construction (as shown in Figure 4-33)
2) Full-hydraulic steering system principle
The steering pump is a vane pump. The engine
is directly connected with a power takeoff at
the position of engine power take off, and
keeps running. The steering pump sucks oil from
the hydraulic oil tank and outputs
high-pressure oil to a pilot valve P opening.
The pilot valve has following 5 openings: P,
EF, CF, and Ls. Excessive hydraulic oil of the
steering system returns to the oil tank via EF
opening. CF opening is connected with
full-hydraulic steering gear P opening to
provide high-pressure oil to the steering gear.
Ls opening is connected with steering gear Ls
opening as a control line. When the steering
wheel drives the steering gear to rotate, the
steering gear Ls opening provides a pressure
signal to the pilot valve Ls opening to enable
