Steering Ratio Formula:
| From: | To: |
The Steering Ratio is the ratio of the angle turned by the steering wheel to the angle turned by the wheels of a vehicle. It determines how much the steering wheel needs to be turned to achieve a certain wheel angle.
The calculator uses the Steering Ratio formula:
Where:
Explanation: The formula calculates the steering ratio by dividing the steering wheel radius by the pinion pitch circle radius.
Details: The steering ratio affects vehicle handling, maneuverability, and driver effort. A higher ratio provides more precise control but requires more steering wheel turns, while a lower ratio offers quicker response but less precision.
Tips: Enter steering wheel radius and pinion pitch circle radius in meters. Both values must be positive numbers greater than zero.
Q1: What is a typical steering ratio range?
A: Typical steering ratios range from 12:1 to 20:1 for passenger vehicles, with sports cars having lower ratios and larger vehicles having higher ratios.
Q2: How does steering ratio affect driving?
A: Lower ratios provide quicker steering response but require more effort, while higher ratios offer easier steering but slower response.
Q3: Can steering ratio be adjusted?
A: Steering ratio is typically fixed in most vehicles but can be modified through aftermarket steering gear or variable ratio steering systems.
Q4: What's the difference between steering ratio and steering gear ratio?
A: Steering ratio refers to the overall ratio from steering wheel to wheels, while steering gear ratio specifically refers to the ratio within the steering gearbox.
Q5: How does steering ratio relate to turning circle?
A: While related, steering ratio primarily affects steering response and effort, while turning circle is more directly related to the vehicle's wheelbase and steering geometry.
