Abstract

A steering knuckle assembly provides a tapered roller bearing on the bottom and a needle bearing on the top of a king pin. A spring cap preloads the tapered roller bearing. The king pin includes a step on the upper portion to transfer the spring cap preload force to the top of an axle beam.

Claims (36)

1. A king pin arrangement comprising:

a support structure comprising an upper cavity and a lower cavity;

a needle bearing within said upper cavity;

a tapered roller bearing within said lower cavity;

a king pin mounted within said needle bearing and said tapered roller bearing for rotation about an axis, a step defined in said king pin; and

a spring cap mounted within said upper cavity, said spring cap exerting a force upon said king pin, said step for transferring said force to an axle beam.

2. The king pin arrangement as recited in claim 1 , wherein said upper cavity and said lower cavity are threaded.

3. The king pin arrangement as recited in claim 1 , further comprising an adjustment nut mounted within said lower cavity.

4. The king pin arrangement as recited in claim 3 , wherein said adjustment nut supports said tapered roller bearing.

5. The king pin arrangement as recited in claim 1 , further comprising a spacer between said tapered roller bearing and the location of an axle beam which will surround said king pin.

6. The king pin arrangement as recited in claim 1 , wherein said support structure comprises a steerable knuckle.

7. The king pin arrangement as recited in claim 1 , wherein said tapered roller bearing is tapered in a direction moving away from said upper cavity.

8. The king pin arrangement as recited in claim 1 , further comprising a spring cap mounted within said upper cavity, said spring cap exerting a force upon said king pin toward said tapered roller bearing.

9. The king pin arrangement as recited in claim 1 , wherein an upper segment of said king pin is of a larger diameter than a king pin segment which is to be received into the axle beam.

10. A steerable knuckle assembly comprising:

a steering knuckle comprising an upper cavity and a lower cavity;

a needle bearing within said upper cavity;

a tapered roller bearing within said lower cavity;

a king pin mounted within said needle bearing and said tapered roller bearing for rotation about an axis, a step defined in said king pin; and

a spring cap mounted within said upper cavity, said spring cap exerting a force upon said king pin, said step for transferring said force to an axle beam.

11. The steerable knuckle assembly as recited in claim 10 , wherein said upper cavity and said lower cavity are threaded.

12. The steerable knuckle assembly as recited in claim 10 , further comprising an adjustment nut mounted within said lower cavity.

13. The steerable knuckle assembly as recited in claim 10 , further comprising a spacer between said tapered roller bearing and an axle beam.

14. The steerable knuckle assembly as recited in claim 10 , wherein said tapered roller bearing is tapered in a direction away from said upper cavity.

15. The steerable knuckle assembly as recited in claim 10 , wherein an upper segment of said king pin is of a larger diameter than a king pin segment which is to be received into the axle beam.

16. A king pin arrangement comprising:

a support structure comprising an upper cavity and a lower cavity;

a needle bearing within said upper cavity;

a tapered roller bearing within said lower cavity; and

a king pin mounted within said needle bearing and said tapered roller bearing for rotation about an axis, an upper segment of said king pin received within said needle bearing, said upper segment of said king pin of a larger diameter than a king pin segment which is received into said tapered roller bearing.

17. A steerable knuckle assembly comprising:

a steering knuckle comprising an upper cavity and a lower cavity;

a needle bearing within said upper cavity;

a tapered roller bearing within said lower cavity;

a king pin mounted within said needle bearing and said tapered roller bearing for rotation about an axis, an upper segment of said king pin received within said needle bearing, said upper segment of said king pin is of a larger diameter than a king pin segment which is received into said tapered roller bearing; and

a spring cap mounted within said upper cavity, said spring cap exerting a force upon said king pin.
