-pressurization of the control valve and rail car braking system. The device has an inlet (12) configured for interconnection to an air supply, an outlet (14) configured for interconnection to a control valve of a rail car, a valve (16) moveable between a first position where an inlet is connected to an outlet and a second position where the inlet is isolated from the outlet, and a control valve vent (18) positioned downstream of the valve and configured to open in response to the valve being moved into the second position. The valve may include a ball (22) having a first passageway (24) for selectively connecting and disconnecting the inlet from the outlet and a second passageway (20) formed therethrough that is positioned to interconnect the outlet with the vent when the valve is in the second position.

摘要： A locking mechanism for a brake cylinder that has a tube surrounding the hollow shaft of the brake cylinder with a first set of teeth formed along an outer surface thereof. A gate having a second set of teeth corresponding to the first set of teeth is moveable in between a first position, wherein the first and second set of teeth are engaged to prevent movement of the brake cylinder piston, and a second position where the first and second set of teeth are disengaged to allow movement of the brake cylinder piston. A spring biases the gate into the locked position and a supplemental piston responsive to a source of brake pipe pressure can move the gate into the unlocked position so that the main piston is free to move

摘要： A brake cylinder with a cylinder body having a first flange extending radially therefrom to form a radial edge with a bevel and a non-pressure head having a second flange extending radially therefrom, wherein the second flange is spaced apart from the first flange to define a first gap and includes an angled portion that extends over the bevel of the first flange to define a second gap in communication with the first gap. The two flanges form a gap in communication with the interior of the brake cylinder that extends outwardly to a V- shaped gap between the bevel of the first flange and the angled portion of the second flange to define a brake cylinder vent. The vent may be limited to four predetermined locations spaced equidistantly about the brake cylinder or the vent may extend circumferentially about the brake cylinder.

摘要： A system for automatically updating route information to a locomotive that includes a route computer and voice radio encoder that merges data representing temporary changes in a route with a voice radio call placed by a dispatcher to a locomotive engineer. A voice radio decoder coupled to the locomotive cab voice radio extracts the data representing the temporary changes from the voice radio signal and provides the data directed to the energy management system so that there is no need for the engineer to manually enter the temporary data.

摘要： A system that determines state of a locomotive and transmits the occurrence of any predetermined events to an off-board system. The onboard subsystem includes an event detection module programmed to receive data defining the state of a locomotive to determine whether the received state of the locomotive comprises an event as well as a transmission module programmed to transmit to an off-board subsystem data defining a status. An onboard database have reference variable values is used to compare the existing state of the locomotive to predetermined events. If an event is determined to have occurred, the occurrence of the event is transmitted to the off-board system.

摘要： A system and method for automatically calibrating the flow measurement device (44) of a locomotive air brake control system. The air brake control computer (16) activates a magnet valve (54) to create a predetermined flow from the brake pipe through an orifice (60) to exhaust, thereby creating a reference flow value to enable the calibration of the flow measurement device. The system reduces the likelihood of human error and variability by automating the steps necessary for flow measurement calibration under computer control.

摘要： A powered hand brake for locomotive brakes that latches a brake chain into a locked position after the brake cylinder has applied the locomotive brakes. A computer controlled brake system may be interconnected to the brake cylinder and the latch and programmed to set the latch into the latched position when the brake cylinder has moved the locomotive brake into the applied position. An actuator is coupled to the brake chain to take up slack in the brake chain as the brake chain moves between the first and second positions. The actuator can comprise a motor or a tensioning cylinder that takes up slack in the brake chain after the brakes have been applied. Alternatively, the actuator may comprise a linkage connecting the brake chain to the locomotive brake so that the slack in the brake chain is taken up as the brakes are applied.

The check valve and quick service valve are coupled to provide a single system having multiple valve seats for selective communication between quick service pressure and brake cylinder pressure on one hand, and between a brake cylinder maintaining pressure and brake cylinder pressure on the other hand.
