Cross groove type constant velocity joint with composite groove patterns

A constant velocity joint for a drive system comprising:

• an outer joint member having a plurality of inwardly facing outer ball grooves, the outer ball grooves consisting of a first group of grooves, each groove of which having a non-linear groove shape formed with two or more groove segments having different skew angles relative to an axis of rotation of outer joint member, and a second group of grooves, each groove of which having a non-linear groove shape formed with two or more groove segments having different skew angles relative to an axis of rotation of outer joint member;
• an inner joint member disposed inside the outer joint member and having a plurality of outwardly facing inner ball grooves consisting of a first group of grooves, each groove of which having a non-linear groove shape formed with two or more groove segments having different skew angles relative to an axis of rotation of outer joint member, and a second group of grooves, each groove of which having a non-linear groove shape formed with two or more groove segments having different skew angles relative to an axis of rotation of inner joint member, each inner ball groove of the inner joint member being coupled with a corresponding outer ball groove of the outer joint member generally in crossed pair;
• a plurality of torque transfer balls which are guided by the ball groove faces of outer and inner joint member;
• and
• a cage having circumferentially displaced windows to accommodate the balls therein.
