Title:
BRAKE INSTRUCTION CONVERTING DEVICE
Document Type and Number:
Japanese Patent JPS5950850
Kind Code:
A
Abstract:

PURPOSE: To make it possible to couple electric cars having braking systems of different control types, together, by optionally and mutually controlling solenoid- operated type air-brakes and electrical instruction type air-brakes.

CONSTITUTION: There are provided a relay MBR which is energized by a brake controller 20 for controlling an electrical instruction type air brake, and an air-electricity converter for converting pressure in an SAP pipe 5 in a solenoid- operated type air-brake into an analog electrical signal. Further, there are provided first converting devices 41 through 44 receiving the analog signal through a normally closed contact in the relay, for converting the analog signal into an electrical brake instruction signal on a brake instruction extracting cable 4 in a second electric car, and second converting devices receiving electrical brake instruction signals on brake instruction extracting cables SB1 through SB4 through normally opened contacts in the relay in the second electric car, for converting the electrical brake instruction signals into analog electrical signals. With this arrangement, electric cars having electrical instruction type air brakes may be communicatedly controlled.
