Manual Transmission/Transaxle: Description and Operation

Transmission Ratios i, Calculating

Example





i = Z2 : Z11

iG = gear ratio = ZG2 : ZG1 = 37 : 50 = 0.740

iA = axle ratio = ZA2 : ZA1 = 69 : 14 = 4.929

itotal = total ratio = iG x iA = 0.740 x 4.929 = 3.647

• 1 Z1 = number of teeth on the drive gear, Z2= number of teeth on the driven gear
