Universal base plate for heavy-load two-wheel differential robot

The invention relates to a universal base plate for a heavy-load two-wheel differential robot. The universal base plate comprises a bottom plate. A suspension driving device is mounted in the middle of the bottom plate. Multiple support wheel devices are arranged on the portion, on the periphery of the suspension driving device, of the bottom plate. The suspension driving device comprises a middle shell and two driving wheel frames correspondingly located on the two sides of the middle shell. A connecting rod is arranged between each of the two sides of each driving wheel frame and the middle shell, and a four-connecting-rod mechanism is formed. Connecting end heads are correspondingly mounted on the tops of the two driving wheel frames. An adjustable spring is arranged between each connecting end head and the middle shell. The upper end of each adjustable spring is hinged to the top of the middle shell, and the lower end of each adjustable spring is hinged to the corresponding connecting end head. Driving wh
