The invention discloses a power system and an electric truck with the same. The power system comprises: a direct drive motor and a transmission assembly, the direct drive motor comprises a shell and adriving unit, the driving unit comprises a stator iron core assembly, a rotor iron core assembly, a rack and a gear; the stator iron core assembly and the rotor iron core assembly are both arranged in the shell and are oppositely arranged in the shell; the rotor iron core assembly can move relative to the shell and the stator iron core assembly, the rack is arranged on the rotor iron core assembly, the gear extends out of the shell and is meshed with the rack, the transmission assembly is provided with an input shaft and an output shaft, the input shaft and the gear rotate synchronously, andthe output shaft and the input shaft are in transmission and used for outputting power. According to the electric truck, the direct drive motor is used for driving, a transmission shaft and a gearboxcan be omitted, meanwhile, the power system can be installed on a vehicle frame in a suspended mode, and therefore the unsprung mass is reduced, the reliability of the drive system is guaranteed, thespace utilization rate of the whole truck can be increased, and the integration degree of the electric truck can be high.
本发明公开了一种动力系统和具有其的电动卡车,动力系统包括:直驱电机和传动组件,直驱电机包括:壳体和驱动单元,驱动单元包括:定子铁芯总成、动子铁芯总成、齿条和齿轮,定子铁芯总成和动子铁芯总成均设置于壳体内且在壳体内相对设置,动子铁芯总成相对壳体和定子铁芯总成可运动,齿条设置于动子铁芯总成上,齿轮伸出壳体且与齿条啮合,传动组件具有输入轴和输出轴,输入轴与齿轮同步转动,输出轴与输入轴传动且用于输出动力。通过使用直驱电机进行驱动,可以省去传动轴和变速箱,同时可以将动力系统通过悬置安装在车架上,从而减小簧下质量保证了驱动系统的可靠性,以及可以整车的空间利用率,可以使得电动卡车的集成度高。
