Abstract
A motor vehicle shaft assembly has a shaft extending along a longitudinal axis between opposite ends, with the shaft having a male spline adjacent at least one of the opposite ends, and a housing having a through bore extending about the longitudinal axis, with the through bore having a female spline configured for meshed engagement with the male spline to prevent relative torsional movement between the shaft and the housing. At least one of the male and female splines includes a tapered spline extending in oblique relation to the longitudinal axis.
Claims5
A constant velocity joint assembly, comprising:
- a half shaft extending along a longitudinal axis between opposite ends and having a male spline adjacent at least one of said opposite ends;
- and
- a constant velocity joint having an inner race, an outer race and a plurality of rollers between said inner race and said outer race, said inner race having a through bore extending about said longitudinal axis with a female spline configured in meshed engagement with said male spline of said half shaft to prevent relative rotation between said half shaft and said inner race,
- wherein each of said male spline and said female spline has a tapered minor diameter.
