The invention discloses a new energy 4200 wheelbase commercial vehicle frame, which belongs to the technical field of frames, and comprises a cross beam assembly, a longitudinal beam assembly, a plate spring support assembly, a cab support assembly, a driving support assembly and a connecting assembly. The frame composed of the cross beam assembly and the longitudinal beam assembly is of a structure with the narrow front portion and the wide rear portion, the front end is narrowed, enough space is provided for front wheel steering, the width of the middle of the frame is increased, arrangement of parts of an electric control system is facilitated, and the upper wing face and the lower wing face between the cross beam assembly and the longitudinal beam assembly are connected, so that the torsional rigidity of the frame is improved; the longitudinal beam middle reinforcing plate and the longitudinal beam rear reinforcing plate are additionally arranged on the inner side of the left longitudinal beam and the inner side of the right longitudinal beam to reinforce the local part of the frame, large loads brought by parts such as a battery pack can be borne, and the local strength of the frame is improved. The left longitudinal beam and the right longitudinal beam are produced through numerical control punching, mounting holes can be added according to the assembly requirement, a segmented die is adopted for forming, six segments are divided, and the length of the frame is adjusted according to the customer requirement.
本发明公开了一种新能源4200轴距商用车车架,属于车架技术领域,由横梁组件、纵梁组件、板簧支撑组件、驾驶室支撑组件、驱动支撑组件和连接组件组成。本发明通过设置由横梁组件和纵梁组件组成的车架,为前窄后宽结构,前端减窄给前轮转向提供足够空间,车架中部宽度增加有利于电控系统零件布置,横梁组件和纵梁组件之间上下翼面连接有利于增大车架抗扭刚度,在左纵梁和右纵梁的内侧增加纵梁中加强板和纵梁后加强板,对车架局部进行加强,可以承受电池包等零件带来的较大载荷,提高车架局部强度;通过左纵梁和右纵梁生产采用数控冲孔,可以适应装配需求增加安装孔,成型采用分段模,共分六段,适应客户需求调整车架长度。
