While having a discussion, Technician A says that the purpose of a differential is to transfer power from the driveline to the wheels. Technician B says that it increases engine torque by providing a final drive gear reduction, usually of about 2.5 to 3.5 to 1. Who is correct?

Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. Technician A is correct in stating that the differential's purpose is to transfer power from the driveline to the wheels, allowing them to rotate at different speeds when necessary. Technician B is also correct in stating that the differential can increase engine torque through a final drive gear reduction, which is typically in the range of 2.5 to 3.5 to 1. This gear reduction allows for more effective use of the engine's power in driving the vehicle.
