What This Calculator Does
Compute overall drive ratio from transmission and final drive ratios.
It combines Transmission Gear Ratio, Final Drive Ratio to estimate Overall Ratio.
Formula & Method
Core equations: Overall ratio: GR_{overall}=GR_{trans}\cdot GR_{final}. Wheel speed: \omega_w = \frac{\omega_e}{GR_{overall}}.
Notation used in the formulas: R = Overall Ratio; x_{1} = Transmission Gear Ratio; x_{2} = Final Drive Ratio.
Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
Inputs Used
- Transmission Gear Ratio: Used directly in the calculation.
- Final Drive Ratio: Used directly in the calculation.
