Final drives

What is the primary function of the final drive and differential assembly in a vehicle?

• To enhance the vehicle's fuel efficiency

• To increase the speed of the vehicle

• To deliver torque to the wheels smoothly

• To reduce the weight of the vehicle

Why are hypoid gear sets preferred over spiral bevel gear sets?

• They have a simpler design

• They require less maintenance

• They are lighter in weight

• They are stronger and have more teeth in contact

What is a characteristic of a hunting gear set?

• It requires no lubrication

• It has a fixed gear ratio

• It allows one pinion tooth to contact all ring gear teeth

• It is used only in front-wheel drive vehicles

How is the gear ratio of a final drive gear set calculated?

• By adding the number of teeth on the ring gear and the pinion

• By multiplying the number of teeth on the ring gear by the number of teeth on the pinion

• By dividing the number of teeth on the ring gear by the number of teeth on the pinion

• By dividing the number of teeth on the pinion by the number of teeth on the ring gear

What happens to the torque distribution when a vehicle is turning?

• The outside wheel rotates faster and receives more torque

• Torque is not distributed to the wheels

• The inside wheel receives more torque

• Torque is evenly distributed to both wheels
