Operating a servo motor may incur significant costs.
Power steering, a vital system in modern cars, enhances safety and comfort by assisting in steering. This article provides an overview of power steering, its types, maintenance, and potential issues.
Two primary types of power steering systems are found in cars: hydraulic and electric. The first car model with power steering, introduced by Chrysler in 1951, was hydraulic. Hydraulic power steering consists of a power steering pump, high-pressure cylinder, high-pressure lines, a control valve, a control box, an oil compensator, and other components. On the other hand, electric power steering (EPS) is a modern, efficient, and relatively maintenance-free variant.
Regular inspection and maintenance are essential for both types of power steering systems, particularly hydraulic ones. Hydraulic power steering requires checking the fluid level and changing the power steering oil if necessary. Maintenance for electric power steering is less complex compared to its hydraulic counterpart.
Electrohydraulic power steering (EHPS) uses an electric motor in addition to the components of hydraulic power steering. There are mainly three types of EPS systems: Column Assist EPS, Pinion Assist EPS, and Rack Assist EPS, which differ by their location and method of applying steering assistance.
Several signs may indicate a power steering malfunction. Noise (creaking when turning) or over-sensitivity in the steering wheel can be symptoms. Oil traces around the power steering pump area may indicate a leak, porous lines, or cracks in the power steering fluid reservoir. Foaming in the power steering fluid reservoir can indicate oil loss. If the power steering is heavy or too loose, it may also indicate a malfunction.
If the power steering warning light, displaying a steering wheel with an exclamation mark, lights up in yellow, orange, or red, it's crucial to address the issue promptly. If the light stays on, there can be problems during the next MOT test.
Broken power steering can lead to expensive repairs, ranging from 50 to several hundred euros (as of December 2023). In such cases, it's advisable not to continue driving. Retrofitting power steering is possible, but it is usually not worthwhile due to high costs, which can exceed 1000 euros (as of December 2023).
In conclusion, understanding power steering and its maintenance is essential for ensuring the safety and comfort of your vehicle. Regular checks and prompt action when issues arise can help prevent costly repairs and ensure smooth driving.
