Steering angle limiting device and steering apparatus including the same
The present disclosure provides a steering angle limiting device including a bracket 41 fixed to a column housing 30 surrounding a steering shaft 10 , a wire 42 having one end fixed to the bracket 41 , and a wire stopper 43 fixed to the other end of the wire 42 , wherein the wire stopper 43 is fixed to the other end of the wire 42 in a state where the wire 42 passes through a wire hole 10 a formed to pass through the steering shaft 10 in a direction inclined to an axial direction of the steering shaft 10 , and a steering apparatus including the same.
1. A steering angle limiting device comprising:
a bracket fixed to a column housing surrounding a steering shaft;
a wire having one end fixed to the bracket; and
a wire stopper fixed to the other end of the wire, wherein the wire passes through a wire hole formed in the steering shaft from one opening formed at an outer surface of the steering shaft to another opening formed at the outer surface of the steering shaft.
2. The steering angle limiting device of claim 1 , wherein the wire stopper is formed to have a length longer than a size of the wire hole.
3. The steering angle limiting device of claim 1 , wherein the wire is configured to, as the steering shaft is rotated in one rotational direction, wire around the steering shaft while being moved through the wire hole.
4. The steering angle limiting device of claim 3 , wherein, when the wire stopper is caught on the steering shaft and the wire is no longer moved, the rotation of the steering shaft in the one rotational direction stops.
5. The steering angle limiting device of claim 4 , wherein, as the steering shaft is rotated in an opposite rotational direction to the one rotational direction, the wire wound by the rotation in the one rotational direction unwinds.
6. The steering angle limiting device of claim 5 , wherein, as the steering shaft continues to rotate in the opposite rotational direction, the wire winds in an opposite direction around the steering shaft.
7. The steering angle limiting device of claim 6 , wherein, when the wire stopper is caught on the steering shaft and the wire is no longer moved, the rotation of the steering shaft in the opposite rotational direction stops.
8. The steering angle limiting device of claim 2 , wherein the bracket is fixed to a bracket fixing portion located outside of the column housing.
9. The steering angle limiting device of claim 8 , wherein a tab is formed in the bracket fixing portion, and a bracket hole is formed in the bracket, and
the bracket is screwed to the bracket fixing portion by a bolt passing through the bracket hole and the tab.
10. The steering angle limiting device of claim 9 , wherein one end of the wire is fixed by welding to one surface of the bracket.
11. A steering apparatus comprising:
a steering shaft;
a column housing surrounding the steering shaft;
a bracket fixed to the column housing;
a wire having one end fixed to the bracket; and
a wire stopper fixed to the other end of the wire, wherein the wire passes through a wire hole formed in the steering shaft from one opening formed at an outer surface of the steering shaft to another opening formed at the outer surface of the steering shaft.
12. The steering apparatus of claim 11 , wherein the wire stopper is formed to have a length longer than a size of the wire hole.
13. The steering apparatus of claim 11 , wherein, the wire is configured to, as the steering shaft is rotated in one rotational direction, wind around the steering shaft while being moved through the wire hole 10 a.
14. The steering apparatus of claim 13 , wherein, when the wire stopper is caught on the steering shaft and the wire is no longer moved, the rotation of the steering shaft in the one rotational direction stops.
15. The steering apparatus of claim 14 , wherein, as the steering shaft is rotated in an opposite rotational direction to the one rotational direction, the wire wound by the rotation in the one rotational direction unwinds.
16. The steering apparatus of claim 15 , wherein, as the steering shaft continues to rotate in the opposite rotational direction, the wire unwinds and then winds in an opposite direction around the steering shaft.
17. The steering apparatus of claim 16 , wherein, when the wire stopper is caught on the steering shaft and the wire is no longer moved, the rotation of the steering shaft in the opposite rotational direction stops.
18. The steering apparatus of claim 12 , wherein the bracket is fixed to a bracket fixing portion located outside of the column housing.
19. The steering apparatus of claim 18 , wherein a tab is formed in the bracket fixing portion, a bracket hole is formed in the bracket, and
the bracket is screwed to the bracket fixing portion by a bolt passing through the bracket hole and the tab.
20. The steering apparatus of claim 19 , wherein one end of the wire is fixed by welding to one surface of the bracket.
