Automatic brake system of anti-lock brake system (ABS) simulator

摘要

The present invention provides an automatic brake device for an ABS simulator that provides a digital counter to automatically detect the target speed of the wheel and automates the operation of the inverter, the clutch, and the brake. It is to provide.;To this end, the present invention, a pair of flywheel (8A, 8B) and the flywheel (8A, 8B) that is rotated by the rotational power from the motor (2) variable control by the inverter 14 is in contact with the flywheel ( A pair of wheels 7A, 7B rotated by the rotation of 8A, 8B and braked by the ABS modulators 6, 5, 4 under test, and the flywheels 8A, 8B and the wheels 7A, 7B. An automatic brake apparatus of an ABS simulator having a plurality of rotational speed detection means (9A, 9B, 11A, 11B) for detecting the rotational speed of a); It is for setting the target value rotational speed of the flywheel 8A, 8B and the wheels 7A, 7B, and reaching the target value when the rotational speed from the rotational speed detection means 9A, 9B, 11A, 11B reaches the target value. A plurality of digital counters 1A to 1D for outputting signals; A plurality of magnetic clutches (3A, 3B) for transmitting and blocking rotational power from the motor (2) to the flywheels (8A, 8B); When the target value reaching signal from the digital counters 1A to 1D is input, the motor end control signal is output to the inverter 14 and the operation end control signal is output to the magnetic clutches 3A and 3B, and the ABS modulator unit ( 6, 5, and 4 is further provided with a controller 10 for outputting a brake operation start signal.
