Four-wheel independent drive transfer trolley

A four-wheel independent drive transfer trolley comprises an objective table, a battery and a master controller. Four wheel type supporting devices are arranged in the bottom face of the objective table. Any one of the wheel type supporting devices comprises a wheel, a wheel suspension gear, a wheel driving mechanism, a wheel mounting base and a wheel steering driving mechanism. Each wheel suspension gear and each wheel driving mechanism are fixedly connected to the corresponding wheel mounting base, each wheel driving mechanism is connected with the corresponding wheel, and each wheel mounting base is connected with the bottom face of the objective table through a rotating shaft and a thrust bearing. Each wheel steering driving mechanism is fixed in the bottom face of the objective table, and each wheel steering driving mechanism is connected with the corresponding wheel mounting base. According to the four-wheel independent drive transfer trolley, needed turning radius limitation in the moving process is greatly reduced, the trolley is suitable for narrow areas with extremely compact space, the four wheels are respectively connected with one independent driving mechanism, when a work environment swings, enough road holding force can be generated, and stable operation can be kept.
