7. air compressor based on claim 1-6 any one and the intelligence control system of hydraulic steering pump integrated mechanism,
It is characterized in that, including:
For measuring the baroceptor of car load air pressure, for measuring steering wheel angle sensor and the control of wheel steering
Device, air compressor (1), electromagnetic clutch (2), motor (5) and hydraulic steering pump (6) are equipped with controlling organization, air pressure transmission
Sensor, steering wheel angle sensor, air compressor (1), electromagnetic clutch (2), motor (5) and the control of hydraulic steering pump (6)
Mechanism processed is connected with controller respectively.
Air compressor the most according to claim 7 and the intelligent control method of hydraulic steering pump integrated mechanism, its feature
It is, including following rate-determining steps:
Step one, controller is believed according to the pressure signal of the baroceptor received and the rotation of steering wheel angle sensor
Number, it is judged that in car, car load air pressure is the most enough and whether steering wheel rotates；
Step 2, if car load air pressure is less than minimum air pressure, steering wheel is without rotating, then controller control electromagnetic clutch (2) closes up,
And starting motor (5), motor (5) drives air compressor (1) with rated load operation until car load air pressure reaches air pressure and sets
Value, now hydraulic steering pump (6) running light, after reaching air pressure setting value, controller controls electromagnetic clutch (2) and separates,
Air compressor (1) is shut down, motor (5) idle running；
If car load air pressure is more than minimum air pressure, steering wheel rotates, then controller controls electromagnetic clutch (2) separation, controller root
According to Vehicle Speed, control motor (5) and run with setting speed；
If car load air pressure is less than minimum air pressure, steering wheel rotates, then controller control electromagnetic clutch (2) closes up, and starts electricity
Machine (5), motor (5) drives air compressor (1) and hydraulic steering pump (6) with rated load operation with rated power；
If car load air pressure is more than minimum air pressure, steering wheel is without rotating, then controller controls electromagnetic clutch (2) separation, motor (5)
Idle running.
