In addition, the movable support member 30 is fitted to the inside of the guide portion 24, the slider provided with a contact bearing 34 on one side toward the inner side of the guide portion 24 to be slidable in a set range (32) is provided, and the connecting member 35 of a predetermined length is formed in the outer direction to provide a structure that can be combined with the top of the stabilizer bar link coupled to the stabilizer bar installed in the subframe.

In addition, the variable adjustment means 40 is fixed to one side of the fixing member 20 is a predetermined length variable according to the power supplied from the ECU 15 is coupled to the guide portion 24 of the fixing member 20 The slider 32 is configured to move back and forth in the direction in which the guide portion 24 is installed.

FIG. 5 is a cross-sectional view of the movable support member 30 and the variable adjusting means 40 installed inside the guide part 24 of the fixing member 20 so as to easily identify the installation state.

That is, the variable adjusting means 40 installed on one side of the fixing member 20 is one end of the variable adjusting means 40 in accordance with the electrical signal transmitted from the ECU (15) provided separately to the moving support member 30 side or stretched to move the support member ( 30 is configured to linearly move back and forth inside the guide portion 24 of the fixing member 20. In the embodiment of the present invention, the solenoid valve is used as the variable adjusting means 40. By using the movable support member 30 can be configured to be movable back and forth.

As shown in the longitudinal cross-sectional view of FIG. 6, a c-shaped guide part 24 having a predetermined space part is formed at one side of the fixing member 20, and a stabilizer bar is formed inside the guide part 24. The movable support member 30 to which the link 4 is connected is installed, and the guide groove 25 is formed in the same direction as the guide part 24 installation direction on the upper and lower surfaces thereof so as to move smoothly according to the operation of the variable adjusting means. The upper and lower guide protrusions 36 are formed on the upper and lower surfaces of the slider 32 which are fitted into the inner guide groove 25 of the guide part 24 and are slidably moved. The inner surface and the outer surface of the guide portion 24 is in contact with the rolling bearing movable 34 is configured to be configured.

The variable adjusting device 100 of the position stabilizer bar link according to an embodiment of the present invention is a variable position on the basis of a signal transmitted from the ECU 15 separately installed information about the running speed, steering angle speed, turning radius, etc. of the vehicle and The distance is determined and configured to operate.

That is, in the case where the vehicle is traveling straight at high speed, the solenoid applied to the variable adjusting means 40 coupled to one side of the fixing member 20 installed in the strut assembly 10 according to the vehicle speed information transmitted from the ECU 15. The valve 42 pulls the plunger 44 to the valve body side as far as possible to position the slider 32 connected to the plunger 4 as far forward as possible (see FIG. 7).

As the slider 32 moves, the upper end of the stabilizer bar link coupled to the coupling member 35 also moves forward along the movement of the coupling member 35 protruding outwardly from one side of the slider 32. As the pivoted stabilizer bar link moves forward, the lower end of the stabilizer bar link coupled to the stabilizer bar pulls backwards, reducing the toe-in angle of the wheels and improving the straightness of the vehicle, as well as on graded roads. To prevent the vehicle and steering wheel from tipping.

In addition, the solenoid valve 42 which is a variable adjusting means 40 coupled to one side of the fixing member 20 according to the vehicle speed, steering angle speed, and turning radius transmitted from the ECU 15 when turning or parking at a low speed. Pushes the plunger 44 away from the valve body as far as possible, and the slider 32 connected to the plunger 44 is positioned as far back along the guide portion 24 (see FIG. 8).

Therefore, as the slider 32 moves, the connecting member 35 is also moved rearward, and the rear movement of the connecting member 35 is also moved together with the upper end of the stabilizer bar link coupled to the connecting member 35. As the upper end of the stabilizer bar link moves to the rear side, the stabilizer bar link coupled to the stabilizer bar is flipped to the rear, and the lower end of the stabilizer bar link is pushed to the front side to induce a tow-out of the wheel to secure recovery performance at low speed. Of course, it is possible to secure driving stability due to the understeer tendency during bumping.

FIG. 9 is a graph showing toe-in and toe-out states which are actually changed by moving back and forth of the stabilizer bar link according to the exemplary embodiment of the present invention.

That is, the graph curve before the change shown in the graph is a test value in a vehicle without a fixed or stabilizer bar link, and the graph curve after the change is a test value for a vehicle to which the variable structure of the stabilizer bar link according to the embodiment of the present invention is applied.

As can be seen from the graph, the vehicle to which the variable structure of the stabilizer bar link according to the embodiment of the present invention is applied to affect the toe-in and toe-out angles under the same conditions as the conventional vehicle, thereby ensuring driving stability of the vehicle.
