Full-hydraulic steering gear, pilot valve,

hydraulic oil pump, hydraulic oil tank,

steering cylinder, hydraulic pipeline, etc.

The steering cylinder is φ70.

1) Full-hydraulic steering system

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
