How Power Steering System Works? | Complete Explanation in Hindi

A steering system of an automobile is an integral part of vehicle dynamics of a vehicle in which a series of mechanical components having certain important angles comes together to steer the front wheels of the vehicle according to input provided by the driver through steering wheel.
The power steering system is the advanced steering system in which the effort required to steer the front wheels of the vehicle side to side is reduced by using intermediate electric or hydraulic devices that multiplies the force applied by the driver through steering wheel in order to achieve smooth and quick directional change of the vehicle.
Important Components of Power Steering System-
1. Steering mechanism- Usually rack and pinion steering mechanism is used in power steering in which the rotational motion of the steering wheel is converted into the transverse motion of the wheels by a set of constantly meshed worm gears called rack that provide transverse motion and a pinion that provides rotational motion.
2. Linkages - They are the mechanical constraints that provide relative motion between 2 components, the type of linkages used in power steering is the tie-roads that connects the rack to the knuckle of the wheel in order to transfer the transverse motion of the rack to the wheels.
3. Power device- A force multiplying device (either hydraulic or hybrid or electric) is used to multiply the steering wheel force in order to reduce steering efforts. This device is attached with the pinion of the rack and pinion mechanism.
4. Steering wheel- A round steering wheel is used inside a cockpit (operated by the driver) that provides the rotational steering input to the further steering devices in order to steer the vehicle.
Working of Power Steering System:
1. Hydraulic Power Steering System
In this type of power steering system, the hydraulic force is used to multiply the steering input force in order to smoothen the steering of the front wheels, this hydraulic force is generated by a series of components that includes hydraulic cylinder, rotator hydraulic pump, hydraulic lines, highly compressed hydraulic fluid and a coupling mechanism that can couple this hydraulic system with rack of the steering system.
When the driver provides input by rotating the steering wheel, the hydraulic pump driven by the engine starts pumping the highly compressed hydraulic fluid through lines.
The hydraulic pressure produced by the pump enters the hydraulic cylinder which in turn applies pressure over the cylinder’s piston.
The piston which is under high pressure starts moving from one end to the another which in turn pushes the further fluid through lines, with this movement of piston the input force applied by the driver is multiplied several times.
This high pressure fluid sent by the hydraulic cylinder then applies the pressure to the attached pinion through the coupling mechanism which in turn applies high force to the rack gear and the steering action in the front wheels takes place.
2. Hybrid or Semi Hydraulic Power Steering System
In this type of power steering system the hydraulic pump driven by the engine from the hydraulic power steering system is replaced with electric pump which makes it more reliable, this is the only modification made rest the working of this system is same as the hydraulic power steering system mentioned above.
3. Electric Power Steering System
This system is latest of all the steering system mentioned above in this type of steering system as we have already discussed the force multiplication is the function of the electric motor instead of hydraulic fluid and the working of this system is as follows-
When the driver gives input through the steering wheel the electronic sensors attached to the steering column reads the input and sent them to the electric control unit of the vehicle.
The ECU of the vehicle analyses these inputs and sent the voltage signal to the electric motor placed at the end of the steering column whose gear is in constant mesh with the pinion gear.
Due to these voltage signals sent by the ECU the motor which is driven by the battery of the vehicle starts and provides the particular torque according to the value of the voltage signals received
After the motor starts the gear which is in constant mesh with the pinion gear starts transmitting the multiplied torque to the pinion gear which in turn applies this torque to the rack through which it is attached.
With this torque applied by the pinion over rack , rack moves which in turn steer the front wheels (with the help of the tie rods attached) as per the requirement.

Good job. I have an ml55 amg 2000 I need to top off the fluid. After putting the seafoam trans tune in. Can any any power fluid be used? I don't want to spend the money on CHF 11S. I just need a little. Can I use prestone... .european?
