KS00000490 Bosch mechanical steering pump

This Power Steering Pump from Bosch is used in various vehicles and is designed to provide smooth and efficient steering performance. Its technical benefits include improved fuel efficiency and reduced driver fatigue due to its ability to reduce steering effort. Steering pumps are hydraulic pumps used in vehicles with power steering systems to convert mechanical energy into hydraulic pressure. Typically engine-driven via a belt, these pumps force steering fluid to the steering gear or rack-and-pinion assembly. Internal components, such as vanes, rotors, or gears, generate flow proportional to engine speed and driver input. Modern units often integrate a reservoir and may utilize variable displacement to optimize efficiency and steering feel. Failure modes commonly involve internal wear, fluid leakage, or bearing failure, resulting in diminished or absent power steering assist.
