Types of Steering Systems
- Mechanical steering pump: no assistance, fully manual
- Hydraulic power steering pump: use hydraulic pressure for assistance
- Electric power steering pump: motor-driven, more efficient and intelligent
How a Power Steering Pump Works
The steering wheel pump makes steering easier. In hydraulic power steering (HPS) systems, the pump pressurizes fluid and delivers it to the steering gear.
Working Process:
- Engine drives the pump via a belt
- Pump pressurizes hydraulic fluid
- High-pressure fluid flows to steering gear
- Assists steering movement
- Fluid returns and circulates
