The invention relates to a vehicle axle 1 and two longitudinal ties 3 vertically arranged along the vehicle; the longitudinal tie comprises a link portion 3a connected with a vehicle body and a link portion 3b connected with vehicle wheels; an anti-bending crossbeam 2 is easy to be twisted so as to mutually connect the two longitudinal ties 3 in a transverse direction of the vehicle; the crossbeam2 is formed by a single-wall metal section bar 5; a cross section of the metal section bar has a bottom plate 7 and two side plates 8a and 8b; an end section 6 is formed by a reinforced plate 4; an edge9 of the reinforced plate 4 is connected with the metal section bar 5 and/or the longitudinal ties 3 in an annular manner; in addition, the reinforced plate 4 is connected with 11 and the bottom plate 7 of the metal section bar 5 in a dotted manner in an end portion 10 of the cross beam side. The vehicle axle uses the axle 1 to greatly improve driving performance of the vehicle through adding the reinforced plate 4; stress in the end portion 10 of the cross beam2 is not limited in a local portion, and well distributed to the whole area.
