The invention discloses a four-wheel-drive structure of the dual-motor-driven pure electric loader and a control system. The structure comprise a first drive axle and a second drive axle which are used for driving wheels, the first drive axle and the second drive axle are driven by a first drive motor and a second drive motor respectively, and the first drive motor and the second drive motor are connected with different motor controllers. The motor controllers comprise the first motor controller and the second motor controller, and the first motor controller and the second motor controller are both in communication connection with the whole vehicle controller and controlled by the whole vehicle controller. According to the four-wheel-drive structure, all gearboxes are omitted, traditional parts such as an engine and a clutch are omitted, optimal gearbox-free four-wheel-drive stepless speed change is achieved, the whole vehicle controller serves as a whole vehicle brain, the two drive motors are controlled in real time according to comprehensive information such as loads, driver intentions and whole vehicle energy-saving requirements, the comprehensive performance such as the working response speed and the energy consumption of the loader can be greatly improved, the structure is simple, installation is convenient, and meanwhile the reliability of the whole loader is greatly improved.
本发明的一种双电机驱动纯电动装载机四驱结构及控制系统,包括用于驱动车轮的驱动桥一和驱动桥二,驱动桥一和驱动桥二分别被驱动电机一和驱动电机二驱动,驱动电机一和驱动电机二连接不同的电机控制器。电机控制器包括电机控制器一和电机控制器二,电机控制器一和电机控制器二均通讯连接有整车控制器并被整车控制器控制。本发明的四驱结构取消了所有变速箱,也取消了发动机、离合器等传统部件,实现了最佳的无变速箱四驱无极变速,整车控制器作为整车大脑,根据载荷、驾驶员意图及整车节能需求等综合信息实时控制两个驱动电机,可大大提高装载机的工作响应速度、能耗等综合性能,结构简单、安装方便的同时也大大提高了整车的可靠性。
