Automotive Differential Fundamentals Quiz

What is the primary function of a differential in an automotive application?

• To increase the speed of the vehicle

• To split input energy on two output sides and allow wheels to spin at different speeds

• To reduce fuel consumption

• To control the steering mechanism

Why is it important for a differential to allow each drive wheel to spin at different speeds?

• It improves fuel efficiency

• It is important for smooth cornering

• It increases engine power

• It reduces tire wear only on straight roads

A differential is particularly useful in automotive applications because it:

• Converts the rotational force of an engine into the torque that drives the wheels

• Increases the braking power of the vehicle

• Controls the air conditioning system

• Monitors tire pressure

Why does a front engine with a transaxle and front wheel drive provide improved traction on slippery surfaces?

• Because the engine is lighter

• Because more weight is over the driving wheels

• Because the wheels are larger

• Because the car is lower to the ground

How does the cabin space in a front wheel drive floorpan compare to that in a rear wheel drive floorpan?

• It is smaller in a front wheel drive floorpan

• It is the same in both

• There is more cabin space in a front wheel drive floorpan

• There is less cabin space in a front wheel drive floorpan

Which issue is most likely to occur under hard acceleration in a front wheel drive vehicle with a transaxle?

• Loss of directional control

• Improved braking performance

• Enhanced acceleration

• Increased tire lifespan

Which components combine to engage the desired gears on the output shaft in a manual transaxle gear box?

• Selector rods, selector forks, and synchromeshes

• Brake pads, rotors, and calipers

• Pistons, valves, and spark plugs

• Radiator, fan, and coolant

Which component locks the gears on the main shaft in a transverse engine transaxle to allow the main shaft to rotate?

• Differential

• Synchroniser

• Output shaft

• Pinion gear

In a transverse engine transaxle, how is torque transferred to the differential?

• Directly from the engine

• Through the gear box

• Through the synchroniser

• Through the output shaft only

Explain the role of the synchroniser in the operation of a transverse engine transaxle and how it affects the rotation of the main shaft.

• The synchroniser allows all gears to rotate freely at all times.

• The synchroniser locks a selected gear to the main shaft, enabling the main shaft to rotate.

• The synchroniser transfers torque directly to the differential.

• The synchroniser prevents the output shaft from rotating.
