Most cars need 3 to 4 complete turns of the steering wheel to proceed from lock to lock (from far right to far left). The steering ratio shows you how far to carefully turn the steering wheel for the tires to turn a certain quantity. An increased ratio means you should turn the steering wheel more to turn the wheels a particular quantity and lower ratios supply the steering a quicker response.
Some cars use variable ratio steering. This rack and pinion steering system uses a different number of the teeth per cm (tooth pitch) at the heart than at the ends. The result is the steering can be more sensitive when it is switched towards lock than when it’s close to its central placement, making the automobile more maneuverable.
There are two main types of rack and pinion steering systems:
End remove – the tie rods are mounted on the end of the steering rack via the inner axial rods.
Centre take off – bolts attach the tie rods to the centre of the steering rack.
Rack and pinion steering systems aren’t suitable for steering the wheels on rigid front axles, because the axles move around in a longitudinal direction during wheel travel because of this of the sliding-block guideline. The resulting undesirable relative movement between tires and steering gear cause unintended steering movements. Consequently just steering gears with a rotational movement are used. The intermediate lever 5 sits on the steering knuckle. When the tires are considered the remaining, the rod is at the mercy of pressure and turns both wheels simultaneously, 
whereas if they are turned to the right, part 6 is at the mercy of compression. A single tie rod links the wheels via the steering arm.

Some cars use adjustable ratio steering. This rack and pinion steering system uses a different number of teeth per cm (tooth pitch) at the heart than at the ends. The effect is the steering is more sensitive when it is switched towards lock than when it is close to its central placement, making the automobile more maneuverable.

Rack-and-pinion steering is quickly becoming the most common type of steering on vehicles, small trucks. It is actually a pretty simple mechanism. A rack-and-pinion gearset is definitely enclosed in a metallic tube, with each end of the rack protruding from the tube. A rod, called a tie rod, connects to each end of the rack.
The pinion gear is mounted on the steering shaft. When you change the steering wheel, the apparatus spins, shifting the rack. The tie rod at each end of the rack connects to the steering arm on the spindle.
The rack-and-pinion gearset does two things:
It converts the rotational movement of the steering wheel in to the linear motion needed to turn the wheels.
It offers a gear reduction, making it easier to turn the wheels.
On most cars, it takes 3 to 4 complete revolutions of the steering wheel to help make the wheels turn from lock to lock (from far left to far right).
The steering ratio may be the ratio of what lengths you turn the tyre to how far the wheels turn. A higher ratio means that you have to turn the tyre more to have the wheels to turn a given distance. However, less effort is necessary because of the bigger gear ratio.
Generally, lighter, sportier cars have decrease steering ratios than larger vehicles. The lower ratio provides steering a quicker response — you don’t need to turn the tyre as much to find the wheels to switch a given distance — which is a desired trait in sports vehicles. These smaller cars are light enough that even with the lower ratio, the effort necessary to turn the tyre is not excessive.
Some cars have variable-ratio steering, which runs on the rack-and-pinion gearset that has a different tooth pitch (number of teeth per “) in the center than it has on the exterior. This makes the car respond quickly when starting a convert (the rack is close to the center), and also reduces effort close to the wheel’s turning limits.
When the rack-and-pinion is in a power-steering system, the rack has a slightly different design.
Area of the rack contains a cylinder with a piston in the middle. The piston is connected to the rack. There are two liquid ports, one on either side of the piston. Providing higher-pressure fluid to one part of the piston forces the piston to go, which in turn techniques the rack, offering the power assist.
Rack and pinion steering uses a gear-established to convert the circular movement of the steering wheel in to the linear motion required to turn the tires. It also offers a gear reduction, so turning the wheels is easier.
It functions by enclosing the rack and pinion gear-set in a steel tube, with each end of the rack sticking out from the tube and linked to an axial rod. The pinion gear is mounted on the steering shaft so that when the tyre is turned, the gear spins, moving the rack. The axial rod at each end of the rack connects to the tie rod end, which is attached to the spindle.
