How to Measure and Compare Steering Rack Ratios (mm/rev)

Measuring and comparing steering rack ratios in terms of millimeters per revolution (mm/rev) involves specific procedures to ensure accuracy. The primary method includes physically turning the steering wheel and recording the lateral displacement of the steering rack. This displacement is then divided by the number of wheel revolutions to derive the rack ratio.

To perform this measurement, one must first secure the vehicle and connect a precise dial gauge or digital measuring device along the steering rack. Rotate the steering wheel a known number of turns, typically one or two, and record the total lateral movement of the rack. Repeating this process ensures consistency and reliability of data.

A simplified approach involves the following steps:

1. Lock the steering wheel in neutral position.
2. Turn the wheel a full lock-to-lock, noting the total number of turns.
3. Measure the total displacement of the rack during this turn (in millimeters).
4. Divide the total displacement by the number of turns to calculate the rack ratio (mm/rev).

This method allows comparison across different vehicle models, helping determine how responsive or precise the steering system is, especially in relation to lane change ease.

Standard methods for rack ratio assessment

Assessing steering rack ratio involves precise measurement techniques to ensure accuracy and consistency.
