The invention provides a mine truck electric driving system which comprises electric driving structures and an electric control unit connected with the electric driving structures on the two sides, and each electric driving structure comprises a motor set which is arranged close to a wheel on one side and comprises a plurality of motors; the gear box is arranged between the motor set and the wheels; the wheels are arranged on the side, away from the motor set, of the gearbox, and output power of the motor set is transmitted to the wheels through the gearbox to drive the wheels to run; two gears of large speed ratio and large torque and small speed ratio and high rotating speed are achieved through the clutch device and the locking device respectively, the problem of excessive power is solved, cost is reduced, and economical efficiency is improved. A double-planetary-gear structure is adopted in the gear box, and compared with a traditional gear box, the structure is more compact; a plurality of motors in the motor set are high-speed motors, and compared with common motors, the high-speed motors have higher power density, are smaller in size and mass under the same power and can be conveniently arranged in a bridge box. Parts such as a transmission shaft and a differential are saved, and transmission efficiency is higher.

    本发明提供一种矿卡电驱动系统,包括电驱结构及与两侧电驱结构连接的电控单元,电驱结构包括:电机组,电机组靠近一侧车轮设置且包括多个电机;齿轮箱,齿轮箱设置于电机组与车轮之间;车轮,车轮设置于齿轮箱远离电机组的一侧,电机组的输出动力经齿轮箱传递至车轮以驱动其行驶;通过离合装置和锁止装置分别实现了大速比大扭矩和小速比高转速两个挡位,解决了功率过剩的问题,降低了成本,提高了经济性;齿轮箱内部采用双行星齿轮结构,相比于传统齿轮箱,结构更紧凑;电机组中的多个电机均采用高速电机,相比于普通电机拥有更高的功率密度,同功率下体积与质量更小,便于布置在桥箱之内;节省了传动轴和差速器等部件,传动效率更高。
