1. HYDRAULIC CIRCUIT
The model is provided with a full hydrostatic power
steering.
In the hydrostatic power steering, the steering
control is connected to the steering cylinder with only the
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 oil filter
cartridge (5), hydraulic pump (4), steering controller (2),
steering cylinder (1), etc..
By operating the power steering body, the required
amount of oil is fed to the steering cylinder (1).
