How Hydraulic Power Steering Works

Here's how hydraulic power steering works on your car!
Check out my behind-the-scenes of the making of this video here:
• Behind the Scenes of Y...
Hydraulic power steering is used to assist the turning of the wheels on modern heavy vehicles. A power steering pump provides pressure to hydraulic lines that connect to the steering rack. The rotary valve uses driver input to determine which side of the steering rack to send hydraulic fluid to. The rack has a piston inside that moves in the direction that high pressure fluid is applied. Finally, the hydraulic fluid completes the circuit back to the reservoir to be cycled around again.

Ha ha ha ha, I finally understand how this mechanism works. I always wondered how the power assist knew when to stop, ie how to prevent pressure assist from steering beyond where the driver wants to go. It's all about that little torsion bar. As soon as the steering wheel is released, the torsion bar springs the holes back to a neutral position so no more pressure goes to the side you're turning towards. Genius.

@speedkar99 4 жыл бұрын

It's so intricate yet simple on how that little torsion bar does its job!

@juvenildr 3 жыл бұрын

Yes torsion bar backs to neutral position but how it is turned when moving? is there a clutch like system ? if released how the gripping is over? i understand the mechanism but i wonder the details.

@Jamie-cz2xu 3 жыл бұрын

@@juvenildr it puts pressure on the side of the steering that you want to turn it, it wont turn the rack by itself, it just puts pressure there to help you turn the steering easier.

Hello from India. Very informative video, especially the torsion bar thing. I have a strange issue with my humble ford fiesta with hydraulic PS. I find steering assistance is a bit more than I would have liked. Car turns tack sharp but I'll love to put some more effort in turning. I got a new rack, suspension kounts, struts to fix some of the other issues but this one is giving me a tough time. Any suggestions?

hi there, You made a very detailed video and many thanks for explaining that. I have a question regarding the failure you mentioned at 6:12. That failure could be due to a torsion bar or hydraulic pump or steering rack seal leakage, I am facing this hard steering problem in my car these days and I am wondering if you can help me answer this in order to fix my car. Many thanks Regards

If you blow piston with low pressure air there will be allot of blow-by the rack piston hard seal ring . Fluid pressure expands the seals I suppose to a tighter clearance.

Thanks for your educational video. Could you help me by identifying a noise from the pump. It´s been replaced by a used 71000 km pump. The same noise of high strain state to pump persists. It appears when not turning. When turning the wheel, the noise changes loader and quieter and it gets a little stuck at high sound parts. It happens more when the system in cold and makes no noise at all when warm. The noise returns after shutting down for a few minuts. No leaks. Fluids are new. The left front wheel was replaced because of rim damage, and same wheel´s control control rod´s end part was replaced. Perhaps the new pump was damaged due to lack of bleeding as it was changed by the mechanic? Or is the center rod bad? Chevrolet Matiz 2005 1.0 L has no electric motors in the steering column.
