BRAKING SYSTEM CONTROL AND ANTI-LOCK DEVICES

摘要

This anti-lock device for the wheels of motor vehicles comprises a detector adapted to transmit a signal proportional to the slip of a wheel, a member for modulating said signal which is interposed between a source of vacuum and an expansion unit of the braking circuit. Said detector is adapted to compare two signals of which the magnitudes are proportional to the momentary speed of the wheel and to the real speed of the vehicle in relation to the ground, respectively, so as to energize said modulating member.
