A commercial vehicle suspension comprises: a pair of left and right axles (1, 1-1); and each left and right V arm (10, 10-1) fixed to one point and fixed to two points with a front and a rear V arm frame (3, 3), respectively. An axle joint (15) forming a v-shaped vertex of the left and the right V arm (10, 10-1) is fixated to the left and the right axle (1, 1-1), and a spherical ball fixating the axle joint (15) in the direction perpendicular to the left and the right axle (1, 1-1) is included in the axle joint (15). Therefore, a rotational moment due to forced constraint does not occurred in the left and the right V arm (10, 10-1) during vertical displacement of the left and the right axle (1, 1-1). More specifically, the axle joint (15) forms a screw fixing unit (A) and a welding fixing unit (A-1) in order to sufficiently secure durability of the left and the right V arm (10, 10-1). |
