Modular locomotive brake control unit

摘要

A modular locomotive brake control unit having a manifold (104) with electropneumatic modules each including electropneumatic and pneumatic elements removably mounted thereon each as a unit from the manifold. An electropneumatic equalization reservoir module (ERCP) controls the pressure at the equalization port. A brake pipe module (BPCP) controls brake pipe port pressure in response to the equalization reservoir port. An electropneumatic independent brake module (20CP) controls pressure at the independent brake port as a locomotive brake signal. An electropneumatic brake signal module (EBV) provides a pneumatic train brake signal. A controller controls the electropneumatic modules. Each electropneumatic unit includes an electropneumatic supply valve and an electropneumatic exhaust valve and preferably an electropneumatic valve having a first input connected to the supply and exhaust valves. The electropneumatic modules includes a common block having a first interface with the manifold and including the electropneumatic valve as to supply and exhaust valves and includes an auxiliary block mounted to the common block having module specific pneumatic and electrical elements mounted on the auxiliary block.
