Constant velocity joint assembly

A constant velocity joint assembly comprising:

• a first constant velocity joint comprising a first shaft, a first inner race coupled to the first shaft, a first outer race accommodating the first inner race, and a first ball disposed between the first inner race and the first outer race;
• a second constant velocity joint disposed opposite the first constant velocity joint, the second constant velocity joint comprising a second shaft, a second inner race coupled to the second shaft, a second outer race accommodating the second inner race, and a second ball disposed between the second inner race and the second outer race;
• and
• a link comprising a plate-shaped portion disposed between the first outer race and the second outer race, a first coupling portion configured to allow an end portion of the first shaft to be engaged therewith, and a second coupling portion configured to allow an end portion of the second shaft to be engaged therewith,
• wherein the end portion of the first shaft has a portion in direct contact with the first coupling portion during articulating motion, and the portion in direct contact with the first coupling portion is formed in a spherical shape, and
• wherein the constant velocity joint assembly satisfies a following parameter relationship:
