The invention relates to the technical field of vehicle engineering, in particular to a double-motor four-wheel-drive trolley which comprises a chassis, a left wheel set and a right wheel set, a secondary reduction gearbox is arranged on the inner side of each tire, an input shaft of each secondary reduction gearbox is fixedly connected with a belt wheel, and the two belt wheels corresponding to the left wheel set are in transmission connection through a first transmission belt. The two belt wheels corresponding to the right wheel set are in transmission connection through a second transmission belt, driving motors are arranged on the inner side of one of the two belt wheels corresponding to the first transmission belt and the inner side of one of the two belt wheels corresponding to the second transmission belt correspondingly, and the two driving motors are connected to the corresponding belt wheels through primary reduction gearboxes correspondingly. Four-wheel driving is achieved through the two driving motors, so that the trolley has the good passing performance and meanwhile has the low production cost; the trolley can steer in situ and has good controllability; the primary reduction gearbox and the secondary reduction gearbox form two-stage speed reduction, so that the limit output torque of each tire can be greatly improved.
本发明涉及车辆工程技术领域,尤其涉及一种双电机四驱小车,包括底盘、左轮组和右轮组,每个轮胎内侧均设有次级减速箱,次级减速箱的输入轴固接有带轮,左轮组对应的两个带轮通过第一传动带传动连接,右轮组对应的两个带轮通过第二传动带传动连接,第一传动带对应的两个带轮中的一个带轮内侧以及第二传动带对应的两个带轮中的一个带轮内侧分别设置有驱动电机,两个驱动电机分别通过初级减速箱连接至对应的带轮。本发明通过两个驱动电机实现了四轮驱动,使小车在具有较好的通过性能的同时兼具较低的生产成本;且小车能够原地转向,具有较好的操控性;初级减速箱与次级减速箱构成两级减速,能够较大程度地提高各轮胎的极限输出扭矩。
