1. STRUCTURE
(1) Steering Cylinder
(2) Steering Controller
(3) Oil Cooler
This machine is provided with hydrostatic power steering.
In the full hydrostatic power steering, the steering controller (2) is connected to the steering cylinder (1) by
hydraulic piping. Accordingly, it does not have mechanical transmitting parts such as steering gear, pitman arm, drag
link, etc.. Therefore, it is simple in construction. This steering system consists of the oil strainer (7), hydraulic pump
(8), flow priority valve (9), steering controller (2) and steering cylinder (1) etc..
Flow priority valve divides the oil into two direction. One is the control flow to power steering (constantly 10 L/min.,
2.64 U.S.GPM, 2.20 Imp.GMP), and the other is excessive flow to control valve of implement lift control.
By operating the power steering body, the required amount of oil is fed to the steering cylinder (1).
