Abstract: A constant velocity joint includes first and second shafts, inner and outer members and a constraining unit. The first shaft has a first yoke attached thereto and the second shaft has a second yoke, smaller than the first yoke, attached thereto. The outer member is pivotally connected to the first yoke about a first rotation axis which is perpendicular to the axis of the first shaft. The inner member is pivotally connected to the second yoke about a second rotation axis which is perpendicular to the axis of the second shaft. The outer member is pivotally connected to the inner member about a third rotation axis which is perpendicular to both the first and second rotation axes. All of the five axes intersect at a joint center point. The constraining unit constrains the third rotation axis to continuously lie generally within the homokinetic plane of the joint.
