What is Power Steering

gobdp.com

You must have heard the name of power steering. Nowadays power steering is used inside the new vehicles. The biggest advantage of using it is that turning the car becomes very easy. Friends, if you are ever sitting inside a turbulent place, then you will know that when the turbine has to bend, the sweat of the coward will be lost. For this, he has to apply a lot of force. However, if the vehicle is powered by a power steering, it can be easily bent by hand. So now you have some understanding of what power steering is. Friends, its job is that we can bend the vehicle easily.

Hydraulic or electric actuators control the energy and require less effort when the diver has to bend the vehicle. Meaning that half the energy is used by it itself. Hydraulic power steering systems in cars increase steering effort through an actuator, a hydraulic cylinder that is part of a servo system. These systems have a direct mechanical connection between the steering wheel and the linkage.

There are many types of power steering systems. Actuators are used inside the hydraulic power steering system. While motors are used inside the electric power steering system, in addition to this, a sort of mix system is used inside the larger vehicles. हाइड्रोलिक They require both hydraulic and electric systems to operate the power steering.

Facts about power steering

1. The first power steering system on an automobile was built by an individual inside 1876. But very few people know about him.

2. Then in 1903 AD, a motor was placed inside the front to bend the wheels of a truck. Which assisted the driver to bend the truck's tires.

3. Robert E., a resident of Pittsburgh, Pennsylvania. Twyford issued its patent on 3 April 1900 for its four-wheel-drive system.

4. Francis W. Davis, an engineer with Pierce-Arrow's truck division, attempted to discover how power steering could be made easier.
Then for the first time within 1926 AD, his invention was publicly publicized. Power steering was made much better after Davis moved to General Motors. But the company calculated that it was found that it was too expensive.

5. बाद After that Davis entered into an agreement with a company called Bendix and this company used to make a stock of vehicles. At the same time, within the Second World War, the need for electricity was increased more for the conduct of vehicles.

6. Power steering was first launched by the Chrysler Corporation on the 1951 Chrysler Imperial called "Hydragide". And his public performance was also done.

7. General Motors then introduced the 1952 Cadillac with the power steering system that Davis had given the company 20 years earlier.

8. Charles F. of Detroit Hammond filed a patent in 1958 for improvements inside steering in Canadian intellectual property.

Now the full vehicles come. Power steering is definitely provided inside them. However, in light vehicles, there is no need for power steering.

Hydraulic power steering system

Hydraulic systems are used to control the steering inside this system. Hydraulic pressure is usually given by a Gerotor or rotary vane pump. Valves are used to control the flow in the steering wheel cylinder. The more torque the driver applies to the steering wheel and column, the more fluid comes through the valve cylinder. There is also a sensor to measure the Troc applied to the steering wheel. A torsion bar is used inside it. is.

And when the bottom end is rotated, the bar will be bent proportionally to the torque applied. The difference in position between the opposite ends of the torsion bar controls a valve. The valve allows the cylinder to flow which provides steering support; The higher the "bend" of the torsion bar, the greater the force.

‌‌‌The hydraulic system is a type of positive speed. Steering at high engine speed will work well. The steering booster is tuned inside it. Because sometimes the power steering goes bad. And its malfunction can cause the man steering to stop working. Steering boosters are used to avoid this. Apart from this, it is very necessary to inspect the liquid-filled inside it from time to time.

DIRAVI Variable-Assist Power Steering

It was invented by Citron of France. There is no connection between the steering wheel and the roadwheels when the car's hydraulic system is pressurized. The system was first introduced in 1970 in the Citroën SM and was introduced in the UK In 'VariPower' and in America as 'SpeedFeel'. Tell you that the pressure applied inside this system is proportional to the speed of the road. Meaning when the car is at high speed there is no need to exert too much force on the steering. In contrast, more force has to be applied.

What is a power steering electro-hydraulic system

What is power steering? So far, we have learned about many things. Apart from the power steering given above, there are some other types of power steering as well. Which also has an electro-hydraulic system. This system is known as Hybrid. A pressure inside it comes through an electric motor.

1. In 1965, Ford experimented with Mercury Park Lane's fleet of "wrist-twist instant steering", which replaced the traditional large steering wheel with two 5-inch (127 mm) rings, a sharp 15: 1 gear ratio, and an electric Replaced with hydraulic.

2. In 1988, the Subaru XT6 received some further improvements inside a unique Cybrid adaptive electro-hydraulic steering.

3. In 1990, Toyota introduced its second-generation MR2 with electro-hydraulic power steering.

4. The electro-hydraulic system is used in many cars. Such as Volkswagen, Audi, Peugeot, Citroën, Seat, Skoda, Suzuki, Opel, Mini, Toyota, Honda, etc.

What is a power steering electric system

An electric motor is used inside the motorized power steering (MDPS). Also, a sensor is used inside it. Troc is applied through the computer module motor. It differs according to the driving conditions. Allows applying different forces. There is no need to fear even if the EPAS system fails. Because under such a situation the steering of the vehicle can be used as common steering. However, it depends on the skill of the driver. The advantage of the electric system is that it works to increase the efficiency of the engine.

Because the hydraulic pumps inside it do not run continuously. And many high-pressure hydraulic hoses between the hydraulic pumps mounted on the engine, and steering gear is mounted on the chassis. It is also very easy to maintain.

1. In 1986, NSK put EPS into practical use for battery forks.

2. In the Koy years Koyo Seiko (the current JTEKT), NSK had developed a pillar system for towers, sold only in Japan. The first electric power steering system appeared on the Suzuki Servo in 1988.

Electrically variable gear ratio system

1. In 2000, the first electric power variable gear ratio steering (VGS) system was given in the Honda S2000 Type V.

2. Toyota introduced a variable gear ratio steering on the Lexus LX and Landcruiser Cygnus.

3. In 2003, BMW introduced the "Active Steering" system on the 5 Series.

Some drawbacks of hydraulic power steering

Friends, by now you know what power steering is. But let me tell you when the electric power steering system did not come. Hydraulic power steering was then used. But there were some shortcomings inside this system. And let us know the shortcomings of the electric power steering system. About them too. 4

Belt and fluid problem

Fluids were commonly used inside hydraulic systems. And he needed to change it again and again. In addition, the belts used in it used to deteriorate frequently. This was also a major drawback of this system.

Makes the vehicle heavy

There is a lot of extra weight inside the hydraulic power steering. And by the way, it also used to add unnecessary weight inside the vehicle. But the advantages are low due to the electric power steering being lighter.

High fuel consumption

The engine energy is usually used to run this system. And because of its continuous running, it also works to increase fuel consumption unnecessarily. But there is nothing like this inside the electric power steering. It works by a sensor. At low speeds the steering is light. So that the driver can bend the car easily and it is heavy at high speed. So that the car can run in a stable manner.
