Abstract:
1. A sliding splined slip joint for use in a vehicle driveshaft comprising: a tubular insert formed from a tubular body having inner and outer cylindrical surfaces, said tubular insert comprising axially-spaced circumferentially-aligned first and second annular arrays of axially-extending splines, said splines being radially-inwardly deformed from said inner cylindrical surface of said tubular body such to define corresponding recesses within said outer cylindrical surface of said tubular body, and such to define an annular pocket between said inner cylindrical surface of said tubular body and said first and second annular arrays of splines, said pocket extending radially-outward from and located between said first and second annular arrays of splines maintaining a substantially constant depth and width around an inner surface of said insert; a female tubular driveshaft member comprising at least one annular array of radially-inwardly extending magnetic pulse formed crimps, said crimps being complementary to and slidably engaged within corresponding said recesses defined by said first and second annular arrays of splines on said tubular insert, said tubular insert fixed within said female tubular driveshaft member by a magnetic pulse welding or magnetic forming process; a male driveshaft member having an annular array of radially-outwardly extending splines slidably engaged with said splines of said tubular insert, wherein said male driveshaft member is located within said tubular insert.
