The all-electric pallet truck comprises a truck body, a standing platform located at the bottom of the rear side of the truck body, an operating handle located at the top of the truck body and a pallet fork located at the bottom of the front side of the truck body, balance wheels are arranged on the two sides of the bottom of the truck body respectively, and a driving assembly is arranged between the two balance wheels; the driving assembly is arranged at the bottom of the truck body, an output shaft of a permanent magnet synchronous motor of the driving assembly is connected with a first bevel gear, meshing of the first bevel gear and a second bevel gear is transmitted to a bevel gear shaft, rotation of the bevel gear shaft is transmitted to a rotating wheel through a sector gear and a rotating shaft flange, and finally the rotating wheel is driven to move the truck. When steering is needed, an output shaft of a steering motor of the driving assembly is connected with a second spur gear, the second spur gear is connected with a first spur gear in a meshed mode, due to the fact that the box body is fixedly connected with the first spur gear, when the steering motor transmits power, the box body and the rotating wheel are made to rotate in the vertical reverse direction, and therefore the carrying vehicle is made to steer.
本发明公开了一种基于永磁同步的全电动托盘搬运车,包括车身、位于车身后侧底部的站立平台、位于车身顶部的操作手柄以及位于车身前侧底部的货叉,车身的底部两侧分别设置有平衡轮,两个平衡轮之间设置有驱动总成;本发明通过在车身的底部设置驱动总成,驱动总成的永磁同步电机的输出轴与第一斜齿轮相连,第一斜齿轮与第二斜齿轮的啮合传递至斜齿轴,斜齿轴的旋转通过扇齿和转轴法兰传递给转轮,最终驱动转轮使搬运车移动;而当需要进行转向时,驱动总成的转向电机的输出轴与第二直齿轮相连,第二直齿轮与第一直齿轮啮合连接,由于箱体与第一直齿轮固定连接,当转向电机传递动力时,使得箱体和转轮沿竖直反向进行转动,从而使得搬运车进行转向。
