Power transmissionOverview of the drive force
| Calculation of the gear ratio “i” |
| The gear ratio between two gears, is obtained by dividing the number of teeth on the driven gear (Z2), by the number of teeth on the driving gear (Z1). |

| Gears | 5. Road speed | Final group |
driving
gear (primary) | 45 (Z1 = driving gear) | 19 (Z1 = driving gear) |
Driven
gear (secondary) | 34 (Z2 = driving gear) | 60 (Z2 = driving gear) |
| In this way we can find out: |
| iG = Gear ratio = ZG2 : ZG1 = 34 : 45 = 0.756 |
| iA = Transmission ratio for bevel gear assembly = ZA 2 : ZA1 = 60 : 19 = 3,158 |
| It is obtained by multiplying the gear ratios of the longest gear and the differential. |
| itotal. = overall ratio = iG x iA = 0.756 x 3.158 = 2.387 |
| 1)
| Z1 = Number of teeth of driver pinion, Z2 = number of teeth of driven pinion. |
