The invention provides an electric tractor with an adjustable gravity center. The electric tractor mainly comprises a gravity center adjusting mechanism, a charging and DC-DC all-in-one machine, a power battery, a driving motor, an instrument panel, a force-measurable suspension device and a chassis. The power battery is installed above the gravity center adjusting mechanism and can adjust the gravity center position of the electric tractor in real time; the charging and DC-DC all-in-one machine is connected with the power battery and is used for charging the power battery and converting the voltage of the power battery into available voltage of vehicle-mounted electrical equipment; the driving motor serves as a whole vehicle power device and is mounted on a lower bottom plate; the instrument panel is installed below a steering wheel and can display the vehicle speed, the electric quantity information of the whole power battery and a single power battery and fault information in real time; the force-measurable suspension device has a force measuring function and can detect the traction resistance borne by the electric tractor in real time during tillage. On the basis of an originaldiesel tractor, electrokinetic transformation is conducted, the electrokinetic process is accelerated, environmental protection is facilitated, the gravity center of the electric tractor is adjustable, and the stability and traction performance of the electric tractor can be improved.

    本发明提供了一种重心可调节的电动拖拉机,其主要组成部分包括重心调节机构、充电和DC‑DC一体机、动力电池、驱动电机、仪表盘、可测力悬挂装置、底盘。动力电池安装在重心调节机构上方,可实时调节电动拖拉机重心位置;充电和DC‑DC一体机与动力电池相连,用于为动力电池充电和将动力电池电压转化为车载电气设备可用电压;驱动电机作为整车动力装置安装在下底板上;仪表盘安装于方向盘下方,可实时显示车速、动力电池整体和单体的电量信息以及故障信息;可测力悬挂装置具有测力功能,可实时检测耕作时电动拖拉机所受牵引阻力。本发明在原有柴油拖拉机的基础上进行了电动化改造,加快电动化进程且有利于环保,电动拖拉机重心可调,可提升电动拖拉机的稳定性和牵引性能。
