RAIL VEHICLE BRAKE CONTROL DEVICE

摘要

A rail vehicle brake control device includes a brake control unit that is mounted on each truck and generates a pressure control signal for controlling a brake cylinder pressure that acts on a brake cylinder based on a service brake command and an emergency brake command, an electromagnetic valve unit that includes a brake control valve that adjusts a pressure of compressed air supplied to the brake cylinder according to the pressure control signal, and a relay valve that outputs the brake cylinder pressure corresponding to the compressed air supplied from the electromagnetic valve unit. The electromagnetic valve unit includes a release isolation magnet valve that adjusts a pressure of the compressed air supplied to a primary side of the relay valve, and the release isolation magnet valve is operated by receiving power source supply from a brake control device mounted on another truck.
