الباور الهايدروليك (العادي) بيتقل مع السرعه عن طريق صمام يقلل تدفق زيت الباور و بالتالي الدريكسيون يتقل.

اذا كان ما تقوله صحيح انه بيتقل مع السرعة العالية يبقى لابد من وجود حساس سرعة يعطيه الاشارة و يكون هذا الحساس مرتبط بسرعة دوران عجل السيارة و ليس سرعة الموتور و هذا ليس موجود فى سيارتى و لم اراه و عجلة القيادة كما هى لا بتتقل و لا بتخف و موضوع انها بتتقل فى السرعات العالية فهذا موجود فعلا فى الباور الكهربائى فقط .

طيب ايه المشكله؟؟ ليه مينفعش يكون فيه سينسور؟!! هوه الكنترول ميعرفش سرعه العربيه؟!! برجاء قراءة المقطع التالي من ويكيبيديا

Most power steering systems work by using a hydraulic system to rotate the vehicle's wheels. The hydraulic pressure is usually provided by a gerotor or rotary vane pump driven by the vehicle's engine. A double-acting hydraulic cylinder applies a force to the steering mechanism, which in turn applies a torque to the wheels. The flow to the cylinder is controlled by valves operated by the steering wheel. There are several common valve systems of varying complexity, but they all allow the steering wheel to turn further than is necessary to simply open a valve. This is done so that the position of the steering wheel corresponds to the position of the vehicle's wheels. As the pumps employed are of the positive displacement type, the flow rate they deliver is directly proportional to the speed of the engine. This means that at high engine speeds the steering would naturally operate faster than at low engine speeds. Because this would be undesirable, a restricting orifice and flow control valve are used to direct some of the pump's output back to the hydraulic reservoir at high engine speeds. A pressure relief valve is also used to prevent a dangerous build-up of pressure when the hydraulic cylinder's piston reaches the end of the cylinder.

Some modern implementations also include an electronic pressure relief valve which can reduce the hydraulic pressure in the power steering lines as the vehicle's speed increases (this is known as variable assist power steering).

شكراً على الإضافة المفيدة دي ، شكراً جزيلاً

كل اللى حضرتك قولته على عينى و راسى بس فعلا ليس عندى فى الباور الهيدروليك اى اتصال بأى كنترول او شى يعرفة مقدار سرعة السيارة و لا عجلة القيادة بتتقل على السرعة العالية كما تقولون تحب احلفلك .

ماهو ذي ما مكتوب حضرتك "some modern implementations ..." ، يعني مش كل الموديلات فيها ، بعض الموديلات الحديثة فقط ، و أكيد مش هتكون في السيارات العادية أكيد هتكون في فئة السيارات العالية .
