The invention relates to the technical field of electric commercial vehicles, and particularly discloses a chassis assembly of an electric commercial vehicle. A middle frame is connected between a front frame and a rear frame, the front frame is located on the front side of the middle frame, the rear frame is located on the rear side of the middle frame, and the middle frame and the rear frame are located at the same vertical height; the vertical height of the front frame is lower than that of the middle frame, the electric commercial vehicle comprises a cab, the cab is fixedly installed on the front frame, and the power battery pack is fixedly installed on the middle frame and located below the middle frame. According to the arrangement, the main frame is of a stepped structure which is low in front and high in rear, the cab is arranged on the front frame, and the power battery pack is hung at the bottom of the middle frame, so that the gravity center of the whole vehicle is effectively reduced, the rollover risk is reduced, the safety performance is improved, meanwhile, the effective utilization space of the main frame is further released, and the adaptability of chassis assembly refitting is improved.
本发明涉及电动商用车技术领域,具体公开了一种电动商用车的底盘总成,其中,中车架连接于前车架与后车架之间,前车架位于中车架的前侧,后车架位于中车架的后侧,中车架与后车架处于同一竖直高度,前车架的竖直高度低于中车架的竖直高度,电动商用车包括驾驶室,驾驶室固定安装于前车架上,动力电池组固定安装于中车架,并位于中车架的下方。如此设置,主车架采用前低后高的阶梯式结构,驾驶室设置于前车架上,中车架底挂动力电池组,有效降低整车重心,降低侧翻风险,提高安全性能,同时进一步释放主车架的有效利用空间,提高底盘总成改装的适应性。
