The invention provides a dual-motor direct drive system and a vehicle. The dual-motor direct drive system comprises a shell, two motors and two planetary speed reduction mechanisms, the two planetary speed reduction mechanisms are located in the shell, the opposite sides of the two planetary speed reduction mechanisms are each provided with an input end and an output end, the two motors are located on the two sides of the shell and connected with the two input ends in a one-to-one correspondence mode, and the two output ends are both used for being connected with wheels; each planetary reducing mechanism comprises a first simple planet row, a second simple planet row and a third simple planet row, a planet carrier of the first simple planet row is fixedly connected with a sun gear of the second simple planet row, and the output end is located on the planet carrier of the second simple planet row and penetrates through the input end; the two first simple planet rows are located on the two sides of the two second simple planet rows. The dual-motor direct drive system is more compact in structure, smaller in axial length and easier to arrange.

    本文提供了一种双电机直驱系统和车辆。双电机直驱系统包括壳体、两个电机和两个行星减速机构,两个行星减速机构位于壳体内,两个行星减速机构相背的一侧均设有输入端和输出端,两个电机位于壳体的两侧、并与两个输入端一一对应连接,两个输出端均用于连接车轮;每个行星减速机构包括:第一简单行星排,输入端位于第一简单行星排的太阳轮上;和第二简单行星排,第一简单行星排的行星架与第二简单行星排的太阳轮固定连接,输出端位于第二简单行星排的行星架上、并穿过输入端;其中,两个第一简单行星排位于两个第二简单行星排的两侧。该双电机直驱系统,其结构更紧凑,轴向长度更小,更容易布置。
