PURPOSE: A lower arm with a welding-fixed hollow connector for a ball joint assembly is provided to fix a connector to a ball stud by welding without using bolts and nuts, thereby making the connection simple and reducing the weight of a knuckle coupling end. CONSTITUTION: A lower arm with a welding-fixed hollow connector for a ball joint assembly includes first and second vehicle body coupling ends and a knuckle coupling end. The first and second vehicle body coupling ends(8,9) are assembled with bushes and located at an interval to be connected to a chassis frame. The knuckle coupling end(10) is positioned on the other side of the first and second vehicle body coupling ends and welded with the hollow connector. A coupling shaft(5a) of a ball stud(5) penetrates through the knuckle coupling end from a knuckle(2) mounted on an axle assembly(1), and a nut(6) is coupled to the protruding part of the coupling shaft. |
