Constant velocity joint assembly integrated with wheel hub unit

A constant velocity joint assembly integrated with a wheel hub device, the assembly comprising:

• an internal race coupled to an end portion of a driveshaft;
• a plurality of joint balls rotatably mounted in the internal race;
• a hub housing accommodating and being coupled to the internal race holding the joint balls therein, wherein the hub housing includes a bearing mounted to an external circumferential surface of the hub housing, the hub housing provided to perform roles of both an external race and the wheel hub device, and wherein the bearing includes an internal ring, an external ring and bearing balls,
• wherein a knuckle carrier is fixed to the external ring of the bearing,
• wherein rows for supporting the bearing balls are accommodated on the hub housing and the internal ring of the hub bearing, respectively,
• wherein the bearing balls are mounted onto the external ring and in the rows of the hub housing and the internal ring, and
• wherein a lock nut is coupled to the hub housing and engaged to the internal ring to apply a preload to the internal ring,
• a lock ring fixedly coupled to the hub housing while abutting against a side surface of the lock nut;
• and
