The hydraulic power steering trainer tends to demonstrate the common steering system of modern contemporary passenger cars, light trucks and SUVs. The trainer is based on a fully functional real vehicle steering with all its necessary components. It would help the trainee understand its and notice it convert rotational motion that may come from a steering wheel to linear motion to direct the wheels with the help of an oil pump.
- The trainer is mounted on a robust frame which can be easily relocated.
- The trainer is a real rack-and-pinion type hydraulic power-assisted steering with its components such as; rack and pinion gear box, pump, oil reservoir, rotary valve and tie rods of the wheels, all connected together.
- The system is functional and includes a small hand wheel attached to the steering system to allow introducing the rotational motion that would have come from the steering wheel by the driver.
- The pump is driven by an electric motor to simulate how it would have been normally driven by the engine through a belt.
- The motor speed can be controlled by a knob fitted on the unit›s panel to simulate raising the engine speed that will lead to raising the whole system fluid pressure and how the pump acts towards the pressure rise by a pressure relief valve.
- The trainee can observe clearly the full operation of the vehicle steering and how by simple mechanism of a rack and pinion connected to a hydraulic circuit can converts the rotational motion of the steering wheel into linear motion needed to turn the wheels easily.
- A detailed and colored diagram for oil path and the construction of the system printed on the unit›s panel to help the trainee visualize the hydraulic paths and how the rotary valve works to distribute the pressurized fluid inside the rack piston according to the torque on the steering wheel.
- The unit also allows observing steering ratio, which is the ratio between number of rotations of the steering wheels and the turning angle of the wheels.
