Stabilizer for vehicle

1. A stabilizer for a vehicle installed between a pair of wheels of the vehicle, the stabilizer comprising:

a first bar disposed to extend in a width direction of the vehicle;

an actuator supported by a vehicle body of the vehicle and coupled to the first bar and a first connecting member to move the first bar in the width direction of the vehicle; and

a second bar having one side connected to the first bar and the other side connected to one side of a wheel supporter which supports one wheel of the pair of wheels of the vehicle,

wherein, when the first bar is moved in the width direction of the vehicle, the other side of the second bar is moved so that the one side of the wheel supporter is moved in an upper direction or a lower direction of the vehicle.

2. The stabilizer of claim 1 , wherein:

the actuator includes a hollow motor; and

the first bar is coupled to the hollow motor to be movable through the hollow motor.

3. The stabilizer of claim 2 , wherein a central axis of the hollow motor is disposed to be collinear with a rotating shaft of the wheel.

4. The stabilizer of claim 2 , wherein:

a pair of second bars, each of which is identical to the second bar, are formed to be disposed at both ends of the first bar;

the pair of second bars are connected to the wheel supporters of the pair of wheels of the vehicle; and

when one of the pair of second bars is moved in the upper direction, the other thereof is moved in the lower direction.

5. The stabilizer of claim 4 , wherein support members configured to support the first bar are provided at both sides of the actuator of the vehicle body.

6. The stabilizer of claim 1 , wherein guiders configured to guide movement in a vertical direction of the other side of the second bar are formed at the vehicle body of the vehicle.

7. The stabilizer of claim 1 , wherein a third bar is connected to the other side of the second bar by a second connecting member, and the third bar is coupled to one side of the wheel supporter.

8. The stabilizer of claim 1 , wherein the first connecting member includes a ball joint or universal joint.

9. The stabilizer of claim 1 , wherein the wheel supporter includes at least one of an upper arm for supporting the wheel, a lower arm disposed under the upper arm, and a knuckle arm coupled between the upper arm and the lower arm.

10. The stabilizer of claim 1 , wherein the second bar extends in a vertical direction and is disposed to be oblique in an outside direction of the vehicle from a lower side toward an upper side thereof.

11. The stabilizer of claim 1 , wherein:

a pair of first bars, each of which is identical to the first bar, a pair of actuators, each of which is identical to the actuator, and a pair of second bars, each of which is identical to the second bar, are formed; and

the pair of first bars, the pair of actuators, and the pair of second bars are disposed to be laterally symmetrical in the width direction of the vehicle.

12. The stabilizer of claim 11 , wherein the pair of first bars, which are connected to the pair of actuators, are operated so that one of the pair of second bars is moved in the upper direction and the other thereof is moved in the lower direction.

13. The stabilizer of claim 1 , wherein the pair of wheels of the vehicle refers to one or both of front wheels and rear wheels of the vehicle.

14. The stabilizer of claim 1 , wherein a housing of the actuator is formed of aluminum.
