Talk:Power steering

From Wikipedia, the free encyclopedia

These abbreviations are commonly used for power steering systems:

  • PAS - Power-Assisted Steering
  • EPS - Electric Powehfgjufuyfyifyfr-assisted Steering
  • VAPS - Variable Assist Power Steering

[edit] Hydraulic systems

The article currently states "As the speed of the engine increases, the pressure in the hydraulic fluid also increases, hence a relief valve is incorporated into the system to allow excess pressure to be bled away". This is misleading. It is the flow rate which is automatically increased with rising engine speed. However, because the flow has to pass through the same orifice (known as the "restricting orifice"), the pressure at the pump's outlet increases with engine speed. At a certain engine speed, this pressure causes a flow control valve to open, directing some of the flow back to the pump's inlet. This prevents the steering from operating too quickly. But the key here is flow rate, not pressure. Christidy (talk) 23:00, 26 April 2008 (UTC)

I have now edited the article to reflect this. Christidy (talk) 00:09, 27 April 2008 (UTC)

[edit] 5W-30 instead of power steering fluid

I accidentally put 5W-30 into my power steering fluid reservoir instead of power steering fluid. Will that cause any problems? 24.54.208.177 17:33, 28 August 2005 (UTC)

Uh... Wikipedia is not your Automotive Repair Shop? Pay Attention to what you put where. Get the PS fluid flushed. Tard.

Concerning my additions to chapter of Citroens DIRAVI system. Please do correct my grammar and odd expressions. As DIRAVI is so widely misunderstood, I tried to give even a bit more correct explanation of what is so special about it.

[edit] Electric steering in light vehicles?

I was recently looking up vehicles with the electric steering. So far the heaviest I have found to use it is the Saturn Aura Hybrid. This car weighs 3529 lbs, can it really be considered a "light" vehicle that the article claims electric steering is limited to? I have only seen it installed on I4 engines so far, but if it works on a 3500 pound vehicle, it should be safe to use on cars with V6 engines that generally weigh ~3500 pounds. This covers some light/medium SUV's/Mid size cars, these are definitely not covered under the "light" vehicle category. If anyone else knows of a heavier vehicle using a power steering system, let me know. I believe that the implementation of these devices is not limited to compacts, but will soon cover all mid size cars as well... Another interesting point I believe this section of the article should cover is the fact that Electrical steering systems are almost required in a Hybrid vehicle that operates on its own with the ICE shut off.
