Power steering fluid along with power steering system is designed to reduce the effort needed to change the direction of movement of a vehicle using an external power source. Official first servo-related license appeared in 1932 in the United States belonging to Francis W. Davis.

power steering system elements

Power source which is itself the vehicle engine through a belt train pump that is designed to pump fluid under pressure in hydraulic cylinders that control steering wheel.
Force F must be large enough to overcome external resistances, caused by friction between the tire and the tread, which are directly influenced by friction at the axle load that the type tire tread condition.
Considering these factors, hydraulic cylinders and pressure are chosen to be required to give the pump.

Power steering system main elements :

- hydraulic rotary distributor
- pump to act power steering fluid
- the tank of power steering system
- hydraulic cylinder
- power steering fluid
- pressure relief valve

Power steering fluid – how to check

Checking power steering fluid on most cars is easy, although not all cars have this system: if you park alongside a handful and eat ice cream with the other hand, you have power steering.

Steps to check power steering fluid

Find lever hood, usually located under the dashboard. Pull it.
Go in front of the car. Find locked. It is usually located in front bonnet. Click it. As you press, lift and open the hood.

power steering fluid reservoir

Locate the belts. Power steering pump is driven by a wheel and a belt and has a transparent plastic container or metal (usually round) above. Power steering cap will often branded “power steering”.
Check the fluid level by looking to one side of the tank (if clear plastic) or turning them cover (if metal). Some tanks have a small rod of capacity. Normally, you can choose between hot or cold fluid check and there will be suitable for hot and cold levels.
Put the power steering fluid if necessary. Use only the type of power steering fluid under your car consult the car manual and glass of liquid. Some cars require power steering fluid specifically designed for that type of car.

Tips about power steering system

Check power steering fluid level and belt if you hear a squeak when turning the steering wheel completely.
If the direction is stiff, take the car to a mechanic.
Remember that although deviations or vibrations can signal problems with the power steering system, these symptoms may also be related to car tires, suspension, brakes and other problems.

Attention

Power steering fluid does not “consume” – outside of a leak, there is no reason that the liquid level to be low. Fill tank to the right level and check frequently to see if you can find at a lower level. If you continue, then check for leaks and go to the mechanic. An empty power steering pump may be damaged very quickly and cost a lot to be repaired.

How it works power steering fluid along with power steering system

The driver maintain steering wheel in an upright position, the distributor provides the same pressure in each hydraulic cylinder chamber.
When the wheel is rotated hydraulic circuit will take some more pressure. When entering the pressure difference increases the expression of force F and the wheels will brace. Pressure in the circuit is made by a pump. The most common pumps used in the servo are sliding vane and oval room
The amount of power steering fluid put in motion is proportional to pump speed and consequently the engine speed. The pump should be made ??but such as to give adequate flow when the engine running at idle.
Therefore, the high speed modes, the pump gives a much higher rate than necessary power steering fluid. This is because the phenomenon of “Lack of feel” or “lack of sensation.”
The pump is equipped with a pressure relief valve to ensure that pressure does not increase very much when the engine speed increases and increasingly more power steering fluid is circulated through the pump and entire power steering system.
