What is variable ratio steering?

Variable-ratio steering is a system that uses different ratios on the rack in a rack and pinion steering system. At the center of the rack, the space between the teeth are smaller and the space becomes larger as the pinion moves down the rack.

How do I know if my car has variable ratio steering?

To identify a variable-assist power steering, you may try doing a visual search. You can start that by studying the hydraulic power assist if that uses a droop flow pump. If this pump stays in the same place even with an accelerated engine RPM, that means your vehicle is aided with variable-assist power steering.

How does a variable ratio steering rack work?

Some cars use variable ratio steering. This rack and pinion steering system uses a different number of teeth per cm (tooth pitch) in the centre than at the ends. The result is the steering is more sensitive when it is turned towards lock than when it is close to its central position, making the car more maneuverable.

What are the advantages of variable ratio steering?

The advantage of an electronically controlled variable gear ratio Steering Assembly is that it adjusts to the ideal steering condition for whatever the car’s speed happens to be.

What is C factor in steering?

C-Factor C-Factor is the linear distance travelled by rack in one rotation of the pinion. To make steering system more responsive. The value of C-Factor should be as large as possible But, it should be kept in optimum range to keep the Pinion diameter in limit. C-factor =

Does my car have variable assist power steering?

There should be a Service Parts Identification label. Check the label for the code NV7. If it’s there, then your car has variable power steering.

What is Evo steering?

E.V.O. stands for Electronically Variable Orifice. This component is controlled by an electronic control module that reduces fluid pressure from the power steering pump to the steering gear at highway speeds. Improved high speed handling and road feel is the result.

What are the 6 types of steering system?

6 Types of Steering Wheel

  • Telescope Steering Wheel.
  • Tilt Steering Wheel.
  • Adjustable Steering Wheel.
  • Swing-away Steering Wheel.
  • Steering Wheel With Recirculating Balls.
  • Rack-and-Pinion Steering Wheels.

What is a variable rack?

A variable-pitch racked bar has a row of rack teeth with a middle fixed pitch region and two end fixed pitch regions. A variable-pitch region is interposed between the middle fixed pitch region and each of the end fixed pitch regions.

What is effect of worn out rack and pinion steering gear on TYRE wear and how it can be diagnosed?

If your steering rack and pinion wear out, the steering will feel loose. You will also notice that the car wanders at high speed, and it is hard to keep it in the lane. Also, every road imperfection causes your car to easily move left to the right instead of staying in a straight line.
