The invention discloses an auxiliary frame, an arrangement structure of the auxiliary frame and a dual-motor assembly and a vehicle. The auxiliary frame comprises at least two first longitudinal beams extending in the first direction, a first cross beam, a second cross beam and a third cross beam, the first cross beam, the second cross beam and the third cross beam extend in the second direction and are sequentially arranged in the first direction, and the second cross beam and the third cross beam are located between the two first longitudinal beams and define an annular inner frame with the two first longitudinal beams. A notch is formed in the second cross beam; the first cross beam is located on the side, away from the third cross beam, of the second cross beam and connected with the second cross beam or the first longitudinal beam, and the extending range of the first cross beam in the second direction covers the notch. According to the auxiliary frame, under the conditions that the length size of the auxiliary frame is basically not increased and the battery arrangement space is not extruded and occupied, the overall strength of the auxiliary frame is improved, the anti-torque performance of the auxiliary frame is improved, the power specification of a driving motor which can be carried by the auxiliary frame is improved, and the requirement that the auxiliary frame carries a high-power double-motor assembly is met.
本申请公开了一种副车架、副车架和双电机总成的布置结构及车辆。该副车架包括至少两个沿第一方向延伸的第一纵梁,以及均沿第二方向延伸并沿第一方向依次排列的第一横梁、第二横梁和第三横梁,第二横梁和第三横梁均位于两个第一纵梁之间并与两个第一纵梁围合成环形内框;第二横梁上设置有缺口;第一横梁位于第二横梁远离第三横梁的一侧,第一横梁与第二横梁或第一纵梁相连,且第一横梁在第二方向上的延伸范围覆盖缺口。该副车架能够在基本不增大副车架自身的长度尺寸而不挤压占用电池布置空间的情况下,提高副车架的整体强度,提高副车架的抗扭矩性能,提高所能搭载的驱动电机的功率规格,满足副车架搭载大功率双电机总成的需求。
