Abstract
An electro-pneumatic braking system including a pneumatic pressure supply pipe, a generator for generating a vehicle load signal, a weighting system designed to supply a weighted pressure which defines a maximum braking pressure, limited as a function of the load signal, and braking control units connected to the weighting system and having a relay valve connected between the pipe and at least one brake cylinder, to cause the application to this cylinder of a controllable braking pressure, equal to or less than the weighted pressure. The weighting system includes an electro-pneumatic drive assembly, interposed between the pipe and the drive inlet of the relay valve and is connected to the pipe through a pressure limiter, and an electronic weighting control unit which controls this drive assembly as a function of the load signal, so as to modulate in predetermined ways the pressure at the drive inlet of the relay valve.
