6.1.1 Overview
The steering unit is a cycloid full hydraulic steering unit, able to convey the pressure oil from bypass
valve to steering cylinder according to the size of the rotating angle for the steering wheel in a
measuring way, to achieve the rear wheel steering. When engine is flamed out, the oil pump is unable
to supply oil, and steering may be achieved manually. Refer to Fig 6-2 for the schematic drawing of
full hydraulic steering system, and refer to Fig 6-3 for the drawing for the structure of steering unit.
