The invention discloses a mining dump truck hybrid power assembly system and a control method thereof. The system comprises an engine, a first motor, a second motor and a planet row system. The planet row system comprises a planet row sun gear, a planet row planet carrier and a planet row outer gear ring which are arranged in a meshed mode. An engine is connected with a planet row planet carrier, a planet row sun gear is connected with a first motor, a planet row outer gear ring and a second motor are both connected with a gearbox system, and the gearbox system is connected with an output shaft. A locking mechanism is arranged on the planet row sun gear in an on-off mode. The torque and the rotating speed of the engine are decoupled through the double motors and the planet row system so that it can be guaranteed that the engine works in the optimal economic zone, the engine is started on the gear through stepless speed regulation of the motors, switching between a pure electric mode and a hybrid mode is faster and more stable, and in the gear shifting process, at least one gearbox is in the gear state, and the gear shifting efficiency is improved. Therefore, no interruption of gear shifting power is ensured.
本发明公开一种矿用自卸车混合动力总成系统及其控制方法,该系统包括发动机、第一电机、第二电机以及行星排系统;行星排系统包括啮合设置的行星排太阳轮、行星排行星架以及行星排外齿圈;发动机与行星排行星架连接,所述行星排太阳轮与第一电机连接,所述行星排外齿圈以及第二电机均与变速箱系统连接,所述变速箱系统与输出轴连接;行星排太阳轮上可通断设有锁止机构。本发明借助双电机和行星排系统分别将发动机的扭矩、转速解耦,以保证发动机工作于最优经济区,采用电机无极调速在档启动发动机,使纯电模式和混动模式的切换更快捷、更平稳,在换挡过程中,至少有一个变速箱处于在档状态,从而保证换挡动力无中断。
