    Steering force variable of the steering wheel
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering wheel, and more particularly, a steering variable device of a steering wheel which enables the steering force of the steering wheel to be converted according to the vehicle speed to achieve adjustment safety and driving safety for the driver. It is about.
    In general, a steering system of a vehicle is a device for steering in order to arbitrarily change the direction of movement of a vehicle. The steering system is a part in which a driver directly steers and transmits the manipulation force to a steering gear and a link, and a steering wheel. , Steering shaft, and column.
    The steering shaft is a shaft for transmitting the operating force of the handle to the steering gear, the handle is coupled to the upper end, the steering gear is coupled to the lower end.
    The conventional steering wheel as described above has a stable driving performance at low speed because the steering force is dependent on a constant pump pressure, but the steering wheel is lighter at high speed to provide unstable driving performance when the driver turns the corner. Is generated.
    Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to make the steering wheel feel light handling at low speed, the handling operation is made heavy at high speed, the driver's adjustment stability and running Its purpose is to enable safety.
    1 is a schematic view showing a steering wheel axis according to the present invention
    FIG. 2 is a cross-sectional view taken along line “B-B” of FIG. 1.
    3 is a detailed view of "C" of FIG.
    4 is an operational state configuration diagram according to the present invention
    <Description of the symbols for the main parts of the drawings>
    DESCRIPTION OF SYMBOLS 11 Steering shaft 12 Column 13 and 14 Pad 15 Solenoid 16: Controller 17 Vehicle speed sensor 18 Slip groove 19 Compression spring 20 Plunger
    The present invention for achieving the above object, the steering shaft is formed with a slip groove along the circumference; A pair of left and right pads on which opposite ends have a holding force of a compression spring and an inner side thereof is in close contact with the slip groove; Plungers provided on both sides of the pad; A solenoid provided on the column to selectively push and pull the plunger; A controller for operating the solenoid; Characterized in that the vehicle speed sensor for transmitting a signal value according to the vehicle speed to the controller.
    Hereinafter, with reference to the accompanying drawings a preferred embodiment of the steering force variable device of the steering wheel according to the present invention will be described in detail.
    Figure 1 shows a schematic view of the steering wheel shaft according to the invention, Figure 2 shows a "B-B" line cross section of Figure 1, Figure 3 shows a "C" part of Figure 1 detail. And, Figure 4 shows an operational state configuration diagram according to the present invention.
    As shown, the present invention includes a steering shaft 11, a column 12 covering the steering shaft 11, and a pair of pads 13 and 14 for controlling the rotational force of the steering shaft 11. ), A solenoid 15 for moving the pads 13 and 14, a controller 16 for controlling an operating force of the solenoid 15, and a vehicle speed signal value inputted to the controller 16. It is configured to include a vehicle speed sensor 17.
    Slip grooves 18 are formed on one side outer circumferential surface of the steering shaft 11 along a circumference, and the slip grooves 18 are provided with pads 13 and 14 to be in close contact with each other, and the pads 13 ( 14 is in close contact with the left and right pairs and the opposite ends are in contact with each other is provided with a compression spring 19, the slide is provided on the inner peripheral surface of the column (12).
    In addition, a plunger 20 protrudes from the outer exposed surface of the pads 13 and 14, respectively, and the plunger 20 controls the pads 13 and 14 by the operating force of the solenoid 15. 11) is provided to slide in close contact with the slip groove (18).
    In addition, the controller 16 operates the solenoid 15 according to the input signal value, and the vehicle speed sensor 17 detects the vehicle traveling speed and outputs the detected signal value to the controller 16. Made of structure.
    Referring to the operating state according to the configuration as follows.
    As the vehicle speed of the vehicle increases as shown in FIG. 4, the vehicle speed sensor 17 transmits the signal value to the controller 16, and the controller 16 operates the solenoid 15. . At this time, the solenoid 15 pushes the plunger 20 shown in FIG. 3 according to the input signal value, and the plunger 20 is a pair of pads 13 and 14 as shown in FIG. 2. Are simultaneously pushed on both sides, and in a continuous operation, the pads 13 and 14 compress the compression spring 19 while the inner circumferential surface is in close contact with the slip groove 18 of the steering shaft 11 so that the steering shaft 11 ) To control the rotational force.
    Therefore, the driver can rotate the steering wheel lightly when the vehicle is low speed, and the steering wheel must be rotated with a strong force during the high speed driving of the vehicle.
    Therefore, the steering wheel steering force sensing device according to the present invention, the handle is made to feel the handling operation lightly at low speed, and the handling operation is made heavy at high speed to achieve the adjustment stability and driving safety effect will be.
