The invention discloses a tunnel concrete mixer truck driven by multiple motors. A motor is used for replacing an internal combustion engine to serve as power of a hydraulic system, and the defects of low energy utilization rate and the like of power driving of the hydraulic system are overcome, namely direct motor driving is adopted. The special combined wheel of the steel wheel and the tire wheel can be suitable for running on a track and can also be suitable for running on a concrete pavement of a tunnel wall; and the basic performance of constant power control of the new variable frequency motor is exerted, so that the same driving wheel adapts to different torque requirements of two kinds of driving, and the situation that different wheels are driven by different hydraulic motors originally is avoided so as to cope with repeated configuration of different road surfaces. The high-efficiency feed function of the variable frequency motor is utilized, so that the equipment is particularly energy-saving when running on a rail; and a unified cooling system is also used, so that the cooling requirements of multiple electric drive systems are economically met. The energy-saving measures greatly reduce expensive batteries or increase endurance mileage. In addition, by means of control over the output rotating speed and torque, high working efficiency is achieved economically.

    本发明公开了一种多电机驱动的隧道混凝土搅拌车。它不只是用电机取代内燃机作为液压系统的动力,而是摒弃了液压系功率驱动之低能量利用率等缺陷——采用直接电机驱动。它的钢轮及轮胎轮的特殊组合轮,既可适用轨道行驶、又可适用隧道壁之混凝土路面行驶;以及发挥新变频电机的恒功率控制的基本性能,使同一驱动轮适应二种行驶的不同扭矩要求,从而避免了原用不同液压马达驱动不同的轮,以应付不同路面的重复配置。它利用变频电机的高效馈电功能,使设备在轨道行驶特别节能;还用了统一的冷却系统,经济地满足多电驱系统的冷却需要。前述节能措施大幅减少昂贵的电池或增加续航里程。它还利用对输出转速及扭矩的控制,经济地发挥了高工作效率。
