5-6 Fully hydraulic steering system
The tractor is adopted fully hydraulic steering system. It mainly consists of BZZ1-80 hydraulic
steering gear, hydraulic oil tank, HLCB-D08/06 pump, hydraulic oil cylinder. Its theoretical diagram
please see Fig. 5-7, the structural diagram please see Fig. 5-8. The flow rate of hydraulic oil is a
constant 6ml/rev and 8L/min. The rated working pressure is 10MPa.
From the pump 12 constant flows hydraulic pressure oil to hydraulic steering gear 2, and the steering
wheel is motionless, then the hydraulic pressure oil returned oil pipe 10 from steering, and flows to
hydraulic oil tank 23. The steering wheel is working, the hydraulic oil flows into the left side or
right side of steering cylinder 16, which make the direction adjusted.
