Constant velocity joint

A constant velocity joint comprising:

• a joint outer part having a connecting portion and an opening portion, the opening portion having a plurality of axially extending grooves, each groove providing an outer ball raceway;
• a joint inner part having a plurality of axially extending grooves, each groove of the joint inner part providing an inner ball raceway, each one of the outer ball raceways and a separate one of the inner ball raceways forming one of a plurality of raceway pairs;
• and
• a plurality of balls, each ball being disposed within a separate one of the plurality of raceway pairs;
• wherein the outer ball raceway and the inner ball raceway of each raceway pair define a region that, in a cross-section with respect to a longitudinal axis of each groove, is conceptually divided into four quadrants;
• wherein the outer ball raceway is disposed in a first quadrant and a second quadrant and the inner ball raceway is disposed in a third quadrant and a fourth quadrant;
• wherein with a torque transmission of the constant velocity joint in a first direction, each ball has two simultaneous contact points in the first quadrant and/or two simultaneous contact points in the third quadrant;
• and/or
• wherein with a torque transmission of the constant velocity joint in a second direction, each ball has two simultaneous contact points in the second quadrant and/or two simultaneous contact points in the fourth quadrant.
