Definition and Components

• Components of vehicles drive system
• Major components
• Engine
• Transmission
• Drive shafts
• Differentials

4
Engine

• Burns fuel and converts energy to motion
• Many types of engines
• Most cars use internal combustion engine
• Also use 4 stroke combustion cycle

5
Transmission

• 2 types of transmission
• Every car possesses a transmission
• Gear ration between engine changes during
  acceleration and deceleration
• Transmission allows you to change gears
• Change gear so engine stay below redline on rpm
  meter

6
Drive Shaft

• Used to turn differentials
• Connects the transmission to the differentials
• Runs perpendicular to the axles
• In 4X4 it runs through differential in the center
• no drive shaft in front wheel drive

7
Differentials

• Has three jobs
• Aims engine power at wheels
• Acts as final gear reduction
• Allows wheels to rotate at different speeds
• Helps a car turn
• No differential will cause wheels to lock
  together

8
Conclusion

• Powertrain consists of all the components of a
  vehicle drive system
• Is comprised of
• Engine
• Transmission
• Drive Shaft
• Differentials
