The application relates to a pure electric truck chassis adopting a through longitudinal beam frame, which belongs to the technical field of automobile manufacturing. The chassis comprises a chassis frame, a battery bracket, and a power battery pack. The chassis frame comprises a left longitudinal beam and a right longitudinal beam which are parallel to each other and arranged at intervals, a plurality of cross beams connected between the left longitudinal beam and the right longitudinal beam, and a front axle and a rear axle connected to the bottoms of the left longitudinal beam and the rightlongitudinal beam. The battery bracket comprises a front bracket which is fixedly arranged between the left longitudinal beam and the right longitudinal beam and is arranged above the front axle, a middle bracket which is fixedly arranged between the left longitudinal beam and the right longitudinal beam and is arranged between the front axle and the rear axle, and side brackets which are fixedlyarranged on the outer sides of the left longitudinal beam and the right longitudinal beam; and the power battery pack comprises a front power battery fixedly arranged in the front bracket and a middle power battery fixedly arranged in the middle bracket. Compared with the prior art, the pure electric truck chassis has the following advantages: modification adaptability is better, more power assemblies of the rear axle are selected, and due to the fact that the power battery pack is compact in arrangement, the total volume and the electric quantity of the power battery pack are relatively larger, and the cruising ability of a truck is improved.
本申请涉及一种采用贯通纵梁车架的纯电动卡车底盘,属于汽车制造技术领域,包括:底盘车架,其包括相互平行且间隔设置的左纵梁和右纵梁、连接在左纵梁和右纵梁之间的多根横梁、连接在左纵梁和右纵梁底部的前桥和后桥;电池托架,其包括固设于左纵梁和右纵梁之间且位于前桥上方的前部托架、固设于左纵梁和右纵梁之间且位于前桥和后桥之间的中部托架、固设于左纵梁和右纵梁外侧的侧部托架;动力电池包,其包括固设于前部托架内的前部动力电池、固设于中部托架内的中部动力电池。本申请改装适应性更好,后桥的动力总成的选择形式更多,由于动力电池包布置紧凑,动力电池包的总体积和电量相对更大,提高卡车的续航能力。
