ANTI-LOCKING BRAKE FORCE REGULATING DEVICE

摘要

ANTI LOCKING BRAKE FORCE REGULATING DEVICE An anti-locking brake force regulating device for rail vehicles has a digital evaluation circuit which monitors the speed, acceleration and slip of at least one braked wheel and transmits braking instructions to a brake actuating element. The instructions include a rapid or slow increase or decrease of brake pressure or maintaining the brake pressure constant. In order to achieve a smooth control during a braking operation, the evaluation circuit is such that after instructing a rapid change of brake pressure in response to exceeding a predetermined threshold value a slow change of brake pressure in the same direction as the rapid change is instructed if the threshold value is again exceeded and the slow pressure change begins by a maintaining brake pressure constant phase. The slow or pulsed brake pressure change is preferably maintained for a fixed predetermined period of time.
