Inventors: Waldrop, Jeremy S.; Clarke, Bryan J.;
Assignee: Zeftron, Inc. (Montgomery, IL)
Primary Examiner: Graham; Matthew C.
Assistant Examiner: Siconolfi; Robert A.
Attorney, Agent or Firm: Zickert; Lloyd L.
A pneumatic railcar braking system for freight or passenger cars, wherein the system is operable as an electronically controlled pneumatic brake system in conjunction with a head end unit in the locomotive or as a conventional pneumatic brake system in conjunction with a pneumatic brake control in the locomotive. |
|
DETAILED DESCRIPTION The invention is hereby claimed as follows: 1.
A brake system for a train including a locomotive and a plurality of cars connected to the locomotive, intercommunicating brake pipes on the cars and locomotive, air supply means on the locomotive for supplying air to the brake pipes, each car further including an air supply reservoir, a manually operable retainer valve, a brake cylinder for producing a braking function, means for directing air from the air supply to the brake cylinder for brake application and venting that air for brake release, said air directing means on at least one of the cars further including a control valve and a car control device for operating the control valve, the control valve responding to either pneumatic signals from the brake pipe or electronic signals from the car control device, said car control valve including a pneumatically pilot operated relay valve for connecting the supply reservoir to the brake cylinder, a solenoid operated application valve responsive to a brake application signal from the car control device to produce a pilot pressure in a pilot line to said relay valve for actuating said relay valve to supply braking air to the brake cylinder, a solenoid operated release valve responding to brake release signals from the car control device venting the pilot pressure in said pilot line, a two-position pneumatically actuable brake cylinder release valve connected to said relay valve and the brake cylinder and having an exhaust connected to said retainer valve, means for latching said cylinder release valve in one position for normal service application functions, and means for driving said cylinder release valve to another position for connecting the brake cylinder to the retainer valve during exhausting of the brake cylinder, and a pneumatic emergency circuit for producing an emergency pilot pressure and providing emergency braking functions.
2.
The brake system of claim 1, which further includes an electronic cylinder release valve for shuttling said brake cylinder release valve during brake release functions to exhaust brake air to said retainer valve, and pressure transducers for providing electric signals to the car control device as to brake pipe pressure, brake cylinder pressure, supply reservoir pressure and pilot line pressure to the pneumatic relay valve
