Slip Yoke Assembly For Automotive Drive Train

摘要

Automotive drive shafts having slip yoke assemblies that are designed and configured to transmit torque and allow for axial movement while also minimizing driveline vibrations. In some embodiments, the slip yoke assemblies may include one or more bearings that minimize angular misalignment and resist drive shaft bending forces. In some embodiments, the bearings may include a pair of precision mating diameters on a yoke shaft and splined sleeve. In yet other embodiments, the slip yoke assembly may include internal rod wipers to seal out environmental contaminants and retain lubricants.

主权项

1. A slip yoke assembly for use in an automobile driveshaft comprising:
an outer sleeve having an inner lumen and an internal spline located in a portion of said inner lumen; a yoke shaft slidably disposed within said inner lumen and configured for movement over a working stroke between a fully-inserted position and a design-maximum-extended position, said yoke shaft having an external spline configured to engage said internal spline to form a splined joint; and at least one bearing surface disposed between the outer sleeve and yoke shaft and spaced from the splined joint, said bearing surface configured and dimensioned to resist angular misalignment between said splined sleeve and said yoke shaft.
