The invention relates to a power electronic device with a dynamic vibration absorption function, an electric drive system and a vehicle. The power electronic device comprises a power electronic box body and a vibration absorption device. The electric drive system comprises a hub motor assembly, a power electronic device and a suspension. The suspension comprises a suspension shock absorber assembly, an upper control arm and a lower control arm, and the suspension shock absorber assembly is connected with the vehicle body and the lower control arm; a wheel of the hub motor assembly is connected with a hub motor, an upper control arm is connected with an upper connecting frame and a vehicle body, and a lower control arm is connected with a lower connecting frame and the vehicle body; and the power electronic box body is arranged on the upper connecting frame. Compared with the prior art, the self weight of the power electronic device is used as a vibration absorber to work, and the vehicle vertical negative effect caused by overlarge unsprung mass is improved on the premise that the weight of the whole vehicle is not increased; the working direction of the power electronic device serving as the dynamic vibration absorber is fixed, only vertical jolt is restrained, and wheel movement in other directions is not affected.

    本发明涉及一种具有动态吸振功能的电力电子装置、电驱系统及车辆,电力电子装置包括电力电子箱体和吸振装置;电驱系统包括轮毂电机总成、电力电子装置和悬架;悬架包括悬架减震器总成、上控制臂和下控制臂,悬架减震器总成连接车身和下控制臂;轮毂电机总成的车轮与轮毂电机连接,上控制臂与上联接架和车身相连,下控制臂与下联接架和车身相连;电力电子箱体安装在上联接架上。与现有技术相比,本发明具有利用电力电子装置的自身重量作吸振器而工作,在不增加整车重量的前提下改善了因簧下质量过大而引起的车辆垂向负效应;电力电子装置作为动力吸振器的工作方向固定,只对垂向的颠簸起抑制作用,不影响其他方向上的车轮运动等优点。
