  • 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.

The hydraulic power steering trainer (BST103) 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.
