Joint assembly
A steer axle assembly for an axle including a first steering component, a second steering component, and a movable joint assembly coupled to the first steering component and the second steering component. The movable joint is configured for axial movement and rotational movement to provide for relative movement between the first and second steering components. The first steering component is produced from a first material having a first coefficient of thermal expansion. The second steering component is produced from a second material having a second coefficient of thermal expansion, wherein the second coefficient of thermal expansion is different from the first coefficient of thermal expansion.

a first joint assembly coupled to the first steering component and the second steering component, wherein the first joint assembly is configured for axial movement and rotational movement to provide for relative movement between the first and second steering components.
2. The steer axle assembly of claim 1 , wherein the first steering component is a steering yoke and the second steering component is a steering knuckle.
3. The steer axle assembly of claim 1 , wherein the first steering component is produced from a steel material and the second steering component is produced from a non-steel material.
4. The steer axle assembly of claim 1 , wherein the first joint assembly includes a cylindrically shaped socket coupled to one of the first steering component and the second steering component, wherein the socket has a spherical inner surface.
5. The steer axle assembly of claim 1 , wherein the first joint assembly includes a support member movably coupled to one of the first steering component and the second steering component, the support member having a cavity formed therein.
6. The steer axle assembly of claim 5 , wherein the first joint assembly further includes a movable member at least partially disposed in the cavity of the support member.
7. The steer axle assembly of claim 6 , further comprising a sleeve coupled to the first steering component, where the sleeve is configured to receive at least a portion of the movable member.
8. The steer axle assembly of claim 6 , wherein the first joint assembly further includes a seal disposed adjacent at least one of the support member and the movable member.
9. The steer axle assembly of claim 1 , wherein the first joint assembly includes at least one fluid device to provide a flow of a fluid to within the first joint assembly.
10. The steer axle assembly of claim 1 , wherein the first joint assembly includes a dampener.
11. An axle assembly, comprising:
a first connecting component produced from a first material having a first coefficient of thermal expansion, wherein the first connecting component includes at least one aperture formed therein;
a second connecting component produced from a second material having a second coefficient of thermal expansion, wherein the second coefficient of thermal expansion is different from the first coefficient of thermal expansion, and wherein the second connecting component includes at least one aperture formed therein; and
a first joint assembly coupled to the first connecting component and the second connecting component, wherein the first joint assembly is configured for axial movement and rotational movement to provide for relative movement between the first and second connecting components caused by the different coefficients of thermal expansion, and wherein the first joint assembly includes a socket at least partially received in the at least one aperture of the second connecting component, a support member having a cavity formed therein and at least partially disposed in the socket, and a movable member at least partially disposed in the cavity of the support member.
12. The axle assembly of claim 11 , wherein the first connecting component is produced from a steel material and the second connecting component is produced from a non-steel material.
13. The axle assembly of claim 11 , further comprising a sleeve coupled to the first steering component, where the sleeve is configured to receive at least a portion of the movable member.
14. The axle assembly of claim 13 , wherein the sleeve has a tapered aperture formed therethrough.
15. The axle assembly of claim 11 , wherein the first joint assembly includes at least one fluid device to provide a flow of a fluid to at least one of the socket, the support member, and the movable member.
16. The axle assembly of claim 11 , wherein the first joint assembly includes a dampener disposed between the socket and the support member.
17. The axle assembly of claim 11 , wherein the first joint assembly includes a seal disposed adjacent the socket, the support member, and the movable member.
18. The axle assembly of claim 11 , wherein the support member is in sliding engagement with the second connecting component to allow an axial movement of the support member along a center axis thereof in both a first direction and a second direction.
19. The axle assembly of claim 11 , wherein a portion of the movable member is in sliding engagement with the support member to permit rotational movement of the movable member therewithin.
20. The axle assembly of claim 11 , further comprising a second joint assembly coupled to the first connecting component and the second connecting component, wherein the first joint assembly is configured for at least one of axial movement and rotational movement to provide for relative movement between the first and second connecting components caused by the different coefficients of thermal expansion.
