According to the pure electric loader-digger and the torque distribution method, a traditional gearbox structure is abandoned, a front walking motor and a rear walking motor are adopted to drive a front axle and a rear axle respectively, and the front axle and the rear axle are driven according to the front axle load, the rear axle load, an accelerator signal and a brake pedal signal during running. Torque distribution of the front walking motor and the rear walking motor is carried out, slipping of front and rear wheels can be effectively avoided, four-wheel drive can be directly adopted at a high speed, and the driving force is improved.

    本发明公开了一种纯电动挖掘装载机及扭矩分配方法,本发明摒弃了传统的变速箱结构,采用前行走电机和后行走电机分别驱动前桥和后桥,在行驶时,根据前桥载荷、后桥载荷、油门信号和刹车踏板信号,进行前行走电机和后行走电机的扭矩分配,可以有效避免前后轮打滑,并且在高速时可直接采用四驱驱动,提高驱动力。
