Open Differential Explained

The video tutorial explains the components and functions of a car's differential system. It begins with the housing and gears, highlighting their roles in protecting and lubricating the internal components. The tutorial then delves into the differential, describing the spider and side gears and their function in allowing wheels to rotate at different speeds. The mechanics of an open differential are detailed, showing how power is transferred from the engine to the wheels, and how the differential allows for speed variation between wheels during turns.

What is the primary function of the main housing in a differential system?

• To connect the engine to the wheels

• To protect internal components and retain lubricating oil

• To enhance the vehicle's fuel efficiency

• To increase the speed of the vehicle

How does a low gear ratio affect a vehicle's performance?

• Decreases both acceleration and fuel efficiency

• Increases both acceleration and fuel efficiency

• Decreases acceleration but increases fuel efficiency

• Increases acceleration but decreases fuel efficiency

What is the purpose of spider gears in a differential?

• To increase the vehicle's top speed

• To connect the engine to the transmission

• To allow axles to rotate at different speeds

• To reduce the vehicle's weight

In an open differential, what happens to the spider gears when the car is moving in a straight line?

• They rotate on their own axis

• They decrease the car's speed

• They increase the car's speed

• They remain stationary on their axis

When a car turns right, how do the wheel speeds change?

• Both wheels rotate at the same speed

• Both wheels stop rotating

• The left wheel slows down and the right wheel speeds up

• The left wheel speeds up and the right wheel slows down
