Abstract

There is provided a stabilizer for a vehicle, including a torsion bar fixed to a car body and configured to be rotated about a longitudinal axis of rotation without changing a position, two arm links connected to both ends of the torsion bar, and two drive links connected to each of the two arm links through a ball joint so as to be able to be rotated three-dimensionally, in which the two drive links are configured to, during cornering of the vehicle, adjust a degree of torsion of the torsion bar by rotating about an axis of rotation of a strut assembly or a steering knuckle connected to the two drive links.

Claims (40)

1 . A stabilizer for a vehicle, comprising:

a ball joint that enables three-dimensional rotation;

an arm link hinge that enables rotation with respect to an axis of the arm link hinge without bending;

a torsion link hinge that enables rotation with respect to an axis of the torsion link hinge without bending, wherein one end of the torsion link hinge is fixed to a vehicle body;

a drive link, wherein one end of the drive link is fixed to one of a strut assembly or a steering knuckle of one side of the vehicle, and the other end of the drive link is connected to one end of the ball joint;

a torsion link, wherein one end of the torsion link is connected to one end of the arm link hinge, and the other end of the torsion link is connected to the other end of the torsion link hinge; and

an arm link, wherein one end of the arm link is connected to the other end of the ball joint, and the other end of the arm link is connected to the other end of the arm link hinge;

wherein the torsion link hinge is configured to allow an angle between the torsion link and the vehicle body to be changed, and the arm link hinge is configured to allow an angle between the arm link and the torsion link to be changed, and the drive link and the torsion link are positioned at different heights so that the arm link is inclined with respect to a plane of rotation of the drive link,

wherein the ball joint, the arm link, the arm link hinge, and the torsion link are configured to move forward or backward of the vehicle according to the rotation of the drive link, thereby changing a distance between the ball joint and the torsion link hinge, causing the torsion link to twist and generating a torque, and

wherein the torque applies a vertical force to the drive link, a magnitude of the vertical force varying as a function of the distance between the ball joint and the torsion link hinge.

2 . The stabilizer according to claim 1 , further comprising:

a torsion bar configured to twist with respect to a longitudinal axis of the torsion bar,

wherein one end of the torsion bar is fixed to the vehicle body, and the other end of the torsion bar is connected to one end of the torsion link hinge;

wherein the torsion link hinge is configured to allow an angle between the torsion link and the torsion bar to be changed, and the torsion link and the torsion bar are configured to twist and thereby generate the torque.

3 . The stabilizer according to claim 2 , further comprising:

a supplemental ball joint that enables three-dimensional rotation;

a supplemental arm link hinge that enables rotation with respect to an axis of the supplemental arm link hinge without bending;

a supplemental torsion link hinge that enables rotation about an axis of the supplemental torsion link hinge without bending, wherein one end of the supplemental torsion link hinge is connected to one end of the torsion bar;

a supplemental drive link, wherein one end of the supplemental drive link is fixed to one of a supplemental strut assembly or a supplemental steering knuckle of the other side of the vehicle, and the other end of the supplemental drive link is connected to one end of the supplemental ball joint;

a supplemental torsion link, wherein one end of the supplemental torsion link is connected to one end of the supplemental arm link hinge, and the other end of the supplemental torsion link is connected to the other end of the supplemental torsion link hinge; and

wherein the supplemental torsion link hinge is configured to allow an angle between the supplemental torsion link and the torsion bar to be changed, and the supplemental arm link hinge is configured to allow an angle between the supplemental arm link and the supplemental torsion link to be changed, and the supplemental drive link and the supplemental torsion link are positioned at different heights so that the supplemental arm link is inclined with respect to a plane of rotation of the supplemental drive link,

wherein the supplemental ball joint, the supplemental arm link, the supplemental arm link hinge, and the supplemental torsion link are configured to move forward or backward of the vehicle according to the rotation of the supplemental drive link, thereby changing a distance between the supplemental ball joint and the supplemental torsion link hinge, causing the supplemental torsion link and the torsion bar to twist and generating the torque, and

wherein the torque applies a vertical force to the supplemental drive link, a magnitude of the force varying as a function of the distance between the supplemental ball joint and the supplemental torsion link hinge.

4 . A stabilizer for a vehicle, comprising:

a ball joint that enables three-dimensional rotation;

an arm link sliding hinge that enables rotation with respect to an axis of the arm link sliding hinge without bending, wherein one end of the arm link sliding hinge is configured to provide a movable connecting point;

a torsion bar, wherein one end of the torsion bar is fixed to a vehicle body, and the other end of the torsion bar is connected to the other end of the arm link sliding hinge; and

an arm link, wherein one end of the arm link is connected to the other end of the ball joint, and the other end of the arm link is connected to one end of the arm link sliding hinge;

wherein the movable connecting point of the other end of the arm link is configured to be movable through the arm link sliding hinge,

wherein the arm link sliding hinge is configured to allow an angle between the arm link and the torsion bar to be changed, and the drive link and the torsion bar are positioned at different heights so that the arm link is inclined with respect to a plane of rotation of the drive link, and

wherein the ball joint and the arm link are configured to move forward or backward of the vehicle according to the rotation of the drive link, thereby changing a distance between the ball joint and the arm link sliding hinge, causing the torsion bar to twist and generating a torque, wherein the torque applies a vertical force to the drive link, a magnitude of the vertical force varying as a function of the distance between the ball joint and the arm link sliding hinge.

5 . The stabilizer according to claim 4 , further comprising:

a supplemental ball joint that enables three-dimensional rotation;

a supplemental arm link sliding hinge that enables rotation about an axis of the supplemental arm link sliding hinge without bending, wherein one end of the supplemental arm link sliding hinge is configured to provide a movable connecting point;

a supplemental arm link, wherein one end of the supplemental arm link is connected to the other end of the supplemental ball joint, and the other end of the supplemental arm link is connected to one end of the supplemental arm link sliding hinge, wherein the movable connecting point of the other end of the supplemental arm link is configured to be movable through the supplemental arm link sliding hinge;

wherein one end of the torsion bar is connected to the other end of the supplemental arm link sliding hinge, and the supplemental arm link sliding hinge is configured to allow an angle between the supplemental arm link and the torsion bar to be changed, and the supplemental drive link and the torsion bar are positioned at different heights so that the supplemental arm link is inclined with respect to a plane of rotation of the supplemental drive link, and

wherein the supplemental ball joint and the supplemental arm link are configured to move forward or backward of the vehicle according to the rotation of the supplemental drive link, thereby changing a distance between the supplemental ball joint and the supplemental arm link sliding hinge, causing the torsion bar to twist and thereby generate the torque, wherein the torque applies a vertical force to the supplemental drive link, a magnitude of the vertical force varying as a function of the distance between the supplemental ball joint and the supplemental arm link sliding hinge.
