Radial telescope bushing for steering column
View Patent ↗A bushing assembly for a steering column having a fixed jacket and a telescope jacket is provided having a set screw configured for insertion into the fixed jacket, and a radial telescope bushing co-acting with the set screw and having a post and a curved bushing portion configured to pre-load the radial telescope bushing against the telescope jacket to provide a lash-free interface between the fixed jacket and the telescope jacket.
1. A steering column assembly comprising:
a. a steering column shaft;
b. a fixed jacket having a jacket aperture formed therein;
c. a telescope jacket configured for telescopic movement relative to the fixed jacket; and
d. a bushing assembly comprising:
i. a set screw disposed in the jacket aperture; and
ii. a radial telescope bushing co-acting with the set screw and having a post and a curved bushing portion configured to pre-load the radial telescope bushing against the telescope jacket to provide a lash-free interface between the fixed jacket and the telescope jacket.
2. The steering column assembly of claim 1 , wherein the set screw includes an aperture formed therein.
3. The steering column assembly of claim 2 , wherein at least a portion of the post is inserted into the aperture.
4. The steering column assembly of claim 1 , wherein the set screw includes a threaded outer surface.
5. The steering column assembly of claim 4 , wherein the jacket aperture is threaded to receive the set screw threaded outer surface.
6. The steering column assembly of claim 1 , wherein the curved bushing portion has a radius of curvature that is less than a radius of curvature of the telescope jacket.
7. The steering column assembly of claim 1 , wherein the curved bushing portion is disposed between the telescope jacket and the fixed jacket.
8. The steering column assembly of claim 1 , wherein the radial telescope bushing is disposed radially outward of an outer surface of the telescope jacket.
9. The steering column assembly of claim 1 , further comprising a telescope actuator assembly configured to telescopically move the telescope jacket relative to the fixed jacket.
10. The steering column assembly of claim 1 , wherein the post and the curved bushing portion are formed integrally as a single component to form the radial telescope bushing.
