Differential Toyota Corolla 120 with automatic transmission
Description
The differential in a Toyota Corolla 120 with automatic transmission performs the function of distributing torque between the drive wheels, allowing them to rotate at different speeds when cornering. This is necessary because the outer wheel must rotate faster than the inner wheel when moving in an arc.
Types of differentials
The Toyota Corolla 120 with automatic transmission can use two types of differentials:
* Open Differential: The simplest type of differential that allows the wheels to rotate independently of each other. This causes the inside wheel to slip when cornering.
*Limited Slip Differential (LSD): A more complex type of differential that limits the difference in rotational speed between the wheels, providing better traction.
Design
The differential of a Toyota Corolla 120 with automatic transmission usually consists of the following components:
*Bevel Gears: Two bevel gears that rotate in opposite directions and transmit torque from the transmission to the wheels.
*Differential Box: Housing that houses the bevel gears and other components.
* Planetary Gears: Gears that allow wheels to rotate at different speeds.
* Friction Discs: Discs that compress to limit wheel slip in a limited slip differential.
Service
The differential is usually serviced by changing the oil in the differential and checking the oil level. It is recommended that a limited slip differential use a special oil that provides the necessary coefficient of friction for the differential to function properly.
