What does power steering in a car mean?
3 Answers
Power steering in a car refers to the use of external power to generate auxiliary force for steering, which reduces the operational force required by the driver on the steering wheel. There are three main types of power steering systems configured in cars: 1. Mechanical hydraulic power steering system; 2. Electro-hydraulic power steering system; 3. Electric power steering system. Maintenance considerations for power steering systems: 1. For mechanical hydraulic systems, ensure the power steering fluid in the reservoir is not insufficient, avoid holding the steering wheel at full lock for too long, and pay attention to whether the steering feels heavy or if there is noise. If such symptoms occur, inspect issues like the V-belt of the oil pump and internal pressure; 2. For electro-hydraulic systems, monitor the fluid level and check immediately if the warning light comes on; 3. For electric power steering systems, the structure is relatively simple, but maintenance isn't something that can be assessed visually. If the steering feels heavy or unresponsive, use instruments for measurement.
Power steering is essentially a device that makes turning the steering wheel easier. I remember the first time I drove an old car without power steering—it took all my strength just to back up. Nowadays, driving is nowhere near that strenuous. It mainly relies on two technologies: hydraulic power steering uses an engine-driven oil pump to generate pressure that assists the steering gear, while electric power steering directly employs an electric motor for assistance. Many new cars now use electric power steering, which is more fuel-efficient and responsive, especially making steering effortless in traffic jams. However, it's important to regularly check the power steering fluid or electrical system. If the steering suddenly becomes heavy or the wheel starts shaking during turns, you should head to the repair shop immediately.
Power steering is a godsend for city drivers! In the past without this technology, making a turn felt like lifting weights at the gym, but now just a light flick of the finger does the trick. There are two types: hydraulic and electric. Hydraulic is the traditional old-school method, relying on engine-driven oil pressure to move the steering gear; electric power steering uses an electric motor for assistance, offering faster response and better fuel efficiency. I especially love how effortless it makes parallel parking, which is particularly friendly for female drivers. However, electric power steering can become sluggish if the voltage is unstable, and hydraulic systems make the steering wheel feel as heavy as lead when there's an oil leak. So if you hear unusual noises during a cold start, it's time to get it checked.
