Abstract: In this paper the design of the hydraulic systems of working and steering for CA-20 Rear Dump Truck is introduced. The design include four steps. First of all according to the feature of each hydraulic system, we can draw the principle diagrams of the hydraulic systems of working and steering. Then we can calculate the travels of the dumping cylinders and steering cylinders by the angles of dumping and steering. And then we can decide the pressure of each hydraulic system through the maximal force on each system. At last may chose the pumps and other hydraulic parts according to the pressure and the flow of each hydraulic system, The fact has proved that the hydraulic system of the truck is safe, reliable and efficient.
