STEERING SHAFT ASSEMBLY CONNECTION
A steering assembly includes a steering shaft assembly having an end and a rack-and-pinion mechanism including a pinion assembly coupled to the end of the steering shaft assembly. The pinion assembly includes a bore extending between a first end of the pinion assembly and a second end of the pinion assembly. A fastener secures the end of the steering shaft assembly to the pinion assembly such that at least one of the end of the steering shaft assembly and the fastener is at least partially received within the bore in the pinion assembly.
1 . A steering assembly comprising:
a steering shaft assembly having an end;
a rack-and-pinion mechanism including a pinion assembly coupled to the end of the steering shaft assembly, the pinion assembly including a bore extending between a first end of the pinion assembly and a second end of the pinion assembly; and
a fastener securing the end of the steering shaft assembly to the pinion assembly, at least one of the end of the steering shaft assembly and the fastener being at least partially received within the bore in the pinion assembly.
2 . The steering assembly of claim 1 , wherein the pinion assembly includes a pinion housing and a pinion supported within the pinion housing, the bore in the pinion assembly being formed in the pinion.
3 . The steering assembly of claim 1 , wherein the end of the steering shaft assembly includes a shaft, the shaft received in the bore of the pinion assembly and extending from the second end of the pinion assembly such that the fastener is secured to the portion of the shaft extending from the second end of the pinion assembly.
4 . The steering assembly of claim 3 , wherein the shaft has a threaded end and the fastener is a nut secured on the threaded end of the shaft.
5 . The steering assembly of claim 3 , wherein the shaft is configured to transfer torque to a pinion of the pinion assembly.
6 . The steering assembly of claim 3 , wherein the shaft is configured to act as a pinion for the rack-and-pinion mechanism such that the pinion assembly does not include any integral pinion.
7 . The steering assembly of claim 1 , wherein the end of the steering shaft assembly includes a yoke coupled with the first end of the pinion assembly, and wherein the fastener extends through the bore of the pinion assembly and into engagement with the yoke.
8 . The steering assembly of claim 7 , wherein the fastener is inserted into the bore of the pinion assembly from the second end of the pinion assembly.
9 . The steering assembly of claim 7 , wherein the yoke includes a threaded portion, and wherein the fastener is a bolt having a threaded end received in the threaded portion of the yoke.
10 . The steering assembly of claim 7 , wherein at least one of the yoke and the pinion assembly includes an anti-rotation feature at an interface between the yoke and the first end of the pinion assembly.
11 . A method of connecting a steering shaft assembly to a pinion assembly of a rack-and-pinion mechanism, the steering shaft assembly having an end and the pinion assembly having a first end for receiving the end of the steering shaft assembly and a second end opposite the first end, the method comprising:
positioning the end of the steering shaft assembly to be received by the first end of the pinion assembly; and
securing the end of the steering shaft assembly relative to the pinion assembly using a fastener that is secured from the second end of the pinion assembly.
12 . The method of claim 11 , wherein securing the end of the steering shaft assembly using a fastener is achieved without manually securing the end of the steering shaft assembly adjacent the first end of the pinion assembly.
13 . The method of claim 11 , further comprising:
inserting the end of the steering shaft assembly through a bore extending between the first and second ends of the pinion assembly such that the end of the steering shaft assembly extends out of the pinion assembly adjacent the second end; and
securing a fastener to the end of the steering shaft assembly extending out of the pinion assembly adjacent the second end.
14 . The method of claim 13 , further comprising inserting the end of the steering shaft assembly through the bore in the pinion assembly until a shoulder of the steering shaft assembly abuts the first end of the pinion assembly.
15 . The method of claim 13 , wherein the pinion assembly includes a pinion defining the bore, and wherein inserting the end of the steering shaft assembly through the bore provides a torque transferring relation between the end of the steering shaft assembly and the pinion.
16 . The method of claim 13 , wherein inserting the end of the steering shaft assembly through the bore provides an intermeshing relation between the rack-and-pinion mechanism and the end of the steering shaft assembly such that the end of the steering shaft assembly functions as the pinion of the rack-and-pinion mechanism.
17 . The method of claim 11 , wherein the end of the steering shaft assembly includes a yoke configured to be received by the first end of the pinion assembly, and wherein securing the end of the steering shaft assembly relative to the pinion assembly includes inserting the fastener into the bore in the pinion assembly from the second end of the pinion assembly and into engagement with the yoke.
18 . The method of claim 17 , wherein the yoke includes a threaded portion, and wherein the fastener is a bolt having a threaded end received in the threaded portion of the yoke.
19 . The method of claim 18 , further comprising:
securing the yoke against relative rotation with the pinion assembly.
20 . The method of claim 11 , wherein the fastener is a threaded fastener, and wherein the threaded fastener is tightened from the second end of the pinion assembly.
