Each welded joint system may include a sleeve that is bonded to an end of the composite tube and a joint assembly that is welded to the sleeve.

A torque tube assembly includes a torque tube, and a fitting attached to the torque tube by a first EMF joint and by a second EMF joint. The first EMF joint comprises a first plurality of torque lands formed proximate a first end of the torque tube and a first plurality of fitting lands formed proximate a first end of the fitting. The second EMF joint comprises a second plurality of torque lands formed distal to the first end of the torque tube and a second plurality of fitting lands formed distal to the first end of the fitting.

A drive train connector assembly includes a first connecting structure and a second connecting structure. The first connecting structure has an attachment protrusion with first and second edges. The first edge extends in a first direction. The second edge extends in a second direction. Both directions are perpendicular to the rotational axis. The first and second directions define a first acute angle therebetween. The second connecting structure defines recessed area. The attachment protrusion fits into the recessed area. The recessed area defines third and fourth edges. The third edge extends in a third direction and the fourth edge extends in a fourth direction. The third direction and the fourth direction define a second acute angle. With the attachment protrusion installed within the recessed area the first and third edges are parallel to one another and the second and fourth edges are parallel to one another.

A vehicle steering device includes a positioning clip configured to align a pinion shaft with a joint portion of a steering shaft, wherein the pinion shaft includes a torsion bar and a tubular member having the torsion bar inserted thereinto, an upper end of the torsion bar is axially further away from the joint portion than an upper end of the tubular member, the positioning clip includes an inserted portion to be inserted into the tubular member, and a gap between the inserted portion and the tubular member is sealed.

A joint assembly (10) including a female member (12), a male member (40) and a retaining member (60). The female member has a first axial end (18), a second axial end (20) and a cylindrical body portion (14) extending between the first axial end and the second axial end having a splined radially inner surface. The male member has a first axial end portion (42), a second axial end portion (46), and a splined tubular portion (44) extending between the first axial end portion and the second axial end portion. The retaining member (60) includes an annular portion and a plurality of attachment features defining an aperture. The second axial end portion of the male member has a circumferential groove (48) on the outer surface thereof. The second axial end portion of the male member extends through the aperture of the retaining member and the attachment features extend into the groove of the male member.

A shaft-hub connection system with angular play for bidirectional transmission of driving torque, comprising a shaft, a hub provided with a hole inside which the shaft is accommodated, and elements for connection which are interposed between the hub and said shaft. The connection elements comprise at least one functional assembly which comprises a slot in which a corresponding coupling element is accommodated so that it can move and is adapted to assume alternately a first position, in which it is retracted within the slot, a second position, in which it protrudes partially with respect to it along a first orientation, and a third position, in which it protrudes partially with respect to it along a second orientation, elastic compression elements interposed between the slot and the coupling element, a first seat and a second seat for the abutment of the coupling element.

A steering assembly includes a pinion shaft. The steering assembly also includes a clamp yoke defining a central opening for axially receiving the pinion shaft and defining a counter bore for receiving a fastener that couples the pinion shaft to the yoke. The steering assembly further includes a blocking assembly fixed to the clamp yoke. The blocking assembly includes a resilient member having a first leg, a second leg and a connecting end. The blocking assembly also includes a blocking member coupled to the first leg and the second leg of the resilient member, the blocking member rotatable between a blocking position and a non-blocking position, the blocking position blocking the counter bore in an initial position and rotatable upon contact with the pinion shaft to be clear of the counter bore in the non-blocking position.

A yoke for a transfer case output shaft includes a hollow cylindrical sleeve portion and a disc-shaped flange portion extending radially from an outer portion of the hollow cylindrical sleeve portion. The hollow cylindrical sleeve portion includes a plurality of inwardly extending splines configured to engage outwardly extending splines of the transfer case outlet shaft. The disc-shaped flange portion has a plurality of fastener openings therethrough that correspond to fastener openings through a flange portion of a companion flange. A notch is formed through the hollow cylindrical sleeve portion at an open end of the hollow cylindrical sleeve portion. A groove is formed within the inner surface of the hollow cylindrical sleeve and extends about a rotation axis of the hollow cylindrical sleeve portion. A C-clip is received within the groove for restricting axial movement along the rotation axis and includes open ends that are received within the notch.

A coupling assembly having a first member drivingly connected to a second member via one or more third members. A first shaft is drivingly connected to the first member and a second shaft is drivingly connected to the second member. The second member includes a flange portion having one or more seating portions on a first end portion of the flange. Additionally, the flange has one or more flange portion attachment apertures extending from the seating portions to a second end portion of the flange. An increased diameter portion of the second shaft has one or more increased diameter portion apertures extending from a first end portion to a second end portion. The flange portion apertures and the increased diameter portion apertures have a center-line with an angle from an axial center-line of the assembly. Additionally, the seating portions have an angle relative to a radial center-line of the assembly.
