WHAT IS THE DRIVETRAIN AND WHAT DOES IT DO?
A car’s drivetrain includes all of the components necessary to transfer the engine’s energy to its wheels in order to make your vehicle move. If you’ve ever talked about rear-wheel drive (RWD) or front-wheel drive (FWD), for example, you’ve talked about a vehicle’s drivetrain.
VOCABULARY BANK
. wheel (rueda) . axle (eje) . SKID (derrapar) . gear (engranaje) . clutch (embrague)
. rear (trasera) . shaft (barra) . STEER (conducir, guiar) . torque (par de fuerzas) . front (delantera)
. SPIN (girar)
ACTIVITIES
1.- What are the four different drivetrains?
________________________________________________________________________________________________
2.- What is the key component to those systems? _________________________________________________________
3.- Why is it so important? Explain.
________________________________________________________________________________________________________________________________________________________________________________________________
4.- What would happen when you take a turn (tomas una curva) if you had a rigid axle attached to two wheels? Explain.
________________________________________________________________________________________________________________________________________________________________________________________________
5.- Complete the definition of “a differential” with the words given. There are two extra words.
axle between both device rear speeds steer
“The differential is a mechanical _________________ placed _________________ the two wheels on an __________________ . It allows __________________ wheels to spin at different ________________ when needed.”

|
1. The most classic drivetrain.
|
|
|
|
|
|
2. The most modern and automated system.
|
|
|
|
|
|
3. The engine and transmission are mounted together (transaxle) and placed at the front of the vehicle.
|
|
|
|
|
|
4. The transmission is placed after the engine.
|
|
|
|
|
|
5. The front wheels are just focused on steering.
|
|
|
|
|
|
6. To drive anywhere, no matter how rough the conditions.
|
|
|
|
|
|
7. Differential integrated in the transaxle.
|
|
|
|
|
|
8. The Transfer Case is the heart of this system.
|
|
|
|
|
|
9. It doesn’t use a Transfer Case. Instead, it uses a multi-plate clutch.
|
|
|
|
|
|
10. More focused on practical and efficient driving.
|
|
|
|
|
|
11. It has wheel speed sensors on the four wheels.
|
|
|
|
|
|
12. When you lock (bloquear) the centre differential, the torque is evenly distributed between the front and rear axles.
