The cross beam 30 is located at the front of the longitudinal beam 10. This arrangement can save space on the rear side of the cross beam 30, thereby increasing the space in the middle of the sub-frame 100, thereby facilitating the installation of other components. Installed on the sub-frame 100, the suspension mounting bracket 20 on the left side is connected to the longitudinal beam 10 on the left side, and the suspension mounting bracket 20 on the right side is connected to the longitudinal beam 10 on the right side, so that the suspension can be set at the left and right ends of the sub-frame 100 through the suspension mounting brackets 20 on the left and right sides. This arrangement can make the suspension on the left side fit with the suspension mounting bracket 20 on the left side, and the suspension on the right side fit with the suspension mounting bracket 20 on the right side, so that the manufacturing tolerance between the suspension and the suspension mounting bracket 20 can be eliminated, and the firmness and reliability between the suspension and the suspension mounting bracket 20 can be improved, so as to facilitate the assembly of the suspension, and then the production efficiency of the sub-frame 100 can be improved.
