PURPOSE:To make a brake mechanism possible to function as a pumping brake too, by letting those of brake pedal, controller, gear pulser, solenoid brake, actuator and sensor module work so organically. CONSTITUTION:Whether or not there is a wheel lock is detected by a gear pulser 5 and a sensor 4, and in time of being locked, a signal is inputted into a first operational amplifier 7b of a sensor module 7. The first operational amplifier 7b compares this signal with that out of a power regulator 9, leading out an output signal, thus a second operational amplifier 7c operates. An OR logical circuit 7d conducts this output signal to a transistor 8b of an actuator 8, making a relay 8a and a solenoid valve 3 both operate, and the output signal is combinedly conducted into a controller 2 together with a signal out of the relay 8a, outputting an intermittent operation signal to a brake pedal 1 and making it perform pumping brake action, thus a slip and rolling are prevented from occurring. |
