Abstract
An independent steering system includes a knuckle fastened to a wheel, an upper arm connected at both ends to an upper end of the knuckle and a steering frame, respectively, a lower arm connected at both ends to a lower end of the knuckle and the steering frame, respectively, and a tie rod connecting the knuckle and the steering frame to each other.
Claims20
An independent steering system for a wheel of a vehicle, the independent steering system comprising:
- a knuckle configured to be fastened to the wheel;
- an upper arm, wherein a first end of the upper arm is coupled to an upper end of the knuckle and a second end of the upper arm is coupled to a steering frame;
- a lower arm, wherein a first end of the lower arm is coupled to a lower end of the knuckle and a second end of the lower arm is coupled to the steering frame;
- and
- a tie rod, wherein a first end of the tie rod is coupled to the knuckle and a second end of the tie rod is coupled to the steering frame, wherein a height of the second end of the tied rod is configured to be adjustable,
- wherein the first end of the tie rod is pivotably connected to a connection member extending unilaterally from the knuckle, and the second end of the tie rod is configured to move along a path of a guide slot provided in the steering frame.
