Vehicle Transmission System Quiz

Where is the 'operating clearance' usually measured in a vehicle transmission system?

• At the gear lever

• At the clutch pedal

• At the differential

• At the drive shaft

Why is it sometimes necessary to adjust a clutch actuation system?

• To increase fuel efficiency

• To enhance the sound of the engine

• To adjust for wear and maintain clearance

• To improve the vehicle's acceleration

What is one reason why a centre plate with a spring hub is employed in a vehicle transmission?

• To increase the gear ratio

• To smooth clutch engagement

• To reduce fuel consumption

• To reduce the noise during gear shifting

What material is used for the construction of the bulk ring in a vehicle transmission system?

• Steel alloy

• Aluminum alloy

• Copper based alloy, phosphor bronze

• Titanium alloy

What is the purpose of the 'screw thread' finish on the surface of the bulk ring?

• To increase friction for better grip

• To prevent rust and corrosion

• To allow for thermal expansion

• To disperse the oil film on the friction surfaces.
