The invention discloses a high-speed electric motorcycle dual-motor driving system which is composed of two control systems, two permanent magnet synchronous motors in signal connection with the two control systems, a dual-motor connecting system, a synchronous wheel and synchronous belt transmission system connected with the dual-motor connecting system, and a rear axle output system connected with the synchronous wheel and synchronous belt transmission system. Only one motor is needed to work in a rated state at low speed and low torque, the efficiency point is in an efficient area, the efficiency is generally 91%-95%, and the energy consumption is very low. When high speed, acceleration and large climbing torque are needed, the two motors work at the same time, at the moment, the state is in an efficient area, the efficiency is generally 91%-95%, and the efficiency is improved by about 20%. The whole power system always runs in a high-efficiency area, so that the energy consumption is greatly reduced, and the endurance mileage of the vehicle is improved. And meanwhile, the power system basically operates in a rated state, so that the failure rate is reduced, and the service life is prolonged.
本发明公开了一种高速电摩双电机驱动系统,由两台控制系统、与两台控制系统分别信号相连的两台永磁同步电机、双电机连接系统、与双电机连接系统相连的同步轮同步带传动系统、与同步轮同步带传动系统相连的后轮轴输出系统组成。本发明低速低扭矩时只需要一台电机在额定状态下工作,其效率点在高效区内,效率一般多是在91%~95%之间,能耗就很低。需要高速、加速及爬坡大扭矩时由两台电机同时工作,这时的状态又在高效区内,效率一般又是在91%~95%之间,效率提高了20%左右。整套动力系统一直在高效区内运行,大大减低能耗,提高了车辆的续航里程。同时动力系统基本在额定的状态下运行,其故障率减少,使用寿命加长。
