摘要： 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.

摘要： An anti-lock device for the brakes of vehicles, particularly rail vehicles, regulates the applied braking force. An evaluation circuit monitors the speed, acceleration and slip of at least one braked wheel and in response to the rotational behavior of the wheel generates instructions for the brake actuating element. The evaluation circuit maintains the brake pressure constant during the initial phase upon the first application of brakes until the wheel acceleration falls below a predetermined negative threshold value. The initial phase is terminated when the wheel acceleration falls below a further predetermined reference value which is lower than the first threshold value. Upon termination of the initial phase, the brake pressure is again varied in a manner as known in the art.
