Abstract
Official abstract text for this publication.
A drive pinion fastening assembly including a drive pinion, a pinion sleeve, an external spline, and a pinion fastener. The pinion sleeve is disposed on and engaged with the drive pinion. The external spline is formed on one of the drive pinion and the pinion sleeve for engaging the power transmission component. The pinion fastener is disposed on and engaged with the drive pinion. The pinion fastener militates against axial movement of the pinion sleeve with respect to the drive pinion.
First claim
Opening claim text (preview).
What is claimed is: 1. A drive pinion fastening assembly, comprising: a drive pinion; a pinion sleeve having a first end and a second end is disposed on and engaged with the drive pinion; wherein the second end of the pinion sleeve has a fastening recess formed in the second end of the pinion sleeve; an external spline formed on the drive pinion for engaging a power transmission component; and a pinion fastener having an inner peripheral edge and an outer peripheral edge, wherein the inner peripheral edge of the pinion fastener is disposed on and engaged with the drive pinion through an interference fit, wherein the pinion fastener is entirely disposed within the fastening recess on the second end of the pinion sleeve, wherein the pinion fastener militates against axial movement of the pinion sleeve with respect to the drive pinion. 2. The drive pinion fastening assembly according to claim 1 , wherein the external spline is formed on the drive pinion. 3. The drive pinion fastening assembly according to claim 2 , wherein the drive pinion further includes a threaded portion and the pinion sleeve includes a thread formed thereon for engaging the threaded portion of the drive pinion. 4. The drive pinion fastening assembly according to claim 2 , wherein the drive pinion further includes a locking spline portion for engaging the pinion fastener. 5. The drive pinion fastening assembly according to claim 4 , wherein a diameter of the external spline is less than a diameter of the locking spline portion. 6. The drive pinion fastening assembly according to claim 1 , wherein the pinion fastener is drivingly engaged with the pinion sleeve. 7. A drive pinion fastening assembly, comprising: a drive pinion including a locking spline portion; a pinion sleeve having a first end and a second end is disposed on and engaged with the drive pinion; wherein the second end of the pinion sleeve has a fastening recess formed in the second end of the pinion sleeve; an external spline formed on the drive pinion for engaging a power transmission component; and a pinion fastener having an inner peripheral edge and an outer peripheral edge, wherein the inner peripheral edge of the pinion fastener is disposed on and engaged with the locking spline portion of the drive pinion through an interference fit, wherein the pinion fastener is entirely disposed within the fastening recess on the second end of the pinion sleeve, wherein the pinion fastener militates against axial movement of the pinion sleeve with respect to the drive pinion. 8. The drive pinion fastening assembly according to claim 7 , wherein the drive pinion further includes a threaded portion and the pinion sleeve includes a thread formed thereon for engaging the threaded portion of the drive pinion. 9. The drive pinion fastening assembly according to claim 7 , wherein a diameter of the external spline is less than a diameter of the locking spline portion.
