The invention relates to a driving walking hydraulic system and a semitrailer chassis, the semitrailer chassis comprises a frame assembly, an axle system, a suspension system, a chassis CAN bus control system, a self-driving wheel set and a driving walking hydraulic system, the driving walking hydraulic system and the chassis CAN bus control system are installed on the frame assembly; the axle system is hinged to the suspension system, and the suspension system is hinged to the frame assembly. The driving walking hydraulic system comprises two steering driving units, two walking driving units and a wheel lifting driving unit, each steering driving unit comprises a rotary motor, the rotary motor is connected with a first multi-way valve through a pipeline, each walking driving unit comprises two walking motors, the two walking motors are connected with a second multi-way valve through pipelines, and the wheel lifting driving unit is connected with the second multi-way valve through pipelines. The wheel lifting driving unit comprises two hydraulic oil cylinders, and rod cavities and rodless cavities of the two hydraulic oil cylinders are communicated with the third multi-way valve through pipelines. The vehicle is reasonable in structural design, can be dragged and independently run, and can solve the problem that the whole vehicle cannot pass due to a small field and the running zero emission requirement in a plant.
