  • Familiarization of (rack and pinion) hydraulic power steering system components and composition.
  • Observation of the interaction between hydraulic power steering components to deliver the required functionality.
  • Observing the relation between the motor speed and the steering resistance.
  • Understanding the function of the pressure relief valve which is used to reduce the pressure applied to the pump when needed.
  • Observing steering ratio, which is the ratio between number of rotations of the steering wheel and the turning angle of the wheels.
  • Hydraulic power steering trainer (AT - 071)
  • Hard copy user manual

The hydraulic power steering trainer is based on a real common steering system of modern contemporary passenger cars, light trucks and SUVs. The trainer is based on a fully functional real vehicle hydraulic power steering with all its necessary components. It would help the trainee understand and notice the conversion of its rotational motion that may come from a steering wheel into linear motion to direct the wheels with the help of an oil pump.

                                     
  • The trainer features hydraulic power steering system mounted inside a robust frame.
  • The unit includes all components required for the (rack and pinion) type hydraulic power steering system operation all connected together to form a complete system , these components include:
    • Rack and pinion gear box
    • Hydraulic pump
    • Oil reservoir,
    • Rotary valve
    • Tie rods of the wheels and etc.
  • The unit simulates the real hydraulic power steering system and includes a steering wheel attached to the steering system to allow introducing the rotational motion produced by the car driver.
  • The hydraulic pump is used to pressurize the fluid (oil) and normally driven by the engine, which provides hydraulic pressure to the steering system.
  • The training system is provided with an electric motor used to drive the hydraulic pump instead of the engine to simulate the engine function.
  • The motor speed can be controlled using a knob fixed on the front control panel to simulate raising the engine speed that will lead to raising the whole system fluid pressure.
  • Additionally , the front control panel includes an ON/OFF switch, emergency switch and a schematic diagram showing the steering system design and components.
  • 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.
