Abstract: A flex coupling assembly for coupling a first shaft to a second shaft of a shaft assembly. The flex coupling assembly decouples axial and torsional stiffness from bending stiffness of the shaft assembly, thereby dampening the transmission of noise and vibration between the first and second shafts. The flex coupling assembly includes an inner housing subassembly and an outer housing subassembly. The inner housing subassembly includes an inner housing and a resilient flex coupling disposed in an outer housing cavity of an outer housing of the outer housing subassembly. A retention member is fixed to an outer housing to retain the inner housing subassembly in the outer housing cavity. The inner and outer housing subassemblies can rotate and translate relative to a common axis, while the inner and the outer housings restrict bending between the inner and outer housing subassemblies, thereby restricting bending between the first and second shafts.

Abstract: An intermediate shaft assembly and method of assembly thereof. The intermediate shaft assembly includes a first shaft extending between a first end and a second end. The first shaft has a tubular wall portion with an inner surface bounding a hollow bore extending into said first end. The inner surface has a plurality of female splines and the tubular wall portion has at least one through opening. A second shaft extends between a coupling end and a connection end. The connection end has an outer surface sized for a clearance fit within the hollow bore. The outer surface has a plurality of male splines configured for an interdigitated fit with the female splines. The interdigitated fit establishes a clearance gap between the male splines and the female spines. A polymeric material at least partially fills the clearance gap and extends into the at least one through opening.

Abstract: A steering shaft assembly includes a male shaft having a plurality of teeth extending radially outwardly from a portion of the male shaft. The steering shaft assembly also includes a female shaft receiving a portion of the male shaft and fixed to the male shaft in a rotational direction, the male shaft axially moveable relative to the female shaft, the female shaft having an end portion and a body portion, wherein the end portion of the female shaft has an end wall thickness that is less than a body wall thickness of the body portion, the end portion curved radially inwardly to define a hard stop position during axial movement of the male shaft. An end of the plurality of teeth of the male shaft contact the curved end portion of the female shaft at the hard stop position.
