Transmission & Drivetrain (A2/A3)Câu 24 / 120
A vehicle has a final drive ratio of 3.73:1. This means the:
a.Wheels turn 3.73 times per driveshaft revolution
b.Driveshaft turns 3.73 times for each wheel revolution
c.Transmission has 3.73 forward gears
d.Engine turns at 3.73 percent of wheel speed
Giải thích
A 3.73:1 final drive means the driveshaft (ring-and-pinion input) turns 3.73 times for every one revolution of the axle/wheel. A numerically higher ratio improves acceleration but raises cruising rpm. Ratio is found by dividing ring-gear teeth by pinion-gear teeth.
