The invention discloses a symmetric dual-motor central driving system based on an intelligent transmission system. The symmetric dual-motor central driving system comprises a central output part, twosets of box bodies, and variable-speed driving devices. The two sets of box bodies are symmetrically arranged on the two sides of the central output part, the two ends of the central output part are rotationally matched with the box bodies, output shafts are rotationally installed in the two sets of box bodies, and one end of each of the output shafts extends out of the box body and is fixedly connected to the central output part. The variable-speed driving devices are arranged in the box bodies and are driven by motors; power is transmitted through a speed reducing mechanism and a cam clutchmechanism, so that the output shafts are driven to rotate at a low-speed or high-speed transmission ratio. The symmetric dual-motor central driving system has the beneficial effects that when the output load is large, the two motors are involved, so that the acceleration performance and the climbing performance of the vehicle can be improved; when the load is small, only one motor is used for power driving, so that the energy-saving effect is realized. Meanwhile, when the system is applied to the electric two-wheeled vehicle, the balance of the wheels is good, so that the controllability and safety of the vehicle are improved.
本发明公开了一种基于智能传动系统的对称双电机中央驱动系统,包括:中央输出部件;两组箱体,其对称布置在中央输出部件的两侧,且中央输出部件的两端均与箱体转动配合,两组箱体内均转动安装有输出轴,该输出轴的一端穿出箱体并固定连接在中央输出部件上;变速驱动装置,其布置在所述箱体内,变速驱动装置由电机驱动,经减速机构和凸轮离合机构传递动力,能够以低速或者高速的传动比驱动输出轴转动。本发明的有益效果是:在输出负载较大时,让两个电机都介入,能够增加车辆的加速性能和爬坡性能,负载较小时,仅用一个电机进行动力驱动,能够起到节能的作用。同时应用在电动两轮车上时,车轮的平衡性好,有利于提升车辆的操控性和安全性。
