    Electronically controlled power steering system
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronically controlled power steering system using steering force directly as an assist device for a vehicle and using driving power of an electric motor. In particular, a cylinder tube is mounted by installing a piston sensor without forming a flow path in a piston shaft connected to a steering gear. The present invention relates to an electronically controlled power steering system in which an electronic control unit controls a hydraulic pump and controls a steering force to improve steering power of a power steering.
    In general, the electronically controlled power steering, which is one of the steering devices of the vehicle, is connected to a steering wheel 21 and a steering column 22, the steering column 22 is installed, and a steering gear on the input shaft 24, as shown in FIG. 1. 25 is connected and comprised.
    The electronic control power steering as described above, by installing the electric motor to the assist of the provisional force to transfer the driving force of the electric motor through the pinion engaged with the rack to supply the hydraulic pressure to the cylinder through the valve and the flow path structure to make the power assist operation is made. Steering force can be controlled.
    Therefore, the conventional electronically controlled power steering system as described above is complicated and difficult to manufacture by controlling hydraulic power by supplying hydraulic pressure by forming a flow path of a valve by a mechanical operation of an electric motor, a rack, and a pinion, thereby deteriorating steering function and performance. There was a problem to make, according to this there is a lot of inconvenience in the steering operation of the vehicle, there was a problem that the manufacturability is less.
    The present invention is equipped with a piston sensor without forming a flow path in the piston shaft connected to the steering gear to complement the above conventional problems, and electrically connecting the electronic control unit to the piston sensor, the solenoid valve to the electronic control unit The hydraulic control unit electrically controls the hydraulic pump, and the electronic control unit controls the hydraulic pump and supplies the hydraulic pressure through the solenoid valve to control the driving force to improve the power steering.
    1 is a perspective view of a general electronic control power steering.

    * Explanation of symbols for main parts of the drawings
    1: steering gear, 2: piston shaft, 3: piston sensor, 4: electronic control unit, 5: solenoid valve, 6: hydraulic pump
    In the configuration of the present invention, as shown in FIG. 2, the piston sensor 3 is mounted without forming a flow path in the pinion housing 2 connected to the electronically controlled power steering gear 1. The electronic control unit 4 is electrically connected to the electronic control unit 4, and the four solenoid valves 5 and the hydraulic pump 6 for forward and reverse direction control are electrically connected to the electronic control unit 4.
    Reference numeral 7 is a cylinder tube.
    According to the present invention configured as described above, when the operation of the electronic control power steering is made, as shown in FIG. 3, the electronic control unit 4 controls the hydraulic pump 6 to supply hydraulic pressure to the cylinder tube 7. The solenoid valve 5 is electrically controlled to open and close at the same time so that the solenoid valve 5 can electrically control the hydraulic pressure generated from the hydraulic pump 6 to control the steering force.
    Therefore, in the present invention as described above, the electronic control unit is electrically connected to the piston sensor, the solenoid valve and the hydraulic pump are electrically connected to the electronic control unit, and the electronic control unit controls the hydraulic pump to send hydraulic pressure to the cylinder tube. It is possible to improve the steering power of the power steering by controlling the steering power by supplying the control through the solenoid valve.
    As described above, according to the present invention, a piston sensor is mounted on the piston shaft connected to the steering gear, and the piston sensor is electrically connected to the piston sensor. The solenoid valve and the hydraulic pump are connected to the electronic control unit. The electronic control unit controls the hydraulic pump through the solenoid valve to control the hydraulic power by electrically connecting the hydraulic pressure to the cylinder tube. The steering power of the power steering can be improved to improve the power steering function and performance of the vehicle. It is possible to improve the manufacturability by removing the flow path device, and it is easy to adjust the steering force to improve the operating force of the steering has the effect of giving convenience in use.
