Braking control system for a railway or tramway vehicle with integrated anti-slip and anti-lock functions for the wheels

摘要

A system that performs anti-slip and anti-lock functions of the wheels in a vehicle provided with a pneumatic braking system. The system includes a brake control apparatus to which is connectable a plurality of electro-pneumatic valve units for control of the brake cylinders associated with the wheels/axles. These valve units are controlled in such a way as selectively to permit application of a braking pressure to the associated brake cylinders, holding this pressure, and discharge of the pressure from the brake cylinders.
