Abstract: A shaft system for use in a vehicle is disclosed. The shaft system includes a tube. A constant velocity joint is secured to the tube. The shaft system also includes a plug arranged within the constant velocity joint wherein the plug is secured within the joint by a weld curl that is also used to secure the constant velocity joint to the tube.

Abstract: The invention relates constant velocity fixed universal joints A fixed constant-velocity ratio universal joint, comprising an outer joint part, an inner joint part, a ball cage and a plurality of balls. The ball cage is disposed between the inner and outer joint parts and includes windows in which respective balls are received and constrained such that their centers lie in a common plane. At least two opposing windows are wider than said outer joint part lands to accommodate receiving the lands during assembly. The cage includes substantially spherical inner and outer surfaces which engage the land surfaces on the inner and outer joint parts respectively. The ball cage also includes a relief groove between at least one pair of adjacent windows thereby providing a reduced circumference for the ball cage outer surface in the region of the groove.
